Unity Android log view（Android Debug Bridge）



Android Debug Bridge

Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device. It is a client-server program that includes three components:

• A client, which runs on your development machine. You can invoke a client from a shell by issuing an adb command. Other Android tools such as the ADT plugin and DDMS also create adb clients.
• A server, which runs as a background process on your development machine. The server manages communication between the client and the adb daemon running on an emulator or device.
• A daemon, which runs as a background process on each emulator or device instance.

You can find the adb tool in <sdk>/platform-tools/.

When you start an adb client, the client first checks whether there is an adb server process already running. If there isn't, it starts the server process. When the server starts, it binds to local TCP port 5037 and listens for commands sent from adb clients—all adb clients use port 5037 to communicate with the adb server.

The server then sets up connections to all running emulator/device instances. It locates emulator/device instances by scanning odd-numbered ports in the range 5555 to 5585, the range used by emulators/devices. Where the server finds an adb daemon, it sets up a connection to that port. Note that each emulator/device instance acquires a pair of sequential ports — an even-numbered port for console connections and an odd-numbered port for adb connections. For example:

Emulator 1, console: 5554
Emulator 1, adb: 5555
Emulator 2, console: 5556
Emulator 2, adb: 5557
and so on...

As shown, the emulator instance connected to adb on port 5555 is the same as the instance whose console listens on port 5554.

Once the server has set up connections to all emulator instances, you can use adb commands to access those instances. Because the server manages connections to emulator/device instances and handles commands from multiple adb clients, you can control any emulator/device instance from any client (or from a script).

Enabling adb Debugging

---

In order to use adb with a device connected over USB, you must enable USB debugging in the device system settings, under Developer options.

On Android 4.2 and higher, the Developer options screen is hidden by default. To make it visible, go toSettings > About phone and tapBuild number seven times. Return to the previous screen to findDeveloper options at the bottom.

On some devices, the Developer options screen may be located or named differently.

Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or higher.

For more information about connecting to a device over USB, read Using Hardware Devices.

Syntax

---

You can issue adb commands from a command line on your development machine or from a script. The usage is:

adb [-d|-e|-s <serialNumber>] <command>

If there's only one emulator running or only one device connected, the adb command is sent to that device by default. If multiple emulators are running and/or multiple devices are attached, you need to use the-d,-e, or-s option to specify the target device to which the command should be directed.

Commands

---

The table below lists all of the supported adb commands and explains their meaning and usage.

Table 1. Available adb commands

CategoryCommandDescriptionCommentsTarget Device-dDirect an adb command to the only attached USB device.Returns an error if more than one USB device is attached.-eDirect an adb command to the only running emulator instance.Returns an error if more than one emulator instance is running.-s <serialNumber>Direct an adb command a specific emulator/device instance, referred to by its adb-assigned serial number (such as "emulator-5556").See Directing Commands to a Specific Emulator/Device Instance.GeneraldevicesPrints a list of all attached emulator/device instances.See Querying for Emulator/Device Instances for more information.helpPrints a list of supported adb commands. versionPrints the adb version number. Debuglogcat [option] [filter-specs]Prints log data to the screen. bugreportPrints dumpsys, dumpstate, and logcat data to the screen, for the purposes of bug reporting. jdwpPrints a list of available JDWP processes on a given device.You can use the forward jdwp:<pid> port-forwarding specification to connect to a specific JDWP process. For example:
adb forward tcp:8000 jdwp:472
jdb -attach localhost:8000

Datainstall <path-to-apk>Pushes an Android application (specified as a full path to an .apk file) to an emulator/device. pull <remote> <local>Copies a specified file from an emulator/device instance to your development computer. push <local> <remote>Copies a specified file from your development computer to an emulator/device instance. Ports and Networkingforward <local> <remote>Forwards socket connections from a specified local port to a specified remote port on the emulator/device instance.Port specifications can use these schemes:

• tcp:<portnum>
• local:<UNIX domain socket name>
• dev:<character device name>
• jdwp:<pid>

ppp <tty> [parm]...Run PPP over USB.

• <tty> — the tty for PPP stream. For example dev:/dev/omap_csmi_ttyl.
• [parm]... — zero or more PPP/PPPD options, such as defaultroute,local,notty, etc.

Note that you should not automatically start a PPP connection.

 Scriptingget-serialnoPrints the adb instance serial number string.See Querying for Emulator/Device Instances for more information.get-statePrints the adb state of an emulator/device instance.wait-for-deviceBlocks execution until the device is online — that is, until the instance state isdevice.You can prepend this command to other adb commands, in which case adb will wait until the emulator/device instance is connected before issuing the other commands. Here's an example:

adb wait-for-device shell getprop

Note that this command does not cause adb to wait until the entire system is fully booted. For that reason, you should not prepend it to other commands that require a fully booted system. As an example, theinstall requires the Android package manager, which is available only after the system is fully booted. A command such as

adb wait-for-device install <app>.apk

would issue the install command as soon as the emulator or device instance connected to the adb server, but before the Android system was fully booted, so it would result in an error.Serverstart-serverChecks whether the adb server process is running and starts it, if not. kill-serverTerminates the adb server process. ShellshellStarts a remote shell in the target emulator/device instance.See Issuing Shell Commands for more information.shell [shellCommand]Issues a shell command in the target emulator/device instance and then exits the remote shell.

Querying for Emulator/Device Instances

---

Before issuing adb commands, it is helpful to know what emulator/device instances are connected to the adb server. You can generate a list of attached emulators/devices using thedevices command:

adb devices

In response, adb prints this status information for each instance:

• Serial number — A string created by adb to uniquely identify an emulator/device instance by its console port number. The format of the serial number is<type>-<consolePort>. Here's an example serial number:emulator-5554
• State — The connection state of the instance may be one of the following:
  • offline — the instance is not connected to adb or is not responding.
  • device — the instance is now connected to the adb server. Note that this state does not imply that the Android system is fully booted and operational, since the instance connects to adb while the system is still booting. However, after boot-up, this is the normal operational state of an emulator/device instance.
  • no device — there is no emulator/device connected.

The output for each instance is formatted like this:

[serialNumber] [state]

Here's an example showing the devices command and its output:

adb devicesList of devices attachedemulator-5554  deviceemulator-5556  deviceemulator-5558  device

Directing Commands to a Specific Emulator/Device Instance

---

If multiple emulator/device instances are running, you must specify a target instance when issuing adb commands. To do so, use the-s option in the commands. The usage for the-s option is:

adb -s <serialNumber> <command> 

As shown, you specify the target instance for a command using its adb-assigned serial number. You can use thedevices command to obtain the serial numbers of running emulator/device instances. For example:

adb -s emulator-5556 install helloWorld.apk

Note that, if you issue a command without specifying a target emulator/device instance while multiple devices are available, adb generates an error.

If you have multiple devices available (hardware or emulated), but only one is an emulator, simply use the-e option to send commands to the emulator. Likewise if there's multiple devices but only one hardware device attached, use the-d option to send commands to the hardware device.

Installing an Application

---

You can use adb to copy an application from your development computer and install it on an emulator/device instance. To do so, use theinstall command. With the command, you must specify the path to the .apk file that you want to install:

adb install <path_to_apk>

For more information about how to create an .apk file that you can install on an emulator/device instance, seeBuilding and Running

Note that, if you are using the Eclipse IDE and have the ADT plugin installed, you do not need to use adb (or aapt) directly to install your application on the emulator/device. Instead, the ADT plugin handles the packaging and installation of the application for you.

Forwarding Ports

---

You can use the forward command to set up arbitrary port forwarding — forwarding of requests on a specific host port to a different port on an emulator/device instance. Here's how you would set up forwarding of host port 6100 to emulator/device port 7100:

adb forward tcp:6100 tcp:7100

You can also use adb to set up forwarding to named abstract UNIX domain sockets, as illustrated here:

adb forward tcp:6100 local:logd 

Copying Files to or from an Emulator/Device Instance

---

You can use the adb commands pull and push to copy files to and from an emulator/device instance. Unlike theinstall command, which only copies an APK file to a specific location, thepull andpush commands let you copy arbitrary directories and files to any location in an emulator/device instance.

To copy a file or directory (and its sub-directories) from the emulator or device, use

adb pull <remote> <local>

To copy a file or directory (and its sub-directories) to the emulator or device, use

adb push <local> <remote>

In the commands, <local> and <remote> refer to the paths to the target files/directory on your development machine (local) and on the emulator/device instance (remote). For example:

adb push foo.txt /sdcard/foo.txt

Issuing Shell Commands

---

Adb provides a Unix shell that you can use to run a variety of commands on an emulator or connected device. The command binaries are stored in the file system of the emulator or device, at/system/bin/...

Two of the most common command tools are activity manager (am) and package manager (pm).

You can use the shell command to issue commands, with or without entering the adb remote shell on the emulator/device. To issue a single command without entering a remote shell, use theshell command like this:

adb [-d|-e|-s <serialNumber>] shell <shell_command>

Or enter a remote shell on an emulator/device like this:

adb [-d|-e|-s <serialNumber>] shell

When you are ready to exit the remote shell, press CTRL+D or type exit.

Using activity manager (am)

Within an adb shell, you can issue commands with the activity manager (am) tool to perform various system actions, such as start an activity, force-stop a process, broadcast an intent, modify the device screen properties, and more. While in a shell, the syntax is:

am <command>

You can also issue an activity manager command directly from adb without entering a remote shell. For example:

adb shell am start -a android.intent.action.VIEW

Using package manager (pm)

Within an adb shell, you can issue commands with the package manager (pm) tool to perform actions and queries on application packages installed on the device. While in a shell, the syntax is:

pm <command>

You can also issue a package manager command directly from adb without entering a remote shell. For example:

adb shell pm uninstall com.example.MyApp

Examining sqlite3 databases from a remote shell

From an adb remote shell, you can use the sqlite3 command-line program to manage SQLite databases created by Android applications. Thesqlite3 tool includes many useful commands, such as.dump to print out the contents of a table and.schema to print the SQL CREATE statement for an existing table. The tool also gives you the ability to execute SQLite commands on the fly.

To use sqlite3, enter a remote shell on the emulator instance, as described above, then invoke the tool using thesqlite3 command. Optionally, when invokingsqlite3 you can specify the full path to the database you want to explore. Emulator/device instances store SQLite3 databases in the folder/data/data/<package_name>/databases/.

Here's an example:

adb -s emulator-5554 shell# sqlite3 /data/data/com.example.google.rss.rssexample/databases/rssitems.dbSQLite version 3.3.12Enter ".help" for instructions.... enter commands, then quit...sqlite> .exit 

Once you've invoked sqlite3, you can issue sqlite3 commands in the shell. To exit and return to the adb remote shell, useexit orCTRL+D.

Recording a device screen

The screenrecord command is a shell utility for recording the display of devices running Android 4.4 (API level 19) and higher. The utility records screen activity to an MPEG-4 file, which you can then download and use as part of a video presentation. This utility is useful for developers who want to create promotional or training videos without using a separate recording device.

To use the screenrecord from the command line, type the following:

$ adb shell screenrecord /sdcard/demo.mp4

Stop the screen recording by pressing Ctrl-C, otherwise the recording stops automatically at three minutes or the time limit set by--time-limit.

Here's an example recording session, using the adb shell to record the video and thepull command to download the file from the device:

$ adb shellshell@ $ screenrecord --verbose /sdcard/demo.mp4(press Ctrl-C to stop)shell@ $ exit$ adb pull /sdcard/demo.mp4

The screenrecord utility can record at any supported resolution and bit rate you request, while retaining the aspect ratio of the device display. The utility records at the native display resolution and orientation by default, with a maximum length of three minutes.

There are some known limitations of the screenrecord utility that you should be aware of when using it:

• Some devices may not be able to record at their native display resolution. If you encounter problems with screen recording, try using a lower screen resolution.
• Rotation of the screen during recording is not supported. If the screen does rotate during recording, some of the screen is cut off in the recording.
• Audio is not recorded with the video file.

Table 4. screenrecord options

OptionsDescription--helpDisplays a usage summary.--size <WIDTHxHEIGHT>Sets the video size, for example: 1280x720. The default value is the device's main display resolution (if supported), 1280x720 if not. For best results, use a size supported by your device's Advanced Video Coding (AVC) encoder.--bit-rate <RATE>Sets the video bit rate for the video, in megabits per second. The default value is 4Mbps. You can increase the bit rate to improve video quality or lower it for smaller movie files. The following example sets the recording bit rate to 6Mbps:

screenrecord --bit-rate 6000000 /sdcard/demo.mp4

--time-limit <TIME>Sets the maximum recording time, in seconds. The default and maximum value is 180 (3 minutes).--rotateRotates the output 90 degrees. This feature is experimental.--verboseDisplays log information on command line screen. If you do not set this option, the utility does not display any information while running.

UI/Application Exerciser Monkey

The Monkey is a program that runs on your emulator or device and generates pseudo-random streams of user events such as clicks, touches, or gestures, as well as a number of system-level events. You can use the Monkey to stress-test applications that you are developing, in a random yet repeatable manner.

The simplest way to use the monkey is with the following command, which launches your application and sends 500 pseudo-random events to it.

adb shell monkey -v -p your.package.name 500

For more information about command options for Monkey, see the complete UI/Application Exerciser Monkey documentation page.

Other shell commands

For a list of all the available shell programs, use the following command:

adb shell ls /system/bin

Help is available for most of the commands.

Table 5 lists some of the more common adb shell commands.

Enabling logcat logging

---

The Android logging system provides a mechanism for collecting and viewing system debug output. Logs from various applications and portions of the system are collected in a series of circular buffers, which then can be viewed and filtered by thelogcat command.

You can use the logcat command to view and follow the contents of the system's log buffers. The general usage is:

[adb] logcat [option] ... [filter-spec] ...

You can use the logcat command from your development computer or from a remote adb shell in an emulator/device instance. To view log output in your development computer, you use

adb logcat

and from a remote adb shell you use

logcat

See Reading and Writing Logs for complete information about logcat commend options and filter specifications.

Stopping the adb server

---

In some cases, you might need to terminate the adb server process and then restart it. For example, if adb does not respond to a command, you can terminate the server and restart it and that may resolve the problem.

To stop the adb server, use the kill-server command. You can then restart the server by issuing any other adb command.

Wireless usage

---

adb is usually used over USB. However, it is also possible to use over Wi-Fi, as described here.

1. Connect Android device and adb host computer to a common Wi-Fi network accessible to both. We have found that not all access points are suitable; you may need to use an access point whose firewall is configured properly to support adb.
2. Connect the device with USB cable to host.
3. Make sure adb is running in USB mode on host.

   $ adb usbrestarting in USB mode

4. Connect to the device over USB.

   $ adb devicesList of devices attached######## device

5. Restart host adb in tcpip mode.

   $ adb tcpip 5555restarting in TCP mode port: 5555

6. Find out the IP address of the Android device: Settings -> About tablet -> Status -> IP address. Remember the IP address, of the form#.#.#.#.
7. Connect adb host to device:

   $ adb connect #.#.#.#connected to #.#.#.#:5555

8. Remove USB cable from device, and confirm you can still access device:

   $ adb devicesList of devices attached#.#.#.#:5555 device

You're now good to go!

If the adb connection is ever lost:

1. Make sure that your host is still connected to the same Wi-Fi network your Android device is.
2. Reconnect by executing the "adb connect" step again.
3. Or if that doesn't work, reset your adb host:

   adb kill-server

   and then start over from the beginning.

adb logcat (begins logging)

adb logcat -c (clears the log)

adb logcat > yourlog.txt (dumps the log to a textfile called yourlog.txt) adb logcat > /sdcard/mylogcat.txt  保存log文件到sd卡中 adb logcat > D:/Temp/1.txt

EDIT : Remove the http:// Unity answers puts it there for some reason :/

adb logcat -help (help on all the command line options)

Make sure USB debugging is enabled on the Android device (check underSettings -> Development).

Run adb through the command prompt (with command line argument logcat) that comes with the Android SDK while running the game on the Android, still connected via USB to the computer

adb logcat -s UnityActivityManagerPackageManager dalvikvm DEBUG

Unity提供两种方式让Developer的Android设备连接Profiler进行性能分析：

1、通过wifi，Android设备和计算机处于同一个Wlan中。

2、通过USB ADB

一般情况我们的计算机都是网线，所以我们采用ADB的方式。相比与wifi，ADB也更及时的反应设备性能。

For ADB profiling, follow these steps:    Attach your device to your Mac/PC via cable and make sure ADB recognizes the device (i.e. it shows in adb devices list).    Check the “Development Build” checkbox in Unity’s build settings dialog, and hit “Build & Run”.    When the app launches on the device, open the profiler window in Unity Editor (Window->Profiler)    Select the AndroidProfiler(ADB@127.0.0.1:54999) from the Profiler Window Active Profiler drop down menu. Note: The Unity editor will automatically create an adb tunnel for your application when you press “Build & Run”. If you want to profile another application or you restart the adb server you have to setup this tunnel manually. To do this, open a Terminal window / CMD prompt and enter adb forward tcp:54999 localabstract:Unityinsert bundle identifier hereNote: The entry in the drop down menu is only visible when the selected target is Android.If you are using a firewall, you need to make sure that ports 54998 to 55511 are open in the firewall’s outbound rules - these are the ports used by Unity for remote profiling.
