Android的框架设计有考虑到开机向导这一场景,因此我们实现开机向导参考Android的Provision.apk
Provision: MSM8976/repo/packages/apps/Provision
它的主要作用是作为开机引导用户进行一些基本设置.在原生的 android 系统中,provision非常的简单，只有一个空白的 activity，这个主要就是留给 厂商自己定制开机向导（像 OPPO,VIVO,小米等厂商会让你登陆和注册其账号帐号,连接WiFi等）,因此我们得理解Android的设计意图而进行定制.
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tomorrow_p.setupwizard"> <!--android:sharedUserId="android.uid.system"--> <original-package android:name="com.android.provision" /> <!-- For miscellaneous settings --> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <!--<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />--> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/setupwizard_AppTheme"> <activity android:name=".DefaultActivity" android:excludeFromRecents="true"> <intent-filter android:priority="1"> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.HOME" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.tomorrow_p.setupwizard.SimActivity"> <intent-filter> <action android:name="com.android.provision.SimActivity"></action> <category android:name="android.intent.category.DEFAULT"></category> </intent-filter> </activity> <activity android:name="com.tomorrow_p.setupwizard.OpenActivity"> <intent-filter> <action android:name="com.android.provision.OpenActivity"></action> <category android:name="android.intent.category.DEFAULT"></category> </intent-filter> </activity> </application></manifest>
1. DefaultActivity是原生系统Provision中唯一的activity;配置了category.HOME属性,category.HOME是桌面程序的标记(Launcher程序都会配置);priority=1,配置优先级,这样就会在系统的Launcher之前启动.
2. Provision中的关键代码:
// Add a persistent setting to allow other apps to know the device has been provisioned. Settings.Global.putInt(getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1); Settings.Secure.putInt(getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1); // remove this activity from the package manager. PackageManager pm = getPackageManager(); ComponentName name = new ComponentName(this, WelcomeActivity.class); pm.setComponentEnabledSetting(name, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
这里代码主要设置DEVICE_PROVISIONED标记同时禁止本身Activity组件的功能
API:
void setComponentEnabledSetting (ComponentName componentName, int newState, int flags)
componentName：组件名称
newState：组件新的状态，可以设置三个值，分别是如下：
不可用状态：COMPONENT_ENABLED_STATE_DISABLED
可用状态：COMPONENT_ENABLED_STATE_ENABLED
默认状态：COMPONENT_ENABLED_STATE_DEFAULT
flags:行为标签,值可以是DONT_KILL_APP或者0. 0说明杀死包含该组件的app
主要代码:
以下代码有注释掉跳转到注册和登录账户模块以及调用系统的WiFi设置向导模块同时需要配置系统签名以及系统应用标识
