打开第三方应用

一、打开第三方应用 
方法一

Intent intent=new Intent();  //包名 包名+类名（全路径）  intent.setClassName("com.linxcool", "com.linxcool.PlaneActivity");  startActivity(intent);  

方法二

Intent intent = new Intent();  ComponentName comp = new ComponentName("com.linxcool","com.linxcool.PlaneActivity");  intent.setComponent(comp);  intent.setAction("android.intent.action.MAIN");  intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);  startActivity(intent);

方法三

出自storm的博客。 
这段代码会检测app是否安装，没安装的话会指向商店下载。

public static final String APP_PACKAGE_NAME = "com.*.*";//包名/** * 启动薄荷App * @param context */public static void launchapp(Context context) {    // 判断是否安装过App，否则去市场下载    if (isAppInstalled(context, APP_PACKAGE_NAME)) {        context.startActivity(context.getPackageManager().getLaunchIntentForPackage(APP_PACKAGE_NAME));    } else {        goToMarket(context, APP_PACKAGE_NAME);    }}/** * 检测某个应用是否安装 *  * @param context * @param packageName * @return */public static boolean isAppInstalled(Context context, String packageName) {    try {        context.getPackageManager().getPackageInfo(packageName, 0);        return true;    } catch (NameNotFoundException e) {        return false;    }}/** * 去市场下载页面 */public static void goToMarket(Context context, String packageName) {    Uri uri = Uri.parse("market://details?id=" + packageName);    Intent goToMarket = new Intent(Intent.ACTION_VIEW, uri);    try {        context.startActivity(goToMarket);    } catch (ActivityNotFoundException e) {    }}

调用第三方应用的关键在于获得第三方应用的包名和入口Activity类名。 
获得获得第三方应用的包名和入口Activity类名

使用aapt //aapt是sdk自带的一个工具，在sdk\builds-tools\目录下1.以ES文件浏览器为例，命令行中切换到aapt.exe目录执行：aapt dump badging E:\apk\es3.apk2.运行后的结果中以下两行分别是应用包名package和入口activity名称package: name=’com.estrongs.Android.pop’//在输出比较靠前的位置launchable-activity: name=’com.estrongs.android.pop.view.FileExplorerActivity’注：在android sdk目录搜索可以找到aapt.exe，如果没有可以下载apktool。查看AndroidManifest.xml1.使用apktool反编译app：apktool.bat d es3.apk E:\apk\es2.打开AndroidManifest.xmlmanifest节点的package属性值是应用的包名：查找android.intent.action.MAIN和android.intent.category.LAUNCHER对应的activity，该activity对应的android:name属性既是入口activity名称，如下：    <activity android:theme=”@android:tyle/Theme.NoTitleBar”     android:label=”@string/app_name” android:name=”com.estrongs.android.pop.view.FileExplorerActivity”>    <intent-filter>    <action android:name=”android.intent.action.MAIN” />    <category android:name=”android.intent.category.LAUNCHER” />    </intent-filter>    </activity>

Android.intent.action.MAIN决定应用程序最先启动的Activity，android.intent.category.LAUNCHER决定应用程序是否显示在 
程序列表里。

顺便分享几个应用的包名和入口Activity(用aapt获得的)： 
app package launcher 
微博 com.sina.weibo com.sina.weibo.SplashActivity 
知乎 com.zhihu.android com.zhihu.android.ui.activity.GuideActivity 
薄荷 com.app.one com.app.one.ui.SplashActivity 
二、系统应用

1.从google搜索内容

Intent intent = new Intent();  intent.setAction(Intent.ACTION_WEB_SEARCH);  intent.putExtra(SearchManager.QUERY,"搜索内容")  startActivity(intent);  

2.浏览网页

Uri uri =Uri.parse("http://www.google.com");  Intent it = new Intent(Intent.ACTION_VIEW,uri);  startActivity(it);  

3.显示地图

Uri uri = Uri.parse("geo:38.899533,-77.036476");  Intent it = newIntent(Intent.Action_VIEW,uri);  startActivity(it);  

4.路径规划

Uri uri =Uri.parse("http://maps.google.com/maps?f=dsaddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");  Intent it = newIntent(Intent.ACTION_VIEW,URI);  startActivity(it);  

5.拨打电话

Uri uri =Uri.parse("tel:xxxxxx");  Intent it = new Intent(Intent.ACTION_DIAL,uri);    startActivity(it);  

这个用法有一定的局限性，就是startActivity()一定要在主线程/UI线程，下面介绍另一种方法： 
在Android M 即android 6.0上新增一个打电话的接口 placeCall(Uri address, Bundle extras)，下面是说明，格式我就不整理了

* Requires permission: {@link android.Manifest.permission#CALL_PHONE}//申请权限** Usage example:* <pre>* Uri uri = Uri.fromParts("tel", "12345", null);//Uri 主要是号码* Bundle extras = new Bundle();* extras.putBoolean(TelecomManager.EXTRA_START_CALL_WITH_SPEAKERPHONE, true);//默认开扬声器* telecomManager.placeCall(uri, extras);

6.发短信

//方法1：  Intent it = newIntent(Intent.ACTION_VIEW);     it.putExtra("sms_body", "TheSMS text");     it.setType("vnd.android-dir/mms-sms");     startActivity(it);  //方法2：  Uri uri =Uri.parse("smsto:0800000123");     Intent it = newIntent(Intent.ACTION_SENDTO, uri);     it.putExtra("sms_body", "TheSMS text");     startActivity(it);  //方法三：  String body="this is sms demo";  Intent mmsintent = newIntent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", number, null));  mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY,body);  mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE,true);  mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT,true);  startActivity(mmsintent);  

7.发送彩信

Uri uri =Uri.parse("content://media/external/images/media/23");     Intent it = newIntent(Intent.ACTION_SEND);     it.putExtra("sms_body","some text");     it.putExtra(Intent.EXTRA_STREAM, uri);     it.setType("image/png");     startActivity(it);  StringBuilder sb = new StringBuilder();  sb.append("file://");  sb.append(fd.getAbsoluteFile());  Intent intent = newIntent(Intent.ACTION_SENDTO, Uri.fromParts("mmsto", number, null));  // Below extra datas are all optional.  intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_SUBJECT,subject);  intent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY,body);  intent.putExtra(Messaging.KEY_ACTION_SENDTO_CONTENT_URI,sb.toString());  intent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE,composeMode);  intent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT,exitOnSent);  startActivity(intent);  

8.发送Email

Uri uri =Uri.parse("mailto:[e-mail]");  Intent it = newIntent(Intent.ACTION_SENDTO, uri);  startActivity(it);  Intent it = new Intent(Intent.ACTION_SEND);     it.putExtra(Intent.EXTRA_EMAIL,"[e-mail]");     it.putExtra(Intent.EXTRA_TEXT, "Theemail body text");     it.setType("text/plain");     startActivity(Intent.createChooser(it,"Choose Email Client"));  Intent it=new Intent(Intent.ACTION_SEND);       String[] tos={"[e-mail]"};       String[]ccs={"[e-mail]"};       it.putExtra(Intent.EXTRA_EMAIL, tos);       it.putExtra(Intent.EXTRA_CC, ccs);       it.putExtra(Intent.EXTRA_TEXT, "Theemail body text");       it.putExtra(Intent.EXTRA_SUBJECT, "Theemail subject text");       it.setType("message/rfc822");       startActivity(Intent.createChooser(it,"Choose Email Client"));     Intent it = newIntent(Intent.ACTION_SEND);     it.putExtra(Intent.EXTRA_SUBJECT, "Theemail subject text");      it.putExtra(Intent.EXTRA_STREAM,"file:///sdcard/mysong.mp3");     sendIntent.setType("audio/mp3");     startActivity(Intent.createChooser(it,"Choose Email Client"));

9.播放多媒体

Intent it = new Intent(Intent.ACTION_VIEW);  Uri uri =Uri.parse("file:///sdcard/song.mp3");  it.setDataAndType(uri,"audio/mp3");  startActivity(it);  Uri uri =Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI,"1");     Intent it = new Intent(Intent.ACTION_VIEW,uri);     startActivity(it);  

10.卸载 apk

Uri uri =Uri.fromParts("package", strPackageName, null);     Intent it = newIntent(Intent.ACTION_DELETE, uri);     startActivity(it);  

11.安装 apk

Uri installUri = Uri.fromParts("package","xxx", null);  returnIt = newIntent(Intent.ACTION_PACKAGE_ADDED, installUri);  Intent intent = new Intent(Intent.ACTION_VIEW);  intent.setDataAndType(Uri.parse("file://" + filepath),"application/vnd.android.package-archive");  startActivity(intent);// 安装 

12.打开照相机

//1  Intent intent = new Intent("android.media.action.STILL_IMAGE_CAMERA"); //调用照相机  startActivity(intent);  //2  Intent i = new Intent(Intent.ACTION_CAMERA_BUTTON, null);  this.sendBroadcast(i);  //3  long dateTaken = System.currentTimeMillis();  String name = createName(dateTaken) + ".jpg";  fileName = folder + name;  ContentValues values = new ContentValues();  values.put(Images.Media.TITLE, fileName);  values.put("_data", fileName);  values.put(Images.Media.PICASA_ID, fileName);  values.put(Images.Media.DISPLAY_NAME, fileName);  values.put(Images.Media.DESCRIPTION, fileName);  values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, fileName);  Uri photoUri = getContentResolver().insert(  MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);  Intent inttPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);  startActivityForResult(inttPhoto, 10);  

13.从gallery选取图片

14.打开录音机

Intent mi = new Intent(Media.RECORD_SOUND_ACTION);  startActivity(mi);  

15.显示应用详细列表

Uri uri =Uri.parse("market://details?id=app_id");          Intent it = new Intent(Intent.ACTION_VIEW,uri);          startActivity(it);          //where app_id is the application ID, findthe ID           //by clicking on your application on Markethome           //page, and notice the ID from the addressbar  //发现用package name也可以  //Uri uri =Uri.parse("market://details?id=<packagename>");  

16.寻找应用

Uri uri =Uri.parse("market://search?q=pname:pkg_name");          Intent it = new Intent(Intent.ACTION_VIEW,uri);          startActivity(it);  //where pkg_name is the full package pathfor an application    

17.打开联系人列表

//1             Intent i = new Intent();  i.setAction(Intent.ACTION_GET_CONTENT);  i.setType("vnd.android.cursor.item/phone");  startActivityForResult(i, REQUEST_TEXT);  //2  Uri uri = Uri.parse("content://contacts/people");  Intent it = new Intent(Intent.ACTION_PICK, uri);  startActivityForResult(it, REQUEST_TEXT);  

18.调用系统编辑添加联系人
