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入口Activity类名

获得获得第三方应用的包名入口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.apk 2.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.xml 1.使用apktool反编译app:apktool.bat d es3.apk E:\apk\es 2.打开AndroidManifest.xml manifest节点的package属性值是应用的包名:<manifest package=”com.estrongs.android.pop”> 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:xxx@abc.com");  
    Intent it = newIntent(Intent.ACTION_SENDTO, uri);  
    startActivity(it);  

    Intent it = new Intent(Intent.ACTION_SEND);     
    it.putExtra(Intent.EXTRA_EMAIL,"me@abc.com");     
    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={"me@abc.com"};       
    String[]ccs={"you@abc.com"};       
    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

    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);

    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

参考:

  1. 查看Android应用包名package和入口activity名称
  2. Android之调用其他程序
  3. Android打开第三方Application的Launch Activity
