如何重新启动收听BOOT_COMPLETED的应用程序

Question

我的应用程序收听BOOT_COMPLETED以启动。

<receiver android:name=".BootReceiver"> 
    <intent-filter> 
    <action android:name="android.intent.action.BOOT_COMPLETED" />   
</receiver> 

但如果我的应用程序崩溃，我怎么能得到它的自动重启？

BOOT_COMPLETED不是一个粘性的意图。

得到你的问题的答案很简单。在这种情况下，你需要使用Thread.setDefaultUncaughtExceptionHandler（）。它会在情况uncaughtException（）始终输入您的应用程序crashed.For Check Full Tutorial Here

public class YourApplication extends Application { 

    private static Context mContext; 

    public static YourApplication instace; 

    @Override 
    public void onCreate() { 
     super.onCreate(); 
     mContext = getApplicationContext(); 
     instace = this; 
    } 

    @Override 
    public Context getApplicationContext() { 
     return super.getApplicationContext(); 
    } 

    public static YourApplication getIntance() { 
     return instace; 
    } 
}

      PendingIntent pendingIntent = PendingIntent.getActivity(
        YourApplication.getInstance().getBaseContext(), 0, intent, intent.getFlags()); 

         //Following code will restart your application after 2 seconds 
      AlarmManager mgr = (AlarmManager) YourApplication.getInstance().getBaseContext()

      System.exit(2); 

     } catch (IOException e) {
