Question

我的应用会听取BOOT_COMPLETED开始。

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

但是如果我的应用崩溃了，我怎么能将它变为自动重启？

BOOT_COMPLETED不是一个棘手的意图。

要获得您的问题的答案非常简单。在这种情况下，您需要使用Thread.setDefaultUncaughtExceptionHandler（）。如果您的应用程序崩溃，它将始终输入uncaughtException（）。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;
    }
}

    @Override

        try {

            Intent intent = new Intent(activity, RelaunchActivity.class);

            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                    | Intent.FLAG_ACTIVITY_CLEAR_TASK
                    | Intent.FLAG_ACTIVITY_NEW_TASK);

            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()
                    .getSystemService(Context.ALARM_SERVICE);
            mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 1000,
                    pendingIntent);

                        //This will finish your activity manually
            activity.finish();

                        //This will stop your application and take out from it.
            System.exit(2);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
