android 服务 重启,Android APP重启的几种方法

项目开发过程中需要实现重启App的功能，常用的可行方案有：

1. 使用 FLAG_ACTIVITY_CLEAR_TOP ：

new Handler().postDelayed(new Runnable() {

@Override

public void run() {

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage(getApplication().getPackageName());

LaunchIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

startActivity(LaunchIntent);

}

}, 100);// 1秒钟后重启应用

2. 使用 AlarmManager ：

Intent intent = getPackageManager()

.getLaunchIntentForPackage(getApplication().getPackageName());

PendingIntent restartIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);

AlarmManager mgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 1000, restartIntent); // 1秒钟后重启应用

System.exit(0);

3.使用Service

开启一个Service，然后自己杀死APP的进程，最后在Service里通过包名来启动一个APP并销毁Service。

(1)RestartAPPTool.java

public class RestartAPPTool {

/**

* 重启整个APP

* @param context

* @param Delayed 延迟多少毫秒

*/

public static void restartAPP(Context context, long Delayed){

/**开启一个新的服务，用来重启本APP*/

Intent intent1=new Intent(context,killSelfService.class);

intent1.putExtra(“PackageName”,context.getPackageName());

intent1.putExtra(“Delayed”,Delayed);

context.startService(intent1);

/**杀死整个进程**/

android.os.Process.killProcess(android.os.Process.myPid());

}

/***重启整个APP*/

public static void restartAPP(Context context){

restartAPP(context,2000);

}

}

(2)killSelfService.java

public class killSelfService extends Service {

/**关闭应用后多久重新启动*/

private static long stopDelayed=50;

private Handler handler;

private String PackageName;

public killSelfService() {

handler=new Handler();

}

@Override

public int onStartCommand(final Intent intent, int flags, int startId) {

stopDelayed=intent.getLongExtra(“Delayed”,50);

PackageName=intent.getStringExtra(“PackageName”);

handler.postDelayed(new Runnable() {

@Override

public void run() {

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage(PackageName);

startActivity(LaunchIntent);

killSelfService.this.stopSelf();

}

},stopDelayed);

return super.onStartCommand(intent, flags, startId);

}

@Override

public IBinder onBind(Intent intent) {

return null;

}

}

(3)需要在AndroidManifest.xml中注册Service

(4)在需要的地方调用即可

RestartAPPTool.restartAPP(getApplicationContext(),100);
