实现重启App的功能

自杀式服务重启app完整代码

/**
 * 此工具类用来重启APP，只是单纯的重启，不做任何处理。

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);
    }
}
/***
 * 该服务只用来让APP重启，生命周期也仅仅是只是重启APP。重启完即自我杀死
 */
public class killSelfService extends Service {
    /**关闭应用后多久重新启动*/
    private static  long stopDelayed=2000;
    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",2000);
        PackageName=intent.getStringExtra("PackageName");
        handler.postDelayed(（）->{
                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;
    }
}

最后别忘了，在AndroidManifest.xml文件中去注册Service哦

<service
android:name=".restart_app.killSelfService"
/>
