推荐答案请确保u必须在AndroidManifest文件的权限:
Make Sure u have the permission in AndroidManifest File :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
更改为:
@Override public void onReceive(Context context, Intent intent) { Intent serviceIntent = new Intent(context,BackgroundService.class); startService(serviceIntent); }更多推荐
