我出错了任何帮助都会在重新启动手机时受到高度赞赏我得到了demoapp已经停止我尝试在接收器上烤面包但是烤面包也不会出现在目前

Answer 1

确保您拥有AndroidManifest文件中的权限：

  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

将其更改为：

@Override
public void onReceive(Context context, Intent intent) {
    Intent serviceIntent = new Intent(context,BackgroundService.class);
    startService(serviceIntent);
    }

Answer 2

RECEIVE_BOOT_COMPLETED ：广播操作：系统完成引导后，播放一次。它可用于执行特定于应用程序的初始化，例如安装警报。您必须持有RECEIVE_BOOT_COMPLETED权限才能接收此广播。
