我正在制作持续跟踪用户位置的应用程序，到目前为止，我已经能够成功接收其位置更改的坐标，但是如果他重新启动手机，那么如果没有用户再次打开应用程序，我将无法启动我的服务.

确保您拥有 AndroidManifest 文件中的权限：

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

将此更改为：

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

RECEIVE_BOOT_COMPLETED：广播动作：在系统完成启动后广播一次。它可用于执行特定于应用程序的初始化，例如安装警报。您必须拥有 RECEIVE_BOOT_COMPLETED 权限才能接收此广播。
