Question

我实际上正在开发一个允许父母跟踪他的孩子的Android应用程序。我面临的问题是GPS位置需要每N秒执行一次，但每当我强行关闭应用程序，或重启移动设备时服务都不会重启。

这是我的LocationService：

public class LocationService extends Service
{
    private LocationListener listener;
    private LocationManager manager;

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
        Toast.makeText(this, "Service.onCreate()", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onDestroy()
    {
        super.onDestroy();
        Toast.makeText(this, "Service.destroy()", Toast.LENGTH_LONG).show();
        if(this.manager != null)
            //noinspection MissingPermission
            this.manager.removeUpdates(this.listener);
    }

    @Override
    public int onStartCommand(Intent intent, int flag, int startId)
    {
        super.onStartCommand(intent, flag, startId);

        //Here end the code to execute
        Toast.makeText(this, "Service.onStartCommand()",Toast.LENGTH_LONG).show();

        this.listener = new LocationListener() {
            @Override
            public void onLocationChanged(Location location) {
                Log.e("started", "service running");
                play();
                Toast.makeText(LocationService.this, location.getLongitude() + " " + location.getLatitude(), Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onStatusChanged(String s, int i, Bundle bundle) {

            }

            @Override
            public void onProviderEnabled(String s) {

            }

            @Override
            public void onProviderDisabled(String s) {
                Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
            }
        };

        this.manager = (LocationManager)getApplicationContext().getSystemService(Context.LOCATION_SERVICE);

        //noinspection MissingPermission
        this.manager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 3000,0, this.listener);

        return START_NOT_STICKY;
    }

    @Override
    public boolean onUnbind(Intent intent)
    {
        // TODO Auto-generated method stub
        Toast.makeText(this, "Service.onUnbind()", Toast.LENGTH_LONG).show();
        return super.onUnbind(intent);
    }
}

我的广播接收器：

public class BootIntentReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {
        Intent serviceIntent = new Intent(context, LocationService.class);
        serviceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startService(serviceIntent);
    }
}

我的Manifest.xml：

<receiver android:name=".activity.service.BootIntentReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>
<service
    android:name=".activity.service.LocationService"
    android:exported="false" />

启动权限：

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

每当我启动设备时都没有任何反应：/

感谢您的帮助！

您是否尝试在清单中使用完全限定的服务名称？

e.g。如果服务在包com.package.activity.service中，请使用<receiver android:name="com.package.activity.service.BootIntentReceiver">而不是<receiver android:name=".activity.service.BootIntentReceiver">

在你的BootIntentReceiver中添加日志或Toast，只是为了加倍确定

服务重新启动强制关闭并重启Android
