我曾经使用AlarmManager + WakefulBroadcastReceiver + Service来做一些背景代码并获取位置更新。
自奥利奥(Oreo)以来,此方法已被弃用,因此现在我使用AlarmManager + BroadcastReceiver + JobIntentService。
这是清单中JobIntentService的代码:
<service android:name="MyJobIntentService"
android:permission="android.permission.BIND_JOB_SERVICE"/>
我需要位置更新的类MyJobIntentService:
public class MyJobIntentService extends JobIntentService implements
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener,
com.google.android.gms.location.LocationListener {
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
@Override
public void onCreate() {
super.onCreate();
}
//Convenience method for enqueuing work in to this service.
static void enqueueWork(Context context, Intent work) {
enqueueWork(context, clsJobIntentServiceDePosicionamientoPlayServices.class, 123456, work);
}
@Override
protected void onHandleWork(Intent intent) {
// We have received work to do. The system or framework is already holding a wake lock for us at this point, so we can just go.
StartLocating();
}
@Override
public void onDestroy() {
super.onDestroy();
}
void StartLocating(){
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mGoogleApiClient.connect();
}
And the rest of the location functions like onLocationChanged...
该应用程序可以运行(至少在模拟器上可用),但是我担心我做错了,因为在onCreate()之后,它被称为onHandleWork(),然后在onDestroy()之后。
几秒钟后,我开始在onLocationChanged中获取位置更新,但由于出事onDestroy(),我担心出现了问题。这是正确的方法吗?
这是我从BroadcastReceiver创建JobIntentService的方式:
Intent i = new Intent(contexto, MyJobIntentService.class);
MyJobIntentService.enqueueWork(MyContext, i);
最佳答案
JobIntentService不是您想要的,它代替了IntentService。这意味着,当onHandleIntent方法结束时,该服务将被终止。在您的情况下,您需要使用前台服务或使用其他服务。
