Android Activity 不会停止服务和位置更新

【中文标题】Android Activity 不会停止服务和位置更新【英文标题】：Android Activity doesn't stop service and location updates 【发布时间】：2020-01-28 08:49:38 【问题描述】：我正在使用 google api 客户端跟踪 MainActivity 中用户的当前位置并更新当前位置的标记。在服务中，我跟踪用户的当前位置并将其存储到 firebase 实时数据库。
在MainActivity 中，我使用按钮停止服务，方法是断开 api 客户端以及停止服务。
根据类似的问题，我已经在我的服务中实现了 ondestroy。仍然在 api 客户端断开连接后，服务正在运行并将位置存储到 firebase。
如何停止此服务？
地图活动：
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
process = (Button)findViewById(R.id.buttonMaps);
stoptrek = (Button) findViewById(R.id.buttonService);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
checkLocationPermission();
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
process.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
Toast.makeText(MapsActivity.this,"processing...",Toast.LENGTH_SHORT).show();
Intent i = new Intent(MapsActivity.this,MapsActivity2.class);
MapsActivity.this.startActivity(i);
finishActivity(1);
);
stoptrek.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
stopTrackerService();
stopService(new Intent(MapsActivity.this, TrackingService.class));
Toast.makeText(MapsActivity.this, "GPS tracking disabled", Toast.LENGTH_SHORT).show();
);
public void onMapReady(GoogleMap googleMap)
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED)
buildGoogleApiClient();
mMap.setMyLocationEnabled(true);
startTrackerService();
else
buildGoogleApiClient();
mMap.setMyLocationEnabled(true);
startTrackerService();
public void stopTrackerService()
if(mGoogleApiClient.isConnected())
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, (com.google.android.gms.location.LocationListener) MapsActivity.this);
mGoogleApiClient.disconnect();
Toast.makeText(MapsActivity.this,"Disconnected api client",Toast.LENGTH_SHORT).show();
else
Toast.makeText(MapsActivity.this,"api client is already disconnected",Toast.LENGTH_SHORT).show();
服务：
公共类 TrackingService 扩展服务
FusedLocationProviderClient client;
private static final String TAG = TrackingService.class.getSimpleName();
public TrackingService()
@Override
public IBinder onBind(Intent intent)
return null;
@Override
public void onCreate()
super.onCreate();
buildNotification();
loginToFirebase();
@Override
public void onDestroy()
stopSelf();
//Create the persistent notification//
private void buildNotification()
String stop = "stop";
// Create the persistent notification
Notification.Builder builder = new Notification.Builder(this)
.setContentTitle(getString(R.string.app_name))
.setContentText(getString(R.string.tracking_enabled_notif))
.setOngoing(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN)
startForeground(1, builder.build());
private void loginToFirebase()
String email = "xyz@sdl.com";//getString(R.string.test_email);
String password = "xyz123";//getString(R.string.test_password);
FirebaseAuth.getInstance().signInWithEmailAndPassword(
email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>()
@Override
public void onComplete(Task<AuthResult> task)
if (task.isSuccessful())
requestLocationUpdates();
else
Log.d(TAG, "Firebase authentication failed");
);
private void requestLocationUpdates()
LocationRequest request = new LocationRequest();
request.setInterval(5000);
request.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
client = LocationServices.getFusedLocationProviderClient(this);
final String path = "location";
int permission = ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION);
if (permission == PackageManager.PERMISSION_GRANTED)
client.requestLocationUpdates(request, new LocationCallback()
@Override
public void onLocationResult(LocationResult locationResult)
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
String uid = user.getUid();
DatabaseReference ref = FirebaseDatabase.getInstance().getReference();
Location location = locationResult.getLastLocation();
if (location != null)
Toast.makeText(TrackingService.this,"recently add to DB",Toast.LENGTH_SHORT).show();
ref.child(uid).child(path).push().setValue(location);
, null);
我有地图活动，我与 googleapiclient 断开连接，但即使在停止位置更新和服务之后，位置也会被推送到数据库中。
请告诉我如何完全停止服务。 谢谢
【问题讨论】：
因为你没有停止后台服务 我该如何阻止它？我在服务运行时显示通知，当服务停止时，通知不存在。但我可以看到值被推入数据库。 等我贴出停止服务的代码 是的，当然！谢谢。 看看我的回答。 【参考方案1】：此方法检查服务是否正在运行。如果服务正在运行，则返回 true，否则返回 false。
检查运行服务：
public static boolean isServiceRunning(Context context, Class<?> cls)
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
if (activityManager != null)
for (ActivityManager.RunningServiceInfo runningServiceInfo : activityManager.getRunningServices(Integer.MAX_VALUE))
if (cls.getName().equals(runningServiceInfo.service.getClassName()))
return true;
return false;
停止运行服务：
ActivityStackManager.getInstance().stopLocationService(TrackingService.this);
工作原理：
if (isServiceRunning(this, TrackingService.class))
ActivityStackManager.getInstance().stopLocationService(TrackingService.this);
注意：在您想断开位置更新的位置也停止服务，我可以看到您正在断开位置更新 stopTrackerService() 方法
例如：
public void stopTrackerService()
if (isServiceRunning(this, TrackingService.class))
ActivityStackManager.getInstance().stopLocationService(TrackingService.this);
if(mGoogleApiClient.isConnected())
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, (com.google.android.gms.location.LocationListener) MapsActivity.this);
mGoogleApiClient.disconnect();
Toast.makeText(MapsActivity.this,"Disconnected api client",Toast.LENGTH_SHORT).show();
else
Toast.makeText(MapsActivity.this,"api client is already disconnected",Toast.LENGTH_SHORT).show();
ActivityStackManager
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import android.util.Log;
public class ActivityStackManager
private static final ActivityStackManager mActivityStack = new ActivityStackManager();
private ActivityStackManager()
public static ActivityStackManager getInstance()
return mActivityStack;
public void stopLocationService(Context context)
if (isServiceRunning(context, TrackingService.class))
context.stopService(new Intent(context, LocationService.class));
Log.e("StackManager", "TrackingServiceStop");
public void startLocationService(Context context)
Intent serviceIntent = new Intent(context, TrackingService.class);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
context.startForegroundService(serviceIntent);
else
context.startService(serviceIntent);
【讨论】：
如果有帮助请告诉我。 是的，实现它。 我有 android studio v 对不起，我忘记添加那个类了，这是我为服务而写的单例类。 请通过 ActivityStackManager 中的 isServiceRunning...我刚刚从我的项目中提取了一段代码，这就是为什么它丢失了一些代码以上是关于Android Activity 不会停止服务和位置更新的主要内容，如果未能解决你的问题，请参考以下文章
