谷歌API客户端BUG，发送地点 [英] Google API client bug, sending locations
问题描述
我要创造我送每隔几秒钟消息给GCM。但一段时间后，我想再次删除locationupdates。对于数据发送到GCM的intentservice我使用的PendingIntent。现在每次和它发生了很多我得到这个错误：
I want to create that I send every few seconds a message to GCM. But after some time I want to remove the locationupdates again. For sending the data to the intentservice of gcm I use a pendingintent. Now every time and it happens a lot I get this error :
产生的原因：
java.lang.IllegalStateException: GoogleApiClient is not connected yet.

这是我的code：
public class LocationUpdate extends Service implements GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "DRIVER";
private SharedPreferences pref;
private String driverId;
private GoogleApiClient mGoogleApiClient;
private LocationRequest mLocationRequest;
private Intent mGcmIntentService;
private PendingIntent mPendingIntent;
@Override
public IBinder onBind(Intent arg0) {
return null;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
boolean stopService = false;
if (intent != null)
stopService = intent.getBooleanExtra("stopservice", false);
if (stopService)
stopLocationUpdates();
return START_STICKY;
}
@Override
public void onCreate() {
Log.e(TAG, "onCreate");
pref = getSharedPreferences("driver_app", MODE_PRIVATE);
driverId = pref.getString("driver_id", "");
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
}
@Override
public void onDestroy() {
Log.e(TAG, "onDestroy");
super.onDestroy();
}
public void stopLocationUpdates() {
if(!mGoogleApiClient.isConnected()){
mGoogleApiClient.connect();
}
mGcmIntentService = new Intent(this,SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mPendingIntent);
if (mGoogleApiClient.isConnected())
mGoogleApiClient.disconnect();
}
@Override
public void onConnectionFailed(ConnectionResult arg0) {
// TODO Auto-generated method stub
}
@Override
public void onConnected(Bundle arg0) {
// TODO Auto-generated method stub
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setInterval(30000);
startLocationUpdates();
}
private void startLocationUpdates() {
mGcmIntentService = new Intent(this,SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, mPendingIntent);
}
@Override
public void onConnectionSuspended(int arg0) {
// TODO Auto-generated method stub
}
}
任何人知道如何解决这个错误？或如何解决呢？我在网上搜索上，但不能发现任何东西。
Anyone know how to solve this bug? Or how to fix it? I searched on the internet but can't find anything.
推荐答案
的问题是，在你的 stopLocationUpdates（）方法，你是不是在等待该API连你打电话之前 removeLocationUpdates（）。
The problem is that in your stopLocationUpdates() method, you are not waiting for the API to be connected before you call removeLocationUpdates().
一个简单的方法来解决，这将是设置一个布尔标志，当你需要删除位置的回调，但API未连接。
One simple way to fix this would be to set a boolean flag when you need to remove location callbacks, but the API is not connected.
添加一个成员变量：
private boolean isRemoving = false;
然后修改逻辑，这样它等待API来注销的位置回调之前连接。
Then modify the logic so that it waits for the API to connect before unregistering for location callbacks.
在 stopLocationUpdates（）方法：
public void stopLocationUpdates() {
if(!mGoogleApiClient.isConnected()){
isRemoving = true; //added
mGoogleApiClient.connect();
}
else {
mGcmIntentService = new Intent(this, SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, mPendingIntent);
if (mGoogleApiClient.isConnected())
mGoogleApiClient.disconnect();
}
}
在 onConnected（）回调：
@Override
public void onConnected(Bundle arg0) {
if (isRemoving){
stopLocationUpdates();
}
else {
// TODO Auto-generated method stub
mLocationRequest = LocationRequest.create();
mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
mLocationRequest.setInterval(30000);
startLocationUpdates();
}
}
您也想设置标志返回假的 startLocationUpdates（）：
You would also want to set the flag back to false in startLocationUpdates():
private void startLocationUpdates() {
isRemoving = false; //added
mGcmIntentService = new Intent(this,SendDataIntentService.class);
mGcmIntentService.putExtra("ID", "FusedLocation");
mPendingIntent = PendingIntent.getService(this, 0, mGcmIntentService, PendingIntent.FLAG_CANCEL_CURRENT);
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, mPendingIntent);
}
另外在的onCreate（）：
@Override
public void onCreate() {
Log.e(TAG, "onCreate");
isRemoving = false; //added
pref = getSharedPreferences("driver_app", MODE_PRIVATE);
driverId = pref.getString("driver_id", "");
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
}
编辑：要重新启动的位置回调后，他们已经previously取消，您可以使用 onStartCommand（）法
修改 onStartCommand（），使其既可以停止和启动位置更新：
Modify onStartCommand() so that it can both stop and start location updates:
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e(TAG, "onStartCommand");
super.onStartCommand(intent, flags, startId);
boolean stopService = false;
if (intent != null) {
stopService = intent.getBooleanExtra("stopservice", false);
}
if (stopService) {
stopLocationUpdates();
}
else{
isRemoving = false;
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).build();
mGoogleApiClient.connect();
}
return START_STICKY;
}
然后，为了重新启动位置更新，你会叫 startService（）与有意向 stopservice 设置为false：
Then, in order to re-start location updates, you would call startService() with an Intent that has stopservice set to false:
Intent i = new Intent(this, LocationUpdate.class);
i.putExtra("stopservice", false);
startService(i);
