I am using Fused Location to get current location of my device, but the code that I have implemented always return NULL. I have double checked that my device Location is ON and is set to High Accuracy Mode. Please tell what is problem in my code?
My Code:
import android.app.Activity;
import android.content.Context;
import android.content.IntentSender;
import android.content.pm.PackageManager;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.content.ContextCompat;
import android.util.Log;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.PendingResult;

import com.google.android.gms.location.LocationSettingsRequest;
import com.google.android.gms.location.LocationSettingsResult;
import com.google.android.gms.location.LocationSettingsStatusCodes;
public class FusedLocationTest implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, LocationListener {
private static Location mLastLocation;
private static GoogleApiClient mGoogleApiClient;
private static Context context;
public Location getCurrentLocation(Context context) {
this.context = context;
buildGoogleApiClient();
mGoogleApiClient.connect();
if ((ContextCompat.checkSelfPermission(context, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) && (ContextCompat.checkSelfPermission(context, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)) {
}
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
return mLastLocation;
}
/*connect to fused location provider*/
synchronized void buildGoogleApiClient() {
mGoogleApiClient = new GoogleApiClient.Builder(context)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
#Override
public void onConnected(Bundle bundle) {
}
#Override
public void onLocationChanged(Location location) {
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
buildGoogleApiClient();
}
#Override
public void onConnectionSuspended(int i) {
}
}
Call on button Click:
#Override
public void onClick(View v) {
Location l = new FusedLocationTest().getCurrentLocation(this);
if(l!=null)
Toast.makeText(this,l.getLatitude()+", "+l.getLongitude(), Toast.LENGTH_SHORT).show();
else
Toast.makeText(this,"NULL LOCATION", Toast.LENGTH_LONG).show();
}
Add this code to your onConnected, thats where it would get Last Known Location.
private static Location mLastLocation;
private static GoogleApiClient mGoogleApiClient;
private static Context context;
// added
private LocationRequest mLocationRequest;
private Double latitude;
private Double longitude;
private String TAG = ""; // set your TAG
#Override
public void onConnected(Bundle bundle) {
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
startLocationUpdates();
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if(mLastLocation == null){
startLocationUpdates();
}
if (mLastLocation != null) {
latitude = mLocation.getLatitude();
longitude = mLocation.getLongitude();
// set your tag
Log.d(TAG, String.valueOf(latitude));
Log.d(TAG, String.valueOf(longitude));
} else {
Toast.makeText(context, "Location not Detected, Did you turn off your location?", Toast.LENGTH_SHORT).show();
}
}
protected void startLocationUpdates() {
// Create the location request
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(30 * 1000)
.setFastestInterval(5 * 1000);
// Request location updates
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
}
And remove synchronized from your method, Just make it public. Something like this below:
public void buildGoogleApiClient() { }
The mGoogleApiClient.connect() function is asynchronous. You have to wait until onConnected until the last location is available. There is a clear example of this in the documentation.

I am creating an app like Uber but I have ran into a problem after I got an error suddenly and the app crashed. I tried out many ways in order to get ride of this error but it didn't work. All the answers to the similar questions that I could find on Stackoverflow were that this problem is caused due to FirebaseDatabase.getInstance().setPersistenceEnabled(true) and I had to delete this code of line as this is a bug with Firebase that is yet to be solved. But this didn't solve my problem as i didn't have any such code. That's why i thought this is a question which is not on stackoverflow and asked the question. This is my Java Code

You can add the following line in AndroidManifest.xml:
<uses-library android:name="org.apache.http.legacy" android:required="false"/>
Use com.firebase:geofire-android:2.1.1. Maybe it's a version problem. This solved it for me.
I had a similar problem, and it was resolved by running it in an emulator with Google Play enabled and updated. Basically create a new Virtual Device that has Google Play (not just Google API).
See This Question for details.
I was requesting the location updates with the help of
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient,
locationRequest, locationListener);
But As I tried to mention this on a swtich onClickListener , it crashed. However there was no error thrown Android Studio itself.
I already have added permission to request Fused Location, coarse Location and Internet as part of this function. I even tried to connect the google Api client before requesting the Updated
Like.,
if(googleApiClient.isConnected){
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient,
locationRequest, locationListener);
}else{
buildGoogleApiClient();
}
But I could not get the error resolved.
removing the location request with Fused Location Provider Api is also causing the app to crash.
My Manifest file have codes as given below. As you can see i already have requested the permissions requred
My XML File is as

You have requested location updates with the help of locationListener which you have not initialized. You can solve the problem either by initializing a location listener or by changing locationListener to this in the given statement of your code.
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, locationListener);
to:
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, locationRequest, this);
Implementation of fused location service has changed, you can do that without the GoogleApiClient. You can try like this,
Add required location library to build.grade
implementation 'com.google.android.gms:play-services-location:15.0.0'
Add required permissions to manifest
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Looks like you are using your mGoogleApiClient before it is initialized.
The initialization of
private Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
should be done after you have initialized mGoogleApiClient in onCreate.
So change to
private Location mLastLocation;
and add
mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
in your onCreate after buildGoogleApiClient();
I also got the same problem. But it got solved by doing these following steps:
Add the following meta-data tag in the andriod manifest file, note google_play_services_version is given a value of 8487000
<activity android:name=".MainActivity" android:label="#string/app_name" >
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version"/>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
In app level build.gradle , add the following line in dependencies:
compile 'com.google.android.gms:play-services-location:8.4.0'
So i have this code:
package com.entu.bocterapp;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;

} else {

//TODO:
}
}

} else return null;
}
private synchronized void buildGoogleApiClient() {

}
private boolean checkIfGooglePlayServicesAreAvailable() {
int errorCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(mContext);
if (errorCode != ConnectionResult.SUCCESS) {
GooglePlayServicesUtil.getErrorDialog(errorCode, (RecentSightings) mContext, 0).show();
return false;
}
return true;
}
#Override
public void onConnected(Bundle bundle) {
Location location = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
if (location != null) {
mLastLocation = location;
Toast.makeText(mContext, location.getLongitude() + " , " + location.getLatitude() + " : " + location.getAccuracy(), Toast.LENGTH_LONG).show();
}
}
#Override
public void onConnectionSuspended(int i) {
Toast.makeText(mContext, "suspended", Toast.LENGTH_LONG).show();
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
}
}
I am trying to get location in this class, but onConnected() never gets called(i waited for 1-2 minutes). I went with the debugger, it says google play services are available.
Does anyone know what i'm doing wrong? I'm stuck here for hours, reading everything, and can't get it to work.
Cheers!
You must call
mGoogleApiClient.connect();
try this:
#Override
protected void onStart() {
if(mGoogleApiClient!=null){
mGoogleApiClient.connect();
}
super.onStart();
}
#Override
protected void onStop() {
if(mGoogleApiClient!=null){
if(mGoogleApiClient.isConnected()){
mGoogleApiClient.disconnect();
}
}
super.onStop();
}
I got the same problem just updated my grade version :10.0.1' to
compile 'com.google.android.gms:play-services-location:10.2.1'
it works.
