I am trying to make an application that sends location updates of a user after every five minutes. I suppose my code is working just fine but i get an error regarding the permissions that are being used by the application. I am pretty sure that i have added the permissions in the manifest file. Can someone tell me what's wrong? Here is my code.
MainActivity.java
LocationManager locationManager ;
String provider;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Getting LocationManager object
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
// Creating an empty criteria object
Criteria criteria = new Criteria();
// Getting the name of the provider that meets the criteria
provider = locationManager.getBestProvider(criteria, false);
if(provider!=null && !provider.equals("")){
// Get the location from the given provider
Location location = locationManager.getLastKnownLocation(provider);
locationManager.requestLocationUpdates(provider,5*60*1000,0,this);
if(location!=null)
onLocationChanged(location);
else
Toast.makeText(getBaseContext(), "Location can't be retrieved", Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getBaseContext(), "No Provider Found", Toast.LENGTH_SHORT).show();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public void onLocationChanged(Location location) {
// Getting reference to TextView tv_longitude
TextView tvLongitude = (TextView)findViewById(R.id.tv_longitude);
// Getting reference to TextView tv_latitude
TextView tvLatitude = (TextView)findViewById(R.id.tv_latitude);
// Setting Current Longitude
tvLongitude.setText("Longitude:" + location.getLongitude());
// Setting Current Latitude
tvLatitude.setText("Latitude:" + location.getLatitude() );
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
I am getting an error as Call requires permission which may be rejected by user in these lines-
Location location = locationManager.getLastKnownLocation(provider);
locationManager.requestLocationUpdates(provider,5*60*1000,0,this);
My AndroidManifest is like this
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Which SDK do you use? If you use Marshmallow, then you need to check that the user has granted permission for every location call.
Take a look Here.
You should do something like this:
if (ContextCompat.checkSelfPermission( this,android.Manifest.permission.ACCESS_COARSE_LOCATION ) != PackageManager.PERMISSION_GRANTED )
{
ActivityCompat.requestPermissions(
this,
new String [] { android.Manifest.permission.ACCESS_COARSE_LOCATION },
LocationService.MY_PERMISSION_ACCESS_COURSE_LOCATION
);
}
request permission if you dont have it already.
check the link above for more info.
