I had a good working app for GetGeoLocation for API level 23( Using checkSelfPermission). But, then i had to make it compatible with API level 21. So, checkSelfPermission didn't work as it was introduced in API Level 23.
So, i changed the code to accomodate this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CheckForCoarseLocationPermission();
}
private void CheckForCoarseLocationPermission()
{
if (android.os.Build.VERSION.SDK_INT >= 23)
{
// ANDROID 6.0 AND UP!
boolean accessCoarseLocationAllowed = false;
try
{
// Invoke checkSelfPermission method from Android 6 (API 23 and UP)
java.lang.reflect.Method methodCheckPermission = Activity.class.getMethod("checkSelfPermission", java.lang.String.class);
Object resultObj = methodCheckPermission.invoke(this, Manifest.permission.ACCESS_COARSE_LOCATION);
int result = Integer.parseInt(resultObj.toString());
if (result == PackageManager.PERMISSION_GRANTED)
{
accessCoarseLocationAllowed = true;
}
}
catch (Exception ex)
{
}
if (accessCoarseLocationAllowed)
{
Log.v("TAG","Granted");
LocationManager locationManager= (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,new LocationListener());//ERROR Happening Here!!!!!!!!!!!
}
try
{
// We have to invoke the method "void requestPermissions (Activity activity, String[] permissions, int requestCode) "
// from android 6
java.lang.reflect.Method methodRequestPermission = Activity.class.getMethod("requestPermissions", java.lang.String[].class, int.class);
methodRequestPermission.invoke(this, new String[]
{
Manifest.permission.ACCESS_FINE_LOCATION
}, 0x12345);
}
catch (Exception ex)
{
}
}
}
Now, the LocationManager.requestLocationUpdate is giving an error
Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with checkPermission
) or explicitly handle a potential SecurityException
less
How to tackle it, if i want to use LocationManager and CheckPermission for API level >=21.
Kindly, help.
Try this
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) { // coarse permission is granted
// Todo
} else { // permission is not granted, request for permission
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_COARSE_LOCATION)) { // show some info to user why you want this permission
Toast.makeText(this, "Allow Location Permission to use this functionality.", Toast.LENGTH_SHORT).show();
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 123 /*LOCATION_PERMISSION_REQUEST_CODE*/);
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 123 /*LOCATION_PERMISSION_REQUEST_CODE*/);
}
}
Note:- you must have the following permission in android manifest
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
