Hello I am building an app I would like to access the location of the mobile phone. However it seems that I can not grant the access fine location permission so my app doesn't function in Android M cellphone which I am testing. Here is a part of my code:
public class LocationMainActivity extends AppCompatActivity {
private ListView listView;
private static final String EXTERNAL_PERMISSIONS[] = new String[]{
Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.INTERNET};
private static final int EXTERNAL_CODE=1;
private boolean perm;
private Cursor cursor;
private DatabaseAdapt dbAdapt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_location_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar4);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
listView = (ListView)findViewById(R.id.locationContainer);
dbAdapt = new DatabaseAdapt(this);
dbAdapt.open();
cursor =dbAdapt.loadLocationTitles();
String [] from = new String[]{DatabaseAdapt.LOCATION_TITLE};
int [] to = new int[] {android.R.id.text1};
CursorAdapter cursorAdapter = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_1,cursor,
from,to,0);
listView.setAdapter(cursorAdapter);
}
public void onDestroy(){
super.onDestroy();
cursor.close();
dbAdapt.close();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main,menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id==R.id.add_button);{
askForPerm();
if(perm){
Intent intent = new Intent(LocationMainActivity.this,LocationSecondActivity.class);
startActivity(intent);
}
else {
askForPerm();
}
}
return super.onOptionsItemSelected(item);
}
private void askForPerm () {
// if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int w = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
int r = ContextCompat.checkSelfPermission(this, Manifest.permission.INTERNET);
if (w != PackageManager.PERMISSION_GRANTED && r != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, EXTERNAL_PERMISSIONS, EXTERNAL_CODE);
} else {
Toast.makeText(this, "Permissions already granted", Toast.LENGTH_SHORT).show();
perm=true;
}
}
@Override
public void onRequestPermissionsResult(int requestCode,String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode){
case EXTERNAL_CODE:
if(ActivityCompat.checkSelfPermission(this,permissions[0])==PackageManager.PERMISSION_GRANTED)
{
perm=true;
}
else {
Toast.makeText(this,"Permissions denied",Toast.LENGTH_LONG).show();
perm=false;
}
break;
}
}
}
In this activity I ask for the permissions and only then I can add a new location. The app moves to the next activity regularly, the permissions granted toast is shown even I install the app for the first time which seems a little weird. I use the same code to request the Write External and camera permissions in another feature of the app and it is working fine.
I have also included the code of my second activity where I would like to obtain the location coordinates
private EditText editTitleLocation, addressText, latText,longText;
private Button saveLocationButton, deleteLocationButton, navigateButton,findLocationButton;
private static final int UPDATE_TIME = 15000;
private static final int FASTER_UPDATE_TIME = 10000;
private GoogleApiClient myGoogleApi;
private Location location;
private LocationRequest myLocationRequest;
private static final int CHECK_CODE=1;
private double longitude,latitude;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_location_second);
ActionBar actionBar = getSupportActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowHomeEnabled(true);
initializeViews();
buildGoogleApi();
}
private void initializeViews(){
editTitleLocation = (EditText)findViewById(R.id.editTitleLocation);
addressText = (EditText)findViewById(R.id.addressText);
latText = (EditText)findViewById(R.id.latitudeText);
longText=(EditText)findViewById(R.id.longitudeText);
saveLocationButton = (Button)findViewById(R.id.saveLocation);
deleteLocationButton = (Button)findViewById(R.id.deleteLocation);
findLocationButton = (Button)findViewById(R.id.findLocation);
navigateButton= (Button)findViewById(R.id.navigateLocation);
saveLocationButton.setOnClickListener(this);
deleteLocationButton.setOnClickListener(this);
findLocationButton.setOnClickListener(this);
navigateButton.setOnClickListener(this);
}
public void onStart(){
super.onStart();
if(myGoogleApi!=null){
myGoogleApi.connect();
}
}
public void onPause(){
super.onPause();
if(myGoogleApi!=null)
LocationServices.FusedLocationApi.removeLocationUpdates(myGoogleApi,LocationSecondActivity.this);
}
public void onStop(){
super.onStop();
myGoogleApi.disconnect();
}
private synchronized void buildGoogleApi(){
myGoogleApi = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API).build();
}
private void createRequest (){
myLocationRequest = new LocationRequest();
myLocationRequest.setInterval(UPDATE_TIME)
.setFastestInterval(FASTER_UPDATE_TIME)
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(myLocationRequest);
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(myGoogleApi,builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
switch (status.getStatusCode()){
case LocationSettingsStatusCodes.SUCCESS:
retrieveLocation();
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
try{
status.startResolutionForResult(LocationSecondActivity.this,CHECK_CODE);
}catch (IntentSender.SendIntentException e){
e.printStackTrace();
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
Toast.makeText(LocationSecondActivity.this,"Settings Change Unavailable",Toast.LENGTH_SHORT).show();
break;
}
}
});
}
private void retrieveLocation(){
try {
location = LocationServices.FusedLocationApi.getLastLocation(myGoogleApi);
}catch (SecurityException ex){
ex.printStackTrace();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode){
case CHECK_CODE:
switch (requestCode){
case Activity.RESULT_OK:
retrieveLocation();
break;
case Activity.RESULT_CANCELED:
break;
}
break;
}
}
@Override
public void onConnected(Bundle bundle) {
createRequest();
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Toast.makeText(this,"Google Api can not connect",Toast.LENGTH_LONG).show();
}
@Override
public void onLocationChanged(Location location) {
this.location=location;
longitude=location.getLongitude();
latitude=location.getLatitude();
}
@Override
public void onClick(View v) {
int id = v.getId();
switch (id){
case R.id.saveLocation:
break;
case R.id.deleteLocation:
break;
case R.id.navigateLocation:
break;
case R.id.findLocation:
if(location!=null){
latitude = location.getLatitude();
Log.e("MALAKIS",String.valueOf(latitude));
longitude=location.getLongitude();
latText.setText(String.valueOf(latitude));
longText.setText(String.valueOf(longitude));
}else {
if(!myGoogleApi.isConnected()){
myGoogleApi.connect();
Log.e("ELSE","fdsfddsd");
}
try {
LocationServices.FusedLocationApi.requestLocationUpdates(myGoogleApi, myLocationRequest, this);
}catch (SecurityException ex){
ex.printStackTrace();
}
}
break;
}
}
Here the location is object is null and the security location is triggered pointing that I dont have the fine location permission. So please can someone point me to the right direction? Do I have do ask again for permissions in the second activity?
The log is showing this below:
W/System.err: java.lang.SecurityException: Client must have
ACCESS_FINE_LOCATION permission to request PRIORITY_HIGH_ACCURACY
locations.

put following code in your askForPerm () method:-
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
builder.setAlwaysShow(true); //this is the key ingredient
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can initialize location
// requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be fixed by showing the user
// a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way to fix the
// settings so we won't show the dialog.
break;
}
}
});
Try this!!It works in my application.
