My App Crashes because of permission denial

I have an issue with my Android App. I am asking for permissions to the user to access the READ_EXTERNAL_STORAGE but the bug "permission denial" still makes my app crash.
I have spent hours on it and I have no clue how to fix it.
Here's my logcat:

From Android Developer Documentation
If your app needs a dangerous permission, you must check whether you have that permission every time you perform an operation that requires that permission. Beginning with Android 6.0 (API level 23), users can revoke permissions from any app at any time, even if the app targets a lower API level.
So you need to request permission like this
#TargetApi(23)
public void enableRunTimePermisstion() {
if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) &&
(getActivity().checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
PackageManager.PERMISSION_GRANTED))
if (getActivity().shouldShowRequestPermissionRationale
(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
Toast.makeText(getActivity(), "Write storage permission is need for app"
, Toast.LENGTH_LONG).show();
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
} else {
requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
Toast.makeText(getActivity(), "request permission"
, Toast.LENGTH_LONG).show();
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == 1) {
if (permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE) &&
grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(context, "Write external storage granted", Toast.LENGTH_LONG).show();
// >> here you call the method that need the permission
}
} else {
Toast.makeText(getActivity(), "Write external permission denied", Toast.LENGTH_SHORT).show();
enableRunTimePermisstion(); // >> When user request the permission we calling the previous method again.
}
}

Runtime permission has actually taken a new shape in the recent times ... like you need to use a fileprovider, provide Uri and the likes but here is a good library that i have used in the recent times. It works well and hassle free. You can check it out on codepath.

Android App doesn't show location

I was looking for the solution to my problem the whole day now, but I couldn't find out. I'm absolutely new to java/android studio/app programming and probably it's just a very small thing that I don't see.
I just want my App to show the current location of the device. Nothing more.
When running the App on the emulator, no error is shown and the App starts.
Then I open the extended controls and push the "SEND"-button in "Location".
Now I would expect my App to show the current location, but nothing happens. The TextViews "textLat", "textLong" and "textAlt" are staying empty.
I have absolutely no Idea what my fault is. I wrote that code with the help of different tutorials. I also tried it on my real device.
I would be very grateful for any help! Thanks alot!
package com.example.findlocation_test2;
import android.Manifest;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.provider.Settings;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
TextView textLat;
TextView textLong;
TextView textAlt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textLat = (TextView) findViewById(R.id.textLat);
textLong = (TextView) findViewById(R.id.textLong);
textAlt = (TextView) findViewById(R.id.textAlt);
LocationManager lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
LocationListener ll = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
if(location != null) {
double dLat = location.getLatitude();
double dLong = location.getLongitude();
double dAlt = location.getAltitude();
textLat.setText(Double.toString(dLat));
textLong.setText(Double.toString(dLong));
textAlt.setText(Double.toString(dAlt));
}
else {
textLat.setText("Fehler");
textLong.setText("Fehler");
textAlt.setText("Fehler");
}
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
#Override
public void onProviderEnabled(String provider) {
Toast.makeText(getBaseContext(), "GPS wurde akiviert",
Toast.LENGTH_SHORT).show();
}
#Override
public void onProviderDisabled(String provider) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
Toast.makeText(getBaseContext(), "GPS wurde deaktiviert",
Toast.LENGTH_SHORT).show();
}
};
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
// ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
// public void onRequestPermissionsResult(int requestCode, String[] permissions,
// int[] grantResults)
// to handle the case where the user grants the permission. See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 0, ll);
}
}
And in the manifest I added the permissions:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.findlocation_test2">
<uses-permission android:name="android.permission.ACCESS_INTERNET"/>

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

</application>
</manifest>

spotify authentication failure

I am following the Spotify tutorial on android sdk beta22-noconnect-2.20b to just get the groundwork on an app that I want to to write and I am having trouble getting my application to authenticate. I am sure that I have signed my app and inserted the correct fingerprint into the "My Applications" tab on spotify. My URI is correct. I am also fairly certain that I followed the tutorial 100% properly. Every time I run the program I get this error.
I/OpenGLRenderer: Initialized EGL, version 1.4

Android LocationListener onLocationChanged() is never called

I'm developing a Android app and I'm still green in this area.
In my app I'm using the FusedLocationApi to get both the last know location and make Location update requests and I got a problem where, even with both Location and WiFi activated on Android Studio emulator and Samsung Galaxy S5, I never got the LocationListener's onLocationChanged() called.

I'v searched a lot this week but I've got no helpful answer yet =s
These are some of the threads I've searched (I don't want to look like a lazy guy, because I'm not, I'm just stuck)
onLocationChanged does not get called using fusedLocationAPI.requestLocationUpdates
Unable to get location updates
onLocationChanged not called on some devices
on locaton changed never gets called in android google client api
onLocationChanged isn't being called
Can someone point my errors? =S

I'll venture this answer... if it's helpful, great... if not, sorry...
I have a similar Activity that uses the FusedLocationprovider.
I'm no expert, and can't say WHY yours is not working, but mine is working, and I've noticed the following differences:
YOUR CODE:
private synchronized void buildGoogleAPIClient() {
//Configuring the Google API client before connect
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
}
private synchronized void buildLocationRequest() {
mLocationRequest = LocationRequest.create()
.setInterval(10000)
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setFastestInterval(1000)
.setSmallestDisplacement(1);
}
MY CODE:
protected synchronized void buildGoogleApiClient() {
this.mGoogleApiClient = new GoogleApiClient.Builder(this).
addConnectionCallbacks(this).
addOnConnectionFailedListener(this).
addApi(LocationServices.API).build();
createLocationRequest();
}
protected void createLocationRequest() {
this.mLocationRequest = new LocationRequest();
this.mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
this.mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
this.mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}
Differences:
1) You put:
if(mLocationRequest == null)
buildLocationRequest();
in your onCreate method. Is this necessary? Wouldn't mLocationRequest always be null in onCreate()?
2) Your methods are private, mine protected
3) your createLocationrequest() is labeled as 'synchronized' ... could is be not working because of this?
4) you use the setSmallestDisplacement() method. I have seen posts that say this method doesn't work properly and results in onLocationChanged() not being called.
5) You instantiate your LocationRequest with: 'LocationRequest.create()' and not "new LocationRequest()' could this be the problem?
Does this help?

Here is an alternate answer.
There is one line of code that is vital in order for onlocationChanged to ever be called:
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
mLocationRequest, this);
And in your case, this code resides very deeply in your code with many conditions needing to be met for this to be reached:
Conditions you require:
security exception not thrown
last location == null
(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
!(ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
button pushed
I would consider putting MORE LOGS in your code in order to determine that these conditions are in fact being met... trace backwards from:
LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
mLocationRequest, this);
PS - I see you're using the Android N permission model. I have yet to put my toes in that water due to the confusion it seems to create... I just set my target SDK = 22. :)
