The app closes due to getting permissions without any error messages

My application is closed immediately after launching due permission request without an errors. This is my code, is here something wrong? Also, I post manifest file here to let you check it. I need bluetooth permission and data access.
The probem is in this line:
ActivityCompat.requestPermissions(this, permissions, REQUEST_MICROPHONE);
If I comment this, application will not close after launching.
private static final int REQUEST_MICROPHONE = 1;
private void askPermissions(){
String[] permissions = {Manifest.permission.RECORD_AUDIO,
Manifest.permission.BLUETOOTH,
Manifest.permission.BLUETOOTH_ADMIN,
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.BLUETOOTH_SCAN,
Manifest.permission.BLUETOOTH_CONNECT};
if (!hasPermissions(permissions)) {
ActivityCompat.requestPermissions(this, permissions, REQUEST_MICROPHONE);
}
}
private boolean hasPermissions(String[] permissions) {
if(permissions != null){
for(String perm : permissions){
if(ContextCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED)
return false;
}}
return true;
}
And the Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.myapp">
<uses-sdk android:minSdkVersion="21"

It was discrepancy between Android version and way to get permissions. Unfortunately, it was not any errors or other communications and I have to find a problem by luck.

Cordova Android - can't open camera - READ_EXTERNAL_STORAGE

I am trying to open a camera on my Cordova app since moving it over to Android Studio and now it has stopped working.
I get no popup of permissions, or anything on the user side to show me otherwise.
I get the following error in the Android Monitor
com.ontrac.nutshellmobile E/ViewRootImpl: sendUserActionEvent() returned.
E/DatabaseUtils: Writing exception to parcel
java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=8324, uid=10182 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()

I am running API 26 for the compile SDK version on the project structure.
My build gradle files contain the SDK versions of
minSdkVersion 23
targetSdkVersion 25
compileSdkVersion 26
buildToolsVersion '26.0.0'
I have tried moving the permissions over to the Cordova Android manifest but no luck. I cant seem to figure out what is causing the error.
Any help would be greatly appreciated. I can give more information if needed.

In order to open camera, you have to install cordova-plugin-android-permissions.
you have to ask for 2 permissions: READ_EXTERNAL_STORAGE and CAMERA, and open the camera in the callback function of the 2 functions.
example of the js code:
function takePicture() {
var permissions = cordova.plugins.permissions;
permissions.requestPermission(permissions.READ_EXTERNAL_STORAGE,
function (status) {
if (!status.hasPermission)
error();
else
permissions.requestPermission(permissions.CAMERA, success.bind(this),
error);
function error() {
console.warn('CAMERA permission is not turned on');
}
}
, error);
function error() {
console.warn('READ_EXTERNAL_STORAGE permission is not turned on');
}
function success(status) {
if (!status.hasPermission)
error();
else
openCamera();
}
}
function openCamera() {
navigator.camera.getPicture(onSuccess, onFail, {
quality: 25,
destinationType: Camera.DestinationType.DATA_URL
});
function onSuccess(imageData) {
var src = "data:image/png;base64," + imageData;
console.log(src);
alert('got picture!!!');
}
function onFail(message) {
alert('error ' + message);
}
}
takePicture();

Android permission dialog not displaying

I have found a few other questions about this issue but none of the answers have solved it for me. I'm trying to request the fine location permission, but there is no dialog shown. Here's what I'm doing:
int permissionCheck = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);
if(permissionCheck == PackageManager.PERMISSION_GRANTED) {
Log.d("Location","Location permission already granted"); // Not logged
// Do other stuff
}
else {
Log.d("Location", "Requesting location permission"); // This is logged
ActivityCompat.requestPermissions(this,
new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE_ENABLE_LOCATION);
}
No dialog appears, and onRequestPermissionsResult is not called.
This is the manifest:

Here are some tidbits from the gradle file:
compileSdkVersion 23
buildToolsVersion '21.1.2'
defaultConfig {
minSdkVersion 12
targetSdkVersion 23
}
This is in a FragmentActivity, don't know if that matters. I have uninstalled the app and run it so there should be no permissions already accepted. This is on a Nexus 7 running 6.0.

Why not try this library: https://github.com/tajchert/Nammu. It worked for me.
Nammu.askForPermission(activity, String[] permissions, new PermissionCallback() {
#Override
public void permissionGranted() {}
#Override
public void permissionRefused() {}
});
EDIT
I created a library that encapsulates the whole thing and makes it much more easier. It also shows a customisable explanation dialog before the actual request.
Use this library: https://github.com/ayz4sci/permissionHelper
Usage:
To perform an action that requires Android permission, call permissionHelper.verifyPermission. It accepts the following parameters:
String [] - description of each permission required, this will be displayed to the user in the explanation dialog.
String [] - an array of Manifest permissions
PermissionCallback - you put the actions you want to perform when permission is granted or rejected.
See example below:
permissionHelper.verifyPermission(
new String[]{"dial this number", "take picture"},
new String[]{Manifest.permission.CALL_PHONE, Manifest.permission.CAMERA},
new PermissionCallback() {
#Override
public void permissionGranted() {
//action to perform when permission granteed
}
#Override
public void permissionRefused() {
//action to perform when permission refused
}
}
);
