Android application not asking for camera permission

I am developing an SDK(.aar) which third parties can consume. In my sample application when I use the aar, I can see that the application doesnt prompt for the camera permission. When I open the aar and see its manifest.xm, it contains the below:

<!-- WRITE_EXTERNAL_STORAGE is needed because we are storing there the config files of KM -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.read_external_storage" />
<uses-permission android:name="com.samsung.android.providers.context.permission.WRITE_USE_APP_FEATURE_SURVEY" />
<uses-permission android:name="android.permission.CAMERA" />

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-feature android:name="android.hardware.sensor.accelerometer" />

Since the camera is present as a required permission can anyone tell me why it is not coming up when installing the sample app.

Here is how i check for permissions:

    public boolean permissionsGranted() {

    boolean allPermissionsGranted = true;
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1) {
        boolean hasWriteExternalPermission = (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
        boolean hasReadExternalPermission = (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
        boolean hasCameraPermission = (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED);
        if (!hasWriteExternalPermission || !hasReadExternalPermission || !hasCameraPermission) {
            allPermissionsGranted = false;
        }
    }
    return allPermissionsGranted;
}

This is how i make the request if permissionsGranted() method returns false

 String[] permissions = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.CAMERA, android.Manifest.permission.READ_EXTERNAL_STORAGE};
                        ActivityCompat.requestPermissions(this, permissions, 1);

And you have to override onRequestPermissionsResult method, below is what i have in mine.

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode) {
        case 1: {
            boolean startActivity = true;
            for (int i = 0; i < grantResults.length; i++) {
                if (grantResults.length > 0 && grantResults[i] != PackageManager.PERMISSION_GRANTED) {
                    String permission = permissions[i];
                    boolean showRationale = shouldShowRequestPermissionRationale(permission);
                    if (!showRationale) {
                        Intent intent = new Intent();
                        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                        Uri uri = Uri.fromParts("package", getActivity().getPackageName(), null);
                        intent.setData(uri);
                        startActivityWithIntent(intent);
                        Toast.makeText(this, "Enable required permissions", Toast.LENGTH_LONG).show();
                        startActivity = false;
                        break;
                    } else {
                        Toast.makeText(this, "Enable required permissions", Toast.LENGTH_LONG).show();
                        break;
                    }
                }
            }
            if(startActivity) {
                getActivity().finish();
                startActivityWithIntent(getIntent());
            }
        }
    }
}

public void startActivityWithIntent(Intent intent){
    startActivity(intent);
}

showRationale is to check if user ticked never ask again, if so then i start the settings activity so that user can enable permissions.

Let me know if you need more clarity

Since Android 6.0 you have to request the permssions at runtime and the user is not prompted at the time of installation.
