Answer 1

What you have to do is just put the permission sin a String array like

int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
        android.Manifest.permission.READ_CONTACTS,
        android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
        android.Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.ACCESS_FINE_LOCATION
};

and to Check the permission use then

public static boolean hasPermissions(Context context, String... permissions) {
    if (context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

Now the Last thing to do finally is use it in oncreate() or onStart()

if(!hasPermissions(this, PERMISSIONS)){
        ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
    }
