In addition to all answers, if the clients are using Android 6.0, Android added new permission model for (Marshmallow).

Trick: If you are targeting version 22 or below, your application will request all permissions at install time just as it would on any device running an OS below Marshmallow. If you are trying on the emulator then from android 6.0 onwards you need to explicitly go the settings->apps-> YOURAPP -> permissions and change the permission if you have given any.
