permission-android

Wrapper for Android permission API

Usage

Make sure that your root project build.gradle file has this section

ext {
    compileSdkVersion = 25
    buildToolsVersion = '25.0.3'
    androidSupportVersion = '25.4.0'
}

Add this code to your Activity:

private val PERMISSIONS_REQUEST = 1
private var permissionDialog: PermissionDialog? = null    

//  Put this in some place where user is ready to grant permission
{
    permissionDialog = PermissionDialog(this,
            PERMISSIONS_REQUEST,
            arrayOf(Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.CAMERA, Manifest.permission.RECORD_AUDIO),
            R.string.app_name,  //  Permission rationale dialog title
            R.string.permission_rationale,  //  Permission rationale dialog message
            false //  should we force permission rationale dialog show
    )
    permissionDialog?.startRequestPermission()        
}

override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
    //  Delegate this callback to process result
    val granted = permissionDialog?.onRequestPermissionsResult(requestCode, permissions, grantResults)
    if (granted?.isNotEmpty() ?: false) {
        //  Here granted permissions come
    }
}
