Video Demo:
In Marshmallow (Api level 23 or higher), Google had changed the way of asking permissions. If we want to access the camera, gallery etc of the marshmallow user, then we have to asked these permission during runtime otherwise over app should crash. There are two type of permission Normal Permission and Dangerous Permission
NORMAL PERMISSION- Normal permission in marshmallow is directly granted while installation of application. Examples of normal permission is given below:
DANGEROUS PERMISSION- Dangerous Permissions which provide access the personal data of user such as gallery, location, camera etc. Examples of dangerous permission is given below:In Marshmallow (Api level 23 or higher), Google had changed the way of asking permissions.

NORMAL PERMISSION- Normal permission in marshmallow is directly granted while installation of application. Examples of normal permission is given below:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.BLUETOOTH"/><uses-permission android:name="android.permission.READ_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_CALENDAR"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_SMS"/>In this tutorial I will cover the runtime permission in Marshmallow in android kotlin. DOWNLOAD SOURCE CODE FROM BELOW.
