3. Permissions in android
• Android apps must request permission to access sensitive user data
(such as contacts and SMS or user location) or certain system features
(such as the camera and internet access).

4. Request permission in Android
• Starting from Android 6.0 (API 23), users are not asked for
permissions at the time of installation rather developers need to
request for the permissions at the run time.
• Only the permissions that are defined in the manifest file can be
requested at run time.

5. Types of Permissions
• Install-Time Permissions: If the Android 5.1.1 (API 22) or lower, the
permission is requested at the installation time at the Google Play
Store.
• If the user Accepts the permissions, the app is installed. Else the
app installation is cancelled.

6. Cont..
• Run-Time Permissions: If the Android 6 (API
23) or higher, the permission is requested at
the run time during the running of the app.
• If the user Accepts the permissions, then that
feature of the app can be used. Else to use
the feature, the app requests the permission
again.

7. Steps for Requesting permissions at run time
• Declare the permission in Android Manifest file: In Android
permissions are declared in AndroidManifest.xml file using the uses-
permission tag.
• <uses-permission
android:name=”android.permission.PERMISSION_NAME”/>
<uses-permission android:name="android.permission.CAMERA" />
