Android Dynamic Get Permissions

changes in Android permissions

In previous versions of Android6.0, Android's permissions were all configured at the time of installation. However, this often leads to some security problems.

Google's solution:

There are two main categories of permissions in Android:

Normal: Permissions do not directly relate to the user's privacy. If your app configures this class of permissions in the manifest manifest file, the system automatically agrees.

Dangerous permissions allow the app to access the user's privacy data. If your app is configured with this class of permissions in manifest, it will take a long time for the user to agree to such permissions.

Note: If your app requires a dangerous permission, you must check for this permission every time you perform an action that requires this permission. The application user can always cancel this permission, and cannot consider agreeing to have it permanently.
