Permission constants

In AndPermission, permissions and permission groups are placed in the class Permission.java.

Reference permissions constant

We should use Permission to refer to permissions.

For example, referencing a single permission:

Permission.CAMERA

Permission.CALL_PHONE
...

For example, referencing a single permission group:

Permission.Group.LOCATION

Permission.Group.PHONE
...

Turn permissions into text

When we request some permissions failed, we should prompt the user to set permissions to allow these, For convenience, AndPermisison provides a way to turn permissions into prompt strings:

/**
 * Turn permissions into text.
 */
public static List<String> transformText(Context context, String... permissions);

/**
 * Turn permissions into text.
 */
public static List<String> transformText(Context context, String[]... groups);

/**
 * Turn permissions into text.
 */
public static List<String> transformText(Context context, List<String> permissions)；

For example, let's add some permissions, assuming these permissions are the request failed:

List<String> deniedPermissions = new ArrayList<>();
deniedPermissions.add(Permission.READ_SMS);
deniedPermissions.add(Permission.CALL_PHONE);
deniedPermissions.add(Permission.READ_EXTERNAL_STORAGE);

List<String> permissionNames = Permission.transformText(context, deniedPermissions);
String permissionText = TextUtils.join(",\n", permissionNames);

At this point, permissionText result is:

Sms
Phone
Storage

We can prompt the user to allow these permissions in the system Setting. This method supports internationalization.

Special Note: The AndPermission.hasAlwaysDeniedPermission() can only be called from the onDenied() callback and can not be used elsewhere.
