Programmatically retrieve permissions from manifest.xml in android

Question

I have to programmatically retrieve permissions from the manifest.xml of an android application and I don't know how to do it.

I read the post here but I am not entirely satisfied by the answers. I guess there should be a class in the android API which would allow to retrieve information from the manifest.

Thank you.

You can get an application's requested permissions (they may not be granted) using PackageManager:

PackageInfo info = getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_PERMISSIONS); String[] permissions = info.requestedPermissions;//This array contains the requested permissions. 

I have used this in a utility method to check if the expected permission is declared:

//for example, permission can be "android.permission.WRITE_EXTERNAL_STORAGE" public boolean hasPermission(String permission)  {     try {         PackageInfo info = getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_PERMISSIONS);         if (info.requestedPermissions != null) {             for (String p : info.requestedPermissions) {                 if (p.equals(permission)) {                     return true;                 }             }         }     } catch (Exception e) {         e.printStackTrace();     }     return false; }
