[FIXED] Programmatically retrieve permissions from manifest.xml in android

Issue

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.

Solution

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;
}
