No, it's not possible. The manifest get's parsed at compile time -> you can't add meta-data at runtime.

for add any metadata dynamically you can use this code:

try {
            ApplicationInfo applicationInfo = getPackageManager().getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
            applicationInfo.metaData.putString("Your Key", "Your Value");
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
