Don't know why you copy both apk and instal both apk One extSdCard and another storage/extSdCard/

If you have Kitkat and name for external SD is extSdCard or storage/extSdCard/ you must copy only one apk.

First you must know if your external SD is extSdCard or storage/extSdCard/, when you know this and if you use Kitkat, you mus take apk example:extSdCard/android/data/..... becouse Kitkat don't run apk from external SD in normal way, so if you have rooted phone and if you run SD Fix then you can use apk with name extSdCard but if your device is not rooted you must take apk that have in name android/data/.....
