Good afternoon / evening,

So here I bought a samsung one. I downloaded from my phone applications (dictionary and translator) in the format jar, jad and apk, and I put on my phone via an adapter on the micro SD.
I open the application on my phone, and they clearly tell me''file type not supported.''

I tried typing the code * # 9998 * 4678255 #, but when I press the green button, it loads and returns to the beginning.

I like to know how to fix this please.
Thank you

Ps: I searched the internet, and I think it is a story with java ... I want to say that I have nothing installed on the phone.
