Android install error

Hey!
I try to make a game for android. I tried to install the SDK but this happened:

I tried it again and this popped up:

After the directory and after “Shield:” it says: “Access Denied”.

I do not really know what to do.
Unreal engine does not see my phone in the launch options and i can not package the game for android.
I get an error for rungadle.bat.

And this the error that i get when i try to package the game.
