App not installed after signed apk

Question

I'm trying to install my signed apk, generated from Android Studio 1.5.1, I can not understand why the release version I can not install it, I set debuggable to false, I have only one MainActivity in the Manifest.xml, all looks ok, but the .apk do not install, anyone can explain to me why?

P.S

I uninstalled the debug version of my phone

You have to locate where the artifact of your release version is and install it onto your device, because when you hit run, it installs the debug variant onto your device even though you don't have to explicitly declare the debug build type. — Trash Can, Feb 01 '16 at 18:35
I generate signed apk in the source folder, so I copy and paste it on my phone and launch installer but it doesn't install — Michele Lacorte, Feb 01 '16 at 18:36
Try the adb tool to install your apk instead and see if it installs — Trash Can, Feb 01 '16 at 18:37
Where did you drop it to? Is it an emulator or is it your actual device? I don't think it is as simple as drag/drop for your phones file system but I could be wrong. — zgc7009, Feb 01 '16 at 18:43
It's a real device @zgc7009 i drag the apk for test and release it on Play Store — Michele Lacorte, Feb 01 '16 at 18:44
Like I said, cd into the location of your apk, and use the adb tool to install it instead — Trash Can, Feb 01 '16 at 18:44

I've solved by launch:

adb uninstall my.package.id

The app was already uninstall but the data had remained somewhere

while uninstalling the application, the data also gets removed. I wonder why in your case it still existed. – thedarkpassenger Feb 01 '16 at 19:03
