I created a small game on Godot 3.0 and it works fine on my desktop, but when i export it for Android and try to install the .apk on my phone, it shows the message: "App not installed".
I set up everything correctly, the adb, the jarsigner, the debug.keystore and it still doesn't work!
One thing that i found strange is that i made a smaller project before this one, with just two scenes and it worked perfectly, even the installation. So i'm really confused with this problem. I just doesn't want to install.
I've searched a lot already and i hope somebody can help me here.
ps: My phone is a Samsung Galaxy s7
