I recently started with Android (developing in Java for two years) and did my first application. I did simple calculator project with working java code which is running correctly on emulator in Android Studio. Then I did this: run 'app' (everything working in emulator and also on attached phone via USB) > searched for generated apk (apk without sign) > transferred to my Samsung s4 mini (via USB) > installed > application works fine like on AS emulator or attached phone via USB. Then I tried to create signed APK instead and here comes problem. I build signed APK (created keystore and everything) > transfer to phone > install > run application and on my logcat is popping this text when i started app:

Here is what looks strange from log above "android.permission.INTERACT_ACROSS_USERS_FULL", but application didnt crashed yet.
Then I pressed (in this example) number five on calculator which should add "5" on display, but when i press button, application crashes with this log:

This is strange part after pressing number 5: Could not find a method five(View) in the activity class com.cka.kalkulajda.MainActivity for onClick handler on view class android.widget.Button with id 'fiveButt'.
I'm sure everything regarding java code is correct (it works on emulator and also unsigned APK and ALSO when I'm not run project on emulator, but via USB on my phone), for example on emulator I press number 5 and it adds number 5, but when trying press any button ON SIGNED APK, app just crash.
I Googled everywhere but there is no straight answer to this or any real solution that works.
com.cka.kalkulajda is project..... five(View) method is attached to fiveButt ID of button ...every help is highly appriciated
TL;DR when I running project on emulator - works.... when running project via USB on phone - works... installing generated unsigned APK to phone and run - works..... installing built signed APK to phone and run - works with "bitching" (see log), but after pressed any button app crashes (see log)
edit: I'm adding build.gradle app
apply plugin: 'com.android.application'
