title: Android Studio wont debug my app in my phone
body: <p>I have very big difficulties of understanding what might be an issue, why android studio wont debug my app.
  I developed it, wanted to do release.apk from the file and now i am in front of problem that app crashes and does not give me any error at all.</p>
  
  <p>Last thing i did was deleting debug.keystore from .android folder
  Also i generated signed APK.
  One thing to notice that my app is using google play services. Maybe that might be an issue why it wont work correctly. 
  Also my google_maps_api.xml is in /debug and /release folders.</p>
  
  <p>I reseted my phone to factory settings,
  Allowed to put developer mode again and set usb debugging enabled.</p>
  
  <p>I deleted all breakpoints and put only one to line.
  Nothing seems to work.</p>
  
  <p>Also here is the error when i want to install my application for the second time:<a href="https://i.stack.imgur.com/8olL4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8olL4.png" alt="enter image description here"></a></p>
  
  <p>Help me!
  I need to finish my project so i can put it in google play store!</p>
