title: How to get keystore file from Google Play to sign my app to publish
body: <p>I have implemented map in my app, during development it is working fine but after publishing this app map is not working.</p>
  
  <p>I have searched over Internet to solve this problem and I found solution as follows: build a signed apk by using existing keystore which can be found by Google Play where I have created a project to publish my app on Google Play store.</p>
  
  <p>playstore file might be here (google play):<br>
