I know similar question is posted here. I uploaded an app to Google Play Store but it is incompatible with all the devices. The app is actually a SignalR based chat applicat
Finally i solved the problem.Here two solutions have been posted.
Solution 1 : using aar files
Step 1
First i convert my eclipse project into Gradle.
Step 2
Downloading latest SignalR from this link.Generate the aar files. Add these files as dependencies.
Step 3
Updated my Manifest file.I missed some permissions for location support. Now this is the new AndroidManifest.xml
Ofcourse it have application tag and activities as well.
Solution 2: using jar files
Step 1
Create a directory named "libs" inside your main package and paste all the jar files.You can download jar files from this link

Step 2
Add dependencies in build.gradle of main package/app

Step 3
Now this how my project's main build.gradle looks like.

Step 4
This is how my settings.gradle looks like

Step 5
After doing all these steps you still have import errors.So invalidate cache and restart

Final Output on Google Play
Now it supports over 7K devices
