Steps for uploading your android softphone to google play (market):
Warnings:
Occasionally Google Play might display some warning regarding the target API level, size optimizations, native code, debug symbols and others. These are usually intentional, such as using low minSDK version to remain compatible with old devices, but we also optimize the app for the latest android versions. You can safely ignore all these warning. Our app is well optimized and these warnings are false alerts. If you will get a "Target API level" related warning on the Rollout page, you just need to close the popup and after that you should be able to continue.
