App doesn't run on both Emulator and Device on MAC, I only get an error saying client not ready yet.

I tried Invalidating and Restarting Android studio , tried to close app, uninstall, rerun , disabling instant run ,Clean Project, Rebuild , Deleting Gradle but none of these worked.

below is the run log that I'm getting.

$ adb push /Users/username/app/App/build/generalDebug-1.6.1-530966e6.apk /data/local/tmp/com.site.app $ adb shell pm install -r "/data/local/tmp/com.site.app” Success

Client not ready yet..

Does anyone know a solution for it?
