Hi guys, I'm new on this part of android development using android studio and bluestacks emulator, since I started three days back I've been stucked on trying to display just a simple hello world from Android studio to bluestacks emulator. I have tried too many explanation gotten from Google and non has worked.

After successfully adding the emulator to android studio, I still get these follow errors below.

ADB rejected shell command(wm dismiss-keyguard): closed.

Error during sync: an existing connection was forcibly closed by remote host

Session app: error installing APK.

Please guys I will be glad if I get a fix and also get one to mentor and guild me along my quest to learn
