I am having this error where my android emulator is transparent.. I tried restarting my laptop, restarting Android Studio, Deleting the device and making a new one but still no luck! I've seen a question like this here but there is no step by step instruction on how to do it! and instructions are not clear at least for me can anyone help me? I've been trying to fix this for hours
again this is the link to the same question
I HAVE FOUND THE SOLUTION.
First this question has been asked and answered here but for me the solution wasn't explained properly so here is a step by step solution to this problem.
Step 1
Go to your Android Virtual Device Manager.
Step 2
In the device manager you will find lists of your emulators and here under action click the pencil option which will open the Virtual Device Configuration.
Step 3
From here in the Emulated Performance option change the graphics to Software instead of automatic.
This is the most detail I can explain this and hope to help people who will get the same problem as me will be solved.
