Android emulator shows nothing but blank screen

Question

I am a complete nOOb to Android programming and trying my hands at it for the first time by going through the tutorials. The problem is that I have created multiple emulator

Answer 1

I just started with android development recently and I had the problem with emulator showing black screen even when I was using software GPU acceleration. On executing the following command in tools folder in Sdk folder of Android

 $./emulator -accel-check

The output which is given below showed that KVM was installed correctly and was usable.

    accel: 
    0
    KVM (version 12) is installed and usable.
    accel

So I installed the following packages

$ sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils ia32-libs-multiarch

As I use Manjaro I didn't find all the packages in software repo. I was able to find only the following packages

1. qemu
2. libvirt
3. bridge-utils

Installing these helped me run AVD in both software and hardware GPU accleration.

Answer 2

The AVD is just booting up. Wait a bit and you'll see a flashing android and after that it will show you the lock screen.

use the intel AVD if you want it to be a bit faster.

Answer 3

I had the same problem, running on a Mac Book Pro bought in 2011.

I solved it by selecting "Use Host GPU" as the emulation option at the bottom of the "Create..." screen.

Answer 4

Tried all of the above. What eventually worked, was a combination of using software based graphics rendering, in combination of 'older' device images (nexus 7 works, nexus 10 doesn't). Go figure. And yeah, it's very slow.

Answer 5

Sounds like there are many possible solutions so here's how I solved my black emulator screen after something (Gradle?) updated in Android Studio:

Change the AVD's Graphics setting to "Software - GLES 2.0"

Update: so far, this isn't working on Play Store-enabled devices, because the Graphics setting can't be changed

Answer 6

Android emulator response time is very slow so you can try some alternative like https://cloud.genymotion.com/page/launchpad/download/

or

http://www.bluestacks.com/

both are very good option for testing application on development phase.
