Why is the Android emulator screen blank?

I have recently installed Android Studio and all its updates using sdks manager. When I try to start the emulator i can see this:

emulator -netdelay none -netspeed full -avd Nexus_5_API_21_x86

HAX is working and emulator runs in fast virt mode

It seems good. The emulator start but only thing i can see is a black screen. I use the default AVD created by the app. It has google api's x86 system image, 1gb ram, 64mb vm heap and 200mb intel storage. I tried to uncheck "Use Host GPU" but it did not solve the problem.

Put Graphics in SOFTWARE in the emulator configuration, it worked for me.

Ran into this after running a long overdue upgrade to Android Studio, where existing settings were imported into the upgrade.

Getting all the SDK updates was not enough. The issue was finally resolved after Invalidate-Cache & Restart

I'm embarrassed to say I lost too much time before I realized I just needed to click the Power Button to wake it up.

I ran into the same your issue, this is what I did that works: My one starts working with Nexus_4_API_25 (tried even with Nexus 6, Nexus 5 and Nexus One none of them was working!!) Create a new ADV from Android Studio ( bare in mind that i didn't allow the new front and rear camera to the new device, so switch them off) So go to Terminal and go to the folder where your emulator is and lists your emulators, my one:

~/Library/Android/sdk/tools/emulator -list-avds

After run your emulator with the gpu hosted on your machine:

~/Library/Android/sdk/tools/emulator -avd Nexus_4_API_25 -gpu host

It will start the emulator and then you can run your app in it. Hopefully this can helps someone else.

if you have avast antivirus installed In Avast antivirus under Settings (parametres) tab > Troubleshooting (depannage), you should uncheck "Enable Hardware-assisted Virtualization" ("activer l'assistance a la virtualisation").

Now restart your computer it should work if not re-install the Intel's HAXM which can be found under ~SDK_LOCATION\extras\intel\Hardware_Accelerated_Execution_Manager

Same problem for me, I solved it by using x86_64 system image instead of x84, maybe x86 image has some bug on some host system, e.g. Windows 10.

Faced the same issue, I solved by reducing the AVD version. In the AVD manager choose create a lower version e.g. I was using Nexus 5 and created a Nexus 4 which worked well.

If this solves it means you need to upgrade your machine, RAM etc.

I had the same issue that the x86 emulator would hang during startup (black screen, no logo). The answer to my problem had to do with me using Eclipse ADT with an old SDK prior to upgrading to Android Studio on the same computer.

I am running Ubuntu and the configuration files are stored in the .android folder of the home directory, i.e. ~/.android. I saw references to the old SDKs in the config files and deleted the whole folder. After that the x86 emulator started working again.

In hindsight, what gave it away was that when I started using ARM images the emulator worked. I had only used x86 images with qemu in the past.

Also look at your skins - some have found it works with the WVGA800 skin. Others here have found it's due to the high RAM requirements of the Nexus 5 AVD itself. I think Nexus 5 takes almost 1600. Try either decreasing the RAM allocation in the AVD ('Advanced settings') - or reinstall HAXM with a higher RAM limit.

I ran into this issue, and what solved it for me was unchecking everything that has to do with snapshots.

I assume that my snapshot was corrupt somehow.

Uncheck loading and saving to snapshots.
