Android emulator won't start, gets stuck in a loop

Issue

I know there are a lot of issues with the Android emulator and that StackOverflow nearly overflows with questions about it. I know, I've been through most of them looking for an answer to my problem :)

I had the usual HAXM problems when I started but I fixed the VT settings in my BIOS and I reinstalled HAXM.

Now when I start my emulator, either through Android Studio or command line, it won't start and it gets stuck in a loop. The loop looks like this:

Run output

Note: The environment variable $ANDROID_SDK_HOME is set, and the emulator uses that variable to locate AVDs.

This may result in the emulator failing to start if it cannot find the AVDs in the folder pointed to by the

given environment variable.

ANDROID_SDK_HOME=C:\Users\maffe

emulator: device fd:1160

HAXM is working and emulator runs in fast virt mode

emulator: warning: opening audio input failed

creating window 102 107 646 1147

emulator: UpdateCheck: current version '24.4.1', last version '24.4.1'

My .avd folder is located at C:\Users\maffe and as you can see HAXM is working.

My emulator device is:

• Nexus 6
• Lollipop
• API 22
• Target is Google APIs
• CPU x86
• Uses Host GPU
• No camera
• 1536MB of RAM
• 2GB of VM heap
• 200MB of internal storage
• Enable Device Frame is checked

I am myself running the following computer:

• Intel Core i5-3470 CPU @ 3.2GHz
• 12GB RAM
• 64 bit Windows 10
• About a 2 week old setup (from a fresh Windows installation)

Any idea why it would get stuck on the loop shown in the Logcat output? All I see is the black screen with the 'Android' sign on it (which of course is better then the black-only-screen I get if I uncheck Use Host GPU).

Solution

I found the problem. I had accidentally set the VM heap to 2GB. I should've left it at 64MB :)
