EGL_emulation failed to establish connection to host - android

Question

I am trying to run a simple OpenGL program in Android. I am running this in an Android 4.1 emulator. I switched on its GPU emulation and it worked fine yesterday. When I ran that today, initially it was hanging saying, OpenGL taking time to render - Wait or Close dialog box. After few runs again it was crashing saying

E/EGL_emulation(2637): Failed to establish connection with the host

followed by

I guess the emulator is not able to take control of the GPU of the system, so how do I avoid this error? How do I rectify this problem?

Thanks in advance. :)

Oh!.. a simple restart of the emulator solved the problem for me. :) — Chaitanya, Nov 30 '12 at 06:42
What the hell? Same problem and definitely didn't solve it for me. — michaelsnowden, Nov 15 '13 at 10:43
I had this problem in the Genymotion emulator, running android 4.3. I just closed and restarted the emulator, and it worked... — IgorGanapolsky, Dec 09 '13 at 15:51
Couple of times it happened to me as well and it didn't turn up good even after several times of restarts. I had to delete that particular emulator, recreate it afresh then bang-on...it worked :) — Ramakishna Balla, Dec 30 '13 at 18:53
This isn't really a solution but I had a lot of problems testing my OpenGL apps on the emulator. Even ones worked fine when I ran them on the same physical device it was supposed to be emulating. I would recommend just getting a physical device to run OpenGL apps on. — ebeilmann, Feb 14 '14 at 04:59

This happens to me when my computer came out standby. Restart your virtual device.

It happens every time after mac sleeping. Need to fix reason, not consequences. Any solution? – IliaEremin Aug 25 '14 at 12:05
Any idea why this is happening? – Jakub Arnold Sep 11 '14 at 13:34

This doesn't seem to be an answer to the question and also it's been mentioned in the comments. – Ean V Feb 13 '14 at 23:14
For me, the exact solution crashed Genymotion on to different computers, so it came from the code, not from the simulator, even if restarting it can help. – Léon Pelletier Mar 19 '14 at 01:14
