I'm developing a application that works on linux. I want to port this to the Android SDK Emulator. But everytime I start the application the emulator crashed with a segmentation fault.
Somebody has any clue why a selfmade program that's running on the Android Emulator could crash the entire emulator?
Can you post up some code examples / logs of what is happening? You don't provide enough information for us to suggest why it would fail.
Best thing I can advise is to create a new emulator (only takes a few clicks) and try deploying your app on that, possibly try a different version.
If you can post up some logs/code examples of what might cause this, we can provide better answers
Another debugging point to try would be launching a demo application/Hello Android on the emulator, to see if it is your application specifically.
Apparently there was a bug in the version of the emulator that I used. When I updated the emulator to the latest version, it was solved.

After I have updated my android studio to 2.3 & above, emulators become slow and also I am also using x86 system images. I have also tried to use Software Gles 2.0
as described in other recent answers but nothing is working.
After starting up the emulator it stops on main screen and becomes un-clickable anywhere.
Even Api 15 & 16 emulators slowed down even though they are not heavy.
I have also re-downloaded android sdk.
note: I do not want to use gennymotion or any other emulator
please provide any help regarding Android Emulator.
Try changing the grahics to Hardware-GLES 2. Then run your emulator to compare your result. I think it is much more faster.
I have tried all these options but nothing worked, its only working after I have uninstall and reinstall the new android studio 2.3.
Please read my blog for the correct solution.

I'm using Cloudpebble to develop a watchface for myself. Everything compiles well and I've not had troubles sending the face to my watch until now.
After compiling the watchface and linking to the phone, it returns an error of "Installation failed. Check your phone for details." However, the phone does not shed any light on what these details might be.
I've checked the usual suspects such as full watch slots and inability to connect to phone, but those were not issues in my case and I'm rather stumped as to what the problem might be. Any help would be greatly appreciated.
Pebble App Version:
2.1.0-beta9 2.1 (Android)
Watch Firmware: 2.7 2.8
Watchface Source: GitHub
UPDATE 11/20:
I didn't mention before that the phone app would crash often when attempting to load my watchface on the watch because I chalked it up to beta software. Today brought watch firmware 2.8 and phone app 2.1 proper, and while the phone app no longer crashes, the mysterious error continues without additional information on the phone.
The answer to my particular issue, as it turns out, was that I had unused fonts. It's not a very obvious problem, so I hope this helps others out.
The main issue really was poor error reporting from cloudpebble due to the lack of error clarification returned from the pebble app to cloudpebble.
I have opened an issue on the cloudpebble github (that's where I found the answer) so if any further developments happen, they'll more than likely be there.
I found that the app had to be on a specific page for it to properly install on the pebble. I found this to be true if I installed on the terminal using the Pebble commands or using the web IDE CloudPebble.
The app has to be on the "My Pebble" scene/activity. Make sure when you attempt to install an app to Pebble that you are on that scene/activity regardless if you are installing using the web IDE or the command line.
So i'm having awful trouble trying to get the Emulators in the Android SDK to start up. I can create the AVDs just fine, and then when hitting the 'start' button from the SDK Manager, bring up the small loading console window, indicating that the emulator is launching. However, after that, nothing happens!!
I have read many threads and posts with people having the same problem, maybe to do with the settings requiring too much memory, with some people waiting 30 minutes for the emulator to load!!
When trying to run the AVD emulator through terminal, I simply get a 'Bus Error' with no further indication of what could be going wrong...could it be a memory issue?
What I did to get where I am now:
Download the Android SDK package for Mac. I'm extracting the sdk only, not eclipse. I'm on Mac 10.6.8.
Install the SDK, and download the latest version of Android in the SDK Manager, along with default tools.
create a AVD and hit start.
window pops up to boot the emulator, that process is complete and window closes.
Nothing happens.
My knowledge of the sdk tools are very limited, all I want is to be able to do some testing...
Any help greatly appreciated!
Thanks
Actually, the simplest way to get emulators running right now is probably GenyMotion. They provide an interface, and pre-configured emulator images to make it pretty simple to get running.
This is not an endorsement (I use the standard ADT myself) but a lot of people find their tools useful.
Here is my suggestion: instead of using AVD, start using espresso and virtual remote android hardware emulator from Google servers - also known as android-test-kit. You will have the possibility to run and test you App on several different devices, without the need to spend money on actually all different devices for developing and testing purposes before releasing your Apps. You find further details here:
android-test-kit
Why Espresso
The 2 videos are somewhat long, but worth watching.
Taking this approach will solve your problem, save you money, and improve your productivity.
I run into the same issue on my mac 10.6 and it only works if i do
emulator64-x86 -avd my_android
Besides, my virtual device has to configured using x86 but not ARM
maybe this link can help you.
I have have been using the Android emulator both and the command-line and in Intellij for some weeks running ApiDemos and my own apps with no problems.
Now, without any exceptions or messages to indicate the reason why the emulator will only run the emergency call app and nothing more.
Is this a bug? If so, how do I create an issue for the Android SDK dev?
I'm cautious to load any .apk now into my handset to see if the condition is the same.
Particulars follow:
OS: Ubuntu 12.04
Android SDK: 4.1 (ICS).
JDK: 1.7.x
Maybe a stupid answer, but are you sure you didn't set a PIN code on the lock screen? This will load the PIN entry screen whenever you load the emulator but still allow you to make emergency calls.
You have to set a PIN on Android ICS when you save new security certificates, which caught me out.
You need to use 2 GB of RAM o avoid that problem in your android emulator.
I am developing an application on android 3.1 Honeycomb. It force-closes on Asus epad.
I don't have an Asus Epad to check why it force-closes, so I want to try it on an Asus epad Emulator. I updated the ADK for eclipse but it doesn't provide an Asus epad Emulator or add-on for it.
In other words, my main problem is that I want to test my application on an Asus emulator.
Does anyone know how I can do this?
Update----
It's showing error on background process & it's a null pointer exception. But now I found another way to do this background code so it must work now.
Thanks for all your comment.
Still if any one find out plugin or package or a way to create emulator which work as Asus Epad.
Thank You.
I am pretty sure that it the app gets force closed on an actual Asus epad, it will get force closed on the emulator too.
You can try to debug your application using LogCat in Eclipse and look the stacktrace to figure out what is going wrong.
Could you post details about what exactly does it crash on? You could monitor the logs in DDMS and check the stacktrace to analyze what exactly is it crashing on.
Unless you post specific details about a problem, there's very little I or anyone else could help you out with.
