Android Emulator is not started through Jenkins

I am trying to set up my mobile automation pack in Jenkins. As a first step, when I try to launch a emulator using Jenkins Android Emulator plugin, I am getting below error

Below is the error

After reducing the emulator RAM to 768MB, I can rid off the above issue. However I cant see any devices connected in adb devices command. If you see the below log, it started and immediately stopped.

jenkins Emulator occasionally hangs indefinitely on startup

Problem: when I try to build an android project on Jenkins, emulator occasionally hangs indefinitely on startup and the job finished: NOT_BUILT.
I have Jenkins slaves running on Debian EC2 instances - not using any emulator snapshots, every run is fresh with a clean workspace, so I haven't been able to figure out the difference as to why sometimes they are starting correctly and more often not.
In "Common emulator options", I checked the option: 'Reset emulator state at start-up'.
Jenkins version: 1.642
Android Emulator Plugin: 2.13.1

What should I do to get over this darn issue?

I had the same issue and it turned out that adb was crashing. In my case the cause for the crash was a permission error. Try deleting the file /tmp/adb.log before running the job. Please see this thread for more information: Is it possible to fake a specific path for a process?
You could also add the -verbose option to the emulator to see more output that might help.

Android emulator plugin, launcher icon is not found

I am using Android emulator plugin with jenkins. Along with the android application, I also have a java project for uiautomator which is the part of build modules in main pom.
The maven goal is : mvn install
The uiautomator test is failing at the point where it is trying to assert the presence of application launch icon from "Apps" screen.
Do I have to install the application apk or does the plugin does it automatically as described in the plugin documentation(My plugin version is 2.10 and jennkins version is 1.531)
How do i know that the application is installed in the emulator.
The emulator is started without any problem.
The following is the part of the jenkins log:

Do I have to install the application apk or does the plugin does it automatically as described in the plugin documentation
The documentation does not say that your APK will be automatically installed.
But the plugin does provide a build step which will do this for you, if you provide the path to an APK file:
Under the "Build" section of your job configuration, select "Add build step" and choose "Install Android package".
In the "APK file" field that appears, enter the filename of the APK you wish to install. When a build runs, the APK will be automatically installed after the emulator has started up.

Why is Jenkins Android Emulator Plugin recreating my Emulator Snapshots in every build?

I use Jenkins to build one of my projects. The Android Emulator Plugin automatically starts an emulator with the following configuration:
Configuration of the Emulator Plugin:
.
Every time the job is running I get the following output:
Erasing existing emulator data... $
/ci/home/tools/android-sdk//tools/emulator -no-boot-anim -ports

shell input keyevent 4 [android] Giving the system some time to settle
before creating initial snapshot... $
.
.
localhost:64471 shell log -p v -t Jenkins "Creating snapshot..."
[android] Creating snapshot... $
Full log below.
It seems that the plugin is creating a new emulator every time and is not using snapshots.
This takes something between 2 and 4 minutes depending on the emulator configuration.
The plugin creates .avd and .ini files in the .android/avd directory inside the job folder. The avds are not deleted after the run process.
If I disable the use snapshots config the emulator needs less then a minute to start.
Is this an issue with the emulator plugin or are snapshots not possible because of my configuration?
I hope that using snapshots will speed up my building process a lot.

A bug was introduced in SDK Tools r20, whereby trying to list the available snapshots (via the emulator -snapshot-list command) would result in a crash.
Since the command crashes without listing the available snapshots, the Android Emulator Plugin believes that there are no existing snapshots, which causes a new snapshot to be created in every build.
I discovered that these crashes only occur with certain versions of the emulator application, i.e. it is possible to avoid the crash.
Thankfully, the Jenkins plugin lets you select the emulator binary to run.
So you can work around this problem by going into your job configuration, pressing Advanced… in the emulator config and selecting the "emulator-arm" (or another) binary.

In addition to Christopher Orr's answer, there is another possible cause. In my environment, emulator -snapshot-list listed the size of my snapshot as "1.0G". The pattern that matches snapshots in the Android Emulator Plugin as of 2014-01-14 matches whole number megabyte values.
I submitted a pull request to address that cause.
