Application crashes at startup (Lollipop 5.1.1, Tablet)

My application is showing very strange behavior for a tablet device, it crashes as it launches (Lollipop - 5.1.1 Tablet device, without any meaningful logs) though it runs fine on mobile devices even including Lollipop - 5.0 phone device with almost same log report

custom Android Virtual Device: System UI Stopped, Launcher Stopped

I created an AVD with the properties below to emulate a customer's device. Each time I start it up, it gives the "Unfortunately, System UI stopped" dialog and, when dismissed, the "Unfortunately, Launcher stopped." dialog.
Tweaking the parameters (at least, those which don't alter the essential characteristics of the device) using advice from:
Android emulator error: "System UI has stopped"
Unfortunately System UI has stopped
Android 4.0 emulator always has a crashing Launcher?
https://daviddesmet.wordpress.com/2013/07/26/android-avd-unfortunately-system-ui-has-stopped/
results in the same outcome.
Variations tried
skin 320x320, 320x321
Google API / non Google API
heapsize 16, 32, 64, 128
mainkeys yes, no
keyboard yes, no
ncore 1, 2, 4
I'm eventually going to borrow a device but hope to get a head start on things before the project start date so would be extremely grateful to hear of any workarounds other than those already attempted.

Environment
Android Studio 2.2.3
Windows 7 x64
Updates
I have removed and reinstalled SDK and Android Studio.
I am able to replicate this on 2 development machines (so far) so would be useful to discover if anyone else experiences this behaviour for this config.

Current AndroidStudio sample fails on phone due to runtime native library link error. Why?

Its on an HTC Aria, running 2.2 (API 8)
https://en.wikipedia.org/wiki/HTC_Aria
The aria is an armv6 device that supports opengles 2
If you open up the latest Android Studio (im working on windows 7), then import the HelloGL2 sample, then simply try to run it on the above device, it will fail as soon as it tries to make a call into the native library.
Here is the log:

This sample works on the 3 other devices i've tried (Galaxy s5, Galaxy J1, Nexus s)
The line: 'Unable to dlopen(/data/data/com.android.gl2jni/lib/libgl2jni.so): Cannot load library: link_image[1995]: failed to link libgl2jni.so' is probably key. I tried loading the library explicitly using system.loadlibrary, but the same problem happens on that call.
I think it might be something to do with the processor being armv6?
The sample is configured to do 'armeabi' though.

Camera of any emulator not working

Friends
I am facing this issue since so long but i am able to get any kind of solution to get working camera in emulator. I have gone through all the answer of the SO but none helped me uptill now.
If i create any emulator with any api but in none of my emulator camera application does not work. So i am not able to test any of the application which contains camera functionality. I guess may be its happening because of the hardware configuration of my system. But i am not sure about it.
I do not know why this issue occurs. Please help me to solve and find out the reason for the issue.
Here is the error which i get whenever i starts camera in emulator.

Below are the options which i get while i am trying to edit emulator.
Thanks.

I have resolved my issue by changing the emulators "Back Camera" property to Emulated as shown in screenshot.

Open Tools->Android->AVD Manager then click edit for your virtual device.Click Show Advanced Settings on your virtual device configuration window.Then camera settings field is turned on,select Emulated Front and Back.That is it.

There is no declaration about Camera in limitation of Emulator in doc.
You can Enable camera in Emulator.But emulator wont show a realtime camera regardless.
As of Android SDK version 14, the emulator supports webcams to simulate a camera:
General notes - Added webcam support to Android 4.0 or later platforms
to emulate rear-facing cameras when one webcam is present, and to
emulate both rear-facing and front-facing cameras when two webcams are
present. Webcam suport is for Windows and Linux only. Mac support will
come in a later release.

I'm using Android Studio 3.1.1 in ubuntu 16.04 and had the same issue.
So after couple of days googling, finally solved my problem by myself.
The Solution was:
Edit the AVD and set the Emulated Performance/Graphics from Automatic to Software - GLES 1.1.
Changed the SD Card size to 256 MB.
Set only one of camera (e.g. Front) to webcam0 and other one to none or emulated.
Hope this helps others with the same problem.

JUST DO THIS
use emulated in both Front and back and then chage sdcard size

From the android documentation:
Emulator Limitations
No support for camera/video capture
In other words, no, you cannot access or preview the camera in the emulator.

Android AVD emulator not running app, but device does? (OpenGL)

Hi I am trying to run some sample openGl code on an emulator. I am new to Android development. It crashes on the emulator but not my device, a Samsung Galaxy Note phone N7000.
The AVD settings I tried were:
Target: Android 4.1 - API Level 16

SD Card: 32 MiB
Skin: Built-in : WGA800

Just recreate or edit your emulator and be sure that under the hardware list you have
GPU Emulation set to Yes
