OpenGl renderer on Android

I am trying to make a simple renderer with OpenGL2.0, made up only of a main activity, surface view, and renderer file. Whenever I run it on an avd, the screen turns black and says the program has encountered a problem. Here is the logcat
08-04 03:55:59.722: D/libEGL(6287): Emulator without GPU support detected. Fallback to software renderer.

Can the problem be recognized from this or should I provide code as well?

InApp Billing: Caller uid is different

I'm trying to implement InApp billing. When I open the Play Store on my HTC Desire running (custom rom, rooted) GB, I get a message "An error occured, please try again". In the logcat, it says this:

On my Asus TF101 running (custom rom, rooted) ICS, it does work.
On an HTC One V running stock ICS, it does work.
On an HTC Legend running (custom rom, rooted) GB, it does work.
So only on my HTC Desire it doesn't, work, which, frankly, is my main device. I've tried to reset the device to factory defaults, but that didn't help.
What's happening here?

Apparently, the Play Store on my Desire didn't update automatically. It was running 3.5.x, I had to manually push 3.5.17 for it to work.

Adding addmob adds to main.xml crashes my app

Let me start by saying that this app was working fine the day before. I have restarted the pc, removed the project and added a previous version of the project and it keeps crashing. If i remove this from main.xml which gets loaded from the mainactivity the app does not crash. If i have this in the main.xml :
<com.google.ads.AdView
android:id="#+id/adView"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
ads:adSize="BANNER"
ads:adUnitId="a14ee1ad68dcbdb"
ads:loadAdOnCreate="true" />
the app crashes. If i run the app and this code is not in the main.xml file but in other xml files the app works fine and it will show adds from other activities.
I tried removing all the code in the xml file and just have the above admob adds in there and it still crashed. I was thinking about uninstalling eclipse and installing it again???
Any ideas????

Looks like you're trying to debug the app, and it's hanging on debug. Do you get any more relevant logs if you try to just run it?
Also, have you updated to r17 of the Android Tools by any chance? r17 of the tools force you to place the SDK in the libs/ folder of your project.

Are you sure you have stepped through a tutorial properly and added the permissions and imported the SDK?
Try stepping through this guide from the beginning:
https://developers.google.com/mobile-ads-sdk/docs/android/fundamentals
Cleaning the project in Eclipse sometimes solves some problems.

I had a very similar bizarre issue with Admob recently after a fresh install of Eclipse. After hours of looking into why, it ended up being my build order in the project preferences. I set the Google AdMob jar to the top, cleaned the project and all my issues were resolved.
The logcat text you have pasted does not give any error information. Can you paste the logcat text from the point of failure, generally you can see the communications with AdMob in here.
May help, just a thought.

Android Mono '/data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so' not found

I wonder if you can help me with this error.
I am running a fresh fully updated install of windows 7 with
Visual studio 2010 Professional in trial mode.
In Visual Studio I create a new OpenGl Mono for Android Application
using the built in template.
I compile and run the application.
The emulator boots (I am running API_8) EMU.
The application starts and then aborts.
(In the emulator I get a black screen which quickly closes.)
Same thing happens if I do similar using the Mono Develop IDE
and or the other templates.
Here is a dump of the error message (I cannot find much info on google)
It looks like the error is related to the load library fail.
Thanks

The issue is from the newer versions of mono where libmonosgen-2.0 does not get installed automatically. The path that you will see in which it fails is actually a simlink for the library. What you have to do is manually or through a non-mono apk, create the following:
A folder with your package name in /data/app-lib/
in the folder you will have to push the libmonosgen-2.0.so (and libmonodroid.so if needed)
After this is done you have to navigate to data/data/your.package.name and create a simlink from lib -> the folder you created previously. the command to use is ln -s.
I have noticed that in some cases the simlink exists, but is pointing to a false location.
I had to do this manually and it would not survive a factory reset. A colleugue of mine actually did this the non-mono apk path which does everything for him when ever the provisioning app executes on first launch.

Try going to the project properties and turn off "fast deployment". Then manually remove your app from the emu/device, and try again.

Another possibility is that you don't have enough free space on your device. The problem isn't in your package (OpenGLApplication1), the problem is from installing the Mono.Android.DebugRuntime package, as /data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so doesn't exist.
I would suggest looking through the adb logcat log, and see if something like the following is present:
W/NativeHelper( 98): Failed to cache package shared libs
W/NativeHelper( 98): java.io.IOException: Couldn't create cached binary /data/data/Mono.Android.DebugRuntime/lib/libmonosgen-2.0.so in /data/data/Mono.Android.DebugRuntime/lib
W/NativeHelper( 98): at com.android.internal.content.NativeLibraryHelper.copyNativeBinaryLI(NativeLibraryHelper.java:289)
If messages like the above are present, remove the Mono.Android.DebugRuntime package (adb uninstall Mono.Android.DebugRuntime), remove some extra apps from your device (to free up space), and try re-installing your app from the IDE.

Ok, looks like I was using the wrong constructor. I've made eclipse auto generate the code and it created this:
public LoginTest(String pkg, Class<Login> activityClass) {
super(pkg, Login.class);
}
However, upon changing it to this:
public LoginTest() {
super("pkg_name", Login.class);
}
it works fine. I'm not sure why, though, so if anyone can provide an explanation, I'd be happy to accept that as the answer. For everyone else encountering this error, all the online discussion around this seems to indicate that there's some error in your constructor.

i have removed the argument and now this is working try it.
public class LoginTest extends ActivityInstrumentationTestCase2<Login> {
Activity mActivity;
EditText mLoginTxt;
EditText mPwdTxt;
Button mLoginBtn;
Button mClearBtn;
public LoginTest() {
super("pkg_name", Login.class);
}
#Override
public void setUp() throws Exception {
super.setUp();
}
public void testPreconditions() {
}
public void testClear() {
assertTrue(true);
}
