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

Question

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

Answer 1

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.

Answer 2

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.

Answer 3

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