I am first time to use Adroid App within Visual studio 2015 community, I just created a "Hello world" app by default wihthout any coding.

after by selecting AVD_GalaxyNexus_toolsForApacheCordova(Android 4.4-API19),then
then I press F5 to debug it.

after building, then for debugging, it gives the output:
Hide Copy Code
Android application is debugging.
Couldn't connect to logcat, GetProcessId returned: 0

I have searched internet by trying different approaches, none helps so far.

then I changed the AVD to "Xamarin_Android_API_15(Android 4.03-API 15)", then for debuging, it gives the output which contains the following message

AOT module 'Mono.Android.dll.so' not found: Cannot load library: load_library[1091]: Library '/data/data/App5.App5/lib/libaot-Mono.Android.dll.so' not found

Can anyone give me a hint on it?

thank you very much for your help!!

What I have tried:

I have searched internet and tried changing the properties,e.g by unchecking the "use fast deployment" and so on. it does not work.

The message is quite clear, a library file is missing. You need to check your installation to ensure you have added the correct library sets for the version you are building for.

thanks! You are right. but the strange thing is that the installation is automatic and did not give any errors, I have also updated the install several times. If I check and install manually these lib, whare should these .dll files be located? no any idea.

The error message tells you where the system is looking for the file. Are you sure it is not stored somewhere else, and you just need to tell Visual Studio where to look?

Seraph_summer 10-Apr-16 10:58am

no, no idea at all. I can not find the directory /data/data/App5.App5/lib/.
I do feel strange, based on Xamarin website, once everything is installed. it should not give such errors. I found further during my installation of Xamarin, it gives some exceptions in the log, but I am not sure whether these exceptions cause such problems. but by uninstall and install again does not help either. by the way, have you used Visual studio commnity 2015 with Xamarin?

Richard MacCutchan 10-Apr-16 11:42am

Sorry, I have not used Xamarin so I am not sure. I think the /data/data directories are part of the Android runtime, when does this message appear - at build time or run time?

Seraph_summer 10-Apr-16 11:59am

built has been done successfully, then in debug run time

Then it looks like part of your emulator has not been setup correctly. As I said, I have not used Xamarin, so I am afraid the I am out of suggestions.

I have made different emulator setting of properties with different suggestions from internet, none of them change the situations. I will resintall my PC system and re-install everthing to see anyhthing change.
thank you for your help.

That seems much too extreme. Since this is a runtime issue it is more likely that your app has not built correctly.

I have even a feeling that this is Microsoft intention,haha.
Visual studio 2015 Community is quite complicated and the installation met quite often problems, I have started the installation from yesterday till now, it still has not finished. I think this may be yet another reason why lot of people do not like use Visual studio. I have never met so many problems in using softwares.

Seraph_summer 11-Apr-16 15:39pm

I am using Windows 7, windows 8 and 10 may have less problems.

Seraph_summer 13-Apr-16 16:17pm

finally, I sovled the problem. it seems the problems I seen before were not actually the problems. I seems for the first time, I have to click the screen then it will show the app. after that, I do not need to click the screen anymore. I have met several times problems in installing,it works finally. thank you for your help!
