crashed on startup on Asus K010 Intel CPU

[zaferaydn]

Hello; I downloaded the lastest repository as a zip file. I opened the project Imsdroid with Android Studio. I successfully build and install the apk on my tablet. But application fails on start up. Android reports a messagebox saying "IMSDroid has stopped".

My tablet is Asus K010 which has intel atom cpu(I guess). Doesn't Imsdroid run on intel CPU? Is there any known issue?

I attach the logcat output where I think the error happens:

edit: When i disable neon library, it works! In NgnEngine.initialize2 function I commented NgnApplication.isCpuNeon() block. So it wont load neon library. At this case it work properly. But disabling neon library usage can have some sideffects? Any real solution?

I realised that android os loads armv7 libraries insead of x86. I guess there is a feature in android os called houdini that similuates armv7 libraries as x86. But somehow houdini fails while trying to simulate neon library of libtinyWRAP_neon library.

I researched alittle bit, and i found why android os tries to simulate armv7 libraries with houdini insead of using x86 libraries directly. Because there are missing library files in x86 folder(libtinyWRAP_neon and libutils_armv5te are only in armeabi-v7a folder), android thinks that there is missing libraries in x86 so it tries to loads armv7 libraries insead.

I made a workaround by adding fake libraries named libtinyWRAP_neon and libutils_armv5 (with 15 bytes fakes content for example) into the x86 and armeabi folder where these libraries missed. So in the end, all folders(armeabi, armeabi-v7a and x86) have same number of libraries. Then android decided to load x86 libraries.

I also needed to add following line in initialize2 function:

File refFile = new File(String.format("%s/%s", NgnEngine.LIBS_FOLDER, "libutils_armv5te.so")); boolean haveLibUtils = refFile.exists() && refFile.length() > 0;
