Problem with Android application that contain native libraries for multiple platforms

Problem with Android application that contain native libraries for multiple platforms

Hi Guys,

I stuck with one problem and really hope somebody can help me to shed some light on this...

My Android application contains native libraries for the next platforms:




It works fine on any ARM based device and uses corresponding armeabi libraries.

I tested it also on Intel based x86 Samsung Galaxy Tab and it also works fine and loads corresponding x86 library.

Today I tested it on ASUS Phonepad and discovered that instead of loading x86 library it prefers to load armeabi instead. If I remove armeabi libraries from APK it does load x86 library and works fine but I need to have all three sets of libraries for all platforms.

From the system log I can also see that system tries to use houdini library to translate my ARM based native library into x86 (which doesn't make any sense as I have x86 based library provided):

07-25 12:37:55.011    9207-9220/net.myapp D/houdini﹕ [9220] Loading library(version: RELEASE)... successfully.

So my question is, what am I doing wrong so it doesn't load x86 based library? Should I add some other ABI into the APK?

My cpuinfo is as follows:

because in certain markets, many developers have a broken set of x86 libraries (mainly missing some libs for x86), a workaround has been implemented on some devices to avoid these apps to crash: by falling back to the arm libs.

if you have different names and count of libs depending on the architecture, this workaround can cause the issue you're encountering.

Device software updates should fix these side-effects as this workaround is being improved, but in the meantime, if you want to support these devices, I can only recommend having the same set of libs names and numbers for each architectures to make it work.

Hi Xavier,

Thank you for your response.

I can confirm that making sure that both targets contain the same sets of native libraries makes it choose x86 based libraries which fixes the issue in my case. In terms of my application it means that I have to include some dummy libraries in my x86 target just for the sake of making it matching with what ARM target provides but the fact the this will be resolved in one of the upcoming release is the great news.

Thanks again for your help!
