Please add x86_64 version of vudroid.so

[montreux]

The absence of this version of the library can cause crashes on x86_64 android devices with java.lang.UnsatisfiedLinkError. I encountered this crash on a HUDL 2.

@JoanZapata, @montreux I just encountered the above mentioned issue with the emulator running the x86_64 system image and API level 23.

I created a new folder x86_64 in the lib folder:

and I put the x86 libvudroid.so. I compiled and run the app and here's the new error log:

Pretty close:

"/data/app/com.foobar.fooapp-2/lib/x86_64/libvudroid.so" is 32-bit instead of 64-bit

All I need now is the x86_64 lib version.

Any advice on where to find the x86_64 lib version and/or how to compile source?

Thanks.

[montreux]

I tried that too without success. The hack that worked for me was deleting the x86-64 libraries for the other dependencies. Then it successfully fell back to the 32 bit versions.

I'm afraid I don't know where to find a x86-64 version of libvudroid.so

@montreux I just gave a try to your approach although the result was sadly unsuccessful.

Thanks for the reply.

sorry， I did not encounter this problem， If I met and have a solution or way of thinking， I'll tell you in time

@montreux, @Sunycha

I downloaded vudroid source and compiled libraries for x86_64 and mips64 architectures. The source was compiled with Android NDK Revision 11b (March 2016) for Linux 64-bit (x86).

Here you'll find the files and the pull request: #191
