App crashes at startup - Android 6.0.1

[vindberg]

I have installed the Signer on an older phone (Nexus 5) and it crashes instantly when opening the app. A white screen appears shortly and then the "Parity signer has stopped" message.

Will it ever work on Android 6.01?

Thanks.

Hi, it is compatible with Android 6.01, current crash problem on some devices is caused by Rust bindings on v4.4, we are investigating the crashes now, please use v4.3 now.

Thanks for the reply. When do you expect a fix?

I will try the other version if I can get it installed as a pack.

I have a Nexus 5 and can reproduce the crash.

It seems to be a rust library building problem because Unwind is not linked correctly in ARM32 architecuture according to the discussion, and NDK docs.

It seems we need to add the following flags when building ARM32 in the build script

-Wl,--exclude-libs,libgcc.a -Wl,--exclude-libs,libunwind.a

but I am not sure, @tomaka do you have any ideas where to add these flags?

#675 current solve the problem, but I use a fallback solution, a optimized way to solve it still need to fix building with prebuilt NDK libraries.
