I write an extension which will compile with a third party .so file in android.I put the .so to lib/armv7-android folder, but it encounter a build error:

I’m not familiar with Crasheye but looks like it is a [dynamic lib](http://www.testplus.us/docs/crasheye/androidndkuse#overview-android-ndk) which require jar file in lib folder. As far as I know Defold doesn’t support dynamic libs. Maybe you can use this one: [http://www.testplus.us/docs/crasheye/androidsdkuse#overview-android-sdk](http://www.testplus.us/docs/crasheye/androidsdkuse#overview-android-sdk)

I think you need to add the library to the [`dynamicLibs` field](https://forum.defold.com/t/defold-1-2-141-has-been-released/33996) in your extension manifest to be able to link against it. Otherwise, you might still be able to use the library with `dlopen() / dlsym()`, but that’s a hassle. Also, you’ll need to place the same shared library in the `res/armv7-android/lib/armeabi-v7a/` directory, so that it’s bundled in the APK.

Yes, currently, the usage of .so files isn’t great.  
We have a ticket for it, but other extension related things have taken priority.
