ModernLinker issue loading SO files in runtime

[ayde...@gmail.com]

Hi all! We used external library-SDK with so files in our project and there were no problems with it. The application worked as expected and had no problems but recently we started to receive lots of crashes with unclear logs. Digging deeper we found that on application creation exception occured when loading native libraries. Log:

The crash is completely random. happens in 30% of times on some rare devices. Using LegacyLinker fixes the issue but we hope to find the issue and leave ModernLinker as is. Any help is appreciated

Not sure what your setup is, but non-determinism is a little puzzling to me.

We are planning to remove the ModernLinker in Chromium soon: https://goo.gl/kWnHYr (link to googledoc on chromium.org), in favor of the LegacyLinker (yes .. as intuitive as that). I expect this to be a path of a few surprises, likely to be reverted a few more times.

If you do not need RELRO sharing/packing and loading from the APK, then you can use System.loadLibrary(), this is the path of least surprise.

Generally we do not support any external libraries that might want to provide parts of Chromium on a side. On Android the supported alternatives are: CustomTabs, WebView, Cronet.

I want to reopen an old topic. I'm getting a similar error in an older Chromium version(64.0.3246.0). Are there any suggestions?
