Android build crashes

[thegreatkoe]

Hi,

after adding react-native-fast-opengpg when i try to run npx react-native run-android the build fails with:

Execution failed for task ':react-native-fast-openpgp:generateJsonModelDebug'.
> java.lang.NullPointerException (no error message)

I already tried to run the build:

• with and without hermes enabled,
• with java 8 and java 11

I had the same issue, after hours of messing around trying to get it to work, I came across this similar Stack Overflow post: https://stackoverflow.com/questions/67120904/cannot-properly-link-c-project-with-gradle-exception-during-working-with-exte

In short, it appears the issue seems to be that this lib is incompatible with newer versions of CMake.

I now have it compiling on Android, here's what I did to get it working:

• Download the CMake v3.19.8 tar/zip file for your operating system from https://github.com/Kitware/CMake/releases/tag/v3.19.8 (for me on linux it was https://github.com/Kitware/CMake/releases/download/v3.19.8/cmake-3.19.8-Linux-x86_64.tar.gz).
• Extract it to somewhere safe on your computer
• In Android studio, open the file local.properties
• Add the line cmake.dir=/the/path/to/where/you/extracted/cmake
• Do a Gradle Sync in Android Studio
• Hit compile and it should work 🤞🏼 (it did for me)

@jerson I have no idea about CMake, but from this I assume something needs to be updated in the repo to work with newer versions of CMake
