:green_circle: (SOLVED) Failed to compile for arm64-v8a Android with Docker

[decryptable]

Is there something in my Dockerfile.Android configuration?

docker run -e FRIDA_CODE_FILE=/script.js -v ${pwd}/target:/injectionforge/target -v ${pwd}/myscript.js:/script.js injectionforge-android

---

My current customised Dockerfile.Android configuration:

FROM ubuntu

The following warnings were emitted during compilation:

[dzervas]

as the log suggests, the rust toolchain for the target is missing. try to slim down the dockerfile to build only for aarch64-linux-android and see what's wrong

Solved! I used @cross-rs/cross as an alternative.
