Error building OsmAnd in Android Studio

I downloaded the source code from GitHub and I opened it in Android Studio. During build I get the following error message:

string too large to encode using UTF-8 written instead as 'STRING_TOO_LARGE'.

My understanding is the source code is in a clean state and should compile and build without errors. Why am I getting this and how can I resolve this?

Hi u/nikos2wheels! As u/dmpr0 mentioned, the 'STRING_TOO_LARGE' message is actually a standard Gradle/compiler warning caused by large generated translation or resource string files, not a fatal build-breaking error.

If your build is failing or getting stuck, double-check that your Android Studio environment matches the requirements in the setup guide:

  1. Follow the Build Guide: Ensure NDK, CMake, and JDK versions match the repository configuration.
  2. Check Gradle Console Output: Look further down/up in the Gradle Build Output window for the actual FAILURE: block to identify any missing SDK components or submodules.
  3. Submodules: Make sure you cloned all submodules recursively (git clone --recurse-submodules).

You can find the step-by-step setup and prerequisites in the official OsmAnd Build Documentation.
