Stackwall is a static tool that takes your StackOverflowError and APK and finds out which parts of your application
are using the most stack space.
You will need a Java11 or higher JVM to run Stackwall. Stackwall currently has no releases, so you'll need to build it yourself. This situation will hopefully improve soon.
- Clone the repository
./gradlew assemble- Unpack the archive file in
build/distributions - Run
./bin/stackwall <application.apk> <stackoverflow.txt>
StackOverflow files are simply plain text files containing the stack-trace of the StackOverflowError your are looking
to analise. This is most typically in the standard Java format:
java.lang.StackOverflowError

Stackwall should be able to read most StackOverflowError traces (plain, ADB logs, etc), if you find a variant that
isn't understood, please open a Pull Request or log an Issue and be sure to include a test and full example.
Stackwall is still in a very early phase of development, these are major outstanding issues that need to be addressed:
- build / test / release process
- an index of platform methods to count against
- verify and improve the accuracy of the output (currently it's a best-guess)
- command-line options
- more test coverage
