A wrapper around ProGuard's ReTrace tool, which:

  1. Updates the regular expression used to identify stack lines, and
  2. Streams its output.

The second point here is what allows you to run:

adb logcat | build/android/stacktrace/ out/Default/apks/ChromePublic.apk.mapping

And have it actually show output without logcat terminating.

Update Instructions:

ninja -C out/Release java_deobfuscate_java
cp out/Release/ build/android/stacktrace

Extracts Breakpad microdumps from a log file and uses stackwalker to symbolize them.

Fetches Crashpad dumps from a given device, walks and symbolizes the stacks.
