_DESCRIPTION = (
"""Fetches symbol files for Android official builds, need access to the storage.
Useful to symbolize crashes. You can find the version number and version code
in the bug reports or stack trace. Version number is commonly used Chrome
Version, like "93.0.4606.0" and version code is play store version code, a 9-10
digit number starting with branch number, 460601633. Module ID can be seen from
unsymbolized stack trace, a 32 character hex string in upper case. You need to
build dump_syms in your local output dir to use module ID matcher. In any
Android output directory with same arch (arm), build dump_syms by using
ninja -C out-android/Release dump_syms.
