"""Dump shared library information from an APK file.
|
||
|
|
|
||
|
|
This script is used to dump which *uncompressed* native shared libraries an
|
||
|
|
APK contains, as well as their position within the file. This is mostly useful
|
||
|
|
to diagnose logcat and tombstone symbolization issues when the libraries are
|
||
|
|
loaded directly from the APK at runtime.
|
||
|
|
|
||
|
|
The default format will print one line per uncompressed shared library with the
|
||
|
|
following format:
|
||
|
|
|
||
|
|
0x<start-offset> 0x<end-offset> 0x<file-size> <file-path>
|
||
|
|
|
||
|
|
The --format=python option can be used to dump the same information that is
|
||
|
|
easy to use in a Python script, e.g. with a line like:
|
||
|
|
|
||
|
|
(0x<start-offset>, 0x<end-offset>, 0x<file-size>, <file-path>),
