This patch adds a new directory named "android/" which contains
the following:
- A NDK build system module definition for the Google Breakpad
client library. This can be used by developers using the ndk-build
build system to more easily build and use the client library in
their own programs.
- A sample application demonstrating how to use the module,
as well as test that the library works properly during a
crash.
- A shell script (run-checks.sh) that will check everything
for you automatically, including:
- Rebuilding the host Google Breakpad host package with configure/make
- Rebuilding the Android client library with configure/make
- Rebuilding the Android client library and test program with ndk-build
- Running the crashing test program, extract minidump, dump symbols,
generate a stack trace and check that it has correct source file
locations.
For more details, run android/run-checks.sh --help-all
+ Updates to the README.ANDROID documentation.

Usage: $PROGNAME [options]
|
|
|
|
This script is used to check that your Google Breakpad source tree can
|
|
be properly built for Android, and that the client library and host tools
|
|
work properly together.
|
|
"
|
|
if [ "$HELP_ALL" ]; then
|
|
echo "\
|
|
In more details, this script will:
|
|
|
|
- Rebuild the host version of Google Breakpad in a temporary
|
|
directory (with the Auto-tools based build system).
|
|
|
|
- Rebuild the Android client library with the Google Breakpad build
|
|
system (using autotools/configure). This requires that you define
|
|
ANDROID_NDK_ROOT in your environment to point to a valid Android NDK
|
|
installation directory, or use the --ndk-dir=<path> option.
|
|
|
|
- Rebuild the Android client library and a test crashing program with the
|
|
Android NDK build system (ndk-build).
|
|
|
|
- Require an Android device connected to your machine, and the 'adb'
|
|
tool in your path. They are used to:
|
|
|
|
- Install and run a test crashing program.
|
|
- Extract the corresponding minidump from the device.
|
|
- Dump the symbols from the test program on the host with 'dump_syms'
|
|
- Generate a stack trace with 'minidump_stackwalk'
|
|
- Check the stack trace content for valid source file locations.
|
|
|
|
You can however skip this requirement and only test the builds by using
|
|
the --no-device flag.
|
|
|
|
By default, all generated files will be created in a temporary directory
|
|
that is removed when the script completion. If you want to inspect the
|
|
files, use the --no-cleanup option.
|
|
|
|
Finally, use --verbose to increase the verbosity level, this will help
|
|
you see which exact commands are being issues and their result. Use the
|
|
flag twice for even more output. Use --quiet to decrease verbosity
|
|
instead and run the script silently.
