This patch updates README.ANDROID, since the client library now supports directly generating a minidump without raising a signal, and that it builds and runs fine on Android/x86. + Formatting fixes in minidump_writer_unittest.cc Review URL: https://breakpad.appspot.com/446002 git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@1026 4c0a9323-5329-0410-9bdc-e9ce6186880e

Google Breakpad for Android
|
|
===========================
|
|
|
|
This document explains how to use the Google Breakpad client library
|
|
on Android, and later generate valid stack traces from the minidumps
|
|
it generates.
|
|
|
|
This release supports ARM and x86 based Android systems. MIPS is not
|
|
currently supported by Breakpad.
|
|
|
|
I. Building the client library:
|
|
===============================
|
|
|
|
The Android client is built as a static library that you can
|
|
link into your own Android native code. There are two ways to
|
|
build it:
|
|
|
|
I.1. Building with ndk-build:
|
|
-----------------------------
|
|
|
|
If you're using the ndk-build build system, you can follow
|
|
these simple steps:
|
|
|
|
1/ Include android/google_breakpad/Android.mk from your own
|
|
project's Android.mk
|
|
|
|
This can be done either directly, or using ndk-build's
|
|
import-module feature.
|
|
|
|
2/ Link the library to one of your modules by using:
|
|
|
|
LOCAL_STATIC_LIBRARIES += breakpad_client
|
|
|
|
NOTE: The client library requires a C++ STL implementation,
|
|
which you can select with APP_STL in your Application.mk
|
|
|
|
It has been tested succesfully with both STLport and GNU libstdc++
|
|
|
|
|
|
II.1. Building with a standalone Android toolchain:
|
|
---------------------------------------------------
|
|
|
|
All you need to do is configure your build with the right 'host'
|
|
value, and disable the processor and tools, as in:
|
|
|
|
$GOOGLE_BREAKPAD_PATH/configure --host=arm-linux-androideabi \
|
|
--disable-processor \
|
|
--disable-tools
|
|
make -j4
|
|
|
|
The library will be under src/client/linux/libbreakpad_client.a
|
|
|
|
You can also use 'make check' to run the test suite on a connected
|
|
Android device. This requires the Android 'adb' tool to be in your
|
|
path.
|
|
|
|
II. Using the client library in Android:
|
|
========================================
|
|
|
|
The usage instructions are very similar to the Linux ones that are
|
|
found at http://code.google.com/p/google-breakpad/wiki/LinuxStarterGuide
|
|
|
|
1/ You need to include "client/linux/handler/exception_handler.h" from a C++
|
|
source file.
|
|
|
|
2/ If you're not using ndk-build, you also need to:
|
|
|
|
- add the following to your compiler include search paths:
|
|
$GOOGLE_BREAKPAD_PATH/src
|
|
$GOOGLE_BREAKPAD_PATH/src/common/android/include
|
|
|
|
- add -llog to your linker flags
|
|
|
|
Note that ndk-build does that for your automatically.
|
|
|
|
3/ Keep in mind that there is no /tmp directory on Android.
|
|
|
|
If you use the library from a regular Android applications, specify a
|
|
path under your app-specific storage directory. An alternative is to
|
|
store them on the SDCard, but this requires a specific permission.
|
|
|
|
For a concrete example, see the sample test application under
|
|
android/sample_app. See its README for more information.
|
|
|
|
|
|
III. Getting a stack trace on the host:
|
|
=======================================
|
|
|
|
This process is similar to other platforms, but here's a quick example:
|
|
|
|
1/ Retrieve the minidumps on your development machine.
|
|
|
|
2/ Dump the symbols for your native libraries with the 'dump_syms' tool.
|
|
This first requires building the host version of Google Breakpad, then
|
|
calling:
|
|
|
|
dump_syms $PROJECT_PATH/obj/local/$ABI/libfoo.so > libfoo.so.sym
|
|
|
|
3/ Create the symbol directory hierarchy.
|
|
|
|
The first line of the generated libfoo.so.sym will have a "MODULE"
|
|
entry that carries a hexadecimal version number, e.g.:
|
|
|
|
MODULE Linux arm D51B4A5504974FA6ECC1869CAEE3603B0 test_google_breakpad
|
|
|
|
Note: The second field could be either 'Linux' or 'Android'.
|
|
|
|
Extract the version number, and a 'symbol' directory, for example:
|
|
|
|
$PROJECT_PATH/symbols/libfoo.so/$VERSION/
|
|
|
|
Copy/Move your libfoo.sym file there.
|
|
|
|
4/ Invoke minidump_stackwalk to create the stack trace:
|
|
|
|
minidump_stackwalk $MINIDUMP_FILE $PROJECT_PATH/symbols
|
|
|
|
Note that various helper scripts can be found on the web to automate these
|
|
steps.
|
|
|
|
IV. Verifying the Android build library:
|
|
========================================
|
|
|
|
If you modify Google Breakpad and want to check that it still works correctly
|
|
on Android, please run the android/run-checks.sh script which will do all
|
|
necessary verifications for you. This includes:
|
|
|
|
- Rebuilding the full host binaries.
|
|
- Rebuilding the full Android binaries with configure/make.
|
|
- Rebuilding the client library unit tests, and running them on a device.
|
|
- Rebuilding the client library with ndk-build.
|
|
- Building, installing and running a test crasher program on a device.
|
|
- Extracting the corresponding minidump, dumping the test program symbols
|
|
and generating a stack trace.
|
|
- Checking the generated stack trace for valid source locations.
|
|
|
|
