+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, x86 and MIPS based Android systems.
+This release requires NDK release r11c or higher.
+
+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++
+
+
+I.2. 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 https://chromium.googlesource.com/breakpad/breakpad/+/master/docs/linux_starter_guide.md
+
+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.
+
+For more details, please run:
+
+ android/run-checks.sh --help-all
