简介
breakpad是由谷歌提供的跨平台的异常捕获分析工具，目前支持Mac、Linux、Windows平台，主要包括三大部分：
- client，以library的形式内置在你的应用中，当崩溃发生时写 minidump文件
- symbol dumper, 读取由编译器生成的调试信息（debugging information），并生成 symbol file
- processor， 读取 minidump文件 和 symbol file ，生成可读的c/c++ Stack trace.
编译
下载breakpad源码
git colne https://codeload.github.com/google/breakpad/zip/master
编译
./configure
make
make install
编译完成后会生成minidump_stackwalk执行程序，是用来转换dmp文件的
Android中使用breakpad
- 把breakpad目录下src下源码到Androidstudio工程的cpp中
- 配置cmake
cmake_minimum_required(VERSION 3.4.1)
set(BREAKPAD_ROOT ${CMAKE_CURRENT_SOURCE_DIR})
include_directories(${BREAKPAD_ROOT}/src ${BREAKPAD_ROOT}/src/common/android/include)
file(GLOB BREAKPAD_SOURCES_COMMON

)
file(GLOB BREAKPAD_ASM_SOURCE ${BREAKPAD_ROOT}/src/common/android/breakpad_getcontext.S
)
set_source_files_properties(${BREAKPAD_ASM_SOURCE} PROPERTIES LANGUAGE C)
add_library(breakpad STATIC ${BREAKPAD_SOURCES_COMMON} ${BREAKPAD_ASM_SOURCE})
target_link_libraries(breakpad log)
- 需要写个初始化方法
JNIEXPORT void JNICALL
Java_com_sample_breakpad_BreakpadInit_initBreakpadNative(JNIEnv *env, jclass type, jstring path_) {
const char *path = env->GetStringUTFChars(path_, 0);
google_breakpad::MinidumpDescriptor descriptor(path);
static google_breakpad::ExceptionHandler eh(descriptor, NULL, DumpCallback, NULL, true, -1);
env->ReleaseStringUTFChars(path_, path);
}
//crash时回调函数
bool DumpCallback(const google_breakpad::MinidumpDescriptor &descriptor,
void *context,
bool succeeded) {
ALOGD("Dump path: %s\n", descriptor.path());
return succeeded;
}
- 写测试程序
//人为写个空指针
void Crash() {
int *test=NULL;
*test=1;
}
当native crash时会生成1f1e4c88-6a3c-4827-ee3626b2-4f74ccee.dmp文件，直接打开
