APK的Native库使用Address Sanitizer分析内存异常访问(Android.bp)

官网文档介绍了如何使能Address Sanitizer和运行时控制它的行为

本文接下来主要是对官网的补充:

1、Android.bp构建Native代码时如何使能Address Sanitizer功能

cc_library_shared {
name: "libnative_test",

cflags: [
    "-fno-omit-frame-pointer",
    "-O0",
],

sanitize: {
    address: true;//使能Address Sanitizer
    hwaddress: true;//使能HW Address Sanitizer
},
}

cflags增加"-fno-omit-frame-pointer"和"-O0"选项，为了让打印的栈信息更清晰

address和hwaddress字段不能一起使能，

2、AndroidManifest.xml中android:extractNativeLibs=true如果不配置采用默认值可能会出现APK
