对我也不起作用,我正在尝试在带有 Android 11 的 Google Pixel 2 XL 上测试 GWP-Asan。
更新:由于某种原因,当 Android Studio 调试器设置为 Dual 时,应用程序启动并正常运行。在没有附加调试器的情况下运行,使 GWP Asan 工作,此外,您可能希望使用标签“DEBUG”过滤 logcat,因为它是打印日志的地方
使用 Android Studio 中的 JNI 创建 Android 应用,build.gradle 如下所示:
plugins {
id 'com.android.application'
}
android {
compileSdkVersion 30
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "com.example.gwpadresssanitizer"
minSdkVersion 16
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags ""
}
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
externalNativeBuild {
cmake {
path "src/main/cpp/CMakeLists.txt"
version "3.10.2"
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}
清单看起来像这样:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gwpadresssanitizer">
<application

使用代码:
jstring native_get_string(JNIEnv* env) {
std::string s = "Hellooooooooooooooo ";
std::string_view sv = s + "World\n";
// BUG: Use-after-free. `sv` holds a dangling reference to the ephemeral

// use-after-free.
return env->NewStringUTF(sv.data());
}
extern "C" JNIEXPORT jstring JNICALL

for (unsigned i = 0; i < 0x10000; ++i) {
return_string = native_get_string(env);
}
return reinterpret_cast<jstring>(env->NewGlobalRef(return_string));
}
