This project can be used as a workaround by forging caller address. 10 | 11 | The basic idea is to simply set `dlopen`/`dlsym` as JNI functions, which are actually called by trampoline code in `libart.so` and can be used to trick the linker. 12 | 13 | In this way, neither `/proc/self/maps` file nor ELF parsing is needed, and hopefully symbol hash table could be utilized during resolution for faster symbol lookup. 14 | 15 | 16 | ## Setup 17 | 18 | The library is built with the new feature of Android Gradle Plugin for [native code dependency](https://developer.android.com/studio/build/native-dependencies), which would add [prefab](https://google.github.io/prefab/) modules into the `.aar` file. 19 | 20 | To use the library, first make sure that Android Gradle Plugin version 4.0+ is used. Then add the library as a dependency: 21 | 22 | ``` 23 | implementation 'io.github.rk700:dlfunc:0.1.1' 24 | ``` 25 | 26 | Put the following lines into the android block of the module's `build.gradle` file to enable prefab: 27 | 28 | ``` 29 | buildFeatures { 30 | prefab true 31 | } 32 | ``` 33 | 34 | In `CMakeLists.txt` file, add the following lines to expose the `dlfunc` library to native code: 35 | 36 | ``` 37 | find_package(dlfunc REQUIRED CONFIG) 38 | 39 | target_link_libraries( # Specifies the target library. 40 | app 41 | 42 | # Links the dlfunc library to the target library. 43 | dlfunc::dlfunc 44 | ) 45 | ``` 46 | 47 | Android NDK [sample for prefab](https://github.com/android/ndk-samples/tree/master/prefab/prefab-dependency) also provides an example for importing a prefab library. 48 | 49 | ## Usage 50 | 51 | First, include the header file `dlfunc.h` in the native code: 52 | 53 | ```c 54 | #include "dlfunc.h" 55 | ``` 56 | 57 | Then run the function `dlfunc_init` for initialization. 58 | 59 | ```c 60 | if(dlfunc_init(env) != JNI_OK) { 61 | LOGE("dlfunc init failed"); 62 | return; 63 | } 64 | ``` 65 | 66 | Now just call `dlfunc_dlopen` and `dlfunc_dlsym` simply as calling `dlopen`/`dlsym`, except that the `JNIEnv *env` is passed in as the first argument: 67 | 68 | ```c 69 | void *handle = dlfunc_dlopen(env, "libart.so", RTLD_LAZY); 70 | LOGI("libart handle is %p", handle); 71 | if(handle != NULL) { 72 | void *ptr = dlfunc_dlsym(env, handle, "MterpCheckBefore"); 73 | LOGI("MterpCheckBefore is at %p", ptr); 74 | } 75 | ``` 76 | ## License 77 | 78 | `dlfunc` is distributed under Apache License 2.0. 79 | -------------------------------------------------------------------------------- /build.gradle: -------------------------------------------------------------------------------- 1 | // Top-level build file where you can add configuration options common to all sub-projects/modules. 2 | buildscript { 3 | repositories { 4 | google() 5 | jcenter() 6 | } 7 | dependencies { 8 | classpath "com.android.tools.build:gradle:4.1.1" 9 | 10 | // NOTE: Do not place your application dependencies here; they belong 11 | // in the individual module build.gradle files 12 | } 13 | } 14 | 15 | allprojects { 16 | repositories { 17 | google() 18 | jcenter() 19 | } 20 | } 21 | 22 | task clean(type: Delete) { 23 | delete rootProject.buildDir 24 | } -------------------------------------------------------------------------------- /dlfunc/.gitignore: -------------------------------------------------------------------------------- 1 | /build -------------------------------------------------------------------------------- /dlfunc/CMakeLists.txt: -------------------------------------------------------------------------------- 1 | # Sets the minimum version of CMake required to build your native library. 2 | # This ensures that a certain set of CMake features is available to 3 | # your build. 4 | 5 | cmake_minimum_required(VERSION 3.4.1) 6 | 7 | # Specifies a library name, specifies whether the library is STATIC or 8 | # SHARED, and provides relative paths to the source code.
