(Alleviate crashes caused by insufficient virtual memory)` 6 | 7 | 一行代码解决 Android 32位应用因虚拟内存不足导致的 libc:abort(signal 6) 8 | 9 | ## 一、背景 10 | 目前国内的 Android App 大多数还是32位架构，仅提供了 arm-v7a 的动态链接库，市面上大多数手机都是64位的 CPU，App 通常都运行在兼容模式下，可以使用完整的 4GB 虚拟内存，但是国内应用一般都是集万千功能于一身，随着业务越来越复杂(内置webview、小程序、高清大图、短视频等等)，以及部分内存泄漏，4GB 的内存越来越不够用了。 11 | 12 | 从去年(2020)开始，各大头部应用的 Native Crash 开始暴增，通常 Top1 都是 `libc:abort`，通过上报的 maps 可见，虚拟内存地址空间大部分接近了 4GB，console logs 中也有大量的 `GL Errors: Out of memory(12)`。 13 | 14 | 针对此问题，一般首先能想到的就是排查内存泄漏问题，但往往收效甚微，多半是因为随着业务的发展，确实是需要这么多虚拟内存。诚然通过升级64位架构可以把地址空间上限扩充到512GB，但是因为各种原因(包大小、维护成本等等)，目前大部分应用尚未完成升级，所以在这里提供一种新的思路。 15 | 16 | (还是推荐大家尽快把自己的应用升级到64位架构哦~ 至少是双ABI架构，32位版本中可以继续保留 Patrons 用于提升存量用户的体验。) 17 | 18 | ## 二、原理 19 | 通过一系列技术手段实现运行期间动态调整`Region Space`预分配的地址空间，释放出最多`900MB`(根据实际情况调整参数)虚拟内存给到 libc:malloc，增加了接近30%的地址上限，大幅度给应用续命。 20 | 21 | 详细介绍：[阿里开源 Patrons：大型 32 位 Android 应用稳定性提升 50% 的“黑科技”](https://www.infoq.cn/article/bvbf3iwjztvem4szamvw) 22 | 23 | ## 三、使用方式 24 | 编译`patrons`模块 or 使用以下中心仓库的坐标，主工程依赖该模块产物，在合适的时机进行初始化： 25 | 26 | ```groovy 27 | repositories { 28 | mavenCentral() 29 | } 30 | dependencies { 31 | implementation 'com.alibaba:patrons:1.1.0' 32 | } 33 | ``` 34 | 35 | ```java 36 | com.alibaba.android.patronus.Patrons.init(context, null); 37 | ``` 38 | 39 | ##### [→ 测试 Demo 下载](https://github.com/alibaba/Patrons/blob/develop/demo/patrons-demo-1.1.0.apk) 40 | 41 | ## 四、Q & A 42 | 43 | 1. SDK 本身会带来多少接入成本(包大小、稳定性)：包大小增加20k左右，可以忽略不计；关键逻辑中会有多层保护，不会引发新的崩溃。 44 | 45 | 2. SDK 兼容性怎么样：在 Android 8、8.1、9、10、11、12 共 6 个主流版本生效，覆盖率接近 99.9%。在未兼容机型中不会生效，亦不会产生新的崩溃。 46 | 47 | 3. 使用后就能根治 Abort 么：肯定不能，因为 Abort 的成因很多，虽然32位应用多半是因为虚拟内存不足，但是也可能存在其他问题，适配性还是要具体情况具体分析。 -------------------------------------------------------------------------------- /app/proguard-rules.pro: -------------------------------------------------------------------------------- 1 | # Add project specific ProGuard rules here. 2 | # You can control the set of applied configuration files using the 3 | # proguardFiles setting in build.gradle. 4 | # 5 | # For more details, see 6 | # http://developer.android.com/guide/developing/tools/proguard.html 7 | 8 | # If your project uses WebView with JS, uncomment the following 9 | # and specify the fully qualified class name to the JavaScript interface 10 | # class: 11 | #-keepclassmembers class fqcn.of.javascript.interface.for.webview { 12 | # public *; 13 | #} 14 | 15 | # Uncomment this to preserve the line number information for 16 | # debugging stack traces. 17 | #-keepattributes SourceFile,LineNumberTable 18 | 19 | # If you keep the line number information, uncomment this to 20 | # hide the original source file name. 21 | #-renamesourcefileattribute SourceFile 22 | 23 | -optimizationpasses 1 24 | -optimizations code/removal/simple,code/removal/advanced,code/removal/variable,code/removal/exception,code/simplification/branch,code/simplification/field,code/simplification/cast,code/simplification/arithmetic,code/simplification/variable 25 | #-optimizations code/removal/simple,code/removal/advanced,method/removal/parameter,method/inlining/short,method/inlining/tailrecursion 26 | # ignoring warnings, that gets the scala app to work, but is a bit dangerous... 27 | -ignorewarnings 28 | -target 1.8 29 | # -dontobfuscate 30 | 31 | -keep public class * extends android.app.Activity 32 | -keep public class * extends android.app.Application 33 | -keep public class * extends android.app.Service 34 | -keep public class * extends android.content.BroadcastReceiver 35 | -keep public class * extends android.content.ContentProvider 36 | -keep public class * extends android.app.backup.BackupAgentHelper 37 | -keep public class * extends android.preference.Preference 38 | 39 | -keepclassmembernames class me.zhilong.tools.abortkiller.demo.MainActivity { 40 | private *; 41 | } -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | plugins { 2 | id 'com.android.application' 3 | id 'kotlin-android' 4 | } 5 | 6 | android { 7 | compileSdkVersion rootProject.ext.compileSdkVersion 8 | buildToolsVersion rootProject.ext.buildToolsVersion 9 | ndkVersion rootProject.ext.ndkVersion 10 | 11 | defaultConfig { 12 | applicationId "me.zhilong.tools.abortkiller.demo" 13 | minSdkVersion 16 14 | targetSdkVersion rootProject.ext.targetSdkVersion 15 | versionCode 1 16 | versionName rootProject.ext.versionName 17 | 18 | externalNativeBuild { 19 | cmake { 20 | abiFilters rootProject.ext.abiFilters.split(",") 21 | arguments "-DANDROID_STL=c++_shared" 22 | } 23 | } 24 | } 25 | 26 | buildTypes { 27 | debug { 28 | ndk { 29 | abiFilters "armeabi-v7a" 30 | } 31 | } 32 | release { 33 | minifyEnabled true 34 | proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' 35 | 36 | ndk { 37 | abiFilters "armeabi-v7a" 38 | } 39 | } 40 | } 41 | externalNativeBuild { 42 | cmake { 43 | path "src/main/cpp/CMakeLists.txt" 44 | version rootProject.ext.cmakeVersion 45 | } 46 | } 47 | compileOptions { 48 | sourceCompatibility JavaVersion.VERSION_1_8 49 | targetCompatibility JavaVersion.VERSION_1_8 50 | } 51 | kotlinOptions { 52 | jvmTarget = '1.8' 53 | } 54 | } 55 | 56 | dependencies { 57 | implementation project(path: ':patrons') 58 | 59 | implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version" 60 | implementation 'androidx.core:core-ktx:1.2.0' 61 | implementation 'androidx.appcompat:appcompat:1.2.0' 62 | implementation 'com.google.android.material:material:1.3.0' 63 | implementation 'androidx.constraintlayout:constraintlayout:2.0.4' 64 | } -------------------------------------------------------------------------------- /patrons/src/main/cpp/xhook/xhook.h: -------------------------------------------------------------------------------- 1 | // Copyright (c) 2018-present, iQIYI, Inc.
