application继承的是MultiDexApplication，内部使用了静态变量okhttp 声明： public static final OkHttpClient client = new OkHttpClient();
然后就报错了

如题

编译出的apk包在Android 6.0上无法安装，直接通过Android studio 运行的程序可以运行，且运行正常。5.0上也能正常。只提示应用无法安装。

请问这个apk是在里面起什么作用

distributionUrl=https://services.gradle.org/distributions/gradle-2.4-all.zip
将版本换成 2.8会有问题吗

如题

classpath 'com.android.tools.build:gradle:1.5.0'

nvwa ? nuwa ?

并没有生成patch.jar
有的时候会生成一个a.class 反编译之后 发现就是修复bug 后的类 但并没有生成jar
mac win都是一样

使用1.5.0版本的com.android.tools.build:gradle时，调用apply plugin: "cn.jiajixin.nuwa"会提示
Error:Cannot get property 'taskDependencies' on null object
回滚到1.3.1后没有问题。

根据Qzone那篇原始文章里面描述，需要对直接引用Hello的类(Sample中的MainActivity)进行消除CLASS_ISPREVERIFIED的操作，但在生成的patch.jar去只看到Hello本身的Hack字节码插入，这其中是什么原理？

这个项目可以用作插件式开发吗？

reference MultiDex

如果做的是一个sdk的话
apply plugin: 'com.android.library'，再声明apply plugin: "cn.jiajixin.nuwa"
就会报如下错
Could not find property 'applicationVariants' on com.android.build.gradle.LibraryExtension_Decorated@6de81701.

Andfix已经对安全和版本管理做的不错了。dodola有兴趣一起搞啊

使用sdk 报这个错误是什么原因

Error:Execution failed for task ':app:nuwaClassBeforeDexBaidushoujizhushouDebug'.

在ART会编译成native代码。
但是如果只发布部分代码的话，编译时是没办法进行内存地址定位的。
ART模式下也会分为解释执行与ART native模式执行，如果只是走解释执行，就还是按照原来dalvik的模式走的，用的符号引用，没问题，但一旦ART模式，比如你用handler调用你的补丁文件，内存地址就飞了，必定报错。

解决方式：从理论上来说，只发布部分class是不行的，整个dex必须都要作为patch...

可能作者的这套还没经过多少实际应用吧，其实还有很多的坑在里面，这套机制的局限性还有很多。
比如Application,provider等里面千万不能引用其他的class，android:process的处理等

另外windows下的cygwin中使用貌似也不行

生成patch.jar的时候,已显示BUILD SUCCESSFUL,但实际没生成patch.jar.

@jasonross 我在阿里云移动测试平台上面对Nuwa做了下兼容性测试，发现有个特定的机型补丁打了没起效果：http://mqc.aliyun.com。 机器型号是 三星 SM-N9108V 4.4.4 1440x2560 armeabi-v7a。下了logcat的输出文件看了一下，发现hack.dex和patch.dex都已经被成功解压放进了工程目录。有点怀疑dex载入顺序在某个节点被系统给重置回去了。

打正式版的包有了mapping.txt文件，补丁是按照demo那样打的。但是再次进应用的时候出现了这样的问题。

E/nuwa: inject /data/data/com.android.benlailife.activity/files/nuwa/hack.apk failed
E/dalvikvm: Could not find class 'cn.jiajixin.nuwa.Hack'
这个是因为什么原因引起的

集成nuwa后build出错，环境和nuwaSample配置一样。
使用命令：gradlew clean --stacktrace --debug

我将gradle版本修改为1.5后：classpath 'com.android.tools.build:gradle:1.5.0'
项目会报这个错 Error:Cannot get property 'taskDependencies' on null object
导致项目初始化失败！

按照readme中的步骤集成Nuwa后，运行报异常：
Error:Execution failed for task':app:nuwaClassBeforeDexDebug'.> 1

用到修改的类时一直报 java.lang.IllegalAccessError: Class ref in pre-verified class resolved to unexpected implementation 这个错误

为什么我用dx --dex --output=patch.apk patch生成的apk文件中没有dex文件呢。
不会生成classes.dex

打补丁的时候还需要准备一个excludeClass的列表比较麻烦，感觉可以在类里面增加一个标志，执行的时候发现class里有这个标志就跳过这个

classpath 'cn.jiajixin.nuwa:gradle:1.2.1' 这个依赖是怎么实现的，有没有代码看看呀，jcenter上搜索不出来额。

启动后找不到GuideActivity_了，项目中使用了androidannotations开源框架

用你的demo成功了。
然后放到自己项目里面试了下，发现没生成patch文件，只生成了一个patch目录。命令行运行生成补丁的命令是成功的，但是就是没有文件出来。求解

我现在有个场景，就是在debug编译类型下，不用nuwagradle处理，在release模式下才启用，但是build.gradle文件只有一份，若集成了apply plugin: "cn.jiajixin.nuwa"，那无论哪个模式下都会调用nuwagradle的处理。

在build.gradle

设置 multiDexEnabled false
Nuwa编译不通过报错app:nuwaClassBeforeDexDebug FAILED

设置multiDexEnabled true
Nuwa编译通过，但是项目运行报错

这个错误怎么解？是不是Nuwa初始化的代码需要做延时处理？还是其他什么办法？
求答案！Thanks

说说我在实战中遇到的问题

首先是混淆，打修复包时利用正式包的mapping，修复bug，修改了原先的类，改变的类会改变，但有些类没有改变也会因为混淆的关系产生变化（混淆会剔除一些无用的方法，打修复包时那些无用的方法可能会加上），这就造成了有些类没有修改，但也会出现在修复包中。

再次是平台兼容问题，以前一直以为可以完全兼容ART环境。如果仅仅是修复一个小bug，比如改变了一行输出。那么在Android4.0和5.0上都可以修复，但如果修复一个稍微复杂的bug，可能牵连到的类就比较多了，在4.0环境上可以修复，在5.0环境上直接引起了其它的问题，导致崩溃。

按照说明运行demo，但执行这句命令报错：
./gradlew clean nuwaQihooDebugPatch -P NuwaDir=/Users/zhangsan/Downloads/download_demo/nuwa
报的异常：
Caused by: org.gradle.api.InvalidUserDataException: $ANDROID_HOME is not defined

请问这个怎么解决？
