Multidex拆包异常java.lang.NoClassDef

Multidex的过程分两步，拆包和dex加载。

拆包

拆分为多个dex是在编译构建Dex过程中完成的，通过如下配置即可，同时在main-dex-rule文件中指定哪些类要放在主dex中。dex的命名规则是classes.dex、classes2.dex、classes3.dex等。

dexOptions {
    javaMaxHeapSize "1g"
    preDexLibraries = false
    additionalParameters = [//配置multidex参数
                            '--multi-dex',//多dex分包
                            '--set-max-idx-number=24000',//每个包内方法数上限
                            '--main-dex-list=' + projectDir + '/main-dex-rule', //打包到主classes.dex的文件列表
                            '--minimal-main-dex'
    ]
}

    -----main-dex-rule文件格式----
   com/pitaya/buckettool/BucketApplication.class
   android/support/multidex/MultiDexExtractor.class

加载

加载过程涉及多个目录文件、ClassLoader机制。

每个目录文件的作用

——/data/app/com.pitaya.buckettool-1.apk——applicationInfo.sourceDir sourceApk——系统用于存放APK原始安装文件

——/data/data/com.pitaya.buckettool——applicationInfo.dataDir——系统给每个应用创建的私有专用目录，存放SP、数据库等文件

——/data/data/com.pitaya.buckettool/code_cache/secondary-dexes——dexDir———Multidex工作过程中创建的目录，用于存放apk原始文件中的子dex，不包含主dex。

——/data/data/com.pitaya.buckettool/code_cache/secondary-dexes/com.pitaya.buckettool-1.apk.classes2.zip——extractedFile——Multidex工作过程中，
提取APK中的子dex，并生成包含子dex的压缩文件com.pitaya.buckettool-1.apk.classes2.zip，注意：每个子dex对应一个压缩文件。压缩文件内的dex名字被替换为了classes.dex，
为什么要这样做？因DexPathList.java底层是根据"classes.dex"字符串来匹配文件的，不符合的不处理。

——/data/data/com.pitaya.buckettool/code_cache/secondary-dexes/com.pitaya.buckettool-1.apk.classes2.dex——被dexOpt优化后生成的odex文件，可提高Dalvik执行效率，文件对比如下：
                -rw-r--r-- u0_a52   u0_a52     440576 2017-10-26 10:53 com.pitaya.buckettool-1.apk.classes2.dex
                -rw------- u0_a52   u0_a52     158841 2017-10-26 10:53 com.pitaya.buckettool-1.apk.classes2.zip

——/data/dalvik-cache/data@app@com.pitaya.buckettool-1.apk@classes.dex——系统用于存放主Dex

——/data/system/packages.xml——已安装应用的权限信息列表

遵循ClassLoader的双亲委派机制，并且判定是同一个Class的条件 = 相同的 ClassName + PackageName + ClassLoader。
PathClassLoader和DexClassLoader的区别在于，DexClassLoader可以指定odex路径。
关于ClassLoader的双亲委派、compile和provided两种依赖方式带来的异常ClassNotFoundException、ClassCastException、IllegalAccessError: Class ref in pre-verified class等异常，参见拓展阅读

摘抄：通过以上三种情况，主要是为了更加深刻的理解类加载器的知识，同时得出我们在开发插件时，尽量避免出现插件和宿主中都compile依赖，只保证compile一次，其他provided即可，此外在自定义DexClassLoader的parent时要特别注意，不能随意设置，一般设置成应用默认的classLoader，而非系统默认的classLoader。
被
dexopt过程，对加载的Class做预校验，包含该Class内所有的被引用的类是否存在，若不存在则对不存在的类做标记；该Class内所有引用类均在当前dex中，则该Class被标记为CLASS_ISPREVERIFIED。

BootClassLoader在哪里被实例化的呢？

Activity、ArrayList、ContextImpl、ActivityThread等系统的类都是由BootClassLoader加载的，BootClassLoader的实例化时机是在ZygoteInit的preload()方法中。BootClassLoader的parent是null，并且没有设置路径，可以理解为BootClassLoader是对底层loadclass能力的代理。
然后代码里和堆栈对不上，要看下老罗了。。。。

BootClassLoader.class本身又是由谁来加载的呢？奇怪

---------ZygoteInit.preload()-------
static void preload() {
    preloadClasses();
    preloadResources();
    preloadOpenGL();
}
---------ZygoteInit.preloadClasses()-------
Class.forName(line);
---------Class.forName()----------------------
if (loader == null) {
        loader = BootClassLoader.getInstance();
}
用于加载自定义Application的PathClassLoader在哪里实例化的呢？
AcitivityThread.java内部调用核心流程
-handleBindApplication(){Application app = data.info.makeApplication(data.restrictedBackupMode, null);}
    -LoadedApk.makeApplication()
        -java.lang.ClassLoader cl = getClassLoader();
            -createOrUpdateClassLoaderLocked()
                -mClassLoader = ApplicationLoaders.getDefault().getClassLoader(zip,
                        mApplicationInfo.targetSdkVersion, isBundledApp, librarySearchPath,
                        libraryPermittedPath, mBaseClassLoader);//设置outZipPaths.add(appDir);用于加载主Dex

------PathClassLoader实例化完毕，parent为BootClassLoader，并加载appDir路径下的主classes.dex文件，
自己定义的Application要放在主classes.dex中，在***自定义拆包的时候要注意***否则makeApplication()失败，
因为ClassNotFoundException-----

然后有NoClassDefFoundError

在BucketApplication的onCreate()方法中调用initBugly()，发生如下错误：

private void initBugly() {
    Beta.autoCheckUpgrade = false;
    CrashReport.UserStrategy strategy = new CrashReport.UserStrategy(getApplicationContext());
    Bugly.init(getApplicationContext(), "1111", BuildConfig.ENV_OFFLINE, strategy);
}

public class CrashReport {
    public CrashReport() {
    }

    public static class UserStrategy extends BuglyStrategy {
        public UserStrategy(Context context) {
        }
    }
}

 java.lang.NoClassDefFoundError: com.tencent.bugly.beta.Beta
  at com.pitaya.buckettool.BucketApplication.initBugly(BucketApplication.java:118)
  at com.pitaya.buckettool.BucketApplication.onCreate(BucketApplication.java:45)
  at android.app.Instrumentation.callApplicationOnCreate(Instrumentation.java:1007)
  at android.app.ActivityThread.handleBindApplication(ActivityThread.java:4344)

仔细看dalvikvm加载class的日志还有如下提示

W/dalvikvm: Unable to resolve superclass of Lcom/tencent/bugly/beta/Beta; (68)
W/dalvikvm: Link of class 'Lcom/tencent/bugly/beta/Beta;' failed
W/dalvikvm: VFY: unable to resolve static field 154 (autoCheckUpgrade) in Lcom/tencent/bugly/beta/Beta;

D/dalvikvm: DexOpt: unable to opt direct call 0x0165 at 0x12 in Lcom/pitaya/buckettool/BucketApplication;.initBugly


关键词
1、superclass  
2、unable to resolve static field
3、unable to resolve static method
4、unable to resolve new-instance

爽歪歪，后续的调试工作全是在为消灭这几句话做斗争。

解释下NoClassDefFoundError 和 ClassNotFoundException的区别：

为什么该类被提前标记为无效类呢？因为多Dex情况下，dexopt会扫描被该类A引用的所有的其他类是否存在，如果不存在，则其他类会被标记未无效类。
在加载Class到内存并初始化static、实例化Class时，发生NoClassDefFoundError异常。
如果初始化A的static块存在new B()并且类B的字节码还未被加载，则会产生ClassNotFoundException。
如果初始化A的static块存在new B()并且类B的字节码已被加载，但是new B()内构造函数抛出Exception导致类B实例化错误，同样导致类A字节码加载错误，后续有引用类A的地方也会发生ClassNotFoundException。看个腾讯Bugly的案例

 D/dalvikvm: DexOpt: unable to opt direct call 0x0071 at 0x1b in Lcom/pitaya/buckettool/BucketApplication;.onCreate

案例中BucketApplication 引用类有Beta.autoCheckUpgrade 、Bugly.init()、 CrashReport.UserStrategy.class。在main-dex-rule文件中新增如下配置，顺利看到了MainActivity页面。

com/tencent/bugly/a.class
com/tencent/bugly/beta/Beta.class

com/tencent/bugly/Bugly.class
com/tencent/bugly/BuglyStrategy.class
com/tencent/bugly/crashreport/CrashReport$UserStrategy.class

JVM类加载过程

类的加载分清楚如下两点：

摘要：一个类的生命周期包括加载（Loading）、验证（Verification）、准备(Preparation)、解析(Resolution)、初始化(Initialization)、使用(Using) 和 卸载(Unloading)七个阶段。
