多个dex合并遇到的问题

合并使用到的技术

/**** @param mainclassLoader 合并到这里* @param pluginClassloader 被合并的dex*/public static void mergeDex(ClassLoader mainclassLoader,ClassLoader pluginClassloader){/*    String cachePath = context.getCacheDir().getAbsolutePath();String apkPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/plugin.apk";DexClassLoader pluginClassloader = new DexClassLoader(apkPath, cachePath, cachePath, context.getClassLoader());*///     第一步   找到    插件的Elements数组  dexPathlist  ----？dexElementtry {
//            Class myDexClazzLoader=pluginClassloader.getClass();Class myDexClazzLoader=Class.forName("dalvik.system.BaseDexClassLoader");Field myPathListFiled=myDexClazzLoader.getDeclaredField("pathList");myPathListFiled.setAccessible(true);Object myPathListObject =myPathListFiled.get(pluginClassloader);Class  myPathClazz=myPathListObject.getClass();Field  myElementsField = myPathClazz.getDeclaredField("dexElements");myElementsField.setAccessible(true);
//          自己插件的  dexElements[]Object myElements=myElementsField.get(myPathListObject);//     第二步   找到    main的Elements数组    dexElements
//            ClassLoader pathClassLoader=mainclassLoader;Class baseDexClazzLoader =Class.forName("dalvik.system.BaseDexClassLoader");Field pathListFiled = baseDexClazzLoader.getDeclaredField("pathList");pathListFiled.setAccessible(true);Object pathListObject = pathListFiled.get(mainclassLoader);Class systemPathClazz = pathListObject.getClass();Field systemElementsField = systemPathClazz.getDeclaredField("dexElements");systemElementsField.setAccessible(true);//系统的  dexElements[]Object systemElements = systemElementsField.get(pathListObject);//     第三步  上面的dexElements  数组  合并成新的  dexElements     然后通过反射重新注入系统的Field (dexElements )变量中//       新的     Element[] 对象
//            dalvik.system.Elementint systemLength = Array.getLength(systemElements);int myLength = Array.getLength(myElements);
//            找到 Element  的Class类型   数组    每一个成员的类型Class<?> sigleElementClazz = systemElements.getClass().getComponentType();int newSysteLength = myLength + systemLength;Object newElementsArray=Array.newInstance(sigleElementClazz, newSysteLength);
//融合for (int i = 0; i < newSysteLength; i++) {
//                先融合 插件的Elementsif (i < myLength) {Array.set(newElementsArray, i, Array.get(myElements, i));}else {Object value = Array.get(systemElements, i - myLength);Array.set(newElementsArray,i, value);}}Field  elementsField=pathListObject.getClass().getDeclaredField("dexElements");;elementsField.setAccessible(true);
//            将新生成的EleMents数组对象重新放到系统中去elementsField.set( pathListObject,newElementsArray);} catch (Exception e) {e.printStackTrace();}}

这个问题是因为我的情迁红包插件apk，它给每一个apk都加入了友盟，里面使用到了友盟，结果也被加载进来了。那么这样的合并代码显然是有问题的，那么为什么xposed融合就没有问题呢？我直接不跟主classloader融合了。

问题2 LinkageError:No superclass defined for class

No superclass defined for class java.lang.Object(declartion of ''java.lang.Object") appears in /data/user/0/xxxxx/apk_robot_out/class.dex

忘记注意classloader为空了。

DexClassLoader currentClassloader = new DexClassLoader(
file.getAbsolutePath(), 
dataDir.getAbsolutePath(), 
packageInfo.applicationInfo.nativeLibraryDir, 
MainActivity.this.getClassLoader());
