Question

我使用DexClassloader从/ data / data / packagename /加载dex文件，就像：

private static synchronized Boolean injectAboveEqualApiLevel14(
            String dexPath, String defaultDexOptPath, String nativeLibPath, String dummyClassName) {
        BaseDexClassLoader pathClassLoader = (BaseDexClassLoader) DexInjector.class.getClassLoader();
        DexClassLoader dexClassLoader = new DexClassLoader(dexPath, defaultDexOptPath, nativeLibPath, pathClassLoader);
        try {
            dexClassLoader.loadClass(dummyClassName);
            Object dexElements = combineArray(
                    getDexElements(getPathList(pathClassLoader)),
                    getDexElements(getPathList(dexClassLoader)));
            Object pathList = getPathList(pathClassLoader);
            setField(pathList, pathList.getClass(), "dexElements", dexElements);
        } catch (Throwable e) {
            LogTool.i(TAG, "Throwable: " + e.toString() + "\n" + e.getMessage() + "\n");
            e.printStackTrace();
            return false;
        }
        return true;
    }

它在大多数机器和系统上运行完美....... 但今天，用户反馈说dex文件无法加载,,,这里的重要性错误日志：

12-03 15:19:12.725: E/dalvikvm(32068): waitpid failed: wanted 32099, got -1: No child processes
12-03 15:19:12.725: E/dalvikvm(32068): Unable to extract+optimize DEX from '/data/data/com.test.plugin/dex/classes1.dex', err: No child processes

手机信息：HTC 9060，Android 4.2.2，HTC Sense 5.0

这是一个奇怪的错误。这是完整的日志：

Android：DexClassLoader：无法从xx错误中提取+优化DEX：没有子进程
