Android12(API = 31) 在 loadPlugin 时出现Runtime::Abort, 猜测异常与 dex 创建有关 about shadow

[shifujun]

你贴的堆栈只能说明你用的不是这个项目的原始代码。而你又不愿意分享你修改后的代码。所以这没有开源项目的交流前提。

即便如此。你想知道在你拿了代码修改之后，上游项目改了什么。你可以简单的用git diff看出来多出来哪些提交，那些文件有差异。如果这些提交的提交日志不清晰，如果文件的改动看不懂，都可以直接引用提issue。要求改进也是合理的。直接提PR改进代码可读性也是欢迎的。

dex和oat都属于Android的私有api，shadow从原理上不考虑介入。

这里并没有对 Shadow 的 loadPlugin 相关流程以及代码做过修改，只是为了解决项目中其他第三方组件也使用了 shadow，导致包名冲突，将 com.tencent.shadow 修改为 com.tencent.estv.shadow;

如果说的是删除 oat 的逻辑，目前只是在 Shadow 提供的示例 FastPluginManager的 loadPlugin()方法中，增加了删除oat 文件的操作，为了避免Android P 内联优化导致的问题， 以下是相关代码；

    protected void loadPlugin(InstalledPlugin installedPlugin, String partKey, Boolean multiProcess) throws RemoteException, TimeoutException, FailedException {
        loadPluginLoaderAndRuntime(installedPlugin.UUID, partKey, multiProcess);
        Map map = mPluginLoader.getLoadedPlugin();
        if (!map.containsKey(partKey)) {
            delOatDir(installedPlugin);
            mPluginLoader.loadPlugin(partKey);
        }
    }

针对上游项目后续的改动，看到有针对 API 27 去掉 odex 的过程，这里会同步更新下相关改动尝试下。

但该问题是在sdk 升级到 targetSDKVersion = 30 时才出现，不确认是否是否该问题导致，后续如还有发现的话，会将 shadow 上游改动同步到项目中

获取到更详细的崩溃堆栈，目前看起来是崩溃在runtime 中的 vdex_file.cc中的GetNextDexFileData()方法，该方法在 Android12中引入, 在 Android12 版本的源码中，有CHECK_ALIGN(data,4)的检查

该 check 在 Android13 版本中去掉了
