android - 包 xyz 在设置中具有不匹配的 uid : 10044 on disk, 10045

Question

我找到了一个在虚拟机中安装 Android-x86 的简单指南 (guide)。
连接到 Eclipse 一切正常，但在 VM 上安装我的应用程序失败并出现以下错误:

06-21 22:40:26.390: INFO/PackageManager(2439): /data/app/xyz.apk changed; unpacking
06-21 22:40:26.390: ERROR/PackageManager(2439): Package xyz has mismatched uid: 10044 on disk, 10045 in settings
06-21 22:40:26.390: WARN/PackageManager(2439): Native ABI mismatch from package file
06-21 22:40:26.390: WARN/PackageManager(2439): Package couldn't be installed in /data/app/xyz-1.apk

我在 google 上搜索错误并找到了一个小的 Python 脚本来解决这个问题，但它不起作用 ( script )。执行脚本后，我得到了同样的错误。

我使用 Android-x86 2.2 generic，更多细节可以在这里找到:Release 2.2

有没有可能解决这个问题？

编辑:

我测试了所有 2.2 版本。一般只有 generic 和 sparta 工作，但是没有人接受我的 apk。
试过 adb install <packagefile>也是。

编辑2:

我已经尝试了@Vlad 推荐的工具。它在签署 apk 后部分工作。最后我用了 apkTools并将 apkEdit 的旧文件替换为 apktool 中的新文件。
但是使用 adb 的安装挂断并显示消息 waiting for device 或什么都没有。如果我相信 eclipse DDMS，每次我尝试安装 apk 时，与设备的连接都会丢失。
这是我尝试安装普通 apk 时的失败:Failure [INSTALL_FAILED_INVALID_APK]

错误 Package xyz has mismatched uid: 10044 on disk, 10045 in settings 由存在的文件夹 /data/data/xyz/ 引起。

在此消息中，文件夹存在并且拥有与现在安装的 (10045) 不同的所有者 (10044)。这是由以前的不干净安装引起的。

例如，之前的安装因一些错误而失败，并且不会删除创建的文件夹。

因为文件夹中可以是来自其他应用程序的数据，android 不允许使用它。 PackageManager 尝试以不同的方式修复它，但如果不能这样做 - 它会获取应用不同的目录并显示此消息。

更好的解决方案 - 安装应用程序并彻底删除它。之后再次安装。

另一种解决方案 - 以某些方式删除文件夹 /data/data/xyz/。可能您需要 root 权限。

来自 PackageManager 的代码(注释可能非常有帮助):

            // This is a normal package, need to make its data directory.
        dataPath = getDataPathForPackage(pkg.packageName, 0);

        boolean uidError = false;

        if (dataPath.exists()) {
            // XXX should really do this check for each user.
            mOutPermissions[1] = 0;
            FileUtils.getPermissions(dataPath.getPath(), mOutPermissions);

            // If we have mismatched owners for the data path, we have a problem.
            if (mOutPermissions[1] != pkg.applicationInfo.uid) {
                boolean recovered = false;
                if (mOutPermissions[1] == 0) {
                    // The directory somehow became owned by root.  Wow.
                    // This is probably because the system was stopped while
                    // installd was in the middle of messing with its libs
                    // directory.  Ask installd to fix that.
                    int ret = mInstaller.fixUid(pkgName, pkg.applicationInfo.uid,
                            pkg.applicationInfo.uid);

                    // current data so the application will still work.
                    int ret = mInstaller.remove(pkgName, 0);
