包xyz的uid不匹配:磁盘上的10044,设置中的10045

Question

我找到了一个在VM中安装Android-x86的简单指南(指南).
连接到Eclipse并且一切正常,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

我在谷歌搜索错误,发现一个小的Python脚本来解决问题,但它不起作用(脚本).执行脚本后,我得到了同样的错误.

我使用Android-x86 2.2泛型,更多细节可以在这里找到:2.2版

有没有可能解决这个问题？

编辑:

我测试了所有2.2版本.只有泛型和sparta一般工作,但没有人接受我的apk.
也试过adb install <packagefile>.

EDIT2:

我试过@Vlad的推荐工具.它在签署apk后部分工作.最后我使用了apkTools并用apktool中的new替换了apkEdit的旧文件.
但是adb的安装会挂起等待设备的消息或什么都没有.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]

Package xyz has mismatched uid: 10044 on disk, 10045 in settings由存在文​​件夹引起的错误/data/data/xyz/。

此消息文件夹中存在，并且具有与现在安装的 (10045) 不同的所有者 (10044)。这是由于之前安装不干净造成的。

例如，之前的安装因一些错误而失败，并且不要删除创建的文件夹。

因为文件夹中可能包含来自其他应用程序的数据，所以 Android 不允许使用它。PackageManager尝试以不同的方式修复它，但如果不能做到这一点 - 它会获取应用程序不同的目录并显示此消息。

更好的解决方案 - 安装应用程序并干净删除它。之后再次安装。

另一个解决方案 -/data/data/xyz/以某种方式删除文件夹。可能你需要 root 才能做到这一点。

代码来自PackageManager（评论可能非常有帮助）：

            // 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
