通过Eclipse安装时,Android App崩溃了

Question

每次重新安装我的日蚀时,我都会收到以下异常.每次我重新安装当前位于前台的应用程序时都会发生这种情况.

我希望这个错误只发生在开发期间,因为我通过Eclipse卸载正在运行的应用程序.

有没有人在用户手机上看到此错误？

当我转向使用ICS的Galaxy Nexus时,这开始发生在我身上.

在上面的日志中,我找不到任何与我的申请相关的东西.但它仍在崩溃.

谁能告诉我这是什么原因？这是Galaxy Nexus冰淇淋三明治中的一个错误吗？

该方法的第 346 行有一个空指针initializeJavaContextClassLoader。

这是来自GrepCode/com.google.android/android/2.3_r1/ android.app.LoadedApk的方法（从 开始line 326）

private void initializeJavaContextClassLoader() {
    IPackageManager pm = ActivityThread.getPackageManager();
    android.content.pm.PackageInfo pi;
    try {
        pi = pm.getPackageInfo(mPackageName, 0);
    } catch (RemoteException e) {
        throw new AssertionError(e);
    }
    /*
     * Two possible indications that this package could be
     * sharing its virtual machine with other packages:
     *
     * 1.) the sharedUserId attribute is set in the manifest,
     *     indicating a request to share a VM with other
     *     packages with the same sharedUserId.
     *
     * 2.) the application element of the manifest has an
     *     attribute specifying a non-default process name,
     *     indicating the desire to run in another packages VM.
     */
    boolean sharedUserIdSet = (pi.sharedUserId != null);
    boolean processNameNotDefault =
            (pi.applicationInfo != null &&
            !mPackageName.equals(pi.applicationInfo.processName));
    boolean sharable = (sharedUserIdSet || processNameNotDefault);
    ClassLoader contextClassLoader =
            (sharable)
            ? new WarningContextClassLoader()
    : mClassLoader;
            Thread.currentThread().setContextClassLoader(contextClassLoader);
}

看起来您可能正在尝试与另一个包共享虚拟机。
