检索已安装应用程序时发生android.os.TransactionTooLargeException异常

8

我正在恢复设备上安装的所有应用程序，但遇到了此错误。

在doInBackground()方法中，我使用以下代码来检索已安装的应用程序。

    PackageManager packageManager = getPackageManager();
    List<ResolveInfo> mResolveInfo;
    Intent queryIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER);
    mResolveInfo = packageManager.queryIntentActivities(queryIntent, 0);
    for (ResolveInfo ri : resolveInfos) {
        Class class = new Class();
        class.icon = ri.loadIcon(packageManager);
        class.label = ri.loadLabel(packageManager);
        class.packagename = ri.activityInfo.packageName;
        class.packageclass = ri.activityInfo.name;
        class.componentName = new ComponentName(class.packagename, class.packageclass);
        Intent i = new Intent(Intent.ACTION_MAIN);
        i.addCategory(Intent.CATEGORY_LAUNCHER);
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
        i.setComponent(ai.componentName);
        class.intent = i;
        myArrayList.add(class);

发生崩溃的代码行是这样的：

mResolveInfo = packageManager.queryIntentActivities(queryIntent, 0);

从Stack Overflow的阅读中，我了解到这可能是由于您安装了许多应用程序所导致的。现在的问题是，你该如何解决？有没有解决方案？如果有，那个是什么？谢谢。

我在谷歌的预发布报告云测试实验室中，在 Nexus 5 上调用 PackageManager.getInstalledPackages(PackageManager.GET_ACTIVITIES) 时遇到了完全相同的错误。 - Sam

我正在寻找相同的解决方案。有没有办法列出已安装应用程序的部分列表？

我的应用程序也遇到了同样的问题。

List<PackageInfo> packs = pm.getInstalledPackages(0);

如果用户安装了大量应用程序，我在logcat中会看到以下内容：

Caused by: java.lang.RuntimeException: Package manager has died at android.app.ApplicationPackageManager.getInstalledPackages(ApplicationPackageManager.java:424)

Caused by: android.os.TransactionTooLargeException at android.os.BinderProxy.transact(Native Method) at android.content.pm.IPackageManager$Stub$Proxy.getInstalledPackages(IPackageManager.java:2363)

更新！

我找到了一种方法。请参见我在另一篇帖子中提供的答案：
