Question

我正在恢复设备上安装的所有应用程序，我偶然发现了这个错误。

在doInBackground（）方法中，我使用此代码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);

发生崩溃的行是：

mResolveInfo = packageManager.queryIntentActivities(queryIntent, 0);

读取堆栈溢出我明白这可能是因为您安装了许多应用程序。现在的问题是，你怎么解决？有什么解决方案吗？如果是的话，哪一个？感谢。

我正在寻找相同的解决方案。有没有办法对已安装的应用程序进行部分列表？

我的应用程序中存在同样的问题。

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

如果用户拥有大量应用程序，我会在logcat中获得：

引起：java.lang.RuntimeException：包管理器已经死亡在android.app.ApplicationPackageManager.getInstalledPackages（ApplicationPackageManager.java:424）

引起：android.os.TransactionTooLargeException 在android.os.BinderProxy.transact（本机方法）在android.content.pm.IPackageManager $ Stub $ Proxy.getInstalledPackages（IPackageManager.java:2363）

更新！

我能找到一种方法。看到我在另一篇文章中给出的答案：

Package manager has died

android.os.TransactionTooLargeException检索已安装的应用程序
