Question

我在几个用户（运行android 7.0 / 7.1）崩溃，我无法重现。

崩溃发生在我试图获取已安装应用程序列表的模块中。我在真正的hw和各种模拟器上测试了应用程序没有问题。

我在下面显示了我的代码的简化版本。

崩溃的路线是：

ApplicationInfo ai = packageManager.getApplicationInfo(info.packageName, 0);

函数getInstalledAppList中的

。

ListApptest是一个从片段实例化的类：

ListApptest applications = new ListApp(getActivity());

我将packageManager初始化为activity.getPackageManager（），看起来getInstalledApplications（）运行正常（我可以添加对返回值的检查吗？）那么可能是PackageManager $ NameNotFoundException的原因？

getInstalledApplications如何返回未知的包名？

这是我的代码：

class ListApptest {
    private static final int flags = PackageManager.GET_META_DATA |
            PackageManager.GET_SHARED_LIBRARY_FILES |
            PackageManager.GET_UNINSTALLED_PACKAGES;

    private static Context context;
    private static Activity activity;

    private static PackageManager packageManager;

    ListApptest(Activity a, UsageStatsManager u, ListView l, ProgressBar p){
        activity = a;
        packageManager = activity.getPackageManager();
    }

    static class AppsGetInfo extends AsyncTask<Void, Void, Void> {
        private List<AppsItem> listAppsItem;

        @Override
        protected Void doInBackground(Void... arg0) {
            getInstalledApp();
            return null;
        }

        void getInstalledApp() {
            List<String> installedApps = getInstalledAppList();
        }

        private List<String> getInstalledAppList() {
            List<ApplicationInfo> infos = packageManager.getInstalledApplications(flags);
            List<String> installedApps = new ArrayList<>();
            for (ApplicationInfo info : infos) {
                installedApps.add(info.packageName);

                try {
                    // CRASH HERE
                    ApplicationInfo ai = packageManager.getApplicationInfo(info.packageName, 0);

                } catch (PackageManager.NameNotFoundException e) {
                    e.printStackTrace();
                }
            }

            return installedApps;
        }

     }
}

修改

我有一个友好的测试员（不是在同一个城市）发生了崩溃。我能够得到一些数据：

在infos = packageManager.getInstalledApplications：

之后

ApplicationInfo{69419b2 com.sec.factory}
ApplicationInfo{e8f5d03 com.samsung.knox.knoxtrustagent}
ApplicationInfo{4b3b480 com.android.htmlviewer},

坠机前：

com.sec.factory
com.samsung.knox.knoxtrustagent

所以它看起来像是在com.samsung.knox.knoxtrustagent崩溃？

可能是什么原因？你是如何解决这个问题的？
