android - startActivity intent is crashing on app upgrade in android 10 & above

问题描述

Below is my code bit.

Intent installIntent = new Intent(Intent.ACTION_VIEW);
installIntent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/Download/<filename>.apk")),"application/vnd.android.package-archive");
installIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
installIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(installIntent);

Logs attached below.

解决方案

您没有附加任何日志，但分析了您的代码，我认为此崩溃可能与 Android 10（文件访问）中的隐私更改有关。您可以在此处阅读有关此内容的更多信息：https ://developer.android.com/about/versions/10/privacy/changes#scoped-storage
