Solved!..
There was another utility logger library initialized in the application class that prevented crashlytics from collecting log. https://github.com/hypertrack/hyperlog-android

Also the initialization & manifest part is not necessary unless you want to explicitly enable/disable crashlytics working.

The development team is using Tomcat 7 on Ubuntu server. I downloaded that Tomcat from the server and deployed locally and it works okay.

Now, I developed a spring-boot module, wrapped it into WAR file and wanted to deploy it in the same Tomcat. However, catalina.bat run fails to start my spring-boot application. The original application (called ROOT) is working fine.

Deploy to Tomcat 8 or later

Your error says the interface HttpSessionIdListener cannot be found.

Looking at the Javadoc for that interface tells us it was added in Servlet 3.1 specification.

Now look at the Which version? page on the Tomcat site. There we see that Tomcat 7 supports Servlet 3.0. For Servlet 3.1, you need Tomcat 8 or later.

Be aware that Tomcat 8.0.x has been superseded by Tomcat 8.5.x.

I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.

Xamarin.Android Camera Permissions with ZXing.Net.Mobile only works after app restart

Asked 2021-Oct-28 at 13:06

I am using ZXing.Net.Mobile in a Xamarin.Forms project. It works fine on iOS, but on Android, the first time I use the scanner, I get the camera permissions popup, and grant them.

There is no image from the camera immediately after the permissions. If I quit the app and re-launch, the camera works fine from that point forward. How can I get it to work right away? Even if I close my view, dispose and re-initialize it, it still doesn't work until the app restarts.
