About apk update

Question

After installing the apk created by the xamarin forms archive on the device once, when I install the apk file with the changed version, the message "Could not install" is displayed.
How should I avoid it?

Answer 1

when you install the apk, connect the device to a PC where there is installed Android Studio, in LogCat you should see the error.
Otherwise download the logcat using adb command

adb logcat
This command will generate real-time output in command window. It can be stopped with CTRL+C

adb logcat –d > filename.txt
This command will extract the logcat information from the connected device and redirects the output to a file on the PC.
The option –d will take care that the output will stop when all output is flushed.

logcat -d -b main -b system -b events -v time > filename.txt
This command will extract the Android logcat information from all 3 given buffers (main, system and events), and will add the device timestamp for each line as well.
