Hi all,
My app not installing in release mode, Even I tried generating apk and installing but app is crashing every time.
I'm getting following error
Start debugging Android application failed
Start debugging Android application ...
am start -a "android.intent.action.MAIN" -c "android.intent.category.LAUNCHER" -n "com.test.demo/crc6409718adb1cab00c7.SplashActivity"
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.test.demo/crc6409718adb1cab00c7.SplashActivity }
Error type 3
Error: Activity class {com.test.demo/crc6409718adb1cab00c7.SplashActivity} does not exist.
The application could not be started. Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true).
Additionally, check Build->Configuration Manager to ensure this project is set to successfully
for this configuration.

Please set MainActivity as MainLauncher = true, then generate a apk, if you have same issue.
Hi @Leon Lu (Shanghai Wicresoft Co,.Ltd.)
Thanks for your response,
I'm getting this issue only for Andoid11 Devices only
I'm targeting to android11 also
Did you test it in android emulator? Is that worked?

I came across this error due to carelessness. I set up a pin code and fingerprint on the emulator. And I tried to deploy the application without unlocking the device and received this error

For me, this worked as a charm!
In Android Adb Command Prompt, type
adb -s <DEVICE> uninstall <PACKAGE>
should give you the word Success
adb -s <DEVICE> shell pm trim-caches 99999999
