Android Question Problem with APK

[catyinwong]

I have re-installed the B4A in my new computer and somehow the projects (either released or debug through the B4A bridge) cannot be installed on my mobile. I can't figure out what I have set wrong. Can someone around give me a hint?

Paths Configuration:
javac.exe - C:\Program Files\Java\jdk1.8.0_171\bin\javac.exe
android jar - C:\Android\platforms\android-24\android.jar

Log:
LogCat connected to: B4A-Bridge: samsung SM-G5700
Installing file.
--------- beginning of main
Installing file.
Connected to B4A-Bridge (Wifi)
Installing file.
(And then the phone just stopped on the installation process saying "the app is not installed". Nothing else proceeded)

My phone has also enabled installation of apps not from Play Store.

You are probably using a different signing key. Uninstall the app from the device and then run it again.

The app cannot be installed in the mobile in the first place. The same happened even when I test with a blank new project with basically no code.

Press Ctrl + B and change the package name. Is it installed properly now?
