Project scenario: Android mobile phone installs apk file, prompts that the application is not installed
When installing the apk file generated through Andorid studio packaging on an Andorid phone, it prompts that the application is not installed.
When installing the apk file on the phone, it prompts "The application is not installed"
Cause Analysis:
It may be that the version of the Andorid system on the phone is too low.
You can go to the settings on the phone - about the phone to check your Android version. My
version is 6.0, so when I install the program, it cannot be installed normally.
solution:
When using Andorid studio to package and sign, we usually check V2. However, when the Android system version of the phone is too low, the error shown above will appear and the application is not installed.
Check V1, the packaged apk file can be installed normally on Android 7.0 and lower versions. Check
V2, the packaged apk file can be installed normally on Android 7.0+ mobile phones. At
the same time, check V1 and V2. The packaged apk file can be installed normally on Android 7.0+ or versions below 7.0
