problems encountered
-
Running in Debug mode, it prompts that
the adb.exe process is blocked by anti-virus software, and the firewall software and anti-virus software need to be uninstalled -
After loading the generated project, it prompts
to reinstall Android Studio and use the same version as the original project -
The error pop-up window prompting Application installation failed
is as shown in the figure:
Installation failed with message Failed to finalize session: INSTALL_FAILED_TEST_ONLY: installPackageLI.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
1. Try again after Clean Project, if it still doesn't work, uninstall the app on the emulator.
2 Solutions:
1. Open the menu File——Settings——Build, Execution, Deployment——Instant Run
2. Uncheck Enable Instant Run to hot swap code/resource changes on deploy (default enabled)
3. Click Apply—— OK, re-run the program, and you're done.
Will add to other problems in the future.
