An issue encountered during installation: A signed package that is re-installed via the ADB install will prompt for installation errors. Tip: Failure [install_failed_already_exists]

Why is eclipse itself able to keep covering the reload?

Because Eclipse automatic packaging is the signature of debug, and I play if the release signature will appear above the error. Workaround: adb install-r

ADB install-r here R is the abbreviation for reinstall. By the way, learn about the parameters of the ADB install.

ADB install-r (Reinstall) Reload

The ADB install-s (sdcard) is installed on the SD card instead of the internal storage

ADB uninstall-k (keep) retains user data.
