A problem encountered during installation: for signed packages, re-passing adb install will prompt an installation error. Prompt: Failure [INSTALL_FAILED_ALREADY_EXISTS]
Why can eclipse itself keep overwriting and reinstalling?
Because eclipse's automatic packaging is a debug signature, and if it is a release signature, the above error will appear. Solution: adb install -r
adb install -r where r is short for reinstall. By the way, learn about the relevant parameters of adb install.
adb install -r (reinstall) reinstall
adb install -s (sdcard) installed on the SD card instead of internal storage
adb uninstall -k (keep) keeps user data.
---------------I am the dividing line, the following is my essay-------
I want to automatically install multiple apks, but the installation fails with INSTALL_FAILED_ALREADY_EXISTS error. Search the above article, and then use
adb install -r -s D:\news_share_apks\app-app2-release.apk command, perfect solution.
ps: As expected, -r and -s can be used together, -r solves the problem of reinstallation, and -s allows the application to be installed in the SD card. The ROM of my mobile phone is small, and I use an SD card, so I cover my face here, haha. Honor 7 in 2015.
In this way, I can use Python to automatically install the apk, saving time and effort.
