Is your Android App installation or update failed?
Then you know this Android message: App Installation failed
Reason (in my opinion) probably a bad installation routine when updating some apps.
Here is what helped me:
- change the installation location of the app from the SD memory card to the internal memory
- reboot the device
- update the app
- change the installation location of the app back to the SD memory card (if you want)
Questions and Answers:
Q: Do I have to do this now every time?
A: I think not, because the problem is not an isolated case, soon a new update will solve the problem.
Q: Are all android apps affected?
A: So far, according to my experience affected only "Inbox" ® and "MX Player Pro" ®, so I do not think so.
