I have published my App on PlayStore. And Installed in my devices from PlayStore as well.
There were some problems by me in TinyDB so I solved them in Kodular. And now it is working fine in Test mode of Kodular. I exported APK and tried to installed on my device. And I got error message "App not installed ". So I tried to install on other devices and same problem,
I uninstalled app and re-install it in my device and it worked. But all my TinyDB tags were deleted because of uninstall.
So how can I update APK from devicewithout uninstall App that is downloaded from PlayStore.
Use Google drive(or any cloud storage) instead of WhatsApp for sharing spk
This always happens to me, when I share aok through WhatsApp
Check your app Minimum API level.
During installing updated apk always uninstall previous one and installl updated.
Check That This App Has Been Installed From Playstore And Installed Again Through WhatsApp Method . If You Have The Same App In The Device Through Playstore Uninstall It And Reinstall Through WhatsApp Method
Actually Your App Signature should be same but if you upload app to play store then Google automatic change Signature so You can’t update app … But I think if you increase version code then you’ll be able to update … Try it (I’m not sure about it)
I tried Google Drive and Dropbox as well. It didn’t worked. Also tried loacl storage but it didn’t worked.
If I uninstall it, My TinyDB tags get removed and I don’t know if problem is solved or not.
On Play Store it’s version 2. And the new APK I am trying is version 3. No it didn’t worked as well.
Can You Just Show Me Your Apk I will Try In Some Devices And By My Phone And Emulator
Thank you for you help. I found problem. It is certificate problem. SO apps that is downloaded from PlayStore can not be update by APK from Device. You have to uninstall it and Install from device
