ionic -v4: "App not installed:
I’m using ionic v4. I created my first app, signed it, and deployed on my phone (as a .apk file) and it worked normally.
Later, I created a new version, and generated another .apk file. When I opened the latter, it told me something like “are you sure you want to install an update for an existing app?” and when I agreed, it told me “App not installed”.
I’ve been searching a week for a solution, but didn’t find any.
Could someone help? Thanks in advance.
