Android Question Can't install on other device

hey, i got a strange problem. (to me strange, probably the solution is totally simple)

I can compile my app normally via USB connection and install it on my phone.
However, if I connect another mobile/tablet, this will not work. Both have the developer option enabled and USB debugging.

I get the following error message when I try to compile the app:


In my manifest I use this line:

<uses-sdk android:minSdkVersion="28" android:targetSdkVersion="28"/>
Click to expand...

Any idea what the problem is? I would be grateful for any help.

Thanks in advance!

Do the 'other' devices have a new enough version of android. You have set the Min to 28. So devices need at least version 28. If you don't NEED ver 28 for the app to operate then target the desired, but set min lower.

p.s. sdk version 28 is Android Pie. So anything running an SDK level below this will reject the install.

Have you pressed Ctrl-P (clean project) before compile with the new phone?
