Android Question How to test an apk on all versions of Android?

[vecino]

Hello, every now and then I get a call, or an email, from a customer who complains that something is not working.
After a lot of research I discover that the culprit is a change I don't know about in some version of Android that I haven't been able to test.

For example, the latest has been "GetSubscriberId" which now forces me to make changes in the program, notifying all customers to update and register again with a new identifier.

My problem in this case is that I don't have any device with a modern version of Android.
So my question is: how do you test your apk on all versions of Android?
I have three smartphones and three tablets, but the most modern one has Android 6.
Do I have to buy a device with every new Android version? I hope not
Any suggestions?
Thank you.

Also, with an android 9, the message is: App not installed.
:/

Try compiling with debug key.

With android version 9 the message is different:
App not installed.

I get that error message when compiling with the private key. Try the debug key.

 

[vecino]

What is "debug key"?

 

[Martin Larsen]

Signing your application before uploading to Google Play

The result of compiling your application is an APK file. This is a package file that contains the compiled source code and the assets files. The APK file must be signed before installation. Signing the file means that it is not possible to later modify it without the private key that was used to...

Oh, I don't use google play, I personally install on the clients' devices (not me, but a person in charge of doing it) and then the updates through a system I found from another person here, from these forums.

Hello, strangely enough, I have installed other programs of mine without any problem, but the one I am interested in now, impossible.
I don't know whether to continue here or open another thread for that topic.
How do you know why you can't install the program on genymotion?

I've uploaded a video capture for what it's worth.
Thank you.

I've already found the problem.
B4A Bridge!
If I uninstall it, then all the programs I install work.
What's the explanation?


EDIT (So as not to create a new "post"):
I've tried several versions and now it works well in all of them.
I use the drag and drop method.

Thank you all so much for your help.
Now I can try every time a new version of android comes out.

you don't need the bridge as geny uses adb aswell
