How can you test your android project on all versions of android?

Question

Android

Hello, tell me how you can quickly test your apk on versions ranging from 2.2 to 5.
I understand that you need to specify the minimum api version for android 2.2 and it will work on lower versions of the OS.
But how to make sure that it will work correctly on all versions.
Do not offer an option with emulators - you can grow old.

Answer 1

Yes, Google's emulators are terrible. But there is an alternative - Genymotion - I highly recommend their emulations, but forget about Google ones altogether, although they also have some kind of optimization for Intel processors, such as HAXM emulations, which supposedly work faster.
As for services, there is also a testobject - here you can test it yourself, but for a fee, appthwack , well, if you haven’t been banned on Google, then you can still find them.

Answer 2

No way for free. Miracles don't happen. Look towards www.applause.com for similar services.

Answer 3

maybe because you don't have an input variable?
something like this is expected:
var input = $(this);

Answer 4

$('.video input').change(function(){
    var b=$(this).val();
    $('#i354').attr('src', b);
    
});
