Support lowering minSDK upto 16 for Android

[sarbagyastha]

Used v1.1.0-alpha01 of androidx.media2.session, as it supports lowering minSDK upto 16.

Thanks for this PR. My personal inclination is that it is time to bump up the minSdkVersion, and I take Google's own decision to set the minSdkVersion for the "support" libraries to level 19 as a strong indication that it is time to move on. This level essentially gives a market share of 98.1%. Lowering this to level 16 adds an additional 1.7%, but it also means using an alpha version of the support library, and I'm not sure if I'm convinced yet whether that is a good idea.

However, I would be interested to hear your thoughts. Where do you draw the line on the minSdkVersion? Today, level 16 would give you a coverage of 99.8%. I have never before seen a default setting in Android Studio for minSdkVersion give a coverage this high, and I suspect they just forgot to update it for a while, whereas the support libraries have already moved on.

I would now like to present a counter argument to myself ;-)

I think this pull request couldn't hurt, and it would almost certainly make things easier for most people. It is very unlikely that the alpha status of this version of the support library will cause any issues given the part of the library that I am using doesn't do anything fancy.

My inclination may have changed to favour moving to this alpha version.

Merged, and that resolves the little debate I had with myself :-)

@ryanheise , just found out that this PR is causing issue with audio_service as the MediaControllerCompat in androidx:media is throwing RemoteException only for API>=21. But this seems to have been fixed since v1.2.0.

[ryanheise]

Thanks for catching that, I'm happy to accept another PR if you would like?

[ryanheise]

I've just had a chance to test this, and I see what you're referring to. I can change the audio_service code to catch Exception rather than RemoteException and that should prevent the error.

Although it would be good at some point to upgrade the media2 library.

[ryanheise]

audio_service 0.14.1 has been released which should fix this compatibility issue. Let me know how it goes for you.

[sarbagyastha]

Thanks for the update @ryanheise. It's working great now.
