Added compatibility with Android API Level 10 and lower

[devilmac]

Hi DesarrolloAntonio,

this is not an issue but I want to tell you that I modified your library to be compatible with Android 10 and lower, because my project supports at least Android 10 and I want to add fragment transaction animations to it. I'm not able to create a pull request, but the changes done are quite easy and are the following:

• I added support library v4 for fragments
• I added library "NineOldAndroid" for support to animations
• I changed references for Activity with FragmentActivity of the support library in FragmentTransactionExtended class
• I changed references for all animation classes of Android with the same of NineOldAndroid library, always in FragmentTransactionExtended class

I have not yet tested these changes, but you could tell me if these changes are valid and reasonable.

Kind regards.

Federico

PS: sorry for my english ;)

Hi DesarrolloAntonio,

I hoped that these changes would have to work, but I'm encountering some problem with XML animation's "objectAnimator". I'm trying to create an animation working for Android Level 10 and lower to replace others with "objectAnimator".

Thanks for the contribution, I don't know what is the problem but maybe this library can help:
