Add Android Support

[Swordsman-Inaction]

Hey!

We'll have Android Support now! You guys can check the README about this.

This feature is not perfect, since there is no keyboardWillShow on Android, we cannot be notified before the keyboard is showed. So sometimes we could get wrong position of focused TextInput because it's already in the process of showing keyboard which makes keyboardSpace not accurate occasionally.

Feel free to review the code and test on your app!

Fix #2

@chirag04 @Palisand @Jose4gg @tizzyapunkt Would you like to test this feature? 😀

[Palisand]

@Swordsman-Inaction Unfortunately, I am unable to test this. Since I am using Expo, windowSoftInputMode is set to adjustResize and I cannot change it to adjustPan unless I detach.

[Swordsman-Inaction]

@Palisand OK... I don't use adjustResize because this option will change the window size which makes positioning more difficult. Also this option doesn't have scroll animation.

[Palisand]

@Swordsman-Inaction With these changes, space gets added below the view holding the input, so it works just fine if I scroll manually. By the way, are there any plans for making the view scroll to the text input cursor (for multiline inputs) rather than the bottom of the input? I've tried to accomplish this myself, but found that RN doesn't expose the cursor's location.

I used this as a drop in replacement for the APSL version for my project and it worked perfect. Thanks Swordsman-Inaction! When will this request get merged?

@Palisand The first issue, space gets added below the view, is it been introduced in this PR? Is it related to #142?
About the second one, scroll to the text input cursor, as you mentioned RN doesn't expose the cursor's location, it might be impossible to do it. I haven't got time to do the research, I'll do it later, maybe try to work on the native level.

[Palisand]

@Swordsman-Inaction I've only compared APSL's master version and your forked repo's android-support branch and with the latter, space does get added below the view when I focus on the input. I wasn't treating it as an issue as I thought this was intentional (and it's a welcome change).

From what I've learned, the second one appears possible only on the native level.

[Swordsman-Inaction]

@Palisand I see, you are saying extraHeight and extraScrollHeight works on Android now, right?

[Palisand]

@Swordsman-Inaction I never included nor tested those props, only enableOnAndroid. What I'm saying is that before your changes, I was unable to scroll (manually) to an input on Android when the keyboard was shown. Since I can now, I am assuming there is some space being added below the view holding the input.

[Swordsman-Inaction]

@Palisand Yes, that's right. 😀

[alvaromb]

Seems good to merge! Have you tested it under Android?

[alvaromb]

@Swordsman-Inaction ping me when all the PRs are merged and I'll perform a release. Thanks for your work!

[nicotroia]

I've upgraded to react-native 0.46.+, changed my AndroidManifest file, and set enableOnAndroid to true, and still cannot get any extra padding via extraHeight or extraScrollHeight. Neither work for me

[alliecurry]

@nicotroia I don't believe there was a new release of this library, yet even though this is merged in.

[alvaromb]

I'm waiting for @Swordsman-Inaction confirmation to release 0.3.0.

[apaul314]

@Swordsman-Inaction any updates?

[Swordsman-Inaction]

@hose314 Should be released soon, already confirmed with @alvaromb before. 😄

[alvaromb]

I can confirm it will be released tomorrow morning CEST.

Thanks!
