Generate Android library modules with resources

[borisf]

Generate Android library module with Android resources, while controlling programatically:

Strings, layouts, manifest, images

Several approaches:

1. Easy, Duplicating the basic elements

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme1" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

Can be easily cut of by the toolchain

2. More challenging, making sure that all the generated elements are get called, need to keep a model of everything in the project, loses simplicity

3. Pull sufficiently interesting modules from github. Requires some kind of analysis over github. Here is how to do it https://stackoverflow.com/questions/33066582/how-to-download-a-folder-from-github

Compromise between the first and the second ways, is to have one configurable number of activities == results in same number of auto generated layouts ==> same number of auto generated say text views inside a layout.

Thus we add one number to UI, that results in all project generation

Yeah, let's go for a mix. If we can generate activity with recycler view that has an adjustable number of types, then we can have as many different ViewHolders (aka layouts) as we want. To call all strings/images we will reference them from the layout. Generating images would be a bit trickier, although we can do both, jpeg generation and vector generation.

Generating images shouldn't be difficult, either we take one image and reuse it by different names or use BufferedImage API (https://docs.oracle.com/javase/tutorial/2d/images/drawonimage.html)
