Hi, java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

[HarborZeng]

I am using minSdkVersion 14 targetSdkVersion 25, and i encountered an error though followed your README.md.

mistake points to .show() and alertDialog = builder.show(); of InputDialog's show()

even I use that theme, the error still show up.

thank you.
