+## Building FLTK with Android Studio 3
+
+There is no need to ever write a single line of Java.
+
+Download and install AndroidStudio on your developer machine. If you use
+AndroidStudio for the first time, use the IDE to download and build the
+"Native Plasm" sample app. In the process, all resources required to build
+FLTK will be installed. Once Native Plasm runs on your emulator or physical
+device, you are ready to install FLTK.
+
+Build FLTK for your native platform first using CMake. AndroidStudio will need a native
+version of the user interface design tool _Fluid_.
+
+The following example is for the _Xcode_ IDE on _macOS_. The same should work for 
+other IDEs and Makefiles on other platforms that run _AndroidStudio_.
+
+```bash
+git clone https://github.com/fltk/fltk.git fltk-1.4.git
+cd fltk-1.4.git
+mkdir build
+cd build
+mkdir Xcode
+cd Xcode
+cmake -G "Unix Makefiles" \
+  -D OPTION_USE_SYSTEM_LIBJPEG=Off \
+  -D OPTION_USE_SYSTEM_ZLIB=Off \
+  -D OPTION_USE_SYSTEM_LIBPNG=Off \
+  -D OPTION_CREATE_ANDROID_STUDIO_IDE=On \
+  ../..
+```
+Note the last option, `-D OPTION_CREATE_ANDROID_STUDIO_IDE=On`. This option will 
+create the file needed to create an FLTK demo project in 
+`fltk-1.4.git/build/Xcode/AndroidStudio`.
+
+- open the `build/Xcode/AndroidStudio/` directory as a project in AndroidStudio3
+
+- click "run"; the project should compile and run out of the box
+
+
+## Extensions and limitation of FLTK on Android
+
+Android support for FLTK is in an early stage. As of January 2019, most
+rendering works, fonts work, bitmaps and pixmaps work, clipping works, window
+layering works, and mouse clicks and keyboard events are handled
+
+When loading fonts:
+ - font names starting with a $ will have the system font path inserted
+ - font names starting with an @ will be loaded via the Asset Manager
+ - all other names will be used verbatim
+
+Limitations:
+ - the screen size is currently fixed to 600x800 and is scaled up
+ - many many big and little functions are not yet implemented
+
+

+Mar 29 2018 - matt: many graphics functions have been implemented, keyboard

-BUILDING FLTK SAMPLE WITH ANDROID STUDIO 3
-------------------------------------------
-
-There is no need to ever write a single line of Java.
-
-Download and install AndroidStudio on your developer machine. If you use
-AndroidStudio for the first time, use the IDE to download and build the
-"Native Plasm" sample app. In the process, all resources required to build
-FLTK will be installed. Once Native Plasm runs on your emulator or physical
-device, you are ready to install FLTK.
-
-- if your host machine runs MSWindows, rename the file
-  "ide/AndroidStudio3/gradlew.rename_to_bat" to "gradlew.bat" first
-
-- open the "ide/AndroidStudio3/" directory as a project in AndroidStudio
-
-- click "run"; the project should compile and run out of the box
-
-
-Building Apps on an Android device with C4Droid
------------------------------------------------
-
-WORK IN PROGRESS:
-C4Droid is a minimal IDE that comes with gcc/g++ and runs directly on your
-Android device. C4Droid supports Native Activities, SDL, SDL2, and even Qt.
-FLTK uses the Native Activity mechanism, so why not write FLTK apps right
-on your phone?
-
- - compile and test the Android test app in ide/HelloAndroid
- - create /sdcard/include/ and /sdcard/lib/ on your Android device
- - copy (fltk)/FL/ and its content into /sdcard/include/
- - copy (fltk)/ide/AndroidStudio3/FL/abi-version.h to /sdcard/include/FL/
- - copy (fltk)/ide/AndroidStudio3/./app/.externalNativeBuild/cmake/debug/arm64-v8a/fltk/lib/libfltk.a
-   to /sdcard/lib/
- - ... change Native Activity settings in c4Droid preferences
- - ... remove native glue
- - ... add include and library path, add library
- - ... add support for (which?) STL library
-
-
-Extensions and limitation of FLTK on Android
---------------------------------------------
-
-Android support for FLTK is in an early stage. As of March 2018, most
-rendering works, fonts work, bitmaps and pixmaps work, clipping works, window
-layering works, and mouse clicks and keyboard events are handled
-
-When loading fonts:
- - font names starting with a $ will have the system font path inserted
- - font names starting with an @ will be loaded via the Asset Manager
- - all other names will be used verbatim
-
-Limitations:
- - the screen size is currently fixed to 600x800 and is scaled up
- - many many big and little functions are not yet implemented
-

-# Hello Android
-
-Hello Android is an FLTK sample app that derives from the Android Studio sample
-project Native Plasma. This sample uses Android Studio 3 and CMake.
-
-

-1. Launch Android Studio.
-1. Open the `IDE` directory inside the FLTK directory.
-1. Open the Android Studio project by loading the `AndroidStudio3` directory.
-1. Click *Run/Run 'app'*.
-
-
-## Support
-
-If you've found an error in these samples, please [file an issue](http://www.fltk.org/str.php). Patches are encouraged, and may be submitted via the same FLTK Bug & Feature system.
-
-Please visit the FLTK [Forum](http://www.fltk.org/newsgroups.php) for additional help.
-

-## Android Shell
-
-List of short little helpers:
-
-```bash
-am start -n org.fltk.android_hello/android.app.NativeActivity
-am force-stop org.fltk.android_hello
