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
|
2018-03-06 02:27:31 +03:00
|
|
|
|
|
|
|
|
- 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
|
|
|
|
|
--------------------------------------------
|
2018-03-12 23:10:49 +03:00
|

|
2018-04-01 00:29:33 +03:00
|
|
|
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
|
2018-03-17 22:32:05 +03:00
|
|
|
|
|
|
|
|
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
|

|
|
|
|
2018-03-17 22:32:05 +03:00
|
|
|
Limitations:
|
|
|
|
|
- the screen size is currently fixed to 600x800 and is scaled up
|
|
|
|
|
- many many big and little functions are not yet implemented
