This file set contains new files, and changes to existing files, that will enable PhysicsEffects
|
|
and several sample apps to be built and run on Android devices. The Android projects are
|
|
a mix of Java and C++ code. The code has been tested using Android NDK r5c. Build files
|
|
are provided for the NDK and ANT. Here are some instructions on how
|
|
to update the baseline PhysicsEffects branch of Bullet to support Android using the provided
|
|
files:
|
|
|
|
1. For Windows platforms, download and install Cygwin (if it is not already installed)
|
|
2. Download and install the Android SDK.
|
|
3. Download and install the Android NDK. (The files provided have been tested with NDK r5c.)
|
|
|
|
4. Set up these new environment variables:
|
|
|
|
BULLET_PFX_ROOT_CYGWIN = path to your PhysicsEffects folder, for example:
|
|
BULLET_PFX_ROOT_CYGWIN=/cygdrive/d/tools/Bullet/branches/PhysicsEffects
|
|
|
|
CYGWIN_ROOT = path to where Cygwin is installed (Windows-style path)
|
|
ANDROID_NDK_ROOT = path to where the Android NDK is installed
|
|
|
|
5. Open a Cygwin console. Browse to the PhysicsEffects/project/Android
|
|
folder. Then, for each package, starting with PfxLibrary, go into the
|
|
package folder and run the ndk-build command. For example:
|
|
|
|
/PhysicsEffects/project/Android/PfxLibrary> /cygwin/d/tools/android-ndk-r5c/ndk-build
|
|
|
|
Build every package using ndk-build.
|
|
|
|
(It is possible to configure Eclipse to use ndk-build, but that is somewhat
|
|
tedious to do.)
|
|
|
|
6. For each application package (PfxApp*) after running ndk-build use
|
|
ant compile
|
|
ant debug
|
|
|
|
If your Android device is connected and setup, you can also run the app using
|
|
ant install
|
|
|
|
7. If you run the app, you can interact with the touch interface:
|
|
|
|
- Tap the screen to change scenes
|
|
- Pinch the screen to zoom in/out
|
|
- Drag the screen to rotate the camera
