This adds a simple voice translator Android app that uses the JNI bindings to the PGF C runtime. Caveats: - Since the C runtime doesn't compile for Android right now, I've bundled an old copy, along with its Java bindings. That should be removed once the C runtime compiels for Android again. - Adding an automated build would be nice. - Replacing the grammar requires editing a Java file, that should really be more dynamic.

= Overview =
|
|
|
|
This directory contains a sample Android app tht uses
|
|
the Android speech recognition and TTS APIs along with
|
|
JNI bindings to the C PGF runtime to implement a simple
|
|
speech translation app.
|
|
|
|
|
|
= Requirements =
|
|
|
|
1. Android SDK: http://developer.android.com/sdk/
|
|
installed in $ANDROID_SDK_LOCATION
|
|
|
|
2. Android NDK: http://developer.android.com/tools/sdk/ndk/
|
|
installed in $ANDROID_NDK_LOCATION
|
|
|
|
= Building =
|
|
|
|
Set up Android project:
|
|
|
|
# Creates local.properties, not to be checked in
|
|
$ $ANDROID_SDK_LOCATION/tools/android update project -p .
|
|
|
|
Build libs/libjpgf.jar:
|
|
|
|
$ (cd ../../runtime/java && javac org/grammaticalframework/pgf/*.java && jar -cf libjpgf.jar org/grammaticalframework/pgf/*.class)
|
|
$ cp ../../runtime/java/libjpgf.jar libs
|
|
|
|
Build JNI code:
|
|
|
|
$ cd jni
|
|
$ $ANDROID_NDK_LOCATION/ndk-build
|
|
|
|
|
|
Build APK:
|
|
|
|
$ ant debug
|
|
|
|
|
|
Install on your device:
|
|
|
|
$ ant debug install
|
|
|
|
or:
|
|
|
|
$ adb install -r bin/MainActivity-debug.apk
|
|
|
|
|
|
= Changing the grammar =
|
|
|
|
1. Replace assets/ResourceDemo.pgf
|
|
|
|
2. Edit Translator.java to point to the new file and include its metadata
|
|
|
|
|
|
= Developing in Eclipse =
|
|
|
|
1. Install Android ADT
|
|
|
|
2. Eclipse > File > Import > Existing Projects into Workspace > Next
|
|
|
|
3. Select root directory...
|
|
|
|
4. Select GF/src/ui/android
|
|
|
|
5. Finish |
