			   LINPHONE for ANDROID
			****************************

To build liblinphone for Android, you must:
0) download the Android sdk with platform-tools and tools updated to latest revision (at least API 16 is needed), then add both 'tools' and 'platform-tools' folders in your path.
1) download the Android ndk (>=r9d) from google and add it to your path (no symlink !!!).
2) install yasm, nasm, curl, ant, rsync and the autotools: autoconf, automake, aclocal, libtoolize, pkgconfig
	On 64 bits linux systems you'll need the ia32-libs package
	With the latest Debian (multiarch), you need this:
		dpkg --add-architecture i386
		aptitude update
		aptitude install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386
3) run the Makefile script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
	$ make
4) To install the generated apk into a plugged device, run
	$ make install
5) (Optional) To generate a liblinphone SDK zip containing a full jar and native libraries, run
	$ make linphone-sdk
6) (Optional) To generate a libmediastreamer2 SDK zip containing a full jar and native libraries, run
	$ make mediastreamer2-sdk

To run the tutorials:
1) open the res/values/non_localizable_custom.xml file and change the value of the show_tutorials_instead_of_app to true.
2) compile again using make && make install.
3) /!\ don't forget to put it back to false to run the linphone application normally. /!\

To create an apk with a different package name, you need to edit the custom_rules.xml file:
1) look for the property named "linphone.package.name" and change it value accordingly
2) also update the values in the AndroidManifest file where the comment <!-- Change package ! --> appears
3) update the path to the sounds in the linphonerc-factory files in the res folders
4) run again the Makefile script by calling "make"


			   TROUBLESHOOTING
			*****************************

If you encounter troubles with the make clean target and you are using the 8e android ndk, the solution can be found here: https://groups.google.com/forum/?fromgroups=#!topic/android-ndk/3wIbb-h3nDU

If you built the app using eclipse, ensure you ran at least once the make command (see above steps 0 to 3) ! Else you'll have this exceptions:
FATAL EXCEPTION: main
java.lang.ExceptionInInitializerError
...
Caused by: java.lang.UnsatisfiedLinkError: Couldn't load linphone-armeabi-v7a: findLibrary returned null
...

			   CUSTOMIZATION
