Build Linphone Android for i.MX6

[#1]

Linphone is an internet phone or Voice Over IP phone (VoIP).

• With Linphone you can communicate freely with people over the internet, with voice, video, and text instant messaging.
• Linphone makes use of the SIP protocol, an open standard for internet telephony. You can use Linphone with any SIP VoIP operator, including our free SIP audio/video service.
• Linphone is free software (or open-source), you can download and redistribute it freely.
• Linphone is available for desktop computers: Linux, Windows, Mac OSX, and for mobile phones: Android, iPhone, Blackberry.

Linphone-android is a good example to show the integration of Java code based on Android SDK with native CODEC, network protocols. Not like XBMC-Android that is almost total c++/c project.

Perform the following steps to build a linphone-android project:

1. git clone git://git.linphone.org/linphone-android.git --recursive

2. sudo apt-get install autoconf automake libtool pkg-config

3. "cd" to the root of "git clone" : cd /home/user/linphne-android // wherver git'ed linphone-android is

4. export PATH=/home/user/android-ndk:$PATH //wherever your android-ndk, android-sdk tools, and platform-tools, and ANT are stored in.

            For example on my PC.

     export PATH=/home/alanz/android-ndk-r8d:/home/alanz/android-sdk-linux/tools:/home/alanz/android-sdk-linux/platform-     tools:/home/alanz/bin/apache-ant-1.8.4/bin:$PATH

            Note: PATH contains the ndk, sdk, and ant.

5. Make sure the network is working, then execute "./prepare_sources.sh" at the linphone-android root

6. Then, execute "/home/alanz/android-ndk-r8d/ndk-build", it will take a while to be finished

7. Modify Makefile as following example, modify it accordingly.

     NDK_PATH=/home/alanz/android-ndk-r8d

     SDK_PATH=/home/alanz/android-sdk-linux/tools

     SDK_PLATFORM_TOOLS_PATH=/home/alanz/android-sdk-linux/platform-tools

     .....................

     generate-libs:

          $(NDK_PATH)/ndk-build ....... (remove -j$(NUMCPUS) by the end of this command line)

8. execute "make", after finish, the apk file can be found under bin/ subdirectory.

Hi thanks for your help but i am getting below error in 5th step, while executing "./prepare_sources.sh"

Main problem is, when with these errors, i complete all steps and move ahead and import code in eclipse, run then i get java.lang.NoClassDefFoundException in GCMRegister class if i comment this code then same error for LinphoneActivity.java. please guide how i can get rid of this error and successfully run and test this code. Thanks in Advance.

There is no prepare_sources.sh file in the latest linphone-android sources. I was able to build linphone according to the README directions of the linphone-android git sources and run it on an android phone and it works

[zhangjay]

Is there the Linphone for Android using the CPU's hardware encoder?

If I use it on imx53 or imx6, it will use VPU?

[varsmolta]

It will not use the VPU. You will have to write a plugin which uses the hardware encoder. You could try using gstreamer appsrc plugin and combining that with a new mediastreamer2 plugin

Hi,

Do anybody have idea regarding whether we can use i.MX6 for designing Analog telephone adaptors? What kind of SW application we need to implement on i.MX6D?
