pipeline status

Linphone is a free VoIP and video softphone based on the SIP protocol.


To build liblinphone for Android, you must:

  1. Download the latest Android sdk with platform-tools and tools updated to latest revision, then add both 'tools' and 'platform-tools' folders in your path and the android-sdk folder to ANDROID_HOME environment variable.

  2. Download the latest Android NDK from google and add it to your path (no symlink !!!) and ANDROID_NDK environment variable.

  3. Install yasm, nasm (For OpenH224 support only), python, pkg_config, doxygen, graphviz and cmake(>=3.12).

  • 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
  1. Run ./ in the top level directory. This will configure the build and generate a Makefile in the top level directory. Some options can be passed to choose what you want to include in the build and the platforms for which you want to build. Use ./ --help to see what these options are.

  2. Run the Makefile script in the top level directory, make.

  3. (optional) To install the generated apk into a plugged device, run make install.

  4. (optional) To generate a liblinphone SDK zip containing a full jar and native libraries, run make liblinphone-android-sdk

  5. (optional) To generate a libmediastreamer2 SDK zip containing a full jar and native libraries, run make mediastreamer2-sdk

  6. (optional) To generate a signed apk to publish on the Google Play, run make release. Make sure you filled the values for, store file, store password, key alias and key password to correctly sign the generated apk:


If you don't, the passwords will be asked at the signing phase.

  1. (optional) Once you compiled the libraries succesfully with 'make', you can reduce the compilation time using 'make quick': it will only generate a new APK from java files.

To create an apk with a different package name

You need to edit the build.gradle file:

  1. look for the function named "getPackageName()" and change it value accordingly
  2. also update the values in the AndroidManifest file where the comment appears
  3. change the package name also in the files: res/xml/syncadapter.xml, res/xml/contacts.xml and res/values/non_localizable_custom where appears
  4. run again the Makefile script by calling "make"

To run the liblinphone test suite on android

Simply run make liblinphone_tester. This will be build everything, generate an apk, and install it on the connected device if any.

You can speed up the compilation by using ccache (compiler cache, see Give the "-DCMAKE_C_COMPILER_LAUNCHER=ccache -DCMAKE_CXX_COMPILER_LAUNCHER=ccache" options to the script.



To enable firebase in Linphone, just add your 'google-service.json' in project root, add your key at 'push_sender_id' and add 'firebase' at 'push_type' in 'res/values/non_localizable_custom.xml' Be sure to have all services for Firebase in your 'AndroidManifest.xml'


If you encounter the following issue:

E/dalvikvm( 2465): dlopen("/data/app-lib/org.linphone-1/") failed:
Cannot load library: soinfo_relocate(linker.cpp:975): cannot locate symbol "rand" referenced
by ""

It's because you have installed the android-21 platform (which is chosen automatically because it's the most recent) and you deployed the apk on a android < 5 device.

To fix this, in the Makefile, force ANDROID_MOST_RECENT_TARGET=android-19.

If you encounter troubles with the make clean target and you are using the 8e android ndk, the solution can be found here.

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:

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load linphone-armeabi-v7a: findLibrary
returned null


The build options are to be passed to the script. For example to enable the x264 encoder give the "-DENABLE_X264=YES" to

The available options can be listed with the ./ --list-features
