And this is the code line in build.xml that mentioned

<taskdef resource="anttasks.properties" classpathref="android.antlibs" /> <property name="exe" value="" /> <property name="bat" value="" />

Before update I never see this error. How I fix this error.

Hello,
on which commit did you are on Linphone-Android ?

[jija]

I think it not important which commit. Because build.xml file not updates 2 years ago.

Since the migration to Gradle we don't use anymore ANT to build Linphone-Android.
