Hi guys, I want to raise the following question - what we should recommend
plugin developers to avoid 'Multiple dex files defined' issue on Android, for
example [3]
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dex.DexException: Multiple dex files define
Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat$AccessibilityServiceInfoVersionImpl;
To reproduce this problem you can add both Facebook [1] and PushPlugin[2] and
then build android platform.
This happens due to we still use jars to add plugin dependencies, but there are
several very popular among them (like android-support, gson) so we bring the
same dependencies several times so build fails.
I think we should start recommending people to start adding
utility/common/popular dependencies via corresponding gradle configuration (not
using libs folder) as the only way to support multiple plugins which could rely
on the same dependency. In this case gradle will be able to handle this
situation correctly using its smart Dependency Management/Versioning logic [4].
For example,
<source-file src="src/android/com/plugin/android-support-v13.jar"
target-dir="libs/" />
->
<framework src="com.android.support:support-v13:21.0.0" />
Disadvantage of this approach is that Ant build won't be supported (I know some
tricky/more complex way to correctly support both Ant and Gradle but I don't
think it is worth adding more complexity for plugins developers just to
continue supporting Ant).
Guys, any recommendations/thoughts how we should proceed in this situation?
Maybe someone has better solution for this problem?
