Unable to merge dex

Question

I have Android Studio Beta. I created a new project with compile my old modules but when I tried launching the app it did not launch with the message:

Error:         


        

Answer 1

One of possible root causes: duplicate transient dependencies that weren't properly handled by Android Studio import of multi-module projects. Check your list and remove them. For me, the fix was literally this:

--- a/project/module/build.gradle
+++ b/project/module/build.gradle
@@ -21,5 +21,4 @@ android {

     implementation project(':upstream-dependency-project')
