Android Studio: Error: Program type already present: androidx.core.graphics.PathSegment

Question

I use Android Studio 3.3 Canary 8. I created default project and then I tried run the project. But I had seen following stacktrace:

AGPBI: {"kind":"error","text":"Program type already present: androidx.core.graphics.PathSegment","sources":[{}],"tool":"D8"} Task :app:buildInfoGeneratorDebug FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: Learn how to resolve the issue at https://developer.android.com/studio/build/dependencies#duplicate_classes.

Answer 1

Seems like a bug on recent Android stuff, which occurs even if you create a new project.

I've reported about this recently here .

The workaround, which I've found by choosing to migrate to Android-x, is this:

implementation 'androidx.core:core-ktx:1.0.0-rc02'

instead of this generated line :

implementation 'androidx.core:core-ktx:0.3'

Answer 2

Replace

implementation 'androidx.core:core-ktx:0.3'

with

implementation "androidx.core:core-ktx:1.0.0"// Updated version

Answer 3

for this error you have to update this dependency to latest

implementation 'androidx.core:core-ktx:0.3'
