Error:com.android.builder.dexing.DexArchiveBuilderException: Failed to process guava-21.0.jar Android 3.1 Dev Channel
I had the same issue in react-native project,
the below lines worked for me,
compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8}
Update your Guava version
Guava 21 is Java 8 only.
Update your gradle to Guava version 27.0.1-android
, which is compatible with Android:
Gradle 4.6+:
dependencies { implementation 'com.google.guava:guava:27.0.1-android'}
Previous Gradle versions:
dependencies { compile 'com.google.guava:guava:27.0.1-android'}
I had same problem and I solved it cleaning project and rebuilding it.
In Android Studio go to Build --> Clean Project and after, Build --> Rebuild Project
Hope it helps
