    implementation 'androidx.core:core-ktx:1.6.0'
    implementation 'androidx.appcompat:appcompat:1.3.1'
    implementation 'com.google.android.material:material:1.4.0'

    implementation 'com.android.volley:volley:1.2.1'
    implementation 'com.loopj.android:android-async-http:1.4.9'
}

Edited

I changed minsdk version but it showed another error, also add uses-sdk tools like this error, but got same error.

CodePudding user response：

This problem occur when you are adding two dependencies that includes the same classes. And I think the accused one should be this braintreepayments dependency, so I recommend updating

  implementation 'com.braintreepayments.api:drop-in:3.3.0'

TO a newer version

  implementation 'com.braintreepayments.api:drop-in:5.2.2'

And for sure you have already added the mven repo to your project gradle file.

repositories {
    maven {
        url "https://cardinalcommerceprod.jfrog.io/artifactory/android"
        credentials {
            username 'braintree_team_sdk'
            password 'AKCp8jQcoDy2hxSWhDAUQKXLDPDx6NYRkqrgFLRc3qDrayg6rrCbJpsKKyMwaykVL8FWusJpp'
        }
    }
}

EDITED

Don't forget to set the min sdk version 21 or above

defaultConfig {
        ...
        minSdkVersion 21
        ...   
    }

and remove this line if exists in the manifest

<uses-sdk android:minSdkVersion="16"/>
