Hi Ricky,

Thanks for the post. What are your Gradle settings? What is your Android SDK version?

You may refer to the following Gradle settings of our demo app:

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

    defaultConfig {
        applicationId "us.zoom.sdkexample2"
        minSdkVersion 16
        targetSdkVersion 28
		versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.0.0'
    implementation project(':commonlib')
    implementation project(':mobilertc')
}

Please make sure the SDK and the dependencies are matched, and the project is cleaned.

Hope this helps. Thanks!

Hi Carson,
I am facing same problem :java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/fragment/app/FragmentActivity;
But I do not want to migrate my project to androidx because I am already using many libraries so How can I resolve this issue …

Thanks

Hi Akash,

Thanks for using Zoom SDK. Upgrading to AndroidX is a requirement. The concern you are facing is well known online (not only for using SDKs), you may upgrade your project to AndroidX and use Jetifier to migrates libraries to rely on the equivalent AndroidX packages instead. You may find the following links useful:

Thanks!
