Hi @jobin0484, thanks for using our SDK.
It seems that there are some dependencies missing from your project. If you look at the mobilertc/build.gradle file in the sample app, you can find the required dependencies. Below I’ve included the dependencies required for the 5.7.1 release, but if you are on an earlier version they may be different.
configurations.create("default")
artifacts.add("default", file('mobilertc.aar'))
dependencies.add("default","androidx.security:security-crypto:1.1.0-alpha02")
dependencies.add("default","com.google.crypto.tink:tink-android:1.5.0")
dependencies.add("default","com.google.android.exoplayer:exoplayer-core:2.12.3")
dependencies.add("default","com.google.android.exoplayer:exoplayer-ui:2.12.3")
dependencies.add("default","androidx.swiperefreshlayout:swiperefreshlayout:1.0.0")
dependencies.add("default","androidx.appcompat:appcompat:1.0.0")
dependencies.add("default","androidx.constraintlayout:constraintlayout:1.1.3")
dependencies.add("default","com.google.android.material:material:1.2.0-alpha03")
dependencies.add("default","com.google.android:flexbox:2.0.1")
dependencies.add("default","androidx.multidex:multidex:2.0.0")
dependencies.add("default","com.google.code.gson:gson:2.8.1")
dependencies.add("default","com.github.bumptech.glide:annotations:4.11.0")
dependencies.add("default","com.github.bumptech.glide:glide:4.11.0")
Thanks!
