Android project throws FileAnalysisException in onCreate method in Main Activity when adding OkHttp library

Question

I've created an Empty Views Activity project in Android Studio, but as soon as I add the dependency in build.gradle.kts and try to launch the app, it throws an exception (see output). No code is added to MainActivity.kt.

The dependency section of my build.gradle.kts looks like this:

dependencies {
 implementation("com.squareup.okhttp3:okhttp:5.1.0")
 implementation(libs.androidx.core.ktx)
 implementation(libs.androidx.appcompat)
 implementation(libs.material)
 implementation(libs.androidx.activity)
 implementation(libs.androidx.constraintlayout)
 testImplementation(libs.junit)
 androidTestImplementation(libs.androidx.junit)
 androidTestImplementation(libs.androidx.espresso.core)
}

The output:

org.jetbrains.kotlin.util.FileAnalysisException: While analysing /home/myuser/AndroidStudioProjects/WebSocketTest01/app/src/main/java/com/mydomain/websockettest01/MainActivity.kt:20:5: java.lang.IllegalArgumentException: source must not be null

Sometimes I get it to build, but as soon as I add the import import okhttp3.* into MainActivity.kt, I get the same error when trying to run it.

I have experienced the same error when trying to use another library for MQTT. As soon as I add the dependency, I get this error.

• Mike M.: Same thing here, apparently: stackoverflow.com/q/79772930.
• Beavis: Thanks. Good to see I'm not alone at least.

Answer 1

I just fixed this issue by reverting to okhttp 4.12.0. So using com.squareup.okhttp3:okhttp:4.12.0.

Another fix (even better) is updating the core dependencies in the libs.versions.tom:

kotlin = "2.2.20"
composeBom = "2025年09月01日"
okhttp = "5.1.0"

NOTE: For that second fix, you must first apply the Replace with new library catalog declaration for okhttp quickfix from the lightbulb button.

This will work perfectly after a ./gradlew clean
