I am trying to update the microsoft-graph-api to 3.3.0 and everything works in the Emulator, but the real device is an Android 7.0 (API 24) and I get: com.android.tools.r8.a: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26)

Execution failed for task ':app:mergeExtDexDebug'.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Failed to transform azure-core-1.15.0.jar (com.azure:azure-core:1.15.0) to match attributes {artifactType=android-dex, dexing-enable-desugaring=true, dexing-incremental-transform=false, dexing-is-debuggable=true, dexing-min-sdk=24, org.gradle.category=library, org.gradle.libraryelements=jar, org.gradle.status=release, org.gradle.usage=java-runtime}. > Execution failed for DexingNoClasspathTransform: /Users/pmartinez/.gradle/caches/transforms-2/files-2.1/8cfc8780442b4f1e0ebead042ade0764/jetified-azure-core-1.15.0.jar. > Error while dexing.

The Readme from 3.3.0 says that developers trying to use it in <26 API could make it work using desugarizing, this is in my Gradle.app

compileOptions {
    // Flag to enable support for the new language APIs
    coreLibraryDesugaringEnabled true
    // Sets Java compatibility to Java 8
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
}
dependencies {
// To get features from Newer APIs
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.0.9'
    implementation "com.microsoft.identity.client:msal:2.+"
    implementation 'com.microsoft.graph:microsoft-graph:3.3.0'
    // Uncomment the line below if you are building an android application
    implementation 'com.google.guava:guava:29.0-android'
}

Any ideas on what I could do to keep the graph 3 and/or whats the microsoft-graph 2 minimum Android API?

You can try minifying the apk. It would remove unnecessary code and that method call may be unnecessary, even though graph api includes it. Here is an example:

buildTypes
{
  release
  {
    minifyEnabled true
  }
  debug
  {
    minifyEnabled true
  }
}
