Question

Answer 1

A change in the scope of the OkHttp Call constructor in 2.4 breaks our instrumentation. A fix for this has been merged into OkHttp and will be fixed in release 2.5: https://github.com/square/okhttp/pull/1687

In the mean time, the two workarounds are to either use OkHttp 2.3 or use 2.5.0-SNAPSHOT from the Sonatype snapshot repo, like so:

repositories {
    mavenCentral()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    ....
    compile 'com.squareup.okhttp:okhttp:2.5.0-SNAPSHOT'
    ....

I ran into the same problem. Basically the solution for me was to downgrade okhttp from version 2.4.0 to 2.2.0. It looks like a bug in the new relic lib. Take a look here: https://github.com/square/okhttp/issues/1680
