The Okhttp 2.6.0 library does not work in versions prior to Android 5. In versions prior to Lollipop always fires the exception:

Exception

android lollipop okhttp

  • I’m using the same version as you! And I haven’t had any problems so far! The lowest version we tested here is 4.0.3. According to the documentation: Okhttp Supports Android 2.3 and above. For Java, the minimum requirement is 1.7.

  • This is the weirdest because I have another app that works well too. Suddenly stopped working. It seems to me that it was after the update of Android Studio and Build Tools.

  • I had a problem with appcompat-v7. I climbed the version and it could not find... To solve, I removed Android Studio, downloaded again and reinstalled! Then I’m cool!

The problem is that you failed to add the Okio, another library that the OkHttp needs to work, according to official documentation:

You’ll also need Okio, which Okhttp uses for fast I/O and resizable buffers. Download the Latest JAR.

Add the Okio in his build.gradle:

compile 'com.squareup.okio:okio:1.6.0'

  • I already added. But the same exception is thrown.

  • @Luídne already tried to give one clear project?

  • I’ve tried that too.
