1. Add an Emulator named `pixel5`, if you don't already have one

```
$ sdkmanager --install "system-images;android-29;google_apis;x86"
$ echo "no" | avdmanager --verbose create avd --force --name "pixel5" --device "pixel" --package "system-images;android-29;google_apis;x86" --tag "google_apis" --abi "x86"
```

2. Run an Emulator using Android Studio or from command line.

```
$ emulator -no-window -no-snapshot-load @pixel5
```

    adapter. (thanks kwuollett)
 *  Add a media type class to OkHttp.
 *  Change custom header prefix:

    ```
    X-Android-Sent-Millis is now OkHttp-Sent-Millis
    X-Android-Received-Millis is now OkHttp-Received-Millis
    X-Android-Response-Source is now OkHttp-Response-Source
    X-Android-Selected-Transport is now OkHttp-Selected-Transport
    ```
 *  Improve cache invalidation for POST-like requests.

      - name: Gradle cache
        run: ./gradlew :android-test:test

      - name: AVD System Image Cache
        uses: actions/cache@v5
        id: avd-cache
        with:
          key: avd-${{ runner.os }}-${{ matrix.api-level }}-${{ matrix.api-level >= 30 && 'x86_64' || 'x86' }}
          path: |
            ~/.android/avd/*
            ~/.android/adb*
            # Added the actual system image path

Advanced Profiling
------------------

Android Studio’s Advanced Profiling feature rewrites OkHttp bytecode for instrumentation.
Unfortunately it crashes on OkHttp 4.x’s bytecode. Until [Google’s bug][advanced_profiling_bug] is
fixed you must disable advanced profiling in Android Studio.
