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

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.

Gradle Setup
------------

```
$ cat local.properties
sdk.dir=PATH_TO_ANDROID_HOME/sdk
org.gradle.caching=true
```

Running Android Tests
---------------------

$ ANDROID_SDK_ROOT=PATH_TO_ANDROID_HOME/sdk ./gradlew :android-test:connectedCheck -PandroidBuild=true
