# Android test build

> This page is about FlutterFlow (the app builder you use by describing your app), not FlutterFlow Studio.

Prepare an Android test build of your app in Releases, then download it and install it on your Android phone.

Prepare an Android [test build](https://docs.flutterflow.io/ffx/glossary#test-build) of your app and install it on your own Android phone.

You need an [App ID](https://docs.flutterflow.io/ffx/app-details#app-id). FlutterFlow builds from your app, not a thread, so [push](https://docs.flutterflow.io/ffx/push) your changes first.

## Prepare the Android app {#prepare-the-android-app}

Use the **Android app** row in **On your phone** to prepare an installable test build:

1. Open **Releases** and select **On your phone**.
2. In the **Android app** row, select **Prepare Android app**.
3. Wait until the row shows **Ready** and the version number, such as **Ready · 0.1**.

If your app is connected to Google Play, FlutterFlow also sends the build to your Google Play testing track. See [Send to testers](https://docs.flutterflow.io/ffx/send-to-testers).

## Install the app {#install-the-app}

When the build is ready, **On your phone** shows how to download and install it:

1. Download the build to your Android phone:
   - **From a computer:** scan the QR code with your Android phone's camera.
   - **On your Android phone:** select **Download Android app (.apk)**.
2. Open the downloaded file on your Android phone.
3. If Android prompts you, allow your browser to install apps, and then tap **Install**.

## Ask the agent for the Android app {#ask-the-agent}

You can also ask [the agent](https://docs.flutterflow.io/ffx/glossary#the-agent) in a thread to build the Android app:

> Example request: "Build the Android app so I can install it on my phone."

The agent builds your app's pushed state, so it asks you to push any unpushed changes first. An **Android app** **Version** card tracks the build. When the build finishes, select **Show the code** on the card to open **On your phone** and install it, or select **Open in Releases** to view it in **Releases**.

## Troubleshooting {#if-something-goes-wrong}
