Deploy Android App

Here is how you can deploy an Android App via:

• APK 
• Google Store

Since you want to share your app in two different ways—directly (as a file) and professionally (via the store)—you will need to go through two slightly different build processes in Android Studio.

Here is the step-by-step guide for both methods.

Important Prerequisite: The Keystore

Before you build anything for the public, you must create a Keystore. This is a digital file that acts as your "signature." It proves you are the original creator of the app.

CRITICAL WARNING: Do not lose your Keystore file or forget its password.

If you lose it, you will never be able to release an update for your app on the Play Store again. Back it up to the cloud or a USB drive immediately.

Method 1: Deploy as an APK (Direct Sharing)

Best for: Sending to friends, internal company use, or direct download from a website.

This creates a standalone file (.apk) that anyone can install on their phone, provided they enable "Install from Unknown Sources" in their settings.

1. Open Android Studio: Go to the top menu bar.

2. Navigate: Click Build > Generate Signed Bundle / APK.

3. Select APK: Choose APK (not Bundle) and click Next.

4. Create Keystore:

• Click Create new... under the "Key store path".

• Choose a location on your computer to save the file.

• Create a strong password for both the Keystore and the Key.

• Fill in the "Certificate" details (First and Last name is usually enough).

• Click OK.

1. Build:

• Select the keystore you just made.

• Click Next.

• Select release (not debug).

• Check the boxes for V1 (Jar Signature) and V2 (Full APK Signature).

• Click Create (or Finish).

1. Locate File: Once the build finishes, a popup will appear. Click locate. You will see a file named app-release.apk. You can now email or WhatsApp this file to anyone!

Method 2: Deploy to the Google Play Store

Best for: Reaching a wide audience, automatic updates, and professional trust.

Google no longer uses .apk files for the store. They now require an Android App Bundle (.aab). This is a more efficient format that makes the app smaller for users to download.

Phase A: Generate the Bundle

1. Navigate: Click Build > Generate Signed Bundle / APK.

2. Select Bundle: Choose Android App Bundle and click Next.

3. Use the Same Keystore: Select the same keystore file you created in Method 1. (Always use the same key for the same app).

4. Build: Select release and click Finish.

5. Locate: This will generate a .aab file. Do not send this to phones; this file is only for Google's servers.

Phase B: The Google Play Console

1. Register: Go to the Google Play Console. You must pay a one-time $25 USD registration fee.

2. Create App: Click Create App and fill in the details (Name, Language, Free/Paid).

3. Upload Bundle: Go to Production (or "Testing" if you want a beta test first) > Create New Release. Upload your .aab file here.

4. Store Listing: You will need to provide:

• Screenshots: At least 2 for phone, and usually a 7-inch tablet screenshot.

• Feature Graphic: A 1024x500 banner image.

• Description: A short and long description of your inventory app.

• Privacy Policy: Since your app uses the Camera, Google requires a link to a privacy policy explaining how you handle that data.1

  
  

1. Review: Once you submit, Google will review the app (usually takes 1–4 days). Once approved, it is live for the world!

Summary: Which should you use?

Next Step

Since your app uses the camera, the Privacy Policy requirement for the Play Store can be tricky if you don't have a website.
