How to Run the Android App on a Real Device?

Running an Android app on a real device can be very helpful for testing the app's behavior in a real-world scenario. Here's how you can run your Android app on a real device using Android Studio:

1. Prepare your Android Device:

  1. Enable Developer Options:

    • Go to Settings > About phone.
    • Tap the Build number entry seven times. After a few taps, you'll see a toast message that says "You are now a developer!".

  2. Enable USB Debugging:

    • Go to Settings > System > Advanced > Developer options.
    • Toggle on USB Debugging.

2. Connect your Device:

  • Using a USB cable, connect your Android device to your computer.
  • When you connect for the first time, a dialog box might appear on the device asking for permission to allow USB debugging. Check the "Always allow from this computer" box and tap OK.

3. Run the App from Android Studio:

  1. Open your Android project in Android Studio.
  2. Ensure that your device is detected. You should see the device name and its Android version in the target device dropdown near the top of the Android Studio window.
  3. Click the green Run button (a play icon) or press Shift + F10. Android Studio will build the app and install it on your device.
  4. Once the installation is complete, the app will automatically start on the device.

4. Check Log Output (Optional):

  • You can monitor the log output of your app in real-time. In Android Studio, open the Logcat window by navigating to View > Tool Windows > Logcat.

5. Disconnect Safely:

  • Once you're done, it's good practice to eject/unmount your device from your computer before disconnecting the USB cable.

Notes:

  • Make sure the appropriate drivers are installed if you're using a Windows machine. Usually, these drivers get installed automatically when you connect the device, but some manufacturers require manual installation.

  • Ensure your device's Android version is compatible with the minSdkVersion specified in your app's build.gradle file.

Running your app on a real device provides the advantage of testing features that might not be fully functional on an emulator, such as device-specific hardware features, sensors, camera functionality, and more.
