When building a mobile application, it's important that you always test your application on a real device before releasing it to users. This page describes how to set up your development environment and Android-powered device for testing and debugging on the device.

You can use any Android-powered device as an environment for running, debugging, and testing your applications. The tools included in the SDK make it easy to install and run your application on the device each time you compile. You can install your application on the device directly from Android Studio or from the command line with ADB. If you don't yet have a device, check with the service providers in your area to determine which Android-powered devices are available.

If you want a SIM-unlocked phone, then you might consider a Nexus phone. To purchase a Nexus phone, visit the Google Play store.

Note: When developing on a device, keep in mind that you should still use the Android emulator to test your application on configurations that are not equivalent to those of your real device. Although the emulator does not allow you to test every device feature (such as the accelerometer), it does allow you to verify that your application functions properly on different versions of the Android platform, in different screen sizes and orientations, and more.

Enabling On-device Developer Options

Android-powered devices have a host of developer options that you can access on the phone, which let you:

To access these settings, open the Developer options in the system Settings. On Android 4.2 and higher, the Developer options screen is hidden by default. To make it visible, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options at the bottom.

Setting up a Device for Development

With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator. Before you can start, there are just a few things to do:

  1. Verify that your application is "debuggable" in your manifest or build.gradle file.

    In the build file, make sure the debuggable property in the debug build type is set to true. The build type property overrides the manifest setting.

    android {
        buildTypes {
            debug {
                debuggable true
            }
    

    In the AndroidManifest.xml file, add android:debuggable="true" to the <application> element.

    Note: If you manually enable debugging in the manifest file, be sure to disable it in your release build (your published application should usually not be debuggable).

  2. Enable USB debugging on your device.
  3. Set up your system to detect your device.

Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or higher.

When plugged in over USB, you can verify that your device is connected by executing adb devices from your SDK {@code platform-tools/} directory. If connected, you'll see the device name listed as a "device."

If using Android Studio, run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s). Select the device upon which you want to install and run the application.

If using the Android Debug Bridge (adb), you can issue commands with the -d flag to target your connected device.

USB Vendor IDs

This table provides a reference to the vendor IDs needed in order to add USB device support on Linux. The USB Vendor ID is the value given to the ATTR{idVendor} property in the rules file, as described above.
