Performance class

Performance class is a standard first introduced in Android 12. A performance class defines a set of device capabilities that goes beyond Android's baseline requirements.

Each version of Android has its own corresponding performance class, which is defined in that version's Android Compatibility Definition Document (CDD). The Android Compatibility Test Suite (CTS) verifies the CDD requirements.

Each Android-powered device declares the performance class that it supports. Developers can find the device's performance class at runtime and provide upgraded experiences that take full advantage of the device's capabilities.

To find a device's performance class level, use the Jetpack Core Performance library. This library reports the device's media performance class (MPC) level as declared in the build version information or based on data from Google Play services.

Start by adding a dependency for the relevant modules in your gradle file:

// Implementation of Jetpack Core library.
implementation("androidx.core:core-ktx:1.12.0")
// Enable APIs to query for device-reported performance class.
implementation("androidx.core:core-performance:1.0.0")
// Enable APIs to query Google Play services for performance class.
implementation("androidx.core:core-performance-play-services:1.0.0")

// Implementation of Jetpack Core library.
implementation 'androidx.core:core-ktx:1.12.0'
// Enable APIs to query for device-reported performance class.
implementation 'androidx.core:core-performance:1.0.0'
// Enable APIs to query Google Play services for performance class.
implementation 'androidx.core:core-performance-play-services:1.0.0'

Then, create an instance of a DevicePerformance implementation, such as PlayServicesDevicePerformance, in the onCreate() lifecycle event of your Application. This should only be done once in your app.

import androidx.core.performance.play.services.PlayServicesDevicePerformance

class MyApplication : Application() {
  lateinit var devicePerformance: DevicePerformance

  override fun onCreate() {
    // Use a class derived from the DevicePerformance interface
    devicePerformance = PlayServicesDevicePerformance(applicationContext)
  }
}

import androidx.core.performance.play.services.PlayServicesDevicePerformance;

class MyApplication extends Application {
  DevicePerformance devicePerformance;

  @Override
  public void onCreate() {
    // Use a class derived from the DevicePerformance interface
    devicePerformance = new PlayServicesDevicePerformance(applicationContext);
  }
}

You can then retrieve the mediaPerformanceClass property to tailor your app's experience based on the device's capabilities:

class MyActivity : Activity() {
  private lateinit var devicePerformance: DevicePerformance
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    // Note: Good app architecture is to use a dependency framework. See
    // https://developer.android.com/training/dependency-injection for more
    // information.
    devicePerformance = (application as MyApplication).devicePerformance
  }

  override fun onResume() {
    super.onResume()
    when {
      devicePerformance.mediaPerformanceClass >= Build.VERSION_CODES.VANILLA_ICE_CREAM -> {
        // MPC level 35 and later.
        // Provide the most premium experience for the highest performing devices.
      }
      devicePerformance.mediaPerformanceClass == Build.VERSION_CODES.UPSIDE_DOWN_CAKE -> {
        // MPC level 34.
        // Provide a high quality experience.
      }
      else -> {
        // MPC level 33, 31, 30, or undefined.
        // Remove extras to keep experience functional.
      }
    }
  }
}

class MyActivity extends Activity {
  private DevicePerformance devicePerformance;
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Note: Good app architecture is to use a dependency framework. See
    // https://developer.android.com/training/dependency-injection for more
    // information.
    devicePerformance = ((MyApplication) getApplication()).devicePerformance;
  }

  @Override
  public void onResume() {
    super.onResume();
    if (devicePerformance.getMediaPerformanceClass() >= Build.VERSION_CODES.VANILLA_ICE_CREAM) {
      // MPC level 35 and later.
      // Provide the most premium experience for the highest performing devices.
    } else if (devicePerformance.getMediaPerformanceClass() == Build.VERSION_CODES.UPSIDE_DOWN_CAKE) {
      // MPC level 34.
      // Provide a high quality experience.
    } else {
      // MPC level 33, 31, 30, or undefined.
      // Remove extras to keep experience functional.
    }
  }
}

Performance class levels are forward-compatible. A device can upgrade to a newer platform version without updating its performance class. For example, a device that initially supports performance class 33 can upgrade to Android 14 and continue to report it supports performance class 33 if it doesn't meet the performance class 34 requirements. This allows grouping devices together without relying on a particular Android version.

Media Performance Class 35

MPC 35 was introduced in Android 15 and builds on the requirements introduced in MPC 34. The specific MPC 35 requirements are published in the Android 15 CDD. In addition to increased requirements for items from MPC 34, the CDD specifies requirements in the following areas:
