Device classification

Quickplay player determines the capability class of the Android device based on hardware specifications and codec support, and classifies the device into 3 categories: HIGH_END, MID_RANGE, and LOW_END.

Get device classification

To get device classification, you can use the DevicePerformanceClassifier class.

DevicePerformanceClassifier.getDeviceCapabilities()

It provides the DeviceCapability classification as follows:

Classification	Detail
HIGH_END	Flagship models.
MID_RANGE	Good performance mid-range models.
LOW_END	Entry-level models with modest processors and others.

It also provides other supportive APIs to get device specifications.

// Device RAM as Long in MB
DevicePerformanceClassifier.getTotalRAM()

// The number of CPU cores
DevicePerformanceClassifier.getCPUCores()

/**
 * The approximate per-application memory class of the current
 * device. This gives you an idea of how hard a memory limit you should
 * impose on your application to let the overall system work best. The
 * returned value is in megabytes; the baseline Android memory class is
 * 16 (which happens to be the Java heap limit of those devices); some
 * devices with more memory may return 24 or even higher numbers.
 */
DevicePerformanceClassifier.getMemoryClass()

// Returns information for secure AVC decoder.
DevicePerformanceClassifier.getAvcDecoderInfo()

// Returns information for secure HEVC decoder.
DevicePerformanceClassifier.getHevcDecoderInfo()

// Retrieves the maximum supported instances and resolution for secure H.264 and H.265 video decoders.
DevicePerformanceClassifier.getMaxSupportedSecureDecoderInstances()
