Qualcomm Enhanced Software Development Kit (QESDK) APIs provide access to QTI-specific
      hardware and software capabilities. Handset manufacturers and third-party Android application
      developers with a valid license key can take advantage of the QESDK library and Snapdragon
      value added features offered by the SDK.

This document is intended for handset manufacturers and application vendors who integrate
      QESDK with their application. It provides information on setting up the SDK and an overview of
      the sample application that demonstrates SDK features.

Review the [Prerequisites to use QESDK features](https://docs.qualcomm.com/doc/80-PV345-88/topic/Prerequisites_to_use_QESDK_features.html) and see if you have
      everything necessary to get started.

If you do, make sure you've [setup QESDK](https://docs.qualcomm.com/doc/80-PV345-88/topic/Set_up_QESDK.html) and then start
      exploring the [available QESDK
        features](https://docs.qualcomm.com/doc/80-PV345-88/topic/QESDK_sample_application_features_topichead.html), including the [Modem features](https://docs.qualcomm.com/doc/80-PV345-88/topic/modem_features.html), [Sensor features](https://docs.qualcomm.com/doc/80-PV345-88/topic/sensor_features.html), [Performance features](https://docs.qualcomm.com/doc/80-PV345-88/topic/performance_features.html), or [Precise positioning features](https://docs.qualcomm.com/doc/80-PV345-88/topic/precise_positioning_features.html).
