This article focuses on how to capture a single frame of audio data on the Android platform. Before reading this article, it is recommended to read my previous article, "Android Audio Development (1): Fundamentals", because in the audio development process, often involves th

part of the application process, which communicates with other system processes through the binder service.In the process of analyzing the source code, it is important to grasp these two clues, so as not to feel confused.· HALFrom a design point of view, the hardware abstraction layer is an object that Audioflinger directly accesses. This illustrates two problems, on the one hand Audioflinger not directly invoke the underlying driver, on the other hand, Audioflinger upper layer (including the s

prevent multiple music apps from playing audio at the same time, Android uses audio focus to control the playback of audio. In this lesson, you can learn how to request audio focus, monitor the loss of audio focus, and how to res

Manage audio playback (from the Chinese version of the Android official training course (v0.9.5 )) If our applications can play audio, it is important for users to control the audio in their expected ways. To ensure a good user experience, we should allow the application to manage the current

Android is broadcast action_audio_becoming_noisy this intent notification.A good way to handle broadcasts is to dynamically register/unregister the broadcasts that you care about.

By default, the sampling rate of Android sound is fixed to 44.1 kHz, and the recording sampling rate is fixed to 8 kHz, therefore, the underlying audio device drivers only need to set these two fixed sampling rates. If the sampling rate transmitted from the upper layer does not match the sampling rate, the android framework layer performs resample processing on t
