Note: You can only play audio and video to the standard output device. Currently, they are speakers or Bluetooth headsets. You cannot play audio files during phone calls. Basic The following types are used to play audio and video: MediaPlayer This is the main API for playing audio and video.

learning experience.Artificial Intelligence AI is a popular word in the 2016. Speech recognition and image classification are just two applications of this technology to the user, and AI machines meet or exceed human performance. There are many startups that apply AI and machine learning to new areas, as well as many open source projects, such as Google's Tensor Flow and Microsoft's cognitive Toolkit. Machine learning is a topic that is very relevant to mathematics, and for people who

Make sure that the microphone audio connector is completely inserted with the microphone interface. If the connection is loose, the microphone cannot be used due to poor contact.Note: Because the two-in-one audio co

Cause analysis of "S-for-machine assistant cannot be enabled during audio recording"The microphone and speaker are used when the S-machine assistant connects to the device. Therefore, when the microphone is in use or other peripheral devices (such as headphones or Bluetooth headsets) are connected, it cannot run.SolutionStops other applications from using microphones and speakers.Well, the above is an article for you in the editor about the

This defect is so incredible that when people find that they cannot record, they always think of "I won't operate", "Which button did I notice ?" , "There must be something to set", but this is indeed a design defect of Google and has always refused to correct it. Now, all the phone recording software is recorded through the microphone. The recording effect is that your voic

In February 2004, Symbian released the SYMBIAN8 0 version when it authorized LG and other companies. This version improves the performance of real-time systems and improves the compatibility of existing operating systems. In addition, Symbian OS 8.0 software tools improve the remote access control system function, using the regulator to eliminate mobile phone users to use value-added s

music. You can modify the current audio stream volume by receiving a key message from the volume control key. However, this is not necessary. Android provides a convenient setVolumeControlStream () method to automatically adjust the volume based on the specified audio stream. First, determine the audio stream that your application will use, and then set it as the current focus audio stream through the setVolumeControlStream method. This method should be called early and only once in the lifecyc
