If you implement an audio file playback, the simplest way to provide the ability to play audio files in your application is to take advantage of the features of the built-in "music" app-even if you use the system's own or installed music player to play the specified audio file.This example is relatively simple, the fol

Android microphone audio sampling and usage Some codes of Android phone microphone sampling are found online. Sample results and functional code of your app: 1. In some apps, You need to obtain and use the audio input of the microphone, for example, a hot skirt; 2. Sampling

calculates the average value. However, the precondition is that the number of channels and the sample value of the two files must be the same. We have also explained the functions of the number of channels and the sample value before, so we can infer that if the sample value is 8 bits and 16 bits, we need to convert byte to short and then overlay the average number; if a single channel needs to be combined with a dual channel, the write algorithm is added to the first half or the second half. T

to display the video preview. The remaining code is basically the same as the recorded audio code: The instance uses MediaRecorder to record a video: 1. RecordVideo class: Package com. jph. recordvideo; import java. io. file; import android. app. activity; import android.

Some Android AudioRecord models cannot collect audio, androidaudiorecord During the first Android development, I realized such profound version differences for the first time.My AudioRecord code was successfully tested in Samsung S5670.Xiaomi, duowei D210T test failed. The error message is as follows:04-01 12:58:44. 368: E/AudioRecord (19808): cocould not get

Given the ability to play an audio file, the simplest way to provide the ability to play audio files in your application is to take advantage of the features of the built-in "music" app-even if you use the system's own or installed music player to play the specified audio file.This example is relatively simple, the fol

On the audio and video calls in the process of minimizing the implementation of this function, similar articles on the network, but it seems to have not seen the clearer explanation, here because the project needs to achieve such a function, today I recorded it down, on the one hand for later use to facilitate their own access, On the one hand also give people who need to provide a train of thought, let everyone less detours. Here I also refer to some

Android Phone Microphone Sampling Some code is found on the Internet, specifically do not remember.Use the sample result and the function code of your own app:1. In some apps, the audio input of the microphone will need to be used, such as a very hot blown skirt;2.

The previous article has introduced the Android interface of the introduction of the technology, I believe that everyone after reading and follow the practice, the common layout and view will have a certain understanding, and then no longer emphasize the introduction of the interface, but for the specific common features to unfold. This article will introduce the use of MediaPlayer. MediaPlayer can play audio
