In addition to recording audio, mediarecoder can also be used to record a video. The procedure is basically the same as that of the recorded audio. However, to record a video, you must not only collect the sound but also the image, you need to use surfaceview to preview and display the image. The following is a simple example. The Code is as follows: Activity: Package COM. home. recordvideo; import Java. io. file; import android. app. activity; import android. media. mediarecorder; import androi

Objective:In fact, recording in Android can be recorded with Mediarecord, the operation is relatively simple. However, the audio cannot be processed. Consider that the project is done in real-time voice can only select Audiorecord for recording.This article is a review of Audiorecord: Public classAudiorecordmanager { Public Static FinalString TAG = "Audiorecordmanager"; PrivateAudiorecord Mrecorder; PrivateDataOutputStream dos; PrivateThread Recordthr
