我正在使用媒体记录器和以下代码保存音频文件:
public class AudioRecorder {
final MediaRecorder recorder = new MediaRecorder();
final String path;
/**
* Creates a new audio recording at the given path
*/
public AudioRecorder(String path) {
this.path = sanitizePath(path);
}
public static String sanitizePath(String path) {
if (!path.startsWith("/")) {
path = "/" + path;
}
if(path.endsWith("/")){
path = path + "/";
}
return path;
}
/**
* Starts a new recording.
*/
public void start() throws IOException {
// make sure the directory we plan to store the recording in exists
File directory = new File(path).getParentFile();
if (!directory.exists() && !directory.mkdirs()) {
throw new IOException("Path to file could not be created.");
}
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(path);
recorder.prepare();
recorder.start();
}
/**
* Stops a recording that has been previously started.
*/
public void stop() throws IOException {
recorder.stop();
recorder.release();
}
}
然后我使用以下代码调用这个类
int timeOfRecroding = AppPrefs.getSettingsAdditionalTimeOfRecording() * 60 * 1000;
ContextWrapper cw = new ContextWrapper(getApplicationContext());
File directory = cw.getDir("media", Context.MODE_PRIVATE);
final String pathAndName = AudioRecorder.sanitizePath(directory.getAbsolutePath() + "/LocRec.3gp");
final AudioRecorder audioRecorder = new AudioRecorder(pathAndName);
if(Constants.isTest){
showToast("Starting recording for [" + AppPrefs.getSettingsAdditionalTimeOfRecording() + "] minutes");
showToast("Recording to path: [" + pathAndName + "]");
}
然后当然使用 audioRecorder.start(); 和 audioRecorder.stop(); 做实际录音
录制完成后,我使用相同的 pathAndName 获取文件并将其作为电子邮件附件发送,使用以下代码获取文件
new File(new URI(AppPrefs.getInfoToSend(Constants.SERVICE_CODE_SEND_RECORDING, Constants.MESSAGE_TYPE_EMAIL)))
但这是抛出异常
URI is not absolute: /data/data/com.testrecoding.record/app_media/LocRec.3gp
感谢您的帮助,谢谢, Wassim
