$(document).ready(function(){
$("#record").on("click", function(){
alert("record start");
window.plugins.VoicePlugin.record(function(){alert("yo");},
function(){alert("yol");},

alert("record stop");
window.plugins.VoicePlugin.stoprecord(function(){},
function(){},

Android Plugin部分为
The Android Plugin part is

public static final String Record = "record";

@Override
public PluginResult execute(String action, JSONArray data, String callbackId) {
PluginResult result = null;
if(Record.equals(action)){ //data에 filename
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
try {
mRecorder.prepare();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
mRecorder.start();
} else if(Play.equals(action)){ //data에 filename
mPlayer = new MediaPlayer();
try {
mPlayer.setDataSource(mFileName);
mPlayer.prepare();
mPlayer.start();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
} else if(Stopplaying.equals(action)){
mPlayer.release();
mPlayer = null;
} else{
mRecorder.stop();
mRecorder.release();
mRecorder = null;
}
return null;
}
}
在Activity中记录，停止录制，播放和停止播放声音。如果我使用phonegap，因为它只是通过插件发送一些字符串， MediaRecorder 和 MediaPlayer 时间。我按下在html的记录按钮，创建 MediaRecorder 对象，但推动停止录制按钮不能停止 MediaRecorder 刚刚创建的对象。对于这个问题，有什么解决方案吗？
The point is, i should stay in an Activity that record, stop recording, play and stop playing the voice. If I use phonegap, since it just send some strings via plugin, the MediaRecorder and MediaPlayer object is created and destroyed each time. I push the record button which is in html, the MediaRecorder object is created, but pushing the stop recording button cannot stop the MediaRecorder object that is just created. Is there any solution for this problem?
推荐答案
使用Phonegap我录制语音和播放录音语音没有额外的插件。
我只能将Phonegap Media的插件转换为我的应用程序，如下所示：
With Phonegap I record voice and play recording voice without addition plugins. I only conect plugin of Phonegap Media to my app like this:
app/res/xml/config.xml
<plugin name="Media" value="org.apache.cordova.AudioHandler" />
app/AndroidManifest.xml
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

在Android设备上，PhoneGap媒体对象具有以下重要行为， href =http://software.intel.com/en-us/articles/media-sample-using-phonegap#id_android =nofollow> http://software.intel.com/en-us/articles / media-sample-using-phonegap＃id_android ）：
On Android devices, the PhoneGap media object has the following important behaviors that are not well documented (http://software.intel.com/en-us/articles/media-sample-using-phonegap#id_android):
- my_audio = new Media（'myRecording100.wav'， onMediaCallSuccess，
onMediaCallError）：当myRecording100.wav不存在时，
将创建文件; - my_audio.stopRecord（）：当调用stopRecord（）时，.wav
媒体文件被移动到/ sdcard文件夹。所以当检查以前的
是否记录了.wav存在，代码应该在/ sdcard文件夹下。如果
存在，它应该从
/sdcard/myRecording100.wav打开该文件。
希望这有助于你。
