面对困难，而来自Android的发送MP3文件到服务器 [英] Facing difficulty while sending mp3 file from Android to Server
本文介绍了面对困难，而来自Android的发送MP3文件到服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我'试图从我的Android应用程序发送的MP3文件到服务器。我'用这种方法异步的android HTTP 送MP3文件。
这是我的code。
{尝试
params1.put（文件，新ByteArrayInputStream进行（MeetingFragment.mediafile））;
}赶上（FileNotFoundException异常E1）{
// TODO自动生成catch块
e1.printStackTrace（）;
} AsyncClientHandler.post（事件/ Uploadrecording / 5，params1，
新AsyncHtt presponseHandler（）{ @覆盖
公共无效onFailure处（INT状态code，
Throwable的错误，字符串的内容）{
// TODO自动生成方法存根
super.onFailure（状态code，错误的内容）;
Log.i（文件名，myFile.toString（））;
Toast.makeText（_contextfailiure推+ ProjectEventFragment.event.eve_id，Toast.LENGTH_SHORT）.show（）;
} @燮pressWarnings（德precation）
@覆盖
公共无效的onSuccess（INT状态code，
标题[]头，字符串的内容）{
// TODO自动生成方法存根
super.onSuccess（状态code，标题，内容）;
Toast.makeText（_context，成功推+ ProjectEventFragment.event.eve_id，Toast.LENGTH_SHORT）.show（）;
Log.i（Successpush，content.toString（））;
} }）;
我已经给出了正确的网址，我也为文件中获取价值。但它会成功的一部分。谁能帮我解决这个问题？如果您知道任何替代方法，那么请给我建议。先谢谢了。

I'am trying to send a mp3 file from my Android application to Server. I'am using this method android async http to send mp3 file.
This is my code.
try {
params1.put("file", new ByteArrayInputStream(MeetingFragment.mediafile));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
AsyncClientHandler.post("events/Uploadrecording/5", params1,
new AsyncHttpResponseHandler() {
@Override
public void onFailure(int statusCode,
Throwable error, String content) {
// TODO Auto-generated method stub
super.onFailure(statusCode, error, content);
Log.i("filename",myFile.toString());
Toast.makeText(_context, "failiure push"+ProjectEventFragment.event.eve_id, Toast.LENGTH_SHORT).show();
}
@SuppressWarnings("deprecation")
@Override
public void onSuccess(int statusCode,
Header[] headers, String content) {
// TODO Auto-generated method stub
super.onSuccess(statusCode, headers, content);
Toast.makeText(_context, "success push"+ProjectEventFragment.event.eve_id, Toast.LENGTH_SHORT).show();
Log.i("Successpush",content.toString());
}
});
I have given the correct URL and i also getting value for the file. But it is going to success part. Could anyone help me to solve this problem? If you know any alternate way then please suggest me. Thanks in advance.
public static byte[] mediafile;
public static String record_file=null
myAudioRecorder = new MediaRecorder();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
myAudioRecorder.setOutputFile(record_file);
mediafile = record_file.getBytes();
