我从soundcloud获取音频，我也可以在我的应用中传输该音频，现在问题是如何将音频上传到soundcloud，然后我想将ID发送到我的服务器端
我的要求是使用上传按钮我想从外部存储目录中获取文件，然后我想发送上传音频。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mDbHelper = new GinfyDbAdapter(this);
setContentView(R.layout.upload_audiogallery);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
upload = (ImageButton) findViewById(R.id.btnupload);
btnstop = (Button) findViewById(R.id.btnstop);
//Bundle extras = getIntent().getExtras();
token = (Token) this.getIntent().getSerializableExtra("token");
wrapper = new ApiWrapper("3b70c135a3024d709e97af6b0b686ff3",
"51ec6f9c19487160b5942ccd4f642053",
null,
token);
//for speech to text and recording purpose
setButtonHandlers();
enableButtons(false);
mp = new MediaPlayer();
upload .setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//String rootpath = Environment.getExternalStorageDirectory().getAbsolutePath();
//loadAllAudios(rootpath);
File file = new File("/mnt/sdcard/Download/57FYsUnoWxj2.128.mp3");
String path = file.getAbsolutePath();
new MyAsyncTask().execute(path);
UploadToSoundCloudTask uploadTask = new UploadToSoundCloudTask(this, wrapper);
uploadTask.execute(new AudioClip(path));
}
});
}
private class UploadToSoundCloudTask extends AsyncTask<AudioClip, Integer, Integer> {
private Uploadaudiogallery recordActivity;
private ApiWrapper wrapper;
private String clipName;
public UploadToSoundCloudTask(OnClickListener onClickListener, ApiWrapper wrapper) {
this.recordActivity = (Uploadaudiogallery) onClickListener;
this.wrapper = wrapper;
}
@SuppressLint("NewApi")
protected Integer doInBackground(AudioClip... clips) {
try {
Log.d("DDDDD", "uploading in background...");
File audioFile = new File(clips[0].path);
audioFile.setReadable(true, false);
HttpResponse resp = wrapper.post(Request.to(Endpoints.TRACKS)
.add(Params.Track.TAG_LIST, "demo upload")
.withFile(Params.Track.ASSET_DATA, audioFile));
Log.d("DDDDD", "background thread done...");
return Integer.valueOf(resp.getStatusLine().getStatusCode());
} catch (IOException exp) {
Log.d("DDDDD",
"Error uploading audioclip: IOException: "
+ exp.toString());
return Integer.valueOf(500);
}
}
protected void onProgressUpdate(Integer... progress) {
}
protected void onPostExecute(Integer result) {
Log.d("DDDDD", "UI thread resume: got result...");
if (result.intValue() == HttpStatus.SC_CREATED) {
Toast.makeText(
this.recordActivity,
"upload successful: "
+ ": " + clipName, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(
this.recordActivity,
"Invalid status received: " + result.toString()
+ ": " + clipName, Toast.LENGTH_SHORT).show();
}
}
}
我也使用了Java api-wrapper jar文件。点击上传其节目应用程序已停止

如何将路径和上传音频发送到soundcloud，然后将id发送到我的服务器端..
答案 0 :(得分：3)
替换此
UploadToSoundCloudTask uploadTask = new UploadToSoundCloudTask(this, wrapper); uploadTask.execute(new AudioClip(path));
通过
UploadToSoundCloudTask uploadTask = new UploadToSoundCloudTask(ActivtiyName.this, wrapper); uploadTask.execute(new AudioClip(path));
在您的情况下，this不会引用活动上下文
上传查看此处的示例
Downalod java-wrapper-api.jar并将其添加到libs文件夹
从sdcard获取音频文件的路径
上传
http://developers.soundcloud.com/docs#uploading
从上述链接中引用
要上传声音，请向/ tracks端点发送POST请求
创建一个包装器实例：
ApiWrapper wrapper = new ApiWrapper("client_id", "client_secret", null, null);
获得一个代币：
wrapper.login("username", "password");
向/ tracks端点发出POST请求。在按钮上单击调用AsyncTask
class TheTask extends AsyncTask<Void,Void,Void>
{
@Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try {
wrapper = new ApiWrapper("client_id",
"client_secret",
null,
null);
token = wrapper.login("username", "password");
upload();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
上传方法。
public void upload()
{
try {
Log.d("DDDDD", "uploading in background...");
File audioFile = new File("/mnt/sdcard/Music/A1.mp3");
// replace the hardcoded path with the path of your audio file
audioFile.setReadable(true, false);
HttpResponse resp = wrapper.post(Request.to(Endpoints.TRACKS)
.add(Params.Track.TITLE, "A1.mp3")
.add(Params.Track.TAG_LIST, "demo upload")
.withFile(Params.Track.ASSET_DATA, audioFile));
Log.i("......",""+Integer.valueOf(resp.getStatusLine().getStatusCode()));
Log.d("DDDDD", "background thread done...");
} catch (IOException exp) {
Log.d("DDDDD",
"Error uploading audioclip: IOException: "
+ exp.toString());
}
}
