Android incompeted download file

I try to download audio from a URL. I use following sample download manager code from Github https://github.com/folee/Download_Mgr

My problem is If i cancel download, Incomplete mp3 file still there in SDcard. How can i remove Incomplete mp3 files?

 @Override
    public void onClick(View v) {
        Intent downloadIntent = new Intent(DownloadValues.Actions.DOWNLOAD_SERVICE_ACTION);

        switch (v.getId()) {
        case R.id.btn_continue:
            // mDownloadManager.continueTask(mPosition);
            downloadIntent.putExtra(DownloadValues.TYPE, DownloadValues.Types.CONTINUE);
            downloadIntent.putExtra(DownloadValues.URL, url);
            mContext.startService(downloadIntent);

            mViewHolder.continueButton.setVisibility(View.GONE);
            mViewHolder.pauseButton.setVisibility(View.VISIBLE);
            break;
        case R.id.btn_pause:
            // mDownloadManager.pauseTask(mPosition);
            downloadIntent.putExtra(DownloadValues.TYPE, DownloadValues.Types.PAUSE);
            downloadIntent.putExtra(DownloadValues.URL, url);
            mContext.startService(downloadIntent);

            mViewHolder.continueButton.setVisibility(View.VISIBLE);
            mViewHolder.pauseButton.setVisibility(View.GONE);
            break;
        case R.id.btn_delete:
            // mDownloadManager.deleteTask(mPosition);
            downloadIntent.putExtra(DownloadValues.TYPE, DownloadValues.Types.DELETE);
            downloadIntent.putExtra(DownloadValues.URL, url);
            mContext.startService(downloadIntent);

            removeItem(url);
            break;
        }
    }

my file bath :

 public class ConfigUtils {

 public static void InitPath(Context ctx) {
    File temFile = Environment.getExternalStorageDirectory();

    if (temFile != null && temFile.canWrite() && Util.getAvailableExternalMemorySize() > 0) {
        IMG_PATH = Environment.getExternalStorageDirectory().getPath() + "/DL_Mgr/Image/";
        FILE_PATH = Environment.getExternalStorageDirectory().getPath() + "/DL_Mgr/Downloads/";
    }
    else {
        IMG_PATH = ctx.getFilesDir() + "/Image/";
        FILE_PATH = ctx.getFilesDir() + File.separator;
    }

    new File(IMG_PATH).mkdirs();
    new File(FILE_PATH).mkdirs();
    Log.i(TAG, "IMG_PATH-->" + IMG_PATH + "\n FILEPATH-->" + FILE_PATH);
}

}

I use this code for delete temp files but not work

 case R.id.btn_delete:

            File tempFile = new File(ConfigUtils.FILE_PATH + "filename".toString());
            if(tempFile.exists()) {
                tempFile.delete();
            }

But it not work EDIT: WORKING CODE: (If download mp3 temp file remane like : "sample.mp3.download"

so ichanged code like this it work fine

 File tempFile = new File(ConfigUtils.FILE_PATH + filename +".download".toString());
            if(tempFile.exists()) {
                tempFile.delete();
            }

Solution

Before downloading starts. You must know where you are saving the file. So probably a absolute path or Uri pointing to a file in sdcard that you are giving to Download manager to store your file at.
Incase of cancel. create a file object from that uri or absolute path and call delete on file object if exists. Something like this
```
File tempFile = new File(uri.toString());
if(tempFile.exists()) {
    tempFile.delete();
} 
```

This should be simple. Google it out
