使用开源项目xutils实现多线程断点下载

HttpUtils http = new HttpUtils();
http.download(path, "/mnt/sdcard/xxx.exe", true, new RequestCallBack<File>() {

@Override
public void onSuccess(ResponseInfo<File> arg0) {
Toast.makeText(MainActivity.this, "下载成功", 0).show();
}

@Override
public void onLoading(long total, long current, boolean isUploading) {
//ProgressBar进度条更新
pb0.setMax((int) total);
pb0.setProgress((int) current);
super.onLoading(total, current, isUploading);
}

@Override
public void onFailure(HttpException arg0, String arg1) {
Toast.makeText(MainActivity.this, "下载失败"+arg1, 0).show();
}
});
