所以我在这里使用下载器进行for循环：
**更新了代码 - 在这里你得到PostExecute＆amp;状态栏更新的进度
ArrayMap<String, String> urls = new ArrayMap<String, String>();
urls.put(urlone, "first.xml");
urls.put(urltwo, "second.xml");
urls.put(urlthree+"?anid=" + androidId,"score.xml");
for (int i =0; i < urls.size(); i ++) {
Log.e("Position i=",String.valueOf(i));
Log.e("urls size",String.valueOf(urls.size()));
String urlStr = urls.keyAt(i);
Log.e("current URL keyAt",urls.keyAt(i));
OutputStream file = openFileOutput(urls.valueAt(i),Context.MODE_PRIVATE);
Log.e("file written valueAt",urls.valueAt(i));
float fPercent = (((float)(i-1))/urls.size())*100.0f;
Log.e("URL url site", String.valueOf(urls.size()));
URL url = new URL(urlStr);
URLConnection ucon = url.openConnection();
int lengthOfFile = ucon.getContentLength();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
//Log.d("SPLASH LOGGER", "Got InputStream and BufferedInputStream");
BufferedOutputStream bos = new BufferedOutputStream(file);
//Log.d("SPLASH LOGGER", "Got FileOutputStream and BufferedOutputStream");
byte data[] = new byte[1024];
long total = 0;
int count;
//loop and read the current chunk
while ((count = bis.read(data)) != -1) {
//keep track of size for progress.
total += count;
publishProgress(fPercent + (((float)total)/lengthOfFile)*(100.0f - fPercent));
bos.write(data, 0, count);
}
//Have to call flush or the file can get corrupted.
bos.flush();
bos.close();
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
@Override
protected void onProgressUpdate(Float... values) {
TextView splashstatus = (TextView) findViewById(R.id.spstatus);
if (values[0]>0)
{
splashstatus.setText(String.valueOf(values[0]));
}
//Log.i("String.valueOf values", String.valueOf(values[0]));
}
@Override
protected void onPostExecute(Void result) {
TextView splashstatus = (TextView) findViewById(R.id.spstatus);
splashstatus.setText("DONE...");
splashTread.start();
}
@Override
protected void onPreExecute()
{TextView splashstatus = (TextView) findViewById(R.id.spstatus);
splashstatus.setText("UPDATING DATA");
}
}
所以我的问题如下：当我在Android 7.0（Api 27）上启动此程序时，一切正常，但在Android 6.x（API 23）上下载，下载器仅下载urltwo和urlthree - first.xml不在手机上，而相同的代码在更高版本的android上完美运行。 我没有想法解决这个问题，是否有可能为api 23 ..我必须从i = 1开始？

关注这个Logcat，我没有改变顺序，当我复制＆amp;糊。它会让人感到困惑，但它确实有效。
