我按照改装页面上的说明下载了一个图像,但是,如果没有@streaming标记,inputstream.read(buffer)将立即等于-1,从而导致文件为空(图像非常小,只有几百kb)即使我使用@streaming标记,当我使用inputstream时,由于illegalstateexception,应用程序也会不断崩溃
我尝试了httpconnection,可以很好地下载图像。不过,我真的很想让它与改造工作
public static String downloadImage(String bearer, long pictureId,Context context){
String path = "";
NetworkAPI apiService = NetworkClient.getClient().create(NetworkAPI.class);
//Call<ResponseBody> downloadCall = apiService.downloadImage(bearer,pictureId);
Call<ResponseBody> downloadCall = apiService.downloadFileWithDynamicUrlSync("https://androidtutorialpoint.com/api/RetrofitAndroidImageResponse");
try {
Response<ResponseBody> response = downloadCall.execute();
if(response.isSuccessful()) {
Log.d(TAG, "success download" + response.body().string());
Log.d("DownloadImage", "Reading and writing file");
InputStream in = null;
OutputStream out = null;
try {
in = response.body().byteStream();
File file = PictureUtil.createImageFile(context);
Uri photoURI = FileProvider.getUriForFile(context,
"vn.com.wk.bradleyaudit.fileprovider",
file);
out = new FileOutputStream(file);
long fileSize = response.body().contentLength();
long downloadedSize = 0;
Log.d("DownloadImage", "size"+fileSize);
byte[] buffer = new byte[4096];
while (true) {
int bufferLength = in.read(buffer);
Log.d("DownloadImage", "buffer Length"+bufferLength);
if (bufferLength == -1) {
break;
}
out.write(bufferLength);
out.write(buffer, 0, bufferLength);
downloadedSize += bufferLength;
}
out.flush();
path = photoURI.toString();
Log.d("DownloadImage", "path"+path);
}
catch (IOException e) {
Log.d("DownloadImage",e.toString());
}
finally {
if (in != null) {
in.close();
}
if (out != null) {
out.close();
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
return path;
}

试试这个,
还增加了依赖性;
