我下载了一张图片供以后离线使用
文件路径：/storage/emulated/0/3a3d95e7b3e84cfb795e4a31bbdf98d1.jpg
我将此异常传递给毕加索时：
java.io.IOException: Invalid marker: ef

....
即使我尝试加载png文件（没有exif），也会发生此异常。我用来存储图像的方法：
public static String okDownloadToFileSync(final String link, final String fileName, final boolean temp, DownloadStatusManager statusManager, ErrorDisplayerInterface errorDisplayerInterface) {
Request request = new Request.Builder()
.url(link)
.build();
if (statusManager != null) {
statusManager.add(Hash.md5(link));
}
OkHttpClient client = Api.getInstance().getOkHttpClient();
OutputStream output = null;
InputStream input = null;
String fileFullName = null;
try {
Response response = client.newCall(request).execute();
final String contentType = response.header("Content-Type");
final String ext = contentTypeMap.get(contentType);
Log.i(TAG, link + "\n --> contentType = " + contentType + "\n --> ext = " + ext);
if (ext == null) {
Log.e(TAG, "-----------\next is null, seems like there is a problem with that url : \n " + link + "\n----------");
return null;
} else if (ext.equals("json")) {
Log.e(TAG, "-----------\ndownloadable file seems to be a json, seems like there is a problem with that url : \n " + link + "\n----------");
return null;
}
//Check if file already exists
if (!temp && fileName != null) {
File test = new File(STORAGE_PATH + fileName + "." + ext);
if (test.exists()) {
Log.i(TAG, "File exists ! : " + test.getPath());
return STORAGE_PATH + fileName + "." + ext;
}
}
// expect HTTP 200 OK, so we don't mistakenly save error report
// instead of the file
if (!response.isSuccessful()) {
Log.e(TAG, "dwnToFileSync bug : connection.getResponseCode() != HttpURLConnection.HTTP_OK");
return null;
}
ResponseBody responseBody = response.body();
if (statusManager != null) {
statusManager.add(Hash.md5(link), responseBody.contentLength());
}
input = responseBody.byteStream();
if (temp) {
//If there is a pb with pdf, add '.pdf' as suffix
File file = File.createTempFile(UUID.randomUUID().toString(), ext, M360Application.getContext().getCacheDir());
fileFullName = file.getPath();
output = new FileOutputStream(file);
} else {
File file = new File(STORAGE_PATH + fileName + "." + ext);
fileFullName = file.getPath();
Log.i(TAG, "File full name : " + fileFullName);
output = new FileOutputStream(file);
}
Log.i(TAG, fileFullName);
byte data[] = new byte[4096];
long total = 0;
int count;
while ((count = input.read(data)) != -1) {
output.write(data, 0, count);
total++;
}
return fileFullName;
} catch (IOException e) {
e.printStackTrace();
errorDisplayerInterface.popError(null, e);
} finally {
if (statusManager != null) {
statusManager.finish(Hash.md5(link));
}
try {
if (output != null)
output.close();
if (input != null)
input.close();
} catch (IOException ignored) {
ignored.printStackTrace();
}
}
return null;
}
请注意，此方法还用于下载各自播放器正确读取的所有类型的文件。
你知道这个＆＃34; ef＆＃34;可能来自？
如果我尝试使用iv.setImageBitmap(BitmapFactory.decodeFile(file.getPath()));，我就会收到此消息：
skia: --- SkImageDecoder::Factory returned null
我试着滑行，看看我是否有更清晰的错误信息：
