I am getting a URL in response. I want to download the html of that URL so that user can see it offline also. Its a recyclerView in which each items contain a URL. So when user clicks on the URL of one item it should save it in external disk.
Below is the code:
NewsAdapter:

Gson gson = new GsonBuilder()
.setLenient()
.create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://www.nytimes.com/")

ApiInterface retrofitInterface = retrofit.create(ApiInterface.class);
final Call< ResponseBody > call = retrofitInterface.downloadFileWithDynamicUrlSync("2017/09/13/us/nursing-home-deaths-florida.html");
Log.i("Retrofit req execute", "initiated");
new AsyncTask<Void, Void, Void>() {
#Override

boolean writtenToDisk = false;
try {
writtenToDisk = writeResponseBodyToDisk(call.execute().body());
} catch (IOException e) {
e.printStackTrace();
}
;
Log.d("success", "file download was a success? " + writtenToDisk);
return null;
}
}.execute();
break;
private boolean writeResponseBodyToDisk(ResponseBody body) {
try {
// todo change the file location/name according to your needs
File futureStudioIconFile = new File(Environment.DIRECTORY_DOWNLOADS + File.separator + "Future Studio Icon.png");
InputStream inputStream = null;
OutputStream outputStream = null;
try {
byte[] fileReader = new byte[4096];
long fileSize = body.contentLength();
long fileSizeDownloaded = 0;
inputStream = body.byteStream();
outputStream = new FileOutputStream(futureStudioIconFile);
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
outputStream.write(fileReader, 0, read);
fileSizeDownloaded += read;
Log.d("filedownload", "file download: " + fileSizeDownloaded + " of " + fileSize);
}
outputStream.flush();
return true;
} catch (IOException e) {

}
} catch (IOException e) {

}
}
ApiInterface:
// option 2: using a dynamic URL
#Streaming
#GET
Call<ResponseBody> downloadFileWithDynamicUrlSync(#Url String fileUrl);
I am also getting the error:
Failed to invoke public com.squareup.okhttp.ResponseBody() with no args
Can someone tell me how to implement it correctly.
Use URL with domain name to download file.Remove streaming annotation don't need that.
You are not receiving file body as you are not using complete URL.
Create an interface like this
#GET
Call<ResponseBody> downloadFile(#Url String url);
Then use this code :
public void onResponse(Call<ResponseBody> call, Response<ResponseBody>
response)
{
if (response.isSuccessful()) {
String filePath = Utils.downloadFile(response.body(),"filename");
}
}
public String downloadFile(ResponseBody body, String fileName) {
String filePath = null;
try {
int count;
byte data[] = new byte[1024 * 4];
InputStream bis = new BufferedInputStream(body.byteStream(), 1024 * 8);
File storageDir = new File(Environment.getExternalStorageDirectory(), "AppName");
if (!storageDir.exists()) {
storageDir.mkdirs();
}
File outputFile = new File(storageDir, fileName);
OutputStream output = new FileOutputStream(outputFile);
while ((count = bis.read(data)) != -1) {
output.write(data, 0, count);
}
output.flush();
output.close();
bis.close();
filePath = outputFile.getAbsolutePath();
} catch (Exception e) {
e.printStackTrace();
}
return filePath;
}

I am using OkHttp to download a file from the server.
And this is my code:
I set read and write timeout for it:
public static final String API_BASE_URL = "http://XXXX:8080/tablet/";
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder()
.connectTimeout(60,TimeUnit.SECONDS)
.writeTimeout(60,TimeUnit.SECONDS);
This is my createServiceFile:
public static <S> S createServiceFile(Class<S> serviceClass, final String token) {
if (token != null) {
httpClient.addInterceptor(new Interceptor() {
#Override
public Response intercept(Chain chain) throws IOException {
Request original = chain.request();
Request.Builder requestBuilder = original.newBuilder()
.header("Authorization", token)
.header("Accept", "text/html,application/xhtml+xml,application/pdf,application/xml;q=0.9," +
"image/webp,audio/mpeg ,image/png,audio/mp4,image/jpeg,*/*;q=0.8")
.method(original.method(), original.body());
Request request = requestBuilder.build();
return chain.proceed(request);
}
});
}
OkHttpClient client = httpClient.build();
Retrofit retrofit = builder.client(client).build();
return retrofit.create(serviceClass);
}
And this is my code that I write the response to SD Card (in response contentLength is -1 because the server doesn't send it to me):
public DownloadRequest DownloadFile() {
//Creating folder for Application in SD Card if it's not created yet in App Class!
new java.io.File(G.DIR_APP).mkdirs();
new java.io.File(G.DIR_MEDIA).mkdirs();
APIService downloadService = ServiceGenerator.createServiceFile(APIService.class, G.TOKEN);
downloadService.downloadFileWithDynamicUrlSync(url)//set URL of the file
.subscribeOn(Schedulers.newThread())
.observeOn(Schedulers.io())
.delay(30, TimeUnit.MILLISECONDS)
.subscribe(new Observer<ResponseBody>() {
#Override
public void onSubscribe(Disposable d) {
}
#Override
public void onNext(ResponseBody responseBody) {
Log.i(TAG, "On Next And Current App is: " + fileName);
if (writeResponseBodyToDisk(responseBody)) {
Log.i(TAG, fileName + "Downloaded successful");
//This Download was successful Then try to set downloadResult true
result = true;
} else {
result = false;
}
}
#Override
public void onError(Throwable e) {
Log.i(TAG, "!!!!!!!!!!!!!!!!\n\nOn Error And Current App is: " +
fileName + " And Error is" + e.toString() + "\n\n!!!!!!!!!!!!!!!!\n\n");
//Set downloadResult false
result = false;
if (listener != null) {
listener.onDownloadCompleteListener(false);
}
}
#Override
public void onComplete() {
Log.i(TAG, "On Complete And Current App is: " + fileName);
if (listener != null) {
if (result) {
listener.onDownloadCompleteListener(true);
} else {
listener.onDownloadCompleteListener(false);
}
}
}
});
return this;
}
And this code will write response to disck:
private boolean writeResponseBodyToDisk(ResponseBody body) {
// Location to save downloaded file and filename
java.io.File file = new java.io.File(destinationPath + fileName + "." + extension);
try {
InputStream inputStream = null;
OutputStream outputStream = null;
int bytesBuffered = 0;
try {
byte[] fileReader = new byte[bufferSize];
downloadSize = 0;
inputStream = body.byteStream();
/*
* If append requested we have to append new bytes to
* Exists bytes on the storage
*/
if (appendNeed) {
outputStream = new FileOutputStream(file, true);
} else {
outputStream = new FileOutputStream(file);
}
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
bytesBuffered += read;
if (bytesBuffered > 1024 * 1024) {
// outputStream.write(fileReader, 0, read);
outputStream.flush();
bytesBuffered = 0;
}
outputStream.write(fileReader, 0, read);
downloadSize += read;
percent = (int) (100.0f * (float) downloadSize / totalSize);
if (listener != null) {
listener.onDownloadPercentListener(percent);
}
}
outputStream.flush();
inputStream.close();
outputStream.close();
return true;
} catch (IOException e) {
Log.i(TAG, "Error in download" + e.toString());
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
Log.i(TAG, "Error in download" + e.toString());
return false;
}
}
But I get false from this method (writeResponseBodyToDisk)with error of
java.net.SocketTimeoutException while the file is downloaded correctly!
I think this problem it about contentLength that is -1 for me.
Thank you for your answers.
I am using a service in my app that I used to retrofit to download some "apk" files in the background.
I want to check downloaded file size with received file size to make sure I get "apk" completely.
but when i use response.body().contentLength() it is -1!
This is my code:
private void downloadAppFromServer(String url, final String fileId) {
APIService downloadService = ServiceGenerator.createServiceFile(APIService.class, "181412655", "181412655");
Call<ResponseBody> call = downloadService.downloadFileWithDynamicUrlSync(url);
call.enqueue(new Callback<ResponseBody>() {
#Override
public void onResponse(Call<ResponseBody> call, final Response<ResponseBody> response) {
if (response.isSuccess()) {
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... voids) {
Log.d("LOGO", "server contacted and has file");
Log.d("LOGO", "FILE SIZE: " + response.body().contentLength());
boolean writtenToDisk = writeResponseBodyToDisk(response.body(), fileId);
Log.d("LOGO", "file download was a success? " + writtenToDisk);
return null;
}
}.execute();
}
}
#Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
});
}
And this is my writeToDisk Method:
private boolean writeResponseBodyToDisk(ResponseBody body, String fileId) {
try {
// Location to save downloaded file and filename
File DownloadFile = new File(G.DIR_APK + "/" + fileId + ".apk");
InputStream inputStream = null;
OutputStream outputStream = null;
try {
byte[] fileReader = new byte[4096];
long fileSize = body.contentLength();
long fileSizeDownloaded = 0;
inputStream = body.byteStream();
Log.d("LOGO", "file size is: " + fileSize ); //This is -1 !
outputStream = new FileOutputStream(DownloadFile);
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
outputStream.write(fileReader, 0, read);
fileSizeDownloaded += read;
}
outputStream.flush();
if (fileSize == fileSizeDownloaded) {
return true;
} else {
return false;
}
} catch (IOException e) {
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
return false;
}
}
-1 means that web server doesnt give you any information about length of file.
Retrofit gets header content-length. If it doesnt exist response.body().contentLength() returns -1.
Try to make HEAD HTTP request to the same URL, it might return the Content-Length.
I try to download file from server and save it in internel storage and then install it.
I downloaded it using retrofit by this code
Call<ResponseBody> call = apiService.getNewVersion();
call.enqueue(new Callback<ResponseBody>() {
#Override
public void onResponse(Call<ResponseBody> call,
Response<ResponseBody> response) {
if (response.isSuccessful() ) {
Log.d("1", "server contacted and has file");
boolean writtenToDisk =
writeResponseBodyToDisk(response.body());
Log.d("2", "file download was a success? " + writtenToDisk);
} else {
Log.d("3", "server contact failed");
}
}
#Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.e("4", "error");
}
});
and I saved it by this code
private boolean writeResponseBodyToDisk(ResponseBody body) {
try {
// todo change the file location/name according to your needs
File futureStudioIconFile = new
File(context.getExternalFilesDir(null) + File.separator + "app-debug.apk");
InputStream inputStream = null;
OutputStream outputStream = null;
try {
byte[] fileReader = new byte[4096];
long fileSize = body.contentLength();
long fileSizeDownloaded = 0;
inputStream = body.byteStream();
outputStream = new FileOutputStream(futureStudioIconFile);
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
outputStream.write(fileReader, 0, read);
fileSizeDownloaded += read;
Log.d("TAG", "file download: " + fileSizeDownloaded + " of "
+ fileSize);
}
outputStream.flush();
return true;
} catch (IOException e) {
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
return false;
}
}
its original 4.56MB but it shows 6.08MB in Android storage.
When I open it to install it shows
version N /A size N/ A
and when I try to install it, it shows this parse problem
Do you have any idea to solve this problem?
How to remove extra bytes?
You should make sure that you use HttpResponseMessage.content in your web service method because a normal return will not be a standard size for the file that you want:
[HttpGet]
[Route("api/Depository/DownloadFileFTP")] // /{pass}
public HttpResponseMessage DownloadFileFTP() //string pass
{
HttpResponseMessage result = null;
string ftphost = "*******";
string ftpfilepath = "/app-debug.apk";
byte[] fileData;
string ftpfullpath = "ftp://" + ftphost + ftpfilepath;
using (WebClient request = new WebClient())
{
request.Credentials = new NetworkCredential("**", "****");
fileData = request.DownloadData(ftpfullpath);
}
byte[] bytes = fileData;
result = Request.CreateResponse(HttpStatusCode.OK);
result.Content = new ByteArrayContent(bytes);
result.Content.Headers.ContentDisposition = new
System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
result.Content.Headers.ContentDisposition.FileName = "app.apk";
return result;
}
I need to download image from server and save it to folder, so I am using Retrofit 2.
Problem is that saved images is empty when I look for it in folder and I tried to debug and saw that Bitmap is null.
I do not get why, here is my code:
#GET("images/{userId}/{imageName}")
#Streaming
Call<ResponseBody> downloadImage(#Path("userId") String userId, #Path("imageName") String imageName);
Download image code:
private void downloadImage(final int position) {
String url = "htttp://myserver.com/";
retrofitImage = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
imageApi = retrofitImage.create(BlastApiService.class);
String userId = feedList.get(position).getUserId();
String fileName = feedList.get(position).getFile();
Call<ResponseBody> imageCall = imageApi.downloadImage(userId, fileName );
imageCall.enqueue(new Callback<ResponseBody>() {
#Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
if(response.isSuccess()){
String fileName = feedList.get(position).getFile();
InputStream is = response.body().byteStream();
Bitmap bitmap = BitmapFactory.decodeStream(is);
saveImage1(bitmap, fileName);
} else{
try {
Log.d("TAG", "response error: "+response.errorBody().string().toString());
} catch (IOException e) {
e.printStackTrace();
}
}
}
#Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.d("TAG", "Image download error: " + t.getLocalizedMessage());
}
});
}
Here is method to save image.
private void saveImage1(Bitmap imageToSave, String fileName) {
// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + "/FOLDER_NAME/");
// create this directory if not already created
dir.mkdir();
// create the file in which we will write the contents
File file = new File(dir, fileName);
try {
FileOutputStream out = new FileOutputStream(file);
imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
counter++;
// if (counter < feedList.size()) {
//downloadImage(counter);
//} else {
setImage();
//}
} catch (Exception e) {
e.printStackTrace();
}
}
This worked for me:
public static boolean writeResponseBody(ResponseBody body, String path) {
try {
File file = new File(path);
InputStream inputStream = null;
OutputStream outputStream = null;
try {
byte[] fileReader = new byte[4096];
//long fileSize = body.contentLength();
//long fileSizeDownloaded = 0;
inputStream = body.byteStream();
outputStream = new FileOutputStream(file);
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
outputStream.write(fileReader, 0, read);
//fileSizeDownloaded += read;
}
outputStream.flush();
return true;
} catch (IOException e) {
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
return false;
}
}
after call this method you can get image from path:
boolean result = writeResponseBody(body, path);
if(result) {
Bitmap bitmap = BitmapFactory.decodeFile(path)
}
private boolean writeResponseBodyToDisk(ResponseBody body, String name) {
try {
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString() + "/MyApp";
File dir = new File(path);
if (!dir.exists())
dir.mkdirs();
File futureStudioIconFile = new File(path, name + ".pdf");//am saving pdf file
if (futureStudioIconFile.exists())
futureStudioIconFile.delete();
futureStudioIconFile.createNewFile();
InputStream inputStream = null;
OutputStream outputStream = null;
try {
byte[] fileReader = new byte[4096];
long fileSize = body.contentLength();
long fileSizeDownloaded = 0;
inputStream = body.byteStream();
outputStream = new FileOutputStream(futureStudioIconFile);
while (true) {
int read = inputStream.read(fileReader);
if (read == -1) {
break;
}
outputStream.write(fileReader, 0, read);
fileSizeDownloaded += read;
}
outputStream.flush();
return true;
} catch (IOException e) {
e.printStackTrace();
return false;
} finally {
if (inputStream != null) {
inputStream.close();
}
if (outputStream != null) {
outputStream.close();
}
}
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
I am downloading some pics using OkHttp lib, everything is ok but all of them appears in recent files. Is there a way to disable my pics to be there.
My code is:
public static void downloadSimpleFile(String urlLink, String myPath, String fileName) {
OutputStream outputStream = new FileOutputStream(new File(myPath + fileName));
byte[] bytes = new byte[1024];
int read;
final OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(5, TimeUnit.SECONDS);
client.setReadTimeout(5, TimeUnit.SECONDS);
client.setWriteTimeout(5, TimeUnit.SECONDS);
Request request = new Request.Builder()
.url(urlLink)
.build();
try {
Response response = client.newCall(request).execute();
if (response != null) {
InputStream inputStream = response.body().byteStream();
if (inputStream != null) {
while ((read = inputStream.read(bytes)) != -1) {
outputStream.write(bytes, 0, read);
}
}
}
} catch (IOException e) {
//exception code treatement
}
}
EDIT:
like #Knossos mentioned in comments, I create this .nomedia file, but my pics still appearing, used code:
public static void createNoMediaFile() {
File file = new File(mypath + ".nomedia");
if (!file.exists()) {
try {
if (file.createNewFile()) {
//is created
}
} catch (IOException e) {
//exception
}
}
}
