this code keeps coming out with the FileNotFoundException, but the file is there, if you follow the url you can see it.
does it have to be hosted in a specific way? or is it something wrong with the way im getting it
EDIT: this is the logcat message

When I do http request in the PoolData(), request returns with data, and in AccoutData is always null.
In debugger, if I wait 1-2 sec after PoolData(), next request - returns not null. Method oder doesn't metter. Why is that, and how can I wait for 2nd request?

I had the same issue, however not on my device but on one of my customers. I found someting on this site. They use the following code:
Image image;
try {
image = mImageReader.acquireLatestImage();
} catch (RuntimeException e) {
/* In API level 23 or below, it will throw "java.lang.RuntimeException:
ImageReaderContext is not initialized" when ImageReader is closed. To make the
behavior consistent as newer API levels, we make it return null Image instead.*/
if (isImageReaderContextNotInitializedException(e)) {
image = null;
} else {
throw e; // only catch RuntimeException:ImageReaderContext is not initialized
}
}
if (image == null) {
return null;
}
private boolean isImageReaderContextNotInitializedException(RuntimeException e) {
return "ImageReaderContext is not initialized".equals(e.getMessage());
}
I don't know yet, if it solves the issue, because the crash does not occur on my device. Let me know if it helps.

I am using wifi direct to send file between two android phones.
sender code:

InputStream inputStream = null;
try {
outputStream = socket.getOutputStream();
inputStream = new FileInputStream(exportTempFile);
byte[] buf = new byte[socket.getSendBufferSize()];
int len = 0;
while ((len = inputStream.read(buf)) != -1) {

}
outputStream.flush();
return 0;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (socket != null) {
if (socket.isConnected()) {
try {
if (outputStream != null) {
outputStream.close();
}
if (inputStream != null) {
inputStream.close();
}
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
receiver code:
OutputStream outputStream = null;
InputStream inputStream = null;
try {
tempDir = new File(context.getCacheDir(), "temp");
if (!tempDir.exists()) {
tempDir.mkdir();
}
File file = new File(tempDir, "temp.zip");
file.createNewFile();
outputStream = new FileOutputStream(file);
inputStream = socket.getInputStream();
byte[] buf = new byte[socket.getReceiveBufferSize()];
int len = 0;
while ((len = inputStream.read(buf)) != -1) {
outputStream.write(buf, 0, len);
outputStream.flush();
}
return file;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (socket != null) {

outputStream.close();
}
if (inputStream != null) {
inputStream.close();
}
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
However, I always get "W/System.err" at the receiver side when running bytestream.copy . I wonder if I did something wrong. Did I close socket too early so the other side can not get data?
error is as below:

ok so im trying capture the webview on button click, of the web page that is being displayed on my webview activity and save it to the sd card.
i have in my manifest the right permission to write external storage and all webview features are working just great, just when i attempt to capture the image.
public void onClick(View v) {
switch(v.getId()) {
case R.id.button1:
WebViewClientDemoActivity.web.goBack();
break;
case R.id.button2:
WebViewClientDemoActivity.web.goForward();
break;
case R.id.button3:
WebViewClientDemoActivity.web.capturePicture();
//Capture Picture
Picture picture = WebViewClientDemoActivity.web.capturePicture();
//Create a new canvas
Canvas mCanvas = new Canvas();
//Draw the Picture into the Canvas
picture.draw(mCanvas);
//Create a Bitmap
Bitmap sreenshot = Bitmap.createBitmap(picture.getWidth(),
picture.getHeight(),Config.ARGB_8888);
//copy the content fron Canvas to Bitmap
//mCanvas.drawBitmap(mBitmapScreenshot, 0, 0, null);
mCanvas.drawBitmap(sreenshot, 0, 0, null);
//Save the Bitmap to local filesystem
if(sreenshot != null) {
ByteArrayOutputStream mByteArrayOpStream = new
ByteArrayOutputStream();
sreenshot.compress(Bitmap.CompressFormat.JPEG, 90,
mByteArrayOpStream);
try {
File folder = new File(Environment.getExternalStorageDirectory().toString()+"/Enlighten/Images");
folder.mkdirs();
// create a File object for the parent directory
File outputFile = new File(folder, "enlighten.jpg");
// now attach the OutputStream to the file object, instead of a String representation
FileOutputStream fos = new FileOutputStream(outputFile);
fos.write(mByteArrayOpStream.toByteArray());
fos.close();
Toast.makeText(WebViewClientDemoActivity.this, "File Created", Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(WebViewClientDemoActivity.this, "File Not Found", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
Im getting this error message. (UPDATED)

The openFileOutput() expects just the file name, without path separators, because it assumes that the file will be created in the app's private data area (if my memory doesn't cheat me then it should be /data/data/[your app package name]/files/).
To create a file on sdcard you can use FileOutputStream directly, see here for an example.
And another advice is that don't use hardcoded path like /mnt/sdcard because the absolute path of sdcard may vary on different devices, instead you should use Environment.getExternalStorageDirectory()
I resolved my issue with this code so it screen captures from inside the menu
public boolean onOptionsItemSelected (MenuItem item){
// Called when you tap a menu item
switch (item.getItemId()){
case R.id.settings_capture:
item.setIcon(R.drawable.capture);
//Resize the webview to the height of the webpage
int pageHeight = web.getContentHeight();
LayoutParams browserParams = web.getLayoutParams();
web.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, pageHeight));
//Capture the webview as a bitmap
web.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(web.getDrawingCache());
web.setDrawingCacheEnabled(false);
//Create the filename to use
String randomFilenamepart = String.valueOf(new SecureRandom().nextInt(1000000));
String filename = Environment.getExternalStorageDirectory().toString() + "/Enlighten_Mobile_" + randomFilenamepart + ".jpg";
File imageFile = new File(filename);
//Stream the file out to external storage as a JPEG
OutputStream fout = null;
try {
fout = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fout);
fout.flush();
fout.close();
Toast.makeText(WebViewClientDemoActivity.this, "Screen Capture Saved!\n\nImage Saved at location : /sdcard\n\nSaved As: Enlighten_Mobile_xxxxx.jpg", Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(WebViewClientDemoActivity.this, "Problem with Capturing Image or Location to Store Image", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
} finally {
web.setLayoutParams(browserParams);
}
return true;
