FileNotFoundException: No files supported by provider at content

I have an error whenever I try to take a picture by using camera intent.
This is the error

And this is my paths :

</paths>
And this is my provider in manifest :
<provider
android:name=".data.ProductProvider"
android:authorities="com.example.fahad.inventory"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_provider_paths" />
</provider>
I have seen some posts like this by I don't understands it. or it didn't help me with my problem.
The error in the logs are pointing to :
getContentResolver().openFileDescriptor(uri, "r");
Also the data returned in onActivityResult from the camera is always null.
I think the problem is I have to implement OpenFile method in my custom contentProvider but the problem I don't know what to write in that method.
Or the getUriForFile return wrong uri.
Please help me I'm in this problem for two weeks now and it seems I'm not going anywhere.
And I'm new to contentProvider.
Thanks in Advance And happy coding !

Download PDF not working

In my application, I have an expandablelistview and I want to open a PDF downloaded from the internet when I click on a specific child. The problem is that the pdf file (Read.pdf) is always empty, meaning that the download is not working.
Downloader Class:
public class Downloader {
public static void DownloadFile(String fileURL, File directory) {
try {
FileOutputStream f = new FileOutputStream(directory);
URL u = new URL(fileURL);
HttpURLConnection c = (HttpURLConnection) u.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
InputStream in = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = in.read(buffer)) > 0) {
f.write(buffer, 0, len1);
}
f.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Part of the Activity:
private void registerClick() {
expListView.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
if ((groupPosition == 0) && (childPosition == 0)){
File file = new File(Environment.getExternalStorageDirectory()+File.separator+"IAVE", "Read.pdf");
try {
file.createNewFile();
} catch (IOException e1) {
e1.printStackTrace();
}
Downloader.DownloadFile("https://www.cp.pt/StaticFiles/Passageiros/1_horarios/horarios/PDF/lx/linha_cascais.pdf", file);
AbrirPDF.showPdf();
} else {
}
return false;
}
});
}
I think the OpenPDF (AbrirPDF) doesn't have any problem, but I will post it...
public class AbrirPDF {
public static void showPdf()
{
File file = new File(Environment.getExternalStorageDirectory()+File.separator+"IAVE/Read.pdf");
PackageManager packageManager = ContextGetter.getAppContext().getPackageManager();
Intent testIntent = new Intent(Intent.ACTION_VIEW);
testIntent.setType("application/pdf");
List list = packageManager.queryIntentActivities(testIntent, PackageManager.MATCH_DEFAULT_ONLY);
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
Uri uri = Uri.fromFile(file);
intent.setDataAndType(uri, "application/pdf");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ContextGetter.getAppContext().startActivity(intent);
}
}
Thank you.

Ideally, your download should happen in a separate thread to avoid locking your app.
Here is an example that also includes a progress bar.

case progress_bar_type: // we set this to 0
pDialog = new ProgressDialog(this);
pDialog.setMessage("Downloading file. Please wait...");
pDialog.setIndeterminate(false);
pDialog.setMax(100);
pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

pDialog.show();

}
}

#Override

try {

URLConnection conection = url.openConnection();
conection.connect();
// this will be useful so that you can show a tipical 0-100%
// progress bar
int lenghtOfFile = conection.getContentLength();
// download the file
InputStream input = new BufferedInputStream(url.openStream(),
8192);
// Output stream
OutputStream output = new FileOutputStream(Environment
.getExternalStorageDirectory().toString()
+ "/2011.kml");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress("" + (int) ((total * 100) / lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
} catch (Exception e) {
Log.e("Error: ", e.getMessage());
}
return null;
}
protected void onProgressUpdate(String... progress) {
// setting progress percentage
pDialog.setProgress(Integer.parseInt(progress[0]));
}
#Override

Image not uploading to server and database

App says Image Downloaded Successfully but no image shows up in gallery

The app gets the image from the given URL and displays the image and on clicking the download button, it says that the image has been downloaded successfully but there is no image in the gallery. Can someone tell me how I can fix this?
This is my Image View and Download activity. I have also added proper permissions to the Android Manifest.

try this,
After saving the Image you have to use this
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(file);
mediaScanIntent.setData(contentUri);
getApplicationContext().sendBroadcast(mediaScanIntent);
you have to send a broadcast to System ,changes to reflect in the Gallery , so that you image will be shown in the gallery , if not , you have to restart Device for check the downloaded images..
hope it helps you..

I think you have to use Aquery for image download it is very Useful for image download from net.
Here the link for Aquery
