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

I hope you can fix my problem:
I have got a textureview to takes photos but when he capture photos, the file who need to contain the picture is empty. I don't know where and what is the problem. I just think that the problem is when the file is created. Thank you to help me.

int width = 640;
int height = 480;
if(jpegSizes!=null && jpegSizes.length>0){
width = jpegSizes[0].getWidth();
height = jpegSizes[0].getHeight();
}
ImageReader reader = ImageReader.newInstance(width,height, ImageFormat.JPEG, 1);

outputSurface.add(reader.getSurface());
outputSurface.add(new Surface(textureView.getSurfaceTexture()));

Try with below code:
File myDir;
String fname;
String id = "123456";
int count = 0;
String root = Environment.getExternalStorageDirectory().toString();
myDir = new File(root + "/PhotoApp/" + id);
myDir.mkdirs();
count++;
counter.setText(String.valueOf(count));
fname = "" + id + "-" + count + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
This code will create a folder PhotoApp and inside the folder, all the images will store.
You can get full code with the camera in my GitHub:

Hello before someone says that i shouldnt store in database as blob, well i need it i have my reasons. Last time i asked this only response i got was like dont store in database or something. Well here is my code thatone part works the other part doesnt works, the part that works is taking photo and displaying it in imageview , not working is uploading to mysql database. If more information is needed tell me i will edit answer. thank you in advance.

I am stuck at this. MY application clicks multiple images programmatically.
Issue is my take picture call is inside button listener click function.
1. When i do button click it triggers the thread for take picture that works.
2. If i directly call that obj.run() it does not-> shows take picture failed at run time.
3. If i do btn.perform click - still fails.
I am building an application that listens on a socket and on a trigger click multiple images n save them to create .gif.

ok the answer is from button click it comes from UI thread. But the function call does not. to run this call the function from UI thread . It will work!!
at com.example.newpingziyi.stir.CheckSdcard$LoadImagesFromSDCard.doInBackground(CheckSdcard.java:316)
error lines was make Stronger!
First.show that's error like java.lang.OutOfMemoryError!
this's code...
class LoadImagesFromSDCard extends AsyncTask<Object, LoadedImage, Object> {
#Override
protected Object doInBackground(Object... params) {
Bitmap newBitmap = null;
File file = new File(localPath);
String[] filepath = file.list();
for (String str : filepath) {
String filename = str;
String imagePath = localPath + "/" + filename;
File files = new File(imagePath);
FileInputStream is = null;
BufferedInputStream bis = null;
try {
is = new FileInputStream(new File(imagePath));
bis = new BufferedInputStream(is);
//this line was wrong!
Bitmap bitmap = BitmapFactory.decodeStream(bis);//this lines was wrong!!
is.close();
bis.close();
if (bitmap != null) {
newBitmap = Bitmap.createScaledBitmap(bitmap, 70, 70,
true);
bitmap.recycle();
if (newBitmap != null) {
publishProgress(new LoadedImage(newBitmap));
}
}
} catch (IOException e) {
}
}
return null;
}
#Override
public void onProgressUpdate(LoadedImage... value) {
addImage(value);
}
#Override
protected void onPostExecute(Object result) {
imageAdapter.notifyDataSetChanged();
}
}
Bitmap bitmap = BitmapFactory.decodeStream(bis);//this lines was wrong!!
now i make change below code.still OutOfMemoryError yet!
class LoadImagesFromSDCard extends AsyncTask<Object, LoadedImage, Object> {

Here is my working code for downloading Bitmap, maybe it will help :

url = url.substring(0, url.indexOf("\""));
final DefaultHttpClient client = new DefaultHttpClient();
final HttpGet getRequest = new HttpGet(url);
try {
HttpResponse response = client.execute(getRequest);
//check 200 OK for success
final int statusCode = response.getStatusLine().getStatusCode();
if (statusCode != HttpStatus.SC_OK) {
Log.w("ImageDownloader", "Error " + statusCode +
" while retrieving bitmap from " + url);
return null;
}
final HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream inputStream = null;
try {
// getting contents from the stream
inputStream = entity.getContent();
// decoding stream data back into image Bitmap that android understands
final Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
return bitmap;
} finally {
if (inputStream != null) {
inputStream.close();
}
entity.consumeContent();
}
}
} catch (Exception e) {
// You Could provide a more explicit error message for IOException
getRequest.abort();
Log.e("ImageDownloader", "Something went wrong while" +
" retrieving bitmap from " + url + e.toString());
}
return null;
