I am developing an android app in which i want to save images on server(free server 000webhost).To do this i am encoding my image into string using base64. And sending this string with the POST method using volley.
But the image is not generating on the server side. Can anyone tell me what's wrong?
upload.php
<?php
$servername = "localhost";
$database = "id8258200_image";
$username = "id8258200_qmine1";
$password = "";
$conn = mysqli_connect($servername, $username, $password, $database);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
if(isset($_POST["image"])){
$encoded_string = $_POST["image"];
$image_name="img";
$decoded_string = base64_decode($encoded_string);
$path = "image/$image_name.jpeg";
$file = fopen($path, 'wb');
$is_written = fwrite($file, $decoded_string);
fclose($file);
echo "success";
}
else {
echo "error";
}
?>

Code looks fine to me. Seems like a permission issue. Add these lines to top of your PHP script.
<?php
ini_set('display_errors', 1); // telling PHP to explicitly print all errors
error_reporting(E_ALL); // Show all notices, warnings and fatal errors
Second thing to check if the folder is having enough permission to write a file. Give write permission if not there and see if the code works.
Hope this helps. Happy coding!

I cannot get my imageview uploaded from gallery to stay once the application closes. I already looked at other questions like this one but it is not working for me. I tried shared pref but it is not working. I might be doing it wrong. Could someone look at my code? I want the imageview uploaded from gallery to stay in the imageview even after the application is closed. I want it to only changed when a new picture is uploaded from the gallery.I have already tried shared preference, but I am pretty sure I did it wrong. It is in the code that I have below.

I am working on an Android Activity where I want to pass a Camera Intent to an Input Stream, in order to process it further through the Activity;
The aim is that the user can make a Camera picture and that the picture is then processed as an Input Stream and passed to an API.
I am not sure if that´s the best way to "convert" a Camera Image into an Input Stream, therefore I am open to any suggestion and hint; this is my code so far:

You can trigger a Camera intent and tell it where to save your picture, after that you can open the file as an InputStream. To do so you need to pass the file Uri like this:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
If you don't pass the File Uri you'll receive a thumbnail not the full size photo. For more details take a look a the docs:

This is one activity class of my android project and this activity depends on another utility class....which is mentioned below:
The statement Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap(); shows an error in "imageView" and the statement boolean result=userChosenTask.checkPermission(Crime.this); shows an error on "checkPermission"...but I don't understand why...because checkPermission is already defined in the utility class....

I am using com.paypal.android.MEP.PayPalActivity library. I want to edit layout but I can't access it. How can I edit default layout of this library. I am trying to transfer money from an account to another account. It works correctly but user interface seems bad
