PHP – Android uses the volley library to upload images to the server
•
Android
I want to use the volleyball library to upload my images from the camera to my 000webhost.com server
I want to find out what went wrong and suggest a complete code solution
I tried to write code, but it didn't work
I received the following error:
D/URL﹕ http:/plantNow.net16.net/uploaded.PHP
D/ERROR﹕ Error [com.android.volley.NoConnectionError: java.net.UnkNownHostException:
My PHP uploaded.php looks like this. I want to destroy the image and image path in the server
<?PHP
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$image = $_POST['image'];
require_once('dbconnect.PHP');
$sql ="SELECT id FROM images ORDER BY id ASC";
$res = MysqLi_query($con,$sql);
$id = 0;
while ($row = MysqLi_fetch_array($res)) {
$id = $row['id'];
}
$path = "uploadedimages/$id.jpeg";
$actualpath = "http://plantNow.net16.net/$path";
$sql = "INSERT INTO images (image) VALUES ('$actualpath')";
if (MysqLi_query($con,$sql)) {
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
}
MysqLi_close($con);
} else {
echo "Error";
}
?>
My main activity is skydiving. The code is as follows:
public class MainActivity extends Activity {
ProgressDialog prgDialog;
String encodedString;
String fileName;
private static int RESULT_LOAD_IMG = 1;
private Button buttonUploadPhoto;
private ImageView myimage;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
prgDialog = new ProgressDialog(this);
// Set Cancelable as False
prgDialog.setCancelable(false);
buttonUploadPhoto = (Button) findViewById(R.id.uploadPhoto);
myimage = (ImageView) findViewById(R.id.imgView);
buttonUploadPhoto.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
uploadImage();
}
});
}
public void loadImagefromGallery(View view) {
// Create intent to Open Image applications like Gallery, Google Photos
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// Start the Intent
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
}
// When Image is selected from Gallery
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
String fileNameSegments[] = picturePath.split("/");
fileName = fileNameSegments[fileNameSegments.length - 1];
Bitmap myImg = BitmapFactory.decodeFile(picturePath);
myimage.setImageBitmap(myImg);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
// Must compress the Image to reduce image size to make upload easy
myImg.compress(Bitmap.CompressFormat.PNG, 50, stream);
byte[] byte_arr = stream.toByteArray();
// Encode Image to String
encodedString = Base64.encodeToString(byte_arr, 0);
uploadImage();
}
}
/**
* API call for upload selected image from gallery to the server
*/
public void uploadImage() {
RequestQueue rq = Volley.newRequestQueue(this);
String url = "http:/plantNow.net16.net/uploaded.PHP";
Log.d("URL", url);
StringRequest stringRequest = new StringRequest(Request.Method.POST,
url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
Log.e("RESPONSE", response);
JSONObject json = new JSONObject(response);
Toast.makeText(getBaseContext(),
"The image is upload", Toast.LENGTH_SHORT)
.show();
} catch (JSONException e) {
Log.d("JSON Exception", e.toString());
Toast.makeText(getBaseContext(),
"Error while loadin data!",
Toast.LENGTH_LONG).show();
}
}
}, new Response.ErrorListener() {
@Override
public void one rrorResponse(VolleyError error) {
Log.d("ERROR", "Error [" + error + "]");
Toast.makeText(getBaseContext(),
"Cannot connect to server", Toast.LENGTH_LONG)
.show();
}
}) {
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("image", encodedString);
params.put("filename", fileName);
return params;
}
};
rq.add(stringRequest);
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
// Dismiss the progress bar when application is closed
if (prgDialog != null) {
prgDialog.dismiss();
}
}
This seems to me to be a typo
Try to change:
String url = "http:/plantNow.net16.net/uploaded.PHP"
To:
String url = "http://plantNow.net16.net/uploaded.PHP"
