I'm working on uploading multiple images. I can pick an image from my phone's sd card but when I'm trying to upload it to my database, the progress dialog shows "Uploading" only and after that it is being dismissed. Honestly, I'm not sure on my php code. Hope someone can help me :)
Here's my uploadActivity.java:
@SuppressLint("NewApi")
public class MainActivity extends Activity {
private Button upload, pick;
private ProgressDialog dialog;
MultipartEntity entity;
GridView gv;
int count = 0;
public ArrayList<String> map = new ArrayList<String>();
Bundle b;
TextView noImage;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
.permitAll().build();
StrictMode.setThreadPolicy(policy);
b = getIntent().getExtras();
noImage = (TextView) findViewById(R.id.noImage);
upload = (Button) findViewById(R.id.btnUpload);
pick = (Button) findViewById(R.id.btnPicture);
gv = (GridView) findViewById(R.id.gridview);
gv.setAdapter(new ImageAdapter(this));
if (b != null) {
ArrayList<String> ImgData = b.getStringArrayList("IMAGE");
for (int i = 0; i < ImgData.size(); i++) {
map.add(ImgData.get(i).toString());
}
} else {
noImage.setVisibility(View.VISIBLE);
}
upload.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
new ImageUploadTask()
.execute(count + "", "pk" + count + ".jpg");
}
});
pick.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i3 = new Intent(MainActivity.this, UploadActivity.class);
startActivity(i3);
}
});
}
class ImageUploadTask extends AsyncTask<String, Void, String> {

@Override

int i = Integer.parseInt(params[0]);

HttpClient httpClient = new DefaultHttpClient();

entity = new MultipartEntity();

bitmap.compress(CompressFormat.JPEG, 100, bos);
byte[] data = bos.toByteArray();
entity.addPart("user_id", new StringBody("199"));

}
return sResponse;

@Override

if (sResponse != null) {
Toast.makeText(getApplicationContext(),
sResponse + " Photo uploaded successfully",
Toast.LENGTH_SHORT).show();
count++;
if (count < map.size()) {

+ ".jpg");
}
}

and here's my uploads.php:
<?php
if($_SERVER['REQUEST_METHOD']=='POST'){
$image = $_POST['club_image'];
$userid=$_POST['user_id'];
$clubid=$_POST['club_id'];
require_once('connection.php');
$sql ="SELECT * FROM photos ORDER BY id ASC";
$res = mysqli_query($con,$sql);
$id = 0;
while($row = mysqli_fetch_array($res)){
$id = $row['id'];
}
$path = "uploads/$id.jpg";
$actualpath = "http://iguideph-001-site1.btempurl.com/PhotoUpload/$path";
$sql = "INSERT INTO photos (image) VALUES ('$actualpath')";
if(mysqli_query($con,$sql)){
file_put_contents($path,base64_decode($image));
echo "Successfully Uploaded";
}
mysqli_close($con);
}else{
echo "Error";
}
?>
