Uploading Image from android to PHP server
Use below code. It will do the same.
public class UploadImage extends Activity {
InputStream inputStream;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.icon); ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.
byte [] byte_arr = stream.toByteArray();
String image_str = Base64.encodeBytes(byte_arr);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("image",image_str));
Thread t = new Thread(new Runnable() {
@Override
public void run() {
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("server-link/folder-name/upload_image.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
String the_string_response = convertResponseToString(response);
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(UploadImage.this, "Response " + the_string_response, Toast.LENGTH_LONG).show();
}
});
}catch(Exception e){
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(UploadImage.this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();
}
});
System.out.println("Error in http connection "+e.toString());
}
}
});
t.start();
}
public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{
String res = "";
StringBuffer buffer = new StringBuffer();
inputStream = response.getEntity().getContent();
int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(UploadImage.this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();
}
});
if (contentLength < 0){
}
else{
byte[] data = new byte[512];
int len = 0;
try
{
while (-1 != (len = inputStream.read(data)) )
{
buffer.append(new String(data, 0, len)); //converting to string and appending to stringbuffer…..
}
}
catch (IOException e)
{
e.printStackTrace();
}
try
{
inputStream.close(); // closing the stream…..
}
catch (IOException e)
{
e.printStackTrace();
}
res = buffer.toString(); // converting stringbuffer to string…..
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(UploadImage.this, "Result : " + res, Toast.LENGTH_LONG).show();
}
});
//System.out.println("Response => " + EntityUtils.toString(response.getEntity()));
}
return res;
}
}
PHP Code
<?php
$base=$_REQUEST['image'];
$binary=base64_decode($base);
header('Content-Type: bitmap; charset=utf-8');
$file = fopen('uploaded_image.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo 'Image upload complete!!, Please check your php file directory……';
?>
UPDATE
NameValuePair and Http Classes are deprecated so, I've tried this code and it's working for me. Hope that helps!
