My problem is the next ...
Im trying to display a image, that is defined in my phpmyadmin, and hosted in the correspondient folder, but the bitmapfactory returns nothin.
MY JAVA:
if (success == 1) {
// successfully received product details
JSONArray productObj = json.getJSONArray(TAG_PRODUCT); // JSON Array
// get first product object from JSON Array
JSONObject product = productObj.getJSONObject(0);
// product with this pid found
// Edit Text
txtName = (EditText) findViewById(R.id.inputName);
txtPrice = (EditText) findViewById(R.id.inputPrice);
txtDesc = (EditText) findViewById(R.id.inputDesc);
// display product data in EditText
txtName.setText(product.getString(TAG_NAME));
txtPrice.setText(product.getString(TAG_PRICE));
txtDesc.setText(product.getString(TAG_DESCRIPTION));
//imageview
imageView1 = (ImageView)findViewById(R.id.imageView1);
imagen_url=product.getString("TAG_IMAGEN");
String imagen_url2=product.optString("TAG_IMAGEN");
byte[] encodeByte = Base64.decode(imagen_url, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
imageView1.setImageBitmap(bitmap);
AND THE PHP
$product["imagen"] = base64_encode($result["imagen"]);
It returns a error:
04-10 04:12:32.344: W/System.err(1424): org.json.JSONException: No value for TAG_IMAGEN

The problem was the TAG, if I put :
imagen_url=product.getString("imagen");
works, but with not :
imagen_url=product.getString("TAG_IMAGEN");
I dont know why, but with this change, it works fine!

I've an error that occur when I try to fix it but it doesn't fix.
JSONArray application_band =jsonResponse.getJSONArray("banda");
String [] list = new String[application_band.length()];
for(int i = 0; i<application_band.length(); i++){
list[i] = application_band.getString(i);
}
And this when I create the intent:
if (hurado_section ==1) {
Intent intent = new Intent(LoginActivity.this, CategoryOneActivity.class);
intent.putExtra("hurado_name", hurado_name);
intent.putExtra("hurado_id", hurado_id);
intent.putExtra("hurado_section", hurado_section);
intent.putExtra("application_band",list);
LoginActivity.this.startActivity(intent);
}
Error:
07-20 16:47:10.781 27808-27808/com.example.cursoft.scoringsystemseu W/System.err: org.json.JSONException: No value for banda
What could be the problem?
So I came over this tutorial right here https://www.youtube.com/watch?v=mdAXqQoADt8 (last part of it) everything is working absolutly fine when I'm refering to my local server.
Now I switched it up to an online server/database to test if it works the same way. Also here everything is working fine except of the json response in the onPostExecute Method. I'm getting no messages from registration or login anymore. I really can't figure out how to solve this problem and I don't understand why it doesn't work the same way when I switch it up to an online server/database.
Hope anyone here can help me with that. I'll post some code below, maybe somebody can figure it out without doing the whole tutorial.
Thankful for any help!

It seems you're getting wrong JSON string from the server.

The Json response you receive is not formatted as JSON it contains invalid character '<!--' thats why your jsonparser throw an Jsonexception.
Try to save your php file in cp1252 Encoding
Open your php file in Eclipse
Edit> Set Encoding then set to cp1252
save
hi i use this tutorial for connecting to the mySQL db on the web or local.
here
although the all server side php files are correct and works on the browser, but in Android side the app crashes on this line:
JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);
with this message: unfortunately app has stopped!
i find out on tutorial page comments that i should change some setting on apache server.
here is my code:

how i can solve this problem?
If you are referring to a localhost from your device than use the http://10.0.2.2:8080/ instead of the http://127.0.0.1/ or http://localhost/.
Because your Android emulator is running on a Virtual Machine(QEMU) and you can not connect to a server directly running on your PC.
And If you running your app from Physical android device then please use your network ip from your PC.
for example http://198.10.12.21:80/....
This is my doInBackground
protected Integer doInBackground(String... args) {
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("username", Username));
params.add(new BasicNameValuePair("password", Password));
Log.d("request!", "starting");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST", params);
Log.d("Login attempt", json.toString());
success = json.getInt(TAG_SUCCESS);
res = json.getString(TAG_MESSAGE);
loginposition = json.getJSONArray(TAG_POSTS);
for (int i = 0; i < loginposition.length(); i++) {
JSONObject c = loginposition.getJSONObject(i);
Position = c.getString(TAG_POSITION);
}
} catch (JSONException e) {
Log.e(TAG, "JSON error", e);
success = Integer.valueOf(0);
}
return success;
}
I declare the Position variable as String Position and I don't know why my android json said my success is not 1 or null.. even my tag post.
This is my logcat

You are getting a String[] in your posts and you are trying to cast it to JSONObject which is giving you exception.
Try replacing
JSONObject c = loginposition.getJSONObject(i);
to
String jsonText = loginposition.getString(i);
If
"loginposition is JSONArray type yes and Position is a string variable that responsible to save the string like user and staff from my database"
and you have this json:
{"posts":["user"],"message":"Login Successful!","success":1}
you can do this:
//loop through all the entries in loginposition and extract strings for each index
for (int i = 0; i < loginposition.length(); i++) {
position = loginposition.getJSONObject(i);
}
If your json contains more than one user, eg. ["user", "staff"], this loop will go through all of them, so you need to handle this accordingly.
NOTE: remember that by Java convention, you should use variable names with lower case first letter (so 'position' not 'Position').
