We Keep Coding

When I click on next song my seekbar sometimes gets updated and sometimes not. I am not getting what's the error in my code probably with the seekbar

**Main Activity.java**
This is main activity where I instantiate all methods/objects. Here I use Dexter library to grab files from user's external storage, then I made one method called find songs which helps in finding the path of files and list them accordingly. Then I made another method called display songs which will help in getting the whole size of songs and then display the whole list with their names accordingly. Then with the help of custom adapter I passed my list of songs which is in array named item.

**PlayerActivity.java**
I tried to make a Thread named update seek bar which will update my seek bar to current position after that I applied set on click bar change listener so that whenever user update position of sidebar it should get updated. But error here is that when I run my app using this code on emulator its working completely fine but when installed in my phone 2 errors are coming. One after completion of song its not jumping automatically to the next song and second when user update sidebar and press next, sidebar is not coming to position 0, and this whole error is showing on my phone not in emulator.

Here is the logcat message:

Please give me some solution if possible.
I have used context.getBaseContext() but it also gave error.

Instead of parsing context to activity use getActiviy()
Intent intent = new Intent(getActivity(), AppActivity.class);

Try change this line
Instead
Intent intent = new Intent(context, AppActivity.class);
to
Intent intent = new Intent(YourActivityName.this, AppActivity.class);

Here, everything looks normal. But there is no the rest of the code. Maybe you create an activity every second.
I would recommend you to write in support of the admob and clarify the issues. Maybe you're lucky and they will unblock you.

Please help me how to add http post request on this code..
And also the php on the Server side .

For the Android HttpPost (to send JSON serialized data to a server)
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("url_of_the_server");
JSONObject json = new JSONObject();
json.put("name", name);
json.put("note", note);
StringEntity se = new StringEntity(json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(se);
HttpResponse response = client.execute(post);
//With response you can check the server return status code(to check if the request has been made correctly like so
StatusLine sLine = response.getStatusLine();
int statusCode = sLine.getStatusCode();
For more information on how to call a php web service there is a pretty nice tutorial that can be found here
