Error : method gettext() must be call from UI thread is worker

While working on a project I'm getting this error
Error : method gettext() must be call from UI thread is worker
on the following line :
String url = Util.send_chat_url+"?email_id="+editText_mail_id.getText().toString()+"&message="+editText_chat_message.getText().toString();

Do not access the Android UI toolkit from outside the UI thread
Pass editText_mail_id.getText() and editText_chat_message.getText() as parameters to your async task or set it in onPreExecute to some variable
Like :
private class SendMessage extends AsyncTask<String, Void, String> {
private String mailId;
private String msgText;
#Override
protected void onPreExecute() {
super.onPreExecute();
mailId = editText_mail_id.getText().toString();
msgText = editText_chat_message.getText().toString();
}
Change url in doInBackground as :
String url = Util.send_chat_url+"?email_id="+mailId+"&message="+msgText;

you can create class for storing your parameter like i do,
Just create one class
example :
public class MyTaskParams
{
String mailId;
String message;
public MyTaskParams(String mailId, String message)
{
this.mailId = mailId;
this.message = message;
}
}
public class SendMessage extends AsyncTask<MyTaskParams, Void, String {
#Override
protected String doInBackground(MyTaskParams... params) {
String mailId = params[0].mailId;
String message = params[0].message;
String url = Util.send_chat_url+"?email_id="+ mailId +"&message="+ message;
}
}
so you can just call like this
MyTaskParams params = new MyTaskParams(editText_mail_id.getText().toString(),editText_chat_message.getText().toString());
SendMessage myTask = new SendMessage();
myTask.execute(params);
with this code you can call SendMessage Class from any activity, dont bind your asynctask with get text because if you do that you just can use SendMessage only in that activity
Hope this can help you.

run a service indefinitely

I am creating an application that sends and receives data from the server all the time. I need it to update the data as soon as possible, because every second is changing online data. I created this class, but it does not work, hangs at one time. Wonder if this "while (true)" is the correct way to do the functions run indefinitely because it does not find anything more like

My MainActivity that calls my IntentService

case SampleIntentService.DOWNLOAD_ERROR: {
Toast.makeText(getApplicationContext(), "error in download", Toast.LENGTH_SHORT).show();
pd.setVisibility(View.INVISIBLE);

break;
case SampleIntentService.DOWNLOAD_SUCCESS: {
String filePath = resultData.getString("filePath");
Toast.makeText(getApplicationContext(), "image download via IntentService is done", Toast.LENGTH_SHORT).show();
pd.setIndeterminate(false);

#Override
public void onClick(View v) {

Intent startIntent = new Intent(MainActivity.this, SampleIntentService.class);

pd.setIndeterminate(true);
}
public void onClick2(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "image download via IntentService is done", Toast.LENGTH_SHORT).show();
}
}
My JSON Class works fine, I tried it in another App and I got not error.
In my AndroidManifest.xml ...
I tried this:
<service android:name="com.example.pfecuspart.SampleIntentService"
android:exported="false">
<intent-filter>
<action android:name="org.example.android.myservicedemo.IService" />
</intent-filter>
</service>
I also tried this:
<service android:name="com.example.pfecuspart.SampleIntentService"
android:enabled="true">
</service>

I dont think onClick2 is doing anything, its not overriding the onClick.
do you need to move;
Toast.makeText(getApplicationContext(),
"image download via IntentService is done",
Toast.LENGTH_SHORT).show();
from onClick2, to onClick.
Maybe try replacing getApplicationContext() with MainActivity.this

Trouble with using OAuth LinkedIN for Android SDK

I am trying to run an OAuth in my android app to get user data from LinkedIn and as i just started on the project i have run into a major bug/issue. After requesting the token from the following code, the token doesn't get received and the app continues to open in the on-phone browser used for the authentication.
Any help would be appreciated as I am really new to android development.

AsyncTask is not working properly in android 4.0

I have this async Task on android 2.3.5
class InternetConnexionErrorAsync extends AsyncTask<String, String, String>

}
return null;
}
#Override

finish();
}
}
Everything is working well.
When I try this in Android 4.0, I am newer accessint the onPostExecute.
Could you please help me. No error message, only that the onPostExecute is newer reached.

Whatever you need to update on the UI you need to do in onPostExecute.
The code below, take a look at onPostExecute - specifically the activity.xx() methods send updates to the main activity that do things on the UI.
For example:

//Log.v(TAG, db.getUserDetails().toString());
}
//login failed, sent when LoginTask doInBg sends a 0 to onPostExecute
if (responseCode == 0) {
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context, "Incorrect username/password", duration);
toast.show();
}
if (responseCode == 2) {
//logout button clicked, listened from within LoginFragment
//remove user from active sql db here rather than LoginFragment?!
bar.getTabAt(0).setText(R.string.login);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, "Logged out", duration);
toast.show();
userFunctions.logoutUser(context);
}
}

The solution I adopted, after the suggestion of #Davek804 is that I replace the AsyncTask with a delayed runable like this:
private Runnable mMyRunnable = new Runnable()
{
public void run()
{
finish();
}
};
Toast.makeText(getBaseContext(),errorMessage , Toast.LENGTH_LONG).show();
Handler myHandler = new Handler();
myHandler.postDelayed(mMyRunnable, 3450);
So the effect will be the same.

I found the solution here
Instead of using :
task.execute();
use :
task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, null);
