I think you are trying to display Toast message inside the AsynTask doInBackground() method,
just do it in onPostExecute() method....
You might be using some background thread which is directly trying to make change in your main thread, if that is the issue then use
runOnUiThread(new Runnable() {
public void run() {
//do your work here
}
});

My app crashes when trying to verify username and password from mySQL database (logging in). This is verified on an AsyncTask method. It works fine on the normal Eclipse emulator. Are there any settings or tweaks to be done? Does it crash coz of the AsyncTask, or is there any other factor?
Here's the logcat:

installed XAMPP server, created database and successfully accessed it from chrome browser as well as from android emulator. However whenever i try to run application from my Samsung device, its refusing to connect my IP address.
My IP address is not registered in DNS.
I tried:
1) accessing from url- 127.0.0.1 and localhost
2) modified httpd.conf and httpd-xampp.conf file- changed to Require all granted permission
3) uninstalled my Antivirus
4) changed firewall and proxy setting
5) Created new Inbound Rule in firewall advance security
6) re typed INTERNET permission
7) wrote httpPost.setHeader("Accept", "application/json"); in code
Still Im getting following error:

Please try to check your local IP address of your PC. Connect the phone to the same network (WIFI). Then use the following address/port to connect to your PC.
In Android:
URL: your_pc_local_ip
PORT: 80 (but I think it is not mandatory)
I use in this way and it is working properly for me.

I have Views that show info from a database using a get cursor method. What I want to know is how to get the position id, like you would in a listview. they have the AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();, item being MenuItem, type of method the problem is it doesn't seem to work in just a regular view. Is there a method similar to the AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); for just a regular view?

Is there a method similar to the AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); for just a regular view?
No. If you, say, elect to pour Cursor data in to a TextView, you need to track what position or _id you used yourself. After all, you were the one who chose which position or _id to move to -- Android has no way of knowing if you populate a TextView from a Cursor or something else.
I have an activity that is formed of 2 tabs. The problem is, when I have this code:
tabHost.setCurrentTab(0);
I am getting the following exception:

However, if I change the second tab to be displayed by default (I have only 2 tabs), as in:
tabHost.setCurrentTab(1);
everything is displayed correctly and I am able to switch between the tabs as well. This tells me that the tabs are configured correctly somehow, but then, why this behavior ?
I realized what I was doing wrong: the Tab mechanism was working ok, it was a ListActivity implemented for the first tab that was causing the NPE.
