    <p>I am developing one application in which i am getting an exception, and i know this one is the silly or small mistake which i am doing but your help may catch me out and make my day:</p> <pre><code>public class Demo extends Activity { Button btnDemo; Thread t; AlertDialog alertDialog; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.demo); btnDemo = (Button) findViewById(R.id.btnDemo); btnDemo.setOnClickListener(new OnClickListener() { public void onClick(final View v) { t=new Thread() { public void run() { tryDemo(); } }; t.start(); } }); } public void tryDemo() { try { int i = 5; if(i == 0 || i == 1) { Intent intent_success = new Intent(getApplicationContext(), Main_Activity.class); startActivity(intent_success); } else { alertDialog = new AlertDialog.Builder(getApplicationContext()).create(); alertDialog.setTitle("Demo"); alertDialog.setButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { //here you can add functions } }); alertDialog.setIcon(R.drawable.icon); alertDialog.setMessage("Sorry!! Either Username or Password Invalid"); alertDialog.show(); } } catch(Exception e) { Log.i("Demo", "Demo - Demo Exception"); } } } </code></pre> <p>In above code, if i make i=0 or i=1 in tryDemo function then it is running successfully , but if i make it other than 0 or 1 then it <strong>throws an exception as "Demo - Demo Exception"</strong>.</p> <p>I am not sure but i think the exception raises from <strong><em>getApplicationContext()</em></strong>.</p> <p><strong>Update:- 1</strong></p> <p>The exception which i am getting, as follows:</p> <p><img src="https://i.stack.imgur.com/1ggK5.png" alt="alt text"></p> <p><strong>Update:- 2</strong> If I remove the "thread" part and wrote the whole function code in the button click event and replaced the "getApplicationContext()" with v.getContext() then it is running successfully.........but i want to implement it within the THREAD.</p> <p>Please help me and catch me out...</p> <p>thanx</p>

    1. COIn your catch, put e.printStackTrace(). That will give you the line number the error is on. This will give you more information at least.

    2. COHow about Log.i("Demo", "Demo - Demo Exception", e); so we can actually see what the exception is and tell you what's wrong?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
