    <p>Once solution that i would propose is this</p> <p>Create a class called callAlertBox.java like this</p> <pre><code>public class callAlertBox { private static Activity activity ; public static Activity getActivity() { return activity; } public static void setActivity(Activity mactivity) { activity = mactivity; } public static void showMyAlertBox(){ AlertDialog ad = new AlertDialog.Builder(activity).create(); ad.setCancelable(true); // This blocks the 'BACK' button if false ad.setMessage("Hello World"); ad.show(); } } </code></pre> <p>And now in every activity that might call this alert box place this code on its onResume() method</p> <pre><code>@Override protected void onResume() { super.onResume(); callAlertBox.setActivity(Act1.this); } @Override protected void onResume() { super.onResume(); callAlertBox.setActivity(Act2.this); } </code></pre> <p>Now you can call </p> <pre><code>callAlertBox.showMyAlertBox(); </code></pre> <p>from any activity and you will get the alert box</p> <p><em><strong>EDIT</em></strong></p> <p>The MainActivity.java file</p> <pre><code>public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button btn1 = (Button) findViewById(R.id.button1); btn1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { startActivity(new Intent( MainActivity.this,Act1.class)); } }); Button btn2 = (Button) findViewById(R.id.button2); btn2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { startActivity(new Intent( MainActivity.this,Act2.class)); } }); Button btn3 = (Button) findViewById(R.id.button3); btn3.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { startActivity(new Intent( MainActivity.this,Act3.class)); } }); new CountDownTimer(365 * 24 * 60 * 60, 5000) { public void onTick(long millisUntilFinished) { callAlertBox.showMyAlertBox(); } public void onFinish() { //Done } }.start(); } @Override protected void onResume() { super.onResume(); callAlertBox.setActivity(MainActivity.this); } } </code></pre> <p>Now you can see from here my Countdown timer will call the method in the background casuing the dialog to appear independent of which ever activity you are in, In my case it was the main Activity and in you case there might be some updating method that is frequently called right ?? Just use that class to call the method</p>

    1. COThanks for response but How would I decide that which activity will call showMyAlertBox(), because I am getting the response on one activity and right now I am on some other activity?

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.
