    copied!<p>I am facing one problem in <code>AsyncTask</code> in my application in Android. The problem is, I am starting another <code>Activity</code> from <code>AsyncTask</code> in my application which runs fine when its layout has simple <code>Button</code>, but when I am using <code>ImageButton</code> its giving me error of handler and looper.loop. I am not getting the reason why this kind of error is occurring. I am displaying menus with images in calling <code>Activity</code>. </p> <p>Can anybody suggest me what is the problem in this and how can I achieve this kind of functionality?</p> <pre><code>protected void onPostExecute(Void result) { super.onPostExecute(result); if (Dialog != null &amp;&amp; Dialog.isShowing()) { Dialog.dismiss(); locationManager.removeUpdates(locationListener); Intent homeIntent = new Intent(ATMActivity.this.getApplicationContext(), HomeMenuActivity.class); homeIntent.putExtra("lat", latitude); homeIntent.putExtra("lng", longitude); startActivity(homeIntent); } } </code></pre> <h3>XML File :-</h3> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:orientation="vertical" &gt; &lt;ImageButton android:id="@+id/imageButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/atm_icon" android:onClick="buttonClicked" /&gt; &lt;/LinearLayout&gt; </code></pre> <h3>Another Activity Class :-</h3> <pre><code>protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.home); Button btn = (Button) findViewById(R.id.imageButton1); btn.setHint("ATM"); float latitude = getIntent().getFloatExtra("lat", 0); float longitude = getIntent().getFloatExtra("lng", 0); Toast.makeText(getApplicationContext(), "Location Floats:- " + latitude + "," + longitude, Toast.LENGTH_LONG).show(); } </code></pre>
