Touchscreen not responding for my app
<p>I'm working on a android app. It has two buttons in the start up screen, on click of which will give us a pop-up menu. When I try to run the app in emulator it works fine, even it works fine when I try on HTC Explorer, but the app doesn't respond in Kindle and Tablets. It displays the start up screen, but the touchscreen doesn't respond when I click on buttons.
Whereas other apps are working fine. I can tell that it is not the hardware issue. 
What may be the issue with that? Please help</p>

<p>This is the code where I'm calling the menu:</p>

<pre><code>public void onClick(View v) {
        // TODO Auto-generated method stub
        if(v.getId() == mSOS.getId())
        {
            showSosLists();

        }
        else if(v.getId() == mMainMenu.getId())
        {
            openOptionsMenu();
        }

    }

    @SuppressLint("NewApi") private void showSosLists() {
        // TODO Auto-generated method stub
        mListNames.clear();
        if(mPreference.contains("medicallist") &amp;&amp; mPreference.getStringSet("medicallist", null) != null)
        {
            mListNames.add("Medical");
        }
}
</code></pre>
