Android:ActivityNotFoundException

public void onContacts(View v)
{
    Intent i=new Intent(Intent.ACTION_VIEW, ContactsContract.Contacts.CONTENT_URI);
    startActivity(i);
}

public void onBrowse(View v)
{

    String s1= et1.getText().toString();
    Intent i= new Intent(Intent.ACTION_VIEW, Uri.parse(s1));
    startActivity(i);

}

public void onSearch(View v)
{

    String s1= et2.getText().toString();
    Intent i=new Intent(Intent.ACTION_WEB_SEARCH);
    i.putExtra(SearchManager.QUERY, s1);
    startActivity(i);
}

public void onMap(View v)
{

    String s1= et3.getText().toString();
    Intent i=new Intent(Intent.ACTION_VIEW,Uri.parse("geo:0,0?q="+s1));
    startActivity(i);
}

These are few methods each attached to respective buttons, on clicking any of these button it shows ActivityNotFoundException except the onContacts() method which is not attached to any editext...

I think your problem is that there is no Activity for handle the Intent.ACTION_VIEW and Intent.ACTION_WEB_SEARCH actions, to check if there is an Activity for handle your intent you could check this before:

PackageManager packageManager = getPackageManager();
List<ResolveInfo> activities = packageManager.queryIntentActivities(intent, 0);
boolean isIntentSafe = activities.size() > 0;

if the number of Activity in List activities is 0 that means that there is no Activity for handle your Intent by the moment, before trying to start an Activity you should check this first..

EDIT: as we know those Actions are common to android device (maps and web browser), due to this you should check if the URI you are pasing are correct.

Your Intent URI is wrong. Or rather the content of your TextView isn't constructed in a way which will open the search dialog you're expecting. Try, for example, entering:
