The sound like you forgot to add populate() in the constructor.
It should be like:
LocationItemizedOverlay(Drawable defaultMarker, Context context) {
super(boundCenterBottom(defaultMarker));
this.context = context;
populate(); // Add this
}
.....
Its happens on moving map
When I run my android application it gives an error "The application has stopped working,please try again". Please help me to solve this problem. i have created a method which gets called when the button gets clicked. When I include the code for calling another class in this method it shows the above error & when I remove that code it neither shows the error nor goes ahead when listview etc. gets clicked. Can you please check my code and help me please.
CODE:
public void myClickHandler(View view)
{
//Toast.makeText(this, "yesss",Toast.LENGTH_LONG).show();
setContentView(R.layout.screen1);
ListAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, city);
ListView FirstProjectActivity = (ListView) findViewById(R.id.mylist1);
FirstProjectActivity.setAdapter(adapter);
Intent myIntent = new Intent(FirstProjectActivity.this,
City.class);
FirstProjectActivity.this.startActivity(myIntent);
//startActivity(new Intent(FirstProjectActivity.this, City.class));
}

When you want to detect if you click on an item you need to implement the onItemClickedListener i will give you an example below like i would do it:
listView.setOnItemClickListener(new MyOnitemClickListener());
//no i make my own class that impelemnts the onitemclicklistener
public class MyOnitemClickListener implements OnItemClickListener {
private int position = 0;
public void onItemClick(AdapterView<?> parent, View view, int pos,
long lat) {
// clicked on parent.getid()
if (parent.getId() == R.id.listView) {
//do something
}
}
}
after a crash, try looking for the first couple of red lines the LOGCAT spews to you as they usually explain what happened.
the following line :
java.lang.NullPointerException
(in line 5) showed up on you log, it usually means your trying to use an uninitialized object.
refer to:
What is a NullPointerException, and how do I fix it?
I am working on android application and I am struck at the below error. Can anybody of you help me out with this error:
When I switch between activities in a tab I was able to do it for 2 times on 3rd time I get the error saying Sorry...application has stopped unexpectedly. Please try again.
I tried to take the info from LogCat file below is the information:

I tried to use logcat and got the above information.
Can anybody help me to find the solution I get the error only when I go to different activity on 3rd time. First 2 times it works fine.
Your UI is too complicated, and you are running out of stack space when trying to render it. Use Hierarchy View and try to reduce the number of layers between the root View of your activity and the farthest leaves.
