Stop Timer on return to previous Activity

I have created a timer that starts timing on a handleClick() and continues timing throughout the app. When I return to the firstActivity I would like the timer to stop in the onResume(). however whenever I return to the firstActivity I get the following error below. How do I solve this?
Error

Android: Why cant i save more objects in my arraylist

why is that when i make a touched pinpoint, it only takes the last pinpoints in the arraylist. When i measure the arraylist size, it says that the size is 1 even though I am saving 2 or more pinpoints.

You're adding the same Locations object to the list repeatedly in getData()... you're not instantiating a new object.
You probably really meant

android textview does not show after setting visible from another thread

I am having problems making my TextViews visible from another thread using the method showDisclaimer(). I have used runOnUiThread() to set the visibility of my TextViews. Basically, I want to show these views after importing the csv to the database. Can you take a look and see what I missed?

simplymoody, do what Chirag Raval suggested by declaring private static TextView homeText1, globally and in your onCreate initialise them. However, you should always update the UI from the main thread. But showDisclaimer() is still running on the background thread, so you could run the showDisclaimer() a couple of different ways. One would be to do what you have done in getUploadDate():
runOnUiThread(new Runnable() {
public void run() {
showDisclaimer()
}
});
Or you could use a handler:
private Handler showDisclaimerHandler = new Handler(new Handler.Callback() {
#Override
public boolean handleMessage(Message msg) {
homeText3x.setText("TEXT");
homeText1x.setVisibility(View.VISIBLE);
homeText2x.setVisibility(View.VISIBLE);
homeText3x.setVisibility(View.VISIBLE);
homeText4x.setVisibility(View.VISIBLE);
Log.d("ShowDisclaimer", "finished showing disclaimer");
return false;
}
});
And everywhere in a background thread you wish to run your showDisclaimer(), instead you run:
showDisclaimerHandler.sendEmptyMessage(0);
