A gentle advice and a precaution for all the future exception you might encounter ----> handle any/just UI operations in ui thread like this `runOnUiThread(new Runnable(){ Timer.setText(i); } );` — BlackBeard, Sep 04 '14 at 10:24

You have to set the text like this

Timer.setText(i + "");

This is because the setText(int resId) version will be invoked when you pass in an int value when you really wanted to invoke the setText(String text) version

The compiler/IDE does not give an error here. The int version looks for a corresponding String resource which doesn't exist and gives you the error.

Check this link for mode info TextView.

change

Timer.setText(i);

to

Timer.setText(String.valueOf(i));

Here i is an Integer value. You cann't assign Integer value as TextView text you have to convert it to String first.

If you explain why to the OP, your post will probably attract more votes. – Michael Sep 04 '14 at 10:05
If I change to Timer.setText(String.valueOf(i)); then also the same problem the program is not executing comes out. – Veera Prasad Sep 04 '14 at 11:05
At first first i converted to string and executed that also did not work. – Veera Prasad Sep 04 '14 at 11:09
If u run the above code in eclipse u will find the error. – Veera Prasad Sep 04 '14 at 11:13
Instead of Timer.setText(String.valueOf(i));I have changed with Toastmessage. Toast.makeText(MainActivity.this, i, Toast.LENGTH_SHORT).show(); Still its throws the error msg.' – Veera Prasad Sep 04 '14 at 11:16
