                try {
                    synchronized (this) {

                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
    开发者_如何学Go            postInvalidate();
            }
        }
    }).start();
}

when i execute the above method it gives me the below error.

05-27 08:52:56.910: ERROR/AndroidRuntime(12715): FATAL EXCEPTION: main
05-27 08:52:56.910: ERROR/AndroidRuntime(12715): java.lang.OutOfMemoryError: bitmap size exceeds VM budget

Does any one have any idea how to keep refreshing the screen every second without getting this error. ( in the canvas i draw a bitmap there. This says that bitmap causes this error )

There is an memory leak in your application. postInvalidate() causes the the whole ViewGroup to be redrawn. It's possible that a weak reference to your bitmap remains somewhere, or a weak reference to an Activity / View is present in the Heap which the GC can't free.

Since you have not posted much code, here is a link on how to trace the leaks in your application.
