Emre,
Ok, good, so that's your logcat stack trace for the crash.
And it has the whole story about the crash.
The "what happened" is this:
11-12 12:34:15.666: WARN/dalvikvm(510): threadid=3: thread exiting
with uncaught exception (group=0x40013140)
The "what it its immediate cause" is this:
11-12 12:34:15.696: ERROR/AndroidRuntime(510):
java.lang.NullPointerException
The "where things went wrong" is this:
11-12 12:34:15.696: ERROR/AndroidRuntime(510): at
com.android:sample.SampleConnection.updateWithNewLocation(SampleConnection.java:275)
Look in SampleConnection.java, line 275, you should see your
updateWithNewLocation method (modified sample?). On that line, you will
find code that uses a null reference.

I have initialized the TextView for which I am setting the text.
However, I now have an idea why this situation might have occured.

PS. SampleConnection class updates the location on the display as it
changes.

Not much !!! :) In Java, NullPointer is pretty too much.
You might not have initialized the TextView for which you are setting
the text. Look into the logcat for more details. It will give you the
line number where this exception is being generated.

What does it complain about? Look at your logcat.

Hi,
I have created a Tab Layout based on the sample code given in
the "Tutorials" section on the Android website. I have two
Tabs with two Activities for each one of them.
All I want to do is to update a "TextView" variable that
belongs to a layout of one of the Activities when needed using
the setText() method (for whichever activity being displayed
at that moment).
However it keeps on complaining during runtime and thus the
text is never set. I was able to achieve this display update
when I was using a single layout by just setting the text of
the mentioned TextView variable. It should have something to
do with the Tab Layout, but what ?
Any ideas ?
Cheers,
Emre
