Hi all,
Thanks 4 ur reply.
Actually I want to call some methods of one Activity
(test.check.Test1.java) from another activity (my current activity) at
runtime in the separate Thread. In the main GUI Thread this works
fine.
This Test1.java activity resides in the test.check.apk file which is
Mariano : I have not used Looper.prepare(),
Is it required?? If yes then where and how to define
handler for that?
I honestly don't understand what you're trying to achieve, so it's hard to
answer that question.
I once tried to inflate GUIs in a separate thread for performance
yess right, in short i was trying to instantiate a view comp.
Still not clear logic for using Looper.
might be Google engineers can answer this.

Glad it works.
Well, what you were trying to instantiate was a View Component, weren't

Do it on the main thread.
If you want to actually run UI on another thread, read up
Maybe your example is simplified, but if this method you want to call
(xyz()) is really this simple (i.e. it does not really need a whole
activity and all its functionality (Looper and such)), refactor your
code and put this 'xyz()' in a class that is not an activity and refer
to this class by
A view is bound to the thread it is created in. (Actually not view itself,
but many subclasses have an internal Handler for scheduling work.) Yes, it
can be annoying in some cases, but that's the way it is.

Hi Dianne,
Is there any handler needed for that?? Any Idea???

Hi,
I am using Reflection APIs in the background thread to call a method

It could be that during the construction of class test.check.Test1, a
Handler or something similar (i.e. something needing the main-thread's
message-queue) is constructed. Look at your test.check.Test1
implementation and see if this is the case.
If this is the case, you will get an exception if
Hi Streets,
I dont think this is the case.
Same code executes nicely If I call that method in the onCreate()
method (i.e. main thread itself)
problem occurs in the Object creation if I will call this method
readTheFile() in the Thread.
Can you give any info. regarding how I can define Looper
I don't want to sound like a smart ass, but did you try what the error
message said?
Called Looper.prepare()?
I know I had a similar situation some time ago and it worked for me. Besides
the dreaded BufferedReader exception I find the exceptions I get from the
framework very helpful.
On Tue,
But do you want a Looper and Handler in your thread 't'?
Why do you load it in another thread?
Are you planning in dispatching and handling messages in this thread
't'?
If not, don't start adding all this stuff just to make the run-time
happy.
Put a breakpoint in your default constructor of
Also you need to look at the exception stack trace. It will show you who is
trying to create a Handler.
