Re: [android-developers] Re: Hello Everyone, i just have a quick question:
Uhmthe root of the error is at that line 87 of your BTD...Activity.
What's at that line?
is it: SetBluetoothDevice pairedDevices = mBtAdapter.getBondedDevices(); ?
ant it might be that mBtAdapter is null (by reading the docs it says that
BluetoothAdapter.getDefaultAdapter() returns null when bluetooth is not
supported -
http://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#getDefaultAdapter()
).
Maybe you are using the emulator to run this? (AFAIK the emulator doesn't
support bluetooth)
so, just add a if (mBtAdapter != null) { ... rest of your code .. }

Re: [android-developers] Re: Hello Everyone, i just have a quick question:
yes it's:
// Get a set of currently paired devices
SetBluetoothDevice pairedDevices = mBtAdapter.getBondedDevices();
So i wonder what's about it.
Just a question about the Log.e and Log.d
i added this:
if (D) Log.d(Tag, in onCreate());
if (D) Log.e(Tag, onCreate());
if (D) Log.i(Tag, onCreate());
Am i getting it right? because i can't see how the three are different (e:
Error, I: information, ) if it's me who has to specify the displayed
message...for example: in onCreate message.

?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=android.mgo.helloandroid
android:versionCode=1
android:versionName=1.0

Hi Soyer,
All your activity class has to be there in your Manifest.xml file
if you call your activity class from other activity then that class
has to be main( internt filter main) Please check these two point and
i think this will solve ur problem.
I am sure some problem in ur Manifest.xml file

Thanks guys for the help, Kris is it wrong if somebody try to learn something different, out of his field !! Thanks for the help though i really appreciate it. If a NullPointerException is out of your field, then your field certainly isn't programming Java. Students learn about this extremely quickly in even their first few classes of any introductory Java course. If your problem is that you haven't programmed in Java a lot, there are many resources available for learning Java development, and it would be best to learn this before trying to learn Android development. kris -- You received this message because you are subscribed to the Google Groups Android Developers group.

This is included in the program...

Also post your manifest here so we can make sure this isn't some silly thing with your activity not being included in the manifest.
