[android-developers] Better way to debug when there is jar dependancies?
My application app depends on jar_a, which depends on jar_b. Now I want to debug jar_b by changing it's code. Both the jar_a and jar_b is built by ant tool. So my process is: 1) change jar_b 2) build jar_b 3) copy jar_b to the lib/ directory of jar_a 4) build jar_a 5) delete the reference to jar_a and jar_b in eclipse (Properties of project) of app 6) re add the jar_a and jar_b into the eclipse It's really painful, I don't know if I am doing the right way?

[android-developers] What the difference of this pointer?
I see some of the examples contain such code to refer to this pointer: mProgressDialog = new ProgressDialog(AlertDialogSamples.this); So this usage has some special meaning other than the standalone this?

[android-developers] Re: Can't use the findViewById() in an second view
It's weird, if I change the code into:
new
DialogInterface.OnClickListener() {
public void
onClick(DialogInterface dialog,
int whichButton) {
String
user;
String
password;
setContentView(R.layout.alert_dialog_text_entry);
EditText user_edit = (EditText)findViewById
(R.id.username_edit);
EditText password_edit = (EditText)findViewById
(R.id.password_edit);
user =
user_edit.getText().toString();
setContentView(R.layout.main);
}
Then the button in the main view has no effect at all, is it a bug? Or
the way I do is wrong?

[android-developers] Re: Can't use the findViewById() in an second view
Finally I resolved this problem by invoking the flattened view's
findViewById(), hope this can be helpful for others.

[android-developers] How can the user event callback be invoked?
See:
public class CompassActivity extends Activity implements Renderer,
SensorEventListener {
The CompassActivity implements SensorEventListener and override the
onSensorChanged() method. I am curious when the hardware accelerator
is moving, how can the system invoke this callback? I mean how can the
Compass application register itself to the system so that the system
can know it has the registered callback need to be notified when the
events happen?
Thanks.

[android-developers] Some of the strange JAVA syntax - android specifics?
I am a C programmer before, and I am looking into android source code
right now, some JAVA syntax is confusing, I am not sure whether or not
it's android related, see:
@Override
protected void onDraw(Canvas canvas) {
synchronized (this) {
if (mBitmap != null) {
final Paint paint = mPaint;
final Path path = mPath;
final int outer = 0xFFC0C0C0;
final int inner = 0xFFff7010;
1) What's the meaning of Override? Is it ommitable?
2) What does the synchronized mean?
Thanks.
