[android-developers] HandlerThread the right way ?

[Grunk]

Hello,

I'm using HandlerThread like below in my app. Is it correct ?


public class MyThread extends HandlerThread implements Callback
{
public ThreadDP(Handler uiHandler)
{
super(MyThread.class.getSimpleName(), Process.
THREAD_PRIORITY_DISPLAY);
mUiHandler = uiHandler;
this.start();
}


@Override
protected void onLooperPrepared()
{
super.onLooperPrepared();
synchronized (this) {
mThreadHandler = new Handler(getLooper(),this);
notifyAll();
}
}


public LabelList getLabels()
{
//Get some datas from network
return labels;
}


@Override
public boolean handleMessage(Message msg) {


Message message;
Bundle bundle;


switch (msg.what)
{
case ThreadMessages.GET_LABELS : 


message = mUiHandler.obtainMessage();
message.what = ThreadMessages.GET_LABELS;


Bundle bu = new Bundle();
bu.putInt("myapp.idThread", mIdThread);
bu.putParcelable("myapp.label", this.getLabels());
message.setData(bu);
this.uiHandler.sendMessage(message);
return true;
}
}
}


And then : 

mThread = new MyThread(uiHandler);
mThread.start();
mThread.getHandler().sendEmptyMessage(ThreadMessages.GET_LABELS);

The communication between the thread and UI is going pretty well , but i'm 
little confused by the lack of runnable. Should is keep using this way or 
am i missing something important ? 

Thanks

A negative confirmation is better than nothing, so thanks for that.  At

[android-developers] Replacing the settings menu(...) with button items.

[Clint William Theron]

Hi power code writers:-)
I chose one of your templates (I think it's the blank or empty one) and I 
really like the top-right menu, it's the one with the three dots vertically 
on top of each other. Anyway, when we tap this button a popup container 
appears with the word settings in it. I hope you know exactly to which 
button I'm referring to. Now instead of the word settings I would like to 
replace that with 3 buttons in that container. So when I click the 3 
vertical dots (...) the three buttons should popup. The button's icons will 
be replaced with my icons. 
Can we do this? Let me know how to do this and
thank you in advance.

[android-developers] help on setting Android Studio in a pc with SDK installed

[Angelo Giammarresi]

Hello,

I have already installed in my PC Android SDK till v 20 because previously 
used with Eclipse 3.7.2

I want to install Android studio now.
If I download the bundle will it erase previoslu SDK version or only update 
the folders adding new missing version?
Is better download only Android Studio and later update SDK from inside it?

Thanks
