[android-developers] Request for developers HTC G1 (T-Mobile) review
Hi Android developers, Can someone make a brief review of G1 mobile from a developer point of view? Think about: - G1 features not working properly - issues when uploading custom applications - does an application running in the emulator behaves as expected in the real mobile (G1)? - is it a true open source OS or are there some restrictions? - issues when compiling the Android OS source code from scratch and updating the G1 OS - ... many thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Displaying contact Email address in a List in ListActivity
Hello all,
Happy New Year!
I'm a newbie trying to display a list of contact details in a
ListActivity. What is the best way to retrieve the Contact Name, Email
address and phone number and display it in a ListActivity?
Here's what I have so far... (Obviously in a half-cooked form)
Cursor c = getContentResolver().query(People.CONTENT_URI, null,
null, null, null);
startManagingCursor(c);
String[] from = new String[] {People.NAME, ?EMAIL COLUMN?,
?PHONE
COLUMN?);
int[] to = new int[]{R.id.name, R.id.email, R.id.phone};
SimpleCursorAdapter adapter = new SimpleCursorAdapter
(this,R.layout.contact_row,c,from,to);
setListAdapter(adapter);
Any help would be much appreciated
thanks, cheers,
Rohit

[android-developers] How to connect android to Google App Engine
I have spent two days trying to decide on a way to upload and download data to the Google App Engine. Do I use REST or simple HTTP post/get? Do I use JSON or XML? Do I use java or Python. I am thinking probably use python and probably use REST. But which one out there? There are so many to choose from. None seem to work out-of-the-box, but need faffing around with bits of code from here and bits of code from there. And is not clear at the outset what am taking on or what the limitations are. Can anyone point me at a usable system for connecting my Android to the GAE? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: String being truncated when its long
I think you are hitting a capacity limit of the android and should
chunk it somehow at say 3000 chars and store the chars somewhere not
in memory.

[android-developers] Re: Using eclipse
If you create a project from existing source, Eclipse uses the folder wherever it is. ie it does NOT ship them into your workspace. Means you can easily end up with source folders scattered far and wide. I made the mistake of using dropbox which stores in the cloud to create a project from. Result? Mass confusion (I was trying & failing to use same source for 2 PCs!). Eclipse needs careful watching and its not easy to track where your source folders are unless you have a good memory or check in properties, resource every time. All the best with it :) On Sep 2, 3:19 pm, Paul Hartie wrote: > Have been using eclipse to build my first few apps without any trouble > however recently when I try to create a new project I get the > following 2 problems before I change anything or add any code. > > Project is missing required source folder gen > The project cannot be built until build path errors are resolved > > I don't think I changed anything to make this happen but I could be > wrong.

[android-developers] Re: How to "printf" in android development
Use:
Log.d("my tag" ," here we are");
System.out etc does not work in Android AFAIK.
Then look at it in DDMS (its a special debugger, but very good when
you find it).
Works in emulator and device.

1) I get this too in WIndows Vista.

It works but is time consuming and then Eclipse keeps that odd folder you just made as source (wot an idiot!) - so I copy the project and it ends up in workspace once again. Phew.

Answering my own question here: The manifest attribute: android:screenOrientation="nosensor" is ideal. What it does is fix the screen orientation to the preferred one. This is great because Honeycomb it chooses landscape and other phones - well whatever is the default orientation.

[android-developers] Cannot handle exception in a thread
I am spinning a thread to go online and get data. But if phone is in a
network hole (no signal) it throws an exception.
In the exception I try to call Toast or finish() the activity but both
those cause a crash.
Here's the error and my code:
error is:
06-14 11:32:01.691: ERROR/AndroidRuntime(7389):
java.lang.RuntimeException: Can't create handler inside thread that
has not called Looper.prepare()
here is the code, note the catch clause at the end which is where my
problem lies:
*
private Thread checkUpdate = new Thread() {
public void run() {
try {
URL updateURL = new URL("http://search.twitter.com/
search.json?q="+string_from_speaker);
URLConnection conn = updateURL.openConnection();
...
} catch (Exception e) {
// none of these exception handlers work becaue they are in wrong
thread!! WTF?
// NOPE tv1.setText(" having trouble getting online"); // TODO
// NOPE Toast.makeText(IconicAgain.this, "having trouble getting
online "+ e, Toast.LENGTH_LONG).show();
}
}
};
Can I at least stop this thread somehow? Or close the activity
somehow?

[android-developers] Re: How to force close the app when using multiple activity
The back button will take user to a non-finished activity - normal behavior. The home button should not leave an activity visible, but if you have a non-ui thread still running then that could bring an activity back to view. I kill naughty threads in carefully thought out life cycle methods and cancel thread methods. But if you finish(); an activity when going to the next, then it should not cone back to view unless you start it again with an intent.

[android-developers] Will static variables in a non-activity class remain in memory?
I am storing an ArrayList in a static variable in an ordinary (non
activity) java class.
It works correctly when I load it from an activity, but will it be
guaranteed to remain
in memory even when my activity is not calling it often?
Here is the class:
package com.maps.spoken;
import java.util.ArrayList;
public class NoWordRepeats {
public static ArrayList ar = new ArrayList();
}

Ok thanks for that. The static ArrayList var will certainly be good
enough for what my app requires. I was worried that it might
dissappear between activities by an agressive memory clear up. :)
