That is not an error.
Look at your Java stack trace to find the error. The Java stack trace
can be obtained through adb logcat, DDMS, or the DDMS perspective in
Eclipse.

[android-beginners] Intent-Filter for custom protocols
good morning :)
i have a problem with registring a reciever as i wish :/
My Problem: there exist links like irc://someserver.org/channelXY.
When I try to open them with the browser, i always get some kind of
not found, page maybe moved ...-message.
Now im wondering if its possible to fetch those url-calls to my own
activity. First thought: registering an reciever in the manifest -
like:
receiver android:name=.URIProtocolHandler
intent-filter
action
android:name=android.intent.action.VIEW /
category
android:name=android.intent.category.DEFAULT /
category
android:name=android.intent.category.BROWSABLE/
category
data android:scheme=irc/data
/intent-filter
/receiver
URIProtocolHandler.java:
[...imports]
public class URIProtocolHandler extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent openSoundSettingsActivity = new Intent(context,
ConnectScreen.class);
context.startActivity(openSoundSettingsActivity);
}
}
As far as I understood the concept, this should at least open the
ConnectScreen-Activity.
But - well - nothing happens - the browser is still showing the error
screen.
Maybe someone has an idea and can help me? I seem to be to tired
to get it -.-
Kind regards,
avi

[android-beginners] How do I implement the onClick method for a DialogPreference?
I have implemented onSharedPreferenceChanged in my Preference
Activity, which works for other preference settings but it won't get
triggered when I click on the DialogPreference. I have also tried to
add set the OnPreferenceClickListener to the DialogPreference, which
also works, but this gets triggered as soon as I click on the
preference screen and not on one of the buttons in the actual dialog
window.
I would like to somehow implement the onClick method but don't know
where to do this.
public class Preferences extends PreferenceActivity implements
OnSharedPreferenceChangeListener {
private static final String LOG = test;
private DialogPreference mfactory;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
mfactory = (DialogPreference)findPreference
(pref_factory);
mfactory.setOnPreferenceClickListener(new
DialogPreference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference preference)
{
Log.i(LOG, onPreferenceClick1 entered);
// TODO Auto-generated method stub
return false;
}});
}
@Override
protected void onResume() {
super.onResume();
Log.i(LOG, onResume entered);
// Add a Listener
getPreferenceScreen().getSharedPreferences
().registerOnSharedPreferenceChangeListener(this);
}
@Override
protected void onPause() {
super.onPause();
Log.i(LOG, onPause entered);
// Remove the Listener
getPreferenceScreen().getSharedPreferences
().unregisterOnSharedPreferenceChangeListener(this);
}
public void onSharedPreferenceChanged(SharedPreferences
sharedPreferences, String key) {
Log.i(LOG, onSharedPreferenceChanged entered);
}
}

However when I try to use INSTALL_PACKAGES or BIND_APPWIDGET it does not work. These permissions don't even appear on package installer UI. According to thread http://www.mail-archive.com/android-beginners@googlegroups.com/msg11514.html INSTALL_PACKAGES belong to System Privileges. My question is how can my application get system privileges when working on emulator?

[android-beginners] Key Value pair in a spinner
Hey, I was wondering how to put a string array in a spinner (I can,
using the ArrayAdapter) but I also want to set keys for these also.
But it seems that there's no constructors for that (I may be
mistaken).
I have 2 arrays: {5123, 7434, 7333, 7345 } and {City 1,
City 2, City 3, City 4 }. Obviously, the spinner UI should show
the name array of the cities, but in the backend (what's returned from
the submission of the form is the value.
Anyone knows how?
// Put the array in the spinner
ArrayAdapterString adapter = new ArrayAdapterString(this,
android.R.layout.simple_spinner_item, cityNames);
spinCities.setAdapter(adapter);
While, I'm the subject of spinners: is there any resource on the
internet describing every type of spinner layouts? I'm using
simple_spinner_item but I find it too small. Any suggestions?
Thanks.

[android-beginners] How do I implement onClick for a DialogPreference?
I have a DialogPreference in my Preference Activity and would like to
know which button was pressed. I have implemented the
OnSharedPreferenceChangeListener which does not seem to get triggered
when the DialogPreference is selected. I have also tried
OnPreferenceClickListener but this gets triggered as soon as the
DialogPreference is clicked from the main screen and not when one of
the actual dialog buttons was pressed. was.
So I think I need to implement onClick for this dialog but I am not
sure where to do this.
public class Preferences extends PreferenceActivity implements
OnSharedPreferenceChangeListener {
private static final String LOG = test;
private DialogPreference mfactory;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.preferences);
mfactory = (DialogPreference)findPreference(pref_factory);
mfactory.setOnPreferenceClickListener(new
DialogPreference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference preference)
{
Log.i(LOG, onPreferenceClick1 entered);
// TODO Auto-generated method stub
return false;
}});
}
@Override
protected void onResume() {
super.onResume();
Log.i(LOG, onResume entered);
// Add a Listener
getPreferenceScreen().getSharedPreferences

}
@Override

[android-beginners] Android SDK For Beginners?
Hello, my name is Zack but I go by Azelis. Introduction's out of the way, let's get down to it. From my history of programming, I know that languages based on other languages only make sense if you have extensive background. For example when I started learning NQC for the Mindstorms Invention System it was recommended that I take some C++ tutorials first. However most of these provided me with information I would never need to know (system speciffic stuff). That brings me to where I find myself. Within a week I will be receiving my G1 and I am very interested in programming for it. I have a great amount of programming experience as follows (in chronological order): AppleSoft Integer Basic QBASIC JavaScript Visual Basic Visual C++ TI89 Basic PHP Linden Scripting Language and recently a bit of ASM Basically, with my use of JS and PHP, I am no stranger to the DOM. However I found even the Hello Android tutorial a little difficult to follow, using data types, methods, models, and terms I was unfamiliar with (not to mention that I've never worked with XML, only style sheets). While I was able to kind of understand what was going on, by the time I got to the notepad example I was completely lost. Let me also qualify that I tried learning Java once before to create website applets (yeah, back in those olden days) and most tutorials I found convered very speciffic information that I really didn't need to know. So given my experience with outside tutorials that are only of peripheral interest to me and the knowledge that Android doesn't use the everyday flavor Java VM, is there a Java for Android for Beginners style reference anywhere? Barring that, is there a tutorial/set of tutorials anyone else who was in my position can recommend? Android may very well be the first place solo programmers like myself have a chance to create mainstream popular mobile applications so if such a reference doesn't exist I may well have to spearhead it. - Azelis the White Wolf --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

This works for me for an EditText as well. But when I try the same

In that case, try textEntryView.findViewById(R.id.search_edit).

[android-beginners] Re: Android SDK For Beginners?
Hi Azelis and welcome to Android development! :) I'm pretty much new to programming. Android is my first software development experience aside from some relational database stuff I did years ago. I pretty much had to start learning from scratch several months ago. The first recommendation I have for you is to learn Java. I took this free online course: http://www.javapassion.com/javaintro/ I was new to both java and xml, but I found the xml easier to pick up than the java. Your C++ experience will help you learn the java faster I think. I also read this free Android development PDF book: http://andbook.anddev.org/ Which started to fill in a lot of the blanks for me about Android development. And I purchased the Professional Android Application Development paperback after browsing Android coding books at the local book store (so far it's my fav Android coding book). I still have lots more to learn, but I am on my 3rd or 4th app and I'm really enjoying developing for Android. I also made good use of this group, so I encourage you to also.

[android-beginners] Breaking up Activity classes
As I'm learning about Activities and the components they contain I am wanting to break things up into components. Is there any list of guidelines / commonly used organization of Activity classes? As I add functionality to my apps, things like context menus, options menus, and references to view objects in from resources, my class starts to look really ugly. I have done a lot of .net programming, so at first I wanted to start making partial class declarations in different files but found out java doesn't support this. Are activity classes generally ugly or is there a common way that pro developers compartmentalize things in their activity classes?

Most of the books/tutorials that I have seen assume some level of Java experience. You don't need tons of Java to get going with Android, but you do need to know Java's take on OO (classes, objects, inheritance, polymorphism), popular classes in java.lang/java.io/java.util, etc. Conversely, things you specifically don't need to know include: -- any existing Java UI framework (Swing, SWT, JavaME) or widget libraries for those frameworks (Glazed Lists, etc.) -- any server-side Java frameworks (JavaEE, servlets, etc.) -- JDBC (Android ships with SQLite and has a thin non-JDBC interface to it) -- the enterprise-y frameworks (JAX-this, WS-that, etc.) The API reference (a.k.a., class library) on the Android developer site and in the SDK is the definitive list of what is built into Android and is accessible from your projects: http://developer.android.com/reference/packages.html Barring that, is there a tutorial/set of tutorials anyone else who was in my position can recommend? For Java? Personally, I learned it so long ago that I haven't used much of the current resources. _Head First Java_ is pretty popular in terms of Java books. For Android, there are number of books on the market: http://wiki.andmob.org/books (and, yes, I wrote some of 'em) Tutorials are mostly in blog posts, plus sites like AndroidSnippets.

[android-beginners] Re: Android SDK For Beginners?
I have actually found a resource that is working well for me. It's a book called The Busy Coder's guide to Android. This explains a lot more (although not everything) and I find myself starting to learn how things work. I did go through andbook and found it to be either badly typed or mis-translated and very lacking in explanations and examples (I got the latest version right off the site). Also it ends very abruptly leading me to believe it has not even been proof read yet, let alone finished. Basically, while I am finding the resources and examples I need, I do feel my situation is still fairly common and since my position has often been the guy who stumbles along and then teaches others once he figures it out, I expect I'll be creating or helping to create total beginners' content once I get going.

Greg Hedin wrote:
Are activity classes generally ugly or is there a common way that pro
developers compartmentalize things in their activity classes?
I code in Ruby when I'm not working on Android. All Java code is ugly. ;-)
There are many patterns you can use to help organize an activity. Here
are two that I use, for what that's worth:
1. I sometimes break out the code that binds data to Views for rows in a
ListView into a separate wrapper class, as described here:
http://commonsware.com/Android/excerpt.pdf
2. I tend to break out my listeners and callback objects into private
anonymous inner classes:
private View.OnClickListener onButton=new View.OnClickListener() {
public void onClick(View thingThatWentClick) {
// something almost intelligent here
}
};
(then use button.setOnClickListener(onButton); in onCreate() or something)

[android-beginners] Re: 'if' sentences please help
This is a Java mistake that is common. By common I mean one I make
all the frickin time. You should use String.equals() instead, like
if (!codedate.equals(220809)) {
If you just use the != operator then the JVM will compare the string
pointer addresses, not their values.

[android-beginners] Re: Android SDK For Beginners?
Hmm, I wanted to add that the book I referenced has errors in it. I'm working on the relative alignment section and it references android:layout_toRight when it should be toRightOf. I tried it in both 1.1 and 1.5 to be sure, and I double checked the example. Oh well, pressing on. I did notice in an article elsewhere that it is possible to actually replace the Android main UI, and I've seen videos supposedly of doing this. Are there any guides on doing that? I've set myself a lofty goal for my first complete project. Not that I necessarily feel the need to replace the default UI, I just want to do it so that I know I can do it. Also I'm a fan of Hitchhiker's Guide to the Galaxy. On Fri, Aug 21, 2009 at 5:31 PM, gandor gand...@gmail.com wrote: Zack, By reading your post I realized its not a perfect world.

[android-beginners] Re: how to update a listview
You have to change the data structure that stores the data for the
listView and then call notifyDataSetChange();
Let;s say you are using and ArrayListString lst, you would do
something like this:
public void getRemoteData() {
// .. get data and put it in the array list
adapter.notifyDataSetChange();
}
And, it will update itself.
Hope it made sense and helped :)
