[android-beginners] Re: Different UI based on orientation
Let's say your layout is in a file called res/layout/myscreen.xml. Simply delete it and instead do the following: res/layout-port/myscreen.xml << for portrait res/layout-land/myscreen.xml << for landscape The system will automatically pick the right one.

[android-beginners] Re: Why won't Intent pass along the extras
Do think to pass a object reference from one screen to another, or from
one activity to another? If implement this using Parcelable, it might be
expensive. What I want is just pass the object reference. But I don't
know how to do it.
Do you have any idea?

[android-beginners] Android design question
The system in place to pass information between the screens... I am
confused why the team chose to reinvent the wheel via the putExtras
methods. Instead of making the transport objects inherit from
Parcelable and the like, why not just use Java's OO strength and set
objects to Activities themselves. For instance, like this:
class Caller extends Activity {
public on buttonClick() {
ThisScreen ts = new ThisScreen();
ts.SetCustomValue(10);
startActivity(ts)
}
}
class ThisScreen extends Activity {
public void onCreate() {
txtBox.setText(Integer.toString(i));
}
public void SetCustomValue (int i) {
...
}
}
Instead we are having to unnecessarily learn new concepts. Was there
a compelling reason to implement it they it's implemented that I am
not seeing?
Thanks.

[android-beginners] Why won't Intent pass along the extras
I have a class object that I want to pass from one screen to another.
So I made it inherit from Parcelable and added the following code to
my class:
public class ItemDescription implements Parcelable {
/// property setters and getters
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
public void writeToParcel(Parcel out, int flags) {
out.writeInt(mData);
}
public static final Parcelable.Creator CREATOR = new
Parcelable.Creator() {
public ItemDescription createFromParcel(Parcel in) {
return new ItemDescription(in);
}
public ItemDescription[] newArray(int size) {
return new ItemDescription[size];
}
};
}
In response to an event, I do kick off another screen (Intent) and put
extras into it:
Intent mIntent = new Intent(v.getContext(), Item.class);
Parcelable itemDesc = getItemDescription(preset); // returns
ItemDescription
mIntent.putExtra("com.vbrad.android.mystapp.item1", itemDesc);
startActivity(mIntent);
In the onCreate event of this new activity, I attempt o retrieve the
contents of the itemDesc object in the following manner:
Intent intent = getIntent();
Parcelable p = intent.getParcelableExtra("com.vbrad.android.
mystapp.item1");
ItemDescription itemDesc = (ItemDescription) p;
However, the itemDesc object is unpopulated - all the internal
variables are at default values (e.g. 0 for numeric types, null for
everything else). It's like it was just created.
What am I missing here?
Thanks.

[android-beginners] Intents and Activities
Accidentally posted this in the wrong area So I'm still working to get the paradigm down. Activities are related to screens and everything you want a user to see needs to be part of an activity. But what's with the Intent? Are all intents tied to an activity? I thought I had read that Intents were more like events. If that's the case cool...but I'm really struggling on where Intents fit into the whole concept. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: Copy File to file system
I am trying to do the same thing but with a database file. And I can
successfully copy a text file to the data directory.
But when I use a sqlite3 db file (either one I pulled off android
emulator data directory or one I made on my desktop machine), I throw
an exception.
Every time I run the read method on a the steam from the db file, I
get an java.io.IOException with no details. Why is this?
I've done some reading and I understand that binary files and unicode
files must be read differently (1 byte versus 2 bites for unicode),
but I thought that readers were for unicode and inputstreams were for
binary. Still, I tried using readers and that didn't work either.
The following code works perfectly to copy a file named textfile.txt
from my raw resource folder. However, when I switch the text file for
an actual myapp.db file (even if I try using the same name as the text
file), I get an exception. If I comment out the while loop, the error
goes away. And it's the read that has the problem. If I comment out
just the write line, I still throw an excpetion.
Is there something different about this file type that won't allow me
to read a stream from it as I am doing?
private void copyDataBase() throws IOException{
//Path to the just created empty db, which I carefully closed so I
have safe write access
OutputStream databaseOutputStream = new FileOutputStream("/data/
data/com.mydomain.myapp/databases/myapp.db");
InputStream databaseInputStream =
databaseOpenHelperContext.getResources().openRawResource
(R.raw.textfile);
byte[] buffer = new byte[1];
int length;
while ( (length = databaseInputStream.read(buffer)) > 0 ) {
databaseOutputStream.write(buffer);
Log.w("Bytes: ", ((Integer)length).toString());
Log.w("value", buffer.toString());
}
//Close the streams
databaseOutputStream.flush();
databaseOutputStream.close();
databaseInputStream.close();
}

[android-beginners] Re: Checking Internet Connection
You might also try and be careful. It seems that many applications on many hand-held devices, if they are attempting to have a persistent connection with anything such as GPS or internet will drain a battery fast. I realize these devices are getting better at handling such demanding applications but just something to keep in mind. Possibly look for a way to have retrieve information from the internet/GPS when you know it is needed.

[android-beginners] Intercepting web browser clicks
Hi All, I have an interesting problem: I'd like to create a background service that can somehow detect/intercept/keep track of user clicks on the phone's internet browser. I was wondering if this is even possible. I know you can overwrite your own WebView to get this information, but given that the phone's browser and my service are completely different applications, I doubt that the service can get any information about the browser's clicks. If you're wondering why I want to do this, it's because I'm doing a research project at school.

[android-beginners] Different UI based on orientation
Not sure if this is been answered (I searched). I am working on an app that should have a different look depending on the orientation (i.e. if the keyboard is opened). Specifically, certain buttons I put in the UI should disappear when the keyboard is opened, since the keyboard will be used for that. How can this be done in the code?

If you are not familiar with Java, you probably should learn that first outside the Android environment. There are numerous Java educational resources, from free online tutorials to books like _Head First Java_. To learn Android, there is a tutorial or two on the Android site (http://code.google.com/android/). Beyond that, there are numerous tutorials published on various blogs, at least five books, and so on.

[android-beginners] Synchronized Statements In Lunar Lander Sample
Hi everyone! I'm new to both the SDK and Java in general (coming from a Flash dev background), and I had a quick question regarding the Lunar Lander sample code: I was just wondering why synchronized statements are used in all of the methods in the LunarThread when it's the only thread ever in use in the activity. Looking solely at the code for the Lunar Lander game, it doesn't look like you'd need intrinsic locks. I'm following all of the examples and the (well laid out) documentation on the SDK fairly well, but the sychronization in that thread has me confused. As a novice, it looks like it's unecessary to me, and I was hoping someone could clarify why it's been done.

[android-beginners] Fetching and Storing Images
Greetings, I am trying to fetch and cache a number of thumbnail images - about 80 - to the device.

[android-beginners] How to save and restore database
Hi, Can anyone please tell me how to save existing database to sd card and then later read from that file ? Here's what I want. I have created an application which writes to the db (sqlite) as and when the user enters data through a form page. I want to make an option to save existing database to a file on sd card, so that the user can do a restore from that saved database file. Once the user has saved the database the data persists even after the application has been uninstalled from the device, so that after he re- installs the application the old database is persistent and he can restore data from that file. I do not want to read and write to it every time the user saves new data. I want it do save or restore on user demand. I have not worked with files yet, so I do not have any clue as to how it can be done. I would really help me if someone can give me some pointers or a sample application which does the same.

Use transactions. The heap problem is probably due to SQLite holding everything in transaction buffers. You might, say, do a transaction for every 100 entries or so. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 2.0 Published! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

If you want the .apk, you should download the SDK and abide to its end-user license, which as far as I know forbids reverse engineering and redistributions of certain proprietary binaries (which the Google Maps application is probably part of). The SDK will allow you to develop applications that use the Google Maps API, some people also use it to run the application on real hardware too. If you're interested in distributing the application in one of your products, you should contact someone else at Google, since I can't help you and this is a forum for people developing Android applications. > It will be of great help for me if anyone can share me the .apk file of > google maps application. > > > Thanks, > Ramakrishna. > > On Tue, Mar 10, 2009 at 1:01 AM, David Turner wrote: > >> the applications are pre-installed in the read-only /system partition.the >> Google Maps source code is not available. the corresponding .apk should be >> somewhere under / though. >> >> >> On Mon, Mar 9, 2009 at 6:35 PM, Ramakrishna > > wrote: >> >>> >>> Hi everybody, >>> >>> I just wanna know how Android emulator manages to install >>> all the applications by default when it is started.
