Re: [android-beginners] Play video in resource path
You can refer to video resource as a string and use it for the path.

Re: [android-beginners] Re: Force Close when trying to use getApplication()
I experienced something like this when following the example in the book.
The Author's have code and a comment on this here:
http://unlocking-android.googlecode.com/svn/chapter3/trunk/RestaurantFinder/src/com/msi/manning/restaurant/RestaurantFinderApplication.java
The key to this, I think, is the AndroidManifest.xml file:
http://unlocking-android.googlecode.com/svn/chapter3/trunk/RestaurantFinder/AndroidManifest.xml
application android:icon=@drawable/restaurant_icon
android:label=@string/app_short_name
android:name=RestaurantFinderApplication
android:allowClearUserData=true
android:theme=@android:style/Theme.Black
...
When using this method, you *must* specify the android:name for the
application and it needs to be the name of the application class.
In the specific case described, check AndroidManifest.xml and, if it is not
there, add android:name=BoardGamerFinderApplication

What does logcat say about the cause?

I want to be able to create text views with some tagged text, e.g. iThis text is italic/iband this text is bold/b, and since you can only set one style for all the text in the textview I need to come up with something custom. I've written a class that will parse the string and generate an array of pairs (text paired with style to apply to the text). What I am trying to figure out is how to get a series of TextView objects arranged on the screen such that they wrap around the width of their container. I tried this: LinearLayout xmlns:android= http://schemas.android.com/apk/res/android; android:layout_width=fill_parent android:layout_height=fill_parent android:orientation=horizontal android:id=@+id/TestLayout /LinearLayout And then I tried having my class take a LinearLayout object, and add TextView objects to it, one for each pair (with the styles applied to each individual TextView object). This doesn't work. The content doesn't wrap to a new line when it hits the edge of the screen. So for example for this string: iThis is a long italic string./i and this is normal text band this is bold/b, the output looks like this: This is a long italic string, and this is normal text, a n d t h i s i s b o l d Whereas I would like it to look like this: This is a long italic string, and this is normal text, and this is bold I've tried all kinds of combinations for layout settings to try to get it to work, and haven't had any luck. Does anyone have any advice for how I might get the labels to wrap nicely? I've been thinking that instead I could just use a WebView, and pass it the text to render, but I am worried about the overhead and speed of doing this. These custom labels will appear in a fullscreen ListView with many rows. I'm worried having a webview in each row for a large set would be extremely slow.

Here are some of the things I did. - Removed app from phone using adb: adb uninstall package name - Update these values in Android Manifest file android:versionCode=4 android:versionName=1.02 - Removed an icon in drawable that was not being used - Created APK with same key, but new filename from myapp.apk to myapp3.apk - Updated app in marketplace (upload/update) Someone suggested that I hit this bug: http://code.google.com/p/android/issues/detail?id=830 The bug refers to issues with multiple icons in the manifest file.

[android-beginners] Re: How to pass User created object between two Activity in same Application?
This concept comes from the book* Unlocking Android*.
http://www.manning.com/ableson/
Create an object for your your application that extends the
android.app.Application class
*import android.app.Application;
public class MyApplication extends Application {
...
}
*
Provide access to ClassA in the MyApplication class.
Set and Get ClassA from your activities.
* MyApplication application = (MyApplication) getApplication();
ClassA local=application.getClassA();*
From the FAQ: http://developer.android.com/guide/appendix/faq/framework.html
The android.app.Application class
The android.app.Application is a base class for those who need to maintain
global application state. It can be accessed via getApplication() from any
Activity or Service. It has a couple of life-cycle methods and will be
instantiated by Android automatically if your register it in
AndroidManifest.xml.

[android-beginners] Re: Getting Error package file was not signed correctly using Eclipse ADT
This message comes up when debugger is on: 07-08 10:04:00.873: WARN/PackageInstaller(2957): Parse error when parsing manifest. Discontinuing installation The AndroidManifest.xml has no errors based on review in eclipse. The app runs in emulator. I've tried manually signing app and using jarsigner with same result. I've seen similar issues posted, but no steps to resolution. Any help would be great.

[android-beginners] Re: Using AsyncTask
It took me the better part of 9 pages to explain it with an example in the released-but-not-announced Version 2.1 of _The Busy Coder's Guide to Android Development_. But, it may be I'm just wordy. You can grab the source for that from: http://commonsware.com/Android/ Look for the Threads/Asyncer sample project. The canonical example is on the Android Developers blog: http://android-developers.blogspot.com/2009/05/painless-threading.html Note that the current implementation of AsyncTask limits you to a single background thread. It is fairly easy to pull the source for it into your own project and tinker with the java.util.concurrent objects to add threads, change the queue semantics, etc. -- Mark Murphy (a Commons Guy) Thanks for the example. I'm not surprised it took 9 pages, I don't think this is trivial to understand. I want to understand this better: the current implementation of AsyncTask limits you to a single background thread. Im my case, I've extended a ListActivity. I want to populate the list when it is created and when the user scrolls to the end. I'm using onCreate and onScrollStateChanged. Today I am using a Thread in each of those methods. There is a Handler in the ListActivity class to handle messages from the threads. I can't make the connection on how to do that with an AsyncTask. Is it not a match or am I missing it? Carmen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Simple GridView that displays text in the grids
There is an example in The Busy Coder's Guide to Android Development by
Mark Murphy.
I haven't tried it yet, but preview is online:

i'm following the example on the tutorial about the GridView, but

seems like this is totally unnecessary and it doesn't have a valid use
case, but i'm trying this out to just get myself familiar with the
sdk.
so my code is pretty much the same as the GridView example in
http://developer.android.com/guide/tutorials/views/hello-gridview.html,
but instead of using a ImageAdapter, i created a dummy adapter like
following:
class MyAdapter extends BaseAdapter {
private Context context;
private String[] texts = {aaa, bbb, ccc, ddd, eee,
fff, eee, hhh, iii};
public MyAdapter(Context context) {
this.context = context;
}
public int getCount() {
return 9;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup
parent) {
TextView tv;
if (convertView == null) {
tv = new TextView(context);
tv.setLayoutParams(new GridView.LayoutParams(85, 85));
}
else {
tv = (TextView) convertView;
}
tv.setText(texts[position]);
return tv;
}
it all seems valid to me, but running this gives me nothing on the
screen. there's some selectable/clickable block if i click them, but
the text is obvious not shown. i wonder is my layout doesn't have the
android:text causing this problem? or anything else?
any feedback will be appreciated and thanks for your help!
