[android-developers] Re: Serial Port Programming
I did this for an early protoype that hooked Android up to an actual GPS device. You can do this by creating a separate process using that reads from the COM port and then communicates COM port info to Android over HTTP or directly over sockets. If you need to init the device or send AT commands, you can create two way communication between Android and this process. Most recently I used C# since the .NET framework on Windows has good support for COM ports. A number of years ago I used an open source Java library for similar work but was unable to locate the project when I last looked a few months ago.

The value 0 is for a null or invalid resource. All other integers are valid resource values.

[android-developers] Re: Listview and List Selector(Urgent)
For your first question, I think you can just create a layout with whatever views you need for a list item (perhaps just a single textview) and then add padding to that. Here's an example: ?xml version=1.0 encoding=utf-8? TextView xmlns:android=http://schemas.android.com/apk/res/android; android:id=@android:id/text android:layout_width=fill_parent android:layout_height=wrap_content android:paddingBottom=20sp /TextView Then just reference that as a the list item to use when you set the list adapter. As for the second question, there might be a way to do this with styles, but I don't know right now. You could programmatically do it by setting an OnItemClickListener for the list and then just make a setTextColor call on the TextView. Probably in your instance, the View that gets passed into onItemClick is the TextView.

[android-developers] Re: How notification for inserts and deletes works without ContentProvider
You could solve this by sending a bundle with the id of the newly created item to your listactivity and focus the list on this item when it recieves the bundle from the subactivity. The delete thing could also be solved in a similair way, but I agree that it would be better if this worked automatically. On Apr 7, 4:55 am, vl [EMAIL PROTECTED] wrote: I don't know what error you are talking about. If you create a listactivity and use a correctly implemented contentprovider (for example the Contacts content provider) the data in the list will updated automatically when records are added, deleted or changed. The error is related to notion of a selected item. Take NotesList demo application (Note pad) as an example. 1) Create few notes. 2) Navigate through the list using up/down keys. You can see that selected item is highlighted. 3) Click Enter. You'll see edit view. Do editing and exit it. The item you just worked with is still highlighted (but may be in a different position in the list). 4) Now execute delete operation. ERROR: There is no highlighted item, but if you press Enter - one of the items will be selected, so according to Android there is a selection. 5) Add a new item. ERROR: When control is returned from the editor, new item is not shown as highlighted. For applications with small number of items in a list it would not be a big problem, but for cases with big lists (someone on this site mentioned that list activities were designed for tens of thousands of items) it could be a very serious issue. List views are refreshed in my application too and I am not using content provider. Originally I thought that absence of content provider was the reason for incorrect behavior in respect to highlighted list items, but this is not the case. I still do not know how this problem could be resolved. I cannot find in Android appropriate notification mechanism between activities to support what I see as the important requirement. So from this point I have not found any advantage of using ContentProvider for my application. And support of joins in content providers is still a mystery for me (see one of the previous notes in this thread). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Annotations and reflection
Are reflection methods like
java.lang.reflect.AccessibleObject.isAnnotationPresent() implemented?
Here is my example:
-- i have this simple annotation:
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface GSTestAnn {
}
-- i have this class:
public class GSTest {
@GSTestAnn
public void annotated() {
// empty
}
}
-- and finally this block of code:
GSTest test = new GSTest();
for (Method m : test.getClass().getMethods()) {
if (m.isAnnotationPresent(GSTestAnn.class)) {
log(is in : + m.getName()); }
else {
log(NOT in : + m.getName());
}
}
If i run this example outside Android, everything works and name of
method annotated() is prefixed by is in in log. But if I run it
inside Android, all methods (including annotated()) are prefixed
with NOT in .. does it mean that it isn't implemented? (it's same
for other reflection methods as well)
Thanks for any advice,

[android-developers] Invalidate() on child view does not work.
This is my problem. I have a main view, a TableLayout view, this view has other views as its children added to it. One of the child views is a custom view, MyView, that I created to draw graphics on it and to receive click events. The other children are all buttons. When I click on the MyView the MyView.invalidate() button is called so that MyView gets refreshed with the new graphics. What is supposed to happen after calling invalidate() is that the MyView.onDraw() method is supposed to be called but it is never called. After some experimenting I discovered that the only reliable way to get MyView.onDraw() to be called is for me to call the top view's invalidate() method, in this case the TableLayout view. Anybody has seen this problem before and know how to fix it. Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

But, the reason you don't see logging output is the way you are using
Log. You are actually trying to print an empty message (the second

[android-developers] Re: Content Provider and notifying changes
Hmm it seems i have missed some stuff, there is: public final void registerContentObserver(Uri uri, boolean notifyForDescendents, ContentObserver observer) where notifyForDescendants specifies if this observer receives notifications for its descendant uris.

Hi there everyone, I'm just gettin' warm with Android and after years without writing a single line in Java I had a hard time today when I tried to figure out how one could establish communication via a serial port with Android.

[android-developers] Re: Is it safe to share a View among several layouts?
Thanks hackbod, for replying. As a well wisher, I must say the slowness of the Android UI really bothers me. It took 17 seconds to parse an XML file and load the UI widgets - a list of compound items. The same list loaded almost instantaneously - too fast to measure by hand, but less than half a second - using a Java Swing application. The parsing and loading code was identical - except that in Android one has to use the SAXParserFactory class, and in Swing, I could use XMLReaderFactory directly.

[android-developers] Re: Listview animation problem
Hi, This is because ListView caches its children in Bitmaps during a scroll to get better performance. You can try turning off the caching (see the documentation for XML attributes in ViewGroup and AbsListView). On Mon, Apr 7, 2008 at 7:05 AM, wonderoid [EMAIL PROTECTED] wrote: I have some custom animated icons in a listview. These items are animated by calling invalidate() on their onDraw() method (Just assume a simple animation, like setting a different background color on every draw). Now when i scroll the listview using keys all is fine; however when i scroll it with the mouse; icons stop animating and not even explicitly calling invalidate on them starts the animation again. Any ideas?

import java.lang.annotation.Target;

}
If i run this example outside Android, everything works and name of
method annotated() is prefixed by is in in log. But if I run it
inside Android, all methods (including annotated()) are prefixed
with NOT in .. does it mean that it isn't implemented? (it's same
for other reflection methods as well)

[android-developers] Confusing Problem about VideoView
The VideoView example works fine when play just a sigle mp4 file, But
I wander if I can pause the current playing file and setpath to
another file ? I tried but it failed.
how should I do if I want to switch between different mp4 files while
the previous one is not finished?
I use the following code to set a new file to a videoview:
if (mVideoView.isPlaying()) {
mVideoView.pause();
mVideoView.stopPlayback();
}
mVideoView.setVideoPath(X.mp4);
mVideoView.setMediaController(mMediaController);
Is there anything wrong?
The result is the first runing file paused, and the second file can
not run. when switch back to the previous one, it crashed
(BTW, the videoview widget seems resource consuming, It can't work on
my old T42 notebook with 1G memory, 1.7G cpu 1core, the application
die often, but on T61 with 2 core CPU, it works just as expected...)

The parsing and loading code was identical - except that in Android one has to use the SAXParserFactory class, and in Swing, I could use XMLReaderFactory directly. You really need to understand: what you are running when your app is in the emulator, is an EMULATED versions of the ENTIRE operating system. That is, the only native x86 code that is being run is an ARM CPU emulator and the UI shell of the emulator. The ARM emulator is, in turn, running a complete ARM-based system, from the Linux kernel, up through libc, to the Dalkvik interpreter itself. Yes, your Java code is being emulated twice: first by the ARM emulator running the Dalvik code, then the Dalkvik code running your and the system's Java code. And that ARM emulator is emulating a big chunk of the ARM hardware, including things like the MMU. Posting things about how the Android emulator is running slower than some native Java code is simply not useful to anyone, because you are comparing apples to oranges. They are not the same thing at all. As Romain says, we can assure you that on actual hardware the system is running with reasonable performance keeping in mind that the performance is not going to be anything like running Java on your desktop, because the hardware is significantly less powerful. So the basic question is: is your application's UI running more slowly than other parts of the UI that are included with android? If so, then like I said there is some issue in your application or how it is using the platform, which can probably be significantly narrowed down if not discovered through the profiler. If you are just generally complaining about the overall performance, then a solution you might want to consider is to get a faster desktop machine. (Though there have been some known performance issues when running the emulator on at least certain windows machines. I'm not sure what the state of those issues is.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Escaping values in SQL Queries
Hi all When using the SQLite functions in the Android API is there a way to escape special character in a string before using it in a query? I am a little worried about forming queries using code such as ... FIELD=\ + value + \ ... in case the value contains special characters. Not escaping values properly can result in SQL Injection Vulnerabilities is data is from untrusted sources, and we certainly would not want that! Does the whereArgs in the update method call get escaped automatically? Does this apply to Strings passed to ConentValues as well?

[android-developers] dynmatically create menuitem
Hi There, As you know, we create a menuitem at onCreateOptionsMenu method, However, when the view content has been changed, for example, first the Screen is blank, no view is added,and we display only one menuitem called Add a Button, After fullfill this function, I want to add a menuitem Delete a Button when A button-view added to screen and focus is on. so when the user click menu, it will show Add a Button,Delete aButton. How to implement this function, which method should we override it? Thanks~~ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

I've built some Maven plugins to build with Android. http://code.google.com/p/masa/ I don't use Eclipse either. Just type 'mvn install' and it will build the app and install into the emulator. In the trunk version, there is also an option for deploying directly to a JVending server http://code.google.com/p/masa/, which you can use for testing OTA delivery.

[android-developers] Is there a way to set the minimum size of a window?
So many questions lately... I've got a WebView inside of a Window (using the dialog theme). It works fine as long as the website is loaded quickly. In that case, the WebView resizes the window just correcly. But it seems that if it takes a while to load the page, the WebView forgets to resize the window. So I'd like to at least set the minimum size of the window as a workaround.

[android-developers] Re: Are you satisfied or disappointed with the level of support from Google, for Android?
That's important for the Android team and for the Open Handset Alliance and its members, that's important for Google. That's also important for the developer community and for the end users. Hello Jean-Baptiste, I suggest that the aim be for the phones to come out in 2009. If everyone is patient, then that will be a proof of cooperation. The Android Team doesn't needs phones for 2008. Neither does the OHA. And there can be more Developer Challenges. More Developer Challenges would appear to be important in two ways. To perfect Android and also for Google promotion. ATT seeks to depart more away from Google apps which is reasonable for them. However, Google has the Cloud and that Cloud can come out in creative ways through a couple more Developer Challenges. At the risk of being melodramatic, Android is the most important piece of software in human history. I really don't think it should be rushed. Everyone should be patient and that Patience will pay off. - Juan On Mar 29, 12:28 pm, Jean-Baptiste Queru [EMAIL PROTECTED] wrote: (Notice: I'm a Google Software Engineer working on Android). One aspect which I hope is reasonably clear in everybody's minds is that getting devices available is really at the top of the priority list for everyone involved in Android. That's important for the Android team and for the Open Handset Alliance and its members, that's important for Google. That's also important for the developer community and for the end users. From that point of view, every day that passes without devices out there hurts the entire Android ecosystem, and therefore has a high cost. Because of that, whenever anyone has to choose between doing something that directly helps ship those first devices and something that doesn't directly help, the latter option has to carry a very high value in order to outweigh for the cost of delaying the first devices. That's why the SDK isn't as polished as it could be, that's why Google employees aren't as present on those forums as they could be: it would distract from the primary goal of shipping devices in 2008. It might sound surprising to many, but Google only has a finite number of people who are currently familiar enough with Android to be able to make a significant difference on either the ship date or the SDK and the developer community. It takes time and it takes money to grow a team, Google has a significant amount of money but remains careful about how they spend it like any well-managed company, and they can't do anything about time: even by having people work hard, there's always a limit to how much work any single person can achieve every day. All that explains why you're not seeing dozens of engineers spending several hours every day answering questions and helping people on the forums, or preparing a new SDK every other week: at the end of the timeline toward the first devices, that would result in delays that would be counted in weeks or even months. Having to choose is painful, because we'd all like to get the best of both worlds. You can't have your (proverbial) cake and eat it too, and right now we're a bitstuck between a (proverbial) rock and a (proverbial) hard place. Back to the issue of the SDK, I think that you've put the finger on one of one of the aspects that are hard to balance: how early and how often should it be released. Too early, and developers get some software that is too unstable and too far from the final product to be valuable. Not early enough, and developers don't have time to get familiar with it, provide valuable feedback and have applications ready for the first device. Too often, and developers will spend too much time chasing porting their code from one release to another and the whole ecosystem will be confused about what works and what doesn't in every release. Not often enough, and some developers will bestuckfor weeks on bugs that may have been fixed but be unavailable. And, like I said earlier, early and often have a negative impact on the ship date. During the software development cycle of a framework, you're likely to see 3 phases: bringup, unstable, and stabilization. During the bringup phase, the software improves quickly, but it is too rough and too far from its final shape to be valuable to many people - this is a phase that typically sees frequent releases to a very small number of close partners. During the unstable phase, the framework is large enough and is used by enough applications that it can't change quite as quickly as during the bringup, but it is still getting some very significant changes. This is the phase during which the release strategy changes from frequent limited releases to infrequent broad releases. This is the phase that M3 and M5 came from (as an example, you've all seen how the UI had changed between M3 and M5). Finally, there's a stabilization phase, where the framework gets fewer and fewer changes and gets closer and

[android-developers] Re: Listview and List Selector(Urgent)
thanks Dan i have done it like this
mText.setTextColor(new ColorStateList(
new int[][] {
new int[] { android.R.attr.state_selected},
new int[1],
}, new int[]
{
Color.rgb(255, 255, 255),
Color.BLACK,
}
));
but there is a problem i want to show a white background border on
selecting a listview item ..how can i do this ??
On Apr 7, 11:36 am, Dan U. [EMAIL PROTECTED] wrote:
For your first question, I think you can just create a layout with
whatever views you need for a list item (perhaps just a single
textview) and then add padding to that. Here's an example:
?xml version=1.0 encoding=utf-8?
TextView xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@android:id/text android:layout_width=fill_parent
android:layout_height=wrap_content android:paddingBottom=20sp
/TextView
Then just reference that as a the list item to use when you set the
list adapter.
As for the second question, there might be a way to do this with
styles, but I don't know right now. You could programmatically do it
by setting an OnItemClickListener for the list and then just make a
setTextColor call on the TextView. Probably in your instance, the View
that gets passed into onItemClick is the TextView.

[android-developers] Change ListView Item height?
Hi, Can anyone show me how I would go about changing the height of the items in a ListView? Also is there a way to pad the actual text list? I want to put a background and make the text (and more importantly the divider ) not as wide as the background. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] View Activity Communicaton
I have been programming for android since January, and I must say, that I still don't get how the communication between Views and Activities is accomplished successfully. The whole design on this communication is fuzzy at least for me. NOTE: using M3 currenlty. Examples: Activities can have menus, creating when onCreateOptionsMenu( Menu menu ) is called Later we can get the menu selection by implementing onOptionsItemSelected( Menu.Item item ). So, inside and Activity, we have access to user actions/input in the form of a menu, and hence we can react to it, for example, by launching another activity (typical usage). This works, because we are in the context of the activity. NOTE: This is what I'm using now, so that I could keep on developing until I find a solution to my problem (next). Now if, you look at the View object, it's the only one to have user input handlers, like: onMotionEvent( MotionEvent event ) ( or onTouchEvent for M5), and onKeyDown( int keyCode, KeyEvent event ) ! An Activity doesn't have those ! So, how can we handle user input, and react accordingly ? If we call intent.startActivity() from within a View , we get an Application Error, with the following description: An error has occurred in process XXX calling startActivity() from outside of an Activity context requires the NEW_TASK_LAUNCH flag. is this really what you want ? The explanation, stating that a flag is required is fine ! But how am I to know the answer to the question ? (is this really what you want ?) http://code.google.com/android/reference/android/content/Intent.html#NEW_TASK_LAUNCH If I force the Flag, I will enter into further configuration problems or limitations, due to how we MUST setup the Activity launchMode (http://code.google.com/android/reference/android/ R.attr.html#launchMode) Which means, that I will have several simultaneous tasks for every menu option, which is not what was wanted. I can possibly set my lauchMode to singleTask, but is this really what I want ? I'm just trying to do a simple common thing, react to user input by launching a specific sub activity of the application, like in a menu kind of way. I know that there is the concept of subActivity in M5, that probably helps (not sure though), but this should be easy to do, even in M3 and apparently it's not ! Either I'm missing something, or I haven't still got it, how this is supposed to work. And having Documentation only for M5 stuff, doesn't help much either. Enlightnment on this subject and the View/Activity communcation/user input duality would be real nice. I needed this to work to finish my Contest entry! :( Or else I have to keep using the general Menu, instead of my game Menu, which doesn't quite cut it for a game application. NOTE: I'm trying NOT to break the rest of my app, by Porting the remaining stuff to M5. I have an early version that I had ported to M5, but I went back due to some stuff not working on M5, so not really an option. I also don't expect a new SDK Release now so close to the contest deadline, which could fix a lot of things, but could also bring a whole lot of new bugs too. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Any generic logic for intent identification to be used by existing applications
Hi! Is there a way in android to extend the intent identification logic for existing applications. Say for example i type in the rss feed url or an http url in the phone application or something similar. So can I extend the identification logic such that the application executes a parser defined by my code, and then depending upon the identified intent fires the activity which handles the intent.

[android-developers] Re: bitmap image changed. but why?
You are doing something really strange!
First you setup a bitmao as your canvas
bitmap = Bitmap.createBitmap(100, 100, true);
Canvas canvas = new Canvas(bitmap);
But later, you use your canvas ( which uses your bitmap as it's
buffer) and you draw on it, using itself, i.e. you feedback the same
bitmap
canvas.drawBitmap(bitmap, 10, 10, null);
This is shure to fail, since the copy behaviour is not defined how it
should behave in case you are copying it to itself.
Use different bitmaps, one for canvas, and another for whatever you
are drawing.
TIP: if you set thePixels(...) of your bitmap (buffer) you don't need
to draw those same pixels after, since they are already there !

These code just retrieve the pixel data and then put them back. But
why i got different result on the screen. It seems like the retrieve
method change some pixel? Can anybody help me with this please?
Thanks.

[android-developers] Re: View Activity Communicaton
Another Example: How do we call our activity finish method, from our activity view class ? Inside an Activity context, we can just call finish(); Inside a view, apparently we can't get a reference to the Activity that contains us (the view), and even if there is a way to get the reference, we can't probably call it directly, due to UI threading issues. So, do we send a message ? How ? How do we get the reference to the Handler defined inside our Activity, to be able to call myHandler.sendMessage(...) ? I think the UI handling code is complex and cumbersome to work with. I agree that probably should use messaging, since this helps to decouple the several application parts, but the current API, is not very helpful, in making the common message usage simple. Any help on this would be great too.
