Just use startActivity(), possibly with the NEW_TASK flag. You can look at the home screen sample code in the SDK for an example.

[android-developers] Re: written file not found
Probably, that is because they cannot browse /data due to security restrictions.

They are in the same spot on the device as they are in the emulator. You just cannot browse to them. However, you can use adb pull to download them. I thought that the adb pull is a tool for eclipse and the emulator. how can i use that on the g1?

Access is granted while installing. You may choose to go through the list of things accessed and stop installing. I don't think there is any other level of app specific access control available at present. Settings work in a global context. So, say once the GPS is enabled (through settings or other apps), any installed app could use it (if the app was granted permission to while installing). I too would love to see some such firewall kind of stuff in future but this will need core changes and can't be a simple security / gateway / firewall app. Cheers, Rajesh.S On Mar 26, 5:36 am, trust_chen chen trustc...@gmail.com wrote: how to prevent the special application of android to access the network? thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Android Projects Promotion Pages Online
*Yeah. Recently in China there have been many web pages for Android, even if not yet a single Android phone is officially released in China. The problem is, the domestic Android software industry is quite legged behind. It can not be imagined that Android would have the chance in China if the apps couldn't catch up. The good thing is, there are already or would be many apps in the global basis, particularly from the western countries like the U.S.A, the birth place of Android. Therefore, it is quite natural for us wonder how a bridge can be built between the supply and demand ... Obviously, the official Android Market is not doing good enough, here I mean, in that only English language is presented. Even, the developers have spare little attention for the East. It can be speculated that so far most of the apps are only in English. ... Maybe I am over-worrying ... By the way, the pages of Android software promotion http://www.aidiji.comwere updated and totally English-friendly. *2009/3/23 mercury xu xumerc...@gmail.com Hi Gollum Of course, there are lots of people pay more attention for this OS in China,and pay lots of time for develop and desinge much more softwares,not only at application programs but also OS Device drivers,such as me.haha~~also,in china, there are lots of websites for android's fans to communication and discussion ,such as www.androidin.com , www.android123.com,of course, my website www.51wince.com.

The pages are mainly targeted at the market of China, which as you know, has the population of billions. Here, your product would have the audience on the billion scales, especially when in the near future (it is April as claimed) China Mobile, the dominant mobile operator within China, will launche the Android campaign with substantial Android phone products from many manufacturers.

[android-developers] Re: Anything on Android that can do smooth scrolling?
I've also proposed a solution to this - adding a permission for apps to request that they run alone, uninterrupted by other processes. That is, the app can request a permission, demanding that the app can only be interrupted by an external event, such as phone call, all other services and background processes (other than the ones the OS can't go without) are paused when app is running. I know it's quite tricky to implement this, because, for example, when an SMS is received it needs to be stored in the database, and this will require some memory, which will need to be discarded, when the SMS is written to the database, and this will trigger GC. However, when such a message is received, and the OS knows that an app with the special permission runs in the foreground, it could delay the GC either until: - the app itself allocates memory (no matter if it might not be actually GC'ed until the app finishes) OR - the systems goes pretty low on memory At least, non-stock services (i.e. services, developed by 3rd parties) can be suspended during the lifetime of an application requesting the special permission.

Thanks for the responses guys. My question was more like how come its smooth in the picture viewer app despite running multi processes? Its the only 2d app I've found that does this correctly, but its reassuring to know it DOES work. Surface views seem good for static surfaces with moving objects on top, but bad for scrolling objects. Checking the picture viewer code again, I think they are using an oversided view with scrollto methods. I will try this later to see if this works better.

[android-developers] Decoupling localization and translation
Hi, I ran into a problem with the way Android resolves resource paths. Apparently the folders below are invalid: res/values-rAT res/values-rDE res/values-rGB What I am trying to do is decouple the localization of my application (mostly just urls to web-services i use) from the translation (mostly user interface strings), thus allowing a user to select locals like: de-rGB or en-rAT without actually creating all those synthetic folders. Right now I have 3 languages and 6 locales so it is still manageable, but as the number of languages and locales increase the number of directories will explode out of control. So I was wondering: 1. If anyone knows a workaround for this? A placeholder language code that resolves to any - something like res/values-xx-rAT? Or any other way around? 2. Is this a bug? Will those directories be supported in the near future? thanks for reading this far :), gesh. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: photo picker Uri issue
cheers, did not know that about Drawables will use Bitmaps then.
Thanks,

On Mar 25, 3:23 pm, Streets Of Boston flyingdutc...@gmail.com wrote:
This Uri is the logical (not physical) path used by the image content
provider.
If you want to get the physical path to the actual file on the SD-
card, query this Uri:
Cursor cursor = query(photoUri, new String[]
{MediaStore.Images.ImageColumns.DATA}, null, null, null);
String absoluteFilePath = cursor.getString(0);
Now, absoluteFilePath is the physical path to your image, which you
can use in Drawable.createFromPath
Question: Why don't you create a Bitmap instead?
...
InputStream is = getContentResolver().openInputStream(photoUri);
Bitmap bm = BitmapFactory.decodeStream(is);
...
is.close();
I ask this, because it is safer to cache Bitmaps instead of Drawables.
If you cache Drawables, you run the risk of memory leaks. Drawables
have handles to your activity and when your activity gets destroyed
while your Drawables are still cached, your activiy will never be
garbage collected -- memory leak.
Bitmaps don't have this problem. They are basically byte-arrays with
some behavior :).

Let me explain what I'm talking about: There's a myFaves service on the G1. Apparently it tries to send an MMS once, or once in a while to T-Mobile. Because my G1 is unlocked and running on a different network, the MMS transmission fails. However, myFaves won't give up and will try sending the MMS. When I got my unlocked G1 December last year, it had the 1.0 firmware. Perhaps the myFaves service was running very very rarely because I've never seen my game stutter, even though many background processes were in fact running. That is, perhaps I was testing the game on the device when myFaves was not trying to send the MMS. When the OTA updated the firmware to 1.1, the myFaves service started to attempt to send an MMS to T-Mobile more often. This triggers GC for exactly 110 objects and N bytes of memory, and my game stutters *every* time the myFaves service is attempting to send an MMS (apparently, it will *always* try sending the god damn MMS because I'm not on T-Mobile's network). So, my point is not that background processes per se are the problem, but these who actually perform any work which might trigger GC.

[android-developers] File size column in image database is always 0 for the newest image
Hi,
I am uploading images to our webservice from the phone, and thus I
need to know the exact size of an image. I noticed that with some
photos from the G1, the webservice always failed, and found out that
it's due to the file size always being 0 for the latest image in the
database.
Is this a known bug? What else can I do to find out the size of an
image on the phone without going through the DB? I want to avoid
writing the whole image to a byte buffer just to find out its size...
here is some code to play with:
ContentResolver contentResolver = getContentResolver
();
Cursor c = contentResolver.query(
Uri.parse(content://media/external/images/
media),
new String[] { Images.ImageColumns._ID,
Images.ImageColumns.DISPLAY_NAME,
Images.ImageColumns.SIZE }, null,
null, null);
while (c.moveToNext()) {
Log.d(PHOTO, c.getLong(0) + + c.getString(1)
+
+ c.getLong(2));
}
c.close();
This gives me 0 in the third column for the last entry (that's the
newest photo).

[android-developers] Re: Providing text-to-speech (TTS) capability in my Android application?
If you need more languages, voices, I think a client/server solution would be better. Android app send a request (POST) to a TTS web server. The server sends back a mp3, or a html page with a link to a mp3. You download the mp3 on the SD card, and play it. The problem : finding a FREE TTS server online At least there a some free demo, you can start your dev. with them (ATT, vozme, VoiceForge...).

[android-developers] Re: File size column in image database is always 0 for the newest image
I had the same problem and it was driving me nuts. I think it's a bug.
Below is how i worked-around it.
Do what you do now by calling insertImage(...).
This will insert the image into the data-base; however, thumbnails are
not correctly generated and the SIZE attribute is 0 (your problem that
you see).
Execute a query, and use the cursor to get the physical file-path (use
the ImageColumns.DATA).
Using the physical file-path, use the MediaScanner
(MediaScannerConnection) to scan your newly inserted image.
After the MediaScanner has finished, querying your image on
ImageColumns.SIZE (and other attributes) should work correctly.
I suggest to do this in a seperate worker-thread... it is kinda-slow.

Hi,
try the 'setHeader(String name, String value)' method from the HttpGet
class. For example:

DefaultHttpClient client = new DefaultHttpClient();
HttpGet method = new HttpGet(url);
HttpResponse response = null;
method.setHeader(user-agent, getText(R.string.app_name).toString());

}
catch(IOException e) {

Using setHeader replaces the first header with the same name or if not

[android-developers] Re: Anything on Android that can do smooth scrolling?
There are some problems with that approach: -it's an arms race. You've already identified the need for certain apps to continue running even when there's an exclusive app running, which'd have to be protected by a permission. Either that permission is system-only and we move further away from the goal of having all applications equal, and it's accessible to all applications and it's only a matter of time before all applications have it, which makes the entire exercise pointless (put yourselves in the shoes of the developer of an app with background components - from their point of view, their app is obviously the most important app, and they don't want anyone to be able to tell them that their app isn't allowed to run). -the granularity that you really want is not that of an application - preventing other applications from running will prevent their services and providers from running even if they are necessary to run the front application. -even if you could do that, it would only be a partial solution at best, as system_server itself will probably still do a few allocations, and binder transactions eventually cause GCs as well. FWIW, this would be an excellent discussion for the android-framework group, where we discuss how changes in the android platform impact SDK-level application development.

Now, I realize that this permission should not be that simple - it should allow the apps to specify which components are OK to run (system components will always run, of course). For example, the RSS reader application will want to run itself, and this or that service it depends on. I don't see how this would be a problem. The permission should simply allow one or more components to be listed as dependencies. -even if you could do that, it would only be a partial solution at best, as system_server itself will probably still do a few allocations, and binder transactions eventually cause GCs as well. Processes, which absolutely need to run (performing or not GCs) is OK to run. Think about it - the experience will in *any* case be greater, than it is now.

[android-developers] Re: Building user interfaces at runtime with layouts from server
I chose the do it yourself approach and parse the layout.xml by
myself. The simple part (reading the element names and building the
widget tree) works quite well. Then I wrote an own implementation of
android.util.AttributeSet which wraps a org.w3c.dom.NamedNodeMap. When
I try to instantiate a View class with my own AttributeSet
implementation I get hit by a ClassCastException. After a short
investigation I found the following code.
When can I expect this to be fixed?
android.content.res.Resources.Theme
public TypedArray obtainStyledAttributes(AttributeSet set,
int[] attrs, int defStyleAttr, int defStyleRes) {
int len = attrs.length;
TypedArray array = getCachedStyledAttributes(len);
// XXX note that for now we only work with compiled XML
files.
// To support generic XML files we will need to manually
parse
// out the attributes from the XML file (applying type
information
// contained in the resources and such).
XmlBlock.Parser parser = (XmlBlock.Parser)set;
--- NOT GOOD FOR MY OWN AttributeSet implementation
AssetManager.applyStyle(
mTheme, defStyleAttr, defStyleRes,
parser != null ? parser.mParseState : 0, attrs,
array.mData, array.mIndices);
array.mRsrcs = attrs;

Thanks for your response. My use case is as follows:
We have a server application which allows to be extended by plugins.
Each plugin contributes a view and some logic. Until now, the only
client we support is a web client. Every plugin contributes a jsf
based xhtml page plus some java beans.
What we want to do now is to support a native android client. A part
of its user interface should be fixed, another part should be provided
by the mentioned plugins. By adding a new plugin on the server, the
user should be able use the new functionality immediately. To make
that working, a plugin needs to provide a kind of an android user
interface description. And of course, the android client needs to be
able to render this user interface description, register generic
listeners on the given ui and handle events appropriately (by sending
a response to a web service for instance).
The point is now: Android already has this user interface description
(layout.xml) and the code which inflates such a description (in
preprocessed form) to a user interface. It would be awesome to reuse
this code!

Hi all,
Q: What is the recommended way to build user interfaces on the device

I am aware of this:
snip source=http://developer.android.com/reference/android/view/
LayoutInflater.html
For performance reasons, view inflation relies heavily on pre-
processing of XML files that is done at build time. Therefore, it is
not currently possible to use LayoutInflater with an XmlPullParser
over a plain XML file at runtime; it only works with an XmlPullParser
returned from a compiled resource (R.something file.)
/snip
I could imagine these possibilities:
- Parse XML by myself and build the ui tree. (Seems inappropriate to
me since there is already maintained code which is able to do this.)
- Transform XML on server to a simpler format which is cheaper to
parse on the device. (Inappropriate as above.)
- Preprocess the XML layout on the server the same way the build does.
Transmit it to the client, and then try to load it. But how?
android.content.res.XMLBlock is hidden (@hide) and I don't know how
to
classify the stuff in package com.android.layoutlib.bridge.
Any help would be appreciated.

It might turn out to also be more acceptable design-wise, and easier to implement in the framework.

[android-developers] Re: Anything on Android that can do smooth scrolling?
Got to say I'd prefer a good user experience to developer orientated features any day. All apps can be still be created equal, all that needs to happen is alongside the exclusive running permission there is an interrupt everything permission that allows an intent to pause an exclusive running app to interact with the user (e.g. message arrived popup, etc). The exclusive app can use the onPause and onStart part of it's lifecycle to handle the interruption.

The permission should simply allow one or more components to be listed as dependencies. It's not as simple as it seems, as you're putting a requirement on background applications to identify which components they (transitively) rely on in order to work properly. Imagine that your app relies on component A, but that (as an implementation detail) component A relies on component B: now you need component A to identify that it needs component B, so that component B can also be made immune to the kill-by-game behavior. Actually I don't need to specify anything. I just proposed that. I now realize you can do it automatically. The second an app marked with the special permission binds to a service or accesses a content provider, it is more than obvious that the service, is indeed needed by the application and should be allowed to run.

[android-developers] Re: Anything on Android that can do smooth scrolling?
The problem with your reasoning is that it's far from obvious that your hypothetical user will clearly understand that launching your game will prevent their other apps from running (there's plenty of evidence that users don't understand the consequences of their actions as well as developers do). Of course, you'd like them to only care about your game, but you can't assume that this will be the case for everyone (and the situation gets worse if your game is really good and they spend a long time playing it). Please file a feature request for the no-GC feature so that we don't forget about it. how is it possible for other apps to trigger GC in my process? The system asks every relevant process to GC at different points in time, especially when it's running low on memory. That's not its only tool - it can also flush caches or kill processes when that's appropriate. Is Android so aggressive about launching as few processes as possible, that it won't run my app in a new process, even if the # of running proceses is low? As a developer, you have control over the way the components in your apps get spread into processes. If I remember correctly, you can split an app over multiple processes, and you can have components from different apps running in the same process. Even without caring about that level of control, you can still be sure that your apps' components won't run in the same process as app components from other developers, since that'd break the entire security model. Android currently does keep processes around when it has enough memory for it - there's a cost/benefit tradeoff, since an empty process takes space, but having it around saves a lot of time if it can be re-used to re-launch an application in it.

[android-developers] Re: Anything on Android that can do smooth scrolling?
I've already said this once -- even though your game can be tuned to the max, nothing prevents *other* apps from triggering GC. That is, in my game, I *never*, *ever* do any allocation after startup. However, other background processes do trigger GC, and voila - my game stutters for a bit when GC kicks in. Other apps CANNOT cause GC in your process. Background processes can interrupt your game but it has nothing to do with GC. -- Romain Guy Android framework engineer romain...@android.com Note: please don't send private questions to me, as I don't have time to provide private support.

[android-developers] Re: Task activity stack always reset when launched from Home
The code that starts the .About activity is:
protected void startAbout()
{
Intent aIntent = new Intent(this, About.class);
startActivity(aIntent);
}
The Manifest entries for .UserLaunch and .About are in my original
post.
The intent that returns the task to the front is generated by the
Launcher.
What flags do I need to set (and where) to prevent this from
happening? Is one of the default values causing it?
My test case here is:
1) launch .UserLaunch from the launcher
2) start .About
3) hit Home key
4) launch .UserLuanch from the launcher
There are no long delays in any of this, so the 30 minute auto-clear
should not be invoked.

I am just starting on an Android app and I am puzzled about why my
Task activity stack is being reset any time the application is
launched from the Home screen.
I used the ADT tools to create the application in Eclipse.
The main activity is .UserLaunch and it starts the activity .About
when the user presses a button.
If the user then presses HOME and then relaunches the app, .UserLaunch
is displayed and is the only thing on the stack.
.UserLaunch has the launchMode singleTask. .About is standard.
According to the documentation at
http://developer.android.com/guide/topics/fundamentals.html#lmodes:
However, a singleTask activity may or may not have other
activities above it in the stack. If it does, it is not in position to
handle the intent, and the intent is dropped. (Even though the intent
is dropped, its arrival would have caused the task to come to the
foreground, where it would remain.)
The Task stack should be brought to the foreground and .About should
still be displayed.
I added Logging to all of the lifecycle events (edited to remove
timestamps and shorten DEBUG/ and INFO/ to D/ and I/) and you can see
that when HOME is pressed, .About cycles through onPause and onStop
(as expected). Then when the app is again launched, .About is
destroyed and .UserLaunch is restarted

In addition to the points he raises, it sure would be nice if my Google ID could be associated with the apps I've pulled down to my phone, and maybe even select apps to push to it -- or maybe set up favorites I could then page to on the phone and download from there. I guess I'm saying the web interface is bad but the phone interface isn't that great either. I'm setting up my second G1 after setting up my wife's about a week ago, and finding those must have apps out of the huge list of other apps is pretty time consuming and frustrating.

[android-developers] When save image, how to specify image name?
I have the following code to save a bitmap to a jpg file. It works except I
couldn't specify the file name.
The image file is save in /sdcard/dcim/Camera. How do I specify a file name,
or even the saved path?
Cheers
ContentValues values = new ContentValues();
values.put(MediaStore.Images.ImageColumns.DISPLAY_ NAME, newpic);
values.put(MediaStore.Images.ImageColumns.MIME_TYP E, image/jpeg);
Uri uri = getContentResolver().insert(MediaStore.Images.Medi
a.EXTERNAL_CONTENT_URI, values);

[android-developers] RingtoneManager.ACTION_RINGTONE_PICKER
Hello. I tried to post earlier and my browser was acting funky. I
don't see the post, so I am adding another. I apologize if both show
up.
I am using Android SDK 1.1_r1. I want a user to be able to open the
ringtone picker, select a ringtone, it the OK button and have the
result sent back to the parent activity. When I start the ringtone
picker as a sub-activity, it appears to call setResult() immediately.
I could be way off and just not understand how this works. Here is the
code that I am using to lauch the sub-activity:
mPickRingTone.setOnClickListener(new View.OnClickListener()
{
public void onClick( View v )
{
ringMe.startRingPick();
}
});
private void startRingPick()
{
Intent i = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
startActivityForResult(i, ACTIVITY_SET_RINGTONE);
}
@Override
protected void onActivityResult( int requestCode, int resultCode,
Intent data )
{
switch( requestCode )
{
case ACTIVITY_SET_RINGTONE:
Log.d(toString(), ACTIVITY_SET_RINGTONE DONE);
// this method takes the data
getToneToRing(data);
}
super.onActivityResult(requestCode, resultCode, data);
}
When I press the button the ringtone picker dialog opens and
immediately I see ACTIVITY_SET_RINGTONE DONE via LogCat. This is on
a physical device.
Do I not understand something?

[android-developers] Routing UDP data to the emulator
I've been scouring the forums and found similar issues like this, but
the solutions seems not to be working.
What we're doing is trying to receive data from an external server via
UDP. At the moment, doing a tcpdump on linux provides information that
yes, there is data coming into my computer. From here, however, things
become murky.
I have tried the following two tactics:
telnet localhost 5554
redir add udp:5000:5000
where 5000 is the port on my computer that is receiving data and 5000
is the port where Android is listening to. This achieves nothing.
The other tactic is the adb forward, which has the same results.
The UDP Server code is as follows:
public class Server extends Thread {
private InetAddress serverAddr;
private DatagramSocket socket;
private static int port = 5000;
private static final String tag = UDP Server;
public Server() {
try {
this.serverAddr = InetAddress.getByName(10.0.2.15);
this.socket = new DatagramSocket(port, this.serverAddr);
Log.d(tag, listening port 5000);
} catch (Exception e) {
Log.d(tag, Failed accessing server address and
socket);
}
}
public void start() {
super.start();
}
public void run() {
Looper.prepare();
while(true) {
try {
byte[] buf = new byte[43];
/* Prepare a UDP-Packet that can
* contain the data we want to receive */
DatagramPacket packet = new DatagramPacket(buf,
buf.length);
this.socket.receive(packet); // Receive the
UDP-Packet
Log.d(tag, Received: ' + new
String(packet.getData()) + ');
} catch (IOException e) {
Log.e(tag, Error, e);
}
}
}
}
What this should do is listen to Android's network/ethernet interface
and output the recieved data (if there is any). What I get is nothing.
Android does not say that there is an error in Logcat or that anything
is received. This seems to tell me that the information is not being
redirected properly to the emulator.
Any thoughts on getting this redirection business settled?

[android-developers] Wireless voice over IP
Hi, I would like to know the best way to go about building a wireless voice over solution for the android platform? I know the question might be too general, but I would like to details such as which voice over IP server to use. In addition to this would it be possible to encrypt and decrypt packets before transmitting in order to make it secure? Would this affect the call clarity.

[android-developers] RingtoneManager.ACTION_RINGTONE_PICKER
Hello. I am trying to allow someone to choose a ringtone and to get
the URI or order number of this and pass it back to the parent
Activity. Maybe I am going about this the wrong way. The problem that
I am having is startActivityForResult() launches the ringtone picker
but immediately
call setResult(). However the ringtone picker seems to work fine, i
just cannot capture the value of the picked tone(that part of the code
is not here because it never gets that far).
Here is how I am trying to do this:
calling it from a listener:
mPickRingTone.setOnClickListener(new View.OnClickListener()
{
public void onClick( View v )
{
startRingPick();
}
});
private void startRingPick()
{
Intent i = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
startActivityForResult(i, ACTIVITY_SET_RINGTONE);
}
@Override
protected void onActivityResult( int requestCode, int resultCode,
Intent data )
{
switch( requestCode )
{
case ACTIVITY_SET_RINGTONE:
Log.d(toString(), ACTIVITY_SET_RINGTONE = +
ACTIVITY_SET_RINGTONE);
}
super.onActivityResult(requestCode, resultCode, data);
}
