[android-developers] Re: how do I add zoom and pan features to my view easily?
that's so half baked as JDK widget,which only provides a UI without action implementation. Idealy there should be default zoom/pan implementation that could be overriden.

[android-developers] HttpURLConnection Timeout does not work
Hi,
I intend to stop a http connection once it times out. Here is my code.
It seems that the setting is not working. Any comments?
-
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestProperty("Connection", "close");
conn.setConnectTimeout(1000 * 10 * 60); // timeout after 10 minutes

Thanks

SharedPreferences preferences = this.getSharedPreferences

You can find the file by running " adb shell"

[android-developers] Re: Can not access to the system properties store?
Thank you for your reply. Do you mean the Settings application is considered to be part of the system? If so, it should be able to change the system properties, right? I am not writing my own application; just modified the original Settings application. I need a system-wide place to store the configured properties and it should be able to be accessed by programs without activity or service context (like method in the Environment class). Could you tell me how to do that? Thanks. On 1月21日, 上午11時28分, Dianne Hackborn wrote: > There are a number of things that settings does that normal apps can't, and > this is probably one of them.

[android-developers] Problem with simpleCursorAdapter, ListView backed by a managed cursor
In a TabActivity I have a tab with a ListView. I manage the visibility of a View for when the list is empty, done after filling the list, whenever I know the backing data changes. When the list is empty (empty View is visible) and the activity is paused, and while paused the backing SQLlite table gets filled, when my activity resumes the ListView gets filled with the new database rows (managed cursor requery?) but I haven't had the chance to set the visibility of the empty View, so it's still there. I can figure out how to do this with some persistent data from pause to resume, but I'm wondering if there's a 'cleaner' and automatic way of achieving this in Android.

[android-developers] G1 Bluetooth stack
I know that T-Mobile's G1 running Android supports multiple bluetooth profiles, however, does the G1 currently support multiple devices to be connected and utilized at the same time? Does/Will the Android SDK support the use of bluetooth devices in this manor or are we bound to many profiles but only one active? Scenario: Both my wife and I have G1 phones, and both are usually found inside the Golla pouches that we purchased but while driving those pouches become quite the bother when you want to know who calls before you answer. So my solution was to think, bracelet/watch & headset combo and now we have the phone still in the pouch and my eyes still on the road. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

"public void characters(char ch[], int start, int length) {

change code to:

[android-developers] Problem with onTouchEvent
I'm trying to intercept onTouchEvent and use the movement to set the number
of seconds on a simple timer. The idea is that if you touch your finger on
the screen and move left or right, up or down the counter will move higher
or lower. My code works but for some reason the increments are not smooth.
Down movements are short and jerky compared to up movements for example. I'm
having a hard time finding any reason for this. My code follows:
@Override
public boolean onTouchEvent(MotionEvent event) {
Message m = new Message();
m.what = timer.GUIUPDATEIDENTIFIER;
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
startX = (int)event.getX();
startY = (int)event.getY();
return true;
case MotionEvent.ACTION_MOVE:
endX = (int)event.getX();
endY = (int)event.getY();
if((endY - startY) < 0) {
this.mySecondsTotal += 1;
} else {
this.mySecondsTotal -= 1;
}
if((endX - startX) < 0) {
this.mySecondsTotal -= 1;
} else {
this.mySecondsTotal += 1;
}
startX = (int)event.getX();
startY = (int)event.getY();
if (this.mySecondsTotal < 0)
this.mySecondsTotal = 0;
DEFAULTSECONDS = this.mySecondsTotal;
this.myYogaViewUpdateHandler.sendMessage(m);
return true;
case MotionEvent.ACTION_UP:
endX = (int)event.getX();
endY = (int)event.getY();
return true;
}
return false;

There are a number of things that settings does that normal apps can't, and this is probably one of them. We generally consider settings to be part of the system, not an application.

[android-developers] Re: android.hardware.Camera - JPEG image of correct size but always black
Oh wait, I completely missed the part where you wrote: "without starting preivew first" You have to start preview first. In theory, you can call takePicture() from the first preview callback, or from the auto-focus callback. In practice, due to a bug in the G1 camera driver, you have to wait for the second preview callback.

I've pasted the output of logcat, trimmed beneath my sig. Unfortunately,
the top of the stack trace reads:

So I'm going to try doing this all over again, more methodically, tomorrow

[android-developers] Can not access to the system properties store?
I am modifying the Settings application, and needing to access the system properties. By using android.os.SystemProperties.get, I can read the system properties. However, I can not set the system properties back with android.os.SystemProperties.set. This function has no return and the system properties never get changed. Why? Is there any permission required?

Forgive the lengthy response. You probably know all of this already and we're just getting hung up on nomenclature... Faber Fedor wrote: > It'd be the top line in the stack trace, after the exception > name/message. > > > Are you talking in DDMS? I can't get threads or the heap working in there. I'm talking about the stack trace. The exception. Use adb logcat, DDMS, Eclipse, I don't care -- it's the place that tells you "this thing went blooey" and shows you all the methods, from the particular line that had the exception up the call stack, where you were at the time. > And while I am ActivityThread.performLaunchActivity, the exception gets > thrown. That is probably the bottom of the stack trace. I'm interested in the top. For example, from http://www.devdaily.com/java/edu/pj/pj010009/pj010009.shtml java.io.FileNotFoundException: fred.txt at java.io.FileInputStream.(FileInputStream.java) at java.io.FileInputStream.(FileInputStream.java) at ExTest.readMyFile(ExTest.java:19) at ExTest.main(ExTest.java:7) In this case, ExText.readMyFile is the line that triggered the exception. However, the exception itself occurred two calls deeper, in the bowels of java.io.FileInputStream's constructor. For many exceptions, this isn't that big of an issue -- you can think of ExText.readMyFile as being "where the exception occurred". For NullPointerException, though, it really helps to know the the line in which the exception was raised -- the first line reported below the exception. Why? Because *that's* the line that attempted to access a null object. So, rolling all the way back to your code, if the first line in the stack trace below the exception is the line you cited (map.getOverlays().add(new SitesOverlay(marker));), then you know that *that line* attempted to use a null object, meaning that either map or map.getOverlays() returns a null. If, however, there are other lines between the exception and the above-quoted statement, that means your code may have *passed in* a null, and so either marker is null or somehow SitesOverlay is having problems and can't be instantiated. -- Mark Murphy (a Commons Guy) http://commonsware.com Android Training in Sweden -- http://www.sotrium.com/training.php --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

Are you talking in DDMS? I can't get threads or the heap working in there. Right before I execute the line, I see my MainMap.onCreate at the top of the stack with Instrumentation.callActivityOnCreate just below it. As soon as I step over it, it looks like my stack has been entirely replaced; at the top of the stack are several calls related to ActivityThread, looks like it's launching a new Activity.

This is odd. I need to make my code pretty, so the first thing I want to do is to change the all the strings 'com.appspot.lbtdl' to 'com.faberfedor.tagyourworld'. I change every string in all the directories using the Perl 'pie' technique. Then I put the code into a new directory, create a new Eclipse project and run it.

Both map and marker have values/content/attributes/whatever you say a non-null object has.

[android-developers] Debugging geolocations services
I wrote some reverse geocoding, geolocation and proximity alert routines for my little Android app.I took my Android out with me when running errands to test my routines; they're kinda hard to test from my couch. Half of them didn't work. What's the best way to debug something like this? Sprinkle a bunch of printf statements (or whatever you call them in Java) throughout the app? Log everything to the sdcard? Write a toggleable view (is that even possible?) that acts as a console?

[android-developers] SurfaceHolder.lockCanvas(dirtyRectangle) bug?
Has anyone ever tried to invalidate a portion of the screen successfully without seeing flickering? I have a portion of the screen (on a SurfaceView) which changes rarely and I don't want to draw this portion if possible because it saves ~16% of all drawing code. So I keep a flag whether I should lock the entire canvas (if this part of the screen is dirty) or a part of it (if it's not). Well, *something* surely happens, but not what I'd expect: 1. The non-dirty part of the screen starts flickering as I stop drawing it. 2. Visually (i.e. I can't prove it by taking a screenshot via Eclipse's DDMS plugin - everything looks fine), it appears that 2 frames are drawn continuously one on top of the other - the current one, and the previous. I appreciate *any* hints, even "don't do it, it doesn't work", so I can concentrate on something more meaningful.

[android-developers] Sensors don't work on partial wake lock
The accelerometer turns off when the screen is off. I'm guessing this is a bug but I haven't seen it logged. Am I missing something? Perhaps the power management features need some improvement - the ability to specify what components are needed during a partial_wake_lock so that power can be conserved as efficiently as possible. BTW, there is a bug logged noting that onSensorChanged() continues to be called for the orientation sensor (during sleep) but the values are not being updated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Long click focus in expandable lists
I have an expandable list with a context menu that can be accessed by long clicking any of the children. The view template used to create the children consists of 2 nested linear layouts with a textView inside the second one. There's more to the GUI than that, but this is sufficient to cause the bug to appear. As long as the groups and children only contain a text field everything works fine. However if I add a button before my textView, long clicks are not received anymore. I can fix this by flagging the inner Linear Layout as LongClickable. The top most one does not need this to work. Doing this allows me to receive longClick events again, however the visual feedback of long clicks (the slow orange to white gradient) is gone. Nothing happens visually when I hold down, however I do eventually receive the event. The weird thing is that the visual feedback still happens fine in focus mode. It's only invisible in touch mode. Does anyone have any idea what I can do to fix this? Here's the xml http://schemas.android.com/apk/res/ android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical" android:longClickable="true" android:focusableInTouchMode="true" android:focusable="true"> --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Animated GIFs (and Marquee) into Android's WebView: a performance question.
Hello. I know there are different people asking this question on the web: "Why are Animated GIFs (and Marquee, and probably also Blink) disabled into the Android WebView?". I digged into the C++ and the Java side: clearly the WebPreferences object that is used to configure the WebView doesn't expose all the C+ + interface, where a method to "enable" the feature is in place. My first reaction is a reasoning: probably there is some performance issues, so they prefer to loose this small thing... Even though I don't really see where a user could run a page with a GIF "so much" to drain the battery and "overtake the CPU", I assumed that the Googlers know better then me. But then I discovered something funny: the Google Apps for Mobile, on startup, they have a "busy animated icon". How they do that? I faked the User-Agent from Firefox and, with the great Firebug, caught the small piece of code that does the trick. It's a "CANVAS". This means that the animation is programmed in Javascript. Ok. Now my question is: isn't this approach of doing the animation worse than doing with an Animated Gif? I mean, I could understand that clearing and re-drawing a small part of the browser buffer repeatedly (with a GIF) can be "cpu-bound" for a mobile device (even thought I do the same thing on S60 device and I never had this impression at all, even with other WebKit based browsers). BUT, that' the question, isn't it even more CPU-bound doing it with Javascript? The redrawing is there anyway. And there is also the computation of the Javascript. With a normal GIF, a lot of optimization in this are made inside the C+ + part: here is all left to Javascript. I hope a Google could answer this question.

[android-developers] Button On Map
Currently I have a MapView and an Itemized overlay which displays different locations on the map. When one of these locations is "tapped" the onTap method creates a new Overlay object which draws an empty speech bubble (the type you would find normally on google maps). What I want to do is then populate this empty speech bubble with some buttons but I am unsure how to do the following: 1) Get a reference to a button from an xml file in the Overlay class ( can't use findViewById() as it isn't an Activity? ). 2) Pin a button so it stays with the speech bubble. Would it be best to create a new layout which contains buttons and place this over the speech bubble?

[android-developers] problem with binding to a service from a BroadcastReceiver
my idea was quite simple, it includes an activity, a BroadcastReceiver, and a local service. i try to bind to the service from either the activity or the BroadcastReceiver. the problem is: if i call binding from the activity, everything looks fine. but, if i call binding from the BroadcastReceiver, it always come back with an exception (security not allowed, smth like that). can anybody help? btw, because this is a loal service, i did not define any permission in the manifest.xml. should i? many thanks CJ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Blocked TextView - URLSpan ...
Hi,
i tried to make a textview with clickable url links. It's blocked, but
only if I
preset the text e.g. like ..android:text="www.google.de".. then the
view
is clickable (on view startup the text will be overwitten by my
program, so
it's invisible):
program.xml:
---
...
program.java:
--
...
private String myUrl = "";
...
public void onCreate(Bundle icicle) {
...
TextView tv = (TextView)findViewById(R.id.urltextview);
String myDisplayString = getTextToDisplay(); //
myDisplayString contains no url
tv.setText( myDisplayString, TextView.BufferType.SPANNABLE );
SpannableString myString = (SpannableString)tv.getText();
myString.setSpan(new URLSpan( myUrl ),
pos1, pos2, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
}
private String getTextToDisplay() {
... myUrl = ""; ...
return displayText;
}
How can I solve this mysterious behavior without presetting the text
value in the layout file ?

[android-developers] How to share classes between different Android projects?
I have two projects that share classes in a third project. Eclipse happily allows me to reference these external classes when I am developing the two dependant projects (as long as the Java Build Path is set up right), but when I try launching the dependant projects, the external classfiles are not copied into the .apk for some reason, so at runtime I get unsatisfied link errors. I don't want to have to maintain multiple copies of the same source file, or even have a copy of these external classfiles in the dependant projects. I also want to avoid adding an extra build step where I build the external classfiles, package them up in a .jar file and include them in the dependant projects. How can I get the Android SDK to simply put a copy of any referenced (non-SDK, non-project) external classes in the .apk at build time? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

I think you may need to remove the @hide directives in the new API's.
I can't help you with the Eclipse plug-in though, I still use VI and

[android-developers] Re: JMI and android
Hi All, Note that it is already possible to create complete apps using JNI. This video ( http://www.youtube.com/watch?v=PYkwHjc6wyo ) shows a Kaleido based ODP (on device portal) running as a Android app without any specific change in the framework itself. Exactly the same app runs fine on ADP, being installed as a regular APK. It's even possible to take advantage of almost all the Android services using BeanShell as a scripting engine from the native code. This is actually what we do on that application that accesses the Android's phonebook for instance. That also means that the same appliaction (excepted its thin porting layer) runs on both the G1 and an iPhone. Franck.
