Re: [android-developers] Re: Where in code would i resize an image taken using intent?
Daniel,
In my case, the large image is read from storage resized then saved to
storage.

[android-developers] Re: Choreographer regularly skipping frames during OpenGL Render
Thanks for the response, Doug, but we're talking about two different
things. I'm not referring to the errors that show up the log tagged
Choreographer when the frame warning limit is triggered on the main thread.
I'm talking about actually using the Choreographer API to render OpenGL
content locked to VSYNC. These delays are on the rendering threads. While
I understand frames dropping periodically when the system is servicing
other work, the inability to manage even a few second without skipping
several VSYNC intervals indicates to me that something else is wrong with
the GL code.
Thanks again,

Bear in mind that anything could be causing main thread delays. It could

multitasking multiuser operating systems and the wide variety of devices

The Choreographer itself doesn't start complaining about skipped frames in
logcat until after 30 frames have been skipped:
private static final int SKIPPED_FRAME_WARNING_LIMIT =
SystemProperties.getInt(
debug.choreographer.skipwarning, 30);
So maybe you can lighten up your own acceptable threshold for frames
skipped (unless you're actually observing the jank that you're trying to
avoid)?

from Choreographer to do the rendering.
For simplicity sake, I have basically copied the Basic Dream application

Our only change is that, where they call mSquare.draw() inside of

glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
} else {

However, for the purposes of this discussion, you can see the *exact
same behavior* by simply running the AOSP sample as an application (i.e.
changing the Colors class from a DreamService to a launcher Activity).
The problem is that on a regular basis (at least once per second, often
many times), the debug logging returns that the frame callback took 33ms
(instead of 16ms), and in many cases 50ms+! I can understand skipping a
rare frame here or there, but skipping 3-4 frames at once seems like I'm
missing something big here. Not all devices do this, but high-end devices
like the Nexus 5 and GS4 do. Devices we've tested like the Note 3, GS3,
and Moto X don't seem to do so nearly as often. Example typical logcat

Re: [android-developers] Using ACTION_OPEN_DOCUMENT for editing files
Thanks for the thoughts, Jeff. I understand your reasoning, so perhaps the best course of action is to modify the example documentation. The Edit a document section of the SAF Guide (https://developer.android.com/guide/topics/providers/document-provider.html#edit) states that to edit a text document in place, the correct choice is ACTION_OPEN_DOCUMENT. Based on what you are saying, since ACTION_CREATE_DOCUMENT allows you to pick an existing file, that is the better choice for in place editing. The guide should probably either be changed to reflect ACTION_CREATE_DOCUMENT for editing, or to indicate that using ACTION_OPEN_DOCUMENT should include a branch check on FLAG_SUPPORTS_WRITE to determine if the edit can happen in place, or if ACTION_CREATE_DOCUMENT will need to be used anyway to create a new file for the edit changes.

[android-developers] Using ACTION_OPEN_DOCUMENT for editing files
As far as I can tell from the documentation and testing with the new Storage Access Framework and Intent.ACTION_OPEN_DOCUMENT, there doesn't seem to be a way (via an extra or otherwise) to pass with the Intent request to open a document to only return documents from providers that support writing (i.e. have FLAG_SUPPORTS_WRITE set). Instead, we are forced to check a document selection made by the user (via a metadata query) to determine if the document supports write before we attempt to open an OutputStream or ParcelFileDescriptor in w mode. Is this correct, or have I overlooked something? This seems to be a large missing piece in the new Storage Access Framework when attempting to allow a user to open an existing document to be edited as it forces the user to make a selection first, then have us check if they can write, throw and error if they cannot, and force them to pick again. Furthermore, we cannot say that it is uncommon for documents providers not to support writing, because even the system media documents provider (i.e. the source for images/videos) does not support write and will throw and IllegalArgumentException (Media is read-only) when one attempts to write to one of its files (as an image editing app, the most common example used in the docs, would attempt to do). Is there a proper method with the new SAF of limiting selections to writable providers only? Feedback appreciated for anything I may have missed here. As it stands, suggesting that developers use ACTION_OPEN_DOCUMENT for in-place editing doesn't seem like a viable approach.

[android-developers] Re: Deep sleep after 1 hour?
Does the app do anything else other than ping the server? Best way to approach this really would be to set an alarm which fires every 30 seconds, when you receive the alarm take a partial wakelock and fire a service to perform the ping, this service should also take and release a wakelock whilst performing the ping.

[android-developers] Re: Cannot get the initial SDK setup working, nightmare
Using the AVD tool (inside Eclipse, menu Window - Android Virtual Device Manager), create at least one virtual device. See http://developer.android.com/tools/devices/index.html After you have a virtual device created, start it by selecting it in the list (in AVD manager) then click the Start button. Note: depending on your computer, it may take a while for the emulator to start. After you see the emulator window and the android virtual device is fully booted, click around to see how it works (it is slightly different than a real device). With the emulator running, right click on your android project and select Run as - Android application. You may be asked to select a device (pick the AVD you just created).

Re: [android-developers] Efficient Tablet Resource Selection
Hey Mark - Apologies, I misspoke on the newer devices. That part of the equation does work as expected for 3.2+ devices since smalles width is a higher priority selector. You make a valid point about older devices with a single qualifier and how eliminating just flags the device didn't understand rather than the whole directory would make the resources look like default resources in that case, and cause overlap in others. It makes sense why it doesn't work the way I had hoped. The larger problem this creates is becoming more notable as higher resolution, larger screen phones become available. The biggest issue with the 5 directory solution I posted above is that it allows newer handset devices that understand they are smaller than 600dp, but are physically large enough to report large will now drop into the wrong bucket (i.e the upcoming Droid DNA). The hope was that by combining the two into a single directory we could reduce code duplication and close those loopholes, but I'm not sure a solution exists here. Perhaps the only true is answer is two APKs on each side of the division line. Or maybe eliminating large as an option...if it's pre-3.2 and not a 10 tablet perhaps it deserves to run the same UI as the handset... If only there was a market qualifier to mask out specific versions so we could support 2.2 - 4.1 with a single APK, just excluding 3.0 and 3.1 ;p Dare to dream...

You can demonstrate this by taking a vanilla project, renaming res/layout/ to res/layout-swNNNdp/ (for some likely value of NNN), and running it on an old emulator.

[android-developers] Efficient Tablet Resource Selection
I am trying to develop an efficient method of including resource qualifiers to appropriately select the layouts (and other resources really) for handsets, small tablets, and large tablets. To properly support devices on both sides of Android 3.2, when smallest width was introduced, I had hoped to be able to create a hierarchy like so: res/layout/ + Default and handset-specific layouts res/layout-sw600dp-large/ + Small Tablet assets, where necessary res/layout-sw720dp-xlarge/ + Large Tablet assets, where necessary However, constructing a simple test application in this manner reveals that the concept won't work. All devices load the default resources, regardless of their OS version and display configuration. The primary point of this method is to eliminate the duplication that would otherwise be required to place the sw600dp asset and large asset (which are the same) into separate directories. Even aliasing a single layout into the two directories represents a duplication of code. To support older devices, it would be nice to continue to use just the old qualifiers, but newer handset devices with larger screens are starting to creep into the large category, forcing the use of smallest width where available. So my first question here is: I know my original idea does not work, but I want to know WHY it doesn't work?? In my mind, the old devices that don't understand the sw qualifier should just ignore its existence and the two directories should just look like large and xlarge. On the other side, with new devices, the sw qualifier should take precedence so the large and xlarge should become irrelevant. As a result, the method with the least code duplication that I can come up with is as follows: res/layout/ + All layout assets, with tablet specific names in cases where necessary res/values-sw600dp/ + Aliases to apply small tablet layouts with the default name res/values-large/ + Same aliases to apply small tablet layouts with the default name res/values-sw720dp/ + Aliases to apply large tablet layouts with the default name res/values-xlarge/ + Same aliases to apply large tablet layouts with the default name This reduces the duplication to at least one line in two places rather than copying an entire file. Does anyone know of a method that works that would clean this up even further? Thanks, -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Messenger from Remote Service Causing Memory Leak
I have an application that communicates with a Service in a remote process
using the Messengerinterface. Here is the basic architecture of how things
are set up:
- The application generates several Operation objects that require
access to the service.
- Each Operation contains a Handler wrapped in a Messenger used as a
callback receive the response data back from the Service
- When the operation executes, it wraps its Messenger into an Intent and
calls startService() to pass the message to the remote service
- The remote service does some work based on the parameters of the Intent
and
then returns the response by sending a Message to the Messenger for that
operation.
Here is the basic code present in the operation:
public class SessionOperation {
/* ... */
public void runOperation() {
Intent serviceIntent = new Intent(SERVICE_ACTION);
/* Add some other extras specific to each operation */
serviceIntent.putExtra(Intent.EXTRA_EMAIL, replyMessenger);
context.startService(serviceIntent);
}
private Handler mAckHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
//Process the service's response
}
};
protected Messenger replyMessenger = new Messenger(mAckHandler);
}
And a basic snippet of how the service is structured:
public class WorkService extends Service {
private ServiceHandler mServiceHandler;
private final class ServiceHandler extends Handler {
public ServiceHandler(Looper looper) {
super(looper);
}
@Override
public void handleMessage(Message msg) {
onHandleIntent((Intent)msg.obj);
}
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
//If intent has a message, queue it up
Message msg = mServiceHandler.obtainMessage();
msg.obj = intent;
mServiceHandler.sendMessage(msg);
return START_STICKY;
}
private void onHandleIntent(Intent intent) {
Messenger replyTarget = intent.getParcelableExtra(Intent.EXTRA_EMAIL);
/* Do some work */
Message delivery = Message.obtain(...);
replyTarget.send(delivery);
}
}
This all works fantastically well. I can send tons of operations from
several different applications to the same service and they all process and
send their response to just the right place. However...
I noticed that if the application ran long enough and with enough activity
it would crash with anOutOfMemoryError. Upon looking at the HPROF data in
MAT, I noticed that all these operations where staying in memory, and they
were held hostage from the Garbage Collector because of theMessenger.
Apparently, the Messenger instance is creating a long-term native
connection to Binder that counts as a GC Root, which is keeping each
Operation object in memory indefinitely.
[image: MAT Trace Example]
Does anyone know if there is a way to clear or disable the Messenger when
the Operation is over so it doesn't create this memory leak?
Is there perhaps a better way to implement the IPC to the Servicein the
same fashion, so that multiple disparate objects can make a request and get
a result asynchronously? I'm not convinced that just switching to using a
bound service implementation will solve this issue as I would will need the
Messenger to process the callback.

Re: [android-developers] Messenger from Remote Service Causing Memory Leak
Dianne - Thanks so much for the insight! That seems very much to be the case because if I force a GC through DDMS on the remote process, all those objects in the application process finally get released. Something else I would recommend is to not do a design where you instantiate Messenger objects for each IPC you do. Create one Messenger that you pass in to each IPC call. Otherwise you can generate a lot of remoted objects that are being kept around due to other processes continuing to hold references because the other side is not aggressively garbage collecting since all the objects it is creating due to these calls are small. Your point is well taken about the design issue; this statement looks to describe my application exactly. The service has so few objects it rarely ever triggers GC, but it is in control of all the other objects in my application process. I will take a look at this and the workaround you proposed as well. Thanks again! Dave Smith @devunwired On Thursday, August 30, 2012 4:12:02 PM UTC-6, Dianne Hackborn wrote: It is true that sending a messenger across processes will require holding a GREF on it for the other process to communicate with it. Barring bugs (which have happened but I am not sure if in any released platform versions), the GREF will be released when the other process itself no longer holds a reference on this. When we are talking about things in Dalvik no longer holds a reference generally means the other side has garbage collected the Java proxy object. What this means is that when you throw a Messenger (or any IBinder object) across to another process, the Dalvik VM in your own process can no longer manage the memory of that object itself and is dependent on all remote objects releasing it until it can be released locally. And this will include all objects that the IBinder has any references to as well. A common pattern to deal with this is to use a WeakReference in your IBinder/Messenger that holds the references to the rest of your objects that it will access. This allows your local garbage collector to clean up all of those other objects (which may be quite heavy, holding big things like bitmaps and such) even though a remote process still has a reference on your IBinder. Of course if you do this, there needs to be something else holding a reference on these other objects until they are no longer needed, or else the garbage collector could clean them up *before* they are no longer needed. Something else I would recommend is to not do a design where you instantiate Messenger objects for each IPC you do. Create one Messenger that you pass in to each IPC call. Otherwise you can generate a lot of remoted objects that are being kept around due to other processes continuing to hold references because the other side is not aggressively garbage collecting since all the objects it is creating due to these calls are small. -- Dianne Hackborn Android framework engineer hac...@android.com javascript: Note: please don't send private questions to me, as I don't have time to provide private support, and so won't reply to such e-mails.

Hi!
I started Android development last week, and I have a problem with a code
on some devices :
I have to develop an application with a specific controller like a
horizontal wheel. To do this, I want to use the ViewPager, with
setClipChildren(false) to extend the view. I based on the following code :
https://gist.github.com/8cbe094bb7a783e37ad1
The result looks like this :
https://lh4.googleusercontent.com/-DjFOnG7O0wY/UDstWN3AE2I/AfE/yWpndOBTWIA/s1600/emulator.png
The ViewPager here is just on Item4, and with setClipChildren(false) we
can see the other item.
This works greats on emulator (tested on API 7 to 16) and some devices!
But I encounter some problems on more recent devices, like HTC One X
(Android 4.0.4) and a Nexus S (CM10 - Android 4.1.1) : the ViewPager
doesn't really extended! Just the current item is shown, and when you are
sliding, the next item is shown :
https://lh3.googleusercontent.com/-clS7voj3rLk/UDsvfP1HnhI/AfM/K8uMV_9PLFA/s1600/onex_current.png
When sliding :
https://lh5.googleusercontent.com/-3tYaKu_Oz7w/UDsvnljXJ0I/AfU/JEaCZolThJ4/s1600/onex_sliding.png
Anybody else already encounter this problem? I think is an optimization on
these devices, but how can I bypass this?
Thanks in advance!

[android-developers] ADB and Mountain Lion Issues
I noticed that, as soon as I upgraded to Mac OS Mountain Lion (10.8) I have been unable to reliably get any of my devices to connect with ADB (Galaxy Nexus, Nexus S, HTC EVO 4G, just to name a few). It can take upwards of 10-15 cable re-plugs, re-starts of the ADB server, and toggling USB Debugging on the device before it finally shows up. I attempted to load the Android File Transfer Application (http://www.android.com/filetransfer/) thinking it might have something to do with the lack of MTP support on Mac OS, but that did not seem to change anything. There are no further updates to SDK beyond 20.0.1 that I can see which might address the issue either.

Re: [android-developers] Re: Renderscript Deprecated
To add a little more context to the deprecation notice (I think the choice of the word experimental is a little misleading, sorry for the confusion): The feedback we got from internal and external app developers was that they preferred to use OpenGL directly because of familiarity portability either through our Java bindings or NDK. In contrast, we do see interest in the compute API of Renderscript. Hence we've decided to no longer evolve the RS graphics APIs (hence deprecation notice) and instead focus on building out Renderscript's GPU-compute support and developing Renderscript further especially for applications such as image processing.

[android-developers] Using searchview in ActionBar can't save state between rotation because onCreateOptionsMenu called twice
Has anyone seen this behavior in ICS? What's happening is if a fragment is participating in the options menu for an activity both the activity's and fragments onCreateOptionsMenu is being called twice when the phone is rotated but only once when the activity is initially started. (See my linked stackoverflow.com question below for complete code and output) The bigger problem is that if a fragment adds a SearchView to the options menu, the SearchView can't remember it's state when the phone is rotated. It's no longer has any text in the textview after the rotation. If the activity uses a searchview, the state is saved correctly when rotated. I've seen this on the emulator running ICS 4.0 (API 14) and 4.0.3 (API 15) and also Verizon Galaxy Nexus running 4.0.4 build IMM76K. I can't figure out what's causing the onCreateOptionsMenu to be called twice. It doesn't make sense that this would be the normal way to create the options menu when rotating the phone. Maybe I'm doing something wrong to cause this? or I need to handle the onCreateOptionsMenu differently when the phone state is changed. Here's my question on stack overflow. This is complete with example code and log output of what I'm seeing. http://stackoverflow.com/questions/11003941/android-oncreateoptionsmenu-called-twice-when-restoring-state#comment14380762_11003941 Thanks ahead of time for any help. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Is there a way to change GridView zigzag direction and enforce column or row move?
http://developer.android.com/reference/android/widget/GridView.html
The default way the elements of the array is put in a GridView is
zigzagging left-right-down.
e.g. array {1,2,3,4,5,6,7,8,9,10} becomes
by default (with columns fixed to 3)
1,2,3
4,5,6
7,8,9
10
Is there a way to get to zigzag up-down-right (with rows fixed to 3)?
1,4,7,10
2,5,8
3,6,9
Also I like to be able to enforce a column move in getView. Free
zigzag style: No fixed number of columns columns or rows:
For instance in free up-down-right zigzag
1,5,6,9
2, 7,10
3, 8
4
In free left-right-down zigzag
1,2
3
4,5,6,7
8,9,10
And then in getView with a command tell the GridView to go to the next
column or row.
I now kind of solved it with row and column data in a database table,
sort it in a query and inserting dummy elements to the array to get
the right layout, but I wonder if there is a more direct and efficient
way to this. The database is also larger and filled with presentation
data which is undesirable.
e.g. in free up-down-right zigzag
I have 10 domain data elements but with inserting 6 dummy elements the
array size is increased to 16.
It would be more efficient to keep the array size 10.
Or are there alternative views which do this job better?

Change your adapter to serve out the items in that order. Or, rewrite
GridView. Note that your example shows a mismatch of columns (4 in
first row, 3 in others), which GridView does not support, except for
the last row.
Also I like to be able to enforce a column move in getView. Free

Write your own AdapterView.
If you do not need selection events and your roster of items is small
enough (100), the new GridLayout in Android 4.0, wrapped in a
ScrollView, can probably handle what you need. I think I saw a
backport of GridLayout for earlier versions of Android floating around
GitHub.

Hi, I have installed the android sdk 16 on my Windows7 machine I have installed the Android2.1 API initially without any glitch. But then again when I try to install the other APIs using the SDK manager, it gives me: Downloading SDK Platform Android 2.3.3, API 10, revision 2 File not found: C:\Program Files (x86)\Android\android-sdk\temp \android-2.3.3_r02-linux.zip (Access is denied) Downloading Samples for SDK API 10, revision 1 File not found: C:\Program Files (x86)\Android\android-sdk\temp \samples-2.3.3_r01-linux.zip (Access is denied) Skipping 'Google APIs by Google Inc., Android API 10, revision 2'; it depends on 'SDK Platform Android 2.3.3, API 10, revision 2' which was not installed.

[android-developers] ViewRoot and the repaint process
I'd like to get pixel access to the Bitmap to be able to transmit graphics over the wire. It seems this could be possible via the Canvas Bitmap. But since ViewRoot is final I'm not sure where I can intercept this information in the drawing process. Is there an appropriate spot in the rendering processes where I can grab pixels from the Bitmap for the current View Tree?

[android-developers] problem of using intent to start activity of an add-on package
Hi,
I am using an add-on in my app.
When I try to start an activity defined in the add-on package, it
complains ActivityNotFoundException:
in my code:
package com.a.c.demo.search;
import com.a.b.SearchActivity;
import com.a.c.demo.R;
public class ActivityDemo extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Button btn = (Button)
findViewById(R.id.launch_search_activity);
btn.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent();
i.setClassName(com.a.b, com.a.b.SearchActivity);
i.putExtra(KEY_SEARCH_HINT_TEXT, Search);
ActivityDemo.this.startActivityForResult(i,

}
});
}

category

/intent-filter
/activity
activity android:name=com.a.b.SearchActivity /
the add-on is in the java build path.
When I ran the app, I got error from log cat:
ActivityNotFoundException:

I don't know java more than enough to put lines of code together from examples. I just wish Google had a setting that automatically did clustering of markers with same lat lng for us. And the next thing I am trying to figure out how to do: have a html list of the marker place names in one TD where the text hyperlinks to the marker and opens its infowindow.

[android-developers] Fragments duplicated on config change
I'm encountering a peculiar issue with the user of FragmentActivity. In my test app, my FragmentActivity's onCreate method calls setContentView, which inflates a simple layout consisting of a single Fragment. However, I'm finding that when the device is rotated, this process causes additional Fragments to be created, such that after one rotation there are two Fragment instances, and after two rotations there are three Fragment instances being created. I'm also unclear why, when this Activity is first launched, the Fragment instance created via setContentView() appears to be started, stopped, and then started again. Below is a logcat demonstrating the issue (hashCodes in brackets). Should fragments simply not be inflated via setContentView? *** App launched *** 05-22 17:39:13.044: VERBOSE/DupeFrag(10519): TestActivity(1080185976).onStart() 05-22 17:39:13.044: VERBOSE/DupeFrag(10519): TestFragment(1080196160).onStart() 05-22 17:39:13.044: VERBOSE/DupeFrag(10519): TestFragment(1080196160).onStop() 05-22 17:39:13.044: VERBOSE/DupeFrag(10519): TestFragment(1080196160).onStart() *** Device rotated (1) *** 05-22 17:39:17.779: VERBOSE/DupeFrag(10519): TestActivity(1080185976).onStop() 05-22 17:39:17.779: VERBOSE/DupeFrag(10519): TestFragment(1080196160).onStop() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestActivity(1080209384).onStart() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080211584).onStart() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080223880).onStart() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080211584).onStop() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080223880).onStop() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080211584).onStart() 05-22 17:39:17.799: VERBOSE/DupeFrag(10519): TestFragment(1080223880).onStart() *** Device rotated (2) *** 05-22 17:39:19.500: VERBOSE/DupeFrag(10519): TestActivity(1080209384).onStop() 05-22 17:39:19.500: VERBOSE/DupeFrag(10519): TestFragment(1080211584).onStop() 05-22 17:39:19.500: VERBOSE/DupeFrag(10519): TestFragment(1080223880).onStop() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestActivity(1080235792).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238000).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238336).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080252384).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238000).onStop() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238336).onStop() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080252384).onStop() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238000).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080238336).onStart() 05-22 17:39:19.520: VERBOSE/DupeFrag(10519): TestFragment(1080252384).onStart() -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Fragments duplicated on config change
As is typical, noticed the r2 release of the compatibility library right after I posted this! That has fixed the duplication issue, however I'm still wondering why each fragment instance inflated from setContentView gets calls to onStart(), onStop(), then onStart() again? Shouldn't there be only a single call to onStart()? -dave On May 22, 5:43 pm, Dave Johnston john...@gmail.com wrote: I'm encountering a peculiar issue with the user of FragmentActivity.

Attempting to call setArguments() after setContentView() results in java.lang.IllegalStateException: Fragment already active. Is it simply preferable to instantiate and add Fragments via code, rather than use fragment inflation from an XML layout? -dave -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Using setArguments() after inflation
Cheers Mark and Dianne. Sounds like setArguments is analogous to XML attributes, whereas I had been using them similarly to Intent data, which now seems so very wrong... -dave On Apr 27, 2:56 pm, Dianne Hackborn hack...@android.com wrote: You use arguments when you are creating it in code, and XML attributes when you are creating from XML. If you want to modify the fragment state after it is made... well just add methods to your fragment to set the state. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] DialogFragment vs showDialog()
Honeycomb introduced the DialogFragment class for producing dialogs. Pre-Honeycomb, applications were encouraged to use managed dialogs handled by their owning Activity via showDialog, dismissDialog etc. Looking forward, should DialogFragments be preferred over Activity managed dialogs, or should they simply be treated as an alternative? -dave -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] getting gps status events

Therefore listening for the status updates without location notifications makes sense only for some kind of a background service when you want to save location whenever somebody else gets it.

[android-developers] Using v4 Fragments with v11 ActionBar tabs
I'm having trouble implementing ActionBar tabs whilst also using backward-compatible Fragments (with the compatibility package). The main issue being that ActionBar.TabListener expects android.app.Fragment, and my Fragment classes inherit from android.support.v4.app.Fragment. Therefore I can't use my Fragments with the ActionBar on 3.0-and-later devices. Anyone have any ideas how I can solve or work around this?

[android-developers] Need help with tabbed layout
I'm new to Android development so please bear with me. I have created
an app in WebOS and I'm keen to try and re-create for the Android
platform. I have tried to follow the tutorial for creating a tabbed
view and to some extent I have succeeded. However, the problem that I
am having is that when I switch from tab to tab any text or graphics
is overwritting the tab elements and not displaying below the tabs
themselves. I'm sure I've done something stupid that is easy to fix.
Here are the files that I have. I have my main class which extends
TabActivity. The code is as follows:
*package com.dtwconsulting.golfcaddie;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.widget.TabHost;
public class GolfCaddie extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(*
*savedInstanceState);
setContentView(R.layout.**splashmain);
* *Resources res = getResources(); // Resource object to get
Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
* *// Create an Intent to launch an Activity for the tab (to be
reused)
intent = new Intent().setClass(this, MainActivity.class);
* *// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec(main).**setIndicator(Main,
res.getDrawable(R.drawable.ic_**tab_main))
.setContent(intent);
tabHost.addTab(spec);
* *// Do the same for the other tabs
intent = new Intent().setClass(this, PlayersActivity.class);
spec = tabHost.newTabSpec(players).**setIndicator(Players,
res.getDrawable(R.drawable.ic_**tab_players))
.setContent(intent);
tabHost.addTab(spec);
* *intent = new Intent().setClass(this, CoursesActivity.class);
spec = tabHost.newTabSpec(courses).**setIndicator(Courses,
res.getDrawable(R.drawable.ic_**tab_courses))
.setContent(intent);
tabHost.addTab(spec);
* *tabHost.setCurrentTab(0);
* *}
* *public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_**menu, menu);
return true;
}
}*
My R.layout.splashmain XML code is as follows:
*?xml version=1.0 encoding=utf-8?
TabHost xmlns:android=http://schemas.android.com/apk/res/android;
android:id=@android:id/**tabhost
android:layout_width=fill_**parent
android:layout_height=fill_**parent
TabWidget android:id=@android:id/tabs
android:layout_width=fill_**parent
android:layout_height=fill_**parent /
FrameLayout android:id=@android:id/**tabcontent
android:layout_width=fill_**parent
android:layout_height=fill_**parent
android:padding=5dp /
/TabHost*
In addition to the above I have a class file for each tab and a layout
file for each tab too. To give an example of the main class and XML
layout file:
*package com.dtwconsulting.golfcaddie;
import android.app.Activity;* *
import android.os.Bundle;
public class MainActivity extends Activity {* *
public void onCreate(Bundle savedInstanceState) {
super.onCreate(**savedInstanceState);
* *setContentView(R.layout.main);
}
}
?xml version=1.0 encoding=utf-8?* *
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:layout_width=wrap_**content
android:layout_height=fill_**parent
android:fitsSystemWindows=**true
android:background=@drawable/**golfcaddie
/LinearLayout
*
So, when this main tab is displayed the background image
(golfcaddie.png) completely displays on the entire screen over the top
of the tabs. I've tried playing around with things but all to no
avail. I either get the background overlaying the tabs, or I get
nothing at all. I suspect that I am just not grasping these layouts
and how they interact.
Any help/direction on this would be much appreciated, and perhaps I am
not even doing this the best way. I ended up Googling about doing a
tabbed view and was lead a little away from the Google docs.

use it. I've searched the web and posted to StackOverflow to try and
figure this out...no luck so far. Any pointers would be greatly

[android-developers] Question of using ksoap for android to call webservices
I am trying to develop an android application using our webservice. Here is the code: private String SOAP_ACTION= http://.../TestFunction;; private String METHOD_NAME = TestFunction; private String NAMESPACE = http://.../;; private String URL = http://.../webservice.php;; SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.setOutputSoapObject(request); HttpTransport androidHttpTransport = new HttpTransport(URL); androidHttpTransport.call(SOAP_ACTION, envelope); The testfunction is a function without any parameters or return values. It is tested correctly using other applications. As long as calling to the last line of code, the emulator exited. I tried Eclipse, Ksoap2 in both Windows and Ubuntu. Can anyone help? Many thanks! Some small questions: 1) do i need to use php?wsdl in URL? 2) do i need to use explict IP address in URL? 3) should I use androidhttptransport? Is it in the ksoap for android? i downloaded but the JAR generates a compile error. 4) Is there any specific requirement for the webservices? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: guitar tuner
Yes, I realize there is an one on the market. In fact, I have that currently installed. But that's not my intention. My main objective is to understand the FFT and frequency analysis so that I can write something else. the guitar tuner is just a simple first step in my understanding. Bret, thanks for the advise.

[android-developers] How AJAX requests work on Android 2.0/2.1 vs. Android 2.2
I'm testing out a web page on the Android 2.0 and 2.2 emulators, and some of the jQuery.ajax() requests that the app makes have slightly different behaviors regarding HTTP Authentication Headers. The server I'm making requests to requires basic authentication, and the ajax requests in 2.2 send the proper auth header. In 2.0, I am debugging with Fiddler, and it seems that the requests do not include the auth header, and the server rejects the request with a 401.2 error. I don't think it matters, but the server is running IIS 7. One interesting thing I noticed while debugging the web requests is that Android 2.2 makes two requests for each resource, whether or not it's an XHR. One does not contain the Auth header, and the second one does. In 2.0, it seems to make 2 requests for everything but XHR's: Here is the 2.2 header for the first XHR: GET http://192.168.1.111/sonar/mobileweb/sonar/views/week/init.ejs HTTP/1.1 Host: 192.168.1.111 Accept-Encoding: gzip Referer: http://192.168.1.111/sonar/mobileweb/sonar/sonar.html Accept-Language: en-US User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/ FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/ 533.1 Accept: text/plain, */* X-Requested-With: XMLHttpRequest Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7 The 2.2 header for the second XHR: GET http://192.168.1.111/sonar/mobileweb/sonar/views/week/init.ejs HTTP/1.1 Host: 192.168.1.111 Accept-Encoding: gzip Referer: http://192.168.1.111/sonar/mobileweb/sonar/sonar.html Accept-Language: en-US User-Agent: Mozilla/5.0 (Linux; U; Android 2.2; en-us; sdk Build/ FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/ 533.1 Authorization: Basic cGFyaXZlZGFcZGF2aWQubW9ycmlzOjIzbkx2ZWxsbGw= Accept: text/plain, */* X-Requested-With: XMLHttpRequest Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7 And the 2.0 header: GET http://192.168.1.111/app/views/week/init.ejs HTTP/1.1 Host: 192.168.1.111 Accept-Encoding: gzip Referer: http://192.168.1.111/app/app.html Accept-Language: en-US User-Agent: Mozilla/5.0 (Linux; U; Android 2.0; en-us; sdk Build/ ECLAIR) AppleWebKit/530.17 (KHTML, like Gecko) Version/4.0 Mobile Safari/530.17 Accept: text/plain, */* X-Requested-With: XMLHttpRequest Accept-Charset: utf-8, iso-8859-1, utf-16, *;q=0.7 Notice that 2.0 (and 2.1) only makes the first request, recieves the 401 challenge, and then does not make the second request with the proper auth header.
