Re: [android-developers] Using ACTION_OPEN_DOCUMENT for editing files
Yep, you're right that checking FLAG_SUPPORTS_WRITE is the best way to check if a write is allowed. If you're really looking to focus on writing data, then ACTION_CREATE_DOCUMENT might be a better fit, since it also lets the user select an existing file, and it filters to only allow selection of documents that have FLAG_SUPPORTS_WRITE set. I'm thinking that allowing an app to request filtering of read-only documents during a OPEN_DOCUMENT request would lead to user confusion because of the inconsistency between apps. (For example, a user would still expect to open a read-only document for viewing purposes.) If a user then tried saving changes to a read-only document, it makes sense for the app to use CREATE_DOCUMENT to ask them to save the modifications somewhere else. Hope this helps. :) j On Wed, Jan 1, 2014 at 9:05 PM, Dave Smith dasmith1...@gmail.com wrote: 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.

Re: [android-developers] Re: MediaPlayer suddenly stopped working in Android 4.2
Starting in Android 4.2, processes may have different views of the
filesystem depending on which user they're running as. For example,
/sdcard/foo.mp3 could refer to different files for different users.
To correctly disambiguate filesystem paths, you'll need to open the
file in your app process and pass the FileDescriptor to the
mediaserver (which is shared between all users on a device).
Something like this should work:
MediaPlayer player;
FileInputStream fis = new FileInputStream(myFile);
try {
player.setDataSource(fis.getFD());
} finally {
fis.close();
}
It sounds like the setDataSource(String path) method needs to be
fixed; tracking in 7962739.

Re: [android-developers] Re: appwidget Image on Orientation Change Issue
Remember that widget RemoteViews updates are applied over a potentially-cached layout. You should always set all values on each update you send. For example, if the last update you passed only updated a TextView, that single update could potentially be applied over the top of a brand new layout (such as after an orientation change). j On Sun, Nov 29, 2009 at 3:20 AM, Ryan rgra...@gmail.com wrote: Ok I think I figured it out. In certain cases when the widget is clicked i updated the RemoteViews to hide some on screen controls/ views using setViewVisibility on the remoteview, however I did not re- set the setImageURI. When the screen rotated the Image dissappeared. However this is odd because I would expect the image to dissappear on updating the RemoteView without the ImageURI even without rotating the screen. But it would only dissappear after rotating. When I did not go through the routine that hid the controls/ did not set the setViewVisibility, the image did not dissappear on rotation. I am curious as to what happens to the RemoteView on orientation change and why sometimes it seems to retain the ImageURI and others it loses it.

Re: [android-developers] Re: [Android 2.0] Contacts FAQ?
4) What sort of identifier should I represent a contact with in my local data, so I can later get their most-current data? Use lookup-style Uris, as they are designed to help with fuzzy resolution when the contact changes, or is split/joined by the user. Contacts.getLookupUri() and Data.getContactLookupUri() can help you build these lookup Uris from columns when you already know them, or from normal ContentUris.withAppendedId()-style Uris. 6) How do I add a contact to the address book from within an app? One of the easiest ways is to use Intents.Insert, since it doesn't require adding the WRITE_CONTACTS permission to your app: http://d.android.com/reference/android/provider/ContactsContract.Intents.Insert.html 7) How do I add custom data to a contact? Pick a well-scoped MIME-type and just start using it as Data.MIMETYPE when inserting custom Data rows. For example, a row describing a VoIP profile might use something like vnd.android.cursor.item/vnd.com.example.voip.profile. 9) How do I /get/ the nifty status messages and the source for them (a'la 'Away for lunch' on 'Google Talk,' or 'eating a pie!' on 'Facebook'), so I can display them alongside a contact in my own app? (Alternatively, some ask how they can set the nifty status messages and have them appear in the QuickContact bar or in other apps.) Status messages like that can be read through StatusUpdates, and each row is strongly tied to a Data row. When status information is displayed across the system, there is logic that picks the best update based on timestamp. http://d.android.com/reference/android/provider/ContactsContract.StatusUpdates.html To add StatusUpdates you should attach them to a specific RawContact owned by your application. (This allows users to split and join the RawContact from your service to the correct person in their address book.) 10) How do I add an action to the QuickContact bar for a contact? This is partially covered in this thread: http://groups.google.com/group/android-developers/browse_thread/thread/fe814aa9149da1f0/ When Quick Contact encounters a custom Data row, it follows that row back to the owning sync adapter (through ACCOUNT_NAME and _TYPE) to look for XML metadata that describes how to render the row, both as a list item when viewing the contact, and as a Quick Contact icon. The Quick Contact case also performs PackageManager queries to find apps that support ACTION_VIEW on the custom MIME-type defined for that row, which means you'll need to add an intent-filter. 13) How do I add a contact to a group? 14) How do I remove a contact from a group?

So it seems we have an inconsistency in the way the class loader works
for the same apk.
WORKS - Launch the application by itself, without invoking the Widget.
DOES NOT WORK - Create a Widget on the Home screen and then launch the
application from the launcher.
The source code for this application (http://www.yousendit.com/
download/TzY3ZGVhZy96NE4zZUE9PQ) has been attached. Hope someone from
the Android team can shed light on this behavior.
BTW, this error is seen on the 1.5r3 SDK. Not sure if this has been
addressed in 1.6 and 2.0 SDKs..
Thanks,
Himanshu.

Re: [android-developers] Trap in TabHost when AsyncTask delays setContentView at activity startup

[android-developers] Re: Quick Contacts popup
The easiest way is using the new QuickContactBadge widget. You can add it to your layout, and there are helper methods to bind it using phone, email, or a normal Uri. http://d.android.com/reference/android/widget/QuickContactBadge.html This control will automatically give you the frame around the photo, and launch the track when clicked. If you're looking to launch the Quick Contacts popup manually yourself, you can use the API directly: http://d.android.com/reference/android/provider/ContactsContract.QuickContact.html Just call QuickContact.showQuickContact() and pass in a target Rect area in screen coordinates. The Quick Contact window adjusts and points towards that target area. j On Thu, Oct 29, 2009 at 5:13 AM, Fedor Vlasov the...@gmail.com wrote: I can see a new Quick Contacts popup in Android 2.0.

[android-developers] Re: setResult() for AppWidget
It sounds like the ACTION_VIEW might be launched as startActivity()
instead of startActivityForResult(), which means the result is being
dropped on the path back to Launcher.
The forecast widget example interacts with the system search dialog,
and uses singleTop and onNewIntent() to catch searches and still
return correctly:

Now I'm trying to do the same for Phones.CONTENT_URI (Android = 1.6) and ContactsContract.PhoneLookup.CONTENT_FILTER_URI (Android = 2.0) which is needed by step 2) mentioned above. But as soon as I try to get a contentResolver by using ContactsContract.PhoneLookup.CONTENT_FILTER_URI I get the following exception: java.lang.IllegalArgumentException: Unknown URL content://com.android.contacts/phone_lookup This looks really strange to me, since it should be correct (it is part of the official API)! Moreover, I tried to look at the API Demos project, in particular to the classes: com.example.android.apis.view.List2 com.example.android.apis.view.List3 which are still using the deprecated People.CONTENT_URI and Phones.CONTENT_URI and thus no data (i.e. contacts) is loaded (of course I have sample contacts in the emulator). - Do you have any suggestion to solve this problem? - Or is there another approach I can use to get the name of a contact based on one of his/her numbers? (This must work on all versions of Android) Thank you ;-) Andrea -- Jeff Sharkey jshar...@android.com -- Jeff Sharkey jshar...@android.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Contacts extension - Further developments ?
Earlier today we released the Android 2.0 SDK, which has a much-improved contacts API: http://d.android.com/reference/android/provider/ContactsContract.html Each Data row has 15 fields that can be used to store generic data, and the Data.MIMETYPE column can be used to identify the contents of a given row. If you're storing contact data, you should definitely try to leverage the existing CommonDataKinds, since most UI will understand how to render them. If you need to store custom data, just allocate a unique MIME-type. For example, something like vnd.edu.example.cursor.item/contact_class would work. j On Fri, Oct 9, 2009 at 10:09 AM, Sarab sarab.n...@gmail.com wrote: Dear Fellow Developers, I would like to request your comments on : How to add new field(s) in to android's contacts.db database ?

[android-developers] Re: Extending contacts
If the VoIP app can complete calls to any normal phone number, it should have an intent-filter for normal tel: style Intents, which allows you to leverage any phone numbers already entered by the user. If the VoIP contact method is instead something like a username, you can insert a custom Data row under a RawContact. http://d.android.com/reference/android/provider/ContactsContract.html For that custom Data row to appear in the Contacts app, you'll need to associate your custom MIME-type with XML that describes how to render the UI. The only current way of doing this is to define a sync adapter service and add meta-data definition inside, something like this: meta-data android:name=android.provider.CONTACTS_STRUCTURE android:resource=@xml/contacts / Then define the XML inside your app: --snip-- ContactsSource xmlns:android=http://schemas.android.com/apk/res/android; ContactsDataKind android:mimeType=vnd.com.example.voip.cursor.item/voip_profile android:icon=@drawable/icon android:summaryColumn=data2 android:detailColumn=data3 / /ContactsSource --snip-- j On Wed, Oct 14, 2009 at 2:01 PM, dreamerns dreame...@gmail.com wrote: I know this question was asked couple of times in this list, but I haven't found any answer in archives, and last time this subject was debated almost a year ago.

One way of doing this would be to convertView.setTag() to a well-known value when binding each child item.

Each time a view is recycled, your bind step above would be updating the tag to match the content. j On Wed, Aug 12, 2009 at 2:34 AM, Neilneil.wilkin...@gmx.com wrote: Hi, I've recently got into Android development and am writing a basic podcast app as a learning exercise.

Rather than post code (it's getting big!), I'll try and summarise: I have an ExpandableListView showing podcasts and each podcast's episodes in a simple two-level tree. The podcasts are downloaded in a Service, and this Service 'sends' messages by using an interface registered by the main Activity. This interface then uses a handler to update the UI. The child views in the ExpandableListView are LinearLayouts with one TextView and two ViewStubs, one for showing an image and one for showing a horizontal ProgressBar.

[android-developers] Re: ambiguous column name: _id when querying the contacts list
Ouch, there isn't a good solution in the current SDK. In Eclair we're
restructuring this code, which would break the people._id solution
you mentioned. :( And you're right, there otherwise isn't a good way
of selecting multiple _ids.
Ironically, the same change that breaks the people._id approach also
fixes the _id ambiguity problem, lol.
I'm afraid the answer is to use people._id for now, and update it
when the Eclair SDK is released.

[android-developers] Re: ambiguous column name: _id when querying the contacts list
Using the SDK version to handle the logic sounds like a good solution.
You should use Build.VERSION.SDK (instead of RELEASE), since its
values are much more predictable. (The SDK always increments by 1
for each platform release; Cupcake was 3, Donut will be 4, Eclair will
be 5.)
Also, a side note, you should look at using StringBuilder to make your
loop more efficient. The code you pasted is allocating two new String
objects for each pass through the loop, which are then immediately
marked as garbage. Here's a slightly more efficient way of doing the
same loop:
StringBuilder recycle = new StringBuilder(();
for (Integer friend : friends) {
recycle.append(friend);
recycle.append(,);
}
// Replace last comma with clause termination
recycle.setCharAt(recycle.length() - 1, ')');
final String where = recycle.toString();
For clarity purposes that code uses an iterator, but it's slightly
faster to use direct indexing like you originally had:

Ouch... I met the same problem. So is it possible to maintain a version

I assume that checking the version number and using the cludgy way if

float version = Float.parseFloat((new Build.VERSION
()).RELEASE);
if(version 2.0f)
{
WHERE += people._id;
}
else

[android-developers] Re: default measuring units px or dp
You're right, setting dimensions through code only takes raw pixel values. You have to multiply the display density; something like this should work: final float density = getResources().getDisplayMetrics().density; int pxSize = (int)((float)dipSize * density); Or if you're writing your own views, you can use TypedArray.getDimensionPixelSize() to read values as raw pixels. j On Thu, Aug 13, 2009 at 2:29 AM, Atif Gulzaratif.gul...@gmail.com wrote: in xml file we can define measuring units along with the values.

[android-developers] Re: How can I update values in contacts.db in a transaction.
The current (1.5_r3) ContentResolver API doesn't offer bulk updates,
or a method of wrapping multiple operations into a transaction. One
way to optimize your code is to allocate a single ContentValues object
outside of the loop, and recycle it during each pass by calling
clear(). (Currently you're allocating a new object for every update,
which can get expensive.)

After you allocate the appWidgetId, you need to launch the android.appwidget.action.APPWIDGET_PICK intent, which will show a dialog that lets the user pick which widget to bind.

In fact, only the platform can bind them, since binding is the primary security mechanism for widgets. If apps could bind widgets programmatically, one could imagine a bad app that would bind to your Calendar widget without your knowledge and slowly scrape updates about your personal events over time, etc. Once the user has successfully finished the binding process, your onActivityResult() is called, and shortly thereafter you should start receiving RemoteViews updates from that widget the callbacks you registered through AppWidgetHost.startListening(). j On Thu, Aug 6, 2009 at 4:45 AM, karansmwankh...@gmail.com wrote: hi, You need to bind your widgets id first, and for doing that you need to do two things 1) you will need a permission for binding 2) you will need to share your process id.

DTMF is sent flicking up the 'dialpad', and speaker (and other options) is found in the 'menu'. I think that this is confusing. All should be put in the menu or dialpad, but not both, or maybe put a frequent option SPEAKER on the dialpad. I often dial, then press MENU to select speaker, then have to flick DIALPAD to type in DTMF digits, then when the call is established, press MENU again and deselect speaker. This is too much!!

[android-developers] Re: ProgressBar doesn't allow control of visibility in AppWidgetProvider App Widget?
Doh, good catch. The View.setVisibility() method is marked with the
@android.view.RemotableViewMethod annotation, which is what allows it
to be called through RemoteViews. In this case, ProgressBar actually
overrides the default View implementation, but without adding that
annotation. (This is why it throws the exception.)
One quick workaround is to wrap the ProgressBar into a simple view
like FrameLayout, and then setVisibility() on that wrapper.

It's actually really easy, and you don't need to use animations. I

private Matrix mForward = new Matrix();
private Matrix mReverse = new Matrix();
private float[] mTemp = new float[2];
public FlipLayout(Context context) {
super(context);
mForward.postRotate(180);

something akin to a transformation, except to be used on a TextView or

I have considering overriding methods to accomplish this task by
slightly modifying the animation code, but I'm not sure how extensive
the work for this would be. Additionally, I'm not sure where to find
the source for those methods.
If anyone could recommend a means of accomplishing this task, whether
it be by an override or perhaps something simple that I am missing, I
would appreciate it very much. Thanks!

flipped upside-down and stays that way. I found the Rotation Animation
method, but I have been unable to find a means of keeping the view
rotated. Repeating the animation doesn't suit my purposes, and in fact
I don't want an animation at all if possible. What I would like is
something akin to a transformation, except to be used on a TextView or
a LinearLayout.
I have considering overriding methods to accomplish this task by
slightly modifying the animation code, but I'm not sure how extensive
the work for this would be. Additionally, I'm not sure where to find
the source for those methods.
If anyone could recommend a means of accomplishing this task, whether
it be by an override or perhaps something simple that I am missing, I
would appreciate it very much. Thanks!

Does this imply that EVERY RemoteViews update that I apply to my widget should be capable of COMPLETELY initializing the correct current state of every component on the widget? Yes, that's correct. This is because you can't infer anything about the current remote state. That remote state might have some actions pre-applied from a previous RemoteViews object, or it might be applied over a newly-inflated layout, for example if Launcher was forced out of memory.

Is it possible to disable a button on a Cupcake desktop widget? Not directly, but you could send a widget update that swaps out the drawable used and clears the PendingIntent. Or, keep two buttons in your layout, and visible/gone them as needed. The current Google Search widget disables the search button until a user enters text, then the button is disabled. Is this only allowed for special widgets, or is there an approach available to third- party widgets? The Google Search bar on the desktop looks and feels like a widget, but it isn't a real widget. It lives directly in the Launcher app, which is how it does things like auto completion.

In particular, mEditMode is what enables the reorder mode: http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/TrackBrowserActivity.java;hb=cupcake Hope this helps. j On Mon, Jun 15, 2009 at 3:10 PM, Walterwhri...@gmail.com wrote: Has anyone been able to create a sortable ListView (one where you can drag items around to change their order)? -- Jeff Sharkey jshar...@android.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: BroadcastReceiver not able to receive events
You need to resolve the Java variable names to their actual String
constants when inserting into XML. For example, the below Java
variable resolves to the actual string
android.intent.action.MEDIA_MOUNTED which is what you would use in
the intent-filter.

[android-developers] Re: Changing the application icon at runtime?
Actually, it totally can take focus. :) The forecast widget I wrote can be selected and clicked using the trackball: http://code.google.com/p/android-sky/source/browse/trunk/Sky/res/layout/widget_med.xml You may need to use tricks like android:duplicateParentState to correctly show drawable states in children views. j On Thu, Jun 11, 2009 at 4:24 AM, Tom Gibaram...@tomgibara.com wrote: I just want to add that one thing about this: a widget can't take focus or otherwise be operated via the trackball, that might prove an irritation for some users. Tom. 2009/6/11 Jeff Sharkey jshar...@android.com Changing icons dynamically still isn't possible. However, you can now write an AppWidget the size and shape of an icon that dynamically changes. j On Wed, Jun 10, 2009 at 12:24 AM, toff...@gmail.comtoff...@gmail.com wrote: Hi, I'm also trying to find out if this is possible to do.

[android-developers] Re: Hide application in Home dinamically
You can try PackageManager#setComponentEnabledSetting(), though I have not tried this personally. Yep this should work perfectly. In fact, it's how the Email app hides/shows itself in Share lists across the system dynamically, based on if you have an account setup. -- Jeff Sharkey jshar...@android.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.
