from:"Mark Wyszomierski"

Hi,

Is there a way to leave a version of an app on the marketplace (which
is 1.5 compatible) and then put up a new version which is 1.6 and
above compatible? The idea being that any 1.5 users going to
marketplace can only download the 1.5 version, everyone else sees the
1.6+ version?

I'm running into frequent view inflation issues on 1.5, it's like
trying to develop for ie6. I have a version of the app which works
great on 1.6+, limps along on 1.5. I'd like to just cut support for
1.5 here, and move on with 1.6+ since I'm spending too much time
trying to make sure the views don't blow up on 1.5. Any way to do
this?

Thanks

Re: [android-developers] Dropping support for 1.5, separate build for those users on marketplace?

Right now, I'll generate two apks:

   Foo.apk
   Foo-1.5-final.apk

They'll both have the same package names. Should I just change the
'versionName' in the manifest:

// Foo.apk
manifest
   android:versionName=Foo /

// Foo-1.5.apk
manifest
   android:versionName=Foo-1.5-final /

then upload Foo.apk as usual (os targets updated of course), and
Foo-1.5-final.apk should be uploaded as a completely separate application to
marketplace, right? Then I basically have to tell 1.5 users that they should
search for Foo-1.5-final if they want to use my app, they won't see Foo.apk
at all.

Is that right?

Thanks

 Set the 1.5 version to max and target SDK = 3 and the 1.6+ version to
 maxSDK = 8 (or whatever) and target to whatever you prefer, then update to
 Market. It should automatically filter your apps based on the platform the
 user is running, so only 1.5 users will see the 1.5 version and everyone
 else will see the 1.6 version.

 Market won't let you upload two different apps with the same package
name.

Ah ok that's what I was thinking. Ok thanks for all the info,

Mark

 Wouldn't for me, anyway.

 I have a separate cupcake build, but the package name has 'cupcake'
 appended.

 I set:

 Cupcake: minsdk 3, maxsdk 3
 Other: minsdk 4

[android-developers] Re: Setting layout attributes based on android OS version?

Using a relative layout did help in this case - after some more
testing, I found that TextView is still causing problems when
maxLines=1 / singleLine=true. Taking the same relative layout, I can
toggle those on and off, and cause a stackoverflowexception when
they're on. This is only on 1.5, later os versions work great.

Is there a way to specify a 1.5 layout folder though, similar to the
drawable resources, or landscape folders? Something like:

   /layout
  mylayout.xml

  /layout-v3
  mylayout.xml

if running on 1.5, then the second layout would be used, if not, then
the layout in the general /layout folder would be used?:

Thanks

 A bit of additional information found through more testing - if I
 restrict each of the textviews to be at most one line with the
 following:

  android:maxLines=1
  android:singleLine=true

 then it works fine (even with the background drawable set). If I let
 any one of the text views go more than one line in height, the
 exception will be thrown. It is thrown as soon as I start scrolling
 (for example, even if I scroll very slowly, by one pixel). My list
 adapter isn't getting called to fetch another view as all are on
 screen at this point, it looks like some drawing state which happens
 when the list is being animated maybe? I'm not sure what other
 combinations I can try here in attributes on the text views, I was
 hoping that setting:

  android:ellipsize=none
  android:singleLine=false

 would get around whatever state it being hit, but no luck,

[android-developers] Re: Activity onResumed not getting called

2010-09-23 Thread Mark Wyszomierski

Yeah I think by default if the app is not resumed for some period of
time, android will restart the app instead of resuming it:

http://developer.android.com/guide/topics/manifest/activity-element.html

look at:  android:alwaysRetainTaskState

 therefore loosing the previous state, it behaves as that screen is the

 Has anyone seen a similar issue. Does someone know if this is a normal

[android-developers] ListView elements with background drawable go transparent on menu display?

2010-09-23 Thread Mark Wyszomierski

Hi,

I have a ListView, my rows each have a background drawable set. One
strange quirk is that if I have a row selected (it is orange now),
then hit the context menu, the orange focus color is lost, the row
background is made transparent. When I dismiss the context menu,
orange focus is returned to that element. This is what my setup looks
like:

   ListView
  LinearLayout
android:background=@drawable/some_simple_png /
   /ListView

The above is not really defined like that in the xml layout file, it's
just an example. I'm not sure if there is a fix for this.

Thanks

[android-developers] When to add child views to a compound control?

2010-09-20 Thread Mark Wyszomierski

Hi,

I'm trying to make a compound control which looks like the following:

  LinearLayout
ImageView /
ImageView /
...
  /LinearLayout

I want to fill a horizontal linear layout with as many image views as
possible - but only a single row of them. I'm not sure where to add
the image views to the layout at runtime, I am getting inconsistent
results, for example:

  class Foo extends LinearLayout {
  void onLayout(boolean changed, int l, int t, int r, int b) {
  super.onLayout(changed, l, r, t, b);
  addAsManyImageViewsAsCanFit(r-l);
  }

  void addAsManyImageViewsAsCanFit(int width) {
  while (we can fit more) {
  ImageView iv = new ImageView(getContext());
  iv.setLayoutParams(...);
  addView(iv);
  }
  }
  }

I'm sure image views are getting added as child views, but they don't
always take up space in the layout somehow (I'm giving them a fixed
width and height for now). Where should I be adding the image views to
the layout? onLayout? onSizeChanged? After adding each one, do I need
to call requestLayout() or some other method on the parent?

Thanks

Re: [android-developers] Same color specified in xml file and png appear differently?

I'm not quite sure what's going on - if I specify the color in my layout xml
like so with alpha = FF:

   #ffebebeb

then at least in the layout editor it now matches the color of my png
(created in photoshop, with the same #ebebeb specification). When I run the

Re: [android-developers] Same color specified in xml file and png appear differently?

Yeah I guess that's why I'm confused, the alpha of my png is 100%. So when I
set the background color in the xml file to explicitly have alpha = ff, then
the layout editor shows the two colors matching. It's just that when I run
the app, the emulator (and n1 at least) show the background color (not the
png) as the different grey, same as when I was previously *not* setting the
alpha = ff. To sum it up:

   before:
  background=#ebebeb
  drawable in photoshop (100% alpha, ebebeb)
  layout editor and emulator show background as a purplish-grey.

   now
  background=#ffebebeb
  drawable (unchanged from before)
  layout editor shows background now matching my drawable,
  but at runtime it looks like the purplish grey from before.

I'm not modifying the color at runtime (which could explain the difference),
I'll make a separate test app to try and demo it,

Thanks

 Well, you are halfway there.

 For starters, you need the alpha value of your background color to be
 the same as the alpha value of your PNG file. You know what the alpha
 value of your background color is, because you are setting it. Now,
 you need to determine the alpha value that Photoshop used with your
 PNG file.

 Also, if you choose a non-opaque (i.e., less than FF) alpha, things
 get more complicated, as you have to take into account the stuff the
 alpha channel is blending from behind the respective widgets.

[android-developers] StateListDrawable and activity-menu-shown state?

Hi,

I have a linear layout that is focusable, I'd like it to use the same
background drawable as found in listview items:

StateListDrawable sld =
(StateListDrawable)context.getResources().getDrawable(
android.R.drawable.list_selector_background);
linearLayout..setBackgroundDrawable(sld);
linearLayout.setFocusable(true);

The default state of this selector is to be transparent, but I want a
specific background drawable used in an unselected state. It would be
ideal if we could just override this one state, and leave everything
else the same:

sld.addState(new int[] { -android.R.attr.state_window_focused },
context.getResources().getDrawable(R.drawable.my_background));

That seems to work - but if I display a menu in the parent activity,
the background reverts to transparent again. When the menu is hidden,
the background comes back to the drawable I had used for the override.
I'm not sure what states I could override to fix the menu-display-
state-issue - but I'm not sure if this is even a proper use of
StateListDrawables. I could just make my own sld to mimic what the one
bundled with android does, but if I make its highlight state orange
for example, it'll look strange on some devices that have changed the
focus color to green for example with listviews (droid eris for
example). It'd be great to keep everything consistent.

Below is the xml def for android.R.drawable.list_selector_background.
If anyone knows what states to change for the menu display, that'd be
great.

Thanks




   selector xmlns:android=http://schemas.android.com/apk/res/
android

   item android:state_window_focused=false
   android:drawable=@color/transparent /

   !-- Even though these two point to the same resource, have two
states so the drawable will invalidate itself when coming out of
pressed state. --

[android-developers] Exposing data to third-party apps in a synchronous call?

2010-09-17 Thread Mark Wyszomierski

Hi,

I've got an application, and I'd like to publish a way for third-party
services to get data from it. Ideally I could expose this  through
intents, as in the following pseudocode:

   // third party apps
   class ThirdPartyService extends Service {
   @Override
   public void onCreate() {
   Intent i = new Intent(this, com.me.test.MyAppIntent);
   Intent result = startActivity(i);
   }
}

// part of my app
class MyAppIntent extends Activity {
   @Override
   public void onCreate() {
   Intent i = new Intent();
   i.putExtra(result, hi there);
   setResult(i);
   finish();
   }
}

The above won't work of course - I have some work done on this, just
wondering if anyone has any recommendations or best practices?

Thanks

[android-developers] Re: Exposing data to third-party apps in a synchronous call?

2010-09-17 Thread Mark Wyszomierski

Yeah exactly, I was wondering if I was missing a way to pass data
synchronously using intents, similar in a sense to the way activities
can do it with startActivityForResult(). I haven't looked at the aidl
remote service stuff in about a year, and forgot whether that lets the
processes communicate synchronously, but it seems like a good deal
more code to add to support it. There is also the content provider as
you mentioned, I'm not sure if that allows synchronous access.

I implemented a simple asynchronous scheme for now as follows:

  class ThirdPartyService extends Service {
  void doWork() {
  Intent intent = new Intent();
  intent.setClassName(myapp, myapp.MyService);
  intent.putExtra(callbackpackage, thirdpartyapp);
  intent.putExtra(callbackclassname, ThirdPartyReceiver);
  startService(intent);
  }
  }

  class ThirdPartyReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
  .. do something with the data sent back from my app ..
  }
  }

  class MyService extends IntentService {
  @Override
  public void onHandleIntent(Intent intent) {
  Intent i = new Intent();
  i.setClassName(
  intent.getStringExtra(callbackpackage),
  intent.getStringExtra(callbackclassname));
  i.putExtra(somedata, hi there);
  sendBroadcast(i);
  }
  }

So the third party sends an intent which gets picked up by MyService.
They supply their package and classname as extras in the intent. After
my service is done working, I can broadcast a result intent back to
them (I could send it via startActivity() too). They have to mark
their receiver as exported=true. Then they can do whatever they want
with the data in the intent. It works, but it's not as convenient (for
the third party) as exposing some asynchronous call mechanism. Then
they will get the data in the calling context.

I'll check out the content provider and the aidl interfaces to see if
those would be more convenient,

Thanks

   Mark,

 Your subject says synchronous - afaik, only content providers are
 synchronous. Service startup / binding is asynchronous, binder requires
 a service (although I could be wrong on this one), and so is
 asynchronous as well. Intents are of course asynchronous too.

 A content provider doesn't have to be backed by SQL, or to really
 implement data storage - you could pass various commands encoded in the
 URI, returning results in your own Cursor implementation.

 If you are keen on using intents, though - your code is pretty close,
 but you need to use startActivityForResult rather than startActivity, so
 that you can retrieve the result (set with setResult) later. This can't
 be used from a Service, only from an Activity, though.

[android-developers] Get a parcel from intent's extras?

2010-09-16 Thread Mark Wyszomierski

Hi,

I've implemented parcelable on a class of mine per the doc
instructions, works fine:

public class MyParcelable implements Parcelable {
...
public static final Parcelable.CreatorMyParcelable CREATOR
 = new Parcelable.CreatorMyParcelable() {
public MyParcelable createFromParcel(Parcel in) {
   return new MyParcelable(in);
}

...
};
}

I'm interested in the createFromParcel() method. I pass an instance of
MyParcelable to a new activity like this:

Intent intent = new Intent(...);
intent.putExtra(key, myParcelableInstance);
startActivity(intent);

and pick it up from the new activity like this:

MyParcelable mp =
(MyParcelable)getIntent().getExtras().getParcelable(key);

I'd like to make a copy of the MyParcelable instance, like so:

MyParcelable mp2 = new MyParcelable(mp);

but I haven't implemented a copy constructor. However, the
createFromParcel() method which I did implement is almost like a copy
constructor. I'm wondering if I can use it make a copy, but I can't
figure out how to get a Parcel instance from the intent extras:

MyParcelable mp2 =
MyParcelable.CREATOR.createFromParcel(
getIntent().getExtras().getParcelable(key));  // ? just
need a parcel ?

it's not the greatest idea, just wondering if it's possible to avoid
making another method for my class which will almost be identical to
what's already implemented for the Parcelable interface,

Thanks

[android-developers] Re: Any way to animate a 2D Game Smooth without OpenGL ?

I had similar problems trying to get a smooth game loop going, I just
couldn't get rid of gcs happening (I think some were occurring outside
my app too). I think I had removed everything from the draw loop in
frustration except for drawing a rectangle, but would still get the
bumps. That was about 7 months ago, hadn't had a chance to try any
other improvements since then.

[android-developers] Does TabWidget.setDividerDrawable() work?

Hi,

Is TabWidget.setDividerDrawable() functional? I'm trying to use it,
passing it a 1px-wide 9 png stretchable, but no dividers are drawn
between my tabs:

  tabWidget.setDividerDrawable(R.drawable.myDivider);

when used, touches then seem to break, like if I tap the 1st tab, the
3rd then gets selected. If I tap the last tab, I get a force close as
I guess it thinks I'm trying to click a tab index that does not exist,

[android-developers] Setting layout attributes based on android OS version?

Hi,

Is there a way to specify a background in a layout based on OS
version?:

  android:background_1.5=@color/white
  android:background_above_1.5=@drawable/mybackground

I'm running into a problem where using a 9 png drawable for the
background causes a stack overflow exception on a listview item (stack
trace shows its related to a child TextView - drawText()). The layout
is simple:

  LinearLayout
 ImageView /
 TextView /
  /LinearLayout

and the background works fine on 1.6 and above. It's just 1.5 that's
having the issue. If I set the background to be a color, it works
fine.

Thanks

[android-developers] Re: Setting layout attributes based on android OS version?

Yes, I can easily set the background drawable in java code at runtime,
it would just be easier to maintain if I could specify the quirk in
the xml file - just wondering if there's a way to do it, if not, I'll
just modify at runtime,

Thanks

[android-developers] Re: Setting layout attributes based on android OS version?

Cool I'll check out those facilities. Pasting the exact layout below.
I can't nail down exactly what's causing this. The first render of the
listview works ok. The first attempt to scroll generates the exception
(pasted below). I tried using a 9 png drawable direct from the android
project, same behavior. If I just get rid of background drawable
specified in the top-level linear layout, it works fine. The parent
listview has nothing custom in it, just part of a ListActivity:

[android-developers] Re: Setting layout attributes based on android OS version?

A bit of additional information found through more testing - if I
restrict each of the textviews to be at most one line with the
following:

  android:maxLines=1
  android:singleLine=true

then it works fine (even with the background drawable set). If I let
any one of the text views go more than one line in height, the
exception will be thrown. It is thrown as soon as I start scrolling
(for example, even if I scroll very slowly, by one pixel). My list
adapter isn't getting called to fetch another view as all are on
screen at this point, it looks like some drawing state which happens
when the list is being animated maybe? I'm not sure what other
combinations I can try here in attributes on the text views, I was
hoping that setting:

  android:ellipsize=none
  android:singleLine=false

would get around whatever state it being hit, but no luck,

Thanks

[android-developers] Getting TabWidget.setDividerDrawable() to work?

2010-09-13 Thread Mark Wyszomierski

Hi,

I've got a TabHost/TabWidget, I'm supplying custom views for each of
the tabs, works great. I'm not sure if setting the divider drawable
and the left and right strips is working as I'm assuming. Basically I
supply a drawable, and no divider is drawn, nor is the left/right
strips. Are those methods meant to be used for this? When I look at
the tab drawables in the project, it looks like they have the dividers
and strips baked into the tab drawable resources themselves. Does
anyone have this working?:

// The drawable is a dummy png that is 1px wide and 65px tall:
mTabHost.getTabWidget().setDividerDrawable(
R.drawable.mydividerdrawable);

Thanks

[android-developers] TextColor attribute doesn't get applied to Button from a style def?

2010-09-09 Thread Mark Wyszomierski

Hi,

I have a button, and am applying a text style to it:

Button
  android:textAppearance=@style/foo
  /

the color defined in the style doesn't get applied to the button
though:

style name=foo
  item name=android:textSize18dip/item
  item name=android:textColor#F00/item
/style

the other style elements do get applied though (like the textSize). I
can get the text color to change if I explicitly set it on the button:

   Button
  android:textAppearance=@style/foo
  android:textColor=#F00
  /

am I doing something wrong?

Thanks

[android-developers] Pass text style from compound view to child text view?

2010-09-08 Thread Mark Wyszomierski

Hi,

How can we pass through a text style to our own compound control? For
example, I have the following:

com.me.test.MyCompoundView
  android:layout_width=fill_parent
  android:layout_height=wrap_content
  android:textAppearance=@style/TextStyleFoo

public class MyCompoundView extends LinearLayout {
TextView mTextView;

public MyCompoundView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray a = context.obtainStyledAttributes(...);

// How do we pass the text style in the xml def
// to our child textview here?
mTextView.setTypeFace(...?...);
}
}

yeah I'm not sure what the correct way to do it is, thanks for any
pointers,

Mark

nice), write to the prefs, stuff like that.

[android-developers] Where is the View.setStyle() method?

2010-09-03 Thread Mark Wyszomierski

Hi,

Is there a way to set a style for a View at runtime? I've seen this
question a few times on the board here but no answers, so probably
not:

  ImageView
android:id=@+id/blah
style=@style/mystyle
/

  // later...

  ImageView iv = (ImageView)findViewById(...);
  iv.setStyle(R.style.myotherstyle);

is it not possible to do something like this? We have to manually
change everything in code instead?

Thanks

[android-developers] Re: Where is the View.setStyle() method?

2010-09-03 Thread Mark Wyszomierski

Ah well, is there any better and new way of setting pixel sizes at
least for a view? For example, my two styles had different image
widths:

   // style1:
   layout_width=25dip

   // style2:
   layout_width=50dip

Doing something like this:

   myView.setLayoutParams(new LinearLayout.LayoutParams(50, 50));

would not set the sizes in dip, scaled for the current device display
specifics. I could grab the device density and scale myself, but are
there any other better ways of doing this? Like if I could read the
values from my styles in styles.xml and let it rescale for me? I doubt
it, but just wondering if there's some way to utilize the dip system,

Thanks

[android-developers] Sync Adapter and api level 3 4?

2010-07-30 Thread Mark Wyszomierski

Hi,

I'm looking at the sample sync adapter here:

  http://developer.android.com/resources/samples/SampleSyncAdapter/index.html

I'd like to still support sdk level 3 and 4 devices. Will including
the following lines in my app's manifest be problematic?:

  uses-permission
android:name=android.permission.AUTHENTICATE_ACCOUNTS /
  uses-permission
android:name=android.permission.READ_SYNC_STATS /

are these specific to sdk level 5?

Ideally, we could include these for level 3 and 4 users, and they just
won't be shown the contact sync option at all. Is this how it's meant
to work?

Thanks

[android-developers] Image viewers on android phones not always the best experience?

2010-07-15 Thread Mark Wyszomierski

Hi,

I'm trying to use an image-display intent to..display an image:

Uri uri = ...;
Intent intent = new Intent(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(uri, image/ + extension);
startActivity(intent);

this works well, but some devices have image viewers that handle this
intent which are sub-optimal. For example, on the Nexus One, it looks
like an image gallery application starts up - this takes about 10+
seconds before showing the image. On the Droid, an image application
starts up very quickly and shows the image right away.

If we shouldn't rely on the above intent to provide a good experience
for the user, is there another method anyone is using? Would just like
to know before I try writing something myself,

Thanks

[android-developers] Making a jar of an android project for use by third party apps?

2010-06-15 Thread Mark Wyszomierski

Hi,

I've made an activity which uses some image resources. I'd like to
make it available to other projects by packaging it as a jar. The
project is opensource - the goal of making it a jar would just be
convenience for the end developer.

I'm not sure that this is possible though - since the jar is being
created at the top level of my project's directory structure, it will
include all resources like string.xml, icon.png, etc. The projects
that import my jar will likely have resources with the same names,
which will probably be a problem since android resources aren't
namespaced, if I understand correctly.

Is there a way to export custom-made activities/views which need to
internally reference their own set of resources?

Thanks

 I set up some tech for this as part of the Android Parcel Project:

 Also, the current version of _The Busy Coder's Guide to Advanced

[android-developers] Anyone using the new facebook sdk for android?

2010-06-10 Thread Mark Wyszomierski

Hi,

Anyone try using the facebook sdk for android?:

  http://github.com/facebook/facebook-android-sdk

there are a few problems with it, most frustrating is that they're not
managing the login dialog correctly - rotating the device will hide
the dialog and leak it, sigh.

I was going to repackage it with correct management, just wondering if
anyone else has done it before I try. Also wondering if anyone has a
decent way of contacting the fb developers about it so at least the
patch could be reused, if I make it,

[android-developers] App not showing up for Evo users?

2010-06-08 Thread Mark Wyszomierski

Hi,

I'm working on a project (Foursquare). I pushed a new version to
marketplace last night, but it is not showing up in marketplace
searches for Evo users. I've read about this happening to other apps,
and one major reason seems to be if copy protection is being used (but
it is not for the Foursquare app).

Anyone else have an idea why this is happening? Is there a set of
permissions Evo doesn't support which may be blocking the app from
showing up in marketplace?

I can confirm your EVO problem, on both the old and new firmware (Sprint
pushed me an update just as I was looking at your problem).

The Market has apparently been acting a little odd recently, so your
issues may stem from that. Foursquare is a big enough name that you
hopefully have some contacts within Google that you can leverage to
figure out what is going on.

Hi,

If I do:

   for (int i = 0; i  3; i++) {

I'll get three notification icons on the notification bar, and three
list items in the pull down. Is there a way to use only one icon on
the notification bar, but still keep three entries in the pull down? I
tried doing:

   for (int i = 0; i  3; i++) {
   if (i  0) {
   notification.number = -1;
   }
   NotificationManager.notify(i, notification);
   }

but no luck. The docs say that setting notification.number to zero or
a negative # will prevent it from showing up on the notifications bar,

If I understand your question correctly, then yes.

In your manifest, just set the following:

android:targetSdkVersion=6 /

the app will still work on 1.5+. Just make sure you don't use any SDK
methods that don't exist on earlier platforms without checking the
user's local sdk version.

[android-developers] Finding a google business page?

if I have a name of a business, like John's Pizza Place, is there a

[android-developers] setContentView() twice on an activity?

2010-04-14 Thread Mark Wyszomierski

Hi,

What is the effect of calling setContentView() in an activity twice?
My situation:

  class A extends Activity {
  protected TextView mLabel;

  public void onCreate() {
  super.onCreate();
  setContentView(R.layout.a);

  mLabel = (TextView)findViewById(R.id.label);
  }
  }

  class B extends A {
  protected ImageView mImageView;

  public void onCreate() {
  super.onCreate();
  setContentView(R.layout.b);

  mImageView = (ImageView)findViewById(R.id.photo);
  mLabel.setText(hello);
  }
  }

this works, but not sure if it's ok to do this. Basically the parent
activity initializes a bunch of stuff that B will use too, B just
wants to add an additional ImageView for itself. So layout.a and
layout.b are the same, they're a copy-paste of one another. B just has
an extra ImageView appended.

[android-developers] Simple bluetooth presence detection?

2010-04-12 Thread Mark Wyszomierski

Hi,

Really general, very new to bluetooth. Can we have one android device
broadcasting a simple 'hello' bluetooth network (maybe a radius of
just a few feet) - then when other android devices come into that
area, reply with a 'hello' back? The client devices moving through the
'hello' radius wouldn't need to be always be checking for presence.
I'd let the user open an app and check for bluetooth networks nearby.
If they find one of these hubs, they can then choose to broadcast back
a hello.

Is that at all possible? Any general info would be great,

up with to indicate to users that a row has this capability,

Thanks

 I'm not aware of any hints for this.

 IMHO, long-click should be a power user thing. Make sure anything that
 can be done by that mechanism can be done by some other means that is
 more discoverable.

 For example, in the Contacts app, you can long-tap to delete a contact,
 but you can also tap on the contact, bring up the contact details
 activity, and do a delete from the option menu. The option menu is a bit
 more discoverable because there's a button for it.

[android-developers] How to indicate to user that a row is long-clickable?

2010-03-23 Thread Mark Wyszomierski

Hi,

I have a ListView. I let the user perform some action on a long-click
(pop up a picker dialog with a few choices) on row items.

Is there any typical UI mechanism that should be used to let the user
know that they can long-click a row item? Right now I feel like users
would have no idea to long-click the rows for a list of choices.

Thanks

[android-developers] Is app's first run?

Hi,

Is there any way to tell whether an application is being run for the
first time, other than checking if there are any left over
preferences / files from a previous run?

Thanks

[android-developers] Re: Is app's first run?

 Otherwise, checking for files/databases/preferences is pretty typical AFAIK.

This sounds like my best bet - so you're saying at app startup, I can
check if files/databases/preferences exists - if it does, this is not
my first run, if it is missing, then it's my first run?

Thanks

 While your app can't receive a broadcast Intent saying it was installed,
 I think you can receive one saying you were updated, if that helps.

 Otherwise, checking for files/databases/preferences is pretty typical AFAIK.

[android-developers] Re: Is app's first run?

Yeah that definition is perfect, having a little trouble implementing
it though.

I'm just trying to use:

  File file = getFilesDir();

this points to:

  /data/data/com.foo.bar/files

which is empty though, nothing gets written there during my app's
lifetime. My app's directory structure looks like this:

  com/foo.bar
/cache
/databases
   webviewstuff.db
/files
/lib
/shared_prefs
   com.foo.bar_preferences.xml

should I be seeing databases/preferences? Or am I supposed to be
looking for the existence of /shared_prefs/
com.foo.bar_preferences.xml. If so, is there a proper way to resolve
that path other than kind of hard-coding it into my app?

Thank you

 For a sufficiently-generous definition of first run, yes.

 You will not be able to distinguish between install and
 install-uninstall-reinstall this way. Hopefully, that distinction does
 not matter.

[android-developers] Re: Is app's first run?

Yeah that works perfectly, in my situation I'm working on an existing
project that is already in the wild, so I can't rely on a value in the
preferences file to check for this though. That would be the best
solution I think.

To get around this, I can do something like the following (going off
your original solution):

  File file = new File(/data/data/com.foo.bar/shared_prefs/
com.foo.bar_preferences.xml);
  if (file.exists()) {
...
  }

that is one big hard-coded string, but the existence of this file
seems to work ok. I guess it's alright?

Thanks

 If you have shared preferences, then you can do this:

 Step #1: Get your shared preferences (hopefully
 PreferenceManager.getDefaultSharedPreferences())

 Step #2: Look for the hey! I've been run before preference

 Step #2a: If that preference is not found, it's your first run, so set
 that preference (and commit() the change) and do your first-run logic

 Step #2b: If that preference is found, you've been run before,
 so...ummm...carry on, or whatever

[android-developers] Show activity on search button press?

2010-03-16 Thread Mark Wyszomierski

Hi,

Is there a way to launch an activity when the device's search key is
pressed?

I know we can hook into the search feature of android instead.

But I'm trying to fix a  broken app quickly. Ideally whenever the
search key is pressed (if my app is visible) then one of my activities
is started.

Thanks

[android-developers] Restarting an activity within a tab (TabActivity)

2010-03-13 Thread Mark Wyszomierski

Hi,

I have a TabActivity, each tab holds an activity. At some point I'd
like to 'refresh' the tabs. I'd basically like to restart each
activity in the tabs. I'm not sure how to do this. Calling:

   getTabHost().clearTabs();

removes the tabs, but the activities still seem to be in alive, in
limbo. How can I get them to really quit?

Thanks

[android-developers] Forward activity resultCode?

Hi,

Is it possible to forward a result like the following?:

ActivityA
   startActivityForResult(intentB, 22);

ActivityB
   startActivityForResult(intentC, 22);
   finish();

ActivityC
   setResult(99);
   finish();

is it possible to get A's onActivityResult() to fire here and catch
the value 99 as the resultCode? B excuses itself from the stack, so
really A becomes the parent of C in this scenario.

Thanks

[android-developers] Re: Forward activity resultCode?

That's perfect, thanks Dianne. This is how it looks now for reference:

ActivityA
   startActivityForResult(intentB, 22);

ActivityB
   intentC.addFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
   startActivity(intentC);
   finish();

ActivityC
   setResult(99);
   finish();

I just had to modify ActivityB's call from startActivityForResult() to
startActivity() otherwise it throws an exception since that flag is
specified on the intent, but the error message is very descriptive and
excellent,

Thanks

[android-developers] Supplying a different background drawable for a dialog?

Hi,

I'm trying to supply my own background drawable for a dialog. It works
fine on 1.6+, on 1.5 though instead of a transparent dimmed background
around the dialog, I just get opaque black. I defined the style like
this in my styles.xml file:

   style name=CustomDlg parent=@android:style/Theme.Dialog
 item name=android:windowBackground@drawable/my_background/
item
   /style

Is there something else we need to do so that we can still get the
transparency around the dialog? The drawable is nothing special, I
just took the stock one from the aop and changed the color on the
inside of the frame.

Thanks
