[android-developers] Seeding a Picasso Image Cache

[Evan Ruff]

Hey Guys,

I was wondering if anyone had any information, examples or tips about how to 
seed the Picasso image cache. I'd like to include a number of images in an 
asset bundle then load those into the Picasso Cache so that I can seamlessly 
download/dispay all the images without having to create my own LRU Cache and 
such.

I understand that the library uses HTTPCache, but I'm just not clear on how to 
add additional images.

Thanks for any help!

[android-developers] Nexus 5 Compatibility

[Evan Ruff]

Hey Guys,

Just updated my application and noticed that the Nexus 5 isn't on the list 
of compatible devices. Could someone point me in the direction of what 
changes I need to make to the manifest to get it to show up?

Thanks,

[android-developers] Multi-Page Form with Fragments and Tabs

[Evan Ruff]

Hey guys,

I was hoping someone could give me a little insight as to how I can make my 
multi-page form work a little better. Currently, each page (two pages) on 
my form is a separate fragment. I use the ActionBar Tabs to display the 
pages and then a Next button in each page that switches the tabs to the 
next page. All validation is done on the "Save" button on the last page. 

Everything is working well, but I'm having a little issue with the back 
functionality. I'd like to be able to create/pop back stack activities when 
the user switched. As it is now, he just gets tossed completely out of the 
wizard, not returned to the previous page (tab).

How should I handle that? Any input would be appreciated! 

Oh, I'm targeting API 14.

Thanks!

Evan

[android-developers] Android <> AppEngine SSL Weirdness

[Evan Ruff]

Hey guys,

I was wondering if anyone had been experiencing intermittent exceptions 
when securely connecting to an AppEngine servlet through 
the DefaultHttpClient? I've occasionally been getting execptions about 
certificates, closed connections, host unknown, etc... but only sometimes. 
I am using the -dot- notation, so I don't think that this error is related 
to my endpoint URL specifically. A sample of the exceptions are:

org.apache.http.conn.HttpHostConnectException: Connection to 
https://engine004-dot-myapplication.appspot.com refused
at 
org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:183)
at 
org.apache.http.impl.conn.AbstractPoolEntry.open(AbstractPoolEntry.java:164)
at 
org.apache.http.impl.conn.AbstractPooledConnAdapter.open(AbstractPooledConnAdapter.java:119)
...
Caused by: java.net.SocketException: failed to connect to /173.194.77.141 
(port 443) after 15000ms: isConnected failed: EHOSTUNREACH (No route to 
host)
at libcore.io.IoBridge.isConnected(IoBridge.java:230)
at libcore.io.IoBridge.connectErrno(IoBridge.java:161)
at libcore.io.IoBridge.connect(IoBridge.java:112)
...

and

javax.net.ssl.SSLPeerUnverifiedException: No peer certificate
at 
org.apache.harmony.xnet.provider.jsse.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:137)
at 
org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:93)
at 
org.apache.http.conn.ssl.SSLSocketFactory.createSocket(SSLSocketFactory.java:381)
...

I initially just assumed that there was an issue with the phone 
connectivity, but now with this peer certificate issue I'm not so sure 
anymore.

Does anyone have any ideas or suggestsions?

Thanks!

E

Re: [android-developers] Re: Bad View Behavior with Changing ListViews

[Evan Ruff]

Guys,

Thanks so much for your suggestions. I had tried all of the notify* and
invalidate* methods on the adapter and list to no avail. The easiest
solution for me was removing the swapCursor( null ) call. After doing this,
the "orphaned" views no longer persist and everything is working as
expected.

Thanks guys!

[android-developers] Bad View Behavior with Changing ListViews

[Evan Ruff]

Hey guys,

I'm having some funny issues with my ListViews. Generally, I have a 
ListView activity where the list view takes up the entire activity. The 
list views are using a custom SimpleCursorAdapter and are using the 
supportLoaderManager to load in the data. The Loaders are connected to 
Observers and the data can be changed by background services. I'm getting 
some weird behavior when the data changes.

When the data changes, I am doing an adapter.swapCursor( null ) while the 
new data is loading.

When the list gets shorter, I'm getting black areas where the previous 
views where, and sometime I'm getting ~ghosting of older views if the 
removed views are at the bottom of the list. Is there some way to enforce 
invalidation or removal of these views?

Is there some step I'm missing?

Thanks!

[android-developers] Starting with Loaders, Beginner Questions

[Evan Ruff]

Hey guys,

I'm beginning to bring my application out of the dark ages (API 7) up to 
the more recent stuff and I'd like to migrate from my current Singleton 
data provider to something like the Loader paradigm. I had a couple of 
question. Currently, when the Application starts, I pull all of my objects 
out of the database and hold them in a singleton User object on the 
Application. The Activities then pass around ID references which query the 
singleton for values. This breaks down rather dramatically when the 
application is terminated and doesn't really jive well with "the Android 
way." I've started to do some testing with loaders and have based my test 
implementation off the follow tutorial:

http://www.androiddesignpatterns.com/2012/08/implementing-loaders.html

Couple Questions:
1. Are loaders special? Are they handled differently from a LifeCycle 
perspective or is it simply a more streamlined way of doing loading in an 
AsyncTask then returning it to the Activity?

2. There always seems to be a nasty flash of an empty list on my 
Activities. Should the onResume check for a load and load immediately? 
(deliverResults?)

3. Do the loaders save state in an onSaveInstanceState sort of way?

4. I'm a little foggy on the ContentObserver. My data is backed up by the 
SQLlite DB... is a ContentObserver "better", or should I just manually 
invoke BroadcastReceivers when my application pulls down new data?

5. How should I handle loading animations in the Activity? Traditional way 
of start/stopping the "Loading" animation? My question is around when... 
show ProgressBar in onResume and hide it on onLoadFinished?

Thanks for any pointers!

[android-developers] Re: Launch Behavior Issues, 2.3 vs. 4

[Evan Ruff]

Hey Guys,

So I have discovered what was creating this behavior.

Basically, in my activity, I reuse the calling activity to relaunch the 
activity based on a number of parameters. By changing the action of the 
intent, it fools the system into thinking that the LAUNCH activity is gone. 
This was causing the system to recreate the task each time you hit the HOME 
icon, as the intents didn't match and that was that.

To fix the problem, I moved all the Intent based signalling (which we weird 
anyways) into my saved state object and now we're humming along nicely.

I really appreciate all the help from the group! I thought I had checked 
everything but everyone's input helped me really zero in and fix the issue.

Thanks guys!

And... I spoke too soon.

When I exported the application and installed it on the device, it goes 
back to the wonky launch behavior...

Re: [android-developers] Launch Behavior Issues, 2.3 vs. 4

[Evan Ruff]

So I found an edge case where I was calling finish() on my Launcher 
activity. This was causing the behavior I described above.

I'm still not sure why it's different for the emulator and for the actual 
running, but preliminary testing has indicated that it solves the issue... 
so far so good, will report back with findings if anything changes.

Hey Kostya,

Thanks for the reply. 

What are the differences in these flag?

Do you have any insight into how to make the production app perform the 
same Home <> Launcher behvior as when it's production?

Thanks,

[android-developers] Launch Behavior Issues, 2.3 vs. 4

[Evan Ruff]

Hello all,

I'm having some very frustrating and confusing issues getting my 
application to function as it has been. My application uses an Application 
object to hold a user object. This object is large and is loaded from the 
database and held in the Application singleton (MyApplication extends 
Application) by an async task in my .Splash activity. All activities 
subclass a BaseActivity that checks for the existence of this user. If the 
user is not present, it finish()es the activity and finishes all the way 
back to the Splash screen, where the user is loaded from the DB.

The splash activity looks like this:








This application has been deployed in various forms all the way since 1.5. 
In the past, let's say you were working in the application on an Activity 
four down the stack. You hit home/phone call/whatever and, when the 
application returns, the onResume activity picks up the user from the 
Application and everything works as normal. I am not getting this behavior 
anymore. On my MyTouch running 1.6, it works as expected. Whatever Activity 
was previously on top of the stack is loaded and onResume called.

All of a sudden, I am not seeing that behavior.

On my Galaxy Nexus, it does not work as expected. On the GNexus, if I hit 
HOME then hit the Launcher icon, sometimes, the Application is clobbered 
and the fall through happens. Other times, it goes right back to the 
launcher .Splash activity. If I hit HOME, then hit the recent apps, it 
works fine. Looking at LogCat output, it doesn't seem to try to resume at 
all if I hit the Launcher button.  I have tried launchMode=singleTop, but 
that doesn't seem to work.

And here's even the crazier part... if I deploy the application from the 
debugger over ADB... WITHOUT ANY CODE CHANGES, I get the behavior I'm 
expecting and have gotten in the past. The last activity pops up as usual, 
onResume executed and the application can find the Application. This holds 
true even if I disconnect the debugger, restart the phone, and just use the 
application that way. The problem occurs when I compile, deploy and install 
the APK directly.

I'm quite baffled by this behavior. Has anyone else had this sort of 
scenario?

I'd appreciate any help anyone could provide.

Thanks!

Evan

Re: [android-developers] Re: Transporting to Server Problems

[Evan Ruff]

Right, the thing is, I NEVER get the the problem when I'm testing. It's
only happening in the field.

What's really weird is that it's just not THAT much data. I mean, I'd say
the average payload size is <200kb!

Thanks!

[android-developers] Transporting to Server Problems

[Evan Ruff]

Hey guys,

I'm having some trouble getting my phone collected data up to my servers. I 
thought that I was getting old fashioned SocketTimeouts due to the phones 
having a bad connection or something of the like. After jacking up the 
timeouts WAY up on the phone (120 seconds) and the timeout WAY up on the 
server (120 seconds) I think that I must be doing something wrong in my 
code.

After changing the timeouts, I am now getting other odd timeout exceptions 
on the server. I'm getting a variety of "Unexpected EOF read on the 
socket", "java.io.IOException: Invalid CRLF" and the venerable 
"java.net.SocketTimeoutException". I'm wondering if I'm not properly 
flushing or clearing out the connection/entity in the Service logic. I was 
hoping someone could point out what I was doing wrong.

My data-sending code is as follows:
DefaultHttpClient httpClient = Util.getHttpClient(); // nothing special, 
just sets the timeouts

HttpPost httpPost = new HttpPost( Moose.getServerAddress() );
ByteArrayOutputStream baos = new ByteArrayOutputStream();

*// Write out the payload using Jackson to the baos*

ByteArrayEntity baEntity = new ByteArrayEntity( baos.toByteArray() );
baEntity.setContentType("application/json"); 
baEntity.setChunked( true );
httpPost.setEntity( baEntity );

HttpResponse response = httpClient.execute( httpPost );
HttpEntity entity = response.getEntity(); 

I'm not doing any cleanup at all, and I think that might be my problem. Is 
there a correct way to terminate this off? I assume I should be closing 
the  ByteArrayOutputStream, but what about the ByteArrayEntity? Do I need 
to do anything with the response after I'm doing consuming it?

Thanks for any help and suggestions!

[android-developers] Spinner Styling - Am I Nuts??

[Evan Ruff]

Hey guys!

I have a spinner backed up by an ArrayAdapter in my layout. I'd like to 
change the look of the spinner button to match the buttons that are next to 
it.

Here is my Spinner xml:


While the bounds of the button (it fills the width/height/weight correctly) 
and the background work, the text is larger and the gravity is not centered.

I'm going nuts trying to fix this! What am I missing? Is there a different 
style I need to use or something like that?

Thanks!

[android-developers] JAVA_HOME Not recognized in Tools?

[Evan Ruff]

Hey guys,

Not to sound like a grump, but why does \tools\lib\find_java.bat ignore the 
JAVA_HOME environmental variable? I have having to change my config around 
just to reference this.

[Evan Ruff]

Thanks Xavier. I'll just deal with the open/close/open until then, it's no
too bad now that I've reduced the number of platforms.

Re: [android-developers] Development Tools Crashing

[Evan Ruff]

Also, not sure if I tried this previously, but it seems that now I can get
the layout editor if I close the opened XML tab, wait a minute, then reopen.
I still get the "No theme selected" message, but after selecting one it does
render properly!

Re: [android-developers] Development Tools Crashing

Kostya,

I followed your instructions to update Eclipse and it has fixed my content
assist issue! Thank you for the great tip!

Xavier, I have removed all of my unused Platforms and now only have 1.6 and
2.1 with the Google APIs. I have confirmed I can recreate the NPE issue. I
am installing the new version with the debug now...

Tor,

I'll install this tonight and test. I assume I drop the "plugins" folder
into my Eclipse installation.

I apologize for my naivete, but I've become stupid reliant on the Plug-in

Seni,

Re: [android-developers] Re: Development Tools Crashing

[Evan Ruff]

Xav,

I have, ~all the targets since 1.0 installed! Maybe this is breaking
everything?

I'll remove everything except 1.6 and see if that helps.

Also, is there a new version (you mention ADT 10.0). I'm on 9.0, but the
Update Manager does not inform me of anything?

Thanks for the help!

[android-developers] Development Tools Crashing

[Evan Ruff]

Hey Guys,

I'm having a NPE thrown when I try to edit a layout. I generally happens 
about 85% of the time. If it does not throw the NPE, it says "Missing Theme" 
with no assist or layout. The XML editor does still provide assistance if 
the NPE is not thrown. Additionally, my auto-complete is taking FOREVER 
inside Android classes. Is anyone else experiencing something like this? Any 
ideas how to rectify the situation?

Thank you for any help!

Evan

Here's the details:
Eclipse Helios R1, 32-bit Windows installed on Drive E. Projects/Workspace

Subversion, etc... everything else is pretty stock.

In my Content Assist preferences, I only have Basic Proposals and Java

[android-developers] Help with GridView, ImageAdapter and Custom Drawable

[Evan Ruff]

Hey guys,

This is my first stab at programmable graphics on Android and I'm
running into some LifeCycle issues (I think). If any of the gurus on
the board could point me in the right direction, I'd appreciate it.
Here's the scenario:

1. Dialog box that contains a GridView.
2. GridView contains an ImageAdapter (extends BaseAdapter)
3. ImageAdapter contains an ImageView, which is returned on getView,
handing the recycling based on the convertView parameter. It's about
95% of the 
http://developer.android.com/resources/tutorials/views/hello-gallery.html
ImageAdapter.
4. The ImageView is either an ImageResource or an ImageDrawable. If
the ImageResource for the given element is available, it uses that. If
not, it constructs a custom Drawable that's a filled rectangle with
the name of the element in text.

I recently added the custom drawable portion, so I believe that's part
of my issue, as it was working previously.

The behavior I'm seeing is that when the Dialog is 1st displayed,
everyhting happens as expected; however, when I close the dialog and
open it back up, the application crashes with the following stack:


java.lang.NullPointerException

at dalvik.system.NativeStart.main(Native Method)


The getView method looks like this:


public View getView( int position, View convertView, ViewGroup
parent )
{
if (convertView == null)
{ // if it's not recycled, initialize some attributes
imageView = new ImageView( mContext );
imageView.setLayoutParams( new GridView.LayoutParams( 
thumbHeightPx,
thumbWidthPx ) );
imageView.setScaleType( ImageView.ScaleType.CENTER_CROP );

imageView.setBackgroundResource( R.drawable.acc_brand_select_background );
}
else
{
imageView = (ImageView) convertView;
}

Brand theBrand = Moose.getUser().getBrandList().get( position );
BrandType type =
BrandResourceDictionary.getBrandById( theBrand.getId() );

if( type == null )
{
BrandThumbnail brandThumb = new BrandThumbnail( theBrand );
imageView.setImageDrawable( brandThumb );
imageView.setOnClickListener( new
BrandImageClick( theBrand.getId() ) );
}
else
{
imageView.setImageResource( type.getThumbResource() );
imageView.setOnClickListener( new BrandImageClick( type.getId() 
) );
}

if (position < imageViewList.size())
{
imageViewList.set( position, this );
}
else
{
imageViewList.add( this );
}

return imageView;
}


With the error coming on line 154: imageView = new
ImageView( mContext ); (Line 5 in the pasted code above)

Why does it crash when displaying the second time? Am I fundamentally
missing a part of the lifecycle of this object? Any other advice you
can give me?

Thanks for reading throgh the post! I really appreciate any help I can
get!

Thanks,

Evan Ruff, Atlanta

[android-developers] Re: ADT Crashing Constantly - Background Image Related

[Evan Ruff]

I'm on ADT 0.9.7.v2010050711...

Eclipse 3.5 EE SR2, specifically build 20100218-1602.

If I have a tiled pattern, all I get is a black background. If doing a
gradient fill in the background, I also get a blank black background.

For instance, here is a text view with a @drawable background:
http://schemas.android.com/apk/res/android";
android:id="@+id/title" android:gravity="center"
android:layout_width="fill_parent" android:layout_height="40dp"
android:background="@drawable/app_header_background_gradient"
android:text="QSA Checkout" android:textStyle="bold"
android:textSize="22dp" android:textColor="#"
android:shadowColor="#FF00"
android:shadowDx=".5"
android:shadowDy=".5"
android:shadowRadius="2"
android:typeface="serif"
/>

and the drawable:

http://schemas.android.com/apk/res/android";
android:shape="rectangle">



Which is not displayed at all in the layout view.

[android-developers] ADT Crashing Constantly - Background Image Related

[Evan Ruff]

Hey guys,

I don't know if this is the right group, but my ADT keeps crashing
while editing layout files. I'm not positive, but I think it might
have something to do with the background images that I'm attempting to
use, as they are not rendered in the preview at all. Is this the
appropriate group to discuss the ADT tools? If so, does anyone else
have problems getting background images to display?

Thanks!

[android-developers] Eclipse Helios running SLOW

[Evan Ruff]

Hey guys,

Just upgraded to 3.6 after this whole Sun/Oracle JVM fix/debacle and I
notices that 3.6 EE runs super, duper slow. So slow to the point that
code assist is unusable. Here are some changes I made to the config to
make it operate a lot better:

eclipse.ini: replace the end with this:
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=512m
-Xms128m
-Xmx1024m

And turn off JAX-WS Proposals in Content Assist
Window > Preferences > Java > Editor > Content Assist > Advanced

I also disabled JPA and PDE, but you might need them depending on what
you're doing.

Hope this helps,

Evan

[android-developers] More about WakeLocks and Services

[Evan Ruff]

Hey all,

I was wondering if someone could help me clarify how I can created the
following:

1. My application uses AlarmManager to trigger an IntentService
2. IntentService gets a WakeLock
3. IntentService runs all the necessary code
4. IntentService releases WakeLock

For an IntentService, Is there a way to accomplish this without using
the BroadcastReciever Pattern, as created by Mark Murphy? It's my
understanding that the AlarmManager will invoke the Service directly,
so can I get a valid wake lock inside of the onHandleIntent method?

Thanks!

[android-developers] Extended Resources Strategy

[Evan Ruff]

Hey guy,

I was wondering if some of the experts out there could help me with an
extended resource strategy? I'm interested to hear about some of the
accepted best practices that everyone is using to tackle some of the
issues that arise when you've got a ton of graphics/resources.

I just recently upgraded all the resources in my application to have
separate hdpi and mdpi graphics. After struggling with and figuring
out the dpi-based methodology that android employs I have to say that
I'm very impressed with the design. The application looks absolutely
fantastic and renders great on a number of devices. Really not that
much additional coding once you get it all figured out. The problem I
have now is that my application is over 4mb.

The application is heavily PNG driven and, even after punypng*
optimizing everything, it is still a huge amount of graphics. There
are over 150 different icons and headers used in the application. When
you add another set for high resolution, you're looking at over 300
images that drive the user experience. Currently, everything is thrown
in the /res folder and managed from there through a lookup dictionary.
Functionally it works 100%, but I'm worried about the massive amount
of transfer time when people upgrade.

Has anyone tried breaking out the images and then downloading those
separately from the main application? What I'd like to do is publish
the APK to the market and have it managed as usual. Then, depending on
the device, I'd like to go to an S3 store and download a ZIP of the
graphics. Once the download was complete (1.3mb for hdpi, 500k for
mdpi) I would like to move the graphics to the storage card and unzip
them there, referencing them from the main application on the card.

Is this a good strategy? Am I missing anything regarding the auto-
scaling and such? Other than the various synchronization issues does
anyone see any problems with this approach? Would there be a
noticeable performance hit loading the graphics from the SD Card as
opposed to memory? Does Android include native zip/unzip libraries?

Thanks for all your help and input!

[android-developers] Prevent view from scaling background

[Evan Ruff]

Hey guys,

I've got a quick question that I can't seem to find the answer too. I
have a LinearLayout with fill_parent for both height and width. I set
the background to a hires image that is 480x855 in case I encounter a
long device. When it goes to put the imagine in the background for
both the ADP1 and the Droid devices, it ends up squishing the imagine
down when I'd prefer to just maintain the aspect ratio and crop.

Is there a way I can accomplish that? I've tried adding
scaleType="center" and "fitStart" but it seems to want to squish it
every time. Is there a way I can just line it up at the top?

Thanks!

Evan

[android-developers] Screen Sizes with 1.5, 1.6 and 2.0

[Evan Ruff]

Hey guys,

I've got a quick question about screen size support. Currently, I've
got an application that is rockin' along just fine on 1.5 and 1.6.
Today the client called and says they want to run on Droid. While I've
downloaded the 2.0 SDK, I'm a little wary of compiling against it.
Will it break 1.5 and 1.6 compatilbility? How will the "medium" phones
(G1, MyTouch) know to use those layouts?

I imagine this is a pretty rudimentary question so if it's in a doc
somewhere, can someone point me in the right direction?

Thanks!

[android-developers] Re: Widget Layout Frustration

[Evan Ruff]

I hope it doesn't sounds like I'm being argumentative, but, I mean,
REALLY? That's like saying "We reserve the right to an Icon with Text
on the home screen."

FWIW, some of my favorite home screen widgets are the Bluetooth Toggle
guy and the Calendar tCalendar widget. They do EXACTLY what they say
and don't take up any more than the minimum space; additionally, they
maintain an heterogeneous look on my home screen, which really helps
with my OCD! :-)

[android-developers] Re: Widget Layout Frustration

[Evan Ruff]

RG,

My widget manages the state of a Service running in the background. As
you click the widget it starts/stops/pauses/etc the service. I want it
to look like a Shortcut so that it fits into the Home Screen
seamlessly. Additionally, the icon and text change depending on the
state of the service. Is there a way to do that using a shortcut
without going with a widget? Otherwise, can you think of another way
to use the OS-level resources to render the same sort of thing?

Thanks!

Evan

[android-developers] Re: manually update AppWidgetProvider's onUpdate

[Evan Ruff]

I don't know if this is EXACTLY kosher, but I've overriden the
onRecieve method in my AppWidgetProvider to look like:

@Override
public void onReceive( Context context, Intent intent )
{
this.view = new RemoteViews( context.getPackageName(),
R.layout.widget );
if (intent.getAction().equals( MY_AWESOME_CUSTOM_INTENT ))
{
// DO AWESOME STUFF HERE
}
else
{
super.onReceive( context, intent );
}

ComponentName me = new ComponentName( context, VAWidget.class );
AppWidgetManager.getInstance( context ).updateAppWidget( me,
view );
}

Then I just add the custom intents to the widget's intent-filter in
the manifest as usual.

It has worked every time for me, but I'm wondering if there is a
scenario where it would not be preferable to do it this way?

Susan,

I've tweaked it a little bit more and here is where I'm at:

http://i243.photobucket.com/albums/ff2/gte619n/widgetLayout.png

Pixel for Pixel, the text is exactly the same. The location within the
bounding box is the same, as is the distance between the text and the
graphic. In order to do this, I used the XML Layout and an XML
drawable, no 9-patch was necessary.

Here's the code:
res/drawable/text_border.xml
http://schemas.android.com/apk/res/android";>





res/layout/widget.xml

http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
>
http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"

Hope this helps!

[android-developers] Widget Layout Frustration

[Evan Ruff]

Hey Guys,

I was hoping someone could help me with a home screen widget I'm
trying to layout. Basically, I'm trying to layout my widget so it
matched a standard home screen application shortcut perfectly.
Basically, at this point, I'm about ~2px off and it's driving me
crazy! Has anyone gotten this to match up just right? Should I be
able to find this layout in the source somewhere? Any clues would be
much appreciated. Here's my layout thus far:

[android-developers] Re: Sending/Receiving Java Objects to Server

[Evan Ruff]

That's a great question and something that I'm wondering too. Perhaps
there is an optimized version available that only does the simple
encode/decode?

FWIW, the Jackson JSON mapper that I'm using currently weighs in at
397kb.

You know,

I would be awesome if we could get some sort of native C++ system
service to solve this issue. I don't really care WHAT the
implementation is, so long as it's blazing fast.

Is that even part of the Android thing?

[android-developers] Sending/Receiving Java Objects to Server

[Evan Ruff]

I have a Tomcat Server in front of a Servlet that gets/stores
information in a MySQL Database. My Android application needs to get/
put information on to this server. I control both ends of the
communication, so I've basically been exploring the "best" way to send
information back and forth. So far, I've tried Jackson for JSON and
the native Java Serialization packages. My object is relatively
complex and completely serializable. I have no desire to write a
"custom" guy at all, as I doubt I'd actually be able to improve on
most of the packages.

Times are from when the response lands on the Android device until the
Object is fully cast:

Jackson for JSON 1.0: 17.176 seconds.
Native Java Serialization: 36.132 seconds.

WOW. Java Serialization is a D-O-G.

So with that being said, are there any other strategies/packages I
should try to get information to/from my server?

Thanks!

[android-developers] Weird height of ScrollView

[Evan Ruff]

Hey guys,

I'm trying to build an interface and I'm having some trouble with the
ScrollView component. Basically, no matter what height I set the
ScrollView, it only renders 45px high. Even if I set the height to a
fixed pixel number (like, 200px) it still only renders into a tiny
area of the screen.

Generally, I've got a pair of tabs at the top, then the FrameLayout.
Inside of that, my first tab is a vertical LinearLayout, with a
horizontal LinearLayout holding small labels, then a ScrollView with a
ListView inside of that. The FrameLayout appears to be rendering the
full height, as my second tab fills the space as you would expect.

Here is the XML:

http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">





http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">


http://schemas.android.com/apk/res/android";
android:id="@+id/listByPackage"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:drawSelectorOnTop="false"
/>









also, here is the included review_collection_header layout:

http://schemas.android.com/apk/res/android";>







Can anyone shed some light on what could be happening here?

Thanks a lot!

[android-developers] MyLocationOverlay and enableMyLocation()

[Evan Ruff]

Hey Guys,

I've got a bit of a weird issue here.

In my activity, I've got MyLocationOverlay on top of my map and
enableMyLocation() in my onResume function. Funny thing is that when I
go to run the app in debug, enableMyLocation() returns false. I'm
targeting the Google Platform, and my Google Maps application
successfully takes location data from DDMS.

Can anybody think of a reason why enableMyLocation() would always
return false?

Thanks!

[android-developers] ListView and Selectors

[Evan Ruff]

Hey Guys,

After going through a bunch of posts here I've got a List Activity
with a pair of custom selectors that do the alternating row background
thing while maintaining the default selector behavior! The trick was
figuring out that in the selector, you had to fire a shape in there
instead of a plain android:background tag!

Looking to further extend the function, I was wondering if there is a
way to get the same sort of long-press/fading effect that the default
Google Applications have. For instance, when you long press an SMS in
the Messaging application, it kinda fades from the orange to white. Is
that possible to implement in a standardized fashion?

Thanks for any tips!

[android-developers] Some Basic Questions

[Evan Ruff]

Hey guys,

I'm just starting to refine my first Android application and I was
wondering if you could help me with a couple of general issues I'm
having.

1. State

Honestly, I haven't really done too much research here except for
looking at the Activity/SubActivity stuff (that's how most of my
interaction is driven) within the google dev sight. Basically, I was
wondering if anyone had a reference to a good article/tutorial about
how to manage the state of the application when I user exits, hits
'home', answers a call, etc. Currently, my app pops all the way out to
my main activity whenever the user moves from the app.

2. Activity Lifecycle

I'm also a little confused with how the Activities get used/recycled.
It seems like every time I call an activity it calls onCreate, no
matter what, even if the activity has already been created or is
static. Is there a way to "hide" activities instead of reinflating
layouts every time something is called?

Thanks for all your help!

Evan

[android-developers] Webview: CSS Gradients vs Background Images

[Evan Ruff]

Hey guys,

I've got a general performance question. In my Webview app, I'm trying
to display a div (statically-sized) that is 100px x 200px. The div has
a linear gradient that goes the whole 200px. From a performance
standpoint, do you believe that it would be fastest to use an
optimized 1px image and tile the background, or to use the -webkit-
gradient function?

I'm really only asking because the "webkit-gradient" implementation
looks a little crappy to me. The gradient isn't "smooth" like it is in
Chrome,/Safari; it's extremely striated, like you'd get with a poorly
optimized .GIF, circa 1998. Would a tiled image degrade performance?

I like the idea of the CSS as I can change the size of the elements
easily for future phones, but I'm not sure if the visual hit is worth
it.

Thanks for any help!

[android-developers] Re: RPC Best Practices

[Evan Ruff]

Mark,

Thanks for your lightning fast response.

I've been living over in GWT land for the last year or so, so I guess
I've gotten spoiled. GWT's whole "object<->internet<->object" magic
has really taken me out of the transport game! I kinda got the feeling
that there were no real native packages that would run the mapping/
serialization/deseriazlition for me. Do you have any experience/
recommendation with any of the available libraries that do the mapping
automatically? I'm wondering if XStream, Json-lib Jackson JSON would
work in a compatible and performance-acceptable manner.

I know I sound like a baby and should just suck it up and write it
myself, but I'm trying to integrate my system in with a number of
existing POJOs and it would be VERY time consuming to have to write
the transporters for each one.

Thanks for your help!

Evan

[android-developers] RPC Best Practices

[Evan Ruff]

Hey guys,

I'm starting my first Android Application and I'm trying to figure out
the best way to implement an RPC layer to communicate with my Tomcat
server. Basically, I've got POJOs on the Android Client and on the
Server. I simply would like to serialize the POJOs on Android, send up
an HTTP Post, deserialize on the server, do some work, then serialize
a POJO response back down to the client.

I've seen a number of posts referencing JSON and XML but nothing
really definitive. Further clouding the matter is the different
Android SDKs out there that seem to have different levels of support
for each. Obviously, if Android has a native library that works well,
I'd like to use that. Additionally, I'd like something that could work
with my existing POJOs without a great deal of trouble.

What are the best practices for this sort of thing? Can anyone send me
to any tutorials that have some solid examples on how to get this
implemented and going?

[android-developers] Re: Location of Gears Local DB

[Evan Ruff]

I was afraid of that :-)!

In case anyone else is wondering, I was able to troubleshoot my issue
using the tools included in the standard gears SDK distro. There's a
database.html file in there that will let you run SQL against any
target. I used it to double check my DB.

[android-developers] Location of Gears Local DB

[Evan Ruff]

hey guys,

I was wondering if anyone could direct me to where Gears is putting
the local SQL Lite DBs.

I can't seem to find it mentioned in the documentation anywhere!

Thanks!

[android-developers] Re: Nightly Build for Emulator

[Evan Ruff]

Hey Al,

Sorry to bother you about this, but when I installed your package, I
can't seem to get any network access.

When I used the regular emulators, I get 3G without problem, but your
dist seems to say no connection. Any ideas?

Thanks!

[android-developers] Re: GWT and the Android Browser

[Evan Ruff]

JP,

Thanks for your response! I've downloaded 1.1_r1 and done a little bit
more testing and:

#5, #6. This is something that seems to ONLY happen on the Android
system. In Chrome it screams along like a scalded dog. Stuff pops up,
hides, fades etc like it was a native application.

#2. There's some work going on over in the GWT stack to have Gears/AIR/
HTML5 native storage/workers/caches abstracted in GWT. This is a
pretty exciting project and will hopefully lead to some truely awesome
android ports.

#4. Farts. Still there. Maybe a TICK faster, but not really.

#1. Still weird.

#3. ditto.

iPhone has implemented a mouse drag event framework that looks pretty
cool. No love for Android yet though. I'd love to try a nightly build,
but as I'm on Windows I can't do a image compilation from source.

[android-developers] Nightly Build for Emulator

[Evan Ruff]

Hey guys,

I'm a lame-o Windows developer trying to do some Browser specific
development targeting Android. I'm having some funny issues with my G1
and my older emulator (WebKit CSS/Layout, etc). I was wondering if any
of you Linux guys out there might be so kind as to give me a compiled
image of the latest nightly build? I believe I need three files out of
the tools directory:

/tools/lib/images/userdata.img
/tools/lib/images/system.img
/tools/lib/images/ramdisk.img

I'd build it myself, but my windows box can't do it!

Thanks!

Evan

[android-developers] GWT and the Android Browser

[Evan Ruff]

Hey guys,

Little stream of conciseness here, sorry if this is a bit long/
disjoined.

I was wondering if anyone had done any work with GWT and the Android
Browser. While I'm getting basic functionality to work, the general
speed, responsiveness and user experience seem very sluggish and,
well, sorta bad. Another issue I'm having is locating a group to go to
for support, examples and help. While I'm interested in GWT with
Android, it seems that Android Developers Group is really only
interested in native apps. Where to go for Browser specific help?

Anyways, some of the particulars I've run into:

What group to go to?

1. Issues Controlling the viewport: No matter what I do, I can't seem
to get proper control of the viewport. Editing the meta data, overflow
CSS properties, insuring that the window's objects are small, etc. I'm
continually getting white space borders and stuff like that. This
causes weird finger behavior, especially allowing the user to browse
into the white space.

2. HTML5/Gears Wrappers: I was wondering if the Gears API has an
implementation to support HTML5 storage/cache issues in case of a non-
gears enabled client. If not, is there a library anywhere that
supports the encapsulation for GWT?

3. MouseListeners: The OS seems to swallow up the MouseUp event in
order to do detection of scroll/drag type stuff. I guess I understand
why it does it for the drag type thing, but it never fires MouseUp
even after the drag is done. Ehh... fair enough, I guess.

4. Focus Panel ClickListeners: When I click a focus panel, a orange
circle shows up in the upper/left corner with what seems like a cursor
in it? (http://i243.photobucket.com/albums/ff2/gte619n/
selectBubble.png) Also seems like a non-trivial delay between the
press and then a following action. Makes the app seem especially
sluggish.

5. Image Loading/Display: Seems really slow. Even when doing
background repositioning to flip sprites. Additionally, the images
don't seem to load in any fixed order and method. Also seems to hang
when loading images (http://i243.photobucket.com/albums/ff2/gte619n/
selectBubble.png) I've attempted to get around this by doing Prefetch
and such, but nothing seems to work. Seems like it needs to talk
itself into refreshing the screen after loading finishes (even in
localhost in the emulator)

6. Visibility hide/show: Very sluggish in general.

7. Scroll inside divs: Flat out doesn't support this. I guess the
Cupcake release, bringing the browser up to Nov 2008 Webkit, should
fix this but I still don't have any visibility into that release.

Has anyone compiled some best practices to use when building an
Application for Android? Maybe even some widgets or JSNI breakouts to
better manage the behavior and performance of the app?

Thanks!

Evan

[android-developers] Web Browser stop Selection

[Evan Ruff]

Hello,

I am developing a GWT-based application to be used on the Android
Platform through the browser. The one big problem that I'm running
into is the hijacking of my "press-and-hold" methodology. Basically,
I've got an image that has a timer on it. When you press the button
the timer runs (onMouseDown), and then it cancels when you lift the
finger (onMouseUp).

The problem I am running into is that when you hold your finger down
on a button, the Android Browser pops the "View Image/Save Image"
dialog over everything, effectively killing my UI.

Is there a way to disable that functionality? I was thinking there was
a Webkit type css in there that would allow me to do it, but so far
I've been unsuccessful.

Thanks!

Evan
