[android-developers] Re: How to set the color of listView unused area in 2.3.3
Are you sure that area is part of your listview, and not the layout that contains it due to the list view height being determined by it's contents? I.e. I am not sure listview has any "unused area" If so, change the background color of layout containing the list view to match the list view color. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Offering free and paid APKs on the Market
Honestly, you'll probably do better to have a single .apk and use an in-app purchase to do the free to paid conversion. There was another thread on here that discussed this extensively.

I think it's mentioned somewhere in the docs, but can't seem to find the reference. So, basically, if you want to have two (or more) apps with a shared UID, you have to design for this in advance. E.g., release one app with sharedUserId="foo" and the next one with the same.

AFAIK, if finish() is called from onCreate(), the view is never shown.

[android-developers] Re: popupwindow
An interface is exactly just that (plus constant declerations). With abstract classes, you can have static methods and everything else that comes with a proper class. The drawback is, of course, that you can only inherit from at most one abstract class. I cannot think of even a single example, off the top of my head, where an abstract class in Android could have also been defined as an interface without losing any functionality.

[android-developers] Game not functioning properly after it is recreated by Android.
Hi, Yesterday I ported one of my windows games to Android. I used AndEngine. The game functions perfectly except when it is recreated by android. For example, you play for a while and then use the back button, open the browser, market and a couple of other apps and then come back to the game. The background and scoring system loads perfectly but the ball (which is sort of the entire game in itself) doesn't load or show!! Is there a bug with my code? Or is there a bug in AndEngine? Or both? Or none?

[android-developers] SharedUserId: Things that Cannot Change http://android-developers.blogspot.com/2011/06/things-that-cannot-change.html
Would SharedUserId be worth calling out. I currently don't have one set on any of my apps, but after playing around with the feature while trying to get a Test Project to run as the same user ... I think it's not really possible to change the user_id with a live app without some big issues. The only way I can think to do it is to release an apk which changes all elements in /data/data/* to be opened with Context.MODE_WORLD_WRITEABLE and then later in another apk release, change the sharedUserId to the value desired. This sounds pretty bad. My theory is based on just very primitive tests of upgrading from a debug build with no sharedUserId to a debug build of the same package (cert) and realizing that any attempt to read anything in the /data/data/ either throws a SecurityException or FileNotFoundException (even when writing a new file). I think this should really be called out in the documentation, similar to how package name has big bold letters around it all the time that says (DO NOT CHANGE!) :) However even with my idea of making a release with world writable files, I don't believe I would ever be able to create new files within /data/data/. I am wondering that if the package name has to be unique anyways for the package manager, why they just didn't make the default user_id the package_name of the app. Then with the correct signing cert and agreed upon name you would be able to migrate to a userid if need be. ...

[android-developers] Re: droid x2 install from unknown sources?
I uploaded another .apk to the web site and clicking on the apk link appeared to download but it didn't install. Looking around a bit I found awesomedrop on Android market. After installing it on the Droid x2, I activated it on the Android and then went to their web site at labs.dashwire.com . It created a key for me to enter into the android app. I then dragged the apk file that wouldn't install from the web link to the browser window and PC/Android combo proceeded to download and install the .apk file correctly. The answer at least on the Droid x2 is: you need some sort of app to do the installing for .apks not on Android Market even if "unknown sources" is checked.

[android-developers] Re: How to know what internal process runs an application
Thank you Mark for taking care to answer. I have already thought of implementing it the straightforward way you propose, but I think that this is not satisfactory, for the reasons I have attempted to expose in my previous post. I'm sorry, but your answer does not answer my requirements, and as I stated, having to insert a line of code referring a static method every where I need to make sure my application is initialized is for a poor design, because I have something like 100 Activity classes in my application (yes, this is a very big application), and I cannot prevent from forgetting to insert the piece of code somewhere. I prefer to have an interception design pattern, so as to circumvent that issue. I'd prefer not to have to derive from abstract classes neither. If someone is eager to accept my requirements and propose a solution, or simply state that there are no solution, I'd be very grateful. I still do not understand why the Android platform does not expose the "android:process" information at runtime when starting up a process, because this is something declared in the AndroidManifest.xml, and that it may provide valuable information for developers at runtime, event if, yes, I understood, an application process is just an anonymous container ;) In my opinion, it should not be that anonymous when you explicitly state a value in the manifest, and I do not expect to get the PID, just the declared "android:process" value, because this is not an implementation detail, this is a structural information.

[android-developers] A little help with layout params in code.
Hi All,
I am hoping someone out there can give me an idea what I am doing
wrong. I wanted to create a table dynamically in my application,
which I did, but also I wanted to be able to set some of the layout
parameters, specifically the gravity and layout_gravity for a couple
text views and one image view.
I thought it would be pretty straight forward and tried the following
code:
if (v.getId()==R.id.add_row) {
mRowCount++;
TableLayout table =
(TableLayout)findViewById(R.id.the_table);
TableRow row = new TableRow(this);
TextView tv1 = new TextView(this);
TextView tv2 = new TextView(this);
ImageView iv = new ImageView(this);
tv1.setText("Table row #"+Integer.toString(mRowCount));
tv1.setGravity(Gravity.LEFT);
//The following line causes my textview to
disappear
tv1.setLayoutParams(new
LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, Gravity.LEFT));
row.addView(tv1);
iv.setImageResource(R.drawable.divider);
//And the line after this one does the same to
my imageview
iv.setLayoutParams(new
FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT, Gravity.CENTER));
row.addView(iv);
tv2.setText("Add more text here.");
row.addView(tv2);
table.addView(row);
}
Unfortunately I've been unable to get this to work. The problem is
that whenever I assign the layout parameters to either my text view or
my image view, that view seems to not get added to my table row, or if
it does, its not at all visible. Does anybody out there have
experience formatting table row comments in code? I'd sure appreciate
being pointed in the right direction.
Thanks!

[android-developers] Compiling an app with JAR files or else ...
Hi, We have an application which runs as an Android Service in the background. Let's assume that we would like to have another application (an activity rather than a service this time) which is supposed to bind to this service (assuming that the service is already up and running when this application is started). The binding is provided through callback functions (as if the service provides an API for any application that wants to bind to it). When someone needs to compile an application of this sort, they either need to have the source code or the JAR files of the service. We would like to keep the source code to ourselves so I was wondering what the most convenient way is to distribute the code for the service for anyone to compile their applications that bind to it. JAR files are reversible as far as I know so that wouldn't do it. Is there any way to compile an app using an apk of another (the service application in this case) in Eclipse ? Let me know if there is a more suitable list to post this question if you think this is not the right one. Thanks in advance for your comments.

Re: [android-developers] CountDownTimer too slow ???
The calls to *onTick* are synchronized, maybe your code is taking more than
a second to execute. Log can be expensive, and with debug symbols enabled
your code will run a little bit slower than in real life.
Or maybe the end of times is close!! :P

[android-developers] starting service from launch icon
hi,
Im working on API 7 and I need to launch service without showing any
activity, my service will add status bar notification so user can
interact with application later.
I cant find any other solution then launching activity that will
finish immediately after starting service but this shows a blank,
white screen for a second so this is rather poor workaround.
I tried using broadcast receiver but this cannot be launched by
I got error ERROR/Launcher(105): Launcher does not have the permission
to launch Intent
{ act=android.intent.action.MAIN
cat=[android.intent.category.LAUNCHER] flg=0x1020
cmp=myapp.launcher/.SettingsActivity bnds=[83,238][157,317] }.
Make sure to create a MAIN intent-filter for the corresponding
activity or use the exported attribute for this activity.
I know there are apps out there which are doing that (or at least
looks like that) so there must be a way, thanks for help

Run the following code in the emulator and start a chronometer at the

// log some text each second :

{
private int i = 0;
@Override

Log.i("", "###" + i);

}
@Override
public void onFinish() {}
};
countDown.start();
Then wait a few minutes.
For example I stop when my chronometer was at 7min44s. The value in
the log was 448seconds => 7min28s.

Move the code out of a custom Application class and into a static data member. Do not refer to the class containing said static data members from your IntentService, and they will not be initialized. For example, you could simply make your custom Application class no longer extend Application, rig it up to follow a standard Java singleton pattern, and not refer to it from the IntentService (or anywhere else that does not need it). When one of your other components needs this stuff, they will refer to the class, causing it to be loaded and go through your 10ms initialization logic. > How can I do so > that the initialization check in my "Application.onCreate()" method be > not invoked in that special case, please?

[android-developers] Re: How to know what internal process runs an application
Thank you a lot Dianne and Rich for helping: I think that this discussion will be helpful to many other Android developers ;) I understand that I was not successful in explaining the core issue. Let me attempt to rephrase it in a more appropriate way. As far as I understand, when an application process starts, its "Application.onCreate()" method is invoked, right? Since I do not want to check that my application process is properly initialized in all my Activities, BroadcastReceivers, IntentServices, Services, ContentProviders..., I decided to initialize some variables during that "Application.onCreate()" method. Since the application process can be killed any time by the OS while it was running an Android Task, it may happen that when the end-user presses its launch icon, or access to it via the "latest task" feature (long-pressing the "home" button), the lastly stacked Activity on the Task stack may be the first application Activity to be recreated, and I would like to prevent from having to check the initialization in all "Activity.onCreate()" methods, for instance (even if it is just one line of code to invoke a static method, because, for me it's a bad design, since I may forget to insert that line of code in all Activities). You may say that I should derive from a common Activity which would check for the initialization: once again, I do not like this solution, because I have various natures of Activities, like a MapActivity, a ListActivity, a GroupActivity, a PreferenceActivity, and I'd prefer not introduce a basis class for each Activity nature. This discussion also applies to the BroadcastReceivers, IntentServices, Services, and ContentProviders: I do not want to check for the initialization nor derive from abstract class which would do the work. I prefer the concept of interception, and I prefer to have a centralized place where I know that all my applications components will go through, in order to check for the initialization. That is why I overload the "Application.onCreate()" method, because it meets all my requirements (except for the ContentProvider that may be invoked before the "Application.onCreate()" method has finished its execution), and that I know that this initialization checking and execution just takes less than 10 ms. However, one of my application component, an IntentService, needs to run in another process (this is a constraint that I cannot bypass): this is the exception to my rule, i.e., it does not need the initialization to be run, and moreover it should not. How can I do so that the initialization check in my "Application.onCreate()" method be not invoked in that special case, please? I hope that my question is now clearer. Thank you for reading, and hopefully for proposing a solution. Regards, Édouard -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Finding a project that people you know will get use out of will make it a lot easier to get some motivation. One popular idea I had was to make a fully functional app that works with your school's library.

[android-developers] Re: glReadPixels()
As it turns out I do have to be concerned with the y values in
glReadPixels. It was a major stumbling block. They do start at the
bottom of the screen. I used a combination of techniques to get the y
value I needed. I used 'getRawY()' from the MotionEvent and another
method of the view I was in called 'getLocationInWindow()' which
reports the location in the parent window of the current window. I
also used 'getHeight()' on the view also. My code looks something like
this:
int [] locationXY = new int[2];
button_view.getLocationInWindow(locationXY);
int mBot = button_view.getHeight();
int newYValue = ( mBot + locationXY[1] ) - event.getRawY;
The value 'newYValue' is fed to the glReadPixels routine. This works
for me because my layout is very simple. I also found the link below
helpful:

See what mLocalActivityManager.startActivity() returns. You have to
attach returned Window (or its root View) to your tab

[android-developers] Offering free and paid APKs on the Market
Hi, I'm thinking about offering a free / paid version of my app on the Market. I currently only have a paid application on the market (let's assume the current version on the market is called com.myapp). The idea would be to strip off some of the functionality in the free version. I'm thinking about the following approach : Starting from my current (and only) Eclipse project called com.myapp (using package com.myapp), I would : Move most of functionality into a new library project, using a new package com.myapp.common. This project would include most the current classes from my project. A lot of activities / broadcastreceivers / services would become abstract in the com.myapp.common project. Some redesign/refactoring would be in order so that the free/paid version can extend from these abstract classes to drive the logic correctly (free vs paid). Introduce a MyAppPro (using package com.myapp - to keep it aligned with the current version in the market) Introduce a MyAppLite (using package com.myapp.lite) I did a small POC and this approach seems to work to a certain degree. I can subclass where needed to provide additional functionality, and can also override certain layouts where needed. However, I was wondering if there were some good scenarios to cover the following : I use intents a lot to do both internal communication in my app, and exposing functionality to the outside world. If I have both a free and paid version of the app, how do I avoid that these 2 start to interfere. I have widgets in both the free and paid version. Free version widgets are a subset of the paid version. If a user has both the free and paid version installed, how do I avoid that the users sees duplicate widgets? I register a lot of broadcast-receivers. Again duplicates will come into the picture here. Do I need to ensure that in my free / paid version, the intent filters are properly "name-spaced" that they don't interfere with each other, to avoid that both the free and paid version starts picking up certain intents ? I register a lot of activities with an intent-filter (used for "share/send" functionality). How do I avoid mixing both the free / paid version. Is there a way to detect that a users has both the free app / paid app installed, and in that case, somehow deactivate the free version ? Are there any design patterns / out-of-the-box solutions for that ? Also, any pointers to existing resources would be great. Another approach that was thinking off was to just make the current version free, and use in-app-billing to turn it into a fully functional paid version. However, that would be difficult as I think there is no way to automatically convert my existing paid user-base. These would then all of a sudden get a free version with limited functionality when they update the app, and would have to go through the in-app-billing process (paying twice) to get the full functionality.

[android-developers] Re: starting Activity in tabbed UI from onTabChangedListener()
Please don't use Activities as tab panes. You are just setting
yourself up for all kinds of grief now and in the future. And since
this is deprecated, you will never see the many outstanding bugs
fixed.
If you must, refactor your code so that you can just use a View. I
know that can be painful, I've done it, but you are doing yourself a
favor, trust me.

[android-developers] Re: Curious NPE
Is onBackPressed called from a different thread perhaps? I wouldn't
have thought so, but stranger things have happened. And if that's
the case, how can I ensure that my variable is initialized. I cannot
construct it on the decleration as the object depends on the intent
passed in to the Activity.
My Activity can take a couple of seconds to display, and if I press
the back button quickly one of two things happen on my Nexus One: it
either doesn't register at all or that the activity flickers on and
off and I am back to the original Activity. In no case did it crash
in my testing.
But as I said, I got some other errors like this for a member that
should have been initialized in onResume.

[android-developers] starting Activity in tabbed UI from onTabChangedListener()
Hi
I got tabbed UI, where I use own tab layout by utilising
TabSpecs.setContent() to provide custom layout. As I wanted tab content to
be Activites not Views, I set onTabChangedListener() to do the job, with no
much success:
public class MainActivity extends TabActivity {
onCreate() {
mTabHost = (TabHost)findViewById(android.R.id.tabhost);
mLocalActivityManager = getLocalActivityManager();
mTabHost.setup(mLocalActivityManager);
}
}
and listener:
public void onTabChanged(String tag) {
intent = new Intent().setClass( context, NextActivity.class);
mLocalActivityManager.startActivity(tag, intent);
}
Listener's onTabChanged() is called, but nothing else happens, nor crashes,
nor logs. Hints?
PS: I also failed to follow reasoning why seting intent (so the content tabs
points to) equals setting view of tab itself (it all falls under
ContentStrategy in TabHost).
PPS: Fragments, I know, I know.

Sounds like it might be possible that onBackPressed can get called

If that is at all a possibility, maybe you should check for null in
onBackPressed! :-)

[android-developers] Listbox with ImageView and heapspace
I have a listbox which has an imageview in every item, the bitmaps for the images are loaded in the background as the user brings the items into view. The images are queued for loading in the background as the user scrolls through the list items. If I have a large list and I take my time scrolling through them, everything works great, however if I race through the list to the end, it will always crash at some point as it runs out of heap space. My guess is that so many bitmaps are in the queue and the resource allocated for each is not being re-cycled fast enough. I am not sure how I can improve this such that the resources are free'd as soon as they are no longer required. -- Regards, Sy -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
