[android-developers] Re: What is the best phone to buy for Android Development?
Doesn't really matter. I find myself testing on 4 different devices in the emulator - corresponding to different screen sizes. The only time I load into a real device is just before a release, and that's just habit (see what it looks like on real screen) rather than a requirement. The fact is that you have to test on multiple devices, and just because you own a real device as well doesn't help much. The only time I have ever used a real device for something meaningful is to measure frame-rates in games; the emulator on my PC runs at about 1/5th the rate of my HTC Desire 1 Ghz phone for 2D graphics so occassionally its good to see how fast the game runs on real devices. Most apps aren't real-time, and this is a pretty minor use. I would buy an Android phone/tablet if you need a phone or tablet for other reasons, and buy one for those other reasons. The fact is that a real device doesn't actually help you much in developing apps.

Re: [android-developers] General question about Android architechture
And I still submit my question: why Java? Or rather, why a virtual machine built on top of Linux, rather than Linux itself?? Several reasons: 1. Hardware portability. iOS runs on tightly defined hardware. Android is designed to be able to run on different CPUs and hardware architectures. The VM makes this possible 2. The VM implements a huge number of standard classes (effectively J2ME); trying to recreate these natively on top of Linux would be a nightmare for every developer. 3. There are a lot of Java libraries and Java programmers out there, and these are typically quite portable. 4. Real life Java programs are basically mostly calls to J2xx class libraries where the heavy lifting is done. The performance of the Java code itself is seldom an issue, as the real work is done in these native libraries. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Home, Menu, Back, Wallpaper, Play in different languages
My wallpaper contains instructions (in the app, web and Play) which look something like: 'To install the Wallpaper, from the home screen press Menu then Wallpaper then Live Wallpaper then ...' The problem is that in different languages these reserved words like home screen, Menu, Wallpaper and Live Wallpaper are going to need to be particular words in the translation, or else the translation will make as much sense as: To install the wall covering, from the apartment check press Food list then wall covering then Clearly for the instructions to make sense the correct reserved word in that language must be used. Does anybody know the official terms or where to find them in different languages for: Home screen, Home button, Menu button, Back button, Play (market), Wallpaper, Live Wallpaper, Settings, Application, and any other words that are effectively standardised in different languages for Android.

[android-developers] Re: Android Game Programming help
100% agree. Actually writing the nuts and bolts of a real time game on Android has very little to do with Android. You will need to know how to use the classes associated with I/O, like how to write an Bitmap to the display or handle touch events. This stuff is pretty simple, with plenty of on-line code snippets. The difficult/complex things like collision detection and implementing a physics engine all have to be written from the ground up, and will not contain anything specific to Android. What I found hard was getting the initial game framework setup. A real time game needs a couple of different threads, and when someone presses the HOME key the threads needed to be halted/suspended properly. It also needs to supply real-time environments for the real time game itself with the CPU rendering its little heart out, and environments like Help Screens where it can render once and wait for a user input. Writing this stuff properly requires a knowledge of the Android architecture and considerable experience in setting up game environments. What you want to do instead is take a game which already works, hollow it out, and insert your own game logic. The game demos in the SDK don't provide this; Lunar Lander (for example) will crash if you leave it at the wrong point and try to switch back to it. If these guys couldn't get it right, mere mortals have no chnace. This is why I also recommend Zechner's book. It builds two games from scratch - one using 2D graphics libraries, the other 3D - and they demonstrably work properly. And the programs are designed to allow easy substitution of some other game logic. He does a piss-poor job of explaining the Android architecture, but if you use his programs as a start point you don't need to know very much about it at all (a thoroughly good thing; its quite complicated). He does briefly discuss some specific game programming concepts like collision detection, but you will find more comprehensive resources on the web. What he does do very well is give you a fully working game with help screens, menus, persistent data and all the rest of it ready to modify to your needs, and this will save you a huge amount of work.

[android-developers] Re: Problem with R class, ids and layouts not resolved
Here is what I guess is going on:
If you cut-and-paste stuff from one Project to another in Eclipse, and
the stuff you copy includes a reference to the R class, you will
find that Eclipse will set up an import of the R class for the project
you copied from. This seems to be reasonable behaviour for most
classes, but not for the R class where each Project has its own.
This means your code can be looking at the wrong verion of R.
Go through the class(es) which fail, and remove any imports for R. You
will get errors wherever you use R. Hover the mouse over one of the
errors, one of the options will be to import the correct R class.
Select this, and the errors in the class will be fixed.

[android-developers] Re: Image Quality problems using Canvas and canvas.scale(Scale, Scale);
At the risk of stating the bleeding obvious, if you upscale a bitmap *anywhere* in your code by a factor which is not an exact integer (1, 2, 3, etc) then the system will not be able to exactly reproduce the original image, and will be interpolating and/or duplicating pixels to make it fit. Which gives you a not so great result. You have gone to great lengths to avoid scaling when you read it in (using Bitmap Factory Options), this is largely a waste of time if you scale it for writing using canvas.scale. You will still get scaling artefacts on write. You need to suppress scaling for read *and* write. The only way that I know of to get pinsharp graphics - with your bitmaps appearing exactly how you intended - is to write to a canvas which has the same resolution as the actual device (or View). The downside of this is that you have to manage all possible screen resolutions within your code, as you can no longer use the system to map a fixed co-ordinate space in your code to the specs of the actual screen. A pretty obvious trade-off between coding simplicity and image quality. If you are already relying on automatic output scaling for lots of other stuff in your code, you are probably stuck with it.

[android-developers] Handling system events: LunarLander vs Jetboy vs Snake
Both LunarLander and JetBoy in the SDK demos have the bug that they don't handle you pressing the home button in the app - when you restart the application, it says application stopped unexpectedly. These both run render/update in a separate thread, which appears to not be terminated. Snake handles home and back buttons quite well. It has a different structure, it is single threaded. I can simply change the thread.sleep() to be zero, and use it to implement my game engine in a single thread. But it actually draws the screen using a View.invalidate() call, which I have heard is slow, and my app is real time. So: 1. Is View.Invalidate() as used by Snake slower than the approach of locking the surface used by LunarLander and JetBoy, slower enough for me to care? 2. Can anybody suggest any game samples which correctly implement system events like the user hitting the home or back button? Many on the web are obviously derived from LunarLander or JetBoy and have the same problem.

The problem I have is that how does it know that my phone is the developer's phone? Because I am using the same credit card number as my developer account, or some co-incidence of email addresses? If so, this can be easily bypassed by using a different credit card number or email address for purchases, which many people would do anyway.

[android-developers] Getting actual device resolution
I have been using a simple 3rd party game engine, from the book
Beginning Android Games.
The example code uses a fixed resolution (320 x 480) and this is
scaled on output. Not surprisingly, the bitmaps and everything else is
scaled and looks pretty poor.
My code is set up to use the native resolution of the device and
handles scaling internally. I can modify the code to use whatever
resolution I want, and this works fine.
In this engine, the graphics and almost everything else is handled
through abstract classes and interfaces.
The way the game engine is set up, it doesn't actually use the Android
graphics engine until after the game environment is set up. The first
place that I can get hold of the actual resolution through SurfaceView
is in the run loop, way after the game engine has been initialised.
I need the screen resolution *before* I set up the location of sprites
and game state. Modifying the engine to move the game setup into the
run method would break lots of other things.
Can anybody tell me how I can get the actual hardware resolution of
the device (so I can set up the game objects properly) without waiting
until the run method which has access to SurfaceView?
dstRec in the following gives me the resolution, but this is way to
late for me to use when setting up the game.
public void run() {
Rect dstRect = new Rect();
long startTime = System.nanoTime();
while(running) {
if(!holder.getSurface().isValid())
continue;
float deltaTime = (System.nanoTime()-startTime) /
10.0f;
startTime = System.nanoTime();
game.getCurrentScreen().update(deltaTime);
game.getCurrentScreen().present(deltaTime);
Canvas canvas = holder.lockCanvas();
canvas.getClipBounds(dstRect);
canvas.drawBitmap(framebuffer, null, dstRect,
null);
holder.unlockCanvasAndPost(canvas);
}
}

[android-developers] Re: Handling asynchronous events and blocking
I can certainly create (say) a LinkedList of events which acts a queue of instructions for my main loop. My issue is that after processing an event, I have to remove it from the queue. According to http://download.oracle.com/javase/1.4.2/docs/api/java/util/LinkedList.html : Note that this implementation is not synchronized. If multiple threads access a list concurrently, and at least one of the threads modifies the list structurally, it must be synchronized externally. (A structural modification is any operation that adds or deletes one or more elements; merely setting the value of an element is not a structural modification.). This page then goes on to describe how to force an exception if two threads both try and update a LinkedList simultaneously. This doesn't solve the problem, it just tells you that it has happened. This must be a very common problem, and I would expect a simple standard solution. As I mentioned, on other platforms I have used a guaranteed atomic process (file creation)as a semaphore for synchronisation, but I doubt that is the recommended solution for Android ... On Oct 24, 4:28 pm, Studio LFP studio@gmail.com wrote: I figure you are running a thread that does all the processing as not to block the UI thread. If so, one of the ways I've been doing it is to add something like... public static LinkedListMotionEvent uiEvents; ... to a helper object and then check the length of it every time through the processing loop. You can either call length() on this or you can keep up with the count yourself which might be a bit faster. In whatever view you are catching touches, just insert the MotionEvent into this list. This should leave the UI thread clear and let the processing thread get the touches as time allows. Once I process the first event, I remove the event from the list and continue. I tend to only process one per frame so I don't cause hitching in the movement. If you are running about 30 fps, most people won't be able to touch faster than the ~33ms they have between frames anyways. I use a LinkedList so it keeps the touches in the order I insert them so I don't have to worry about out of order touches.

[android-developers] Re: Uploading same .apk to Market as two different apps
I want them to be the SAME app if possible, as this eliminates the need to worry about Preferences or anything else. (Only the paid version uses Preferences, so I don't have to worry about keeping the Preference selections made in the current free version). I can't simply make them absolutely identical, as the two versions currently are signed with different keys, and if I change one of the signing keys I won't be able to upload. Hence my idea to use the same source code for both, just signed with their existing (different) keys. I have no way of testing this stuff without trying it on the Market, with potentially catastrophic effect if I muck it up (having a 100,000 people getting an error message when they try to upgrade is not a good look). It seems a pretty simple thing that I want to do, convert my free version so it is the same as my paid version and hence only appears once on the user's phone and uses only one set of Preferences.

[android-developers] Re: Moving from free app to a paid model
I have just made a paid version of my free app. The only chnage I made to my free version was I included a market link to my paid version. My ratings dropped immediately. I used to get 65% of my ratings as 5 star, immediately dropped to less than 50%. This was nowhere made up for by 5 start ratings on my paid app. The psychology seemed to be that most users thought that my app deserved 5 stars, once I advertised a better version, they thought that it could no longer deserve the maximum 5 star rating if there was something better. My market position plunged, and the click-throughs dried up. I have just removed any mention of my paid app from my free app (ie the market link), and so my ratings are going back up. I just created a completely new package for my paid version, I don't think there is an easy way to avoid that.

So, you don't particularly like coding, but hope to sell apps on the market to supplement your income. Your background doesn't seem to include any OO langauges (including Java), there will be a fair learning curve. Can't see how this is going to work if you don't like coding, and don't have an idea of what you want to build, sounds incredibly boring. The nice thing about Android is that with 50 million users, it can be a niche application and still be commercially viable. What would have helped during your cancer treatments? An alarm/calendar system for chemotherapy? Did you have to take notes, or record food consumption, etc etc. With 50 million users, and only 1% have had cancer, that's half a million prospects. Sell to 10% of them and you have 50,000 users, and serious money. Build something you personally find useful or interesting, and you will get customers. Build a knock-off Notepad app and you probably won't.

In a test against a professionally-developed system, theirs failed to route circuits we had on our network, where mine routed them correctly (and they WERE working with the actual code, where again, I had the specs, but not the code, and implemented it in my own C code). It was part of my daily life at work, as I was the design engineer for the corporate backbone network (ALL of Amoco's most critical networks rode over my network).

[android-developers] Re: Help me to realize preferences scheme to use it between activities
I am a bit of a newb myself, but so far none of the responses seem super-helpful. You cannot currently use Shared Preferences to read the preferences in another package, the documentation says this is currently unsupported. If you combine the two apps into the one package, I think they can share Preferences. If separate apps, you should be able to load the Settings screen of app A from inside app B by sending an intent from app B to app A's settings screen. You may then also be able to do your login processing inside app A's setting screen, meaning that a login occurs within app A's settings before app B tries to access the server. As several people have pointed out, the correct way of passing information between apps is through a content provider, typically a database. However, Preferences are super easy to code up, and handle virtually all of the machinery. For a newb (such as myself and probably you), Preferences are more straightforward than Content Providers, and a solution based on Shared preferences is easier to implement if it can do what you want. That's my experience, anyway.

[android-developers] getSharedPreferences for a wallpaper
The standard Cube2 Live Wallpaper demo seems to handle Preferences strangely to me, in that it wires up an event handler which modifies a global variable. I don't want to to do that (or, more to the point, when I tried it didn't work for me). I don't see that I need to wire up any event handlers; can't I just read the preferences directly where I need them? It seems to me from the documentation/samples is that the *only* thing I have to do is add the lines: String PREF_FILE_NAME = cube2_settings; SharedPreferences preferences = getSharedPreferences(PREF_FILE_NAME, MODE_PRIVATE); String teststring = preferences.getString(cube2_shape, cube); anywhere in the animation loop, and teststring should be either a cube or a dodecahedron depending on the preference. It is always a cube. cube2_settings.xml is the standard one: ?xml version=1.0 encoding=utf-8? PreferenceScreen xmlns:android=http://schemas.android.com/apk/res/ android android:title=@string/cube2_settings android:key=cube2wallpaper_settings ListPreference android:key=cube2_shape android:title=@string/cube2_settings_title android:summary=@string/cube2_settings_summary android:entries=@array/cube2_shapenames android:entryValues=@array/cube2_shapeprefix / /PreferenceScreen If nothing else, the Cube demo doesn't show how to gain access to preferences from within its animation loop (that I can see), for the record can anybody tell me what I (and the cube demo) are missing to allow that? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Canvas frame rate very choppy in Live Wallpaper
I don't think OpenGL will help. I use canvas.translate and canvas.rotate extensively in my wallpaper, which runs very smoothly. AFAIK these commands just set mostly hardware flags for where to draw, and appear to execute instantaneously. You haven't posted any code, but I would make a bet on why it is running at 3fps. You are displaying images. I bet you do a jpeg rendering every time through your animation loop, and this is what is killing your performance. Draw the image to a bitmap, only once at the start (when a new image is first to be displayed). Persist it for the liefetime of the animation loop. Only do another jpeg rendering when you have a new image to display. In your animation loop: Translate the canvas Draw the bitmap Translate the canvas back If you have checked and you are *not* doing jpeg rendering in your animation loop then you should find out what line is causing your 300 mS delay (shouldn't be too hard!) and fix that.

[android-developers] Re: Canvas frame rate very choppy in Live Wallpaper
I think you are possibly doing this the wrong way. There is a canvas.translate() method which moves the canvas itself. This just sets the hardware to look at a translated location, so should be instantaneous plus or minus 1 nanosecond. The downside is that you will need to draw the image to a larger sized bitmap than the screen, to cater for the movement you allow in your canvas.translate call, 19 pixels all around in your example.

[android-developers] Help using custom Preference types - for pity or money
My new wallpaper is 99.9% finished. One thing I can't get to work, is using a third party color selector widget. This last 0.1% has taken over a week. I need help, and am prepared to pay for it if neccesary. It is that or go crazy. I have modified the standard cube demo to call an additional ColorPreference for testing. So all I am trying to do for testing is shoehorn a color selection preference into the standard cube demo. I have tried with two different color selector preferences downloaded from GitHub. My cube2settings.xml looks as follows: PreferenceScreen xmlns:android=http://schemas.android.com/apk/res/ android android:title=@string/cube2_settings android:key=cube2wallpaper_settings ListPreference android:key=cube2_shape android:title=@string/cube2_settings_title android:summary=@string/cube2_settings_summary android:entries=@array/cube2_shapenames android:entryValues=@array/cube2_shapeprefix / ListPreference android:key=mechanism_type android:title=@string/mechanism_title android:summary=@string/mechanism_summary android:entries=@array/mechanism_names android:entryValues=@array/mechanism_types / !-- com.example.android.livecubes.cube2.ColorPreference -- !-- android:key=favoriteColor -- !-- android:defaultValue=0xFFA4C639 -- !-- android:title=Your Favorite Color -- !-- android:summary=Blue. No yel- Agh! -- !-- / -- com.example.android.livecubes.cube2.ColorPickerPreference android:key=rotorcolour android:title=some title android:summary=@string/color1_summary android:defaultValue=#FF alphaSlider=false / /PreferenceScreen The first listpreference is from the cube demo; the second is a test one I put in. The third ColorPreference is commented out. It calls the first color picker I tried. If that is included, the system throws an error when I press settings. The fourth preference uses a different ColorPickerPreference class which I tried instead. This one allows the main preference screen to be shown, but I get a Thread [3 main] (Suspended (exception InflateException)) when I select this preference to modify. Without either of these preferences, it works as expected. Apart from copy and pasting the new color selector classes into my project and changing the package names, and the change to cube2settings.xml above, it is the standard cube demo, with the standard Manifest, cube2settings.java etc. This is almost the last thing I have to do to get this out the door. Its driving me crazy. I am missing something very simple. If somebody can suggest what this is, I would be extremely grateful. If not, I am making some obvious, simple mistake - I didn't write any of the code, I just tried to glue two simple demo programs together for testing. For somebody who knows Preferences, it is probably one minute to one hour to find and fix my mistake, and I am desperate enough to pay for this assistance. I can email you the cube test project and you fix my simple mistake. If you have a profile on this group, I am willing to pay some or all upfront. Please email privately.

[android-developers] Re: How to get the best double buffering?
In fact, the whole idea is to *not* create a new bitmap on each frame. Create the bitmap and clear it at the start of your animation, then just keep drawing to this bitmap. You keep it in scope, so the stuff you draw to the bitmap in previous frames is remembered. The only additional overhead from what you are doing now is writing out the bitmap when you have added all the new polygons for that frame. This is just a block copy, and appears fast. My animation loop works exactly this way, and whilst I haven't measured how long it takes to write the bitmap, I can assure my animation loop is very smooth.

[android-developers] Re: How to get the best double buffering?
From my own investigations, when you are given a Surface to write on, its contents are undefined but in practice the contents are the previous buffer used by Android's double buffering (for wallpapers at least it just flip-flops between buffers). Hence your flickering, as I think you correctly surmised. As Nightwolf said, you have to redraw every pixel. The easy way to do this is to create a bitmap the same size as the surface/canvas and draw persistent objects to the bitmap exactly as you are doing now, and then draw the bitmap to the canvas. This appears to be quite efficient, as its probably just a block copy. On Feb 17, 7:14 pm, MobileVisuals eyv...@astralvisuals.com wrote: I am painting polygons with the Paint class in an animation.

[android-developers] Re: Suggestions on best way to draw a laser in a 2d game
I bet you can make a pretty funky laser beam using the draw lines or fill polygon commands in the Canvas/Paint library. To draw basic unpulsed laser beam draw a transparent line of width 6 between a and b. Then draw on top an opaque line of width 2 between a and b. You will get an effect where the laser beam falls off in brighness from the centre to the edges. To pulse it, draw a short line segment of width (say) 8 on top of the unpulsed laser beam, and move its position between a and b every screen refresh so the pulse moves along the line. If you want your laser beam to be some shape other than a long thin rectangle, you can do the same thing with a polygon fill command and you can have the laser beam whatever shape and size you want.

Key parts of the problem. laser starts at 1 coordinate and terminates at another in 2d space and could be of arbitrary length (might be scaled if I decide to add zooming). Possible brute force solutions: 1) using rotation/transformation to manually draw a bitmap representing a segment of laser all along the required distance. (cycling the bitmap as required for animation) 2) Create a very large laser beam image (longer than I would need eg: 10px by 500px) and draw it at correct transformation. Looking at the BitmapShader and reading some of the SDK info about Paths, Paints etc it feels like there should be a better way to do this, but no examples I've found covers it. Any idea if there is a way to use a BitmapShader to paint using a canvas.drawLine or canvas.drawPath call to create this effect?

[android-developers] New market icons/developer console
I am confused about what the new graphics are for in the marketplace. Specifically, I have uploaded the 512 x 512 images, the 180 x 120 promo image etc. However, on my 2.2 phone, the market displays a graphic of the application at the top left. In my case this is a tiny, tiny version of my application icon, which looks terrible. My application icon is 72 px square, which is what the doco says it should be. I could make my application icon bigger, but how much bigger? And I don't want to just try various sizes, the only way I can do this is by re-signing my app as another version and uploading, every time I do this all of my users will be prompted to re-download. Hell of a way to test, by publishing every attempt to the market. Does anybody know the story? Specifically, what should I do to get a decent sized application icon displayed at the top of my download page on the market?

AppBrain Find your application at http://www.appbrain.com/ Claim it as the developer. If you have enough users of your application (about 15,000 I think), you will get access to very detailed stats on your users - breakdowns by age, phone type, country and gender. The more users you have the more detailed the breakdown. The day that my application reached the minimum and I could see my app stats completely changed my understanding of who had downloaded it. I thought my app would appeal to younger users and be more attractive to men. I also thought I was doing well in Germany and Korea based on the languages of the comments. All wrong. My peak demographic is 35 year old women. I don't have enough users yet to see the percentage of my users in Germany or Korea, but apparently 5% of my downloads are in Italy despite never having received a comment in Italian. There is one potential source of error - the population that is measured against is not the general android population, but the AppBrain user population. I don't know how representative this is, but its certainly way better than what the Market gives you (ie better than nothing). Its a really great free service. It also skates to the very edge of what can be done without compromising user privacy, and in some aspects I believe it crosses the line. Not your problem though; enjoy the data they give you.

[android-developers] Sending custom intents from application to service
I have a wallpaper app on the market. I have almost finished a
customisation application for it, which I want to sell. Because it is
a wallpaper, I can't use a launch intent.
I have now spent many days trying to simply pass a custom intent using
BroadcastReceiver. I can't find a single example on the net of doing
this between two different applications. In desperation I post my best
guess as to what should work, although I have tried many permutations.
Stepping through with the debugger and I find the sendBroadcast is
executed but nothing is ever received.
Any help on where I am wrong, or to some code that I can use as an
example, may stop me going crazy:
My sender has the following on a button click:
Intent intent = new Intent();
intent.setClassName(pack.name,
pack.name.rtestactivity);
sendBroadcast(intent);
My receiver has the following manifest:
?xml version=1.0 encoding=utf-8?
manifest xmlns:android=http://schemas.android.com/apk/res/android;
package=pack.name
android:versionCode=1
android:versionName=1.0
application android:icon=@drawable/icon android:label=@string/
app_name
activity android:name=.rtestactivity
android:label=@string/app_name
intent-filter
action android:name=android.intent.action.MAIN /
category
android:name=android.intent.category.LAUNCHER /
/intent-filter
/activity
receiver android:name=rtestactivity$AlarmReceiver/receiver
/application
/manifest
and the following Java:
package pack.name;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class rtestactivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// set up a button to show mysemaphore value
final Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
Toast.makeText(rtestactivity.this, mysemaphore,
Toast.LENGTH_SHORT).show();
}
});
}
public static String mysemaphore =not received;
public static class AlarmReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent){
{
mysemaphore = Received;
}
}
}
}
Always the same. Whatever I do, the receiver is not called - the
debugger steps through the sendintent, but nothing seems to happen.
I write in desperation.
Thankyou for any help you can provide.

[android-developers] Market expanding to technically non-compliant devices?
Looking at the Developer's console, I note (correctly) that my application needs permissions for touch-screen operation. I don't think it used to do that, but maybe I just didn't notice. Furthermore, touchscreen is a standard part of the google android hardware specification, and it is hard to see how it could be a security issue. Perhaps the market is being expanded to allow devices without touchscreen (and hence not android hardware compatible) to applications that they can run, in much the same manner as the market will filter out apps that need high res if you are on a low res phone ? Why else might they filter on touchscreen? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Explicit intents
I have worked my way through the Notepad example and sort-of understand how the intents are passed back and forth. Basically, in Notepad the intents are read (mostly) in onPrepareOptionsMenu(). The system is polling the intent status within the code. That strikes me as a somewhat arbitrary decision; menu items are not directly connected to intents, and intents themselves are asynchronous activities. Other apps appear to work similarly. What I was expecting was a method called something like onReceivedNewIntent() which I could override, and centralise my intent handling logic. That would mean that intents were using the same pattern as UI events, and explicit polling logic is unneccesary. Is this it? Do I have to include my intent checking logic into some other handler that I know will be called, like onPrepareOptionsMenu, or is there some way of explicitly wiring an event handler to a received intent? Sorry about the noob question; I still don't get it, and feel like I am missing something important. . -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Explicit intents
Thankyou for your reply. Thankyou also for answering the last question I posted to this forum, and thankyou for writing the best book I have on on Android programming. I have an app in the Market which is going very well indeed, but I am having lots of trouble taking it to the next level. Lets say I have an Activity on top of the stack. It passes an intent to another of my apps but doesn't finalise, and the new app is now on top of the stack. It sends an intent back to the original application. This must cause some method to be be run in the original application. I was expecting an explicit handler to be invoked; this is how the system notifies apps that UI events have occurred, which seems the same sort of thing. An onIntentReceived method, like an onButtonClick method. I note that there is an onNewIntent method, but it has limitted applicability, and doesn't seem that commonly used. If the original app was not finalised, OnCreate will not be run again, so I can't depend on that. I note there is an onResume method, I assume this is always run when an existing app is moved to the top of the stack. So I could put getIntent() statements in both OnCreate and OnResume methods. This seems wrong, and isn't how the demos generally work. An intent is passed to a Class, and not to a method. What method is actually run when a new intent is received? Where can I reliably put my getIntent() logic to work out what my app really has to do? In onResume and OnCreate, or in onRestart or in onNewIntent? Or in some other manner? I want to centralise my intent handling logic, but don't know the simplest/most reliable method to put it in. Can you make any suggestions? Do these questions at least make sense to you? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Extending SimpleCursorAdapter
I'm an Android newbie, stuck on a problem for a over week now, if I knew what I was doing it would be 10 minutes work. Im using the NotePad example as a base for an application. This binds a ListActivity to a Provider. Its perfect, except it uses SimpleCursorAdaptor, which means the list only binds to and displays one item per row. I want it to display two items, both bound the Provider. Or more accurately display the text from one Content Provider field and an icon which depends on the value of a different field. This sounds like a pretty simple thing to do, a very slight modification to the NotePad application. Trouble is, I have no idea on *how* to do it. I really need a starting point, and approach to use. So far I have tried (unsuccessfully): * Hand populating the ListView by reading in the Provider data and populating an array in OnCreate. This works, except as the data is not bound the List does not update when I add an item. * Extending SimpleCursorAdapter with a custom getViewBinder. Could still only bind to a single column. * Building my own ListAdaptor. Couldn't get this to work. * Concatenating both fileds together and parsing 2 fields into 1 field read/write. The next thing I will try is extremely tacky running two separate simpleCursorAdaptors in two views in a Linear Layout, fudged so the row height is identical, and duplicate the logic. I say this only to show that I really, really have tried. Could someone give me at least a hint as to how I can create a custom CursorAdaptor which binds to two fields instead of just one like SimpleCursorAdapter?

He spends a great deal of time explaining how difficult that is. This flies in the face of modern software design, which says build it right then build it fast. He basically says throw away most of the benefits of using auto-GC languages such as Java by writing your code in a very artifical way which avoids allocating memory. It is a pity because he could have told us some things we (or at least I) don't know, such as how the GC is triggered, whether it is device dependent, whather there are calls to suspend repacking the heap, practical stuff about how to best use a GC language for real-time apps.

[android-developers] Re: If I turn off Copy Protection, what will happen?
I have just gone through exactly this, except my app is free. 1. I know a (pathetic) 6 people with Android phones. One couldn't see my app. We compared which apps he could see; he was missing about 10% including mine. 2. The user who couldn't see the app owns a Samsung Galaxy. There is a known issue that it will not accept copy protected free apps. 3. I removed copy protection from my app and updated the Release number. Everything worked exactly the same in the market, no problems. 4. My friend could still not see the app. But by the next day, downloads had increased ten fold. I did make a couple of other minor changes, and at that stage it had only been on the market for a week. I can't see how this is related to removing the copy protection, because both before and after I removed the copy protection 5 out the 6 users I know could download, most unlikely that suddenly 10 times as many people could download when it made no difference to thje 6 people I know. Neverthelessthe sudden jump did occur at exactly the same time, and has remained at that level. Whatever it was, I'm not complaining. 5. My friend still can't see it on his @#$%^ Samsung Galaxy.

[android-developers] Re: Piracy Breakdown by Country
I am also an Australian software developer. I can state with absolute certainty that these figures are absolute bullshit. 92% of apps running in Australia are not pirated. It is absolutely ridiculous. Anecdotally, as a developer I have sought our everybody I know with an Android phone, maybe half a dozen techies and half a dozen normal people. None of them are even aware of a pirate market in paid Android apps. The chances of 12 people in a row being in that 8% - impossible. More generally, my app is a live wallpaper. Here is an interesting stat. My uninstall rate dropped by 20% when I included instructions for how to run a live wallpaper. At least 20% of android market users appear unfamiliar with how to run a Live Wallpaper. Yet the statistics presented imply that 92% of Australians not only know how to install pirate apps, but also do so. Sound plausible to you? Australians are no more likely to pirate software than people in any other developed country. 92% of Australian android phone users obviously don't pirate android software. For that matter, 54% of Austrians don't pirate software either, but whatever fraction it is (I'm guessing a couple of percent at most), Australians and Austrians aren't going to be that different. The figures are clearly and obviously wrong. The most basic common sense should tell you that. On Aug 28, 3:58 pm, gosh steve...@unimelb.edu.au wrote: Hi Dave, Thanks for the stats - as disconcerting as they are. As an Australian software developer I was very disappointed to see Australia up top in the percentages on your scale of software pirates, wrt to your app - which I find hard to explain, subjectively or otherwise. I'll make a few points though (I'm assuming your figures are for your utility 'Screebl Pro', via your link): * Having some background in data analysis, I don't consider sample sizes under 300 to be statistically significant - which leaves you with 4 rows of data at this stage. * Going on your app, the US is the only place where Android is a big success thus far - I do know that 'utility' programs are a bit 'techie' for most regular phone users, but I'm thinking percentages here. * Android phones are fairly few on the ground in Australia (in my limited experience with other Android owners - other owners have been either software developers/publishers or university students, many of whom are from overseas - many/most countries). That said, since the 'main' telco here (Telstra) began selling Android phones here in April 2010, some regular folk/mums-and-dads are now starting to buy them…. i.e. The fact that australia is 4th in your list of overall downloads is very surprising to me, given the great lack of Google/Android-phone focus upon Australia - I thought it would be down around the NZ figures. Note: Most ads I've seen for Android phones here do 'not' even mention 'Android' at all (E.g. the recent ads for the Samsung i9000 Galaxy S ) - so I assume its either a perceived marketing negative, or its not worth the 'copy' space the single word would take up. * As a former president of the Australian Software Publishers Association, I know that Australians generally 'do' buy their software when its not open source - which is the main precursor to a country having a software industry. Its a part of the 'a fair go mate' ethos here - so Indy developers are likely to do well here - and do, given an avenue to market. * I do know that there are lots of software developers in Australia 'very pissed-off' with Google in that we are unable to 'sell' our programs in the Android Market (even though our customers can buy them from elsewhere) - e.g. I've had programs sitting here collecting dust for 12 months (yes, 365 days, one planetary orbit around the Sun [the one thats 93 million miles away] - no actions, and worse, no words about actions, from Google) come Tuesday this week see:http://www.digitalfriend.org/blog/month2009-09.html- but that is unlikely to cause a software developer to pirate other software developers hard work. I certain haven't and wouldn't. That kama is reserved for Google (and then Android), not for fellow software developers. i.e. If you are unable to circulate your own work, ones enthusiasm eventually dries up and withers on the vine, such that, in my case at least, I've abandoned my daily usage of the Android phone itself, and now use an alternative smart phone from a company with a global perspective instead. * Its true that, within the list of countries wrt your downloads, Canadian, Kiwi and Swiss developers also cannot sell their apps on Google Android Market to their own customers - so if it was 'a disgruntled developer issue' re Australia, you would likely see it there too - but as I've pointed out, your figures for those countries are statistically insignificant, so that doesn't constitute evidence either way. * I'm not surprised at your figures for Japan - even major
[android-developers] Re: New to Android and programming
I would go further than that. If the OP has no programming experience, then Java/Android is an almost impossible starting point: 1. The online doco is hopeless. Yes, as you say they all assume a pretty high level knowledge of Java to start with. Worse, for the beginner, is that unlike some other IDEs/environments I won't mention, the class library doco doesn't provide full functioning programs or even code snippets illustrating use. And these are hard and sometimes impossible to find. 2. Teach yourself OO programming? Are you kidding? Teaching yourself Fortran, C, Pascal etc is hard enough, and Java/C#/C++ are that squared. It would be easier to learn C, then jump from there into Java. And Android isn't just Java, its XML as well. Learn all that when you have never written a program in your life? 3. The environment is that much harder and slower to use because of the indirectness of cross-compling and running an emulator. When people first start coding, they are testing changes on a line-by-line basis, and the whole emulator thing is even more of a PITA. I love this stuff, don't get me wrong, and a lot of it is complicated and difficult because it has to be, but I can't think of a more difficult environment to learn programming for the first time than Java/Eclipse/Android.

Are you good at learning quickly on your own? If no to either, probably a good idea to take some time to learn Java on it's own. It has some quirks you need to learn. Android has quirks you need to learn. Depending on your background, learning both those quirks, at the same time, will be an exercise in frustration.

[android-developers] Re: Error in an XML file eclipse
I have exactly the same problem. Whever I open string.xml and some other xml files I also get a Java Null Pointer error. Typing even a single character triggers it. I can look at them fine as xml, but Resources view is broken - the left hand pane has the thin lines that should connect the elements in the tree structure, but no elements listed. Saving the file also creates null pointer errors. You can use editors that don't have a graphical view in the left hand window - for example the xml editor works fine. Unfortunately the more useful editors all show heirarchies and don't work. It is true even for the default files created by new - android project. As I say, the xml itself looks fine; its related to how the information is shown in the left hand window; if it uses a tree representation of the data, it throws a Null Pointer exception.. Whatever it is, its a PITA. I would completely remove and re-install the whole devel environment if I was sure it would fix it.

Correct. You may also need to manually change app Title in your
developer console
Tried it.
The app name is set in the developer console; doesn't matter what you
use in the app.
Unfortunately, to change anything in the market youhave to re-load
your app, and it checks that the version number is higher before it
will accept the new apk. So you can't rename without also incrementing
the release number.

[android-developers] Finding out the screensize and using my own canvases
I've never programmed in Java before, or used the Android SDK until a couple of weeks ago. I am rewriting a C# .Net graphics application, spooky how similar the environmets are. Anyway, my app draws lines and shapes in layers on different bitmaps, and combines them to do 2D animation. I handle all the scaling in the app. I used the LunaLander demo and just inserted my code, works brilliantly on the emulator at 600 x 400 res or whatever it is. I have tried using it on higher res emulator screens (which is what I am writing it for) but the Canvas provided by the doDraw is smaller and so I only see a window of my generated screen, when I draw my Bitmaps to the canvas in the doDraw() they get clipped. I can't see where I change LunarLander (or any of the others) to allow it to just use the device's native resolution. All my code uses the canvas dimensions I get in the canvas in the doDraw. What I thought would be easy is to just get be given the canvas in the doDraw which gives me the whole screen at its native resolution and then my app handles it all. I can't see how or where to do this. I know this is a bit of an ask, but is there some simple quick and dirty change that I can make to Lunar Lander or the others which gives me a full screen canvas at native device resolution to handle in my doDraw?
