you can use most normal Java File operations. If you want to access the sd card you will need to set the necessary permissions.

[android-developers] Re: Creating step-by-step tutorial in app
What I do in one of my apps (see middle screenshot) https://market.android.com/details?id=de.stephanwiesner.fotocommunity is that I display a popup that contains a custom dialog displaying an image. Sitze set to just fit the picture. In my case it can be zoomed and panned, but it could easily include swipe detection and not be movable. Just thinking about it, I believe that is exactly what I will do to include a first-start-tour-of-the-app .-) What you can also see in the screenshot is that there are two menu bars. The user can show/hide them with a tap. In your case this could be a navigation bar to make sure that the user can skip the tutorial or whatever you want him to be able...

[android-developers] Re: Android fragmentation study
I agree and actually profit from it. As a private developer I hate that I have to write Bugfixes for single devices/Android versions (just thinking of the Galaxy SI lagfix thing gets me goosebumbs) but in my professional life I am a software tester and we actually earn our money by offering our clients to have us test their apps on different devices/Android versions. As Dianne mentioned there are actually not _that_ many differences/ bugs, but they are real and they can get very expensive (again think lagfix). Greetings from Zurich, Stephan Wiesner On 11 Jan., 23:31, Christopher Van Kirk christopher.vank...@gmail.com wrote: Yeah, I would respectfully disagree with your assessment. Making software is a business. An investment. To reap maximum rewards on that investment the product has to have as much reach as possible, meaning the OP is absolutely on point about OS upgrades. Who is going to spend 10k, 100k, 1m, etc, developing an app whose target market is less than 1% of active installs? 4.0 won't be an attractive target for developers until it commands at least 80% of the installed market, which will likely take at least a year to occur, perhaps longer. Comparing handset differences with browser difference is just absurd. How many browser versions are there? Five maybe six? An average Android app has to deal with over 600 different devices today. That's a difference of 100x. This number is also growing at an exponential rate, so even if you can manage to test on all of those devices, in three months you'll probably have to do the same number again. What you're apparently not appreciating is that unlike the PC/Mac world, the Android world lacks strong compatibility standards and more importantly, conformance testing. As a consequence, devices tend to have niggling and chronic differences that in aggregate make for an inconsistent and unstable feel for the platform. You really have to have a very large operation or have a very unambitious app to make an app with long reach in the Android world. By contrast, the Apple approach is that one size fits all. From a small or independent developers perspective this really is preferable, because you know if you test it and it works on one device it's going to work on all of them, and there are millions of them out there. You simply don't have that guarantee in Android. It's no accident that the most profitable app market is to be found on Apple devices. Don't get me wrong. I'm not an Apple fan. But having spent considerable time fighting with device peculiarities in the Android ecosystem instead of adding features to my app, I find that I long for the simplicity that the Apple ecosystem guarantees. On 10/28/2011 12:01 AM, Studio LFP wrote: Eh, it's not that bad. If you look at the history of developers, we're already use to having to deal with a lot worse fragmentation issues than Android. Anyone that's ever developed a website correctly knows that supporting the available web browsers is a lot more of a challenge than with Android versions. Windows, Mac OSX, a ton of server technologies, databases, etc., they all have tons of different versions available to support. Most companies stick with older versions because it is what they have and it is working. When it comes to Android, I've been pleasantly surprised at the efforts Google has gone through to help manufacturers upgrade. Even though 2.1, 2.2 and 2.3 are different, they aren't so much different that in most cases you can't treat them as 2.x. It seems to me that Android is more broken up in 1.x, 2.x, 3.x and now 4.x instead of the individual versions themselves. I'd rather a little fragmentation in Android than for them to pull an Apple and everyone is the exact same, right down to the hardware level.

[android-developers] GPS does not stop after ending my app
Hi,
I have an app that uses MapView to display data. It uses locationManager to
determine the position of the user and if use of GPS is allowed by the user,
GPS is used.
The problem is that the app does not stop using the GPS (and draining
battery).
I start it using:
locationManager = (LocationManager)
getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
1000 * 60, 20,
new GeoUpdateHandler());
I tried this in onPause() and/or onDestroy(), but it does not help, though
the methods are
@Override
protected void onPause() {
super.onPause();
locationManager.removeUpdates(this);
log(pause);
}
@Override
protected void onStart() {
super.onStart();
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
1000 * 60, 20,
this);
log(onstart);
}
Any ideas?
Thanks,
Stephan

Hi TreKing,
thanks for your answer. I removed the new GeoUpdateHandler, but that

My Activity extends LocationListener:
public class ShowMap extends MapActivity implements LocationListener
so if I provide this on both methods it should work, should it not?
@Override
protected void onStart() {
super.onStart();
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,

[android-developers] (JSON) Download fails in 2.1 but works in 2.2
Hi,
I use JSON as an interface and my code works fine on 2.2 devices but fails
on motorola 2.1 devices
The reason is that not the whole JSON file is downloaded, but only some
(always the same) part and than it stops.
URL url = new URL(http://www.somelink;);
picCounter = 0;
URLConnection ucon = url.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
// breaks in 2.1 but works in 2.2
String text = new String(baf.toByteArray());
Is there an IO issue in 2.1?
Thanks,
Stephan

[android-developers] How to cache Websites
Hi,
I develop an app that is very content centered. Content consists mostly of
html pages (its basically an app version of an existing homepage with some
added features like GPS and camera), so most of the app will just run inside
a webview.
The app is intended to be used mostly offline, though, so I need good
caching mechanisms.
Any ideas how to handle the caching? Basically I would need to check wether
a html page and all pictures are already on the device and only load them
otherwise.
Do I need to parse the html for the links to the pictures or are there
better ways to handle this?
HTML 5 caching seems to work, but I don't feel that I am in control. For
instance: The webview does react to my .manifest file - but caches pages
that are not contained there too.
Using this code, my pages are cached:
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebChromeClient(new WebChromeClient() {
@Override
public void onReachedMaxAppCacheSize(long spaceNeeded, long totalUsedQuota,
WebStorage.QuotaUpdater quotaUpdater) {
quotaUpdater.updateQuota(spaceNeeded * 2);
}
});
webView.getSettings().setDomStorageEnabled(true);
// Set cache size to 8 mb by default. should be more than enough
webView.getSettings().setAppCacheMaxSize(1024 * 1024 * 8);
Thanks,
Stephan

[android-developers] Blackbox testing android apps
Hi, anybody using testing tools for end2end/regression testing? As apps are often developed by outside contractors we do not have (full) control over the source code and need to be able to do blackbox testing.

But even HP does not yet support that. I am currently playing with http://code.google.com/p/robotium/ which is a good starting point.

:-) No, there is no camera involved. They stream the userinterface to your pc and back. Looks exactly like the real thing. It is somewhat slow over the internet, but fast enough in an intranet. If you buy/rent an iphone, you get a real iphone and can send it any interaction (sms, touch, movement, etc.) you want and see what happens (like I said, no emulator). They have quite a range of devices, including different carriers. This is great for someone like me, who has to fight with bugs that only apear on certain phones (google maps on motorola defy in my case). That way I can install a build on that phone, see if it runs and evaluate any errors.

[android-developers] Re: Pretty sure Google Analytics for Android not working
As an add on, here is my code. I have set up TWO GA configurations, so
that I can differ what my beta testers are doing and what my real
users do. I needed that as well to be able to figure out how GA works.
As you can see, I use automatic dispatching.
Custom variables are used as well, but I have yet to find them in the
GA interface. I personally find misusing event tracking a great way
to see results like 41% of my users use Galaxy S phones (HTC is
growing faster, though, the Desire HD seems to be the current phone of
the day).
This information led my to do a lot of performance tuning, as the
Galaxy is so slow on disk/db operations.
private void initTracker() {
tracker = GoogleAnalyticsTracker.getInstance();
if (isReleaseVersion) {
tracker.start(UA-xxx, 60, this);
tracker.trackEvent(Gipfel, Version, VERSION, 1);
tracker.trackEvent(Device,
android.os.Build.BRAND.toLowerCase(),
android.os.Build.MODEL.toLowerCase(),
1);
tracker.trackEvent(Model,
android.os.Build.MODEL.toLowerCase(),
android.os.Build.FINGERPRINT, 1);
tracker.trackEvent(Android,
android.os.Build.VERSION.RELEASE.toLowerCase(),

Are you calling .dispatch() occasionally? Queued up pageviews and

don't get sent to the server until (1) there's network, and (2) you
call
.dispatch() on the tracker object.

[android-developers] Re: Performance issue with mapview when using large number of items
Thanks. My current solution is still that I only display markers in a certain radius of the center. That works fine, as the markers are peaks/cabins in the swiss alps and the user knows where the peaks are anyway. If I want to expand my app, though, I need a solution that scales. By now I have found several Javasript APIs, that handle this problem in a way similiar to what you suggested: by clustering markers. e.g.: http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/1.0/ I haven't found the time to solve that yet, as it is not pressing at the moment. But I will probably define areas (e.g. Berner Oberland, Wallis, Tessin) and countries and cluster the markers located there.

clicked on the screen.
I found something like overriding the onTap(GeoPoint p, MapView)-
Method of an Overlay, but I do not understand how to draw then this
points into a MapView. Do i have to call the draw()-method for each
new point?
Of course the GeoPoint has to be transformed into pixel-format with
the getProjection().toPixels(GeoPoint gp,Point px)-method.
Can somebody give me a good template?

[android-developers] Re: Performance issue with mapview when using large number of items
Thanks for your reply. I have thought about that, but can't find a good solution for that either. Sure, nobody needs them all at zoomed out level. But the user needs to see that there are at least some at a location (like I said, whole country). So I would have to, don't know, show only one in ten or something like that. They are clustered in the mountains and far between in other areas. Meaning I would have to calculate, what? The distance between all points? How would I decide which to display and which not to display? The problem gets even more complicated, as there are even some points in other countries all over the world (very few but increasing with use), so the users DO zoom in and out a lot. Thats why they need to see in which countries/areas there are some points. Hmh... But you are right, if I want to grow my app there has to be a way to decide which points to display if there is a performance penalty for each point.

How would I decide which to display and which not to display? As MrChaz alluded to, you'll want to cluster your points at zoomed out levels. One dumb implementation could, for each zoom level, define a Cluster which is a collection of markers. You'll have a set of Clusters and a pivot point in each cluster to compare to. For each of your markers, iterate over you set of clusters. For each cluster compare the market against the pivot . If it's close enough (in screen terms) you add it to that pivot's cluster, otherwise it starts it's own cluster and becomes the pivot of that cluster. Once you're done you'll have a set of clusters for each zoom level and that's all you'll have to display, either based on the pivot or the average location of all markers in the cluster. You can cache this data structure so you don't have to rebuild it each time and perhaps only load the cluster set for a given zoom level when the user zooms to that level. I just pulled that out of my ass so no idea how practical it actually is, but should give you some idea on how to proceed =). --- -- TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.

On 14 Jan., 00:45, Bob Kerns r...@acm.org wrote:
A couple things MrChaz and TreKing didn't touch on.
First, I'd make certain you're not doing something to cause the draw
method to be called 7000 times!
Second, I'd make sure you're not doing something horribly expensive in
there -- perhaps something allocating a lot of memory and triggering
the GC. That's probably not your issue, but capturing some timings on
the drawing calls is probably worth your while anyway.
Third, and probably most important -- rather than drawing 7000 items
on each draw call -- draw the 7000 items into a bitmap, and draw that
bitmap, translated and scaled appropriately. When you get off the edge
of the bitmap, redo it for the new position and/or scale. Make it big
enough to allow for smooth scrolling in the immediate vicinity.
You can draw your 7000 items with a degree of transparency, so they
overlap and add up density. That's not the ideal way to show
clustering, but it's a start. A more sophisticated approach would be
to draw into a grayscale bitmap with a density distribution image, and
use the resulting density bitmap to index a color map.
Or if you prefer iconified clustering, rather than visual illustration
of the clustering: wherever the density is over a threshold, find the
centroid of that area, integrate the total score for that area, and
draw an icon of that diameter.

Hi, I try to display HTML formatted text in a TextView contained in a ListView and can't get any formatting displayed. Linebreaks are displayed correctly, so the HTML formating is executed (at least to some extend). I download the text from the web and it contains br-tags (which are displayed correctly) and simple tags like b and i. I also tried things like small, etc, which I found on different Android tutorials. Any way to get some formatting (sizes, colors, anything) into my TextView? ListString titles = new ArrayListString(messages.size()); *Spanned text = Html.fromHtml(text);* titles.add(text.toString()); ArrayAdapterString adapter = new ArrayAdapterString(this, R.layout.row, titles); ListView list = (ListView) findViewById(R.id.list); list.setAdapter(adapter); My TextView: TextView xmlns:android=http://schemas.android.com/apk/res/android; android:id=@+id/TextView01 android:layout_width=wrap_content android:layout_height=wrap_content android:textSize=@dimen/text_size android:text=temp / Thanks, Stephan -- You received this message because you are subscribed to the Google Groups Android Developers group.

A, thanks a lot. That was a quick fix :-) Happy greetings from Lucerne, Stephan On 23 Dez., 17:48, Kostya Vasilyev kmans...@gmail.com wrote: 23.12.2010 19:10, Stephan Wiesner ?: *Spanned text = Html.fromHtml(text);* titles.add(text.toString()); Take out the second line (toString), and carry the result of Html.fromHtml as a CharSequence (or Spanned) all the way to TextView.setText. What this code does is first parses the HTML and creates markup (behind the Spanned object), and then throws the markup away in a conversion toString(). -- Kostya Vasilyev -- WiFi Manager + pretty widget --http://kmansoft.wordpress.com -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: where is my data?
thanks for the fast reply. only thing is: getFilesDir() returns /data/data/de.stephanwiesner and, like i wrote, that dir does not exist (or is not accessible) Furthermore I read in Sams Teach Yourself Android that the data should be in /data/data/package name And, I am sure that it was there last week. I have copied my database file several times to my PC for further processing and can't do that anymore, as I don't find it :-() My phone was never rooted.

Re: [android-developers] Re: where is my data?
Yes, I can read my data. Frankly I just wanted to copy my database via eclipse ddms to my PC for analysis. Guess I will have to mail it or something .-) Thanks, Stephan 2010/12/21 YuviDroid yuvidr...@gmail.com: Still, you can access that directory through your app. Try writing and reading a file there and it should work fine.

What you are experiencing is the normal state of affairs for Android development -- you can access your app's local files on an emulator, or possibly on rooted phones (not sure about that), but not on regular hardware. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to *Advanced* Android Development_ Version 1.9 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: where is my data?
ähm, actually, i do not have an (external) SD Card. The phone has 8 GB on its own, so no need for a card. Its actually very interesting to see how many apps don't work without a card .-) Writing to the internal card would be great, though. Did not think of that and I will try that right away. I just wrote a PHP script I can send my data to and that forwards it to, ähm, it works, but might be a little overkill... Stephan 2010/12/21 Sarwar Erfan erfanonl...@gmail.com: If you can read it from app, why dont you just copy it to sdcard by writing some lines of codes in your app? Then you can get it to your pc from sdcard. Regards Sarwar Erfan -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How to deploy and display images in App
Hi, i have a little app that just displays a number of pictures and texts (think quizz). I can load the text and filenames from an XML file and display them as text. And I can display pictures from a webpage (using ImageSwitcher) if I provide the full URL as a filename. This requires an internetconnection, though and my app is supposed to work offline. What I don't manage to do is: - load pictures that are stored locally as part of my app (e.g. in the drawable folder) - where in my app would i ideally put those files? please help me out with a code example.
