Re: [android-developers] How to gracefully terminate a remote service process?
This is a problem that the Google engineers have acknowledged. As you probably know, the issue is that the Android OS does delayed garbage collection of - and possibly reuses - dead porcesses, however the process name remains that of the last app it hosted, as reported via DDMS or via phone's running processes. Forcefully killing the process may seem to placate your users, but as you know is frowned upon by the Android engineers.

Re: [android-developers] Re: how to create irregular polygon and handle events within its boundary
I suppose it seemed simple for me since I'm done it with AWT before. Basically, you build up a Polygon object with vertices. You pass it to the Graphics.draw method to display it (or not if you want an invisible hit test layer over the image). You intercept click or touch events and use the Polygon's inside() or contains() method to do the hit test. Depending on the complexity and display size of the image, you may run into some hit test accuracy issues due to the touch UI. If you have the original artwork in Adobe Illustrator, you ought to be able to get a vertex list therefrom.

Re: [android-developers] Re: how to create irregular polygon and handle events within its boundary
Vectoring parts of a photographic image is going to be more difficult than the example I lnked. I think you'l have to zoom the vertices in the polygon yourself, but you might try using some drawing transformation methods - you may have to dig deeper into OpenGL. Now that you've given more problem details, maybe polygons isn't the only approach. Are you trying to map the touch coordinates to a certain shade in the man's arm, or to a particlar part of the arm? In the latter case, it might work out to just use points for the center of each part (bicep, tricep, elbow, etc.) and use an algorithm based on the distances of the centers to the touch point. This may involve additional geometry skills, such as dividing an area into regions based on such centroids.

The first thing that comes to mind is java.awt.Polygon.contains().

There are some ways you can get vector from a bitmap. I've used Visio by putting the image on one layer and tracing out the vector shapes in another layer, then writing some VB to export the shape vector data to XML. Do you have Adobe CS?

If a large part of the code is the Model, that is the business rules, logic, data conversion, etc., then there's a good chance that with some refactoring, you can get that part of the code to run on Android after some refactoring.

When the breakpoint fires, Eclipse highlights that line. From there you can inspect variables, the stack, etc. and step through the code.

Re: [android-developers] Re: Adapter fetches and parses RSS feed to get its data - best practice?
Interesting OOD question posed by the OP. If I understand the question correctly, I would say it depends In Android, the Adapter interface is a contract with a class that extends AdapterView. This is noticably different that the Adapter Pattern, which generally mediates between two incompatible interfaces. However, It's not too unusual to have a class that is otherwise unrelated to a AdapterView go ahead and implement Adapter or ListAdapter instead of having to add an additional adapter class to mediate. A possible objection may be that if other clients wish to access the model-ness of the class in question, they would have to access it via the Adapter interface. This is, however, not necessarily a problem as the class can easily expose other model-ness interfaces or be itself a model. As to single responsibility, I think a more important aspect of OOD with respect to the design of a class is cohesiveness. It's a question of degree.

Re: [android-developers] Re: Adapter fetches and parses RSS feed to get data - best practice?
I tend to agree with DanH as well as with Treking. Here's how I can agree with both: Best practices, object oriented design, design patterns, performance, all tend to become *anti-patterns* when used to extreme. For example, using a Singleton Pattern is considered a best practice by some developers, but they sometimes fail to understand when and where to apply it, creating unnecessary code. I think this is called the Golden Hammer Anti-pattern, to wit: thinking that a particular pattern or technique is universally applicable. my $0.02 -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: JPEG Image has a map
It just doesn't seem like a good idea to use Android Google map to display a plan view of an apartment and call out POIs within it. On my Droid, at full zoom-in, my apartment takes up about 1/12 of the screen. Also, if you placed markers for POIs within your apartment, when you zoom out, they just overlap and become useless. Is there really a compelling reason to mashup your floorplan with all the features and layers of Google maps? Is is just a specifc feature of GM you are interested in? What is that feature? I suggest you use a different approach, like simply displaying the floorplan as an image view, displaying markers on that, and providing whatever detailed callouts you want.

Re: [android-developers] Re: Proposal to Market Place
Good ideas, but as has been said, good luck with that. Some observations, if I may: 1) A developer shouldn't rely so much on ratings for feedback. Built-in bug reporting, email, a user network, a marketing site with user comments all provide a better dialog than the market's half-ass rating system. 2) How much do ratings really influence users? Users are either looking for ratings that support their prejudice (these are not your best users) or they are looking for a consistent pattern. Your best users understand how ratings can be gamed and can usually see through the nonsense. Also note that your pitch in the Android Market is likely going to influence users as much as the ratings. Do you have computer progammers write that, or do you hire (read: invest in) an experienced copywriter? 3) Ratings are just a half-assed way of letting potential users sort out apps on the market. Few, if any are actually objective. Imagine if the auto industry relied on a rating system like that. 4) I might also note that eBay uses ratings entirely differently. They don't rate the product. Perhaps that would be a better direction for the Android Market. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] What is the Android Sequence of Startup
There are a number of scenarios. The basic one is from the home page, but an app can also run when the device boots, wakes up, an alarm fires, or when another application sends an intent. The crux is the manifest which tells the Android OS what interactions the app is expecting and able to respond to. Note that an app doesn't really run. Its code gets loaded into a Dalvic VM and then the Andorid OS calls various lifecycle methods in the app's code. A lot of newbie developers stumble over this, thinking that an Android app runs just like a desktop application (even they are really subject to an event loop as well).

Re: [android-developers] SQLite Performance
I assume you appreciate the fact that just knowing SQL is not knowing how to optimize queries. I'm also going to assume that the read queries are the issue. Insert and delete queries are a whole different issue with respect to indexing. Indexes are indeed the primary means of optimizing SQL queries. I'm wondering if the create index command you ran on the PC is actually in effect on the Android device. If I'm not mistaken, you should be able to verify that the DB on the device actually has indexing enabled. Have you verified the speedup that indexing provided on the PC? If adding column indexing by itself is not effective, you'll need to look into the queries and the actual data patterns. Some queries are structured so that the DB cannot use indexes. See if sqlite has an analyze command for debugging queries. It will show the steps it would use to execute the query. If there's no step that uses the index (even if there is a column index) or if the index lookup is at the end of the steps, then the query is not making maximal use of the index. It's a bit of an art to coerce the query compiler to do it right and sometimes there are pitfalls in SQL that need to be understood. How many queries does you app use? Which one is the bottleneck?

Re: [android-developers] Re: guitar tuner
I may be wrong, but I'm wondering if taking the approach of FFT is going to be practical without dedicated hardware. The brute force approach amounts to doing a convolution computation for each sample, which could be millions of multiplies per second, depending on the bandwidth and Q factor required. But I'm pretty sure that with some clever math, that can be pared down considerably for a specific application. I have applied a digital filter approach for a prototype shake detector, realized as a band pass filter. This takes only one multiply for each pole and zero. Two or three concurrent band pass filters can probably do a pretty good job of implementing a single pitch tuner. A critical factor in this case is a precise sampling interval.

Re: [android-developers] Save and continue game
I think it depends on the amount of state, the complexity of the app, and how persistent the state is supposed to be. Saved instance state is a good place to start. In the Android activity model, you don't really exit an app. So unless the user does a force stop, the activity will be able to restore the state via saved instance state. The advantage is it's easy to implement, no need for files or DB. Shortcomings are data is lost on force stop, and I suppose update. So the question becomes what persistence does the game state need for various lifecycle events, such as: rotate screen, onPause/onResume, force close, update, uninstall, etc. You also may need to address how and when the game state IS reset. hth -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Is it a UNIT Test or an Integration test?
You've raised a good question. It's correct to to say that a unit test does not involve all the classes of an application. Unit tests are also supposed to run very quickly. We also usually don't include the GUI in unit tests. Neither external web services. In Android, though, we have a bit of a problem. To really run even by the book unit tests, we'd have to either run them on the JVM or the DVM. In the first case, we would be using .class files, in the latter case, .dex files. But I don't know if we have DVM for anything but the emulator or the device. And the emulator's DVM tends to run slow. Hmmm.

Re: [android-developers] Re: write to xml file
Just for a clarification. The string.xml file is a source file, it's not part of the apk, hence it is not available at runtime. Instead, the bulid process translates it into the R class file, which allows the application to quickly access the strings directly via Java instead of parsing it at runtime. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Where is the UI state information (used in super.onCreate(Bundle savedInstanceState)) stored ?
On a rooted phone, you ought to be able to kill the Linux process. Just finish or force close may not be secure since the Android OS lazily reclaims processes that are no longer in use. Although on a non-rooted phone this is not an issue, since the Android OS relies on Linux process security. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Return to my application when back key is pressed from native dialer
Thanks for clearing up some of those questions. I have some hypothesis at this point. First, is your activity calling finish somewhere? That would explain why it's not there when the user presses back in the dialer. Have you tried a breakpoint in the activity's onResume method? Perhaps it is being called after the back button, but is doing something weird. The other is perhaps there's a launch flag in your activity that causes it to be removed from the activity stack once the dialer activity is started. hth -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] When is the appropriate time to use separate processes?
I think the easily killable angle is rather odd. What kind of an app do you have in mind? I've used the Android Intent architecture to hand off tasks to activities in other apps/processes. For example, to take a picture, open a web page, or dial a number, my apps don't have to implement that code, they just send an Intent and let the Android OS find an activity to do it. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Return to my application when back key is pressed from native dialer
The behavior of the code you posted should be to return to your activity when the user finished the dialer activity by pressing back.

Re: [android-developers] Re: Return to my application when back key is pressed from native dialer
I'll have to check the code I use. But perhaps the problem is you're not giving a number or try using Intent.ACTION_VIEW instead of Intent.ACTION_DIAL. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Return to my application when back key is pressed from native dialer
I'm not following you very well. I assume you mean that if you add the phone number, then the back button does take the user back to your activity, but without the phone number, the back button takes the user to the home screen. I also assume that what you mean by native homescreen is the same as when the user presses the home bvutton on the phone. If that's the case, I think you should expalan your use case better. If the dialer behavior for the back button is different when a phone number is provided or not, that might by an Android OS issue, or an issue in your use case. I also don't understand you're introducing a possible issue with using a dialog. AFAIK, you would have to call startActivity(Intent) in the activity, after the dialog has been closed. You also have not indicated what phone and API level you are having this issue on. But perhaps if my assumption is correct, you can get the back button to work correctly if you supply the dialer with a phone number? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Service onCreate is asynchronous
I can't help but think this is just a misunderstanding or failure to RTFM. The method ref says This defines a dependency between your application and the service.
