[android-beginners] Docs: AsyncTask
AsyncTask is Genius programming but in the docs appears to have incomplete information. There's not enough to understand how it works. -- "onPreExecute(), invoked on the UI thread immediately after the task is executed." (I think this should be Before the task is executed.) "Not all types are always used by am asynchronous task. To mark a type as unused, simply use the type Void:" (then it has this as an example - which has nothing to do with Void.) "private class MyTask extends AsyncTask" AsyncTask http://developer.android.com/reference/android/os/AsyncTask.html + Juan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Downloading Android
I just had serious problems in downloading the Android Plugin as well as the Google Apps Engine Plugin for Eclipse using "Eclipse Classic 3.4.2 (152 MB)". I think there's an issue with WST, but it's not clear how to download it to get that dependency. It's really messed up. I downloaded "Eclipse IDE for Java Developers (85 MB)" with all the dependencies installed and everything including Android installed quickly and cleanly. Perhaps "Eclipse IDE for Java Developers (85 MB)" should be the recommended version.

In this Order: 1. The Java Tutorial http://java.sun.com/docs/books/tutorial/ 2. Android Documentation http://code.google.com/android/documentation.html 3. The Busy Coder's Guide to Android Development http://www.amazon.com/gp/product/0981678009/ Just learn the basic Java. Familiarize yourself with the Android API.

[android-beginners] WikiNotes & WikiNotes Articles
After a long long time I've come to the conclusion that WikiNotes is best (for me) for learning Android. It's a fabulous, genius App together with the tutorial articles for learning Android. The Android Developers Blog has the tutorial articles with promises of many more. However, some time ago they just stopped. I also think there were 3 articles and now there's just 2 articles on WikiNotes. "The full description of the ContentProvider and what it does will span a couple more articles as well, because there is a lot to cover." http://android-developers.blogspot.com/2008/03/wikinotes-for-android-routing-intents.html Frankly, I don't really know why it's so great in learning Android. I can just perceive it intuitively that it indeed is. The power of the intent structure in android does show itself greatly though. I can see that a person would not know how important WikiNotes is for learning Android without trusting it to be so. But more articles written by Dick Wall would be very helpful. And then highlighting WikiNotes as almost fundamental to learning Android. - Juan T. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] Re: AIDL Concept!!!
Sometimes you need to communicate between different Processes. Processes are like threads, but higher level, and they encompass applications. Conceptually, the way you do this communication is through a Binder using the currency of the Parcel. The Binder is the main concept in this communication. AIDL (Android Interface Definition Language) is a special tool that enables you to perform this communication between processes (usually meaning applications). - Juan T.

[android-beginners] Re: ANdroid coding guidelines
I recall Dan Morrill at Google I/O saying that just as in other disciplines one doesn't know the tool very well, but knows what tool needs to be used at what time. In Android, when you need the Location API, then that's when you delve into the intricacies of it and not before. It's good to get a grip on the Android API, but I think Android is especially rich with camera, location, etc. that you have to deal with one thing at a time. You need to know Java completely though. You have to know XML because you'll eventually use it in one way or the other. If you don't use it, it's still very helpful to know. - Juan T.

[android-beginners] Re: org.apache.http tutorial?
Thanks. It says here. "the HttpComponents may be of interest to anyone building HTTP-aware client and server applications such as web browsers, web spiders, HTTP proxies, web service transport libraries, or systems that leverage or extend the HTTP protocol for distributed communication." http://hc.apache.org/ Now I think some people are using Apache http libraries rather than the JAVA version. But this official paragraph appears to say that you only need to use the Apache version if you are building a web browser or a spider! So what's wrong with the JAVA version? In what way would the Apache library be better? Why is Photostream using tons of different classes in the Apache library just to get flickr photos? - Juan T.

[android-beginners] Re: Style vs. Styleable
android.R.styleable appears to say these things are able to be styled and here's how they can be styled. They describe "Attributes that can be used with a..", etc. android.R.style maybe the real issue. Both style and styleable have values that can be assigned to set a value no? But android.R.style is a combination of things. There are themes, text appearance and widgets. These are all very different things. So it's difficult to see just what style is. - Juan T.

Hello Farooq, There are no applications. The main component is the Activity, and there are Services, BroadcastReceivers and Content Providers. All these are part of the Flow. Your app is using components you didn't create. And within those components is Flow as well, such as Activities have onCreate() and onStart() and onPause(). So you have to have patience and understand things little by little. - Juan T.

[android-beginners] Re: Difficult Paragraph on Tasks
On the next page - "Application Life Cycle" there's this sentence. "A process's priority may also be increased based on other dependencies a process has to it." http://code.google.com/android/intro/lifecycle.html I think it should say "dependencies the process has" or at least "dependencies a process has". I know this is incorrect because I understand what it's trying to say. The problem for me in going through many other sentences, is that I don't know what they're trying to say. So I'm definitely being confused because chances are there are mistakes (grammatical and semantic) there as well. I think this is a serious issue because if I don't understand it, at least many others don't as well, and the biggest obstacle to great apps is the complexity of the platform. And the only real solid gateway to understanding what's encapsulated in these pages, is what's written in the page themselves, how it's expressed, etc. - Juan T.

[android-beginners] Re: Difficult Paragraph on Tasks
I request that this whole page be rewritten. http://code.google.com/android/intro/appmodel.html This is really important and complex things on tasks and such as it is now, the complexity of it is made more complex by grammatical and semantic errors. I've only gotten halfway through and here's what I call a semantic error. "However, if the NEW_TASK flag is being used, then the affinity will be used to determine if a task already exists with the same affinity." I think this should be "determine if THE task already exists". In the previous sentence that conceptually compares itself, THE and not A is mentioned. This page is probably very important compared to the rest of the docs given the complex nature of tasks and stacks. Maybe it needs visual diagrams. But I think it needs to be rewritten with more weight on making the complexity more easy to understand. - Juan T.

[android-beginners] Difficult Paragraph on Tasks
"In addition, you should only use the new task flag if it is possible for the user to navigate from home back to where they are and launch the same Intent as a new task. Otherwise, if the user presses HOME instead of BACK from the task you have launched, your task and its activities will be ordered behind the home screen without a way to return to them." http://code.google.com/android/intro/appmodel.html, Tasks Maybe I need a Ph.D to understand it. :) Or maybe there's a word off here somewhere. How can one navigate from home back to where one is at the moment? Why wouldn't I be able to return to the task/activities if the home screen is in the way? But really since I don't understand the first part, the second is not going to get me anywhere anyway. :) There must be some grammatical error here. Here's a grammatical error in the paragraph before which makes the whole meaning of things unclear as well. And maybe we need visualization in these things. "A task, then, from the user's perspective your application;" - Juan T. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.

[android-beginners] What is an Image?
What is a mountable disk image? What is a ram disk image? An sd card image? Wikipedia http://en.wikipedia.org/wiki/Disk_image says it's a disk image is a single file representing a data storage medium, etc. So is an image just a single file? How is this file different from any other? - Juan T. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
