Android :: How To Get Complete Droid Documentation
May 12, 2010
I am Graduating in Computing Science, and my final project is a complete research in Android's Platform, with a development of an application. I would like to know how can I get the complete documentation, beacause my research is very thorough, and I relly on books and documentation. The current site I am reading about methods and activities, etc is the Dev Guide on developer.android.com. I don't know if is it complete there. But if you know, could you please show me the link, or tell me how to get it?

Trying to get my head around the specific ins/outs of the Looper object and how it interacts with Threads. Documentation is rather scant on this topic. This is one of those topics that is obvious to the Android core team, but to the rest of us, it's not so obvious.
Can someone point to better documentation or give a more complete account of Looper:
1. What is looper.
2. How does the Android phone use Looper to coordinate message handling?
3. What do I need to do when I get the "Can't create handler inside thread that has not called Looper.prepare()" message?
4. How do I use LocationManager.requestLocationUpdates with Looper, and why does this call require a Looper object?

I'm using Eclipse with the Android SDK. I installed The SDK platform Android 1.6, API 4 using Android SDK and AVD manager, but I can't find the corresponding documentation in the list of the available packages (there's only the doc for the API 7). Where can I find it?

A small notice here to say I found an error in the documentation, when building a radio button context menu in XML.
On this page, in the Menus section, under 'Elements and Attributes' for the <group> tag. http://developer.android.com/guide/topics/resources/available-resourc...
"checkableBehavior - Whether the items are checkable. Valid values: none, all (exclusive / radio buttons), single (non-exclusive / checkboxes)"
This should actually be the other way round: * all (non-exclusive / checkboxes) * single (exclusive / radio buttons)

I've been looking around for this for a long time but can never seem to find it in the Android documentation. There's all sorts of advanced things I see, but I can never find any solid documentation - there's the shapes package, but it provides no insight on how to use them in xml. The best I can do so far is finding other people's examples.
Is there some magical documentation that exists for the XML shapes?

Is there any Android browser reference/documentation for Web app developers? Something like Apple's Safari Web Content Guide would be fantastic.
I am exploring options to make Android Web app more native-like.

Several Droid users have reported that my app's entire database just destroys itself randomly after a few days or so. This seems to be specific to the Droid. I'm at a loss. My app has a service that runs in the background to display notifications, it also supports widgets. Both of those (and the app itself, of course) access the database, and I marked every accessor to the database "synchronized", just in case. Any remote idea what could cause the entire database to just vanish?

Is there a way to find out the final location of my animated "object" after the animation? Let's say I am animating an ImageView with location in parent as (0,0 - 20,20) using TranslateAnimation and ScaleAnimation over 1 second with setFillAfter(true).
How to I find the final location of this "object" (since the View location itself does not move)? I need to continue the animation from this point based on an user input.

This is my first S/O question.
I'd like to know more about porting C applications to native ARM for use on Android devices.
I can make simple programs using the prebuild toolchain which comes with the source, but how can I use this toolchain with applications which are more than one file and require configure and make?

I noticed WebView seemed to have some new methods I didn't remember from before. Unfortunately I can't tell exactly which ones are new, without actually trying them and waiting for the SDK to catch the mistake.Could the docs please state in which API release a method, class, interface, enum etc was added? This is pretty fundamental to know when trying to figure out how to implement something.

I have been using the Android documentation for a few days now, and it is quite good and easy to read. Apart from that I noticed that I missed something, and now I found out what it is: Examples and comments.
If you look at the PHP documentation (e.g. http://www.php.net/manual/en/function.substr.php for the PHP substr() function) you will see many syntax-highlighted examples and comments by users.
Of course there are examples in the Android documentation, especially in the Dev Guide category - they just are not at the right place if one searches the reference for a specific method or functionality. What do you think about this?

The documentation does not make the interation between onUpgrade() and onCreate() clear.
When implementing onCreate() should this create the database at version 1, assuming that onUpgrade will apply all of the patches to bring it up to version x (lets say version 5 for example)? Or should onCreate build the latest version of the database, and onUpgrade is only used to upgrade legacy clients.
I kind of prefer the first, because it effectively means that the same SQL is executed for everybody. Whereas the second options means that there is a potential for onCreate to build something slightly different to the succession of patches built by onUpgrade.
I can always make onCreate call into onUpgrade, however, this is the kind of implementation detail that should go into the javadocs...

I've had my Droid since it came out,but have never understood this whole "rooting" thing. What are the pro's/cons of rooting my Droid? Are ROM's free?Are they easy to install? Will this crash my phone in any way? Can I unroot it if it causes problems? Im debating if I should root my Droid or not.

I'm trying to find some official android documentation that discusses sleep mode, with a focus on issues that might be of relevance to app developers. For example, things like:
1. What causes a device to enter / exit sleep mode?
2. How are running processes impacted when the device enters sleep mode? (I believe they continue to exist, but don't execute because cpu activity is suspended. When the device wakes up execution picks up where it left off?)
There is some good info in the API docs for PowerManager and WakeLock, but nothing there that explicitly states what I have assumed in point 2 above. Are the above issues (and any other relevant issues) documented anywhere?

Does anyone know how to integrate with the new Gallery3D app (cooliris android gallery)? I want to launch that app so it shows the thumbnails for only a specific folder.
For example, say my app downloads images from my server and stores them in a folder on the sd-card (/sdcard/myapp/image-cache/someid/*). I'd like to be able to do something like the following:

On the documentation page "Developing on a Device" http://developer.android.com/guide/developing/device.html there may be two errors in the section "Setting up a Device for Development."
First: To run (not debug) an app on a device, you do not need to set the "debuggable" attribute in the manifest. The documentation implies this is a requirement. It may be a good idea, but, when stepping an absolute beginner through the process of running their first app, this is an unnecessary detour.
Second: The instructions for turning on USB debugging don't mention the Settings activity: "On the device, go to the home screen, press MENU, select Applications > Development, then enable USB debugging."
The first error is more of a quibble, but the second seems to be actual misinformation that may puzzle a beginner, wondering why there isn't an "Applications" item on the Home app menu. In most cases this should go "Settings > Applications > Development > USB Debugging," and the menu key is not involved.

I am working on building an android app but I'm nothing that my SQL operations are taking forever to complete
I have profiled the app to narrow it down to the act of moving the Cursor to the first row of the result set for a simple select query (only returning 1 row where I'm testing it to eliminate the size of the result set as a problem.
Are there any better options for moving to the start of the result set?
edit:
some code...
this runs 3 times and i have time it to approximately 2 secs for all the rest of the code or over a minute with this in.
i have also run just the rawQuery statement with out the move to first and its takes bout 18 secs so im looking at the worst part of the code first.
