Android :: Where Should Report Mistakes In Documentation - Source Says CountdownTimer
Jun 14, 2010
This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting.
On this page within the example source code, the source says "CountdownTimer" on line 1 when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time.
Is this where documentation bugs are submitted, and if not, where should I go to request the fix?

If you look at the Android documentation about how to implement a List View and populate it you will notice that they only teach you how to do it in Java extending ListActivity instead of the normal Activity, but how would the same code (layout and populate the list) using XML layout files and extending Activity?
I'm asking this because I want to implement a RelativeLayout and add more elements to the screen where the ListView is with more flexibility than using .inflate() and addHeaderView()/addFooterView().

After I Bind to a service inside the method I start a CountDownTimer. The problem is that the timer does not start counting down. I have gone through with the debugger and sure enough it is executing the method that starts the Timer.If I use a button to start the timer it works! What could I be doing wrong?

I'm extending the CountDownTimer class to obtain some custom functionality .In onTick() in case some conditions are met I call cancel() , expecting that will be the end of it, however the onTick() callback gets call until the the count down is reached . So how to prevent this from happening ?

My activity has a simple menuItem that start a counter...the counter is stored in a field of the activity
the problem is with the "back button" after closing the activity (back button), the timer (as in my intention) continues, and restarting the activity behave correctly by reshowing the timer...but I lost the reference to the counter and so I cannot stop it.
Following there is a part of the code of the function:

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...

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 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?

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?

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?

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.

Here's a snip that successfully reads off, to Eclipse LogCat, the height and width of the .PNG on the SD card:
import android.app.Activity; import android.os.Bundle;
import android.util.Log; import android.graphics.Bitmap;
import android.graphics.BitmapFactory; import android.os.Environment;
//...
Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory().getAbsolutePath() + "/sample.png");
int width = bmp.getWidth(); int height = bmp.getHeight();
int[] pix = new int[width * height]; bmp.getPixels(pix, 0, width, 0, 0, width, height);
int R, G, B; for (int y = 0; y < height; y++){ for (int x = 0; x < width; x++) { int index = y * width + x;
R = (pix[index] >> 16) & 0xff; //bitwise shifting G = (pix[index] >> 8) & 0xff; B = pix[index] & 0xff;
// [This is where I'd put it. But I can't get a red line off the editor when I do anything.] } } Log.v(TAG, width + " " + height);
I can't for the life of me use Log.v() to report the value of R or G or B. Everything I'm doing draws a red line under v or something when I try. I've tried toString() and everything.
