On page 12 of the sample the string “name” key got hyphens in them instead of a underscore. (test-image_title)

"android.developer.com" should be "developer.android.com"

Title reads "Doanload and install the SDK". Change "Doanload" to "Download".

Title says 'Doanload' instead of 'Download'

Text states 'Press "Instal Selected"' Change "Instal" to "Install".

Screenshot display does not match that created following previous instructions. Screenshot window-title bar displays "5554:default". However, instructions (on page 23) create a window which actually displays "5554:standard". Screenshot app displays "Hello World, AndroidLove!". However, instructions (on page 18) create an app that displays "Hello World, HaikuDisplay!".

In the first paragraph, "Now that you have an emulator configuration set up, run the app again. Run it the same was as before by pressing the play button in the toolbar." The sentence "Run it the same was..." Should be "Run in the same way..." Change "was" by "way".

The second line says Navigate to /res/layout/main.xml in the "exlipse" instead of "eclipse" package explorer and ....

Purple folder called "layouts". Change "layouts" to "layout".

Seems to be a spurious single-backquote (grave, or ` ) after the word "So".

Text states "Right below layouts in the res folder ..." Change "layouts" to "layout".

Purple folder called "layouts". Change "layouts" to "layout".

Text states "Navigate to the main.xml file in the Eclipse package explorer." Change "main.xml" to "strings.xml".

read as Activities describe what your app

Fifth bullet point states "Layouts are defined in XML and you can find them in /res/layouts." Change "layouts" to "layout". Six bullet point states "Values (like strings) are defined in Android Resource XML files. They can e found in /res/values." Change the solitary " e " to " be ".

Says" Its like harding cattle. Harding should be herding.

Text reads "HIde the haiku when the ap loads." Change "HIde" to "Hide". Change "ap" to "app".

Text reads "You can find it under /res/layout.main.xml." A "/" at the end of "layout" has been replaced with a "." Should read "You can find it under /res/layout/main.xml."

"Open main.xmlby by" should be "Open main.xml by"

The sentence reads "Open main.xmlby double clicking ...". The sentence is missing a space after the file name: "Open main.xml by double clicking ..."

Text reads "You’ll the first View defined in the file is the Button you just added!" Add "see" between "You'll" and "the" (i.e "You’ll see the").

Missing word, "where the button is going render." Should be "where the button is going to render."

Text states "... TextView displaying the hauki and the Button ..." Change "hauki" to "haiku".

Text reads "You could remove the TextView and it back once ..." Add "add" between "and" and "it" (i.e "and add it").

Text states "If you know the class you're looking for, but now the package, you can type it in here to search the documentation." Perhaps change "now" into "not" ?

the sentence should read "This area lists all of the packages in.." instead of "This area lists all of the packes in..."

2nd line should read "looking for, but not the package," instead of "looking for, but now the package"

Give is a value of onLoveButtonClicked to be descriptive of what the Button is supposed to do. Change "Give is a value" to "Give it a value"

This example of folder hierarchy does NOT match what you get from following the instructions in chapter 1. The actual hierarchy is: AndroidLove -> src -> android.love -> HaikuDisplay.java

Should say onLoveButtonClicked instead of onLoveVuttonClicked. on paragraph: "Let’s add the onLoveVuttonClicked method to AndroidLove now. Once this is done, we can run ..."

The paragraph starting "The new onLoveVuttonClicked method..." should be "The new onLoveButtonClicked method..."

But you action code is defined in Java in the AndroidLove Activity. Change "But you" to "But your"

sentence: To solve this, Android generated a special called the ‘R’ file. There's a missing "file" word.

The text assumes the existence of some "com/headfirstlabs" path/package while the reader following the book didn't create any.

"an R file constant will getgenerated." missing white space after "get"

The next to last bullets need some editing. From: "to use Use the android:onClick property on Button to add an action method. That action method ..." Possible to: "Use the android:onClick property for the Button object to add an action method. That action method ..."

I can’t want to see it working! Change "want" to "wait"

But It’s better leave out spaces 1. Make "It's" lower case. 2. Add "to" after "better"

Select the latest platform you have installed (2.3 at the timeof this writing Change "timeof" to "time of"

test_image_title, test_image_description, test_image_date use underscore between "test" and "title", while on page 90 they use hyphens ( test-image_title, test-image_date, test-image_description ).

You were to used the ScrollView to make the entire screen scroll. Change "used" to "use"

"afterprocessFeed() returns" is missing a space (ie, should be "after processFeed() returns"

Using R12 SDK/emulator against Android 2.2, no IOException is generated. The only thing returned is a vague "permission denied". Of course this never gets printed to the log because of the try...catch in IotdHandler which silently ignores the exception and continues as if nothing happened. It wasn't until I changed the code into URL dataUri = new URL(url); InputStream inputStream = dataUri.openStream(); reader.parse(new InputSource(inputStream)); } catch (Exception e) { String error = e.getMessage(); System.out.println(e.getMessage()); } and ran it through the debugger that at least that much was visible. A watch on the exception shows it to be a java.net.SocketException with no further information.

In the 4th line of th 3rd paragraph instead of "requsts" it should be "requests"

You can specity the permissions your app needs using a group of permission constants in AndroidManifest.xml. Change specity to specify

There are a bunch of different permissions that you can ad to your application. Change ad to add

With the adjustViewBounds properts upated in your layout, run the app again. change properts to property change upated to updated

It’s a good practice to break your app down into small development pieces Probably should get rid of the "a" after "It's"

Let’s build the button bar as a standalone layout and then add it the app’s current layout. Should this sentence have a "to" between "it" and "the" to look like the below? Let’s build the button bar as a standalone layout and then add it to the app’s current layout.

Encapsulating parts of your fullscreen layout into separate smaller layouts can be a good way to organize layouts. change "fullscreen" to "full screen"

"Use properties to fune-tune the layout" should be "Use properties to fine-tune the layout"

layout-width and layout-height boxes, second box should be layout_width

In both of these pages and anywhere else in this chapter that the magnets are used with the "layout_xxx" attribute, the magnet incorrectly uses a dash instead of an underscore. This is true for some of the values as well (i.e. wrap-content instead of wrap_content).

page has been erroneously duplicated and should be removed; page exists in its correct position at page 133

Capitalize the third sentence starting with "you"

You should have also dismissed when dialog once the work is completed. Change "when" to "the". I'm guessing "once the work is completed" should be in the past tense.

In the sentence: "The UI thread has a queue of work, and it continually gets the mot important chunk of work to process." It should say "more" instead of "mot".

It should say "Repaint" instead of "Repain" in reference number 2.

The second task has a label of "Pperform layout". Should it be "Perform layout"?

Task 1 reads "This expensive call on call on the UI thread keeps repaints from happening." "call on" is repeated twice.

On Task 2 change "Repain" to "Repaint"

possessive apostrophe used for a plural. "You can populate your ListView’s" should be "You can populate your ListViews"

"You should have completed the getView method blow" should be "You should have completed the getView method below"

"When working on a multi-screened app, always start with your post important use case." should of course be "When working on a multi-screened app, always start with your most important use case."

"make your own Android context men- the menu that pops up when" should be "make your own Android context menu, the menu that pops up when"

"ExitText" should be "EditText"

RESULT_CANCELLED should be RESULT_CANCELED

The request code passed into startActivityForResult is returned along with the request code set before finish was called. I think that it should be: "The request code passed into startActivityForResult is returned along with the result code.... "

The last sentence of the first paragraph states "Then using a database API, your app would connect to the database and query or addsdata to the database." This looks like it should be "add data" not "addsdata".

chapter # listed in the page footer is incorrect. Should be 9 rather than 67.
