So I'm following the steps on developer.android.com and I can't get past this. It says my Android support library is out of date so I click Install/Upgrade and it doesn't work. It says it fails to create that path. Also when I try to download the extras in the Android SDK it just says access denied. Am I doing something wrong? Is there anything I can do to fix it?

I've been trying to do just that on a fresh install of Windows 7 on and off for the past couple days. The installer refuses to recognize that I have JDK installed.

My PATH variable has "C:/Program Files/Java/jdk1.7.0_07/bin" in it, just for good measure, I've created a JAVA_HOME variable with the same thing. When I'm in any windows command line and I type "java -version" it outputs

code:

java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

So what gives? All my searching only gives me results where people say "Add java to your PATH variable" and "create a JAVA_HOME variable."

Is there some issue with JDK 1.7.0_07 and the newest version of ADK? I've never had any trouble installing it before...

Is it just me or is Eclipse terrible for debugging? I get an error like this in LogCat and I'm left feeling as though there should be more information attached to it to help me identify which part of the cited line is faulty:

code:

02-22 08:50:32.832: E/AndroidRuntime(3005): Caused by: java.lang.NullPointerException
02-22 08:50:32.832: E/AndroidRuntime(3005): at com.example.testapp.FragmentSearch.onCreateView(FragmentSearch.java:59)

The error points to this line of code:

Java code:

db = new DBHelper(getView().getContext());

According to the error, db or getView().getContext() could be the problem. Based on my experience, I'm probably using getView().getContext() incorrectly, but you wouldn't know it just by looking at the LogCat error output. Having done a few pet projects with C# in VS before, Eclipse's debugging feels lackluster. Am I just not using it correctly? Are there some better tools or settings I can implement that would improve the quality of LogCat's error logs?

And would getView().getContext() return null from within a fragment? I'm trying to pass along the app's context to the helper class from within a fragment that will display the results of a SQL query.

So they've changed the way they count device versions. Before it was based on devices' automatic check-ins over a 2-week period, so basically every device out in the field. Now it's based on devices where the user actually opened the Play store.

I can't tell if this is goalpost-moving or if this actually is a better metric. It does seem to more accurately reflect the user base of one of my apps, for whatever it's worth.

Hey now, I didn't phrase it nearly so harshly at the keynote. >:/ though I agree, it was totally dodged. Sad. I hope that the questions get them to think harder about the problem, at least. That was my intention, anyway.

So here's a question: how do I hook the default share mechanism in Android? I know it's possible because apps like Andmade Share do it, but I can't figure out how to. Googling around just seems to recommend hooking android.intent.action.SEND, but that doesn't seem to do anything.

Glimm posted:

You're just trying to share stuff to other applications right? What exactly are you trying?

This is probably a good place to start: http://developer.android.com/training/sharing/shareaction.html

A couple of Android developer advocates were asked about this on G+ or something, I saw it recently. Their answer was that if you're already using ABS then there's no great requirement to recode your app, but for new apps you should probably use Google's version since you know it'll keep working in the future.

Can I reference an existing string in strings.xml when I define another string? For example:

XML code:

<string name="foo">Foo</string>
<string name="bar">@string/foo + Bar</string>

I want the "bar" string to return "fooBar" right now or "ShittyBar" later if I change the value of the "foo" string to "lovely".

On developer.android.com have I been able to find information about how an icon should look if it is enabled or disabled, but I have not been able to find information about what if it is selected; i.e. I want to toggle a feature and I want the icon to look the official way a toggled icon should look, whatever that may be.

Thanks for the information. I don't get what you mean with "maybe a toast" though.

Complete speculation, but it could be the text glyphs being pushed to the hardware rendering pipeline, but the stencil masks are getting lost along the way. They're all basic quads, the right colour and shape and position, so they just might not be getting composited properly.

If that's the case I'm not sure what you could do about it, it's an internal thing right? If it only happened once I'd chalk it up to a fun glitch

So I have an app that authenticates the user with a third party website using account information that the user supplies. Right now I am storing their username/passwords in plaintext on the app's internal file storage so they don't have to supply this information every time the app connects to the website. The files are supposed to be private to the application, but I would still like to encrypt the user information because of obvious reasons.

Hashing here isn't going to work, because the app has to post the unencrypted passwords to the website, so what is going to be the best way to encrypt and decrypt the data to and from storage? I don't have much experience with cryptography, doubly so with doing it in the context of an android app, so any help would be appreciated.

Is there a way to get a method invocation from the OS, when a user uninstalls the app, so that relevant files created on the disk can be deleted (like an uninstaller in windows would)?

Stack Overflow posted:

Sadly android at the moment does not give you a possibility to perform code at the moment your app is uninstalled.

All the settings that are set via the SharedPreferences are deleted together with everything in the Aplication Data an Cache folder.

The only thing that will persist is the data that is written to the SD-Card and any changes to phone settings that are made. I don't know what happens to data that is synchronized to the contacts through your app.

I'm developing a game in HTML5/JS and want to port it to Android. This should be pretty straight forward (putting the html in asset and load it with Webview) but will my HTML/js-code be visible for the end user (I guess yes?). If so, is there any way to get around it? If not I might considering porting my code to native android code instead.
TIA

Material Design compatibility guide posted:

The material theme is only available in the Android L Developer Preview. To configure your app to use the material theme on devices running the Android L Developer Preview and an older theme on devices running earlier versions of Android:

1. Define a theme that inherits from an older theme (like Holo) in res/values/styles.xml.
   
2. Define a theme with the same name that inherits from the material theme in res/values-v21/styles.xml.
   
3. Set this theme as your app's theme in the manifest file.

ListViews seem to be unnecessarily complicated. Anyone have a good article explaining the best way to get a bunch of structured data (in my case some JSON) into a ListView with multiple text/image items on each line? I'm guessing I need a custom View which inherits from whatever a ListView displays?

stackoverflow posted:

I have a Preference activity which uses a List Preferences as defined by my XML file. How would I set the summary of the list activity to the value that is selected?

Thank you!

stackoverflow answer posted:

The simplest way to do this is just to have Android do it for you. Assuming you want the summary to match the selected value, you can simply set the summary of the ListPreference to "%s".

Android will replace %s with the current string value of the preference, as displayed by the ListPreference's picker.

I spent far too much time mucking about with SharedPreferences listeners before I discovered this. As a bonus, the list's summary will be set correctly when you enter the activity.
