Say I want to define that an URI such as: myapp://path/to/what/i/want?d=This%20is%20a%20test must be handled by my own application, or service. Notice that the schema is "myapp" and not "http", or "ftp". That is precisely what I intend: to define my own URI schema globally for the Android OS. Is this possible? This is somewhat analogous to what some programs already do on, e.g., Windows systems, such as Skype (skype://) or any torrent downloader program (torrent://).

I want to know where the xml schema is stored in Android, which is the schema for androidmanifest.xml file. In androidmanifest.xml file I have the namespace as "http:// schemas.android.com/apk/res/android" . Is this stored locally or remote anywhere?.

The Android XML Schema is declared in the xml files as being at "http://schemas.android.com/apk/res/android". Since this URL is not found, how does Android validate the xml attributes that are in the Android namespace? I am guessing the schema file comes bundled with the SDK, in which case where is it located?

I'm an android developer trying to use the javax.crypto package to encrypt/decrypt my SQLite database backups when I put them on the SD Card.That way, they can't be read while they're in the publicly accessible file system.I can encrypt/decrypt the file just fine, but I have no idea how to tell if the user input the right key or the wrong key. An incorrect key just returns a more jumbled file. I need a way of validating the user's password without storing it on the device (since they could be importing to another device).How can I check to see if the file has been successfully and correctly decrypted?

I need to do form input validation on a series of EditTexts. I'm using OnFocusChangeListeners to trigger the validation after the user types into each one, but this doesn't behave as desired for the last EditText. If I click on the "Done" button while typing into the final EditText then the InputMethod is disconnected, but technically focus is never lost on the EditText (and so validation never occurs).

If I want to enforce a maximum length of input in an EditText field, I can use the maxLength attribute. But if I want to enforce a minimum length (in my case, simply non-blank), I find no corresponding minLength attribute. I've also looked at the various 'inputType' attributes (phone, password, etc) but I don't see anything like 'required' or 'non-blank'. I can't believe this would require a custom input filter; it's more likely the answer is so obvious it just doesn't get written down in the form I'm asking the question.

Does anyone have sample code to validate user entered text in preferences? For example, I have a EditTextPreference for user to enter an email address. I'd like to validate the format of email address entered and pop up an alert dialog if the format isn't correct. Anyone have any sample code for this?

Is there any Java validator libraries i can use to validate text input from an android app?
i know that in spring there are validators for various different types such as checking if a value is a int, if a value is a valid email, etc etc.
Anything similar in core Java or even android?
cheers in advance. i don't want to re-invent the wheel if its already been implemented. i could always sue Java reg expressions to construct my own ones but was wondering if their was one done specifically for email formats.

Whilst trying to update through the Android AVD Manager, I receive the message:
"No suitable XML Schema Validator could be found in your Java environment"
It therefore can't parse the repository.xml and I can't download any updates.
How can I get rid of this error? I am guessing it might be caused by GIJ being the default Java implementation on my platform (Debian), however I have also installed the Sun JRE/JDK now.

What's the best practice to validate an e-mail address (e.g. from an user input field) in Android? org.apache.commons.validator.routines.EmailValidator doesn't seem to be available. Are there any other libraries doing this which are included in Android already or would I have to use RegExp?

Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?

We are suddenly unable to install our app on G1 developer phones with 1.6. Works perfectly on emulator. When installing the app we get:
Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE Please check logcat output for more details. Launch canceled!
And logcat:
PackageManage: Couldn't copy package file to temp file.
What does this mean? We checked that there is actually room enough on the phone.. We tried reverting the code to a revision that worked previously, but are getting the same error.

I have some reference data in a text file (~5MB) that I want to use with might android application.The file is of the format:
1|a|This is line 1a
1|b|This is line 1b
2|a|This is line 2a
2|b|This is line 2b
2|c|This is line 2c
What I want to know is the most efficient way (less memory, fast, size etc.) to use this file within my application.
a.) Should I save the file as a raw resource and open and read the whole file whenever I need a certain line.
b.) Should I convert the file to XML and use XPath to query the file when ever I need to look up a value
<!--sample XML -->
<data>
<line number="1">
<entry name="a">This is line 1 a</entry>
</line>
</data>
c.) Should I just copy & paste the whole file as a static string array in the application and use that.
[EDIT] I will also need to search this file and jump to arbitrary keywords e.g. "line 1a".

I have a large bitmap (say 3888x2592) in a file. Now, I want to resize that bitmap to 800x533 and save it to another file.I normally would scale the bitmap by calling Bitmap.createBitmap method but it needs a source bitmap as the first argument, which I can't provide because loading the original image into a Bitmap object would of course exceed the memory (see here, for example).Is there a way to read a large image file with 10MP or more and save it to a new image file, resized to a specific new width and height, without getting an OutOfMemory exception?I also tried BitmapFactory.decodeFile(file, options) and setting the Options.outHeight and Options.outWidth values manually to 800 and 533, but it doesn't work that way.

How come this is the only file manager on the market (that I've found... I went through quite a few) that can open an HTML file from your SD card? I was a loyal user of Estrogen until I found that it couldn't.

I'm writing a bitmap editor. Each document consists of about 3 bitmap layers and documents are, at the moment, saved as a custom file with a .bme extension. These files can be converted to standard jpg/png files by rendering each bitmap on top of one bitmap and saving the latter. I need some way for the user to be able to select .bme files they've created already. Is there anything in Android that can make this easier for me? The only option I can see is to write an activity that creates a list view and write a list adapter that looks for .bme files on disk i.e. a copy of the standard "Media Gallery" app that works for my .bme files. The list adapter will either have to generate a thumbnail preview of the image to show to the user or I'll have to package such a preview in the .bme file when they're created. This is the only option I can think of. I thought I'd ask in case there is more Android friendly way of doing this. For example, can you add custom file support to the "Media Gallery" app?

I accidentally deleted the AndroidManifest.xml from the Package Explorer panel. The file still exists intact in the original directory but I cant find any option in the Eclipse ide that seems to be for restoring it. I thought it might be 'Import' but manifest isnt one of the types on offer. Can anyone suggest how I can get the file into the package?
