Android :: Does The Dalvik File Format - .dx - Support More Instructions Than Java .class File

Apr 17, 2010

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?

Android :: Is It Efficient To Use Text File Or XML File To Store Static Data

Jul 31, 2009

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".

Android :: Resize Large Bitmap File To Scaled Output File

Jul 26, 2010

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.

Android : Is There A File Picker Widget For Custom File Formats

Oct 27, 2010

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?

Let's say you have an apk file on your SD card. How would you install the apk file? Terminal emulator, using which commands or another way?

By the way, ASTRO File Manager vs. ES File Explorer, which one and why?

General :: No File Extension Association - Unknown MIME Type File

Apr 3, 2013

I'm using JB 1.4.2 on Razr i. There's one thing that's annoying me a lot. I've installed the SNES Emulator SuperGNES and I've found that every single file type that have no app associated is showing SuperGNES icon and associated with it. Example: .log, .db, etc. Even files that have no extension is associated with it. The same problem occur when ZArchiver is installed. I don't know if it's a bug of these two apps or Android's in general. Remembering that this associations are shown only inside Android's native file manager. It's like every "unknown MIME type file" act like being the same.

Android :: User Preferences File Vs App Preferences File

2) I'd like to define another file for global configuration preferences of my app.

What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?

Android :: PendingIntent Always Creates New Activity Instance?

May 21, 2010

My app consists of an Activity and a service that runs in the background. The service periodically checks a website for an alarm condition. When the service detects the alarm, it should put a user notification into the status bar. If the user clicks the notification, it should display the app's activity. If the activity is already running, that activity should become visible. If the activity is not currently running, it should be created.

However the notification created by my service *always* creates a new instance of the activity, whether the activity is currently running or not. How do I get the desirable behavior?

Here is my service pseudo-code:
