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?

Is there any support for avi and other media formats except mp4 and 3gpp? If there is no support may I develop a support through correct the program? Will that be too difficult ?I don't know where to put my hands into first, should I correct programs in opencore first or should I just correct programs in directory frameworks/base/include/ media . I want to have a clear mind how I can achieve my goal, I need a roadmap to guide me how to do it.
I am trying to get familiar with the SDK 1.0 now. another question, my chip is from freescale and it supports hardware codecs of mpeg4, h.263 and h.264, I don't know whether I can change the program or the architecture of mediaplayer to utilize my hardware codecs instead of software codecs provided by android opencore. I once implement an mplayer to my platform, there is problems about sync of audio and video due to the quality of my chips(CPU can support software codecs but is not fast enough to make sure sync of audio and video), So I am worried about when the android is implemented, there would also be the same problem, and for this reason, I am thinking whether I can utilize my hardware codecs for mediaplayer.

This is 2010. I refuse to believe that you can only play movies/video files that have .avi, .mp4, .mpg, .mkv file formats by converting. I remember Sony was slow on the uptake when they started the media server streaming which I use on a daily basis at home now.Is there a program that will decode the files as you stream them? Any codecs to install on the Droid X? I have thousands of video files and "converting" is time consuming not to mention creating two video files instead of one to play on devices. Converting is BS and whoever thought "Let's just have the users convert the video files" needs to take a long walk off a short pier.

Let me start by saying that I absolutely love the Captivate- it's my first Android phone- been using Symbian phones for 6 years and have had an ipod touch for all the apps. I'm used to good headphones- having owned upper level Sonys and Ultimate Ears. The set that comes with Captivate is fairly mid grade- not awful, but not great either. I've been looking at aftermarket headsets with microphone and there are very few models advertised as compatible with Android phones, but tons of choices for iPhone.I see that many posters here own(ed) iPhones.Do the iPhone headset with microphone work with Captivate as expected? Are there possibly mic sensitivity issues, or some other things I should look out for? Looking to get a set in the $70-$120 range so that I can enjoy my mostly lossless music library.

Have already posted this in "multimedia". Sorry for reposting, but I hadn't seen this group before. Q1: On youtube and other websites I, more often than not, get the message "Cannot play this file". I suppose the reason is that the file format is not supported? Can I download a codecs pack somewhere in order to get more out of my phone? Q2: Is there a flash plugin for the Android browser or an alternative browser available, and where do I get it?

I've got a custom xml file in my res/xml folder, and it's not an android xml file (in that it doesn't describe a button or set of views or anything, just data for my app) and now I want to read it with an XML Pull Parser, but I don't know where to find it on the android file system. I've googled a little bit and I cannot come up with a document that shows what the android file system even is. (I'm sure it's out there). Can anyone tell me how to find the xml file? or point me to a doc that tells me how to do the same?

Does anyone know of a quick color picker widget that I could grab to use in my application? I've seen one in a few different applications that has a wheel with colors, and that you tap in the center to select, but I'm not sure where to find it. Google brings up nothing. Any color picker would be fine though.

I have a WebView on my Android application which loads (WebView.loadUrl()) different local HTML files from phone's internal storage. I would like to include some custom css styles for them, Now, I could have my app edit every HTML file and add linking reference for the CSS file.I could also read the file contents, add the CSS linking and use WebView.loadData() to load it.But is it possible to do this a lot simpler and efficiently.Note: The HTML files are downloaded from a website. So editing them manually is not possible in this case, but once downloaded they can be edited via the app if necessary.

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 have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded.
UPDATE - I just had one idea it will work sort of but has problem if the DownloadRunnable gets changed between executions of the downloads.
The modified Runnable interface
interface DownloadRunnable {
void run(InputStream stream);
}
An enum
public enum ServiceHandler {.......................

I've followed the steps given in the Android Developer Blog to generate a build.xml for building releases for an Android Application. I need to do a custom compiling so I have overwritten the target compile of the ant_rules_r3.xml as it is said in the generated build.xml.
<target name="compile" depends="-resource-src, -aidl, -pre-compile" ...
The script works fine and generates the apk, but the problem is that Eclipse shows an error because it cannot find targets -resource-src, -aidl and -pre-compile (which are loaded when executing the script but are not really present on the build.xml). As there are these errors I cannot work with the project in Eclipse.
How can I skip the validation of this single file in Eclipse?

I'm able to successfully use a ScrollView inside the layout xml file for an application. However, when I tried using a ScrollView inside the layout xml file for a widget, I get a "Problem Loading Widget" error as soon as I drop the widget in the emulator. If I comment out the ScrollView, then the widget shows up in the emulator. I've pasted my layout xml file below. Any thoughts on how to get past this error would be much appreciated.
