Best Format For Showing Latex Files?
May 27, 2012
I'm developing an application that is going to essentially list and show a bunch of pictures (one view, one picture) with text and tables.As of now the resources that we are going to show are in latex format. What format makes the least hassle to convert the latex to and show in android if we want it to work for versions 2.2+?
Normal bitmat images would be easiest I think, but my client want's vector-based format for maximum quality.
I just want to show the images not manipulate them. Should I try PDF, or SVG? I was also thinking about HTML, or what lib is recommended for that format?

I have an application which we are writing to be both a MIDP application using LWUIT as well as an Android application.
We attempt to share as much common code as possible between the two platforms.
I'd also really like to be able to share the localization strings when possible.
Reading through the docs in:
http://developer.android.com/guide/topics/resources/resources-i18n.html
It looks like Android uses an XML format to specify name-value pairs, e.g.:
{{{ <string name="go_online_message">You are currently offline. Go online? This will use the data network</string> }}}

I put in a 32GB sd card. I formatted it (FAT 32) and simply copied the files from my original that came with the phone. I had over 1500 music files, but while they are on the 32 GB card, only 100 are showing up in the music player. I deleted everything and recopied the original card

I had a bunch of non-DRM music that I tranfered from my mac iTunes account over to my EVO's memory card. The files play fine, but none of them show the album art anymore (it is just a blank CD image with a little android up top). All of the data should be there as it plays just fine in iTunes and didn't have issues on the iPhone. Is there any way I can get the album art back?

So I have about 1,000 songs on my phone and earlier today I connected my phone to my computer so I can add more music. When I opened my music folder on my phone, it stopped at 349 songs and the rest of them showed up as a "hard drive" icon? What happened? When I disconnect my phone to see if my music was deleted or something, it wasn't. It's still there on my phone but just won't show up on my computer.

I just had a warranty swap out done on my droid. As soon as I got the new droid, I hooked it up to my computer flashed back to Android 2.0.1, and used Universal AndRoot to root the phone. After that I used Rom Manager to flash ClockworkMod, and then I installed a backup that I did on my previous Droid. Everything workd great. I'm back running CM 6.0 set up just as it was on my old phone.
The problem now is that when I go into settings to change a ring tone or a notification tone all the "stock" sounds are listed twice. I don't know how to remove the duplicate.
I've deleted system/media/audio, rebooted the phone and then I only had one of everything in the menus to choose a tone. This had a negative effect as it also deleted sounds for some other actions as well. So I moved a backup copy of audio back to system/media, and the duplicates are back.
I've searched with Root Explorer for various ringtone files, and have deleted files off my SDcard thinking it was pulling files from it, but that hasn't worked.

I installed a game from gameloft (Let's golf, great graphics btw)
Anyway I notice a bunch of sounds files were showing up in my music player I didn't want. Very annoying. I searched around here and didn't really find that much help. After some further searching around the net the easiest way I could find was as follows:
1. Open up notepad, don't type anything just go to file, save as. Change the drop down box for Save as type: select all files. Under file name simply type ".nomedia" without quotes.
2. Connect your phone to your computer, locate where the sound files you don't want are. In the same folder as where all the files are, drag the .nomedia file you made to that folder. Disconnect the phone
3. Reboot your phone, once booted open up the music player (you might still see the files there since it's cached) Go to the all songs tab, select a song. This will refresh the cache and you should no longer see any annoying files in your widget or playlist.
Before this I had to make a custom playlist and select that but everytime I rebooted I would have to select the playlist again plus if you add new songs you would have to go into the playlist.
Also if you don't know where the annoying files are, you should be able to hold down on it in the music application and go to details. This will show u where the files are located.

I have loaded about 538 mp3 music files on the SD card in my Droid Eris. Only 50 were listed in the Music player. I deleted the files and copied them again to the card. Now, only 186 are listed in the Music player. Am I missing a step or is the software screwed-up?

I've recently bought a SanDisk 4GB SD Card, format it to NTFS, I was able to copy large files like my Need For Speed SD Data, .apk files. Then I've checked it in my phone if it is success. But for some reason, .apk files were not showing up on the list, all I see is the SD Data of my NFS.

I downloaded a picture from the web onto my X. I used dropbox. The problem I'm having is I can see the picture when I go to phone files. I copy and paste from dropbox to my picture folder. The picture doesn't show up in the gallery. So just to be sure I copied the picture to a folder called background, its still not there in the gallery. Weird thing is when I go back to the phone files, and look for it. Its there in the gallery folder AND the background folder, but STILL not in the gallery! not sure whats going on there? I just want to make a picture a background thats all. It would be nice to just go into the phone files LONG press a picture and have the "Set As" option. This option only seems to be available in the gallery.

I find it kinda annoying that recordings made the voice recorder application show up in the music player. I'd like to have only my music play when I set it to shuffle. I have all my music in a folder called music. Can I limit the music player to search in that folder only?

I recently installed Asphalt 5. Apparently, you have to download some stuff in order to play the game. Anyways, I did download it and my problem is, there are sound files that are showing up on my music player. Ex: (raw_000~raw_174) Oh and the sound files are in ".ogg" format. I did some research and I tried the ".nomedia" method, but that didn't work.

How do you block Android game files from adding themselves to your media players? For example, if you're using Moboplayer to view the pics and vids you've shot with your camera, and you have a game like Dragon's Lair that has hundreds of mini 3 mB vid clips on your device to play the game, when I try to view my personal videos, I have to filter through the 800 some odd game vid clips just to look at my home videos. To add insult to injury, if you use a backup like Verizon that backs up only your newest movies and pics, it also downloads these hundreds of vid clips as well as photos of the uniforms on a game like Home Run Battle.

Is there a way to determine the audio format of an audio file in Android? On normal java I do it like this:
File file= new File(...);
AudioInputStream stream = AudioSystem.getAudioInputStream(file);
AudioFormat format= stream.getFormat();

Passing two int values m =0 & s = 11, to below function String formatted = String.format("%1$02d:%2$02d", m, s); returning the value like .0:11 ,What could be the problem? m=0, s=11 -->.0:11 m=0, s=1 --> .0:.1. The 0 added to format the string always coming as '.' (dot). Can anyone know ,from where the number patterns are getting loaded in Android? I gone thorough the code, Its related the following file, androiddalviklibcoreicusrcmainjavacomibmicu4jniutil Resources.java ->localeData.numberPattern. How the pattern for particular locale is loaded, What could be the problem for the above?

I have a Samsung Galaxy I7500 using android 1.5. I extended my phone with a 16GB microSD. I copied a big music collection (around 800 files) into a folder on this SD. Now the problem is that the music player can't find all the files.
I know that there are several threads about android not finding music. The answers are usually that the library hasn't yet been updated or that the ID3 tags are not correct.
I have checked both.
Btw. I can play the files using ASTRO.
In my opinion it seems as if android can't build up a library with too many entries. If I rename the files or put them into different folders, songs disappear and reappear quite randomly.
Do you have any solutions? Is there a music player which doesn't use the native music players index of files?

Can anybody advice what is the recommended directory to store files generated by your application: audio files, video files or some images.
If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?

I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.
Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/W
Last login: Wed Mar 18 19:41:49 on ttys005 localhost:~ mkamp$ adb -d shell rm /sdcard/newsrob/a* [.. minutes of silent deletes ..] rm failed for /sdcard/newsrob/a2aade03616c28b30_113.png, Read-only file system localhost:~ mkamp$
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat ro,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/O now
The log contained nothing but the usual gc output and random WiFi status changed mumbo jumbo.
Anybody else seeing this behavior?
There were 6.500 files in that directory. Might that be the problem? I don't access the files with queries, I always have the exact name.

I am working on an android app. Where i need to parse some plist files from assets folder. I do understand how to use assets in android but now problem is that file sizes are more than 1MB and so android gives error Data Exceeds UNCOMPRESS_DATA_MAX (2183588 vs 1048576). how to access such larger files from assets? Also I cant reduce a file into small buffers because i am just sending it to "DocumentBuilder.parse(in)" as a whole so can not use buffer. The error is on line: Document doc = db.parse(in).

I uploaded about 50 pictures from iPhoto (using a Mac) just to see what they looked like and then later formatted the Droid's SD card, so the pictures were no longer there.
Now, if I mount the Droid via USB and view the file structure there is a folder named /albumthumbs which contains 50 files, presumably for the 50 pictures a had on the SD card.
To me, these file, unless linking to actual photos stored on the SD card, take up extra space in the phone's memory (not worried about the SD card). I wonder if I can safely delete them (just the files...not the folder)?
