Android :: 2.2 - SD Card File Directory List Now In Reverse Alphabetical Order?
Jul 24, 2010
I don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):
CODE:.........
The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.
In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.

I'm new in Java/Android programming, so please have patience with me.
I try to play a mp3 which is locate und the assets folder. I know there is another way with the /res/raw/ folder, but use the assets-folder because later I'll try to access the file by String.
This code works to play a mp3-file:
CODE:...............
Now the problem: In the same assets-folder is another mp3 file stored. Though I specify the name of the mp3 to use it take the one which comes first in alphabet. E.g. the other file is named "music.mp3" it plays this one. Renaming it to "worldmusic.mp3" it will play "song.mp3". Rerename "worldmusic.mp3" back to "music.mp3" it will take this mp3 again. Another test: Renaming "song.mp3" to something other so the application can find whats specify by the code above will result that no song is played. So this means the songname have to exist, although it take arbitrary the song first in alphabet.
I'm testing with the AVD emulator of eclipse. But I think the behaviour would be the same on a real device.

I'm happy reading and writing to a pre-set file, and could manually populate a listview, but I'm hoping there is an official(or not) filebrowser I missed, or other more elegant solution to present the user with a directory listing, and let them select a file.

Using code from open source MusicDroid with the following code that I found during a search for this problem, I can only get mp3 files that are in the root directory /sdcard/
CODE:........
How can I get all the mp3 files from the card (in any directory) into my 'songs' list?

Is there any way out there to organize your apps menu other than by alphabetical order? When you have a heaps of different apps and are always trying new ones like me it's not always easy to find that one that has a name that relates nothing to its function.Ideally I'd like some way of making categories in my app menu and and grouping all my utility icons, all my game icons etc.

I know it's a small issue for most, but it's just really annoying that the settings menu can't be alphabetized. Or if it can, can someone tell me how to do it?

I'm using the stock bookmark widget. Is there any way to set it up in alphabetical order on the widget? I can set it to show me my bookmarks in alphabetical order each time I start the browser, but it reverts back to the order I saved them in on the widget.

I am configuring a tablet for my grandparents, and I am struggling to find an Android keyboard which arrange keys in alphabetical order (A B C D ...) instead of QWERTY.
I am not looking for a keyboard with combined keys using dictionaries like dialpad/T9 (which would be too complicated for them), I just need a basic keyboard with one virtual key per letter.
I thought that this would be very common and easy to find, but it's not The only applications that I found are :
Keyboard for Senior Citizens : would be perfect but does not scale up correctly on tablet.
Keyboard for Dyslexics (lol) : seems to be exactly the same as the "senior" version, did not try because it s an other pay app and has same developer, screenshots and description.
Kids Keyboard : Scale problem in landscape on tablet : too small.
Alphabetical Keyboard : takes the whole screen in landscape on tablet.
Simple Large Button Keyboard : Scale problem in landscape on tablet : too small.
SlideIT English - ABC pack : layout addon for SlideIT keyboard, but I don't like the suggestion panel remaining on the top.
Dextr Alphabetic Keyboard : the only functional from the list, but I would rather use a design closer to a traditional keyboard.
If any better keyboard with ABCD order or a keyboard which would let me customize the layout, I would be very interested.

Is there a way to re-arrange the applications list in grid view in alphabetical order?
If I switch to "list view", they are in alphabetical order, but in grid view, they are not. I could not find a way to do it.

Does anyone else have problems with the music player ordering your songs in alphabetical order instead of in the order they appear on the original album? I've never had this problem with iTunes or iPhone, but with Droid X, all of my MP3 albums are ordered in this way. (FYI, the issue is the same if it's an actual MP3 or AAC format.)

I´m doing a layout animation on my listview where I fade the list elements into view using a LayoutAnimation with android:animationOrder="normal". It works perfectly fine and the elements are faded into view in top-to-bottom order. However, if I trigger a layout animation twice (eg call startLayoutAnimation before the list view has finished animating its views), the listview performs the new layout animation in reverse order; bottom-to-top.

Does anyone know how to fix the default Music player's behaviour when long-pressing on an album and selecting "Play" ?
If you start playing by quick-pressing the album, it shows you the list of songs. If tagged correctly, this list is in correct song order, and will play the album in order from whichever song you select to start from. If not tagged correctly, it shows in alphabetical order.
So far, so good.. can't complain... BUT...
If you start playing an album by long-pressing it and selecting "Play", it plays it alphabetically, regardless of the status of the tagging.

Do anyone have a file in the root directory of your SD card named search.trace? I have one that is about 8.5 megs. I took a look at it but it didn't look like the entries were specific to a particular app. Looks like some system log. Anyone know if there would be a problem deleting it?

At some points while running my android application, I need to create a directory on the sd card, for a small number of users this fails and I can't figure out the reason for it... (I've found similar problems caused by the WRITE_EXTERNAL_STORAGE permission missing, it's there and it works for almost all users so I don't think this is reason) When mkdirs returns false I crash the program and log the following java.io.File properties, starting at the directory I want to create, then recursive printing properties of the parent directory and so on...
/sdcard/MyDirectory/Dir1/Dir2 (exists: false, canWrite: false, isDirectory: false, isFile: false);
/sdcard/MyDirectory/Dir1 (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard/MyDirectory (exists: true, canWrite: true, isDirectory: true, isFile: false);
/sdcard (exists: true, canWrite: true, isDirectory: true, isFile: false);
/ (exists: true, canWrite: false, isDirectory: true, isFile: false);
The strange thing is that the parent directory is writable (canWrite=true), I can't print the execute file permission but from what I've read, write is what you need when creating directories... What I've looked at so far is the WRITE_EXTERNAL_STORAGE permission, if the sd card is full and if the sdcard is mounted read only:...........................

When making an image I accidentally had Clockworkmod image be saved to the device itself instead of being saved to the external SD card.
I am able to browse to it using Root Explorer and select to Copy it, but how do I PASTE it onto the external SD card when Root Explorer only accesses the device directory and not the external SD card?
Quick 2nd question: I know on some previous devices such as the Galaxy S 4G you were *not* supposed to run Clockworkmod after booting in and from the Apps Drawer, instead you were only supposed to run directly from the startup screen before booting in. Is it OK to actually start the Clockwork Backup/Restore process from the Apps Drawer of the Galaxy S4 and let it reboot and do its thing or is it only supposed to be run BEFORE booting in?

Coming from a Iphone to the X the music player is a little lacking. Often I will go into a certain artist and want to play all the songs by that artist, or thumb through all their songs to find a certain one. On the stock music player on the X this seems hard to do (maybe I'm missing something).
if I pull up the music by artist and select a certain artist then it shows me all their albums (The iphone has the option at this point to select all albums and see all the songs of that artist in alphabetical order). The X doesn't give a option to select all albums at this point. If I go to artists and long press on a certain artist I can select play and it will start playing all that artists songs, then I can hit pause and go into the list from that point to see all the songs but they seem to be in a random order making it hard to find a specific song.
I've tried a couple other players and haven't been able to find one that functions like the Iphone, makes it hard to quickly find one song.

Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

I was wondering how safe it is for my apk to be uploaded without being obfuscated. I am kindof in a hurry to upload it on the market and I was thinking of uploading it unobfuscated. I am guessing this is probably how most of the apps are uploaded anyway but I would like to hear people's opinions on this. I haven't searched online for existence of tools that reverse engineer the .dex file the android project creates.

I need to create a list view that display same functionality as Contact App. I need to have a scroller through which i can traverse the list alphabetically. To achieve this i am following an example from API demos "com.example.android.apis.view.List1.java". It is using a textfilter. When i implement this functionality on a static list view => it is working fine. But when i try this on a dynamic listview=> it is not working.

I want to build a list that show the directory tree like list similar to folders view on the left pane in 'Windows Explorer'. I have seen ExpandableList but this goes into 2 levels only. I want to go into multiple levels. Expand the item by clicking on the left icon and show sub directories in it. Click on sub directory expand icon, show the sub-sub diretories in it and so on.

I am new to android, and ended up (have to) ask a question here, Let's make it simple, I simply want to make my own TextView-like (MyView extends View). This is my code:
public class MyView extends View { private Paint mPaint; private String mText;
private Bitmap mBitmap1; private Bitmap mBitmap2; public MyView(Context context) {
super(context); initView(); } public MyView(Context context, AttributeSet attrs) {
super(context, attrs); initView(); } private final void initView() {
mPaint = new Paint(); } public void setText(String text) { mText = text;
} @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int measuredWidth = measureWidth(widthMeasureSpec);
if (mBitmap1 == null) initBitmap1(measuredWidth);
int measuredHeight = measureHeight(heightMeasureSpec);
setMeasuredDimension(measuredWidth, measuredHeight);
} private void initBitmap1(int measuredWidth) {
mBitmap1 = Bitmap.createBitmap(measuredWidth, Fonts.getHeight(), Bitmap.Config.ARGB_4444);
Canvas canvas = new Canvas(mBitmap1 ); canvas.drawText(mText, 0, 0, mPaint);
} private void initBitmap2() { mBitmap2 = Bitmap.createBitmap(30,
Fonts.getHeight(), Bitmap.Config.ARGB_4444); Canvas canvas = new Canvas(mBitmap2;
canvas.drawText(mText, 0, 0, mPaint);}
private int measureWidth(int widthMeasureSpec) { int measuredWidth = 0;
int specWidthMode = MeasureSpec.getMode(widthMeasureSpec);
int specWidthSize = MeasureSpec.getSize(widthMeasureSpec);
if (specWidthMode == MeasureSpec.EXACTLY) { measuredWidth = specWidthSize;

measuredWidth = Math.min(measuredWidth, specWidthSize);
} } return measuredWidth; }

@Override protected void onDraw(Canvas canvas) {

initBitmap2(); canvas.drawBitmap(mBitmap2, getLeft(), 30, mPaint); } }

MODE_ WORLD_ WRITABLE ) ; openFileOutput failed, because fIle "/sdcard/xxx.txt" contains a path seperator. It is so strange. Is there another way to handle the situation?

I'm trying to save a file in a subdirectory in Android 1.5.I get a exception saying I can't have directory separator in a file name ("/"). I'm missing something of working with files in Android..I thought I could use the standard Java classes but they don't seem to work.I searched the Android documentation but I couldn't fine example and google is not helping me too.I'm asking the wrong question (to google).

initBitmap2(); canvas.drawBitmap(mBitmap2, getLeft(), 30, mPaint);
} }
In my code, I populate some numbers of MyView (let's say 20) in a ListActivity. My question is why mBitmap1's order changes randomly while i scroll (up-down) fastly (if I scroll slowly, this problem not occur)? mBitmap2 stays where those should be.
