I am trying to create a directory hierarchy byt the mkdir returns false. What am I missing here?
File directory = _Context.getFileStreamPath("");
File subdirectory = new File(directory, "dir/mk/foo");
boolean result = subdirectory.mkdir();

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:...........................
I try to create 'foo/bar.txt' in Android's /data/data/pkg/files directory.
It seems to be a contradiction in docs:
To write to a file, call Context.openFileOutput() with the name and path.
http://developer.android.com/guide/topics/data/data-storage.html#files
The name of the file to open; can not contain path separators.

And when I call
this.openFileOutput("foo/bar.txt", Context.MODE_PRIVATE);
exception is thrown:
java.lang.IllegalArgumentException: File foo/bar.txt contains a path separator

View 1 Replies View RelatedI have a background service that plays a sound when an event has happened with the following code: 1. MediaPlayer mp = MediaPlayer.create(getBaseContext(), R.raw.theEnd); 2. mp.start(); But sometimes I see from my errorlogs that people are getting a nullpointer on line nr 2 here. My music file is a MP3 file and works great on my G1. The comments on my app says "Doesn't work on Hero after update" but I am unsure if this is specific to the Hero since I don't have that information in my errorlogs. The app has > 50000 downloads so this code works for most of the people out there, but do anyone know why it doesn't work for all of them?
View 4 Replies View Relatedmy app is working perfectly and playing its music in the 1.5 and 1.6 emulators, my ADP1, and for everyone in the Android Market (at least there were no complaints). The problem is that when the app is run on the ARCHOS 5 tabled, the MediaPlayer.create(Context context, int resid) method returns null. I guess there might be a problem with the ARCHOS' Android implementation, but did anyone experience the same problem? What might be a possible reason for the create method to return false? The docs don't say anything. I'm also using SoundPool in parallel with MediaPlayer if that's relevant.

I am new to Android and creating my first application.I want to create a file in the current directory. Basically I have a file bundled with aplication package as raw resource. I want to make a copy of this file in the current file. The reason to create copy in current directory is that I want my file reading code in native java, portable code.So my query is how can I create a file on current directory? The location current directory is important here as I do not want to make use of device specific hardcoded path or any Android API while reading the file. This is so I want my file reading code portable.

How to create a directory and sub-directory via code.
I am trying to create a folder and several subdirectory within it on the SD Card... I then want to transfer files that I have stored in /res/raw to that folder... I addition, I want this to only happen once, the first time the program is ever run. I realize that this is ridiculously open-ended, and that I am asking a lot...

The following code works when I either have no min sdk version specified in the app manifest or if it's 5 or greater. But if I set the min sdk level to 4 (Android 1.6) , it fails to create a subdirectory in the sdcard.
There is no error. mkdir() or mkdirs() just returns false.

Am I doing something wrong here? Or is this a bug? I'd prefer not to set the target to 2.1 and min version to 1.6. But right now, I have to set it to 2.0 for it to work.

I have an app that instructed me to copy some data from my computer to the SDCard. So I plugged the Droid into the computer, mounted my Droid SDCard, looked at the directory, and copied the file. There are a bunch of files and folders listed (e.g. backups for apps, album artwork, etc.) as being on the SDCard. But when I go into Astro on the Droid and select "SDCARD" it shows "directory is empty." I don't get it. Why can't I see the folders and files on the SDCard that I can see on the computer screen?
View 3 Replies View RelatedHierarchy Viewer tool is missing from my android-sdk-windows ools directory.
Link to tool: http://developer.android.com/guide/developing/tools/hierarchy-viewer.html
Should it be there is first place?
SDK Tools rev. 7, Platforms 7 & 8 packages are installed.
Is there a trick to getting the Hierarchy Viewer to work in landscape orientation, or is it completely broken? In Pixel Perfect View it shows my screen sideways (i.e. in portrait aspect ratio), but when I click on the views in the explorer area it outlines the wrong areas of the screen. It looks like the outlining assumes the display is in landscape orientation, so it outlines where the views would be if it were oriented correctly. Obviously fixing the display would be the best solution, but barring that I'm OK tilting my head if only the outlining would agree with the display. Anyone know a way around this?

If you're creating an activity, you can add add a hierarchy of views via setContent. however, if you're creating a custom component, you have to handle everything in the draw() overload.if i want to build a custom component that relies on a view hierarchy, is the model simply to create a hierarchy internally and then in draw call myViewHierarchy.Draw() or something?

I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
This all works great.
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
CODE:..........
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
CODE:................
So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.
How do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
I would be willing to bet that the vast majority of posts that are posted in the main Inc forum are for technical/troubleshooting of some sort.Or basically questions that need answers.So wouldn't it make sense to have the main forum actually be the troubleshooting forum and have the sub forum be "happy Inc thoughts.by Jack Handy"?you get the point.That's probably a lot easier on mods than constantly moving stuff.or labeling threads "moved"

Yes, this are 280 characters and Windows (7) seems to allow only 256.
Are there other methods to backup internal storage?
