CODE:.............
I'm currently using the above code to create a folder which is used to temporarily store images that the app uses later. deleteDir is just a generic recursive file deletion to empty a directory. Is there a better way to do this than to delete everything? Ideally I just want a temp folder that empties when the application closes.

I want to buy a couple of android devices for use by our sales representatives. However I want to put some files (powerpoint presentation, pdf or photos) on those devices which I want to lock against deletion by a user.
Is there a software to achive it?
Protection can be secured with a password, pin or whatever.
I tried to find such a program but no luck.
When using
file.createNewFile();
I get the following exception
java.io.IOException: Parent directory of file does not exist: /.../pkg/databases/mydb
I am wondering is there a createNewFile that creates the missing parent directories?
Are there any temp, volatile directories in the Android file system that get wiped once the device is off? In Linux we have /tmp, but this doesn't seem to exist in Android.

Now a strange thing is occurring. I installed an off market app, but I can only see its folder in Android's File Manager, not in Windows XP.
This is going to cause me serious problems because I need to transfer some files into that folder from my PC.
How can I access this App's folder in Win XP?
i am currently making an application in which i require to delete an sms. How do i go about it. Also I may need to hide a sms i.e not visible in the inbox but i may choose to unhide it later.
View 2 Replies View RelatedI have problem with deletion sms with messageId=0. I can't delete such a message. There is no problem with deletion other messages but first message taken from inbox has always message Id=0 and I can't delete it. I use code below for deletion.
Uri SMS_CONTENT_URI = Uri.parse("content://sms"); Uri deleteUri = Uri.withAppendedPath(SMS_CONTENT_URI, String.valueOf(smsList.get(currentSmsIndex).getId())); int count = context.getContentResolver().delete(deleteUri, null, null);
Do you have any idea?
I want to force the User Data to be deleted on Application upgrade (to delete internal database).How can I do that?
View 5 Replies View RelatedI notice that my app's data on external storage (i.e. SD card) gets deleted during an "adb install -r". While this is normal for uninstall (and then afterwards install optionally to notice it), I do not understand why this is the case for reinstall (and thus for Market updates as well). I could have sworn this was not always the case.
Referring to http://developer.android.com/guide/topics/data/data-storage.html#filesExternal I am specifically using "Accessing files on external storage" on Android 2.2, but not "Saving files that should be shared" or "Saving cache files". So I am writing and reading data in "/sdcard/Android/data//files/somefolder/data". My preferences do stick.
@Commonsware: The problem is not so much with getExternalFilesDir() IMHO as I see my data is written where I expect it. It just does not stick. I am using a.o.:
public static File getDefaultDirectory(Context context, String packageName) { File dir;
if(mActivity_getExternalFilesDir!=null){//API >=8
dir = invokeGetExternalFilesDir(context, "fortune");
}else if(mEnvironment_getExternalStorageDirectory!=null){//API <=7
dir = invokeGetExternalStorageDirectory();
dir = new File(dir.getPath() + "/Android/data/" + packageName + "/files/");
}else{ //should never occur return null;
}return dir;
}
I did some searching around but couldn't find any answers; my question is how do you delete the restoration images so you can keep only two or if you find you don't need some of the older ones etc...

One of the biggest features that I found missing in Android was the ability to delete mail on handheld only, or handheld and server on a per message basis. (For those not aware, you can set BB to do either automatically, or prompt, which is what I like.)

View 6 Replies View RelatedI have a thread with over 1200 text messages in it which I need to delete to improve the lag on my phone. However there are a few of the messages which I would like to keep. I am using the stock message app. When I long press to delete the thread there is an option you can check to delete locked messages, however no where can I find the ability to lock a message. Does anyone know how to lock a message within a thread so you can delete the thread but keep just a few of the messages?

View 3 Replies View RelatedIs it possible to create files in subdirectories created under "/data/data/packagename/files/" directory using openFileOutput method in android?
ie there is a sub-directory by name "text" inside the "/data/data/packagename/files/" directory.
I want to use the openFileOutput (String name, int mode) method to write a file eg:sample.txt into this directory....Is it possible to use openFileOutput method to do it....
I see that as of API Level 8, you can request a handle to special directories with Environment.getExternalStoragePublicDirectory. This takes a type such as DIRECTORY_MUSIC, DIRECTORY_PICTURES, etc.
I'm looking for an equivalent directory for other media types such as documents (Word docs, PDFs, etc.). My HTC Desire has a "/sdcard/My Documents/" folder which looks like exactly what I want, but it has no DIRECTORY_ specifier for use with the above method. Is this a standard Android directory which I can rely on?
If I can't use getExternalStoragePublicDirectory, I have to use getExternalStorageDirectory instead which just points me to the root of the SD card. I can explicitly check for the presence of "My Documents" under the root and use it if it's there.
This is what I have:

Is there a better way?

Is there a program for the Android OS that allows to to access your files and directories, like 'Windows Explorer' does on your desktop pc? I have some audio files that I would like to move to the ringtone directory.
View 4 Replies View RelatedI have images uploaded on the simulated sdcard on my emulator. I downloaded them from the browser, using the long-click on each image.
When I look at the file explorer in the DDMS perspective, I see that they are in the directory sdcard/download.
Now if I want to download some audio files and use them in an app to, say list the title of all audio files, will they go in the same directory? (I am trying to push the audio files manually from my computer to the emulator).
This doesn't seem right. Shouldn't the media files of different types (pictures, audio, video) go into different directories?
Also, thinking this through a little, how is something like this related to the physical directory on the sdcard?
Uri mMedia = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
If I upgrade my SD card from say 8 to 16 gigs... can I merely copy over the directories from my old card to my new one so that my apps still work the same? Are there any hidden files or directories I need to worry about?

It seems as if Eclipse is trying to build the files in the .svn directories now. This setup used to work fine.
I've experienced a strange issue running applications on the HTC Desire.
When I call getApplicationContext().getCacheDir() or getApplicationContext().getFilesDir() from my activity this always returns null. In the emulator /data/data/com.myapp.android/cache respectively /data/data/com.myapp.android/files is returned.
Because of that I'm not able to use the webview class as it tries to create cache files and crashes with a null pointer exception. The logs:

I noticed that other apps have issues as well. For example the google finance app logs the following message:

Why I cannot create folders in this directory?
Is there a possibility to set the fileDir and cacheDir paths to the sd card or somewhere else? I looked at some classes like Context, Webview and CacheManager but I could not find a way to change it.
Do I need to set a permission to create cache files?
Is there a way to make apps not store settings in the SDcard or to have them all in a specific folder my card is looking kinda messy.

View 2 Replies View RelatedOn my HTC-03A, it has Android 1.6. I can't upgrade because Docomo won't let me.
Anyway, I thought the version would be relevant to my question.
It's a small issue, but in the default music player, when I look at the library, there are directories and play lists there which I have long since removed from the SD card. I also have 3 different play lists titled "podcasts", and I don't know how that happened.
I thought it might be the default music player at fault, so I downloaded Mixzing, but it showed the exact same playlists, empty and deleted ones and all.
So something on my Android is hanging on to old information somewhere.
Any idea where and how I can edit it so that I can clean up my play lists?
