I have a string called extStorageDirectory which is set to my SD Card and then "/mypics", I can then save a picture in to this directory, but only if the directory exsists. So how do I check to see if the directory exsits, and if it doesn't creates the directory?

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 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?

Currently, to initialize data for the first time (not repeatedly), we try of open the db and if it fails we know the database does not exists otherwise it is already created and initialized.
Is there any simple API available to check whether DB exists or not ?
I am working on a simple app for the HTC EVO that blinks the alternate notification LED when a new text message is received. I have this part working great via a Broadcast Receiver but I need some way to turn the LED off when the user has read the message(s) using their default SMS app. I'm not sure if it is best to do this in the receiver or in a background service.

View 4 Replies View RelatedIs there a way to programmatically without root check and see how a program was installed?
The only solution I've been able to find is using root - and tapping into a database that the Vending application uses;
CREATE TABLE assets10(_id INTEGER PRIMARY KEY AUTOINCREMENT, content_uri TEXT, s tate TEXT, download_pending_time INTEGER, download_start_time INTEGER, install_t ime INTEGER, uninstall_time INTEGER, size INTEGER, type TEXT, package_name TEXT, is_forward_locked TEXT, signature TEXT, refund_timeout INTEGER, version_code IN TEGER, server_string_id TEXT UNIQUE);
Most specifically I can check to this database using my package name and/or signature and see if it's ever been installed by the market. Then if it has you could check to see if it's been uninstalled.
As for background, I'm just messing around with ways to distinguish real users from pirated versions. I've noticed from an application I've posted that I only have approximately 100 downloads and 50% active, yet my server which is used by the application shows approximately 200ish unique users within the past few days.
I am doing an experimental project and want to send key events from one application to another. I know android doesn't allow applications to interfere each other in this way due to security concern. Is there any way i could bypass the security check? I've looked into the WindowManagerService class and made some modifications but it seems not working for me.

Clearly this code is not sufficient (perhaps it would only return true if I sent some bit over the network and turned the radio on?). Moreover, since I'm not well versed in the ConnectivityManager, I'm assuming I should probably be scanning all networks (ie: getNetworkInfo(0 through N)).

Since I got my 16 GB Card it's started saying it for longer than with my 2GB Card, however it says it less now. Does how long it takes depend on how much data you put on since taking it out of USB Mode? Because when I first got this card I wrote a lot to it (Moving all my files over), but now I just put a few files here and there on... Is there a way to disable this and let you run it manually at your leisure?
View 2 Replies View RelatedI have a terrible bug in my widget. The widget is waken up using an AlarmManager (the update interval is chosen by users, ranging from 30 mins to 2 hours) to grab some data from the Internet and display it on the widget. I do not hold a wakelock since if the phone sleeps, just let it sleeps. There's no way to update the information since nobody will see it. If I put the phone in the basement (has no wi-fi or cell signal) for about an hour. the phone will definitely not update anything. However, when I get it back from the basement, the cell network could never be recovered again no matter how long I have waited (it just get an X on the cell signal icon on the notification bar) that I must restart the phone. May I know if a partial wake lock must be held on checking network availability?

I got problem with register. I use an if-else statement to check whether the user left any blank. If there is any blank, an error message will appear. The problem is, even with no blanks, all filled up, the error message still appears and thus prevents user from registering. I can't find any error.

I'm writing a game for Android. I'd like to target as many devices as possible. I'm aware that Droid owners buy about 50% of the apps and the rest are a mixture of G1 and HTC devices. So far, I've been testing my app in the emulator set to model the Droid phone (where I get about 40 fps) as well as on an actual Droid phone (where I get about 60 fps).
I'd like to know how fast my app runs on slower devices such as the G1. Is there any way I can do this besides getting a G1 myself or asking people with G1s to test it for me? For example, is there any way I can use the emulator to get a rough idea how well it will run on the G1?
After you give an app permission to auto-update, does anyone know how often it checks for a new version of itself? Does the app check daily and if an update is found (and provided it does not alter the permissions) apply it? Is it possible to alter the frequency that it checks?
I ask because I just opened up the Android Market and right as I did so it suddenly started updating half a dozen apps. Now that was fine, since they all had been given permission to auto-update, but I want to know if they only check for an update when the market is opened, or if it was just a coincidence.
I am writing a screen scraping app that reads out various pages and extracts the data. I'm using the SAXParserFactory go get a SAXParser which in turn gets me an XMLReader. I have configured the Factory like this. code...

EDIT: This is for an Android app, which is why I am reluctant to use an API/library that isn't in the standard environment.
So I have everything set up to automatically use my Google Voice number now, and started getting SMS texts in both my messaging inbox and in GV. I figured out I needed to turn off the SMS forwarding in GV, but it turns out I like using the default messaging app more than the one in GV.
Is there a way to make the GV app stop checking for SMS messages but still download my voicemail? I don't want to make it stop checking all together but I'd like to use the other app for SMS's.
I had to turn off auto correction and word prediction. I need a way to optionally spell check text after I've finished typing in a text field. Is there a way out of the box to do that? Do I need an additional application? If so, what's the best one?

I installed the Missed Reminder app on my phone this weekend but I've read around here that this is a big battery drain program. By navigating to the Battery usage section within the Android settings, the Missed Reminder app doesn't even show up. Does this mean the app is NOT draining, or am I looking in the wrong area?
