cant save images on actual device but working on emulator

Hi there,

I've been able to successfully save a snapshot as a JPEG that I take from the camera to my emulator in the "data/data/com.mypackage/files/" folder by doing the following:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
FileOutputStream stream = openFileOutput( "camera_photo.jpg", MODE_WORLD_READABLE );
 
Bitmap usrPic = BitmapFactory.decodeByteArray(data, 0, data.length);
 
usrPic.compress(Bitmap.CompressFormat.JPEG, 100, stream);
 
stream.flush();
 
stream.close();
 
Parsed in 0.031 seconds,  using GeSHi 1.0.8.4

However, when I plug my actual Droid device via USB into my computer and run the application, the file supposedly is written to disk however I can't find it anywhere. I'm using ASTRO file browser app to search the entire device but I can't find it anywhere. I have set the appropriate permissions in my AndroidManifest file by way of:

Syntax: [ Download ] [ Hide ]

Using xml Syntax Highlighting

 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
 
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

so I'm not really sure what is going on. I tried writing to the SDCard also by changing the filename above to "/sdcard/camera_image.jpg" however I get an exception that says "java.lang.IllegalArgumentException: File sdcard/traffic_life.jpg contains a path separator" both when I try to run on the emulator AND my actual Droid device. Does anyone know what is going on? Ideally I'd just like to write directly to the Sdcard with a folder of my app. I'm not sure how to do this. I've searched everywhere but have found no real solutions. Any help would be greatly appreciated.

Okay so I've figured it out. In order for this now to work on my emulator I have to set the permissions of my /sdcard/ directory. Otherwise, if I want to save to my actual device I can do this:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
File f = new File(Environment.getExternalStorageDirectory() + "/camera_photo.jpg");
 
try {
 
  f.createNewFile();
 
} catch (Exception e) {
 
  e.printStackTrace();
 
  System.out.println("CAN WRITE FILE");
 
}
 
FileOutputStream stream = new FileOutputStream(f); 
 
Bitmap usrPic = BitmapFactory.decodeByteArray(data, 0, data.length);
 
usrPic.compress(Bitmap.CompressFormat.JPEG, 100, stream);
 
stream.flush();
 
stream.close();
