Hello there I was wondering if someone may be able to help me...
I have a Live Wallpaper app that is working very well on Eclair but
there is a strange issue with Froyo that I can't find any information
about. The user is able to select a custom picture as a background
from their gallery and it will be saved to internal storage (/
Snowflakes/CustomBG.jpg) and applied as a background to the live
wallpaper. That all works fine until the user reboots their phone...
The problem is that the internal storage doesn't seem to be mounted in
time for when the live wallpaper starts and so it reverts to the
default setting when null is returned (see code below). As I say,
this problem has only been introduced with Froyo as Eclair works fine
(the image is found and used so the internal storage must be mounted
before the Live Wallpaper starts). Here's the code that searches for
the CustomBG.jpg image on startup...
@Override
public void onSurfaceCreated(SurfaceHolder holder) {
super.onSurfaceCreated(holder);
c = holder.lockCanvas();
canvasSize = new Point(c.getWidth(), c.getHeight());
globalCanvasSize = canvasSize;
holder.unlockCanvasAndPost(c);
generateBackgroundGraphic();
}
private void generateBackgroundGraphic() {
if (backgroundToJPG() == null) { //default to gradient
pattern
background = BitmapFactory.decodeResource(res,
R.raw.gradient);
Log.d("pic", "(SF) File doesn't exist to using Gradient
as
default");
} else {
background =
BitmapFactory.decodeFile(backgroundToJPG().getPath());
Log.d("pic", "(SF) File does exist so using
'/Snowflakes/
CustomBG.jpg' as background");
}
}
private File backgroundToJPG() {
String status = Environment.getExternalStorageState();
if (status.equals(Environment.MEDIA_MOUNTED)) {
File d = new
File(Environment.getExternalStorageDirectory()
+"/Snowflakes");
d.mkdirs();
File f = new File(d,"CustomBG.jpg");
if (!f.exists()) {return null;}
return f; // <-- FILE
NOT
BEING RETURNED HERE!!
}
}
Apologies for the code formatting - is there any way I can improve
this? Anyway, I'd be very grateful for any help you may have... I
can't find any information about this on-line so perhaps there's
something wrong with my code?
Thanks, Chris
