Easy i was playing with a little app i'm developing but i've just
found a little problem... let's explain me it...
I created a sdcard and inside it I placed some jpg files.
So my data path is something like:
/sdcard/app/img/1.jpg
/sdcard/app/img/2.jpg
/sdcard/app/img/3.jpg
/sdcard/app/img/4.jpg
[...]
/sdcard/app/img/n.jpg
Now I want to create a gallery app to show out these files, I looked
at demo srcs by android sdk, but they always use imgs from
resources...
I decided to try using Bitmapfactory.decodeFile and also
Bitmapfactory.decodestream but both seems not to work fine returning a
NullPointerException
Here you are a little snippet of my app:
Java:
for(int i=0;i<imgsTokens.length;i++)
{
Log.d(""+i,"/sdcard/app/img/"+imgsTokens[i]
+".jpg");
try
{
FileInputStream is = new FileInputStream(new
File("/sdcard/app/img/"+imgsTokens[i]+".jpg"));
BufferedInputStream bis = new
BufferedInputStream(is);
photos[i] = BitmapFactory.decodeStream(is);
bis.close();
is.close();
//photos[i] = BitmapFactory.decodeFile("/
sdcard/app/img/"+imgsTokens[i]+".jpg");
}
catch(Exception e)
{
e.printStackTrace();
}
}
any idea how to fix?
