Hi there,
@Ralph - I do it my way because it seems to me that multiple calls to
getResources() is generally considered to be a bad thing (read it online),
and like Michael said I want to make sure my next Image loads without fail.
That and the fact that in an actual app, you would indeed have quite a few
calls to getResources(). In fact, previously my code used to be that exact
same line, which is why the app crashed when loading the fourth or fifth
image. Supposedly, the GC does not clear the bitmap that is not on screen
fast enough (not sure if it does it at all).
@Michael - Yes, this is exactly the reason why I have done it this way.
Please correct me if I am wrong about the multiple calls to getResources(),
as I have just recently started Android dev.
I also cache the context by using Context context=getApplicationContext();
as that too is used in my app. Does this leak the context in anyway? I know
its off topic but just want to be clear.
Regards,
Sorab

I've run into this issue a lot myself when working with largish
bitmaps. The GC for bitmaps is pretty rubbish - especially if your app
has to run on older phones.

Why do you do it that way:
h1 = BitmapFactory.decodeResource(res, R.drawable.help1_l);
ImageView im = (ImageView) findViewById(R.id.helpImage);
im.setImageBitmap(h1);
and not like this:
im.setImageDrawable(getResources().getDrawable(R.drawable.help1_l))
take also a look at:
