Re: [android-developers] Reading from another app
Latimerius,
Do you mean something like this? (I ripped this from another site)
Resources res =
context.getPackageManager().getResourcesForApplication(com.example.foo)
I was doing something very similar already (posted below), though thought it
was a bit of a hack.
final String packName = com.jash.cp_source_two;
String mDrawableName = a1;
try
{
PackageManager manager = getPackageManager();
Resources resources = manager.getResourcesForApplication(packName);
int mDrawableResID = resources.getIdentifier(mDrawableName,
drawable,packName);
Drawable myDrawable = resources.getDrawable( mDrawableResID );
if( myDrawable != null )
{
image = (ImageView) findViewById(R.id.imageView1);
image.setImageDrawable(myDrawable );
}
}
catch (PackageManager.NameNotFoundException e)
{
Toast.makeText(getBaseContext(), error = +e,
Toast.LENGTH_LONG).show();
}
Is there any reason to use your method over what I already had?
Also, July was a big month and Mark Murphy posts a lot! Do you happen to
remember roughly what the topic was to help narrow down the search ;)
Thanks a great deal for this.
Russ

Latimerius,
So how do you directly access them from the assets folder?
You have to know the name of the package whose images you want to use but
that shouldn't be a problem in your case if I understand correctly. Then you
just pass it to createPackageContext() which you call on one of your
Activities (I use the main one but I guess it probably doesn't matter much
which one you pick) to retrieve a Context of the package containing images.
After that, everything works the same as when working with this package's
resources - you call getResources() or getAssets() on the Context etc.
Doing it this way, are the images available to anyone who has root access?
i.e. can they steal your images?
Then can do that anytime anyway. Everybody seems surprised to learn that (I
know I was!) but anybody can access your assets and resources any time they
please with just minor inconvenience, and they DON'T need root for that.
(There was a thread about this on this group last July I think, Mark Murphy
had some insights back then so look it up if you're interested.)
Why do you use assets? For ease, or for some other reason? I thought it would
be better to have them in the res folders so that the diff screen sizes still
get used, e.g. ldpi/hdpi etc folders?
I use assets because the program I work on is a game, or a toy, which uses
custom rules to adapt to different screen sizes and densities. We started
off using resources but quickly found out that Android's built-in scaling
etc. was just ruining our art and throwing off our screen layout algorithms.
Of course, even if res folders didn't work for us with our special needs,
they can still work splendid for you. In that case, just go for res, I have
no first-hand experience with that but I don't see any reason why it
shouldn't work.

Re: [android-developers] Reading from another app
RichardC looking through my phone using astro file manager, I can't find any apps that have been installed? Is that because I am not rooted? What folder would/should they be in if I can see them? Or do you mean the apk is readable before its installed? In that case, how do you save an apk from Google play without it installing?

Re: [android-developers] Reading from another app - resources/assets (Take 2!)
Using the package name and a resource ID you can load resources from another APK. That's how Launcher loads icons, strings and widget resources for instance. All the APIs you need are in the Resources class if I recall properly.
