I'm trying to use this code that I've seen on multiple posts throughout stackoverflow
public static Bitmap loadBitmap(Context context, String filename) throws IOException {
AssetManager assets = context.getResources().getAssets();
InputStream buf = new BufferedInputStream((assets.open("drawable/" + filename)));
Bitmap bitmap = BitmapFactory.decodeStream(buf);
return bitmap;
}
but I'm getting a "FileNotFoundException: drawable/filename". I definitely have a file with the name I'm trying to load in the drawable folders. Any ideas? I've tried with and without the file extension, tried putting the file into every folder and tried multiple phones/emulator.
The AssetManager
is intended to access the data in the assets
folder. So in your example, it looks for assets/drawable/filename
and does not find anything.
To get a resource from drawable, one should use
Drawable d = getResources().getDrawable(R.drawable.filename);
If you're sure it's a bitmap, you can do it like so:
Bitmap bm = ((BitmapDrawable)getResources()
.getDrawable(R.drawable.filename)).getBitmap();
You can do it like this...
// load image from Assets folder
// get input stream
InputStream mIms = getAssets().open("ic_launcher.png");
// load image as Drawable
Drawable mDraw = Drawable.createFromStream(mIms, null);
// set image to ImageView
mIms.setImageDrawable(mDraw);
