Ok, it was a bad subject. I just needed a way to provide a Bitmap drawable
in my App's memory (not on sdcard) to the SearchWidget suggestion handling
code. Here's the answer for anyone who needs to provide their own image
that isn't stored somewhere as a file and easily accessible via one of the
other content providers that are already there.
I created a ContentProvider in my app. The key methods look like the
following:
@Override
public ParcelFileDescriptor openFile(Uri uri, String mode)
throws FileNotFoundException {
ParcelFileDescriptor[] pipe=null;
try {
pipe=ParcelFileDescriptor.createPipe();
String bmapId = uri.getLastPathSegment();
IconInfo ai = getIconInfo.lookup(Integer.parseInt(bmapId));
if (ai == null)
throw new FileNotFoundException("Bitmap "+bmapId+" not found");
Bitmap bitmap = ((BitmapDrawable)ai.icon).getBitmap();
if (bitmap == null)
throw new FileNotFoundException("Drawable is not Bitmap");
// The following task/thread is needed if the bmap is larger than 64kb
new BitmapCopyTask(bitmap,
new AutoCloseOutputStream(pipe[1])).execute(null,null
,null);
}
catch (IOException e) {
MyLog.d(getClass().getSimpleName(), "Exception opening pipe: %s",
e.getMessage());
throw new FileNotFoundException("Could not open pipe for: "
+ uri.toString());
}
return(pipe[0]);
}
class BitmapCopyTask extends AsyncTask<Void,Void,Void> {
OutputStream out;
Bitmap bmap;
BitmapCopyThread(Bitmap bmap, OutputStream out) {
this.bmap = bmap;
this.out = out;
}
@Override
protected Void doInBackground(Void... arg0) {
bmap.compress(Bitmap.CompressFormat.PNG, 100, out);
return null;
}
}
I also put the following provider definition in my manifest file:
<provider android:name=".IconProvider"
android:exported="false"
android:authorities="org.example.provider.iconlist.icon" />
