I spoke too soon.
It works ONCE and then it
12-04 22:38:05.330: WARN/System.err(763):
java.io.FileNotFoundException: This file can not be opened as a file
descriptor; it is probably compressed
This is the routine in the Content Provider:
@Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode) {
String fileName = "asset_text.txt";
AssetManager assetManager = this.getContext().getAssets();
AssetFileDescriptor afd = null ;
try {
afd = assetManager.openFd(fileName);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return afd;
}
What I don't understand is why did it work once and no more? The file
is still there, intact. Does it get compressed on the device? How can
I read it reliably?
Thanks.
