[android-developers] Re: How to READ a MODE_WORLD_READABLE file from ANOTHER application

Thanks again!

Actually, this seems to be working on the ContentProvider now:

public AssetFileDescriptor openAssetFile(Uri uri, String mode) {
String fileName = "asset_text_orig.txt";
URI uri1 = URI.create(fileName);
AssetFileDescriptor parcel = this.openAssetFile(uri1, mode); //
for testing purposes, I hardwired this to uri1 >
"asset_text_orig.txt";
return parcel;
}

Now, how do I read this from an app?

String packageName = "com.example.text.cp";
FileInputStream fstream = new FileInputStream("content://" +
packageName); // there is only one kind of file exposed
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine = br.readLine();

...

Or should I include openAssetFile(Uri uri, String mode) at the end of
the uri goint to FileInputStream?

Thank you very much for your help so far.
