Answer 2

Yes, you should be able to use openRawResource to copy a binary across from your raw resource folder to the device.

Based on the example code in the API demos (content/ReadAsset), you should be able to use a variation of the following code snippet to read the db file data.

InputStream ins = getResources().openRawResource(R.raw.my_db_file);

int size = ins.available();

// Read the entire resource into a local byte buffer.
byte[] buffer = new byte[size];
ins.read(buffer);
ins.close();

A copy of your file should now exist in buffer, so you can use a FileOutputStream to save the buffer to a new file.

FileOutputStream fos = new FileOutputStream("mycopy.db");
fos.write(buffer);
fos.close();
