I think you want to ship you application by creating database outside , these are good tutorial to add database to your application , and these are few good tutorials to start with

If your device is an emulator or is a physical device connected thru USB, you can use this command-line:

adb push c:\local_path\myfile.db /path_on_the_device/myfile

You better add db into assets and copy it into sd or internal storage. Here is some code snippet for you

private void CopyFileFromAssets() {
    AssetManager asm = getAssets();
    String[] files = null;
    try {
        files = asm.list("");
    } catch (IOException e) {
        Log.e("tag", e.getMessage());
    }
    for(String filename : files) {
        InputStream in = null;
        OutputStream out = null;
        try {
          in = asm.open(filename);
          //you can even create folder to put your file
          out = new FileOutputStream("/sdcard/" + filename);
          copyFile(in, out);
          in.close();
          in = null;
          out.flush();
          out.close();
          out = null;
        } catch(Exception e) {
            Log.e("tag", e.getMessage());
        }       
    }
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
      out.write(buffer, 0, read);
    }
}

Hope this can help

Go to file explorer - data - data - your pkg name - select database and click on push a file onto the device.

First remove the db extension.

1.then select DDMS

2.then select emulator from device tab

3.move to data/data//databases

4.now push file into emulator using the top-right open in window.

5.Now run the app.

Thank you.
