Android access to files under assets

Assets often can put some relatively large resources, for these resources how we access.

Steps

1. Get Assetmanager.
Assetmanager am = getresources (). Getassets ();
2. Open the corresponding input stream with the Assetmanager's open (String FilePath) method.
InputStream is = Am.open (assetsfilename);
