Method 1

res/raw directory, such as cwj.dat1 binary file, we can read it directly

InputStream is=context.getResources().openRawResource(R.raw.cwj);

Method 2

In the assets folder in the project root, for example, assets/ cwj.dat, we use the following code

AssetManager am = context.getAssets();
InputStream is = am.open(cwj.dat);
