Usage

From source file:Main.java

public static String readRawTextFile(Context ctx, int resId) {
    InputStream inputStream = ctx.getResources().openRawResource(resId);

    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

    int i;/*from w  w w  .j ava  2 s  .  c om*/
