diff between Context.getResources().getString() and Context.getString()

in the refrences ,I did't know what's its mean.

Context.getResources().getString() Return the string value associated with a particular resource ID. It will be stripped of any styled text information.
Context.getString() Return a localized string from the application's package's default string table.

so i got the sources ,found that they are totally the same.

/android_opensource/frameworks/base/core/java/android/content/Context.java
...
141 /**
142 * Return a localized string from the application's package's
143 * default string table.
144 *
145 * @param resId Resource id for the string
146 */
147 public final String getString(int resId) {
148 return getResources().getString(resId);
149 }
...
