can't call String.isEmpty() in android

Question

In my android application I can\'t use String.isEmpty() function which is situated in JDK 1.6. Android 2.1 lib doesn\'t have this function in java.lang

Answer 1

You can use android.text.TextUtils.isEmpty() instead. This method also checks to see if the String is null and has been available since API level 1.

if (TextUtils.isEmpty(str)) {
    Log.d(TAG, "String is empty or null!");
}
