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 this TextUtils.isEmpty(str). This is available since API level 1 or You can create you own method like below

public boolean isEmpty(CharSequence str) {
    if (str == null || str.length() == 0)
        return true;
    else
        return false;
}
