问题 I am getting following Exception on Android 2.2.1: java.lang.NoSuchMethodError: java.lang.String.isEmpty I am calling text.isEmpty from Scala. Any idea, how to solve this? 回答1: Use JRE/JDK 1.5, which did not have an isEmpty method on String . This will avoid situations where Scala uses 1.6's isEmpty instead of its own. If you have Java libraries as well, be sure to pick ones compatible with 1.5. 回答2: java.lang.String.isEmpty() was added in Gingerbread (2.3). You will have to write your own

These methods will in turn call other methods within this project. Although the method calling is succeeding, an InvocationTargetException caused by NoSuchMethodError is being thrown.
