Hi,

The only way to convert between an object array of Strings and QStringList is to do it manually, that is, iterate through the list/array and copy the string.
For iterating through the object array, see GetObjectArrayElement() and GetArrayLength()[1] (accessible through the QAndroidJniEnvironment class)

An easier way, if you can change the java function (or write a wrapper), is to make the java function return the string-array as one string and then call split on the QString :)
