Assignments are not expressions - Kotlin

Question

I\'m refactoring my project built with Java to Kotlin and to copy database from sqlite assets table I\'m doing this and it works correctly.

private void copy         


        

Answer 1

Change it to:

 mLength = mInput.read(mBuffer)
 while (mLength > 0) { 
        mOutput.write(mBuffer, 0, mLength)
        mLength = mInput.read(mBuffer)
    }

Answer 2

This is a work around to your problem:

while ({mLength = mInput.read(mBuffer); mLength}() > 0) {
    mOutput.write(mBuffer, 0, mLength)
}
