Happy to know that java introduced Lambda expressions in java version 8.
I was working in android studio. And I noticed that
DialogInterface.OnClickListener() was showing underline and became grey colored as below:
So, I did
alter + enter on that line and found option to replace the code with Lambda Expressions, as below:
Which resulted in something below:
After running the code it showed me this error:
Error:(160, 69) error: lambda expressions are not supported in -source
1.7 (use -source 8 or higher to enable lambda expressions)
But I am already using java
jdk1.8.0_31. Is there anything else, I need to install ?
Can anyone help me out please..
You cannot compile Java 8 sources for Android, because Android SDK does not support Java 8 yet.
But there is one way to use Lambdas in your code – RetroLambda. This is a little hack that allows you to use some of the features of Java 8 in your project.
I don’t think
Android development is ready yet for
Android Studio supports the compile level
Java 7 whether you installed
Java 7 or
Java 8. So, if you want to use new features of
Java 8, I think you have to wait
Android Studio to support
compile level Java 8.
