Alternative to java.nio.file

I am using Android Studio 2.3.1 and jdk 1.8 for this project.

I am importing a project and using 'java.nio.file.Files' and 'java.nio.file.Paths'.

The "java.nio.file" package does not exist in Java 8.

Also Android Studio doesn't let you select jdk 1.7.

What can I do with this code?

public void toFile(final String path) throws IOException {
    Files.write(Paths.get(path), toBuffer());
}

and this code

public static Source fromFile(final String path) throws IOException {
    return fromBuffer(Files.readAllBytes(Paths.get(path)));
}

** (Unable to resolve files and paths)

thank

Android does not offer all the classes that "regular Java" has to offer. Files are one of the classes that Android doesn't offer.

You can take a look at the classes available in Android here: http://developer.android.com/reference/classes.html

So, unfortunately, you need to use other functions / classes to implement the same functionality.

I found this library which claims to be



NNIO: Java NIO replacement library.2

but i think you should use guava instead to implement the same functionality as many first class applications has a large community.

Edit: java.nio.file is supported as Android Ovi preview. https://developer.android.com/reference/java/nio/file/package-summary.html
