Solution 1:[1]

As far as I can tell:

 Property                    java.lang.String    android::String8
 ================================================================
 language                    Java                C++
 Unicode                     yes                 yes
 char width                  16                  8
 encoding                    UTF-16              UTF-8
 mutability                  immutable           mutable
 bunch of file path methods  no                  yes
 attitude to Darwin          indifferent         annoyed (line 47)

They are both Unicode string types; the similarities seem to end there.

The more important difference is Java String consumes aproximately twice the memory than String8 and other alternatives for the same text.

Also Java String is inmutable: so you cannot modify its contents and this have some good... and... some very bad implications (although you have StringBuilder and other alternatives).
