Java – lambda expression – source 1.7 not supported (Android studio)

See English answer > is it possible to use Java 8 for Android development? I tried to run my android project in Android studio, but I couldn't

I received this error:

Error:(23, 47) error: lambda expressions are not supported in -source 1.7
(use -source 8 or higher to enable lambda expressions)
Error:Execution Failed for task ':app:compileDebugJava'.
> Compilation Failed; see the compiler error output for details.

I use JDK 1.8

Do you know why? Any regrouping

PS: there are several similar problems in stack, but this problem is not solved. Please understand the problem before marking duplicate

resolvent:

This is the solution:

Android cannot be built on JDK 1.8; And lambda expressions cannot be used under JDK 1.8

The solution is to return JDK 1.7 and avoid using lambda symbols. Instead:

button.setOnClickListener((v) -> {


                    Intent newIntent = new Intent(MainActivity.this, NextActivity.class);
                    MainActivity.this.startActivity(newIntent);
                }
            });

We must use this:

       button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                Intent newIntent = new Intent(MainActivity.this, NextActivity.class);
                MainActivity.this.startActivity(newIntent);
            }
        });
