I am using retrofit to get sample data from "https://jsonplaceholder.typicode.com/comments" but I am getting this error:

My MainActivity.java is:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
requestPermissions(new String[]{Manifest.permission.INTERNET},0);
textView = findViewById(R.id.text_view);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://jsonplaceholder.typicode.com/")
.addConverterFactory(GsonConverterFactory.create())
.build();
JsonPlaceHolderApi jsonPlaceHolderApi = retrofit.create(JsonPlaceHolderApi.class);
Call<List<Comments>> call= jsonPlaceHolderApi.getComments();
call.enqueue(new Callback<List<Comments>>() {
@Override
public void onResponse(Call<List<Comments>> call, Response<List<Comments>> response) {
if(!response.isSuccessful()){
textView.setText("error :" +response.code());
return;
}
List<Comments> comments =response.body();
String answer="";
for(Comments c:comments){
answer = "postId"+c.getPostId()+" \n"+"id :" +c.getId()
+"\nname"+ c.getName()+"\nemail "+c.getEmail()+"\n comment"+c.getComment()+"\n";
}
textView.setText(""+answer);
}
@Override
public void onFailure(Call<List<Comments>> call, Throwable t) {
textView.setText(t.getMessage());
}
});
}
and My JsonPlaceHolderApi code is:
public interface JsonPlaceHolderApi {
@GET("comments")
Call<List<Comments>> getComments();
}
I have also added Internet permission in Manifest file. But I still don't know why this error is coming.
add
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
in your gradle file.
