Как исправить сбой Android Studio?

Я работаю в Android Studio, и у меня есть эта ошибка:

ERROR: Could not find method compile() for arguments [com.google.android.gms:play-services-analytics:11.8.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Когда я открываю свой проект в Android Studio, программа внезапно закрывается.

Мой код:

public class MainActivity extends Activity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
