Invalid member type plugin causing build failure - android-studio

Question

Today, I opened my Android Studio and tried to build an APK but without changing anything, I got this error: Invalid type in member Type: com/google/gms/googleservices/GoogleServicesPlugin$PluginType; android studio
and here are some other errors that the compiler throws at me:
I tried deleting the 0.jar file from the respective folder and see if that fixes one of the errors but nothing. Any ideas? I don't get what I should change or what I did wrong since I didn't mess around with anything.
EDIT:
public class DokkanCardsApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
#Override
public void onActivityCreated(Activity activity, Bundle bundle) {
// Fix for the Full Screen Activities bug with Android O
if(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
}
#Override
public void onActivityStarted(Activity activity) {
}
#Override
public void onActivityResumed(Activity activity) {
}
#Override
public void onActivityPaused(Activity activity) {
}
#Override
public void onActivityStopped(Activity activity) {
}
#Override
public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {
}
#Override
public void onActivityDestroyed(Activity activity) {
}
});
}
}

You can change your view from Android to Project from top of the left side of your Android Studio and delete .gradle file maybe it helps you.
And I think you have to enable multidex in your application too.
Do it like this:
android {
defaultConfig {
multiDexEnabled true
}
}
Second, add this to four dependencies:
dependencies {
compile 'com.android.support:multidex:1.0.1'
}
And finally make an application class like this:
public class MyApplication extends Application {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
}
And finally don't forget to add your application class into your manifest like this:
<application
android:name=".MyApplication"
UPDATE:
Your application class should be like this:
public class DokkanCardsApplication extends Application {
#Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
#Override
public void onCreate() {
super.onCreate();
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
#Override
public void onActivityCreated(Activity activity, Bundle bundle) {
// Fix for the Full Screen Activities bug with Android O
if(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
}
#Override
public void onActivityStarted(Activity activity) {
}
#Override
public void onActivityResumed(Activity activity) {
}
#Override
public void onActivityPaused(Activity activity) {
}
#Override
public void onActivityStopped(Activity activity) {
}
#Override
public void onActivitySaveInstanceState(Activity activity, Bundle bundle) {
}
#Override
public void onActivityDestroyed(Activity activity) {
}
});
}
