I have same error :
"错误: 找不到符号
SplashScreen.show(this, getReactInstanceManager()); "
I have already add compile project(':rn-splash-screen') in build.gradle

my MainActivity.java:

import com.reactnativenavigation.controllers.SplashActivity;

import android.graphics.Color;
import android.os.Bundle;

import com.facebook.react.ReactInstanceManager;
import com.facebook.react.bridge.ReactContext;
import com.mehcode.reactnative.splashscreen.SplashScreen;
import com.mehcode.reactnative.splashscreen.SplashScreenPackage;

public class MainActivity extends SplashActivity {

@OverRide
protected void onCreate(Bundle savedInstanceState) {
SplashScreen.show(this, getReactInstanceManager());
super.onCreate(savedInstanceState);
}
}
