App Crashes on Splash Screen throwing Null Pointer

Question

According to Playstore ANR & Crashes the app is throwing null pointer on SplashScreen oncreate. I've checked the functioning and it looks good at my end. Not all phones are crashing however are.

My SplashActivity.java

package com.example.app;

import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Html;
import android.util.Log;

public class SplashActivity extends AppCompatActivity {

    String path = "";
    String banner = "";
    String title = "";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        if(getIntent().getExtras() != null){
            Log.e("splash", "from push link");
            path = getIntent().getExtras().getString("link");
            banner = getIntent().getExtras().getString("bannerImage");
            title = getIntent().getExtras().getString("title");
            String link = String.valueOf(Html.fromHtml(Html.fromHtml(path).toString()));
            String imgurl = String.valueOf(Html.fromHtml(Html.fromHtml(banner).toString()));
            Log.e("link----", "link--" + link);

            SharedPreferences pref = getApplicationContext().getSharedPreferences("Push", MODE_PRIVATE);
            SharedPreferences.Editor editor = pref.edit();
            String pushtitle = pref.getString("pushtitle", "");

            StringBuilder sb = new StringBuilder();
            sb.append(pushtitle).append(title).append(",");
            Log.e("pushtitle===========", sb.toString());
            editor.putString("pushtitle", sb.toString());

            String links = pref.getString("link", "");
            StringBuilder sb2 = new StringBuilder();
            sb2.append(links).append(link).append(",");
            Log.e("link===========", sb2.toString());
            editor.putString("link", sb2.toString());

            String imgurlstr = pref.getString("imgurl", "");
            StringBuilder sb3 = new StringBuilder();
            sb3.append(imgurlstr).append(imgurl).append(",");
            Log.e("imgurl===========", sb3.toString());
            editor.putString("imgurl", sb3.toString());

            editor.commit();
        }
        int secondsDelayed = 1;
        new Handler().postDelayed(new Runnable() {
            public void run() {
                Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                if (path  != "") {
                    Log.e("splash", "path==" + path);
                    intent.putExtra("link", String.valueOf(Html.fromHtml(Html.fromHtml(path).toString())));
                }
                startActivity(intent);
                finish();
            }
        }, secondsDelayed * 1000);
    }
}

The playstore crashes report as following. java.lang.NullPointerException com.example.app.SplashActivity.onCreate

java.lang.RuntimeException: at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2984) at android.app.ActivityThread.handleLaunchActivity (ActivityThread.java:3045) at android.app.ActivityThread.-wrap14 (ActivityThread.java) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1642) at android.os.Handler.dispatchMessage (Handler.java:102) at android.os.Looper.loop (Looper.java:154) at android.app.ActivityThread.main (ActivityThread.java:6776) at java.lang.reflect.Method.invoke (Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run (ZygoteInit.java:1496) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1386) Caused by: java.lang.NullPointerException:

EDIT: Debugging the App I got the below error:
