切换到Activity1（RecyclerView）切换到Activity2（RecyclerView）

Question

Please help me into this problem. I have a 2 activity with RecyclerView each of them. My problem, when I open the Activity1 and pressed back then open the Activity2, it loads but when scrolling the application is unfortunately closing.

Each activity has Adapter and Holder. Did I forgot to finish the activity onBackPressed? What code should I put and where to put? Thank you!

Activity.java

 package com.bne;

    public class Festivals extends AppCompatActivity {

        String[] names;
        String[] location;
        int[] images ={};
        String[] date;
        String[] about;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.festivals);
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
            setSupportActionBar(toolbar);

            getSupportActionBar().setDisplayHomeAsUpEnabled(true);
            getSupportActionBar().setDisplayShowHomeEnabled(true);

            RecyclerView recyclerView = (RecyclerView) findViewById(R.id.Festivals);

            names = getResources().getStringArray(R.array.festival_name);
            location = getResources().getStringArray(R.array.festival_location);
            date = getResources().getStringArray(R.array.festival_date);
            about = getResources().getStringArray(R.array.festival_about);

            recyclerView.setLayoutManager(new LinearLayoutManager(this));
            recyclerView.setItemAnimator(new DefaultItemAnimator());

            FestivalsAdapter adapter = new FestivalsAdapter(this, names, location, images, date, about);
            recyclerView.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL));
            recyclerView.setAdapter(adapter);

        }

        @Override

Answer 1

It seem you have large size of images in your resources which is causing this error when you are loading in your adapter.

Only use images of the size required by your layout or else this error would cause often.
