Я проверил все, я уверен, что мой код верен на стороне действий, но я не могу понять ошибку, я пытался проверить AndroidManifest. xml, но я не вижу проблемы. Я получаю эту ошибку при выходе из эмулятора:

Вот мой простой MainActivity
public class MainActivity extends AppCompatActivity {
private Button searchButton, plannerButton;
@Override
public void onCreate(@Nullable Bundle savedInstanceState ) {
super.onCreate (savedInstanceState);
setContentView (R.layout.activity_main);
searchButton = (Button) findViewById (R.id.main_search);
plannerButton = (Button) findViewById (R.id.main_planner);
searchButton.setOnClickListener (new View.OnClickListener () {
@Override
public void onClick(View v) {
openActivity2();
}
});
}
public void openActivity2(){
Intent intent = new Intent (this, PlannerActivity.class);
startActivity(intent);
}
}
And here my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

</RelativeLayout>
and here is the second Activity I want to go to once I click on search button, then I'll do the same with planner button to go to an other activity
public class PlannerActivity extends AppCompatActivity {
TextView titlepage, subtitlepage, endpage;
Button btnAddNew;
DatabaseReference reference;
RecyclerView ourdoes;
ArrayList<MyDoes> list;
DoesAdapter doesAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_planner);
titlepage = findViewById(R.id.titlepage);
subtitlepage = findViewById(R.id.subtitlepage);
endpage = findViewById(R.id.endpage);
btnAddNew = findViewById(R.id.btnAddNew);
// import font
Typeface MLight = Typeface.createFromAsset(getAssets(), "fonts/ML.ttf");
Typeface MMedium = Typeface.createFromAsset(getAssets(), "fonts/MM.ttf");
// customize font
titlepage.setTypeface(MMedium);
subtitlepage.setTypeface(MLight);
endpage.setTypeface(MLight);
btnAddNew.setTypeface(MLight);
btnAddNew.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent a = new Intent(PlannerActivity.this,NewTaskAct.class);
startActivity(a);
}
});
// working with data
ourdoes = findViewById(R.id.ourdoes);
ourdoes.setLayoutManager(new LinearLayoutManager (this));
list = new ArrayList<MyDoes>();
// get data from firebase
reference = FirebaseDatabase.getInstance().getReference().child("DoesApp");
reference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
// set code to retrive data and replace layout
for(DataSnapshot dataSnapshot1: dataSnapshot.getChildren())
{
MyDoes p = dataSnapshot1.getValue(MyDoes.class);
list.add(p);
}
doesAdapter = new DoesAdapter(PlannerActivity.this, list);
ourdoes.setAdapter(doesAdapter);
doesAdapter.notifyDataSetChanged();
}
@Override
public void onCancelled(DatabaseError databaseError) {
// set code to show an error
Toast.makeText(getApplicationContext(), "No Data", Toast.LENGTH_SHORT).show();
}
});
}
}
