MainActivity

public class MainActivity extends AppCompatActivity {


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

Answer 1

it shows that your ImageButton cannot inflate the resource that you have provided

android:src="@drawable/minus"

check there is minus.xml missing in your project
