Bundle is null after setting it in Intent

Question

I know there are questions like: android-intent-bundle-always-null and intent-bundle-returns-null-every-time but there is no correct answer.

In my Activity 1

Answer 1

Activity 1

Intent intent = new Intent(getApplicationContext(), MapViewActivity.class);

        Bundle b = new Bundle();
         b.putBoolean("asdf", true);
         b.putInt(AppConstants.ID_KEY, id);
         intent.putExtras(b);

         startActivity(intent);

Activity 2

Bundle extras = getIntent().getExtras();

 boolean bool = extras.getBoolean("asdf");
 int m_int = extras.getInt(AppConstants.ID_KEY,-1);

Answer 2

I am not sure what "Info" is for, but I suggest making the most basic passing of data from one activity to another first before involving other data objects.

Activity1

    Intent intent = new Intent(Activity1.this, Activity2.class);
    intent.putExtra("asdf", true);
    info.write(intent);
    startActivity(intent);

Activity2

    Bundle bundle = getIntent.getExtras();
    if (bundle!=null) {
        if(bundle.containsKey("asdf") {
            boolean asdf = bundle.getBooleanExtra("asdf");
            Log.i("Activity2 Log", "asdf:"+String.valueOf(asdf));
        }
    } else {
        Log.i("Activity2 Log", "asdf is null");

    }
