Android: setResult does not return result in parent activity

Question

I started child activity from parent activity using startActivityForResult . After performing the necessary functions in the child activity, I set the result using setResult . But I do not get the result from parent activity from child activity.

Here is my code.

This is how I call my child activity from parent activity.

 Intent i = new Intent(MainActivity.this, Child.class);
    i.putExtra("ID", intID);
    i.putExtra("aID", aID);
    i.putExtra("myMsg", myMsg);
    startActivityForResult(i, 1);

This is how I set the result from my child activity.

 @Override
    public void onBackPressed() {
        super.onBackPressed();
     Intent resultInt = new Intent();
     resultInt.putExtra("Result", "Done");
     setResult(Activity.RESULT_OK, resultInt);
     finish();
}

This is my onActivityResult

   @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 1) {

        if (resultCode == Activity.RESULT_OK) {
            if(data!=null) {
                Toast.makeText(MainActivity.this, "Data received", Toast.LENGTH_SHORT).show();
            }
        }
    }

}

Here, when I check resultCode == Activity.RESULT_OK , gives false. And I also checked for an intent passed outside this if condition, and its return value is null.

 <activity
        android:name=".MainActivity"
        android:label="Main"
        android:parentActivityName=".MainPage"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="org.mydomain.mydomain.MainPage" />
    </activity>
    <activity
        android:name=".Child"
        android:label="Child"
        android:parentActivityName=".MainActivity"
        android:theme="@style/AppTheme1">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="org.mydomain.mydomain.MainActivity" />
    </activity>

• You need to create a variable to receive the data that was passed from childActivity .

    @Override
          protected void onActivityResult(int requestCode, int resultCode, Intent data) {
              super.onActivityResult(requestCode, resultCode, data);
      if (resultCode == Activity.RESULT_OK) {
            if (requestCode == 1) {
               String ReceiveData = data.getStringExtra("Result"); // you have to receiveData
                  if(ReceiveData !=null) {
                      Toast.makeText(MainActivity.this, "Data received", Toast.LENGTH_SHORT).show();
                  }
              }
          }
  
      }
