Orientation Changes In Android

I am using getLastNonConfigurationInstance() to save object while changing orientation in my activity. now it is deprecated. What is the best way of alternative? the documentation

Solution 1:

For saving state, use onSaveInstanceState(Bundle savedInstanceState). You can restore saved state either in onCreate or in onRestoreInstanceState(Bundle savedInstanceState).

@OverridepublicvoidonSaveInstanceState(Bundle savedInstanceState) {
      // Save UI state changes to the savedInstanceState.// This bundle will be passed to onCreate if the process is// killed and restarted.
      savedInstanceState.putBoolean("MyBoolean", true);
      savedInstanceState.putDouble("myDouble", 1.9);
      savedInstanceState.putInt("MyInt", 1);
      savedInstanceState.putString("MyString", "Hello Android");
      super.onSaveInstanceState(savedInstanceState);
    }

The Bundle is essentially a way of storing a Key-Value Pair" map, and it will get passed in to onCreate and also onRestoreInstanceState where you would extract the values like this:

@OverridepublicvoidonRestoreInstanceState(Bundle savedInstanceState) {
      super.onRestoreInstanceState(savedInstanceState);
      // Restore UI state from the savedInstanceState.// This bundle has also been passed to onCreate.booleanmyBoolean= savedInstanceState.getBoolean("MyBoolean");
      doublemyDouble= savedInstanceState.getDouble("myDouble");
      intmyInt= savedInstanceState.getInt("MyInt");
      StringmyString= savedInstanceState.getString("MyString");
    }
