I'm displaying the current location address on the screen. I was told to add (android:configChanges="keyboardHidden|orientation") in manifest file to store the context(address).It works fine,but after adding this line, the screen orientation is not changing . If i remove this line, then the orientation works good but the address disappears on changing the orientation. If anyone knows how to solve this, then pls comment on it.

Thank you.

Use android:configChanges="orientation|screenSize" in manifest

you need to save the data, as the orientation gets changed the screen is drawn new. i.e. onDestroy gets called and then onCreate() gets called again. The following link has more info on how to save the data.

Saving Android Activity state using Save Instance State

Restoring state of TextView after screen rotation?

  • I've gone through these sites. Accordingly if i edit my code, then address gets stored, but the orientation remains the same, horizontal or vertical. – Spoorti Apr 19 '11 at 07:05

When you rotate the screen, Android redraws the entire activity to for the new orientation. This involves calling onCreate() again, which is why your address is disappearing. Take a look at onSaveInstanceState, an Activity method you can override to store anything you need to hang on to when the activity is closed and reopened. Just package up your data in the Bundle, and then you have access to it again in the Bundle in onCreate().

This sounds overly complex, but this is the correct way to handle it. Android can close your activity for any number of reasons - the screen rotation is just a really easy one to test. If it works for the rotation, then it'll likely work for other situations like low memory, etc.

  • I ve used onSaveInstanceState (Bundle savedInstanceState) and onRestoreInstanceState(Bundle savedInstanceState), but still location address is disappearing. – Spoorti Apr 19 '11 at 06:46
  • @Spoorti Could you post code showing how you're saving / restoring the address currently? – RawwrBag Apr 19 '11 at 06:49
  • @Override public void onSaveInstanceState (Bundle savedInstanceState) { savedInstanceState.putString("MyString", result.toString()); super.onSaveInstanceState(savedInstanceState); } @Override public void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); String myString = savedInstanceState.getString("MyString"); } – Spoorti Apr 19 '11 at 06:58

  • In the above code, result.toString() gives the location address. – Spoorti Apr 19 '11 at 06:59
