There are multiple ways to do this:

***Handle orientation changes by yourself***
Another alternative is to handle the orientation changes by yourself. But this is not considered a good practice.
Add this to your manifest file.
android:configChanges="keyboardHidden|orientation"
for Android 3.2 and later:
android:configChanges="keyboardHidden|orientation|screenSize"
@Override public void onConfigurationChanged(Configuration config) { super.onConfigurationChanged(config); if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) { //Handle rotation from landscape to portarit mode here } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){ //Handle rotation from portrait to landscape mode here } }
***OR Restrict rotation***
You can also confine your activity to portrait or landscape mode to avoid rotation.
Add this to the activity tag in your manifest file:

android:screenOrientation="portrait"
Or implement this programmatically in your activity:
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); }
***OR Save Activity State***
You can save the activity state in onSaveInstanceState.
@Override public void onSaveInstanceState(Bundle outState) { /*Save your data to be restored here Example : outState.putLong("time_state", time); , time is a long variable*/ super.onSaveInstanceState(outState); }
and then use the bundle to restore the state.
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if(savedInstanceState!= null){ /*When rotation occurs Example : time = savedInstanceState.getLong("time_state", 0); */ } else { //When onCreate is called for the first time } }

There are several ways to do this:
**Save Activity State** -----------------------
You can save the activity state in `onSaveInstanceState`.
@Override public void onSaveInstanceState(Bundle outState) { /*Save your data to be restored here Example : outState.putLong("time_state", time); , time is a long variable*/ super.onSaveInstanceState(outState); }
and then use the `bundle` to restore the state.
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
if(savedInstanceState!= null){ /*When rotation occurs Example : time = savedInstanceState.getLong("time_state", 0); */ } else { //When onCreate is called for the first time } }
