我有一个来自Google地图的示例代码存在问题! 这段代码在我使用eclipse时起作用。我改变了Android工作室,我有一个奇怪的错误。新错误java.lang.IllegalStateException:onSaveInstanceState后无法执行此操作
错误是:(ⅰ没有方法的onSaveInstanceState)

错误是在这条线:
errorFragment.show(getSupportFragmentManager(), LocationUtils.APPTAG);
的代码:
/**
* Verify that Google Play services is available before making a request.
*
* @return true if Google Play services is available, otherwise false
*/
private boolean servicesConnected() {
// Check that Google Play services is available
int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
// If Google Play services is available
if (ConnectionResult.SUCCESS == resultCode) {
// In debug mode, log the status
Log.d(LocationUtils.APPTAG, getString(R.string.play_services_available));
// Continue
return true;
// Google Play services was not available for some reason
} else {
// Display an error dialog
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, this, 0);
if (dialog != null) {
ErrorDialogFragment errorFragment = new ErrorDialogFragment();
errorFragment.setDialog(dialog);
errorFragment.show(getSupportFragmentManager(), LocationUtils.APPTAG);
}
return false;
}
}
THX!
