I am using a fragment for my application.and I also add a bundle into my fragments but when I want to get the added String from the bundle the compiler shows me a null pointer error like as follows
Process: com.softmaker.gazi_opu.personalhealthcare, PID: 3253
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String java.lang.String.toString()' on a null object reference

And my added code and getting the added data code are given bellow
public static GeneralInformationFragment getInstance(String profileID){
Bundle bundle = new Bundle();
bundle.putString("profileId",profileID);
GeneralInformationFragment generalFragment = new GeneralInformationFragment();
generalFragment.setArguments(bundle);
return generalFragment;
}
Now for getting data from the this fragment within onCreateMethod
String id = getArguments().getString("profileId");
Log.e("ID :", "" + id.toString());
Can anyone suggest me. where am I making mistake ?
I always pass data like this and work perfectly :
public class CategoryResultFragment extends BaseListFragment {
private static final String CATEGORY_ID = "EXTRA_CATEGORY_ID";
private static final String CATEGORY_SLUG = "EXTRA_CATEGORY_SLUG";
private String mCategoryId;
private String mCategorySlug;
public static CategoryResultFragment newInstance(String categoryId, String categorySlug) {
Bundle bundle = new Bundle();
bundle.putString(CATEGORY_ID, categoryId);
bundle.putString(CATEGORY_SLUG, categorySlug);
CategoryResultFragment categoryResultFragment = new CategoryResultFragment();
categoryResultFragment.setArguments(bundle);
return categoryResultFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (getArguments() != null) {
mCategoryId = getArguments().getString(CATEGORY_ID);
mCategorySlug = getArguments().getString(CATEGORY_SLUG);
}
return super.onCreateView(inflater, container, savedInstanceState);
}
}
