Invalid column Contact_ID ContactsContract.Contacts

I am trying the following code to `AutoComplete` contact details as the user types for my android app. ``` public class MakePayment extends Activity { private AutoCompleteTextView mAuto; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.makepayment); mAuto = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextViewTest); ContentResolver content = getContentResolver(); Cursor cursor = content.query(ContactsContract.Contacts.CONTENT_URI, PEOPLE_PROJECTION, null, null, null); ContactListAdapter adapter = new ContactListAdapter(this, cursor); mAuto.setAdapter(adapter); } public static class ContactListAdapter extends CursorAdapter implements Filterable { public ContactListAdapter(Context context, Cursor c) { super(context, c); mContent = context.getContentResolver(); } @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { final LayoutInflater inflater = LayoutInflater.from(context); final TextView view = (TextView) inflater.inflate( android.R.layout.simple_dropdown_item_1line, parent, false); view.setText(cursor.getString(3)); return view; } @Override public void bindView(View view, Context context, Cursor cursor) { ((TextView) view).setText(cursor.getString(3)); } @Override public String convertToString(Cursor cursor) { return cursor.getString(3); } @Override public Cursor runQueryOnBackgroundThread(CharSequence constraint) { if (getFilterQueryProvider() != null) { return getFilterQueryProvider().runQuery(constraint); } StringBuilder buffer = null; String[] args = null; if (constraint != null) { buffer = new StringBuilder(); buffer.append("UPPER("); buffer.append(ContactsContract.Contacts.DISPLAY_NAME); buffer.append(") GLOB ?"); args = new String[] { constraint.toString().toUpperCase() + "*" }; } return mContent.query(ContactsContract.Contacts.CONTENT_URI, PEOPLE_PROJECTION, buffer == null ? null : buffer.toString(), args, null); } private ContentResolver mContent; } private static final String[] PEOPLE_PROJECTION = new String[] { ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Email.DATA, ContactsContract.Contacts.DISPLAY_NAME, }; } ``` But my app shuts down giving the following errors: ``` 06-21 10:33:26.970: E/AndroidRuntime(31086): FATAL EXCEPTION: main 06-21 10:33:26.970: E/AndroidRuntime(31086): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.MyApp/com.MyApp.MakePayment}: java.lang.IllegalArgumentException: Invalid column contact_id 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1713) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.ActivityThread.startActivityNow(ActivityThread.java:1541) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.LocalActivityManager.moveToState(LocalActivityManager.java:127) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.LocalActivityManager.startActivity(LocalActivityManager.java:339) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.widget.TabHost$IntentContentStrategy.getContentView(TabHost.java:696) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.widget.TabHost.setCurrentTab(TabHost.java:328) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.widget.TabHost$2.onTabSelectionChanged(TabHost.java:134) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.widget.TabWidget$TabClickListener.onClick(TabWidget.java:518) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.view.View.performClick(View.java:2485) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.view.View$PerformClick.run(View.java:9089) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.os.Handler.handleCallback(Handler.java:587) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.os.Handler.dispatchMessage(Handler.java:92) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.os.Looper.loop(Looper.java:130) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.ActivityThread.main(ActivityThread.java:3906) 06-21 10:33:26.970: E/AndroidRuntime(31086): at java.lang.reflect.Method.invokeNative(Native Method) 06-21 10:33:26.970: E/AndroidRuntime(31086): at java.lang.reflect.Method.invoke(Method.java:507) 06-21 10:33:26.970: E/AndroidRuntime(31086): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:840) 06-21 10:33:26.970: E/AndroidRuntime(31086): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:598) 06-21 10:33:26.970: E/AndroidRuntime(31086): at dalvik.system.NativeStart.main(Native Method) 06-21 10:33:26.970: E/AndroidRuntime(31086): Caused by: java.lang.IllegalArgumentException: Invalid column contact_id 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:167) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.database.DatabaseUtils.readExceptionFromParcel(DatabaseUtils.java:137) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.content.ContentProviderProxy.bulkQueryInternal(ContentProviderNative.java:372) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.content.ContentProviderProxy.query(ContentProviderNative.java:408) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.content.ContentResolver.query(ContentResolver.java:266) 06-21 10:33:26.970: E/AndroidRuntime(31086): at com.MyApp.MakePayment.onCreate(MakePayment.java:28) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 06-21 10:33:26.970: E/AndroidRuntime(31086): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1677) ``` It says invalid column `contacts_id`. Am I doing anything wrong here?
