android - Modify or update contacts using intent programmatically

Question

I would like to intent to the android contact window to update or modify a user contact details. The code below works fine, however, it does not pass the correct phone number to the android contact editor window.

This is my code

 private void modifyContact() {
         phonenumber="0711236763";

    mSelectedContactUri=Uri.parse(phonenumber);

    mCursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);


    if (mCursor != null && mCursor.moveToFirst()) {
        mLookupKeyIndex = mCursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY);
        mCurrentLookupKey = mCursor.getString(mLookupKeyIndex);
        mIdIndex = mCursor.getColumnIndex(ContactsContract.Contacts._ID);
        mCurrentId = mCursor.getLong(mIdIndex);
    }

    mSelectedContactUri = ContactsContract.Contacts.getLookupUri(mCurrentId, mCurrentLookupKey);
    Intent editIntent = new Intent(Intent.ACTION_EDIT);

    editIntent.setDataAndType(mSelectedContactUri, ContactsContract.Contacts.CONTENT_ITEM_TYPE);
    editIntent.putExtra("finishActivityOnSaveCompleted", true);

    startActivity(editIntent);

    }

The variable phonenumber is the phone number for which i would like to modify or update.

Answer 1

Make sure the Cursor is initialized correctly before accessing data from it." it works in my code.

1.Try to position cursor by moveToFirst before reading data from it.

2.check for null-> if (c != null && c.moveToFirst()) {}

3.check for count-> (c != null && c.getCount() >0 && c.moveToFirst()){}
