java.lang.IllegalStateException：进程478超出游标配额100，将其终止

Question

我只想加载我手机的所有联系人，下面是源代码。我也关闭了光标，我不知道为什么会发生这种错误，有人可以告诉我导致此错误的原因以及解决方法。

Cursor cursor = null;
try {
    Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
    cursor = mActivity.getContentResolver().query(uri,new String[] {ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.LOOKUP_KEY }, null, null, null);

    while (cursor != null && cursor.moveToNext()) {
        String number = cursor.getString(0);
        String name = cursor.getString(1);
        String id = cursor.getString(2);
        String key = cursor.getString(3);

        number = Utils.trimTelNum(number);

        LogUtil.i(TAG, "contacts number=" + number + ",name=" + name);

            if (number == null || name == null) {
                Log.e(TAG, "contacts name or number is null,continue");
                continue;
            }
            CalllogBean bean = new CalllogBean();
            bean.setContactId(id);
            bean.setNumber(number);
            bean.setContactName(name);
            bean.setLookupKey(key);
            contactsMap.put(number, bean);
        }

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        // close the cursor
        if (cursor != null) {
            cursor.close();
            cursor = null;
        }
    }
