Android: How to check if an incoming SMS number exists in a contact phone in BroadcastReceiver, and the block number does not exist

Question

I want to be when there are incoming sms, the number of which is not in the contact, then the text in the block, of course, checking if there is any number, is not in the phone book. I have a code verification number, but a time error, do I move the code in the BroadcastReceiver? class, and how to call the contactExists method on onReceive?

public boolean contactExists(Context context, String number, ContentResolver contentResolver) { Cursor phones = contentResolver.query(ContactsContract.CommonDataKinds.Phone. CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC"); while (phones.moveToNext()){ String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); if(PhoneNumberUtils.compare(number, phoneNumber)){ return true; } } return false; } 

I use AsyncTask, but I'm confused by what to call the contactExists method, and how do I enter a number in contactExists to find out what the number of existing

 public class SmsReceiver extends BroadcastReceiver { public static int MSG_TPE = 0; private String number; @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if (action.equals(AppConstants.SMS_RECEIVED_ACTION)) { Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String message = ""; String date = AppUtils.getDate(); String time = AppUtils.getTime(); String status = AppUtils.getStatus(); if (bundle != null) { Object[] pdus = (Object[]) bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for (int i = 0; i < msgs.length; i++) { msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); number = msgs[i].getOriginatingAddress(); message += msgs[i].getMessageBody().toString(); message += "\n"; } if (SettingsPreferences.isBlockAllSms(context)) { this.abortBroadcast(); CallMessageItem item = new CallMessageItem(); item.setDate(date); item.setMessage(message); item.setNumber(number); item.setTime(time); item.setStatus(status); item.setType(AppConstants.TYPE_MESSAGE); CMBDataProvider.addCallMessage(context, item); if (SettingsPreferences.isNotificationShow(context)) { AppUtils.generateNotification( context, context.getResources().getString( R.string.block_sms_message), false); } } else if (SettingsPreferences.isBlockPrivateSms(context)) { ArrayList<BlockItem> block_number = CMBDataProvider .getBlackList(context); if (!TextUtils.isEmpty(message) && !TextUtils.isEmpty(number) && block_number != null && block_number.size() > 0) { message = message.trim(); for (int i = 0; i < block_number.size(); i++) { if (number .contains(block_number.get(i).getNumber())) { this.abortBroadcast(); CallMessageItem item = new CallMessageItem(); item.setDate(date); item.setMessage(message); item.setNumber(number); item.setTime(time); item.setType(AppConstants.TYPE_MESSAGE); CMBDataProvider.addCallMessage(context, item); if (SettingsPreferences .isNotificationShow(context)) { AppUtils.generateNotification( context, context.getResources().getString( R.string.block_sms_message), false); } break; } } } } } } } private class Contactexixt extends AsyncTask<String, Integer, Double> { @Override protected Double doInBackground(String... params) { // TODO Auto-generated method stub contactExists(params[0]); return null; } public boolean contactExists(Context context, String number){ Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number)); String[] mPhoneNumberProjection = { ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.NUMBER, ContactsContract.PhoneLookup.DISPLAY_NAME }; Cursor cur = context.getContentResolver().query(lookupUri,mPhoneNumberProjection, null, null, null); try { // Add your data } catch (ClientProtocolException e) { // TODO Auto-generated catch block } catch (IOException e) { // TODO Auto-generated catch block } } } }

Do not request a content provider in the main thread, start a new thread, or use AsyncTask.

 private class Checkcontact extends AsyncTask<String, Void, Boolean> { private Context context; public Checkcontact(Context context) { // TODO Auto-generated constructor stub this.context = context; } @Override protected Boolean doInBackground(String... strings) { try { return contactExists(context, strings[0]); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return false; } // The argument result is return by method doInBackground @Override protected void onPostExecute(Boolean result) { // TODO Auto-generated method stub super.onPostExecute(result); // You can handle the result here } public boolean contactExists(Context context, String number) throws Exception { Uri lookupUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number)); String[] mPhoneNumberProjection = { ContactsContract.PhoneLookup._ID, ContactsContract.PhoneLookup.NUMBER, ContactsContract.PhoneLookup.DISPLAY_NAME }; Cursor cur = context.getContentResolver().query(lookupUri, mPhoneNumberProjection, null, null, null); try { if (cur.moveToFirst()) { // if contact are in contact list it will return true return true; } } finally { if (cur != null) cur.close(); } // if contact are not match that means contact are not added return false; } } 

Run the task:

 new Checkcontact(context).execute("123456789");
