Creating an SMS app

+ * + *

Only the default SMS app (selected by the user in system settings) is able to write to the + * SMS Provider (the tables defined within the {@code Telephony} class) and only the default SMS + * app receives the {@link android.provider.Telephony.Sms.Intents#SMS_DELIVER_ACTION} broadcast + * when the user receives an SMS or the {@link + * android.provider.Telephony.Sms.Intents#WAP_PUSH_DELIVER_ACTION} broadcast when the user + * receives an MMS.

+ * + *

Any app that wants to behave as the user's default SMS app must handle the following intents: + *

    + *
  • In a broadcast receiver, include an intent filter for {@link Sms.Intents#SMS_DELIVER_ACTION} + * ("android.provider.Telephony.SMS_DELIVER"). The broadcast receiver must also + * require the {@link android.Manifest.permission#BROADCAST_SMS} permission. + *

    This allows your app to directly receive incoming SMS messages.

    • + *
  • In a broadcast receiver, include an intent filter for {@link + * Sms.Intents#WAP_PUSH_DELIVER_ACTION}} ({@code "android.provider.Telephony.WAP_PUSH_DELIVER"}) + * with the MIME type "application/vnd.wap.mms-message". + * The broadcast receiver must also require the {@link + * android.Manifest.permission#BROADCAST_WAP_PUSH} permission. + *

    This allows your app to directly receive incoming MMS messages.

    • + *
  • In your activity that delivers new messages, include an intent filter for + * {@link android.content.Intent#ACTION_SENDTO} ("android.intent.action.SENDTO" + * ) with schemas, sms:, smsto:, mms:, and + * mmsto:. + *

    This allows your app to receive intents from other apps that want to deliver a + * message.

    • + *
  • In a service, include an intent filter for {@link + * android.telephony.TelephonyManager#ACTION_RESPOND_VIA_MESSAGE} + * ("android.intent.action.RESPOND_VIA_MESSAGE") with schemas, + * sms:, smsto:, mms:, and mmsto:. + * This service must also require the {@link + * android.Manifest.permission#SEND_RESPOND_VIA_MESSAGE} permission. + *

    This allows users to respond to incoming phone calls with an immediate text message + * using your app.

    • + *
+ * + *

Other apps that are not selected as the default SMS app can only read the SMS + * Provider, but may also be notified when a new SMS arrives by listening for the {@link + * Sms.Intents#SMS_RECEIVED_ACTION} + * broadcast, which is a non-abortable broadcast that may be delivered to multiple apps. This + * broadcast is intended for apps that—while not selected as the default SMS app—need to + * read special incoming messages such as to perform phone number verification.

+ * + *

    + *
  • opt-in informational broadcasts, e.g. news, weather, stock quotes, sports scores
    • + *
  • cell information messages, broadcast on channel 50, indicating the current cell name for + * roaming purposes (required to display on the idle screen in Brazil)
    • + *
  • emergency broadcasts for the Japanese Earthquake and Tsunami Warning System (ETWS)
    • + *
  • emergency broadcasts for the American Commercial Mobile Alert Service (CMAS)
    • + *
+ * + *

There are also four different CB message formats: GSM, ETWS Primary Notification (GSM only), + * UMTS, and CDMA. Some fields are only applicable for some message formats. Other fields were + * unified under a common name, avoiding some names, such as "Message Identifier", that refer to + * two completely different concepts in 3GPP and CDMA. + * + *

The GSM/UMTS Message Identifier field is available via {@link #getServiceCategory}, the name + * of the equivalent field in CDMA. In both cases the service category is a 16-bit value, but 3GPP + * and 3GPP2 have completely different meanings for the respective values. For ETWS and CMAS, the + * application should + * + *

The CDMA Message Identifier field is available via {@link #getSerialNumber}, which is used + * to detect the receipt of a duplicate message to be discarded. In CDMA, the message ID is + * unique to the current PLMN. In GSM/UMTS, there is a 16-bit serial number containing a 2-bit + * Geographical Scope field which indicates whether the 10-bit message code and 4-bit update number + * are considered unique to the PLMN, to the current cell, or to the current Location Area (or + * Service Area in UMTS). The relevant values are concatenated into a single String which will be + * unique if the messages are not duplicates. + * + *

The SMS dispatcher does not detect duplicate messages. However, it does concatenate the + * pages of a GSM multi-page cell broadcast into a single SmsCbMessage object. + * + *

Interested applications with {@code RECEIVE_SMS_PERMISSION} can register to receive + * {@code SMS_CB_RECEIVED_ACTION} broadcast intents for incoming non-emergency broadcasts. + * Only system applications such as the CellBroadcastReceiver may receive notifications for + * emergency broadcasts (ETWS and CMAS).
