[android篇]android 4.4 短信适配

andorid 4.4(KITKAT)对系统很多方面做了改动，在目前的项目中，对短信有直接的影响。我们看一下下面这段文档说明：

Advice for SMS backup & restore apps

Because the ability to write to the SMSProvider is restricted to the app the user selects as the default SMS app, anyexisting app designed purely to backup and restore SMS messages will currentlybe unable
to restore SMS messages on Android 4.4. An app that backs up andrestores SMS messages must also be set as the default SMS app so that it canwrite messages in the SMS Provider.

因此，我们需要对4.4做相应的适配

• In a broadcast receiver, include an intent filter for SMS_DELIVER_ACTION("android.provider.Telephony.SMS_DELIVER"). The broadcast receiver must also require the BROADCAST_SMS permission.

  This allows your app to directly receive incoming SMS messages.

public class SmsReceiver extends BroadcastReceiver {

	@Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();

        if (extras == null) {
            return;
        }

        Object[] smsExtras = (Object[]) extras.get("pdus");
        if (smsExtras == null || smsExtras.length == 0) {
            return;
        }

        ContentResolver contentResolver = context.getContentResolver();

		for (Object smsExtra : smsExtras) {
			try {
				byte[] smsBytes = (byte[]) smsExtra;
				SmsMessage smsMessage = SmsMessage.createFromPdu(smsBytes);

				ContentValues values = new ContentValues();
				values.put(Sms.ADDRESS, smsMessage.getOriginatingAddress());
				values.put(Sms.BODY, smsMessage.getMessageBody());
				values.put(Sms.DATE, smsMessage.getTimestampMillis());
				values.put(Sms.READ, 0);
				values.put(Sms.TYPE, Sms.MESSAGE_TYPE_INBOX);

				contentResolver.insert(Uri.parse("content://sms"), values);
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
    }

}

• In a broadcast receiver, include an intent filter for WAP_PUSH_DELIVER_ACTION("android.provider.Telephony.WAP_PUSH_DELIVER") with the MIME type "application/vnd.wap.mms-message".
  The broadcast receiver must also require the BROADCAST_WAP_PUSH permission.

  This allows your app to directly receive incoming MMS messages.

public class MmsReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO
	}

}

MMS日常生活中用的不多，没有做相应的处理

• In your activity that delivers new messages, include an intent filter for 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.

public class ComposeSmsActivity extends Activity {

}

• In a service, include an intent filter for ACTION_RESPONSE_VIA_MESSAGE("android.intent.action.RESPOND_VIA_MESSAGE")
  with schemas, sms:, smsto:, mms:, and mmsto:. This service must also require the SEND_RESPOND_VIA_MESSAGE permission.

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

public class HeadlessSmsSendService extends IntentService {

	public HeadlessSmsSendService() {
        super(HeadlessSmsSendService.class.getName());

        setIntentRedelivery(true);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        String action = intent.getAction();
        if (!TelephonyManager.ACTION_RESPOND_VIA_MESSAGE.equals(action)) {
            return;
        }

        Bundle extras = intent.getExtras();

        if (extras == null) {
            return;
        }

        String message = extras.getString(Intent.EXTRA_TEXT);
        Uri intentUri = intent.getData();
        String recipients = getRecipients(intentUri);

        if (TextUtils.isEmpty(recipients)) {
            return;
        }

        if (TextUtils.isEmpty(message)) {
            return;
        }

        String[] destinations = TextUtils.split(recipients, ";");

        sendAndStoreTextMessage(getContentResolver(), destinations, message);
    }

    /**
     * get quick response recipients from URI
     */
    private String getRecipients(Uri uri) {
        String base = uri.getSchemeSpecificPart();
        int pos = base.indexOf('?');
        return (pos == -1) ? base : base.substring(0, pos);
    }

    /**
     * Send text message to recipients and store the message to SMS Content Provider
     *
     * @param contentResolver ContentResolver
     * @param destinations recipients of message
     * @param message message
     */
    private void sendAndStoreTextMessage(ContentResolver contentResolver, String[] destinations, String message) {
        SmsManager smsManager = SmsManager.getDefault();
        for (String destination : destinations) {
        	try{
	            smsManager.sendTextMessage(destination, null, message, null, null);
	            ContentValues values = new ContentValues();
	            values.put(Sms.ADDRESS, destination);
	            values.put(Sms.BODY, message);
				values.put(Sms.DATE, System.currentTimeMillis());
				values.put(Sms.READ, 0);
				values.put(Sms.TYPE, Sms.MESSAGE_TYPE_SENT);

	            contentResolver.insert(Uri.parse("content://sms"), values);
        	}catch(Exception e){
        		e.printStackTrace();
        	}
        }
    }

}
