Send SMS applets

The code structure.

Now let's look at the specific code.

Send. Java

Main. xml

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> Android: Orientation = "vertical" <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "fill_parent" <br/> <textview <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: text = "Welcome to text message sender, enter the phone number "<br/> <edittext <br/> Android: Id =" @ + ID/number "<br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: hint = "Enter the phone number here" <br/> <textview <br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: text = "Welcome to text message sender, enter the text message content "<br/> <edittext <br/> Android: Id =" @ + ID/message "<br/> Android: layout_width = "fill_parent" <br/> Android: layout_height = "wrap_content" <br/> Android: minlines = "3" <br/> Android: hint = "Enter the text message here" <br/> <button <br/> Android: id = "@ + ID/button" <br/> Android: layout_width = "wrap_content" <br/> Android: layout_height = "wrap_content" <br/> Android: TEXT = "send" <br/> </linearlayout> <br/>

Androidmanifest. xml

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <manifest xmlns: Android = "http://schemas.android.com/apk/res/android" <br/> package = "cn.com. SMS. send "<br/> Android: versioncode =" 1 "<br/> Android: versionname =" 1.0 "> <br/> <uses-SDK Android: minsdkversion = "8"/> <br/> <uses-Permission Android: Name = "android. permission. send_sms "> </uses-Permission> </P> <p> <application Android: icon =" @ drawable/icon "Android: label = "@ string/app_name"> <br/> <activity Android: Name = ". send "<br/> Android: Label =" @ string/app_name "> <br/> <intent-filter> <br/> <action Android: Name =" android. intent. action. main "/> <br/> <category Android: Name =" android. intent. category. launcher "/> <br/> </intent-filter> <br/> </activity> </P> <p> </Application> <br/> </manifest>

Eventually:

Like calling a applet, you also need to enable two avds to test the function.

Bytes ----------------------------------------------------------------------------------------

Waste of words:

The main class of the text messaging application is smsmanager. Android. telephony. GSM. smsmanager should be used before Android 2.0

Android. telephony. smsmanager should be used later;

Smsmanager = smsmanager. getdefault (); gets the default information manager of the system.

Bytes ---------------------------------------------------------------------------------------

Smsmanager. sendtextmessage (destinationaddress, scaddress, text, sentintent, deliveryintent)

-- Destinationaddress: the destination phone number.
-- Scaddress: the service provider's SMS center number (for example, China Mobile's SMS center number). This parameter can be left blank for testing.
-- Text: Text message content
-- Sentintent: Send --> China Mobile failed to send --> return the sending success or failure signal --> after processing, this intent encapsulates the message sending status.

-- Deliveryintent: Send --> China Mobile sends the message successfully --> Returns whether the recipient receives the message --> subsequent processing: this intent encapsulates the status information of the message received by the other party (the supplier has successfully sent the message but the other party has not received it ).

Bytes --------------------------------------------------------------------------------------

Public static pendingintent getbroadcast (context, int requestcode, intent, int flags)
Returns a pendingintent for broadcast, similar to calling the context. sendbroadcast () function.
Requestcode is not used now
Intent is the intent used for broadcast.
Flag includes flag_one_shot, flag_no_create, flag_cancel_current, and flag_update_current, which are used to set the attributes of the newly created pendingintent once. If not, the current attribute is not created, canceled, or updated.

------------------------------------------------------------------------------

In addition, we need to declare the SMS sending permission in androidmanifest. xml.

<Uses-Permission Android: Name = "android. Permission. send_sms"/>

-------------------------------------------------------------------------------

Sometimes, when we simulate two avds to send text messages, we will find that sometimes this program cannot be used normally. The system will prompt no dns servers found and the DNS service cannot be found. This is generally because your computer is not connected to the network.

 

 

1. Send SMS:
2. Smsmanager smsmgr = smsmanager. getdefault ();
3. Smsmgr. sendtextmessage (address,Null, Message,Null,Null);
5. The text message writing interface is displayed:
6. Uri smstouri = URI. parse ("smsto: // 10086 ");
7. Intent mintent =NewIntent (Android. content. Intent. action_sendto, smstouri );
8. Startactivity (mintent );
10. Send Email:
11. Intent I =NewIntent (intent. action_send );
12. I. putextra (intent. extra_email, address );
13. I. putextra (intent. extra_subject, filename );
14. I. putextra (intent. extra_stream, Uri. parse ("file: //" + filename ));;
15. I. settype ("text/CSV ");
16. Startactivity (intent. createchooser (I, "email file "));
