Android API Development SMS SMS service processing and obtaining contact person's method _android

This article describes the development of the Android API SMS SMS service processing and access to the method of contact person. Share to everyone for your reference, specific as follows:

The Android API supports the development of applications that can send and receive SMS messages. The Android emulator used in our development process is not yet supported for SMS, but it can receive SMS. Now let's explore Android's support for SMS, and we'll build a small application that listens to SMS messages received on a mobile device (or emulator) and displays it.
Let's define a intent receiver to handle SMS receive events:

Package com.wissen.sms.receiver;
public class Smsreceiver extends Broadcastreceiver {
  @Override
  the public void onreceive (context context, Intent Intent) {
    //TODO
  }
}
package com.wissen.sms.receiver;
public class Smsreceiver extends Broadcastreceiver {
@Override
the public void onreceive (context context, Intent Intent) {
//TODO
}
}

We need to configure this intent receiver so that it can get SMS receive events, Android.provider.Telephony.SMS_RECEIVED This event status indicates that SMS has been received. We can configure the following in Androidmanifest.xml:

<receiver android:name= ". Receiver. Smsreceiver "android:enabled=" true ">
<intent-filter>
<action android:name=" Android.provider.Telephony.SMS_RECEIVED "/>
</intent-filter>
</receiver>
< Receiver Android:name= ". Receiver. Smsreceiver "android:enabled=" true ">
<intent-filter>
<action android:name=" Android.provider.Telephony.SMS_RECEIVED "/>
</intent-filter>
</receiver>

In order for our applications to receive SMS, we have to specify the permissions, which can be configured in Androidmanifest.xml as follows:

<uses-permission android:name= "Android.permission.RECEIVE_SMS" ></uses-permission>
< Uses-permission android:name= "Android.permission.RECEIVE_SMS" ></uses-permission>

Now, our intent receiver can be invoked when the Android device receives SMS, and the rest is to get and display the text of the SMS message received:

public void OnReceive (context context, Intent Intent) {Bundle Bundle = Intent.getextras ();
    Object messages[] = (object[]) bundle.get ("PDUs");
    Smsmessage smsmessage[] = new Smsmessage[messages.length];
    for (int n = 0; n < messages.length n++) {Smsmessage[n] = SMSMESSAGE.CREATEFROMPDU ((byte[)) messages[n]);        }//Show the Toast Toast = Toast.maketext (Context, "Received SMS:" + smsmessage[0].getmessagebody (),
   Toast.length_long);
Toast.show ();
public void OnReceive (context context, Intent Intent) {Bundle Bundle = Intent.getextras ();
Object messages[] = (object[]) bundle.get ("PDUs");
Smsmessage smsmessage[] = new Smsmessage[messages.length]; for (int n = 0; n < messages.length n++) {Smsmessage[n] = SMSMESSAGE.CREATEFROMPDU ((byte[)) messages[n]);//Show F Irst message Toast Toast = Toast.maketext (Context, Received SMS: "+ smsmessage[0].getmessagebody (), toast.length_
LONG);
Toast.show ();

 }

The SMS received by the Android device is in PDU form (Protocol description unit). Android.telephony.gsm.SmsMessage This class can store information about SMS, we can also create a new Smsmessage instance from the received PDU, Toast Interface component can display the received SMS message text in the form of system notification.

To run the program:

Now let's run the application in the emulator and send SMS messages to the emulator. We can send SMS messages to the emulator in the Ddms view (Dalvik Debug Monitor Service) provided by the Eclipse's Android plug-in (in ' Emulator Control Panel; You also need to specify a phone number, but it can be arbitrary.

How to issue broadcast intent:

public static final String music_action= "Com.mythlink.MUSIC";
Intent intent=new Intent ();
Intent.setaction (music_action);
Intent.putextra ("Music_path", Songpath);
This.sendbroadcast (intent);
public static final String music_action= "Com.mythlink.MUSIC";
Intent intent=new Intent ();
Intent.setaction (music_action);
Intent.putextra ("Music_path", Songpath);
This.sendbroadcast (Intent);

Need to write another broadcast receiver:

public class Musicreceiver extends Broadcastreceiver {
 @Override
 the public void onreceive (context context, Intent Intent) {
 Bundle bundle=intent.getextras ();
 String music_path=bundle.getstring ("Music_path");
 Toast Toast=toast.maketext (Context, "Playing music:" +music_path, Toast.length_long);
 Toast.show ();
 }
The public class Musicreceiver extends Broadcastreceiver {
@Override
the public void onreceive Intent Intent) {
Bundle bundle=intent.getextras ();
String music_path=bundle.getstring ("Music_path");
Toast Toast=toast.maketext (Context, "Playing music:" +music_path, Toast.length_long);
Toast.show ();
}

Get contact information:

public class Contactslist extends Listactivity {private ListAdapter madapter;
 @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
 Cursor c=this.getcontentresolver (). query (Contacts.People.CONTENT_URI, NULL, NULL, NULL, NULL);
 This.startmanagingcursor (c);
 String[] Columns=new String[]{contacts.people.name}; Int[] names=new int[]{r.id.song};////////////////madapter = new Simplecursoradapter (this, R.layout.song_item, C,
 columns, names);
 This.setlistadapter (Madapter); @Override protected void Onlistitemclick (ListView l, View v, int position, long id) {Super.onlistitemclick (L, V, POS
 Ition, id);
 Intent i=new Intent (Intent.action_call);
   Cursor C = (Cursor) madapter.getitem (position);
   Long Phoneid = C.getlong (C.getcolumnindex (Contacts.People.PRIMARY_PHONE_ID));
   I.setdata (Contenturis.withappendedid (Contacts.Phones.CONTENT_URI, Phoneid));
 This.startactivity (i); } public class Contactslist extends Listactivity {PrivaTe ListAdapter madapter;
@Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
Cursor c=this.getcontentresolver (). query (Contacts.People.CONTENT_URI, NULL, NULL, NULL, NULL);
This.startmanagingcursor (c);
String[] Columns=new String[]{contacts.people.name}; Int[] names=new int[]{r.id.song};////////////////madapter = new Simplecursoradapter (this, R.layout.song_item, C,
columns, names);
This.setlistadapter (Madapter); @Override protected void Onlistitemclick (ListView l, View v, int position, long id) {Super.onlistitemclick (L, V, Positi
on, id);
Intent i=new Intent (Intent.action_call);
Cursor C = (Cursor) madapter.getitem (position);
Long Phoneid = C.getlong (C.getcolumnindex (Contacts.People.PRIMARY_PHONE_ID));
I.setdata (Contenturis.withappendedid (Contacts.Phones.CONTENT_URI, Phoneid));
This.startactivity (i);

 }
}

Add in Androidmanifest.xml:

<uses-permission android:name= "Android.permission.READ_CONTACTS"/>
<activity android:name= ". Contactslist "
     android:label=" @string/app_name ">
  <intent-filter>
    <action android:name=" Android.intent.action.MAIN "/>
    <category android:name= android.intent.category.LAUNCHER"/>
  < /intent-filter>
</activity>
