Czy można blokować wychodzące wiadomości SMS?

Question

Oto kod, który używam,

public class MyCallControllerActivity extends Activity 
{ 
    static int Count; 
/** Called when the activity is first created. */ 
CheckBox blockAll_cb;//,blockcontacts_cb; 
BroadcastReceiver CallBlocker; 

TelephonyManager telephonyManager; 


@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 
initviews(); 

CallBlocker =new BroadcastReceiver() 
{ 


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


     if (bundle != null) 
     { 
      // do you manipulation on String then if you can abort. 


     } 

     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]); 
     } 
     if("+919739036754".equalsIgnoreCase(smsMessage[0].getOriginatingAddress())) 
     { 
      //abortBroadcast(); 
      String Body=smsMessage[0].getMessageBody(); 
      if (Body.startsWith("START")) 
      { 
       Toast toast6 = Toast.makeText(context,"There is START ", Toast.LENGTH_LONG);toast6.show(); 

      } 
      else 
      { 
       setResultData(null); 
       setResultCode(0); 
       abortBroadcast(); 
      } 
     } 
     else 
     { 


     } 
     // show first message 
     Toast toast1= Toast.makeText(context,"Sent SMS: " + smsMessage[0].getOriginatingAddress()+ "\nBody: "+smsMessage[0].getMessageBody(), Toast.LENGTH_LONG); 
     toast1.show(); 

} 
};//BroadcastReceiver 
IntentFilter filter= new IntentFilter("android.provider.Telephony.SMS_SENT"); 
registerReceiver(CallBlocker, filter); 




} 



public void initviews() 
{ 
blockAll_cb=(CheckBox)findViewById(R.id.cbBlockAll); 

} 
@Override 
protected void onDestroy() { 
// TODO Auto-generated method stub 
super.onDestroy(); 
if (CallBlocker != null) 
{ 
unregisterReceiver(CallBlocker); 
CallBlocker = null; 
} 

Oto Manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.block" 
    android:versionCode="1"

Answer 1

Nie można zablokować SMS wychodzący z aplikacji domyślnej wiadomości, ponieważ nie ma Broadcast dla wychodzących wiadomości tekstowych .

Pokaże to proste wyszukiwanie Google. https://www.google.com/search?q=block+outgoing+sms+android+programmatically

I to działało, ale tylko z korzeniami urządzenia za zgodą MODIFY_PHONE_STATE

public class OutgoingSMSReceiver extends Service 
{ 

private static final String CONTENT_SMS = "content://sms/"; 
static String messageId = ""; 

private class MyContentObserver extends ContentObserver 
{ 

    Context context; 
    private SharedPreferences prefs; 
    private String phoneNumberBlocked; 

    public MyContentObserver(Context context) { 
     super(null); 
     this.context = context; 
    } 

    @Override 
    public void onChange(boolean selfChange) 
    { 
     super.onChange(selfChange); 

     prefs = context.getSharedPreferences("com.example.testcall", Context.MODE_PRIVATE); 
     phoneNumberBlocked = prefs.getString("numero", ""); 

     Uri uriSMSURI = Uri.parse(CONTENT_SMS); 
     Cursor cur = context.getContentResolver().query(uriSMSURI, null, null, null, null); 

     if (cur.moveToNext()) 
     { 
      String message_id = cur.getString(cur.getColumnIndex("_id")); 
      String type = cur.getString(cur.getColumnIndex("type")); 
      String numeroTelephone=cur.getString(cur.getColumnIndex("address")).trim(); 

      if (numeroTelephone.equals(phoneNumberBlocked)) 
      { 
       if (cur.getString(cur.getColumnIndex("type")).equals("6")) 
       {      
        ContentValues values = new ContentValues(); 
        values.put("type", "5"); 
        context.getContentResolver().update(uriSMSURI,values,"_id= "+message_id,null);       
       } 
       else if(cur.getString(cur.getColumnIndex("type")).equals("5")) 
       {       context.getContentResolver().delete(uriSMSURI,"_id=?",new String[] { message_id});      
       } 
      } 
     } 
    } 

    @Override 
    public boolean deliverSelfNotifications() 
    { 
     return false; 
    } 
} 

@Override 
public void onCreate() 
{ 
    MyContentObserver contentObserver = new MyContentObserver(getApplicationContext()); 
    ContentResolver contentResolver = getBaseContext().getContentResolver(); 
    contentResolver.registerContentObserver(Uri.parse(CONTENT_SMS), true, contentObserver); 

}
