android拦截短信并屏蔽系统的Notification

拦截短信有几个关键点：

1.android接收短信时是以广播的方式

2.程序只要在自己的Manifest.xml里加有"接收"SMS的权限

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

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

3.要写个广播接收类

publicclasssmsreceiveandmaskextendsBroadcastReceiver{
privateStringTAG="smsreceiveandmask";
@Override
publicvoidonReceive(Contextcontext,Intentintent){

}

public class smsreceiveandmask extends BroadcastReceiver {private String TAG = "smsreceiveandmask";@Overridepublic void onReceive(Context context, Intent intent) {}

4.Manifest.xml的receiver标签里要加入intent-filter ,action为

<actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/>

<action android:name="android.provider.Telephony.SMS_RECEIVED" />

5.重要的是要在这个intent-filter上加上priority优先级，以使自己接收到SMS优先于系统或其它软件

<receiverandroid:name=".smsreceiveandmask">
<intent-filterandroid:priority="1000">
<actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>

<receiver android:name=".smsreceiveandmask" ><intent-filter android:priority="1000"> <action android:name="android.provider.Telephony.SMS_RECEIVED" /></intent-filter></receiver>

6.当自己的程序接收到要屏蔽的SMS后，用 this.abortBroadcast();来结束广播的继续发给别的程序，这样系统就不会收到短信广播了，Notification也不会有提示了

//第三步:取消
if(flags_filter){
this.abortBroadcast();
}

// 第三步:取消if (flags_filter) {this.abortBroadcast();}

源码如下：

Manifest.xml

<?xmlversion="1.0"encoding="utf-8"?>
<manifestxmlns:android="http://schemas.android.com/apk/res/android"
package="com.hwttnet.test.smsreceiveandmask"android:versionCode="1"

</intent-filter>
</receiver>
</application>
</manifest>

BroadcastReceiver类：

packagecom.hwttnet.test.smsreceiveandmask;
importandroid.app.Activity;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.telephony.SmsMessage;
importandroid.util.Log;
publicclasssmsreceiveandmaskextendsBroadcastReceiver{
privateStringTAG="smsreceiveandmask";
@Override
publicvoidonReceive(Contextcontext,Intentintent){
Log.v(TAG,">>>>>>>onReceivestart");
//第一步、获取短信的内容和发件人
StringBuilderbody=newStringBuilder();//短信内容
StringBuildernumber=newStringBuilder();//短信发件人
Bundlebundle=intent.getExtras();
if(bundle!=null){
Object[]_pdus=(Object[])bundle.get("pdus");
SmsMessage[]message=newSmsMessage[_pdus.length];
for(inti=0;i<_pdus.length;i++){
message[i]=SmsMessage.createFromPdu((byte[])_pdus[i]);
}
for(SmsMessagecurrentMessage:message){
body.append(currentMessage.getDisplayMessageBody());
number.append(currentMessage.getDisplayOriginatingAddress());
}
StringsmsBody=body.toString();
StringsmsNumber=number.toString();
if(smsNumber.contains("+86")){
smsNumber=smsNumber.substring(3);
}
//第二步:确认该短信内容是否满足过滤条件
booleanflags_filter=false;
if(smsNumber.equals("10086")){//屏蔽10086发来的短信
flags_filter=true;
Log.v(TAG,"sms_number.equals(10086)");
}
//第三步:取消
if(flags_filter){
this.abortBroadcast();
}
}
Log.v(TAG,">>>>>>>onReceiveend");
}
}
