Android中实现基本的短信拦截功能的代码示例
要点
1.在Manifest.xml里加"接收"SMS的权限
<uses-permissionAndroid:name="android.permission.RECEIVE_SMS"></uses-permission>
2.在Manifest.xml里注册一个receive
<!--注册Receiver,并且设置优先级--> <receiverandroid:name=".AutoSMS"android:exported="false"> <intent-filterandroid:priority="1000"> <actionandroid:name="android.provider.Telephony.SMS_RECEIVED"/> </intent-filter> </receiver>
3.定义一个短信接收类,并且重写onReceive
//继承BroadcastReceiver
publicclassAutoSMSextendsBroadcastReceiver
{
privateStringTAG="AutSMS";
//广播消息类型
publicstaticfinalStringSMS_RECEIVED_ACTION="android.provider.Telephony.SMS_RECEIVED";
//覆盖onReceive方法
@Override
publicvoidonReceive(Contextcontext,Intentintent)
{
.....
