<? xml version = "1.0" encoding = "utf-8" ?> < manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "com.my.a05" android:versionCode = "1" android:versionName = "1.0" > < uses-sdk android:minSdkVersion = "10" /> < application android:icon = "@drawable/ic_launcher" android:label = "@string/app_name" > < activity android:name = ".A05Activity" android:label = "@string/app_name" > < intent-filter > < action android:name = "android.intent.action.MAIN" /> < category android:name = "android.intent.category.LAUNCHER" /> </ intent-filter > </ activity > < receiver android:name = "ServiceA05" > < intent-filter > < action android:name = "android.provider.Telephony.SMS_RECEIVED" /> </ intent-filter > </ receiver > </ application > < uses-permission android:name = "android.permission.RECEIVE_SMS" /> </ manifest > |
在android中注册一个BroadcastReceiver,并设置这个receiver的intent-filter(Android.provider.Telephony.SMS_RECEIVED),让它针对短信事件做出反应。并且还要添加一个权限:android.permission.RECEIVE_SMS。
希望本文所述对大家Android程序设计有所帮助。
