<uses-SDK Android:minsdkversion= "14"android:targetsdkversion= "/>"<uses-permission android:name= "Android.permission.SEND_SMS"/><Application Android:allowbackup= "true"Android:icon= "@drawable/ic_launcher"Android:label= "@string/app_name"Android:theme= "@style/apptheme" > <Activity Android:name=". Mainactivity "Android:label= "@string/app_name" > <intent-filter> <action android:name= "Android.intent.action.MA In "/> <category android:name=" Android.intent.category.LAUNCHER "/> </intent-filter&        Gt </activity> </application>
