sd卡監聽器:

package org.dreamtech.sdstate;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;public class SdcardStateReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        // 擷取事件類型        String action = intent.getAction();        if ("android.intent.action.MEDIA_MOUNTED".equals(action)) {            // sd卡掛載        } else if ("android.intent.action.MEDIA_UNMOUNTED".equals(action)) {            // sd卡卸載        }    }}

 

配置receiver

       <receiver android:name="org.dreamtech.sdstate.SdcardStateReceiver">            <intent-filter >                <action android:name="android.intent.action.MEDIA_MOUNTED"/>                <action android:name="android.intent.action."/>                                <!--約束類型叫file 因為sd裡面存的資料類型是file  -->                 <data android:scheme="file"/>            </intent-filter>        </receiver>

 

 

 

簡訊監聽器:

package org.dreamtech.smslistener;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.telephony.SmsMessage;public class SmsListenerReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        Object[] objects = (Object[]) intent.getExtras().get("pdus");        for (Object object : objects) {            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) object);            String messageBody = smsMessage.getMessageBody();            String address = smsMessage.getOriginatingAddress();            System.out.println("簡訊內容:" + messageBody + "####" + "來自" + address);        }    }}

 

 

注意配置和許可權:

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="org.dreamtech.smslistener"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="18" />    <uses-permission android:name="android.permission.RECEIVE_SMS"/>    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="org.dreamtech.smslistener.MainActivity"            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="org.dreamtech.smslistener.SmsListenerReceiver">            <intent-filter >                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>            </intent-filter>        </receiver>    </application></manifest>

 

卸載安裝監聽器:

package org.dreamtech.appstate;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;public class AppStateReceiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        String action = intent.getAction();        if ("android.intent.action.PACKAGE_INSTALL".equals(action)) {            // 應用安裝(雖然存在,但是實際並不調用)        } else if ("android.intent.action.PACKAGE_ADDED".equals(action)) {            // 應用安裝        } else if ("android.intent.action.PACKAGE_REMOVED".equals(action)) {            // 應用卸載        }    }}
