Android 來電、短信、掛斷、接通廣播事件完整指南與權限配置

核心廣播與監聽

實現要點

1. 來電監聽 (Service + PhoneStateListener)

public class CallListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String number) {
        switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                // 來電，number 為來電號碼，啟動閃光服務
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                // 接通
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                // 掛斷/空閒
                break;
        }
    }
}
// 在 Service onCreate 中註冊
TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
tm.listen(new CallListener(), PhoneStateListener.LISTEN_CALL_STATE);

2. 去電攔截 (BroadcastReceiver)

<receiver android:name=".OutgoingCallReceiver">
    <intent-filter android:priority="100">
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
    </intent-filter>
</receiver>
// onReceive 中 getResultData() 獲取號碼，setResultData(newNumber) 修改

3. 短信接收 (BroadcastReceiver, Android 4.4+ 需默認短信應用)

<receiver android:name=".SmsReceiver" android:exported="true" android:permission="android.permission.BROADCAST_SMS">
    <intent-filter android:priority="999">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>
// onReceive 解析 pdus 獲取 SmsMessage

權限聲明 (AndroidManifest.xml)

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

版本適配提示

• Android 6.0+ 運行時權限請求 (requestPermissions)。
• Android 8.0+ 隱式廣播限制，ACTION_PHONE_STATE_CHANGED 需動態註冊或用 PhoneStateListener。
• Android 10+ 後台啟動 Activity 限制，閃光服務需前台服務 (startForeground)。
