在 Android 上阻止传入/传出短信

Question

有谁知道通过代码阻止传入/传出短信的可靠方法？如果收到实际的短信也没关系，但我想阻止收到该短信的任何通知。此外，不应允许用户发送（或者最好是键入）SMS 消息。这可能吗？

谢谢

Answer 1

您无法阻止外发短信。

这是我用来阻止传入文本的方法。

从清单中删除的主要内容是服务块、接收器块和权限。

Answer 2

关于阻止传入短信。您可以以高优先级注册广播接收器，以便在调用系统应用程序之前调用您的代码。与广播接收器相比，您可以中止广播，其他应用程序将看不到它。

在清单中注册接收器：

<receiver android:name=".SmsReceiver">
    <intent-filter android:priority="2147483647">
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

然后在广播接收器中注册：

@Override
public void onReceive(Context context, Intent intent) {
    abortBroadcast();
}
