如何在Android上获取用户的手机号码？

问题描述

我已经实现了以下广泛使用的代码，但我遇到了安全异常。

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
    SubscriptionManager sManager = (SubscriptionManager) context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
    SubscriptionInfo infoSim1 = sManager.getActiveSubscriptionInfoForSimslotIndex(0);
    SubscriptionInfo infoSim2 = sManager.getActiveSubscriptionInfoForSimslotIndex(1);
    return infoSim1 != null || infoSim2 != null;
} else {
    TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return telephonyManager.getSimserialNumber() != null;
}

错误日志如下

解决方法

    TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

在清单中添加一行

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
