Question

大家好，有没有办法检查Android设备是否有SIM模块。我已经检查过设备是否有SIM卡。使用此代码

public void SimCheck() {
    TelephonyManager telMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    int simState = telMgr.getSimState();
    switch (simState) {
    case TelephonyManager.SIM_STATE_ABSENT:
        Log.d("SimCheck", "No sim Availble");
        Toast.makeText(getApplicationContext(), "No Sim Availble ",
                Toast.LENGTH_LONG).show();
        break;
    case TelephonyManager.SIM_STATE_READY:
        Log.d("SimCheck", "Sim Is availble");
        Toast.makeText(getApplicationContext(), "Sim Is Availble",
                Toast.LENGTH_LONG).show();
        break;

    case TelephonyManager.SIM_STATE_UNKNOWN:
        Log.d("SimCheck", "Network Locked");
        Toast.makeText(getApplicationContext(),
                "Sim state unknown or network not Availble ",
                Toast.LENGTH_LONG).show();
        break;

    }

}

现在我想检查设备中是否有Sim模块（因为平板电脑中没有SIM卡选项）。需要帮忙。提前致谢

Answer 1

你可以添加

<uses-feature android:name="android.hardware.telephony"
              android:required="true"/>

如果您希望您的应用需要SIM模块，请

到您的清单。

Answer 2

尝试：FEATURE_TELEPHONY

Added in API level 7 Feature for getSystemAvailableFeatures() and hasSystemFeature(String): The device has a telephony radio with data communication support.

PackageManager pm = this.getPackageManager();
boolean hasTelephony=pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY);

注意：“这对于检测短信功能存在问题。如果设备安装了Google语音，即使它没有任何电话功能，它仍然可以发送短信。所以这种方法可能会给你带来漏报。” / p>
