我从sdk级别android.os.Build.VERSION_CODES.LOLLIPOP_MR1知道我们将subscriptionInfoList作为subscriptionManager.getActiveSubscriptionInfoList();
并以此识别所有支持的SIM卡信息。
我需要在android较低版本中获得同样的效果。有人可以帮助我吗?
最佳答案
幸运的是,有几种本机解决方案。
对于API> = 17:
TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
// Get information about all radio modules on device board
// and check what you need by calling #getCellIdentity.
final List<CellInfo> allCellInfo = manager.getAllCellInfo();
for (CellInfo cellInfo : allCellInfo) {
if (cellInfo instanceof CellInfoGsm) {
CellIdentityGsm cellIdentity = ((CellInfoGsm) cellInfo).getCellIdentity();
//TODO Use cellIdentity to check MCC/MNC code, for instance.
} else if (cellInfo instanceof CellInfoWcdma) {
CellIdentityWcdma cellIdentity = ((CellInfoWcdma) cellInfo).getCellIdentity();
} else if (cellInfo instanceof CellInfoLte) {
CellIdentityLte cellIdentity = ((CellInfoLte) cellInfo).getCellIdentity();
} else if (cellInfo instanceof CellInfoCdma) {
CellIdentityCdma cellIdentity = ((CellInfoCdma) cellInfo).getCellIdentity();
}
}
在AndroidManifest中添加权限:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
</manifest>
要获取网络运营商,您可以检查mcc和mnc代码:
https://en.wikipedia.org/wiki/Mobile_country_code(一般信息)。
https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list-(相当完整的最新操作员列表)。
对于最新的设备,您可以使用最新的API。
对于API> = 22:
final SubscriptionManager subscriptionManager = SubscriptionManager.from(context);
final List<SubscriptionInfo> activeSubscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : activeSubscriptionInfoList) {
final CharSequence carrierName = subscriptionInfo.getCarrierName();
final CharSequence displayName = subscriptionInfo.getDisplayName();
final int mcc = subscriptionInfo.getMcc();
final int mnc = subscriptionInfo.getMnc();
final String subscriptionInfoNumber = subscriptionInfo.getNumber();
}
对于API> = 23。要仅检查电话是否为双/三/多SIM卡:
TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
if (manager.getPhoneCount() == 2) {
// Dual sim
}
关于android - 如何在小于android.os.Build.VERSION_CODES.LOLLIPOP_MR1的sdk级别识别双SIM卡运营商名称,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/40373191/
