android 获取iccid imsi

网上关于这些挺多的，不过没找到关于双卡的以及未插卡的异常处理，我的需求是在settings里面添加菜单显示iccid imsi，记录一下

(一)在设置-关于手机显示iccid imsi

1.在packages/apps/Settings / res/xml/my_device_info.xml添加菜单

    <!-- Device imsi display -->
    <Preference
        android:key="imsi"
        android:order="34"
        android:title="@string/imsi"
        settings:controller="com.android.settings.deviceinfo.imsi.ImsiInfoPreferenceController"/>

    <!-- Device imsi display -->
    <Preference
        android:key="iccid"
        android:order="36"
        android:title="@string/iccid"
      settings:controller="com.android.settings.deviceinfo.iccid.IccidInfoPreferenceController"/>

2.在packages/apps/Settings / src/com/android/settings/deviceinfo/aboutphone/MyDeviceInfoFragment.java添加ImsiInfoPreferenceController，IccidInfoPreferenceController

//wangdonghai add begin
import com.android.settings.deviceinfo.imsi.ImsiInfoPreferenceController;
import com.android.settings.deviceinfo.iccid.IccidInfoPreferenceController;
//wangdonghai add end
import java.util.ArrayList;
import java.util.List;
import android.util.Log;

@SearchIndexable
public class MyDeviceInfoFragment extends DashboardFragment
        implements DeviceNamePreferenceController.DeviceNamePreferenceHost {

    private static final String LOG_TAG = "MyDeviceInfoFragment";
    private static final String KEY_MY_DEVICE_INFO_HEADER = "my_device_info_header";
    // Add for Local system update
    private static String KEY_RECOVERY_SYSTEM_UPDATE = "RecoverySystemUpdate";

    private BuildNumberPreferenceController mBuildNumberPreferenceController;

    @Override
    public int getMetricsCategory() {
        return SettingsEnums.DEVICEINFO;
    }

    @Override
    public int getHelpResource() {
        return R.string.help_uri_about;
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        use(ImeiInfoPreferenceController.class).setHost(this /* parent */);
        use(DeviceNamePreferenceController.class).setHost(this /* parent */);
        //wangdonghai add begin 
        use(ImsiInfoPreferenceController.class).setHost(this /* parent */);
        use(IccidInfoPreferenceController.class).setHost(this /* parent */);
        //wangdonghai add  end 
        mBuildNumberPreferenceController = use(BuildNumberPreferenceController.class);
        mBuildNumberPreferenceController.setHost(this /* parent */);
    }

3，新建IccidInfoPreferenceController.java
