Answer 1

如果您使用 react-native>=60.0，则无需使用react-native link react-native-imei。它将自动链接。

由于此包读取手机的状态，因此您必须将 <uses-permission android:name="android.permission.READ_PHONE_STATE" /> 添加到 android/app/src/main/AndroidManifest.xml 此文件中。

在 SDK 版本 23 之前的设备上，如果权限出现在清单中，则会自动授予权限。否则，您必须遵循此程序。

import { PermissionsAndroid } from 'react-native';

try {
  const granted = await PermissionsAndroid.request(
    PermissionsAndroid.PERMISSIONS.READ_PHONE_STATE,
    {
      title: "Phone State's Permission",
      message: "This app needs access to your phone's state",
      buttonNeutral: "Ask Me Later",
      buttonNegative: "Cancel",
      buttonPositive: "OK"
    }
  );
  if (granted === PermissionsAndroid.RESULTS.GRANTED) {
    console.log("You can read phone's state");

    IMEI.getImei().then(imeiList => {
      console.log("imeiList"); // prints ["AABBBBBBCCCCCCD"]
      console.log(imeiList); // prints ["AABBBBBBCCCCCCD"]
    });
  } else {
    console.log("Permission denied");
  }
} catch (err) {
  console.warn(err);
}

希望对你有帮助。

/home/zain/Desktop/Kolachi/demo/pos-proto/android/app/src/main/java/com/resturantapp/MainApplication.java:82： 错误：不兼容的类型：MainReactPackage 无法转换为 int packages.add(new MainReactPackage(),

这是错误，你能检查一下为什么在你的 android src/main.java/com/restaurantapp 文件夹中的 MainApplication.java 中添加了 MainReactPackage。实际上删除或注释掉下面的行并再次运行该项目。

packages.add(new MainReactPackage(),

您不再需要添加软件包。 RN0.60及以上支持自动链接。我注释掉了我的包，因为它们不再需要了。
