react-native - 如何使用 react native 计费

Question

根据标题，一旦我使用 purchase() 方法，我的应用程序就会崩溃

在一个干净的react-native项目上进行了测试:我实际上只是发出了react-native init testProj，npm install，npm install --save react-native -billing，react-native链接react-native-billing。 然后我继续在我的 MainApplication.java

中设置 new InAppBillingBridgePackage(APP_KEY)

这是我在index.android.js中编辑的唯一代码

export default class testProj extends Component {

  componentDidMount() {
      const InAppBilling = require("react-native-billing")
      console.log(InAppBilling)

      InAppBilling.open()
          .then(() => InAppBilling.purchase('android.test.purchased'))
          .then((details) => {
              console.log("You purchased: ", details)
              return InAppBilling.close()
          })
          .catch((err) => {
              console.log(err);
          });
  }  
  render() {...}

package.json

{
  "name": "testProj",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.0.0-alpha.12",
    "react-native": "0.46.3",
    "react-native-billing": "^2.3.0"
  },
  "devDependencies": {
    "babel-jest": "20.0.3",
    "babel-preset-react-native": "2.1.0",
    "jest": "20.0.4",
    "react-test-renderer": "16.0.0-alpha.12"
  },
  "jest": {
   "preset": "react-native"
  }
}

应用到达此 componentDidMount 后，购买对话框会瞬间加载，然后在后台使我的应用和 Play 商店崩溃。在上述过程中运行 adb logcat *:E 显示:

长话短说:我错过了一些明显的东西吗？

Answer 1

使用静态响应测试应用内结算时会发生这种情况。这看起来像是新版本的 Google Play 商店的问题。我们测试了 3 个版本的 Play 商店。 7.4 可以正常工作，7.8 和 8.0 会崩溃。

目前，我们也在寻找解决方案。
