推荐答案
您可以使用 React Native 应用程序上下文并从那里获取包管理器.
You can use the react native application context and get the package manager from there.
PackageManager manager = reactContext.getPackageManager();
或者只是从当前活动中获取
or just get it from the current activity
Activity currentActivity = getCurrentActivity();
PackageManager manager = currentActivity.getPackageManager();
