如何解决android studio项目中的信号实现问题
我遇到了类似的问题,错误是:
MainApplication.java:91: error: cannot find symbol
OneSignal.getNotifications().requestPermission(Continue.with(r -> {
^
symbol: variable Continue
location: class MainApplication
修复方法是将这段代码完全注释掉,如代码上方的注释所示:
// requestPermission will show the native iOS notification permission prompt.
// We recommend removing the following code and instead using an In-App Message to prompt for notification permission
不幸的是,文档已过时,此评论不正确,因为它提到了“本机 iOS 通知权限提示”。
考虑到这是 Android,这很可能是“复制粘贴”,他们只是复制并粘贴了大部分代码和文档,并且没有非常仔细地校对。
无论如何,注释掉此部分允许构建 android 版本。 (我正在使用 React Native)。
或者更好的是,您甚至可以删除代码,尽管您需要找出提示用户通知权限的正确方法。
这是我注释掉的原始代码:
// OneSignal.getNotifications().requestPermission(Continue.with(r -> {
// if (r.isSuccess()) {
// if (r.getData()) {
// // `requestPermission` completed successfully and the user has accepted permission
// }
// else {
// // `requestPermission` completed successfully but the user has rejected permission
// }
// }
// else {
// // `requestPermission` completed unsuccessfully, check `r.getThrowable()` for more info on the failure reason
// }
// }));
