最近我们正在为Android 12做准备，我们将compileSdkVersion和targetSdkVersion更新到31更新到31后，TWA无法启动。给出的错误是

    java.lang.IllegalArgumentException: xxx.twa: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

更新 androidx.browser:browser 后implementation 'androidx.browser:browser:1.4.0-beta01'出现以下错误

我试图找到 com.google.androidbrowserhelper 的更新版本，但找不到任何内容。我目前正在使用implementation 'com.google.androidbrowserhelper:androidbrowserhelper:2.2.2'

有没有人遇到这种情况并能够提供帮助？

这是一个已知问题，需要对底层androidx.browser库进行更改。更改在 中1.4.0-rc1，在接下来的几周内应该会保持稳定。需要进行另一项更改android-browser-helper，一旦更改androidx.browser完成，我们将发布一个可与 targetSdk 31 良好配合的更新。

您可以使用 android.browser 的 release-candidate 版本并构建您自己的 android-browser-helper，但我建议等待生产版本升级到目标 SDK 31。
