升级到 Android 12 (SDK 31) 后无法运行 Trusted Web Activity

Question

最近我们正在为 Android 12 做准备，我们将 compileSdkVersion 和 targetSdkVersion 更新为 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 implementation 'androidx.browser:browser:1.4.0-beta01' 后出现以下错误

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'

有没有人遇到过可以帮忙的？

Answer 1

这是一个已知问题，需要对基础 androidx.browser 库进行更改。更改在 1.4.0-rc1 中，在接下来的几周内应该会稳定下来。在android-browser-helper 中需要另一个change，一旦对androidx.browser 的更改完成，我们将发布一个更新，该更新将与targetSdk 31 配合使用。

您可以使用 android.browser 的发布候选版本并构建自己的 android-browser-helper，但我建议等待生产版本升级到目标 SDK 31。
