定位到 Android 12 时，应用因 pendingIntent 而崩溃

Question

当定位到 android 12 时，由于 Nearby message API，应用程序崩溃了。这是崩溃日志

2021-10-07 18:59:44.916 10343-10384/com.example.nearbymessagescanner E/AndroidRuntime: FATAL EXCEPTION: GoogleApiHandler
Process: com.example.nearbymessagescanner, PID: 10343
java.lang.IllegalArgumentException: com.example.nearbymessagescanner: 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.

即使我为 pendingIntent

添加了标志 PendingIntent.FLAG_MUTABLE 或 PendingIntent.FLAG_IMMUTABLE，也会发生此异常

    private fun backgroundSubscribe() {
    Log.d(TAG, "Subscribing for background updates.")
    val options = SubscribeOptions.Builder().setStrategy(Strategy.BLE_ONLY).build()
    messagesClient.subscribe(pendingIntent, options)
}

    private val pendingIntent: PendingIntent
    get() = PendingIntent.getBroadcast(
        this,
        0,
        Intent(this, BeaconMessageReceiver::class.java),
        PendingIntent.FLAG_MUTABLE
    )

这是一个 sample app，可以通过单击应用程序中的订阅按钮来重现此问题。我使用的是18.0.0版本的play-services-nearby

implementation 'com.google.android.gms:play-services-nearby:18.0.0'

Answer 1

听起来很奇怪，但修复是添加工作管理器依赖项 2.7.0+：implementation "androidx.work:work-runtime:2.7.0"
您必须更新应该支持 Android 12 制动更改的依赖项（我必须更新一些第三方）。在 github 和文档页面
上检查
此外，一些图书馆正在使用 Android 12 所需的权限 <uses-permission android:name="com.google.android.gms.permission.AD_ID"/>。请查看此权限的文档
此外，检查 google's issue tracker 是否存在与 Android 12
有关的 google 库特定问题

也许我错过了什么，但所有这些都帮助我迁移了。祝你好运:)

我能够通过添加 Xamarin.AndroidX.work.runtime NuGet 包解决 Xamarin 项目的这个问题。
