实现androidx.work:work-runtime:2.7.1

来自:

https://developer.android.com/reference/android/app/PendingIntent#FLAG_MUTABLE

"Up until Build.VERSION_CODES.R, PendingIntents are assumed to be mutable by default, unless FLAG_IMMUTABLE is set. Starting with Build.VERSION_CODES.S, it will be required to explicitly specify the mutability of PendingIntents on creation with either (@link #FLAG_IMMUTABLE} or FLAG_MUTABLE. It is strongly recommended to use FLAG_IMMUTABLE when creating a PendingIntent. FLAG_MUTABLE should only be used when some functionality relies on modifying the underlying intent, e.g. any PendingIntent that needs to be used with inline reply or bubbles."

为了保持相同的行为，像每天改变任何“PendingIntent。FLAG_MUTABLE |任何东西"

当创建/检索一个挂起的意图/活动，服务，提供者，接收者

值得寻找的地方:

PendingIntent.getBroadcast(...

.getPendingIntent(...

PendingIntent.getService

PendingIntent.getActivity

如果你的应用程序使用androidx。工作确保至少升级到:

implementation 'androidx.work:work-runtime-ktx:2.7.0-alpha05'

他们在alpha02中修复了一个与SDK 12中所有这些更改相关的错误。

我遇到过致命异常:java.lang.IllegalArgumentException这样的崩溃。不发布。附加到带有远程输入的操作的PendingIntents必须是可变的。

我写了这个util方法，它允许将可变性作为参数发送。有时需要获取可变标志，例如通知中的回复操作。

private fun getPendingIntentFlags(isMutable: Boolean = false) =
    when {
        isMutable && Build.VERSION.SDK_INT >= Build.VERSION_CODES.S ->
            PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_MUTABLE

        !isMutable && Build.VERSION.SDK_INT >= Build.VERSION_CODES.M ->
            PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE

        else -> PendingIntent.FLAG_UPDATE_CURRENT
    }

使用的例子:

val quickReplyPendingIntent = PendingIntent.getBroadcast(
                context, notificationId, replyIntent,
                getPendingIntentFlags(true)
            )

如果您没有使用最新版本的WorkManager，就会看到这个问题。在2.7.0-alpha02版本中已修复:

使PendingIntent可变显式，以修复针对Android 12时的崩溃

请记住，2.7.0-alpha02只与Android 12开发者预览1 SDK兼容。所以你可能想要等到它进入beta版或RC版。

2021年4月21日更新-为任何谷歌搜索该问题的人添加这个答案，您可能遇到的错误可能是这样的:

java.lang.IllegalArgumentException: com.myapp.myapp: Targeting S+ (version 10000 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.

你不需要在你的应用中直接使用WorkManager来查看这个崩溃。

如本文所述，解决方案是向构建中添加依赖项。Android 12版本的gradle文件:

 implementation 'androidx.work:work-runtime-ktx:2.7.0-alpha05'

注意，无论你使用的是Java、Kotlin +协程、RxJava2、GCMNetworkManager等等，这种依赖关系都是不同的。所以一定要检查上面的还原。

显然，用最新的版本号替换上面的版本号。如前所述，它不兼容android-13之前的版本。

我创建了PendingIntentCompat。将PendingIntent逻辑抽象到一个单独的类中。

object PendingIntentCompat {

    @JvmStatic
    @JvmOverloads
    fun getActivity(
        context: Context,
        requestCode: Int,
        intent: Intent,
        flags: Int,
        isMutable: Boolean = false
    ): PendingIntent {
        return PendingIntent.getActivity(
            context,
            requestCode,
            intent,
            addMutabilityFlags(isMutable, flags)
        )
    }

    @JvmStatic
    @JvmOverloads
    fun getService(
        context: Context,
        requestCode: Int,
        intent: Intent,
        flags: Int,
        isMutable: Boolean = false
    ): PendingIntent {
        return PendingIntent.getService(
            context,
            requestCode,
            intent,
            addMutabilityFlags(isMutable, flags)
        )
    }

    @JvmStatic
    @JvmOverloads
    @RequiresApi(Build.VERSION_CODES.O)
    fun getForegroundService(
        context: Context,
        requestCode: Int,
        intent: Intent,
        flags: Int,
        isMutable: Boolean = false
    ): PendingIntent {
        return PendingIntent.getForegroundService(
            context,
            requestCode,
            intent,
            addMutabilityFlags(isMutable, flags)
        )
    }

    /**
     * https://developer.android.com/about/versions/12/behavior-changes-12#pending-intent-mutability
     */
    private fun addMutabilityFlags(isMutable: Boolean, flags: Int): Int {
        var updatedFlags = flags

        if (isMutable) {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
                updatedFlags = flags or PendingIntent.FLAG_MUTABLE
            }
        } else {
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                updatedFlags = flags or PendingIntent.FLAG_IMMUTABLE
            }
        }
        return updatedFlags
    }
}

下面是我在KOTLIN中从30移动到33的用例。

1. 添加媒体依赖

implementation "androidx.media:media:1.4.1"

2. 更新工作管理器

 implementation "androidx.work:work-runtime-ktx:2.7.0"

3.更新不变的

fun getImmutableFlag() = if(isAndroidAPI31())  PendingIntent.FLAG_IMMUTABLE or PendingIntent.FLAG_UPDATE_CURRENT else 0

fun isAndroidAPI31() = android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S

private fun createOpenAppIntent(context: Context): PendingIntent {
        val intent = Intent(context, MainActivity::class.java).apply {
            flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP
        }
        return PendingIntent.getActivity(context, 0, intent, getImmutableFlag())
    }

4. 如果在所有活动、服务、提供者、接收者中未添加，则在清单中添加导出标签

android:exported="true"

希望这能起作用，祝你愉快。
