我正在尝试将我的应用程序更新到 Android SDK 31,但我遇到了 MediaSessionCompat 问题。
我有一个扩展 MediaBrowserServiceCompat() 的 MediaService,并在该服务的 onCreate 方法中初始化 MediaSessionCompat。
override fun onCreate() {
super.onCreate()
mediaSession = MediaSessionCompat(this, TAG).apply {
setCallback(mediaSessionCallback)
isActive = true
}
...

如果您不在PendingIntent任何地方使用。通过添加或更新此依赖项可以解决该问题
// required to avoid crash on Android 12 API 31
implementation 'androidx.work:work-runtime-ktx:2.7.1'

这解决了我的问题。
您可以./gradlew app:dependencies在项目的终端中执行,并发现哪些依赖项包括旧版本的工作运行时。然后您可以尝试升级该依赖项以努力做正确的事情

解决了仅适用 PendingIntent.FLAG_MUTABLE于 Android 版本 12 或更高版本的此错误
PendingIntent pendingIntent = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) {
pendingIntent = PendingIntent.getActivity
(this, 0, notificationIntent, PendingIntent.FLAG_MUTABLE);
}
else
{
pendingIntent = PendingIntent.getActivity
(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
}

PendingIntent如果您的应用面向 Android 12,则必须指定应用创建的每个对象的可变性。
在您的情况下,android.support.v4.media.session.MediaSessionCompat负责PendingItent在初始化期间创建MediaSessionCompat。
解决方案:@constructor幸运的是,该类
有一个附加的MediaSessionCompat,因此我们可以pendingItent作为参数传递。如果我们为component参数传递 null,它将在库中初始化。
override fun onCreate() {
super.onCreate()
val mediaButtonIntent = Intent(Intent.ACTION_MEDIA_BUTTON)
val pendingItent = PendingIntent.getBroadcast(
baseContext,
0, mediaButtonIntent,
PendingIntent.FLAG_IMMUTABLE
)
mediaSession = MediaSessionCompat(baseContext, TAG, null, pendingItent).also {
it.isActive = true
}
sessionToken = mediaSession.sessionToken
packageValidator = PackageValidator(this@MediaService, R.xml.allowed_media_browser_callers)
}

源代码: https: //github.com/dautovicharis/issue-media-session-compat
更新:感谢转到:
在1.3.0版本中,MediaSessionCompat发生了新的变化,根据 TODO(b/182513352) 注释,我们可以清楚地看到缺少与 Android 12 相关的内容。
在新androidx.media:media:版本发布之前,使用我提供的解决方法应该可以正常工作。
更新:我们希望TODO(b/182513352)将在即将发布的版本中得到修复。在那之前,我们可以在支持的implementation "androidx.media:media:1.3.0-rc02地方使用“ FLAG_IMMUTABLE。

如果您没有在应用程序中使用挂起的意图,请尝试这个。实现 'androidx.work:work-runtime-ktx:2.7.0'
否则如果您正在使用挂起的意图,则更改此
pendingIntent = PendingIntent.getActivity(
this,
0, intentToLaunchThisActivityFromNotification,
PendingIntent.FLAG_UPDATE_CURRENT);

如果有人仍然面临 Android 12 的崩溃问题,请确保在 AndroidMenifest.xml 中添加以下内容
<activity
...
android:exported="true" // in most cases it is true but based on requirements it can be false also
>
// If using react-native push notifications then make sure to add into it also
<receiver
android:name="com.dieam.reactnativepushnotification.modules.RNPushNotificationBootEventReceiver" android:exported="true">

显然 play-services-ads:20.4.0 依赖于不支持 sdk 31 的工作运行时版本。
这对我有用 ->

notification.java 中的更改
PendingIntent.FLAG_IMMUTABLE
100% 工作
使用 Android 版本 12 或 S 升级应用程序目标,仅使用 PendingIntent.FLAG_MUTABLE 和 PendingIntent.FLAG_IMMUTABLE
int intentFlagType = PendingIntent.FLAG_ONE_SHOT;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) {
intentFlagType = PendingIntent.FLAG_IMMUTABLE; // or only use FLAG_MUTABLE >> if it needs to be used with inline replies or bubbles.
}
PendingIntent pendingIntent = PendingIntent.getActivity(context, notificationID, intent, intentFlagType);

就我而言,原因是旧版本的 Chuck 库。
我已经把它从
implementation 'com.readystatesoftware.chuck:library:1.1.0'

到新的实施,例如

}
val client = OkHttpClient.Builder()
.addInterceptor(ChuckerInterceptor(context))
.build()
android {
compileOptions {

targetCompatibility JavaVersion.VERSION_1_8

// For Kotlin projects add also this line
