【问题描述】:
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
}
...
但是我遇到了以下错误
java.lang.RuntimeException: Unable to create service com.radio.core.service.MediaService: java.lang.IllegalArgumentException: com.xxx.xxx: 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.

我正在使用最新版本的媒体库 ("androidx.media:media:1.4.0"),它能够处理来自 Andriod "S"" 的这一要求。正如在MediaSessionCompact.java 类。
// TODO(b/182513352): Use PendingIntent.FLAG_MUTABLE instead from S.
/**
* @hide
*/
@RestrictTo(LIBRARY)
public static final int PENDING_INTENT_FLAG_MUTABLE =
Build.VERSION.CODENAME.equals("S") ? 0x02000000 : 0;
...
if (mbrComponent != null && mbrIntent == null) {
// construct a PendingIntent for the media button
Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
// the associated intent will be handled by the component being registered
mediaButtonIntent.setComponent(mbrComponent);
mbrIntent = PendingIntent.getBroadcast(context,
0/* requestCode, ignored */, mediaButtonIntent,
PENDING_INTENT_FLAG_MUTABLE);
}

你们知道我该如何解决这个错误吗?

根据
TODO的评论,看来这个库需要更新。尽管182513352可能是私人问题,但我认为这不是公开问题。请注意,在您绝对需要targetSdkVersion 31之前,您有一年的时间和变化,因此您可能希望回落到 30,直到此库得到更新。 -
错误 182513352 已在此提交 android.googlesource.com/platform/frameworks/support/+/… 上得到修复,并基于来自 androidx.media:media 的版本 1.3.0-rc02 (developer.android.com/jetpack/androidx/releases/media) 的发布说明,它已经发布
-
androidx.media:media: 的最新版本是 1.4.0。链接:developer.android.com/jetpack/androidx/releases/media你用过这个版本吗?
-
@HarisDautović 是的,我试过那个。我会用那个版本更新我的问题
