我正在尝试将我的应用程序升级到 Android SDK 31,但是我在 MediaSessionCompat 上遇到了一个问题。
我有一个 MediaService,它扩展了 MediaBrowserServiceCompat () ,在该服务的方法 onCreate 中,我初始化了 MediaSessionCompat。
override fun onCreate() {
super.onCreate()
mediaSession = MediaSessionCompat(this, TAG).apply {
setCallback(mediaSessionCallback)
isActive = true
}
...
但我有以下错误
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.

我正在使用媒体库的最新版本(“ androidx.media: media: 1.4.0”) ,它能够处理来自 Andriod“ S”的这个需求。可以在 MediaSessionCompact.java 类中看到。
// 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);
}
