MediaSessionCompat:Targeting S+ (version 31 and above) 要求在创建 PendingIntent 时指定 FLAG_IMMUTABLE 或 FLAG_MUTABLE 之一 [英] MediaSessionCompat:Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent

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.

I'm trying to update my application to Android SDK 31 but I'm having an issue with MediaSessionCompat.

我有一个 MediaService，它扩展了 MediaBrowserServiceCompat() 并在该服务的 onCreate 方法中初始化了 MediaSessionCompat.

I have a MediaService that extends the MediaBrowserServiceCompat() and in method onCreate of that service I initialise the 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.

我使用的是最新版本的媒体库(androidx.media:media:1.4.0")，它能够满足 AndriodS"的这一要求.正如在 MediaSessionCompact.java 类中看到的那样.

I'm using the most recent version of media library ("androidx.media:media:1.4.0") that is able to handle the this requirement from the Andriod "S"". As it's possible to see in the MediaSessionCompact.java class.

// 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);
}

你们知道我该如何修复错误吗?

Do you guys have any idea how can I fix the error?

推荐答案

如果你没有在任何地方使用 PendingIntent.该问题可能会通过添加或更新此依赖项来解决

If you are NOT USING PendingIntent anywhere. The issue might be resolved by adding or updating this dependency

    // required to avoid crash on Android 12 API 31
    implementation 'androidx.work:work-runtime-ktx:2.7.0'

这解决了我的问题.
