Question

目前我正在制作一个音乐播放器应用，我在其中为控制播放器创建自定义通知，并在锁定屏幕上使用remotecontrolclient作为背景图片，在轨道更改时更新通知和艺术作品。但在改变时我得到了这个错误：

我的setupMediaplayer代码在这里：

mNotification.bigContentView.setImageViewResource(R.id.playpause, R.drawable.ic_pause_circle_outline_white_48dp)
    mNotification.contentView.setImageViewResource(R.id.playpause, R.drawable.ic_pause_circle_outline_white_48dp)
    mNotification.bigContentView.setTextViewText(R.id.track_title, mTrackItems.get(mCurrentposition).mTitle)
    mNotification.contentView.setTextViewText(R.id.track_title, mTrackItems.get(mCurrentposition).mTitle)
    mNotification.bigContentView.setTextViewText(R.id.track_label, mTrackItems.get(mCurrentposition).mLabel)
    mNotification.contentView.setTextViewText(R.id.track_label, mTrackItems.get(mCurrentposition).mLabel)
    Picasso.with(this).load(mTrackItems.get(mCurrentposition).mArtwork).into(object : Target{
        override fun onBitmapLoaded(notibitmap: Bitmap?, from: Picasso.LoadedFrom?) {
            if (!notibitmap!!.isRecycled){
                mBitmapImage = Bitmap.createBitmap(notibitmap)
                try {
                    mNotification.bigContentView.setImageViewBitmap(R.id.art_work,notibitmap)
                    mNotification.contentView.setImageViewBitmap(R.id.art_work,notibitmap)
                    mNotificationManager.notify(SharedPref.FOREGROUNDNOTICE_ID,mNotification)
                    if (UtilsFunctions.currentVersionSupportLockScreenControls()){
                        updateRemoteControlClientMetadata(mBitmapImage!!)
                    }
                } catch (el : IllegalStateException){                
                    Log.d(TAG,el.toString())
                    if (UtilsFunctions.currentVersionSupportLockScreenControls()){
                        updateRemoteControlClientMetadata(mBitmapImage!!)
                    }
                }
            }
            Log.d(TAG,"setup media player bitmap.isRecycled(): "+notibitmap.isRecycled)
        }
        override fun onBitmapFailed(errorDrawable: Drawable?) {
        }
        override fun onPrepareLoad(placeHolderDrawable: Drawable?) {
        }
    })
    isstart = false
    val mUrl : String = mTrackItems.get(mCurrentposition).mStreamUrl+soundcloud_clientid
    Log.d(TAG,"On Media player Setmediaplayer with stream "+mUrl)
    mMedaiPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC)
    try {
        mMedaiPlayer.setDataSource(mUrl)
        mMedaiPlayer.prepareAsync()
        mMedaiPlayer.setOnPreparedListener(this)
        mMedaiPlayer.setOnCompletionListener(this)
    } catch (el : IllegalStateException){
        Log.d(TAG,"Illegalstate Exception"+el.toString())
        mMedaiPlayer.reset()
    } catch (ei : IOException){
        Log.d(TAG,"IO Exception"+ei.toString())
        mMedaiPlayer.reset()
    } catch (e : Exception){
        Log.d(TAG,"Exception"+e.toString())
        mMedaiPlayer.reset()
    }

更新remotecontrolclient的代码在这里：

if (myRemoteControlClient != null) {
        val editor = myRemoteControlClient!!.editMetadata(true)
        editor.putBitmap(RemoteControlClient.MetadataEditor.BITMAP_KEY_ARTWORK,mBitmapImage)
        editor.apply()
        Log.d(TAG,"after update remote bitmap.isRecycled(): "+editor.getBitmap(RemoteControlClient.MetadataEditor.BITMAP_KEY_ARTWORK,mBitmapImage).isRecycled)
    }

我在stackoverflow上读了一些帖子，这说明我的位图是由remotecontrolclient回收的，但是我保持位图的轨迹是否被回收，所有日志显示为false意味着我的位图不被回收。我在哪里做错了以及如何解决这个问题

Answer 1

在我的项目中，我遇到了与这些日志相同的异常。我的代码不同，但错误就行了

bitmap.recycle();

在使用位图进行一些大小修改的一些操作之后。我刚删除了这一行，现在一切都很好。没有必要（回收）

无法包含回收的位图
