通过查看，我可以说问题出在RoomVideoConverter.fromBitmapToBase
这是RoomVideoConverter
class RoomVideoConverter {
@TypeConverter
fun fromBase64ToBitmap(base64Value: String): Bitmap? {
val decodedBytes: ByteArray = Base64.decode(base64Value,0)
return BitmapFactory.decodeByteArray(decodedBytes,decodedBytes.size)
}
@TypeConverter
fun fromBitmapToBase64(bitmap: Bitmap?): String {
val byteArrayOS = ByteArrayOutputStream()
bitmap?.compress(Bitmap.CompressFormat.PNG,25,byteArrayOS)
return Base64.encodetoString(byteArrayOS.toByteArray(),Base64.DEFAULT)
}
}
RoomDatabase在这里，
@Database(entities = [VideoInfo::class,Link::class],version = 1,exportSchema = false)
@TypeConverters(RoomVideoConverter::class)
abstract class AppDatabase : RoomDatabase() {
abstract fun videoProgressDao() : VideoProgressDao
}
我正在使用TypeConverter将位图转换为Base64字符串以将其存储到数据库表中。
注意：：我正在使用WorkManager从网络下载视频，并且数据库交易发生在doWork()的{{1}}中。现在，当我下载1个视频时，不会崩溃，而同时下载多个视频时，只会崩溃。这可能是CoroutineWorker的问题吗？如果是这样，如何使TypeConverter线程安全以避免崩溃？
有人可以帮我吗？
谢谢。
