Question

我在Genymotion Android模拟器和我的Huawei Nexus 6P上都发生了一次奇怪的崩溃。我有一个截图，我正在成功发送给另一个Anko Component - 显然它是Parcelable：

@Parcelize
data class ColourBoardScreenShot(var screenshot: @RawValue BitmapDrawable) : Parcelable

但是，如果我拍摄截图并且随后通过按屏幕底部的圆形按钮退出应用程序，应用程序将崩溃并显示以下堆栈跟踪：

谁能告诉我哪里出错？

修改：

如果我尝试使用插件替换ColourBoardScreenShot来生成Parcelize代码，我会在Unresolved reference和read上获得write：

data class ColourBoardScreenShot(var screenshot: @RawValue BitmapDrawable) : Parcelable {
constructor(source: Parcel) : this(
        source.read[@kotlinx.android.parcel.RawValue] BitmapDrawable ()
)

override fun describeContents() = 0

override fun writeToParcel(dest: Parcel, flags: Int) = with(dest) {
    write[@kotlinx.android.parcel.RawValue] BitmapDrawable (screenshot)
}

companion object {
    @JvmField
    val CREATOR: Parcelable.Creator<ColourBoardScreenShot> = object : Parcelable.Creator<ColourBoardScreenShot> {
        override fun createFromParcel(source: Parcel): ColourBoardScreenShot = ColourBoardScreenShot(source)
        override fun newArray(size: Int): Array<ColourBoardScreenShot?> = arrayOfNulls(size)
    }
}
}

Answer 1

我将ColourBoardScreenShot更改为以下内容：

@Parcelize
data class ColourBoardScreenShot(var screenshot: ByteArray) : Parcelable

因此我使用@RawValue BitmapDrawable代替ByteArray而停止了崩溃。

如果在某些时候使用了Parcelised数据，我退出应用程序时Android应用程序崩溃，即使该数据已成功分区
