我遇到onServiceDisconnected (crash or killed by oom)错误。该错误是随机发生的。我正在做的就是使用相机api2捕获图像并创建base64并使用glide加载它。图像数量没有限制，因此，如果用户单击约30张图像并使用glide加载图像，那么一段时间后，我会收到onServiceDisconnected (crash or killed by oom)错误。不知道错误在哪里发生。单击图片时，我还将image bytes放入字节数组。此字节数组稍后用于创建实际图像并将其保存在本地。
所以我不确定在哪里可能出现此错误。任何帮助将不胜感激。

单击图像时，我将图像的base64以及字节保存在数组中。该图像尚未保存到移动存储中。允许用户查看单击的图像列表，并删除列表或向列表中添加更多图像（此列表是从base64数组加载的）。用户可以保存图像，这时，实际图像将在移动存储中创建并上传到服务器。将其同步到服务器后，用户可以返回并进行编辑。删除任何图像或添加更多图像。在这里，加载图像时它将来自服务器，即通过URL。新添加的图像将位于base64中。
不确定在哪里发生内存不足错误。
