java - 广播接收器。海量数据

Question

有人知道我可以通过广播发送的最大内容大小吗？内容是否在前台传输？数据大小如何影响设备的生产力？

Answer 1

Does somebody know the max size of content which I can send via broadcast?

I would expect you to start running into problems around the 1MB mark for the entire parceled Intent, as there are limits on Binder-based IPC, which underlies the Intent system.

How the size of data affect on productivity of the device?

Since Intent objects get copied between processes as a result of broadcasts, you will consume a fair amount of RAM while the broadcast is going on, plus a fair amount of CPU time to copy the memory between processes.

I would agree with rciovati's comment: "IHMO a few kb are "huge" for passing with Intent".
