How to listen in Android when the browser or some app started downloading a files?

Question

I need an application which will listen when some application starts downloading files (it will be evaluated like malicious behavior).

I was trying to do this with BroadcastReceiver and Intents, when I was filtering the " android.intent.action.DOWNLOAD_COMPLETE " (in xml) and show it into Toast , when some item was downloaded to the device, but it was not working for me.

I found now that there is exist a DownloadListener , which contains a onDownloadStart(..) method.

Do you think, that this can solve my problem?

Short of a custom version of the OS, you can't. At best, you could get a subset of requests that use DownloadManager. But most downloads don't use that- they just make direct HTTP requests. There's no way to track those from another application. If you were to use a custom version of the OS you could, but to get everything you'd pretty much need to be built into the Linux networking subsystem.
