Android log system
Android log system<div class="postText"><div id="cnblogs_post_body">There are basically three logs on the system:
Log:
[*]for short, textual data
[*]in-memory ringbuffer, fast
[*]ephemeral (you'll lose it on a crash, or the ringbuffer scrolls)
[*]intended for app developers
EventLog is:
[*]for short, binary data
[*]in-memory ringbuffer, fast
[*]ephemeral (you'll lose it on a crash, or the ringbuffer scrolls)
[*]intended for platform developers to collect statistics
DropBox:
[*]for long text or binary data
[*]persistent, written to disk
[*]kinda slow (disk)
[*]meant for platform developers too, mostly to collect crashes & large statistics
[*]subject to limits, deleted by tag if a tag's count and/or size get too large
DropBox is what we used during development to capture all the StrictMode violations in Gingerbread.
You can use DropBox for one-off debugging, but it's not really recommended. It's definitely not recommended as a way to share data between apps. It's not reliable enough, and you can't put permissions on the data. You should just use a shared userid and use the normal filesystem with appropriate permissions.
