Whats is taco memory and why am I low on it?

04-23 23:06:09.458: ERROR/taco(1350): LowMemory.

I const开发者_开发百科antly see this in logcat, but what does it mean?

This is what the log line you posted means:

• The 04-23 23:06:09.458 is a timestamp for April 23rd, 11:06 PM.
• The log statement is of Log level ERROR.
• taco is an application-specific tag that is being passed into the Logger.
• The (1350) is the originating process Id.
• LowMemory is the message the application (the afformentioned taco) has requested be logged.

There's more information about what's contained in Logcat messages (and how to filter them) on the the Android Developer Site about ADB.

If you're curious about that specific log statement, the first step is figuring out what application is logging using the taco log tag and why (or at least when) it's logging this message.
