Unexpected value from nativeGetEnabledTags: 0

I installed the latest version of the SDK (r21) and ADT 21.0.0. I tried simple code, and it works well, but now I get a warning in LogCat that did not appear in the previous versions:

Unexpected value from nativeGetEnabledTags: 0

I googled it, and I found Issue 39723: Emulator spams LogCat with "Unexpected value from nativeGetEnabledTags: 0" message.

What does it mean?

Solution 1:

I just ran into this problem, too. As a workaround I'm filtering the LogCat output with the following expression on the by Log Message field of the filter:

^(?!.*(nativeGetEnabledTags)).*$ 

Otherwise it is so spammed it's almost useless.

Following Laksh suggestion, if you want to filter this always without having to always write it on the Search for messages field:

1. Goto your Logcat
2. In the Saved Filters part on the left, click on the Edit selected logcat filter (If Saved Filters is not visible then click on Display Saved Filters View in the Logcat)
3. There, in the by Log Message field, enter ^(?!.*(nativeGetEnabledTags)).*$.

Solution 2:

It's a bug in the emulator System Image for API 17.

At the moment, your workarounds are the following:

If you DON'T need API level 17

• Use an emulator with API 16 (or lower)...
• ...or higher (API 19 for instance, tested to solve the problem too).

If you DO need API level 17

• Use a real device: Nexus 4, Nexus 7, Nexus 10.
• Use the LogCat filter suggested by Hendrik. You'll have to edit every single filter you have, though (If you want to fix them all).

Solution 3:

The link which you referred to has the answer. It is a bug introduced in the latest revision of the tools. In the followup comments you can read that a google representative says a fix is on the way.
