My logcat shows TLUI instead of app in the logcat warning messages

Question

In every app I am writing since last week, this warning with TLUI shows up in my logcat:

12-31 04:02:27.108 25942-25942/com.example.user.threads W/System:ClassLoaderreferenced unknown path: /data/app/com.example.user.threads-1/lib/arm
12-31 04:02:27.694 25942-25942/com.example.user.threads W/System:ClassLoaderreferenced unknown path: /data/app/com.example.user.threads-1/lib/arm

12-31 04:02:28.256 25942-25976/com.example.user.threads W/libEGL: [ANDROID_RECORDABLE] format: 1

(com.example.user.threads is my package name)

I don't know what TLUI means. There's nothing of that name in my PC directories. I googled and searched here also for it, but no result came up.

Also, this term always comes up with I/O errors. I reinstalled Android Studio but it's still the same. Where is the problem?

Answer 1

I see that in the logcat entries when installing my own apk as well. There is a directory /system/TLUI which, on my BLU phones, only contains a folder appicon with two png icons.

But, the libandroidfw.so on the phone looks for archives under both /data/TLUI and /system/TLUI when installing a package using adb (and also, presumably, pm). It's a harmless warning; it found and installed the package; but that's why you're seeing the message.
