Logcat cannot detect app or package names

Same problem here with Android Studio 1.0 RC2. The Device Monitor shows the application name but in Android Studio's logcat panel, the package name is always a question mark.

I fixed the problem by Checking Tools / Android / Enable ADB Integration and then restarting adb.

A simpler way to is to Debug any app, if ADB integration is disabled, Android Studio will prompt you to enable.

You have to enable ADB integration to launch debugging. Do you want to do that?

Click Yes, of course.

Ran to the same problem on android studio.Tried connecting to the emulator(Intel emulator image with virtualization) and launched the app on the emulator and see if the application field comes back to logcat by logging with your app

Also do not forget to add - android:debuggable="true" under application in your AndroiManifest.xml

Eclipse don't see this problem because apparently Eclipse enables debugging automatically
