Android Studio 3.1 Logcat prefix not always showing and breaking pretty logger

Question

Since the new version of Android Studio (3.1) the Logcat window doesn't always show the prefix (03-28 12:43:01.091 nl.test.app D/log). I made my own logger, which prints in a pretty way, but this gets broken since some lines are no longer with the same indentation. I'll show an example below.

03-28 12:43:01.091 nl.test.app D/log: ╔═══════════════════════════════════════════════════════════════════════════════════════
    ║ [ (TestActivity.kt:33)#OnCreate ] 
    ║ This is my test log
03-28 12:43:01.092 nl.test.app D/log: ║ This is my second test log
    ╚═══════════════════════════════════════════════════════════════════════════════════════

This is how it used to be:

03-28 12:43:01.091 nl.test.app D/log: ╔═══════════════════════════════════════════════════════════════════════════════════════
03-28 12:43:01.091 nl.test.app D/log: ║ [ (TestActivity.kt:33)#OnCreate ] 
03-28 12:43:01.091 nl.test.app D/log: ║ This is my test log
03-28 12:43:01.092 nl.test.app D/log: ║ This is my second test log
03-28 12:43:01.092 nl.test.app D/log: ╚═══════════════════════════════════════════════════════════════════════════════════════

Is there a way I can fix this?

Answer 1

According to the issue tracker (https://issuetracker.google.com/issues/77305804) it is fixed and is planned for Android Studio 3.2. To quote from the issue tracker:

This change in behavior was inadvertent and I reverted it. The fix will go out in 3.2.

It does not say when this version will be released. But I'll update my answer as soon as I know.

Edit

Android Studio 3.2 is released and my pretty logger is working again!

Answer 2

The observation is correct. In Android Studio 3.1.4 it is also broken. Not only the prefix is not printed always, also complete lines dissappear.

But there is a small workaround:

1. open the Terminal Window in Android Studio

2. start a shell in your target:

   C:\directory> adb shell

3. in that shell start logcat with grep as filter:

   device:/ $ logcat | grep

4. than you see all filtered entries with all contents
