Android Studio No LogCat

Question

Android Studio is just killing me. I'm migrating over from Eclipse and am unable to produce LogCat output. I just created a simple hello world app complete with a single line of System.out.println("hello world"); Regardless of whether I run this on an emulator or on a USB device, I get no LogCat output.

I reinstalled Android Studio, and then I got the correct output for a few executions. Now I'm back to no output. I tried restarting the computer, but this didn't correct anything.

Obviously, I can't reinstall the program every time LogCat output stops being produced, and I can't program without the ability to see console output. I'm beyond frustrated.

Here are a couple of clues:

1. Occasionally, I will get this error:
2. I am unable to run adb from the command line. Since I installed my SDK along with Android Studio, I have no idea where the adb application exists, so I don't know how to add it to my PATH variable. Even so, I don't think that this has anything to do with why LogCat output isn't produced by Android Studio.

I have tried restarting the LogCat by clicking on the icon, but this does nothing.

I realize that there are many other posts on this same type of issue, but the solutions suggested there are not resolving my issue. I am grateful for any help.

Answer 1

1) Don't use System.out.println. Import android.util.Log and then use

Log.e("Randall", "Hello World");

Additionally, adb should be found in your

sdk/platform-tools/adb

folder

Answer 2

我以前没有用过android studio，我是蚀家伙，但是也许您应该尝试Log.d（）...
