Hello,

First, a few sanity checks to start debugging this. Is ADB integration enabled in Android Studio? Its located in Tools, Android, Enable ADB Integration. Second, do you see any output when you run the command "adb logcat" from a terminal?

Sometimes Android Studio likes to stop gathering logcat data so before you begin your test, you should clear Android Studio's logcat info and then click the resume gathering logcat button.

Hello,

The other thing that I can think of off the top of my head is to make sure USB debugging is enabled on your phone. You will need to enable Developer options by going to Settings, About Phone, and tap the Android version 7 times. After this, go to Settings, Developer Options, and enable USB debugging. You will hopefully have a dialog open up when you connect it to your computer asking if you want to allow your computer access, accept it.

I want to make sure the basics are all right. Do you get any output from the command "adb devices"? If so, does it say device at the end of the line with the serial number of your phone? Or something like offline, no permission. Also, let me know if it says ?????????? instead of your DSN.

Mine got fixed with a clean and rebuild of the project. Also see if you are declaring the LOG variable in the MainActivity class and not in it's member functions like onCreate.

Hello,

What OS are you running? When you type in "adb devices" into a terminal window while the phone is connected what is the output?

OS X 10.10.3, Android Studio 2. adb is enabled but when i run adb logcat, no output. i ran ./adb --help, bash: adb: command not found. i thought maybe this is because my adb is not setup i tried some help from stackoverflow(http://stackoverflow.com/questions/17901692/set-up-adb-on-mac-os-x), tried this command in terminal in android studio(echo 'export PATH=$PATH:/Users/akashdeepsingh/android-sdks/platform-tools/' >> ~/.bash_profile). and still no log and cant even run the app in debugger mode. this is driving me crazy. P.S. All Update done, if their is some special update that i should crosscheck. help

I think I've found a fix. Some of you may still be using the beta version of Android Studio (which is full of bugs). Update it to 1.0+ and you should be okay.

http://stackoverflow.com/questions/26244998/androidmanifest-in-androidtest-directory-being-ignored

It seems like the android manifest used to be ignored in earlier versions.

Wait. Never mind that. That may still fix it though. I found another method. Click on File>Invalidate Caches and Restart

Android Studio will restart after that but you should be okay then
