Solution 1:

You may have gotten this error while attempting to run an Android application on an emulator or device using Android Studio. The most common cause of this error is simple as stated in this link: You have to manually unlock your Android Virtual Device by swiping the "lock" icon on the screen. Security measures prevent the emulator from letting you connect the debugger before doing this. Make sure also that you are running Android Studio version above 0.3.2 or the latest version. There was some issue reported in AS 0.3.2. You can update it from Help >Check for update.

Found this thread which states that it might be an issue with your emulator not with Android Studio. Maybe you are trying to install application before even the emulator started properly. Wait till the home screen appears in the emulator before trying to install any application.

Also try to install any apk in Emulator from command line

Steps to install

• Go to $Android_SDK_DIR\platform-tools, right click there keeping shift key pressed and Chose "Open Command Window here".
• Run command adb devices to make sure yout emulator is running properly. It will show all your running emulators.
• Now if emulators are showing properly, type the command adb install YOUR_FULL_APK_PATH , YOUR_FULL_APK_PATH is of any .apk file path in your system.

You need to wait for the emulator to full start which may take a few minutes. Once it is fully started (UI on the emulator will change), it should work. You will need to restart the app after the emulator is running and choose the running emulator when prompted. You can check on this bug report the full details.

Hope this helps!
