Just remove all the folders named AndroidStudioPreview  On Windows   Go to your User Folder - on Windows 7 8 this would be    SYSDRIVE   Users your username   ex  C  Users JohnDoe   In this folder there should be a folder called  AndroidStudioPreview  On Mac OS X  Remove these files     Library Application Support AndroidStudioPreview     Library Caches AndroidStudioPreview     Library Logs AndroidStudioPreview     Library Preferences AndroidStudioPreview

There is a power saver mode in android studio if accidentally you click on that it will disable code analysis which will reduce the battery consumption and performance will also increase but it will not detect any errors and do auto complete operations   To disable power saver mode  - Go to File Menu of Studio - Uncheck The Power Saver Mode   In your IDE code analysis will be shown using an eye symbol at the right corner of your android studio   If Green means it is enabled and there is no error in your code  If Red Means It is enabled but there are few errors in your code  If It is white or blur then code analysis is disabled

The file size  2561270 bytes  exceeds configured limit  2560000 bytes   Code insight features are not available      Had this issue for days with none of these proposed solutions working before eventually getting this message in yellow under the tabs after adding a line of code  Removing the line of code eliminated the message but not the issue  There appears to be a code size window where you lose insight features but don t get this message  at least for me  Once you go over a certain point the message finally pops up  The suggested solution in a different thread for this issue was to edit  Help Edit Custom Properties  to increase the configured limit  but just opening this brought up a dialogue asking if I wanted to create an  idea properties  folder so I decided not to risk that approach over eventually cutting the file size

Solution  Try disabling  File -  Power Save Mode  in Android Studio  Beta  0 8 14 - Mac OS X  On windows  the option can be at some other place     I had the same problem then I recalled that while exploring the new android studio  I switched on the  File -  Power Save Mode  to see what it does   I disabled the power save mode and all those intelligent features were back   It turned out that in Power Save Mode  Android Studio switches off the modules responsible for features like Smart Code Completion and Code Analysis

I have not run into this problem personally  but try checking the following settings  File -  Settings or Alt F7    Project Settings  name  Inspections - ensure that Android and Android Lint is checked  or alternately just set it back to default using the dropdown box at the top   IDE Settings Editor -  Code Completion - ensure the Autopopup code completion is checked  and check the rest of the settings based on your preference
