Android studio takes too much memory

Question

I had installed Android Studio 1 0 RC 2  I have 4GB of RAM installed  but after starting Android Studio and launching Android Emulator  more than 90  of physical memory has been used by only these two  Is there is any way to reduce this memory use  Due to this memory issue  I can t open other applications at the same time

Open below mention path on your system and delete all your avd's (Virtual devices: Emulator)

C:\Users{Username}.android\avd

Note: - Deleting Emulator only from android studio will not delete all the spaces grab by their avd's. So delete all avd's from above given path and then create new emulator, if you needed.

You can speed up your  Eclipse or Android Studio work  you just follow these    Use open single project at a time  clean your project after running your app in emulator every time use mobile external device instead of emulator  don t close emulator after using once  use same emulator for running app each time Disable VCS by using File- Settings- Plugins and disable the following things   1 CVS Integration 2 Git Integration 3 GitHub 4 Google Cloud Tools for Android Studio 5 Subversion Integration   I am also using Android Studio with 4-GB installed main memory but following these statements really boost my Android Studio performance

Android Studio has recently published an official guide for low-memory machines  Guide  If you are running Android Studio on a machine with less than the recommended specifications  see System Requirements   you can customize the IDE to improve performance on your machine  as follows    Reduce the maximum heap size available to Android Studio  Reduce the maximum heap size for Android Studio to 512Mb  Update Gradle and the Android plugin for Gradle  Update to the latest versions of Gradle and the Android plugin for Gradle to ensure you are taking advantage of the latest improvements for performance  Enable Power Save Mode  Enabling Power Save Mode turns off a number of memory- and battery-intensive background operations  including error highlighting and on-the-fly inspections  autopopup code completion  and automatic incremental background compilation  To turn on Power Save Mode  click File   Power Save Mode  Disable unnecessary lint checks  To change which lint checks Android Studio runs on your code  proceed as follows  Click File   Settings  on a Mac  Android Studio   Preferences  to open the Settings dialog In the left pane  expand the Editor section and click Inspections  Click the checkboxes to select or deselect lint checks as appropriate for your project  Click Apply or OK to save your changes  Debug on a physical device  Debugging on an emulator uses more memory than debugging on a physical device  so you can improve overall performance for Android Studio by debugging on a physical device  Include only necessary Google Play Services as dependencies  Including Google Play Services as dependencies in your project increases the amount of memory necessary  Only include necessary dependencies to improve memory usage and performance  For more information  see Add Google Play Services to Your Project  Reduce the maximum heap size available for DEX file compilation  Set the javaMaxHeapSize for DEX file compilation to 200m  For more information  see Improve build times by configuring DEX resources  Do not enable parallel compilation  Android Studio can compile independent modules in parallel  but if you have a low-memory system you should not turn on this feature  To check this setting  proceed as follows  Click File   Settings  on a Mac  Android Studio   Preferences  to open the Settings dialog  In the left pane  expand Build  Execution  Deployment and then click Compiler  Ensure that the Compile independent modules in parallel option is unchecked If you have made a change  click Apply or OK for your change to take effect  Turn on Offline Mode for Gradle  If you have limited bandwitch  turn on Offline Mode to prevent Gradle from attempting to download missing dependencies during your build  When Offline Mode is on  Gradle will issue a build failure if you are missing any dependencies  instead of attempting to download them  To turn on Offline Mode  proceed as follows    Click File   Settings  on a Mac  Android Studio   Preferences  to open the Settings dialog  In the left pane  expand Build  Execution  Deployment and then click Gradle  Under Global Gradle settings  check the Offline work checkbox  Click Apply or OK for your changes to take effect

I have used all of Sam s recommendations above  but I found that the VM command line options are no longer supported as described   I received an error when used   As an alternative  I was able to reduce gradle dramatically by adding the following line to the  gradle properties  file   org gradle jvmargs -Xms512m -Xmx1024m   As of A S  ver 1 3  the file is located in the same folder level as  gradle build    The above configuration is a  memory stack  of 512 meg  and  memory heap  of 1024 meg   I tested this on a small project  using settings where both memory sizes were set to 256 meg   It limited the JVM sizes as expected   In all my tests  I restarted A S  to force the JVM to restart   Hopefully  this will save others dealing with this issue from getting those  Get yourself a better computer  responses    -

In my case  there were two main sources of memory hogging  the IDE and Gradle   Android Studio  up to 1 5GB   The IDE s JVM is configured to have a max heap size  You can see this in the lower-right corner of the main interface     You can reduce this by editing the memory-related settings in the  vmoptions file  For example  I changed my max heap size to 512MB   -Xmx512m   Unfortunately  I found that lowering this value increases the frequency of Android Studio temporarily freezing  perhaps to do its garbage collection   Gradle  up to 1 5GB   Gradle can also use a lot of RAM after developing for a while  Windows just shows it as Java TM  Platform SE Binary     You can fix this by changing the Gradle JVM options  You can do this on a per-user basis by editing gradle properties    Open the gradle properties file  creating it if it doesn t exist    Windows   USERPROFILE   gradle gradle properties Linux Mac     gradle gradle properties  Update the org gradle jvmargs property  creating it if necessary  I set mine to this   org gradle jvmargs -Xmx256m -XX MaxPermSize 256m -XX  HeapDumpOnOutOfMemoryError -Dfile encoding UTF-8    I haven t noticed any difference in build performance for my small project with the max heap size set to 256MB  -Xmx256m    Note that you might need to restart Android Studio so the old Gradle process is killed  otherwise you might end up with both running at the same time   Emulator  Regarding the emulator taking up a lot of your RAM  your screenshot shows it taking about 800MB  You can choose how much RAM to allocate to the emulator    Edit the AVD Press Show Advanced Settings Reduce the value of RAM
