Preliminary Note:

Pre-configuration (with or without matching)

• View execution memory and allocated memory

Notice:

No matter how to optimize the compilation speed, we need to restart As to take effect

Optimization method

Method 1 : Memory allocation (the size of the internal allocation depends on your computer configuration, the general computer configuration can be set as follows)

step:

• Modify the memory allocation of AndroidStudio

• Modify the data in the studio64.exe.vmoptions file (friendly reminder: you can rename the file suffix to meet the needs of modification, remember to change it back after modification!)

Parameter introduction :

-Xms1024m //JVM启动的起始堆内存
-Xmx4096m //AndroidStudio能使用的最大heap内存
-XX:MaxPermSize=1024m //最大的Permanent generation大小。存放的事类本身（不是对象），以及方法，一些固定的字符串等等。
-XX:ReservedCodeCacheSize=512m //设置JIT java compiler在compile的时候的最大代码缓存
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=300

This is the modified parameter map:

Modified parameter code:

-Xms1024m
-Xmx2048m
-XX:ReservedCodeCacheSize=1024m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djna.nosys=true
-Djna.boot.library.path=

Precautions:

If you modify it according to the above picture and the compilation speed does not improve after restarting As, then please follow the picture below to see if you do this!

• User directory, view the corresponding version of As
  

• Check if there is this file, if so, modify it~
