Android Studio - How to increase Allocated Heap Size

I looked at my Environment Variables and had a System Variable called _JAVA_OPTIONS with the value -Xms256m -Xmx512m, after changing this to -Xms256m -Xmx1024m the max heap size increased accordingly.

Android studio warning this IDE is Runing in low memory, also android studio keeps not reponding

4 GB RAM is not a lot for Android studio..8 GB or above is good very good.6 GB is kind of just ok.This is my experince.

What you can do is to improve the Android studio's perfoemance is this :

1.Click File > Settings from the menu bar (or Android Studio > Preferences on macOS).
2.Click Appearance & Behavior > System Settings > Memory Settings.
Adjust the heap sizes to match your desired amounts.

Click Apply.

If you changed the heap size for the IDE, you must restart Android Studio before the new memory settings are applied.

Note : Allocating too much memory can degrade performance.but you can increase heap size more with improved performance only if you have a larger RAM or available larger RAM.SO, while you can increase heap size, don't increase a lot.

How to increase heap size of an android application?

You can use android:largeHeap="true" to request a larger heap size, but this will not work on any pre Honeycomb devices. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above.

The only way to have as large a limit as possible is to do memory intensive tasks via the NDK, as the NDK does not impose memory limits like the SDK.

Alternatively, you could only load the part of the model that is currently in view, and load the rest as you need it, while removing the unused parts from memory. However, this may not be possible, depending on your app.
