Android Studio Tips INotify Solutions _android

Objective

INotify will set "watch handle" for all folders within the project. Unfortunately, the limit for the Linux default watch handle does not meet the actual engineering size, and exceeding the limit will force the IntelliJ to rescan the recursive tree of the project directory (which can be time-consuming).

In order to avoid this problem, we recommend to modify the limit of watches (generally 521k), the following is the specific steps to resolve.

Problem Description:

Using Android Studio to import AOSP source code and indexing, the IDE may throw a warning "Kernel inotify Watch Limit reached" in the upper-right corner.

Workaround:

Open the /etc/sysctl.conf file and add a sentence at the end of the file:

Fs.inotify.max_user_watches = 524288

Use the following command to make the modification effective:

sudo sysctl-p

Then restart your Android studio.
