I am using AOSP android 11 in the RPi4. I have enabled the i2c in config.txt using the param dtparam=i2c_arm=on.

The i2c is showing in the /sys/bus/i2c/devices/i2c-1 but /dev/i2c is not listing in the dev folder.

I want to access the APDS-9960 gesture sensor in AOSP. Please suggest some solution.

Finally, I got it.

Open the config file bcm2711_defconfig under the kernel path kernel/arpi/arch/arm64/configs and change the config value CONFIG_I2C_CHARDEV=y. This will enable the dev/i2c.
