How to modify the memory threshold under android source code

The method to modify the memory threshold under the android source code is as follows:

Step 1: First create a XXX.txt file and enter the following code:

#! /system/bin/sh

echo " 1536，2048，4096，6 144，8 192， 12288 " >/sys/module/lowmemorykiller/parameters/min free；

This code is based on the corresponding value of MFM configuration 3. This value has been used for several days and no problems have been found. Let's take this value as an example for the time being.

Then save, and change the saved XXX.txt file to 67-Jasonfix.

Use RE Manager to put this 67-Jasonfix file in system/etc/init.d (this folder is full of startup script settings.

Then change the permission to: Check All.

Step 2: modify install-recovery.sh (in the system/etc directory).

(1). Find the line where these scripts are located.

sh /system/etc/init.d/XXXXX

Corresponding connection

sh /system/etc/init.d/67-Jason

(2). Then find

echo A，B，C，D，E，F/sys/module/lowmemorykiller/parameters/min free

Delete this line and save it.
