Prevent DrawerLayout from opening the right side when closing the left side?

I have a DrawerLayout with two drawers, one on the left and one on the right side.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawerLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <fragment        
        android:id="@+id/mainFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <fragment
        android:id="@+id/leftFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="left|start"/>

    <fragment
        android:id="@+id/rightFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="right|end"/>

</android.support.v4.widget.DrawerLayout>

The problem is that sometimes when I swipe left to close the left drawer, it also opens the right one.

Is there any way to prevent this from happening? I'm thinking maybe I could block the opposite side from opening until both sides have been closed for at least X milliseconds or something, but I have no clue how to go about it.

Lock and UnLock the drawer from opening and closing based on drawer status

Code for LeftSide Drawer

mDrawerLayoutLeft.addDrawerListener(new DrawerLayout.DrawerListener() {

        @Override
        public void onDrawerOpened(View drawerView) {
            //lock the right side drawer when open the left drawer
            mDrawerLayoutRight.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
        }

        @Override
        public void onDrawerClosed(View drawerView) {
             //unlock the right side drawer when close the left  drawer
            mDrawerLayoutRight.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
        }

    });

Code for right side drawer

mDrawerLayoutRight.addDrawerListener(new DrawerLayout.DrawerListener() {

        @Override
        public void onDrawerOpened(View drawerView) {
            //lock the left side drawer when open the right  drawer
            mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
        }

        @Override
        public void onDrawerClosed(View drawerView) {
             //unlock the left side drawer when close the right drawer
            mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
        }

    });

There is other property for lock drawerLayout with gravity.

Lock and unlock with Gravity.START

UNLOCK

mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED, Gravity.START);

LOCK

mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.START);

Lock and unlock with Gravity.END

UNLOCK

mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED, Gravity.END);

LOCK

mDrawerLayoutLeft.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, Gravity.END);
