I agree with @Kaediil that android applications must work well while "Don't keep activities" option is checked.

Bu for some reason if you have to check "alwaysFinishActivities" value you can use code below;

/**
 * returns true if AlwaysFinishActivities option is enabled/checked
 */
private boolean isAlwaysFinishActivitiesOptionEnabled() {
    int alwaysFinishActivitiesInt = 0;
    if (Build.VERSION.SDK_INT >= 17) {
        alwaysFinishActivitiesInt = Settings.System.getInt(getApplicationContext().getContentResolver(), Settings.Global.ALWAYS_FINISH_ACTIVITIES, 0);
    } else {
        alwaysFinishActivitiesInt = Settings.System.getInt(getApplicationContext().getContentResolver(), Settings.System.ALWAYS_FINISH_ACTIVITIES, 0);
    }

    if (alwaysFinishActivitiesInt == 1) {
        return true;
    } else {
        return false;
    }
}

If alwaysFinishActivities option is checked and you want it to be unchecked;

You can direct user to "Settings -> Developer options" to uncheck that value. (This is better than to get extra scary permissions and set this value programatically)

/**
 * shows Settings -> Developer options screen
 */
private void showDeveloperOptionsScreen(){
    Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DEVELOPMENT_SETTINGS);
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
    startActivity(intent);
}
