Android java.lang.IllegalStateException-在onSaveInstanceState之后无法执行此操作

我从fabric.io收到以下崩溃报告，主要是在我添加了可从我的幻灯片菜单加载到我的应用程序的设置活动之后：

发布pendingRunnable的代码最近没有更改，但它开始接收异常

这是我的MainActivity.java

关于此问题的原因，您有什么想法吗？

尝试第一个setContentViewR.layout.activity\u main；而不是执行你的行动

@Override
        protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            this.myAppDatabaseHandler= MyAppDatabaseHandler.getInstance(this);
            defaultPrefs = PreferenceManager.getDefaultSharedPreferences(this);

            sharedpreferences = getSharedPreferences(MyAppConstants.PREFERENCES, Context.MODE_PRIVATE);

你有什么理由认为这样可以解决问题吗？

@Override
        protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            this.myAppDatabaseHandler= MyAppDatabaseHandler.getInstance(this);
            defaultPrefs = PreferenceManager.getDefaultSharedPreferences(this);

            sharedpreferences = getSharedPreferences(MyAppConstants.PREFERENCES, Context.MODE_PRIVATE);
