Android E/Parcel:解组时找不到类(仅限三星Tab3)

我一直无法解决为什么会出现这种错误,并且只能在运行4.4.2的三星Tab3设备上解决？它发生在我的MainActivity启动另一个Activity时,并在intent中传递一个Parcelable类,如下所示:

    private void debugTest(TestParcel cfgOptions){
        TestParcel cfgOptions = new TestParcel();
        cfgOptions.setValue(15); //just to verify

        Intent intent = new Intent(MainActivity.this, TestActivity.class);
        intent.putExtra("cfgOptions", cfgOptions);
        startActivityForResult(intent, DBG_TEST);
    }

Run Code Online (Sandbox Code Playgroud)

TestActivity获取可分配的数据,如下所示:

升级到Android Studio 2.3后,获取"package android.support.multidex"不存在

我昨天从Android Studio 2.2.3更新到Android Studio 2.3,我遇到了以下两个问题:

更新后,默认情况下安装了Gradle 3.2,但同步我的项目不起作用,我不断收到错误消息"需要Gradle 3.3".使用默认的Gradle包装器不起作用.解决此问题的唯一方法是手动下载Gradle 3.3并指向构建设置中的目录.
在运行我的项目时,我不断收到涉及我的BaseApplication课程的一系列错误 MultiDexApplication.错误是这样的:

Error:(19, 62) error: package android.support.multidex does not exist

我无法解决此错误.我有buildToolsVersion '25.0.2',并且我的项目在升级到Android Studio 2.3之前已经编译并正常运行.任何人都可以帮我解决这个问题吗？
