自从我两天前将手机（三星Galaxy S7）更新到新的Android 7.0后，我在运行我的应用时偶尔出现错误。当Activity_C与startActivity：
java.lang.RuntimeException: Unable to start activity ComponentInfo{de.my.app/de.my.app.gui.Activity_C}: java.lang.IllegalStateException: Bad magic number for Bundle: 0x620061
（下面的完整堆栈跟踪）
Activity_C继承自Activity_B，Activity_A本身继承自Activity_A。 AppCompatActivity将android.support.v7.app扩展为包onCreate。
活动A，B和C有protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
方法，其开头如下：
savedInstanceState发生错误时，null是默认startActivity。 context.startActivity(new Intent(getActivity(), Activity_C.class));调用始终相同（01-27 21:36:45.241 9953-9953/de.my.app E/AndroidRuntime: FATAL EXCEPTION: main

）且来自同一活动。
我搜索了几个小时，但没有发现任何有用的东西。我不是新手，也不是专家;但它看起来对我来说问题不在于我的活动，而在于android系统的东西。
我现在使用最新的sdk（25）和相应的支持包（25.1.0），但错误也发生在我之前使用过的sdk v23上。在运行Android 5或6的其他设备上，一切仍然正常。
有人知道为什么会出现这个问题以及如何处理它？</ p>
