自从两天前我将手机(三星 Galaxy S7)更新到新的 Android 7.0 后,我在运行我的应用程序时偶尔会出现错误。它有时会在开始时发生(平均每五次)Activity_C
with 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
其自身继承自Activity_A
。Activity_A
从AppCompatActivity
包中扩展android.support.v7.app
。
活动 A、B 和 C 有一个onCreate
这样开始的方法:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
当错误发生时,savedInstanceState
肯定是null
。startActivity
调用总是相同的 ( )context.startActivity(new Intent(getActivity(), Activity_C.class));
并且来自相同的活动。
我已经搜索了几个小时,但没有发现任何有用的东西。我不是新手,也不是专家;但在我看来,问题不在于我的活动,而在于 android 系统的东西。
我现在正在使用最新的 sdk (25) 和适当的支持包 (25.1.0),但我之前使用的 sdk v23 也会出现错误。在其他运行 Android 5 或 6 的设备上,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吗?
这是完整的堆栈跟踪:
