我将Nexus 5X更新为Android N，现在当我安装应用程序（调试或发布）时，我在每个包含Bundle的屏幕转换中都会收到TransactionTooLargeException。 该应用程序正在处理所有其他设备。 在PlayStore上的旧应用程序和大多数相同的代码正在使用Nexus 5X。 有人有同样的问题吗？

The app is working on all other devices. The old app that is on PlayStore and has mostly same code is working on Nexus 5X. Is anyone having the same issue?

最后，我的问题是在保存在事件中的东西，而不是发送到下一个活动的东西。 我删除了我无法控制对象大小（网络响应）的所有保存，现在它正在运行。
更新：
为了保存大量数据，Google建议使用保留实例的Fragment来执行此操作。 想法是创建空的片段，而不需要具有所有必需字段的视图，否则将保存在Bundle中。 添加setRetainInstance(true); 到Fragment的onCreate方法。 然后将数据保存在Activity onDestroy上的Fragment中，并将它们加载到Create上。 这是一个Activity的例子：
public class MyActivity extends Activity { private DataFragment dataFragment; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // find the retained fragment on activity restarts FragmentManager fm = getFragmentManager(); dataFragment = (DataFragment) fm.findFragmentByTag(“data”); // create the fragment and data the first time if (dataFragment == null) { // add the fragment dataFragment = new DataFragment(); fm.beginTransaction().add(dataFragment, “data”).commit(); // load the data from the web dataFragment.setData(loadMyData()); } // the data is available in dataFragment.getData() ... } @Override public void onDestroy() { super.onDestroy(); // store the data in the fragment dataFragment.setData(collectMyLoadedData()); } }和片段的例子：
public class DataFragment extends Fragment { // data object we want to retain private MyDataObject data; // this method is only called once for this fragment @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // retain this fragment setRetainInstance(true); } public void setData(MyDataObject data) { this.data = data; } public MyDataObject getData() { return data; } }更多关于它，你可以在这里阅读。
At the end, my problem was with things that were being saved onSaveInstance, and not with things that were being sent to next activity. I removed all saves where I can't control a size of objects (network responses), and now it's working.
Update:
To preserve big chunks of data, Google is suggesting to do it with Fragment that retains instance. Idea is to create empty Fragment without a view with all necessary fields, that would otherwise be saved in Bundle. Add setRetainInstance(true); to Fragment's onCreate method. And then save data in Fragment on Activity's onDestroy and load them onCreate. Here is an example of Activity:
public class MyActivity extends Activity { private DataFragment dataFragment; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // find the retained fragment on activity restarts FragmentManager fm = getFragmentManager(); dataFragment = (DataFragment) fm.findFragmentByTag(“data”); // create the fragment and data the first time if (dataFragment == null) { // add the fragment dataFragment = new DataFragment(); fm.beginTransaction().add(dataFragment, “data”).commit(); // load the data from the web dataFragment.setData(loadMyData()); } // the data is available in dataFragment.getData() ... } @Override public void onDestroy() { super.onDestroy(); // store the data in the fragment dataFragment.setData(collectMyLoadedData()); } }And example of Fragment:
public class DataFragment extends Fragment { // data object we want to retain private MyDataObject data; // this method is only called once for this fragment @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // retain this fragment setRetainInstance(true); } public void setData(MyDataObject data) { this.data = data; } public MyDataObject getData() { return data; } }More about it, you can read here.
