解组android.support.v7.widget.Toolbar$SavedState时的ClassNotFoundException
提问于 2015-05-04 19:11:08
我在我的Android崩溃报告中看到以下错误：

at dalvik.system.NativeStart.main(NativeStart.java)它似乎在恢复活动时间歇性地发生。我不会在任何代码中直接访问SavedState类。
编辑:我的活动的布局Xml是
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:orientation="vertical">
<include layout="@layout/toolbar" />
....而工具栏XML是
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>在我的活动的onCreate中，我做到了
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_txn);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
localBroadcastManager = LocalBroadcastManager.getInstance(getApplicationContext());
mResources = getResources();
if (savedInstanceState != null) {
long id = savedInstanceState.getLong(STA_TXN_ID);
...
} else {
... read fresh
}
mDateTV = (TextView) findViewById(R.id.ASTVDate);
mDayTV = (TextView) findViewById(R.id.ASTVDay);
mCatName = (TextView) findViewById(R.id.ASTVCatName);
mMonthTV = (TextView) findViewById(R.id.ASTVMonth);
....
Calendar c = java.util.Calendar.getInstance();
c.setTime(txn.getTxnDate());
mDateTV.setText("" + c.get(Calendar.DAY_OF_MONTH));
mDayTV.setText(c.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.LONG, Locale.US));
mMonthTV.setText(c.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.US));
}我一直在使用appcompat-v7:22.1.1，是的，我在proguard之后得到了这些错误。

根据AAverin的消息来源Google Issue 196430，构建工具版本24包括一个修复。
例如，在build.gradle中更改构建工具版本：
buildToolsVersion "24.0.0"或者，通过捕获(在我的特定情况下)来防止崩溃：
try {
// Temporary fix for crash issue
mapView.onCreate(savedInstanceState);
} catch (Throwable t) {
t.printStackTrace();

我在传递两个寓言对象时遇到了这个问题，一个是类型A，另一个是类型B，其中包含类型A对象。我在parceable数组中传递了它们，我的问题就解决了。
