我在我的 Android 崩溃报告中看到以下错误：

恢复活动时，它似乎间歇性地发生。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" />
....

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 我做

@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));
}

而且我一直在使用 appcompat-v7:22.1.1，是的，我在 proguard 之后遇到了这些错误。

看起来下面的问题正是关于它： https ://code.google.com/p/android/issues/detail?id=196430

根据 Averin 的消息来源，Google Issue 196430，构建工具版本 24 包含一个修复程序。

EG 更改 build.gradle 中的构建工具版本：

buildToolsVersion "24.0.0"

或者，通过捕获（在我的特定情况下）防止崩溃：

try {
    // Temporary fix for crash issue
    mapView.onCreate(savedInstanceState);
} catch (Throwable t) {
    t.printStackTrace();
}

当我传递 2 个可比喻的对象时，我遇到了这个问题，其中一个是 A 型，另一个是 B 型，包含 A 型对象。我以parceable数组的形式传递了它们，我的问题得到了解决。
