Sembra accadere in modo intermittente quando si riprende un'attività. Non accedo direttamente alla classe SavedState in alcun codice.

EDIT: Xml Layout per la mia attività è

<?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" /> 
.... 

E XML barra degli strumenti è

<?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"/> 

E nella mia onCreate di attività che faccio

@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)); 
} 

E devo state usando appcompat-v7: 22.1.1 e sì I g e questi errori dopo proguard.

Answer 1

Sembra seguente problema è esattamente a questo proposito: https://code.google.com/p/android/issues/detail?id=196430

Answer 2

Secondo fonte di AAverin, Google Issue 196430, costruire strumenti versione 24 include una correzione.

E.G. cambiare la versione costruire strumenti in build.gradle:

buildToolsVersion "24.0.0" 

In alternativa, impedire gli arresti per la cattura (nel mio caso particolare):

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