Ich wollte die Navigationsschublade von Google unter http://developer.android.com/training/implementing-navigation/nav-drawer.html#top angegeben implementieren.Android - Implementieren Navigationsschublade in Android 2.2 +
Also habe ich die Probe von dort heruntergeladen und die appcompat-Bibliothek von v7 Support-Bibliothek verwendet.
Geändert erweitert Aktivität für MainActivity, um ActionBarActivity zu erweitern. Und alles verändert, die Fehler erfordern min API Stufe von 11 auf seiner Support-Bibliothek Äquivalent (getActionBar() ---> getSupportActionBar(), getFragmentmanger() zu getsupportFragmentmanager()) gab
Aber jetzt meine App stürzt bei die erste Zeile super.onCreate(savedInstanceState); in der onCreate() -Methode.
Wenn ich versuche, es gibt mir den Fehler zu debuggen, dass Quelle nicht gefunden und öffnet die ActivityThread.performLaunchActivity(ActivityThread$ActivityClientRecord, Intent) line: 1953

/**
* This example illustrates a common usage of the DrawerLayout widget
* in the Android support library.
* <p/>
* <p>When a navigation (left) drawer is present, the host activity should detect presses of
* the action bar's Up affordance as a signal to open and close the navigation drawer. The
* ActionBarDrawerToggle facilitates this behavior.
* Items within the drawer should fall into one of two categories:</p>
* <p/>
* <ul>
* <li><strong>View switches</strong>. A view switch follows the same basic policies as
* list or tab navigation in that a view switch does not create navigation history.
* This pattern should only be used at the root activity of a task, leaving some form
* of Up navigation active for activities further down the navigation hierarchy.</li>
* <li><strong>Selective Up</strong>. The drawer allows the user to choose an alternate
* parent for Up navigation. This allows a user to jump across an app's navigation
* hierarchy at will. The application should treat this as it treats Up navigation from
* a different task, replacing the current task stack using TaskStackBuilder or similar.
* This is the only form of navigation drawer that should be used outside of the root
* activity of a task.</li>
* </ul>
* <p/>
* <p>Right side drawers should be used for actions, not navigation. This follows the pattern
* established by the Action Bar that navigation should be to the left and actions to the right.
* An action should be an operation performed on the current contents of the window,
* for example enabling or disabling a data overlay on top of the current content.</p>

Danke, es hat mir aber geholfen Die App stürzt immer noch auf Android 2.2 ab. Ich habe den Logcat dafür aktualisiert. Bitte helfen Sie. –
Ich habe meine Antwort aktualisiert, bitte überprüfe sie, lass es mich wissen, wenn es für dich funktioniert. –
Ich habe meine XML-Dateien aktualisiert. Die Dateien, die Fehler in Logcat geben, sind nicht vorhanden, und ich sehe nirgendwo, dass sie in dem Code verwiesen werden. Irgendwelche Vorschläge? –
