Przeczytałem również artykuł sugerujący rozwiązanie (java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV14). Sugeruje, żebym dodał następujące w pliku build.gradle.

compile 'com.android.support:appcompat-v7:22.2.0' 

Właściwie to było już w pliku i wygląda na to, że nie jest to oryginalny problem. Oto mój plik build.gradle.

dependencies { 
compile fileTree(dir: 'libs', include: ['*.jar']) 
compile 'com.android.support:appcompat-v7:22.2.0' 
compile project(':volley') 
compile project(':android-support-v4') 
} 

W przypadku trzeba spojrzeć na mojego kodu, tutaj jest mój kod, który jest przyczyną NoClassDefFoundError.

public class MainScreenActivity extends AppCompatActivity { 
private DrawerLayout mDrawerLayout; 
private ListView mDrawerList; 
private ActionBarDrawerToggle mDrawerToggle; 

private CharSequence mDrawerTitle; 

private CharSequence mTitle; 

private String[] navMenuTitles; 
private TypedArray navMenuIcons; 

private ArrayList<NavDrawerItem> navDrawerItems; 
private NavDrawerListAdapter adapter; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_mainscreen); 

    mTitle = mDrawerTitle = getTitle(); 

    navMenuTitles = getResources().getStringArray(R.array.drawermenu_items); 

    navMenuIcons = getResources() 
      .obtainTypedArray(R.array.drawermenu_icons); 

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    mDrawerList = (ListView) findViewById(R.id.list_slidermenu); 

    navDrawerItems = new ArrayList<NavDrawerItem>(); 

    navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1))); 
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1))); 
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1))); 
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1), true, "22")); 
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1))); 
    navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1), true, "50+")); 


    navMenuIcons.recycle(); 

    mDrawerList.setOnItemClickListener(new SlideMenuClickListener()); 

    adapter = new NavDrawerListAdapter(getApplicationContext(), 
      navDrawerItems); 
    mDrawerList.setAdapter(adapter); 

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.app_name, R.string.app_name) { 
     public void onDrawerClosed(View view) { 
      getSupportActionBar().setTitle(mTitle); 
      invalidateOptionsMenu(); 
     } 

     public void onDrawerOpened(View drawerView) { 
      getSupportActionBar().setTitle(mDrawerTitle); 
      invalidateOptionsMenu(); 
     } 
    }; 
    mDrawerLayout.setDrawerListener(mDrawerToggle); 

    if (savedInstanceState == null) { 
     displayView(0); 
    } 
} 

Oto dodatkowy dziennik błędów. Może być wskazówka dotycząca rozwiązania.

i tutaj jest plik xml dla działania.

<?xml version="1.0" encoding="UTF-8"?> 
<android.support.v4.widget.DrawerLayout

android:id="@+id/drawer_layout"

Answer 1

może istnieć konflikt ze swoimi zależnościami

spróbuj usunąć

compile project(':android-support-v4') 

Answer 2

Miałem ten sam błąd i całkowicie umożliwiając multidex pracował dla mnie. tutaj jest to, co zrobiłem w Gradle i oczywistych plików

android { 
compileSdkVersion 21 
buildToolsVersion "21.1.0" 

defaultConfig { 
    ... 
    minSdkVersion 14 
    targetSdkVersion 21 
    ... 

    // Enabling multidex support. 
    multiDexEnabled true 
} 
... 
} 

dependencies { 
compile 'com.android.support:multidex:1.0.0' 
} 

również w moim pliku manifestu, muszę dodać klasę MultiDexApplication z multidex biblioteki wsparcia z elementem aplikacji jak ten

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.android.multidex.myapplication"> 
    <application 
     ... 
     android:name="android.support.multidex.MultiDexApplication"> 
     ... 
    </application> 
</manifest>
