我今天刚开始使用Roboguice，跟随Wiki https://github.com/roboguice/roboguice/wiki/Your-First-View-Injection，当我创建一个新的App时，示例工作正常，但是当我尝试在我现有的App上集成Roboguice时，它在运行时给出了NoClassDefFoundError
这是我的MainActivity。

// Set a Toolbar to replace the ActionBar.

setSupportActionBar(toolbar);
// Find our drawer view
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
//setupDrawerContent(mDrawer);
drawerToggle = setupDrawerToggle();
// Tie DrawerLayout events to the ActionBarToggle
mDrawer.setDrawerListener(drawerToggle);
// Set the menu icon instead of the launcher icon.
final ActionBar ab = getSupportActionBar();
ab.setHomeAsUpIndicator(R.drawable.ic_navigation_drawer);
ab.setDisplayHomeAsUpEnabled(true);
NavigationView navigationView = (NavigationView) findViewById(R.id.nvView);
if (navigationView != null) {
setupDrawerContent(navigationView);
}
}
private ActionBarDrawerToggle setupDrawerToggle() {
return new ActionBarDrawerToggle(this, mDrawer, toolbar, R.string.drawer_open, R.string.drawer_close);
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(

selectDrawerItem(menuItem);
return true;
}
});
}
public void selectDrawerItem(MenuItem menuItem) {
//Handles Menu Drawer Items
}
public void onFragmentInteraction(Uri uri){
//you can leave it empty
}
}
这是错误它抛出

它会在第69行

这是我的dex大小问题（通常你不能编译超过65k函数的dex，这可以通过在你的gradle脚本中使用启用multi-dex来解决）。
尝试启用multi-dex并查看它是否有帮助。
这是一个链接 - http://developer.android.com/tools/building/multidex.html。
祝你好运。答案 1 :(得分：0)
Roboguice现已弃用。您可以改用Toothpick。
