Android Studio: No view found for id (WebView fragment project) [duplicate]

Just wanted to share an issue that I have with a project that I am doing for a client.
Whenever I enter to my IntroActivity and press the button to take me to MenuActivity, it crashes.
Here is the error log:

Any help would be appreciated

I think I have found something.
fragmentManager.beginTransaction()
.replace(R.id.linear, fragment).commit();
As you see you try to replace the layout R.id.linear with your fragment. But the R.id.linear is the RelativeLayout you use in your fragment_menu.xml. You should replace the layout in your activity_menu.xml with the current fragment. So I would suggest:
fragmentManager.beginTransaction().replace(R.id.container, fragment).commit();
And in your activity_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ff0a393d">
<!-- Linearlayout to display Fragments -->
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:id="#+id/container">
EDIT:
For the new error: There is a problem with your memory. This often happens when ImageViews are filled by big ressources. So there is only one position where you use an ImageView:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_menu, container, false);
ImageView imagenView = (ImageView) rootView.findViewById(R.id.imageView1);
imagenView.setImageResource(imagen);
return rootView;
}
As you see, your imagenView is filled by the resource imagen
imagenView.setImageResource(imagen);
Probably you get the OutOfMemoryError there. As a solution, try this:
try {
imagenView.setImageResource(imagen);
} catch (OutOfMemoryError e) {
//fill your ImageView with something smaller .. maybe a smaller resolution
Log.e("PlaceholderFragment", "Error: OutOfMemoryError")
}
Check your imagen too, whether there is a high resolution needed.

Nullpointer exception - FragmentActivity

I have received a nullpointer exception error in my fragmentactivity.

Thanks in advance.

Since you are importing import android.support.v7.app.ActionBarActivity , I guess you should use
getSupportActionBar()
instead of
getActionBar()

Instead of
getActionBar().getThemedContext()
use this

Android app crashing with OnClickListener in fragment

I'm having a problem building my first App. I'm using Navigation drawer to switch between fragments. But when i choose OrderFragment from Navigation drawer, app crashes.
OrderFragment has only one button showing a toast when clicked, but the app crashes before the OrderFragment loads.

At first sight you should replace:
final Button send = (Button) getActivity().findViewById(R.id.send);
with:
final Button send = (Button) mView.findViewById(R.id.send);
R.id.send id is contained in the Fragment view mView.

Android: Navigation Drawer NullPointerException

I am using code from the developer website (http://developer.android.com/training/implementing-navigation/nav-drawer.html) to install a navigation drawer, however, I am getting a NullPointerException in this method:

menu xml

android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never"/>
</menu>

Your menu.xml has only one time with id= action_settings. You should add another menu item for search.
example:
You can use searchView
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="#string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />

The variable mDrawerList might not be initialised correctly. It could be null, thus causing the NullPointerException.

There is an error in your code. The stack trace shows that. And here's the relevant information
12-19 15:07:20.562: E/AndroidRuntime(1067): Caused by: java.lang.NullPointerException
12-19 15:07:20.562: E/AndroidRuntime(1067): at com.dhruv.sms.MainActivity.onCreate(MainActivity.java:80)
Line 80 shows mDrawerList being accessed. It's null

the error is in this part of your code
mDrawerList.setAdapter(adapter);
mDrawerList reference might be wrong or adapter is wrong

private ListView mDrawerList=new ListView();
You haven't initialized the ListView.
