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:

Need more info, let me know
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.

Please how can i solve this problem of unable to instantiate activity? Thanks

What exceptions throws
java.lang.ClassNotFoundException: com.aa.slide.MainActivity
ClassNotFoundException occurs when class loader could not find the required class in class path . So , basically you should check your class path and add the class in the classpath.
Rebuild and Clean up your Project.Please check This SO Answer.
For your information,Since the version 22.1.0, the class ActionBarActivity is deprecated. You should use AppCompatActivity or Actvity . I hope it helps you .

Be sure that this is in your gradle file:
dependencies {
compile 'com.android.support:appcompat-v7:21.0.0'
}
The problem is that the dalvikVM can't find import android.support.v7.app.ActionBarActivity; which is the superclass of your MainActivity
You can see this in:
08-14 13:18:18.632: W/dalvikvm(12483): Unable to resolve superclass of Lcom/aa/slide/MainActivity; (11)

Try this in Manifest file:
**android:name=".MainActivity"**
<activity
android:name="com.aa.slide.MainActivity"
android:label="#string/app_name"
android:theme="#style/Theme.MyCompatTheme">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Hi I am new to Android stuff.Right now I'm following the tutorial given in developer.android.com/training/basics/firstapp/starting-activity.html and building my fist app.It was fine until I dealt with single activity.Later I have added second activity.When I click the button in first it should be directed to second activity.But on clicking first activity my app stops suddenly.Please help me.

You're making a silly error in the second activity code due to copy pasting:
DisplayMessageActivity:
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();
}
}
You're trying to add the PlaceholderFragment to the R.id.container, when the content view of the second activity is the TextView, which does NOT have the container, aka the layout specified by R.id.container does not exist in the second activity.
Remove these lines from the second activity and it should work.

You forgot to add the activity to the manifest I think...
<activity
android:name="DisplayMessageActivity"
android:label="#string/..." >
</activity>

Check your XML layout for MainActivity, you specify findViewById(R.id.edit_query) for your EditText which was never declared.
Add the stared line to your fragment_main.xml file
`<EditText
**android:id="#+id/edit_query**
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/edit_message"
android:layout_weight="1"/>`

Android start next activity fail

I'm developing an android app with a splash screen. I want another activity which is a tab swiper to be started soon after the splash screen and next go to the main activity.
When I run the following code, my splash screen works fine but then the app stops without showing the tabswiper or the main activity. How should I change my code to get it working? Any suggestions would be highly valued.
My main activity: MainActivity.java
package lk.sidadiya.sidadiya;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent i = new Intent(MainActivity.this, WelcomeScreen.class);
startActivity(i);
// close this activity
finish();
}
My tabswiper: WelcomeScreen.java
package lk.sidadiya.sidadiya;
import lk.sidadiya.tabswipe.adapter.TabsPagerAdapter;
import lk.sidadiya.sidadiya.R;
import android.app.ActionBar;
import android.app.ActionBar.Tab;

private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Top Rated", "Games", "Movies" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**

viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override

No view found for id 0x7f05003c (com.example.helloworld:id/container) for fragment PlaceholderFragment
The error is saying it cannot find the view with an id of container for the fragment placeholder to go into.
setContentView(R.layout.activity_seccond);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
This part of the code is the main problem. In the add() for the getSupportFragmentManager, it is saying to create the fragment and put it in a view with the id container. But the layout specified in setContentView does not have a view with an id of container. So there needs to be a layout file with a View (like a frame) with an id of container, so that when the fragment layout loads, it can go into that view.
Try adding a file to layouts called activity_frame_seccond.xml with:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Which is a frame with the id 'container'.
Change this line in Seccond.java:
setContentView(R.layout.activity_seccond);
for
setContentView(R.layout.activity_frame_seccond);
and see if that works.
With this code you are using the new file activity_frame_seccond.xml as the layout for the activity, and the first file activity_seccond.xml as the fragment that will put in the frame element (because it has the id container).
If this doesn't work let me know and I will have another look.

Check this line in your Fragment class :
View rootView = inflater.inflate(R.layout.activity_seccond,
container, false);
i think the Returned View is Null

Remove this line from your manifest
<activity
android:name="com.example.helloworld.Second"
android:label="#string/app_name" >
>
</activity>
and try

try in this way
#Override
public void onClick(View arg0) {
Intent intent = new Intent(this,Seccond.class);
startActivity(intent);
}
