Android Studio Webview in a Fragment shows nothing and empty

I wish to implement a webview in the fragment_home_screen without covering the BottomNavigationView. However, even I followed everything on an online tutorial by setting up the webview in the Fragment_Home.java onCreateView() method. Nothing has showed up. I tried adding a button in the fragment_home_screen.xml to ensure the fragment DID showed up. It ended up showing the BUTTON ONLY.
I have been trying to fix this issues for hours and still couldn't figuring what's wrong with my code. Got any idea?

I tried your code and it works fine you just need to comment out some code in Fragment_Home.java as below:
#Override
public View onCreateView(....){
.....
..........
//remove or comment this part.
// myWebView.setWebViewClient(new SSLWebViewClient());

}

Map Class's onCreate() and onMapReady() functions never ran

I've created a basic Android app that is intended to have a map with a hamburger drawer on-top of that. Each hamburger menu option will run object methods on the GoogleMap object.
The issue is that while the hamburger drawer is created and works, the map's fragment is placed in the correct place, the onCreate and subsequently onMapReady functions in MainActivity are not running meaning the GoogleMap object is never made. I added some print statements to these functions to make sure and they are never printed.
I've got two classes, HamburgerDrawer.java and MainActivity.java.
HamburgerDrawer.java:

LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
I have multiple layout xml files to implement the hamburger menu, although the relevant one which contains the content for the drawer is here:
content_hamburger_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:id="#+id/content_hamburger_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.vanleusen.brighthelp.HamburgerDrawer"
tools:showIn="#layout/app_bar_hamburger_drawer">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<view
android:id="#+id/myview"
android:layout_width="match_parent"
android:layout_height="fill_parent"
class="android.view.View" />
</FrameLayout>
</RelativeLayout>
And finally I've heard this may be connected to my AndroidManifest although I tried some corrections nothing seemed to work for me, I included this below:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

I'd highly appreciate it if someone could help me work out why my map's onCreate and onMapReady functions are not being executed.

I think you are not calling MainActivity class from anywhere that's why this problem is coming.Please call it from HamburgerDrawer class in onCreate method or any clicklistener.
Intent a=new Intent(getApplicationContext,MainActivity.class);
startActivity(a);

My application won't change launch activity

I have tried to change the launch activity but am met with a blank screen saying "method" (which is pulled from #new_name string).
I tried to change it so that MainMenu would launch instead of activity_main

LogCat won't show anything at all for some reason. I'll see if I can figure out why and update with that.

You need to change this
protected void onCreate11(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
}
to
Button button,button1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
button = (Button) findViewById(R.id.button9);
button1 = (Button) findViewById(R.id.button1);
addListenerOnButtonNews();
addListenerOnButtonGPS()
}
Also change to
public void addListenerOnButtonNews() {
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), NewActivity.class);
startActivity(intent);
}
});
}
public void addListenerOnButtonGPS() {
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
}});
}

Trying to get a brand new android project to work with SlidingMenu (jfeinstein10) and ActionbarSherlock

I created a brand new android project and added SherlockActionBar and SlidingMenu to it.
I thought that i had copied everything from the example file but it still doesn't work. It shows my main fragment but the menu doesn't show at all when i click on the icon.
What am i missing??
Here are the classes and XML. Project is empty except for these classes/xml files.
Class 1 (Main activity):
import android.os.Bundle;
import com.slidingmenu.lib.SlidingMenu;
import com.slidingmenu.lib.app.SlidingFragmentActivity;
public class Main extends SlidingFragmentActivity {
protected MenuFragment mFrag;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mFrag = new MenuFragment();
setContentView(R.layout.activity_main);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.content_frame, new SectionOneFragment())
.commit();
// set the Behind View
setBehindContentView(R.layout.activity_menu);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.menu_frame, mFrag)
.commit();
// customize the SlidingMenu
SlidingMenu sm = getSlidingMenu();
sm.setMode(SlidingMenu.LEFT);
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setShadowDrawable(R.drawable.shadow);
sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
sm.setFadeDegree(0.35f);
sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setSlidingActionBarEnabled(false);
}
}
Class 2 (Menu fragment):
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class MenuFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_menu, null);
}
}
Class 3 (SectionOne fragment)
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class SectionOneFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
return inflater.inflate(R.layout.fragment_main, null);
}
}
Xml 1 (res->layout->activity_main.xml):
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Xml 2 (res->layout->activity_menu.xml):
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/menu_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Xml 3 (res->layout->fragment_main.xml):
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="#string/hello_world"
android:textColor="#ff00ff"
tools:context=".Main" />
Xml 4 (res->layout->fragment_menu.xml):
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="TEST"
android:textColor="#00ff00" />
Manifest:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/Theme.Sherlock" >
<activity
android:name=".Main"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Shadow.xml, dimens.xml are copied from the sample project.

Asked jfeinstein10 and i see that i forgot to add the onOptionsItemSelected method.
Correct code to open (to fix my class above):
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
toggle();
return true;
}
return super.onOptionsItemSelected(item);
}
Should be in the MainActivity class after onCreate.

GoogleAPI added but MapActivity becomes unseen

I have a little problem with googlemap application that I would like to use this tutorial to work with my Eclipse, I have updated all Elipse ADTs, downloaded GoogleAPI but I still have got an error from the IDE that MapActivity from which my HelloWorld Application is to be extended can not be resolved to a type. Am I missing some important imports or settings I need to perform on the Eclipse itself to make it work ?
public class HelloGoogleMapActivity extends MapActivity {
/** Called when the activity is first created. */
#override
protected boolean isRoundDisplayed()
{
return false;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
MapView mapv=(MapView)findViewById(R.id.mapview);
mapv.setBuildInZoomControls(true);
}
}
Also the first "#override" keyword is reported as illegal, which I have no idea why.
[UPDATE]
All the answers offered are correct. And the most correct one is a comment below. Thank you for your code snips. Cool!

for #Override exception jst change once javacompiler from your project properties ...JDK Compliance 1.6 to 1.5 and thn again set it to 1.6...i was facing the same prob.. it is bcz of some jdk build project...or eclipse prob...
And for map Prob
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainlayout"
android:layout_width="fill_parent"

android:orientation="vertical" >
