Mapbox SDK in Android Fragment

I want to show mapbox mapview in fragment but i cant do that. I looked lots of problems and solutions however i cant solve my issue. App is crashing always. BottomNavigation class is main class, MapFragment is fragment class which i want to see map. Also i attached Xml codes. Thank you!

Problem is that there is no setted access token. Access token should be set before inflating. That's all.

Android Fragment not showing in app

So I'm creating an app and I'm stuck with this problem of my fragment not showing on screen. It looks just fine on Android Studio preview, but when run on real device I only see action bar and nothing else.
Here's my fragment code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<EditText
android:id="#+id/fragment_login_userEmail"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Email"/>
<EditText
android:id="#+id/fragment_login_userPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Password"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/fragment_login_loginButton"
android:text="Sign In"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/fragment_login_registerButton"
android:text="Sign Up"/>
</LinearLayout>

Fragment fragment = fragmentManager.findFragmentById(R.id.activity_fragment_base_fragmentContainer);
if (fragment ==null) {
fragment = createFragment();
fragmentManager.beginTransaction()
.add(R.id.activity_fragment_base_fragmentContainer, fragment)
.commit();
}
}
}
What am I doing wrong?

if (fragment ==null) {
fragment = createFragment();
fragmentManager.beginTransaction()
.add(R.id.activity_fragment_base_fragmentContainer, fragment)
.commit();
}
Problems is .add

VideoView preventing other fragments in a ViewPager from showing up?

I have a simple Android program which uses ViewPager to swipe between two tabs. Each tab has its own fragment. One fragment plays video while the other simply shows some text. The problem is when the video plays and I swipe to the information tab there is no text and it is completely black. I know it must be because of the video layout. Reason being is I have tested it with two information tabs instead and the information shows up perfectly on each tab. Here's my code.
MainActivity.java

How to add dynamically several fragments

I create a little app with 3 static fragments and a view pager adapter. But what I want is to create Only one kind of fragment and with a button "add" , add other fragment which will be adapted by the view pager.. here is what i have done
FragmentTab1.java ; FragmentTab2 ; FragmentTab3 have the same code
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentTab2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Get the view from fragmenttab2.xml
View view = inflater.inflate(R.layout.fragmenttab2, container, false);
return view;
}
}
here is my MainActivity.java
import android.app.Fragment;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
//Button adfg = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
// Locate the viewpager in activity_main.xml
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
// Set the ViewPagerAdapter into ViewPager
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
}
}

You need to create a method to add the fragment on the subclass of FragmentPagerAdapter, more or less like this :
//use those lists
private List<Fragment> listFragment = new ArrayList<Fragment>();
private List<String> listFragmentTitle = new ArrayList<String>();
private List<Integer> listFragmentIcon = new ArrayList<Integer>();
public void addTab(Fragment fragment,String title, int icon) {
listFragment.add(fragment);
listFragmentTitle.add(title);
listFragmentIcon.add(icon);
}
#Override
public Fragment getItem(int position) {
// TODO Auto-generated method stub
return listFragment.get(position);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return listFragment.size();
}
Then you just need to use it on the subclass of Activity, example :
//create a private method to set a new - dynamic fragment in the ACTIVITY
private Fragment setFragment(int pos)
{
MyFragment myFragment = new MyFragment();
Bundle data = new Bundle();
data.putString("test", "test");
myFragment.setArguments(data);
return myFragment;
}
Finally, add the fragment (for example, inside an onClickListener) :
//INSIDE an onClickListener
pagerAdapter.addTab(setFragment(position), getItem(position).getName(), R.drawable.ic_launcher);

this is my MainActivity.java class #BlazeTama
package com.light.frag;
import com.light.frag.R;
import com.light.frag.ViewPagerAdapter;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;

public class MainActivity extends FragmentActivity implements OnClickListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Locate the viewpager in activity_main.xml
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
// Set the ViewPagerAdapter into ViewPager
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
Button ajou = (Button) findViewById(R.id.bajou);
ajou.setOnClickListener(this);
}
private Fragment setFragment(int pos)
{
MyFragment myFragment = new MyFragment();
Bundle data = new Bundle();
data.putString("test", "test");
myFragment.setArguments(data);
return myFragment;
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bajou:
ViewPagerAdapter.addTab(setFragment(position), getItem(position).getName(), R.drawable.ic_launcher);
break;
}
}
}

Error while using ListFragement

I am developing an android app for online payment for which I want to display Lists of restaurants under the tab named Restaurants. Same as this some other tabs will have list below them and a few tabs will have form under them (if possible and not difficult otherwise I will stay with the lists only)
Here is the code I have written. It contains an error in the Adapter class and may be some logical errors which I am not sure about as this is my first ever android app.
