How to disable "RewardedVideoAd" closing while the ad is not finished?

I started to get interested in Google mobile ads. Right now I am testing RewardedVideoAd functionality with Google given testing ad. Everything works fine, but I can't find the way how to disable ad closing while the ad is not finished.
Below is my abstract code which shows how I am using the RewardedVideoAd method:
public class TestPage extends AppCompatActivity implements RewardedVideoAdListener {
private Button button;
private final static String APP_ADMOB_ID = "[my_app_admob_id]";
private RewardedVideoAd mRewardedVideoAd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_page);
MobileAds.initialize(this, APP_ADMOB_ID);
mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
mRewardedVideoAd.setRewardedVideoAdListener(this);
loadRewardedVideoAd();
button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mRewardedVideoAd.isLoaded()) {
mRewardedVideoAd.show();
}
}
});
}
private void loadRewardedVideoAd() {
mRewardedVideoAd.loadAd("ca-app-pub-3940256099942544/5224354917",
new AdRequest.Builder().build());
}
#Override
public void onRewardedVideoAdLoaded() {
Toast.makeText(this, "Video ad loaded",
Toast.LENGTH_SHORT).show();
}
#Override
public void onRewardedVideoAdOpened() {
Toast.makeText(this, "Video ad opened",
Toast.LENGTH_SHORT).show();
}
#Override
public void onRewardedVideoStarted() {
Toast.makeText(this, "Video ad started",
Toast.LENGTH_SHORT).show();
}
#Override
public void onRewardedVideoAdClosed() {
loadRewardedVideoAd();
}
#Override
public void onRewarded(RewardItem rewardItem) {
Toast.makeText(this, "onRewarded! currency: " + rewardItem.getType() + " amount: " +
rewardItem.getAmount(), Toast.LENGTH_LONG).show();
}
#Override
public void onRewardedVideoAdLeftApplication() {
Toast.makeText(this, "Left app during video ad",
Toast.LENGTH_LONG).show();
}
#Override
public void onRewardedVideoAdFailedToLoad(int i) {
Toast.makeText(this, "Failed to load video ad", Toast.LENGTH_LONG).show();
}
}
Now, when ad video is displayed user can press back button and then appears dialog box with message: Close video?. I want to disable this ability.
But I don't know how it could be done. I tried to #Override onBackPressed() method and inserted if statement with checks boolean value if it is able to do something or not. But it does not work.
So my main question is:
Is there any way to disable ad closing while video is running?
Thank you for any type of help.
P.S.: I have read all "AdMob for Android" instructions and I don't need link of it.

application started crashing when trying to login using facebook after ide error

My application was working perfectly then, after adding the following code LoginManager.getInstance().logOut(); to disconnect from the current facebook account (a developper acount), the ide showed that an error occurred while running the app, but the application launched anyway, but when trying to login, it crashed and now it's not logging in, it keeps crashing! even though I changed nothing except adding that line of code to the next activity to make the app disconnect in case the user want to logout!
here's my java code:

I guess the problem was just in the IDE, something about indexation!! I closed and reopened the IDE and everything is working just fine.

LoaderManager is being called automatically on pressing Back key in Android?

I am newbie in Android. Here is the LoaderManager class I have written code on Button click to initialize Loader. When I am pressing back button of device I came to previous activity and my call to Initialize loader is again called and it automatically starts new activity without pressing any key even my initialize loader is on button click.
Why is it happening so?
LoginActivityService.java
public class LoginActivityService extends Activity implements
LoaderCallbacks<User>
{Context context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login_view_service);
context = this;
userName = (EditText) findViewById(R.id.userName1);
password = (EditText) findViewById(R.id.password1);
loginBtn = (ImageButton) findViewById(R.id.login1);
logoutBtn = (Button) findViewById(R.id.logout1);
loginBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
doLogin(userName.getText().toString(),password.getText().toString());
}
});
}
public void doLogin(String userNameString, String passwordString) {
Log.i("do login button if", "login button clicked" + "username:"
+ userNameString + "passwor:" + passwordString);
if (userNameString.length() == 0 || passwordString.length() == 0) {
Toast.makeText(context, "UserName Or Password Should be Filled",
Toast.LENGTH_SHORT).show();
}
else
{ try {
getLoaderManager().restartLoader(1, null,LoginActivityService.this);
}
catch (Exception e) {
Log.i("do Login Stack Trace if Response false","do Login Stack Trace Catch Block");
e.printStackTrace();
}}
#Override
public Loader<User> onCreateLoader(int id, Bundle args) {
Log.i("in loader", "login button clicked" + "username:"+ userName.getText().toString() + "passwor:"
+ password.getText().toString());
loginLoader = new LoginLoader(context, userName.getText().toString(),
password.getText().toString(), "2013-07-10 01:18:26");
Log.i("login loader", "" + loginLoader);
return loginLoader;
}
#Override
public void onLoadFinished(Loader<User> arg0, User userInstance) {
Log.i("status", "" + userInstance);
if (userInstance == null) {
Toast.makeText(getApplicationContext(),"User Id and Password is wrong", Toast.LENGTH_SHORT).show();
}
else {
Intent intent = new Intent(LoginActivityService.this,
ProposalListActivity.class);
startActivity(intent);
}
}
#Override
public void onLoaderReset(Loader<User> arg0) {
// TODO Auto-generated method stub
// getLoaderManager().restartLoader(10000,null,LoginActivityService.this);
}
}
My problem is I am getting data from Service and "userInstance" is not null so it moves towards nextActivity but when I press back key of device it comes to the previous activity and it automatically moves to the same activity from where we have pressed back key. This is happening because my class that extends AsyncTaskLoader have onloadinBackground() and this method is being called again can someone point me why this is happening:
public class LoginLoader extends AsyncTaskLoader<User>
{
#Override
public User loadInBackground() {
// TODO Auto-generated method stub
User listUser = LoginListService.getLoginInstance().getLoginResult(userName,password,apkVersion);
Log.d(TAG, "load in background");
return listUser;
}
}
Can someone please guide me what code I need to add in this to avoid automatic call of loadinBackground?

Try to destroy the loader once you received data:
public void onLoadFinished(Loader<User> arg0, User userInstance) {
Log.i("status", "" + userInstance);
if (userInstance == null) {
Toast.makeText(getApplicationContext(),"User Id and Password is wrong", Toast.LENGTH_SHORT).show();
} else {
getLoaderManager().destroyLoader(arg0.getId());
Intent intent = new Intent(LoginActivityService.this,
ProposalListActivity.class);
startActivity(intent);
}
}
