OnBackPress() - Activity is blank using ZBarScannerView

I have implemented Barcode Scanner functionality in my application using ZBarScannerView.
I have an activity which contains multiple fragments and on one fragment I have a scan button. By clicking on that button I jump to scan activity where I have implemented the ZBarScannerView code.
When I got the barcode from scan activity I jumped it back to that fragment which contains the barcode click button. And then if I press back from that fragment it shows blank screen. What should I do?
Please Reply
Code for ScanActivity:
public class ScanActivity extends AppCompatActivity implements ZBarScannerView.ResultHandler {
private ZBarScannerView mScannerView;

I'm assuming After successful barcode scanning you're fetching product data and if data found then you are changing the screen . So change your else statement with this and see if it works
else {
Intent in = new Intent(this, ContainAllFragmentsActivity.class);
in.putExtra("product_art", resultCode);
in.putExtra("source_type", "art");
in.putExtra("jump", "2");
startActivity(in);
finish();

jav.nullPointer .Exception when using Intent's putExtra() method

I keep getting a NulPpointerException, when I use the Intent's putExtras() method like shown below. It is in the onClick method where I create an intent and call the register activity class. I use android"s account authentication mechanism. Whenever the signUpTxt Textview is clicked, the app crushes and the error log trace below shows. What am I missing?
Here is my source code

}
Iam passing the extras from Authenticator.java which extends AbstractAccountAuthenticator, in the addAccount() method
#Override
public Bundle addAccount(AccountAuthenticatorResponse response,
String accountType, String authTokenType,
String[] requiredFeatures, Bundle options)
throws NetworkErrorException {
Bundle result;
if (hasAccount(mContext)) {
result = new Bundle();
Intent i = new Intent(mContext, LoginActivity.class);
i.putExtra(LoginActivity.ARG_ACCOUNT_TYPE, accountType);
i.putExtra(LoginActivity.ARG_AUTH_TYPE, authTokenType);
i.putExtra(LoginActivity.ARG_IS_ADDING_NEW_ACCOUNT, true);
i.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE,response);
result.putParcelable(AccountManager.KEY_INTENT, i);
return result;
}

Based on the API:
Intent.getExtras() returns:
the map of all extras previously added with putExtra(), or null if none have been added
My guess would be that you are not passing in any extras and therefore passing null to the Intent.putExtras() method... Or if you think you are you may be doing so incorrectly.

From
getIntent().getStringExtra(ARG_ACCOUNT_NAME);
I can say thay you have used putStringExtra method, instead of putExtras.
Therefore, when you try getIntent().getExtras it is null.

When I want to make payment in PayPal from android, one dialog comes with payment failure and UNAUTHORIZED_PAYMENT. How can I resolve this issue ? I used PayPal Android SDK.
