It will change to production mode when you set the live app id instead of the sandbox id.

This procedure could be used to handle a e-commerce payments ?

Erel · Mar 12, 2014

Not sure that I understand. You can use this library to accept payments with PayPal from within your app.

@Erel what I have to write insted of [email protected] ?

Erel · Mar 16, 2014

This is the customer email address it can also be the customer phone number.

luke2012 · Mar 17, 2014

Ok. But in this case the email is hardcoded for test purpose.
In a production environment I don't know the customer email address programmatically and I suppose that the customer email will be input from the paypal login screen.
Correct?

Erel · Mar 18, 2014

The field will not be filled automatically. PayPal documentation only says that it should be the customer email address or phone number. I agree that it is not completely clear.

You can see it here: https://developer.paypal.com/webapps/developer/docs/classic/mobile/ht_mpl-itemPayment-Android/

Got it...but no PopUp appears for logging in.
I added also the part in the manifest editor:

B4X:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="17"/>
<activity android:name="com.paypal.android.MEP.PayPalActivity"
  android:theme="@android:style/Theme.Translucent.NoTitleBar"
  android:configChanges="keyboardHidden|orientation"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
'End of default text.

Nor with the Sandbox neither with the live-id.
The button appears after a second or so, but pressing it gives no result.

Your manifest editor should look like this:

B4X:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: http://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="14"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
AddApplicationText(
<activity android:name="com.paypal.android.MEP.PayPalActivity"
  android:theme="@android:style/Theme.Translucent.NoTitleBar"
  android:configChanges="keyboardHidden|orientation"/>)
'End of default text.

It works ...

Hello Erel,

you did again a great job with that library. Thanks a lot!

But I have just one question: The dialogs in the sandbox-mode all comming in English language.
If I will change from sandbox-mode to production-mode, do they come f.e. in German?

You told:

In v1.0 you cannot change the language. However such a feature can be added in a simple update

Is there an update?

Erel · Mar 19, 2014

You can explicitly set it with this code (put it inside the ready event):

B4X:

Dim jo As JavaObject
jo.InitializeStatic("com.paypal.android.MEP.PayPal").RunMethodJO("getInstance", null).RunMethod("setLanguage", Array As Object("de_DE"))

Thank you very much, Erel!

Hello Erel and luke2012,

@Erel what I have to write insted of [email protected] ?

Erel answered:

This is the customer email address it can also be the customer phone number.

... but sorry ... there is a misunderstanding: This is NOT the customer-email-adress, it is the email-adress of "your company" in the test area of paypal sandbox.

To this email-adress where sent the notifications, when you test the app in sandbox-mode.
You can see them on this paypal-page https://developer.paypal.com/webapps/developer/dashboard/email
(first you have to login to your paypal-account).

So my problem is now, that the sandbox-mode is working, but how to code it to the "real-mode"?

PayPalX.Initialize("APP-80W284485P519543T", True, "PayPal") '-- Testkonto --

... this -- Testkonto -- above works ... but this -- LIVE-KONTO -- ...

'PayPalX.Initialize("AReJj............", False, "PayPal") '-- LIVE-KONTO !!! --

... is not working! I changed the static "APP-80W284485P519543T" into the real App-ID (which I've got from PayPal) and the "True" for using sandbox-mode into "False" for using real-mode. Experiment is not working.

In the next step I changed the line with the "request" from sandbox-mode ...

PayPalX.RequestPayment("EUR", 2, "[email protected]", "JOTHA", PayPalX.PAYMENT_TYPE_SERVICE) '-- Testkonto --

into real mode:

PayPalX.RequestPayment("EUR", 2, "[email protected]", "JOTHA", PayPalX.PAYMENT_TYPE_SERVICE) '-- LIVE-KONTO !!! --

Experiment is not working.

On the PayPal-website "https://developer.paypal.com/docs/classic/lifecycle/goingLive/" is a description, how to go live. There are 6 steps:

To take your application live:

Ensure your application adheres to the PayPal Application Policies and Guidelines.

Update the Sandbox API credentials in your PayPal calls to those assigned to a live PayPal account.

Update your PayPal endpoints from the Sandbox to the PayPal production servers.

Register your application with PayPal.

If your application makes use of Adaptive operations, obtain a live AppID.

Go Live !

Are these steps in the library included?
Why does my LIVE-code don't work?

Erel · Mar 20, 2014

Which error do you get?

JOTHA · Mar 20, 2014

I dont get an error message.

In the case of "sandbox-mode" the sandbox is shown with the PayPal-login.
In the case of "real-mode" nothing is shown and there is no error message.

Erel · Mar 20, 2014

This is the line that initializes the PayPal object:

B4X:

pp = PayPal.initWithAppID(ba.context, AppId, Sandbox ? PayPal.ENV_SANDBOX : PayPal.ENV_LIVE);

If Sandbox is False then it will use PayPal.ENV_LIVE.

If you like I can post the library code. I don't think that the problem is there.

JOTHA · Mar 20, 2014

so ...

pp.Initialize("AReJj............", False, "PayPal")

... should work?

Erel · Mar 20, 2014

JOTHA · Mar 20, 2014

OK Erel, thank you!
Is there anyone who has tested in "real-mode"?

In the case of "sandbox-mode" everything works and there is a dialog with the sandbox on the PayPal-Website. I receive E-Mail notifications via the test-accounts.

I trust in you Erel ... so I have to check if there is any mistake with the App-ID or anything else ... so it would be helpful to know if there is anywhere a real working app.

I will report, if I have a solution.

Erel · Mar 20, 2014

I tested it in their sandbox mode. The library code is quite simple and only wraps PayPal SDK.

JOTHA · Mar 24, 2014

I tried again, but no solution.

There are 2 IDs at PayPal in the "Live credentials":
a) Client ID
b) Secret

Does anybody know what is equal to the "AppID"?
I mean what to replace instead the "AppID" = a) or b) ???

Erel · Mar 25, 2014

Have you tried to contact them or post in their forum?
