Braintree Android SDK Drop-in UI not displayed

I am trying to display the Drop-in UI in my app upon clicking a specific button. I have used the guide from Braintree site but for some reason nothing is happening.
Code below:
OnClick function:
public void onClick(View v){
switch (v.getId()){
case R.id.showUI_button:
onBraintreeSubmit(v);
break;
}
}
Drop-in functions:
public void onBraintreeSubmit(View v) {
PaymentRequest paymentRequest = new PaymentRequest()
.clientToken(token)
.amount("$10.00")
.primaryDescription("Awesome payment")
.secondaryDescription("Using the Client SDK")
.submitButtonText("Pay");
startActivityForResult(paymentRequest.getIntent(this), REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {
if (resultCode == BraintreePaymentActivity.RESULT_OK) {
PaymentMethodNonce paymentMethodNonce = data.getParcelableExtra(
BraintreePaymentActivity.EXTRA_PAYMENT_METHOD_NONCE
);
String nonce = paymentMethodNonce.getNonce();
// Send the nonce to your server.
}
}
}
I have checked that the token is returned from the server.
I have also tried by setting the onClick via the xml code of the button and removing the onClick from the java file but the result is the same, no UI shown.
The log has only two lines
performCreate Call Injection Manager
Timeline: Activity_idle id:android.os.BinderProxy#etc
Any ideas? If more info is needed to understand better let me know

Actually I found this there is a "BraintreeFragment" set up part. Braintree documentation needs to be more clear on this I think.
https://developers.braintreepayments.com/guides/client-sdk/setup/android/v2
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
mBraintreeFragment = BraintreeFragment.newInstance(this, mAuthorization);
// mBraintreeFragment is ready to use!
} catch (InvalidArgumentException e) {
// There was an issue with your authorization string.
}
}
The above code should work along with the previous code posted. mAuthorization is the token and needs to be valid to show the payment screen (so the variable "token" in the previous code posted which in my code I just have as private but visible from the whole activity).
Try with the test token that they have on their page and if this works then the main setup is ok.
https://developers.braintreepayments.com/start/hello-client/android/v2
For setting up tokens on your server, they have further documentation so that those test tokens work on the sandbox.

Published Facebook Feed can Only be Seen by Self

I'm using sromku to share score from my LibGDX game.
The feed was successfully published, but no one can see it but myself (even when my profile is seen by others).
Code:
public class AndroidLauncher extends AndroidApplication implements FacebookConn {
SimpleFacebook mSimpleFacebook;
OnPublishListener onPublishListener = new OnPublishListener() {
#Override
public void onComplete(String postId) {
Log.i("OnComplete", "Published successfully. The new post id = " + postId);
}
};
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Permission[] permissions = new Permission[] {
Permission.USER_PHOTOS,
Permission.EMAIL,
Permission.PUBLISH_ACTION,
};
SimpleFacebookConfiguration configuration =
new SimpleFacebookConfiguration.Builder()
.setAppId("410074072507300")
.setNamespace("sromkuapp")
.setPermissions(permissions)
.build();
SimpleFacebook.setConfiguration(configuration);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
config.useImmersiveMode = true;
initialize(new Jump4Love(this), config);
}
#Override
public void onResume() {
super.onResume();
mSimpleFacebook = SimpleFacebook.getInstance(this);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
mSimpleFacebook.onActivityResult(this, requestCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);
}
#Override
public void submitScore(int score) {
Feed feed = new Feed.Builder()
.setMessage("message")
.setName("name")
.setCaption("caption")
.setDescription("description")
.setPicture("picture")
.setLink("link")
.build();
// Note: the values above aren't the actual values I'm using
// I only simplified them so my code becomes easier to read
mSimpleFacebook.publish(feed, true, onPublishListener);
}
}
I found a similar case in StackOverflow here.
The OP said the following:
Only without using "link" and "picture" it does appear on my friend's
News Feed
I tried removing the link and picture but the result was still the same, so my case is kinda different.
That post still has no acceptable answer btw.
======================================================================
It's useless to promote my game in Facebook if no one can see it.
I have seen posts from friends promoting other games, so I know it is possible.
Anyone has any idea why I'm having this problem?

You need to set your app “live”.
Go to Status & Review tab in app dashboard, on top you find
“Do you want to make this app and all its live features available to the general public?”
… that one you need to set to Yes.
Before setting this to Yes, your app is considered to be in “development mode”, and therefor posts made via it are not shown to users that do not have a role in your app (admin/developer/tester).

There are multiple apps registered for the AuthActivity URI scheme - Dropbox sync issue on Android

Sorry for my poor English and the fact I am a newbie on Android development.
I'm developping an Android app which should send data to the datastore of Dropbox. My problem is, when my code is getting this line:
mAccountManager.startLink(DropboxHelper.this,REQUEST_LINK_TO_DBX);
Then my logcat send me the message below:
10-19 10:40:32.411: W/com.dropbox.client2.android.AuthActivity(28381): There are multiple
apps registered for the AuthActivity URI scheme (db-qeojdcjk0dkkswc). Another app may be
trying to impersonate this app, so authentication will be disabled.
The closer explanation I have found is this one:
Android + DropboxSync startLink
But the comments have not helped me.
Here my code :
public class DropboxHelper extends ActionBarActivity {
// *** Objects and APP_KEY + APP_SECRET are instantiate here ***
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dropbox_activity);
// Set up the account manager
mAccountManager = DbxAccountManager.getInstance(getApplicationContext(), APP_KEY, APP_SECRET);
mUnlinkButton = (Button) findViewById(R.id.unlink_button);
mUnlinkButton.setVisibility(View.GONE);
// Button to link to Dropbox
mLinkButton = (Button) findViewById(R.id.link_button);
mLinkButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if ( mAccountManager.getLinkedAccount() == null )
mAccountManager.startLink(DropboxHelper.this, REQUEST_LINK_TO_DBX);
else
{
Toast.makeText(DropboxHelper.this, "Connection déjà établie, vous pouvez vous déconnecter si vous le souhaitez", Toast.LENGTH_LONG).show();
mUnlinkButton.setVisibility(View.VISIBLE);
}
}
});
mUnlinkButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
mAccountManager.unlink();
Toast.makeText(DropboxHelper.this, "Déconnecté", Toast.LENGTH_LONG).show();
}
});
// Set up the datastore manager
if (mAccountManager.hasLinkedAccount()) {
try {
// Use Dropbox datastores
mDatastoreManager = DbxDatastoreManager.forAccount(mAccountManager.getLinkedAccount());
mLinkButton.setVisibility(View.GONE);
} catch (DbxException.Unauthorized e) {
System.out.println("Account was unlinked remotely");
}
}
if (mDatastoreManager == null) {
// Account isn't linked yet, use local datastores
mDatastoreManager = DbxDatastoreManager.localManager(mAccountManager);
// Show link button
mLinkButton.setVisibility(View.VISIBLE);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_LINK_TO_DBX) {
if (resultCode == Activity.RESULT_OK) {
account = mAccountManager.getLinkedAccount();
try {
// Migrate any local datastores to the linked account
mDatastoreManager.migrateToAccount(account);
// Now use Dropbox datastores
mDatastoreManager = DbxDatastoreManager.forAccount(account);
// Hide link button
mLinkButton.setVisibility(View.GONE);
} catch (DbxException e) {
e.printStackTrace();
}
} else {
// Link failed or was cancelled by the user
}
} else {
super.onActivityResult(requestCode, resultCode, data);
}
}
}
I can't figure out How to solve this issue, I really thank you If you can help me.
Best regards.

This generally means you have more than one app installed using the same app key. Often, this can happen if you have, for example, a sample app from the SDK as well as the app you're developing installed on the same device (or virtual device) using your app key. The solution is just to uninstall one of the apps, or use a different app key in one of them.

PayPal Integration with Android

I have seen some related questions but none focusing on the specific problem I have:
I'm using the PayPal MPL Library.
I build my PayPalPayment object, then create the activity for the checkout to occur. That runs fine. My problem is, on the ResultDelegate I need to call a function from my activity, that occurs after the payment and makes some changes (such as storing SharedPreferences, etc.).
So something like this:
public class ResultDelegate implements PayPalResultDelegate, Serializable {
public void onPaymentSucceeded(String payKey, String paymentStatus) {
System.out.println("SUCCESS, You have successfully completed your transaction.");
System.out.println("PayKey: "+payKey);
System.out.println("PayStatus: "+paymentStatus);
callMyCustomAfterPaymentFunction();
}
...
}
Now the thing is, I tried to create a constructor for ResultDelegate that accepts my activity. My existing code is:
//On the activity class
public class MainMenuActivity extends Activity {
public void onCreate(Bundle savedInstanceState)
{
...
Button buy = (Button) findViewByID(R.id.buy_button);
buy.setOnClickListener(new View.OnClickListener(){
public void onClick(View v)
{
new PurchaseTask(activity).execute();
}
}
}
}
public class PurchaseTask extends AsyncTask <String, Void, String> {
protected String doInBackground()
{
...
PayPal pp = PayPal.getInstance();
CheckoutButton cb = pp.getCheckoutButton(...);
cb.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
ResultDelegate delegate = new ResultDelegate(myActivity);
Intent checkout = PayPal.getInstance().checkout(paument, activity, delegate);
activity.StartActivity(checkoutIntent);
}
}
}
}
//On the ResultDelegate class
public class ResultDelegate implements PayPalResultDelegate, Serializable {
private Activity myActivity;
public void onPaymentSucceeded(String payKey, String paymentStatus) {
System.out.println("SUCCESS, You have successfully completed your transaction.");
System.out.println("PayKey: "+payKey);
System.out.println("PayStatus: "+paymentStatus);
myActivity.performAfterPaymentOperations();
}
...
}
So the goal is to call the activity function from the ResultDelegate. Or even simpler, just to be able to store some SharedPreference changes when the ResultDelegate onPaymentSucceeded() fires.
But I get a NotSerializableException mentioning that the my MyActivity field is not Serializable.
So, then I added the transient identifier to my activity field inside the ResultDelegate, but now I get a NullPointerException.

Paypal Mobile Chekout guide
Implementation provided on paypal website is different from yours. They are doing startActivityForResult() to start PaypalActivity. and when in onActivityResult() method they are checking statusCode to check transaction status and act accordingly.
Follow that document for your implementation.
Here in your code, I donot find a point for using AsyncTask. Your ResultDelegate is Serializable where as Activity is not thats why it is throwing NotSerializableException.
Edit:
As you are developing for Google Android platform, then why not to use Google Checkout In-App?
Edit:
This method will be called when your PaypalActivity will finish. That activity will pass resultCode to this onActivityResult method.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (resultCode) {
case Activity.RESULT_OK:
// The payment succeeded
String payKey = data.getStringExtra(PayPalActivity.EXTRA_PAY_KEY);
// Tell the user their payment succeeded
break;
case Activity.RESULT_CANCELED:
// The payment was canceled
// Tell the user their payment was canceled
break;
case PayPalActivity.RESULT_FAILURE:
// The payment failed -- we get the error from the EXTRA_ERROR_ID
// and EXTRA_ERROR_MESSAGE
String errorID = data.getStringExtra(PayPalActivity.EXTRA_ERROR_ID);
String errorMessage = data
.getStringExtra(PayPalActivity.EXTRA_ERROR_MESSAGE);
// Tell the user their payment was failed.
}
}

You can create you custom listener something like this :
Create a custom listener :
OnDoubleTap mListener;
// Double tap custome listenre to edit photoes
public interface OnDoubleTap {
public void onEvent(Uri imgPath, int mPos);
}
public void setDoubleTapListener(OnDoubleTap eventListener) {
mListener = eventListener;
}
Now call this wherever you want like this :
mListener.onEvent(Uri, 1));
Now whenever you call this listener this will fire in your activity where you use this listener like this :
myCanvas.setDoubleTapListener(new OnDoubleTap() {
#Override
public void onEvent(Uri imgPath, int Pos) {
// TODO Auto-generated method stub
Toast.makeText(mContext, "LISTENER WORKING !!!", Toast.LENGTH_SHORT).show();
}
});
Where myCanvas is object of class where you create you listener.

Try this solution:
PayPalPayment thingToBuy = new PayPalPayment(new BigDecimal(price),getResources().getString(R.string.curruncy_code), getResources().getString(R.string.app_name),
PayPalPayment.PAYMENT_INTENT_SALE);
Intent intent = new Intent(CreateEventStep4.this, PaymentActivity.class);
intent.putExtra(PaymentActivity.EXTRA_PAYMENT, thingToBuy);
startActivityForResult(intent, REQUEST_PAYPAL_PAYMENT);
PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);
if (confirm != null) {
try {
Log.e("paymentExample", confirm.toJSONObject().toString());
JSONObject jsonObj=new JSONObject(confirm.toJSONObject().toString());
String paymentId=jsonObj.getJSONObject("response").getString("id");
System.out.println("payment id:-=="+paymentId);
screenShotFile = takeScreenshot(frmTemplate);
uploadImage(myEvent.getEvent_id(),screenShotFile);
} catch (JSONException e) {
Log.e("paymentExample", "an extremely unlikely failure occurred: ", e);
}

Android: Unable to restart an ListActivity

First post, so please go easy.
I have an app with a handful of tabs, the first is opened on running the app.
One of the tabs is 'My Account' (a ListActivity) showing account options. I switch to this and if the user is not logged in, it, in turn, runs a UserLogon activity using the following:
Intent logonActivity = new Intent(getBaseContext(), UserLogon.class);
startActivityForResult(logonActivity, 0);
To catch the result, I use the following code:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 0){
MainBlock ta = (MainBlock) this.getParent();
TabHost th = ta.getMyTabHost();
th.setCurrentTab(0);
finish();
}
if (requestCode == 100)
{
showAccountOptions();
}
}
In the UserLogon class, I have the usual fare; TextView's and Button's. The intention is that if the user cancels the login, it will revert to the initial tab, or if login is successful, it will show the Account Options. And this is indeed what does happen.
All good so far.
The problem I'm having is that if I cancel the login and return to the first tab, when I select the Accounts tab again, I'm not presented with the UserLogon activity. I was under the impression that finish() would close the UserLogon activity, and the Accounts activity but it would appear not.
So, my question is simply, how do I, in effect, restart the Accounts activity so that the user would be presented with the option to login once more.

We're good people and all willing to help ;-) I'll give it a shot. Still, I'm not quite sure I get that all right.
Basically you have an TabActivity which you setup and where you do something like that:
myTabHost.setOnTabChangedListener(new OnTabChangeListener(){
#Override
public void onTabChanged(String tabId) {
if (tabId.equals("account") && !loggedIn) {
Intent logonActivity = new Intent(getBaseContext(), UserLogon.class);
startActivityForResult(logonActivity, 0);
}
}});
You're basically saying that the first Activity start of UserLogon works, but the second one doesn't, right? Did you debugged to that point to check whether you reach the code which starts the activity again?
Update based on comment
Your UserLogon should always provide a result information, here's a blueprint:
public class UserLogon extends Activity {
public void onCreate(Bundle bundle) {
// ... do something ...
// if activity is canceled this will be the "last" result
setResult(RESULT_CANCELED);
}
public void checkLoginOrSomethingLikeThat() {
Intent result = new Intent();
// put your results in this intent
setResult(RESULT_OK, intent);
// close activity since we have the information we need
finish();
}
}
The parent activity which is waiting for the result should do it like that:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// it's good practice to use a constant for 0 like LOGIN_REQUEST
// otherwise you will ask yourself later "What the hell did 0 stand for?"
if(requestCode == 0){
if (resultCode == RESULT_OK) {
// get needed data from data intent and react on that
} else {
// no success, react on that
}
}
// ... I don't know what your resultCode 100 is but handle itwith the same pattern
}
