I want to delete the message from history in Pubnub and I am using this code
AppController.pubNub.deleteMessages()
.channels(Arrays.asList(Constants.channelAtLogin+chat_user_id))
.start(result.getMessages().get(i).getTimetoken())
.end(result.getMessages().get(i).getTimetoken())
.async(new PNCallback<PNDeleteMessagesResult>() {
#Override
public void onResponse(PNDeleteMessagesResult result, PNStatus status) {
Log.d("delete_message",result.toString());
}
});
But message is not deleted . Please help.
It seems like you are trying to show the result variable from your call which shouldn't give any result. The proper way to check if you're getting an error is to log the status. In other words, the code you're using above in essence is the correct code and is the one supported by PubNub.
pubnub.deleteMessages()
.channels(Arrays.asList("channel_1", "channel_2"))
.start(1460693607379L)
.end(1460893617271L)
.async(new PNCallback<PNDeleteMessagesResult>() {
#Override
public void onResponse(PNDeleteMessagesResult result, PNStatus status) {
// The deleteMessages() method does not return actionable data, be sure to check the status
// object on the outcome of the operation by checking the status.isError().
Log.d("Message_Deleted", status.isError().toString());
}
});
If it isn't working the next step is to verify the data from the variables you are passing in.

I want to send a String message to database when user presses a specific button in the LibGDX game I am designing for android. How do I go about doing that? Following is the code I tried. But it does not work.
Net.HttpRequest httpRequest = new Net.HttpRequest();
httpRequest.setMethod("POST");
httpRequest.setUrl("URL is here");
httpRequest.setContent("INSERT INTO `game_table` (`Button`) VALUES ('Button 1 Pressed')");
Net.HttpResponseListener httpResponseListener = new Net.HttpResponseListener() {
#Override
public void handleHttpResponse(Net.HttpResponse httpResponse) {
Gdx.app.log("Log httpResponse", httpResponse.getResultAsString());
}
#Override
public void failed(Throwable t) {
}
#Override
public void cancelled() {
}
};
Gdx.net.sendHttpRequest(httpRequest,httpResponseListener);
Log does not provide anything in android monitor. I also tried using AsyncTask and without AsyncTask to implement this code. But neither works.
Am I missing something? If so could you give me small code snippet that will work?
You don't need to use an AsyncTask, libGDX' HTTPRequest is async out of the box.
You did not log anything if the request fails or is cancelled so probably that's the case.
I am trying to perform some task based on the data retrieved from Firebase.
for (inti=0;i<dateList.size();i++)
{
attendanceDateRef= attendanceRef.child(dateList.get(i));
attendanceClassRef= attendanceDateRef.child(ViewAttendanceSelectClassActivity.selectedClass);
attendanceClassRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshotdataSnapshot) {
for (DataSnapshotdsp : dataSnapshot.getChildren())
{
attendanceList.add(dsp.getValue(String.class));
Log.e("attendanceListValues",dsp.getValue(String.class));
}
}
#Override
public void onCancelled(DatabaseErrordatabaseError) {
}
});
}
intindex=1;
for (inti=1;i<=attendanceList.size();i++)
{
if(i%4==0)
{
fullDateRangeList.add(dateList.get(index));
index++;
}
else
{
fullDateRangeList.add(dateList.get(index));
}
}
Log.e("fullDateRangeList",String.valueOf(fullDateRangeList.size()));
Log.e("attendanceList",String.valueOf(attendanceList.size()));
above code is written on the OnClick event of a Button , when I click on the Button following output is generated on logcat:
fullDateRangeList:0
attendanceList:0
attendanceListValues:Value1
attendanceListValues:Value2
attendanceListValues:Value3
attendanceListValues:Value4
.
.
.
attendanceListValues:ValueN
from the above output it looks like second loop is executing before data is retrieved from Firebase and that is why size of fullDateRange and attendanceList is 0.
is there any way i can prevent second loop from executing until data is stored in attendanceList?
You cannot stop that method or make it wait until you get the all the data from your database. This is the behaviour of an asynchronous method. You need to change the logic of your code a little bit by declaring and using that data only inside the onDataChange() method, otherwise it will be always empty.
Also there is another approach. If you want, you can dive into the asynchronous world and use my answer from this post.
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.
I am trying to pass results from scanning into asynctask, because then I need to call php script from server. But somehow it does not work.
Asynctask should be functional, but now after some time I am not sure about anything.
But when I use this code:
#Override
public void handleResult(com.google.zxing.Result result) {
Log.v("TAG", result.getText());
mScannerView.resumeCameraPreview(this);
}
It works and logs my result.
And when I change it into this:
#Override
public void handleResult(com.google.zxing.Result result) {
Log.v("MATEJ", result.getText());
ScannerService scannerService = new ScannerService(this);
scannerService.execute(result.getText());
mScannerView.resumeCameraPreview(this);
}
It logs nothing and application stops working without error message.
Please assist in this. I can't seem to create a suitable test for this method:
protected void startInterfacing() {
mLiveAuthClient.login(mView.context(), Arrays.asList(SCOPES), new LiveAuthListener() {
#Override
public void onAuthComplete(final LiveStatus liveStatus, final LiveConnectSession liveConnectSession,
Object o) {
// Login successful and user consented, now retrieve user ID and connect with backend server
getUserIdAndConnectWithBackendServer(liveConnectSession, mLiveAuthClient);
}
#Override
public void onAuthError(LiveAuthException e, Object o) {
// We failed to authenticate with auth service... show error
if (e.getError().equals("access_denied") ||
e.getMessage().equals("The user cancelled the login operation.")) {
// When user cancels in either the login or consent page, we need to log the user out to enable
// the login screen again when trying to connect later on
logUserOut(mLiveAuthClient, false);
} else {
onErrorOccured();
}
}
});
}
I'll explain abit what goes on here:
I'm trying to authenticate my client and log into OneDrive.
The method starts with a call to the Live SDK's login method. That SDK object is given to me from outside this class. So I can basically mock it.
Here's what I'm struggling with:
I do not need to test the call to the login method because it is not mine. I do need to test the call to getUserIdAndConnectWithBackendServer() inside onAuthComplete. But this method requires a liveConnectSession object. How do I provide that? It is given to me on the onAuthComplete method.
How do I mock the calls to onAuthComplete and onAuthError? I read about ArgumentCaptor but when I use that, I need to provide the arguments to those methods when I call the actual method.
For instance, argument.getValue().onAuthComplete() requires me to add arguments to this call. What do I actually provide here?
Here is the next method which is roughly the same but has its own issues:
protected void getUserIdAndConnectWithBackendServer(final LiveConnectSession liveConnectSession, final LiveAuthClient
authClient) {
final LiveConnectClient connectClient = new LiveConnectClient(liveConnectSession);
connectClient.getAsync("me", new LiveOperationListener() {
#Override
public void onComplete(LiveOperation liveOperation) {
// We got a result. Check for errors...
JSONObject result = liveOperation.getResult();
if (result.has(ERROR)) {
JSONObject error = result.optJSONObject(ERROR);
String code = error.optString(CODE);
String message = error.optString(MESSAGE);
onErrorOccured();
} else {
connectWithBackend(result, liveConnectSession, authClient);
}
}
#Override
public void onError(LiveOperationException e, LiveOperation liveOperation) {
// We failed to retrieve user information.... show error
onErrorOccured();
logUserOut(authClient, false);
}
});
}
In here I would like to mock the JSONObject for instance. But how do I call the onComplete method, or the onError method. And what would I provide as the arguments the methods provide me with. LiveOperation for instance?
Thank you!!
The solution I eventually used was to use mockito's doAnswer() structure.
This enabled me to get the callback argument and call one of its methods.
Another solution was to use an ArgumentCator.
