Is there a particular contact at square we can reach out to if we're integrating with the square reader SDK for our internationalised app but based in another country e.g Australia?

Essentially after some SDK details so we can do some testing for our US clients.

When app is not used for few minutes, the square reader shows error "Connecting to reader" message. This started happening from yesterday. Only way to fix this is kill and restart the app.

Stripe Terminal SDK 2.22.0 is using version 4.7.2 of Wire while Square Reader SDK 1.7.4 is using 4.4.0. Here is the response from Stripe team.

stripe/stripe-terminal-android#351 (comment)

I am using square library 1.4.4 targeting android 30 and this is a new crash, previously square payments worked. When I try to take a payment I get the following crash:

Are there any updates on support for Android Q/10/API 29 and above yet? If so, which Reader SDK version? Because, v1.3.6 throws a security exception as of now, which is most likely related to trying to access the identifier (i.e. IMEI) as it says here in the docs. And no, enforcing the READ_PRIVILEGED_PHONE_STATE permission doesn't seem to be a potential workaround here as it mentions, Caution: Third-party apps installed from the Google Play Store cannot declare privileged permissions.

Despite being blunt on my end to assume that this SDK will support the latest Android version in the first place (especially since Android 10 has been around for awhile), are there any workarounds for this in the meantime?

I want to be able to use development and production sdk for debug and release. I was unable to get it to work since the dependency is based on the square application id and even has different credentials for development and production.

Can someone give me an example on how i differentiate them in gradle.

New version of reader SDK (1.7.5) conflicts with zendesk SDK in the permission section.

Manifest merger failed : Attribute uses-permission#android.permission.READ_EXTERNAL_STORAGE@maxSdkVersion value=(31) from [com.squareup.sdk.reader:reader-sdk-665373fc:1.7.5] AndroidManifest.xml:67:9-35
  	is also present at [com.zendesk.belvedere2:belvedere:3.0.5] AndroidManifest.xml:18:9-35 value=(32).
  	Suggestion: add 'tools:replace="android:maxSdkVersion"' to <uses-permission> element at AndroidManifest.xml:65:5-67:38 to override.

I am unable to use androidx with square reader sdk. I see that square is still using old support libraries. Is this change going to happen soon?

Similar to this question without it being addressed (where instead, we have two production Square accounts each pointing to a debug and release environment): #8

^ with that in mind, is it possible to download the Reader SDK dependencies from the repository based on build types when authorizing into it with respective credentials (i.e. our debug/dev creds pointing to a production Square account's Reader SDK, and the release creds pointing to another production Square account's Reader SDK in this case) via the same repository URL? Because, I'm not really seeing any documentation on this as of now.

Here's the relevant parts of the app level build.gradle file:

...

final SQUARE_READER_SDK_APP_ID_DEV = 'sq0idp-T4SClu2rWV2AcYcEiHALXg'
final SQUARE_READER_SDK_APP_ID_PROD = 'sq0idp-cyEZl-H328bxzEh0E4tq5w'
final SQUARE_READER_SDK_VERSION = "1.3.6"

...

buildTypes {
    debug {
        ...

        repositories {
            maven {
                url "https://sdk.squareup.com/android"
                credentials {
                    username SQUARE_READER_SDK_APP_ID_DEV
                    // Set as a property from CI command with one of its env vars
                    password squareReaderSdkPasswordDev
                }
            }
        }

    }
    release {
        ... 

        repositories {
            maven {
                url "https://sdk.squareup.com/android"
                credentials {
                    username SQUARE_READER_SDK_APP_ID_PROD
                    // Set as a property from CI command with one of its env vars
                    password squareReaderSdkPasswordProd
                }
            }
        }
    }
}

...

dependencies { 
    ...

    debugImplementation "com.squareup.sdk.reader:reader-sdk-$SQUARE_READER_SDK_APP_ID_DEV:$SQUARE_READER_SDK_VERSION"
    releaseImplementation "com.squareup.sdk.reader:reader-sdk-$SQUARE_READER_SDK_APP_ID_PROD:$SQUARE_READER_SDK_VERSION"
    runtimeOnly "com.squareup.sdk.reader:reader-sdk-internals:$SQUARE_READER_SDK_VERSION"
    
    ...
}

...

Note that building this locally (via Gradle builds and the ./gradlew androidDependencies task) works properly, but not our CI as mentioned in my SO post: https://stackoverflow.com/questions/61240438/execution-failed-for-task-appandroiddependencies-on-circle-ci-but-not-locall

^ but it passes on CI when only downloading the dependency from one build type (i.e.
temporarily commenting out the release creds to only get the debug one, but doesn't work simultaneously)

I am getting this error, I have no issues with my network:

Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all files for configuration ':app:debugRuntimeClasspath'.

This is a more detailed error:

`1: Task failed with an exception.

• What went wrong:
  Execution failed for task ':app:checkDebugAarMetadata'.

Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
Could not find com.squareup.sdk.reader:reader-sdk-{Application ID I hide it}g:1.7.4.

As opposed to using Square Readers, I was wondering how manual card entries really work under the hood as part of the Reader SDK. To be exact, adding a manual card entry option - the AdditionalPaymentType.MANUAL_CARD_ENTRY enum - into the checkout params (as a Set arg instead) during the checkout process.

Based on the screenshots below, you'll see that a "Card Swiped" message appears at the top with it not really outputting any results (i.e. logs nor it appearing as a transaction within the Square dashboard - whereas other payment types like cash, check, and etc. show up) - is this message really only intended, or do I have to hit a certain API for this to fully process and see actual results?:

library causes following exceptions because of Apps that target Android 9 (API level 28) or higher and use foreground services must request the FOREGROUND_SERVICE permission. This is a normal permission, so the system automatically grants it to the requesting app.

If an app that targets API level 28 or higher attempts to create a foreground service without requesting FOREGROUND_SERVICE, the system throws a SecurityException.

java.lang.RuntimeException: Unable to create service com.squareup.cardreader.dipper.FirmwareUpdateNotificationService: java.lang.SecurityException: Permission Denial: startForeground from pid=21256, uid=10358 requires android.permission.FOREGROUND_SERVICE

Caused by: java.lang.SecurityException: Permission Denial: startForeground from pid=21256, uid=10358 requires android.permission.FOREGROUND_SERVICE

Happy new year!

Hello thanks for all your work in getting the reader sdk setup for Android 10 (#29). Since implementing that we've been seeing a lot of crashes on Samsung and LG devices. I was able to track down it being the square sdk by not using or initializing the sdk and it caused the crashes to stop.

The information I can find related to this issue is related to something new in Android 10.
https://developer.android.com/about/versions/10/behavior-changes-all#xom-binaries

Is the square reader sdk when initializing the sdk trying to do some binary memory inspection? If so I think this will cause issues on Android 10 devices.

Hi guy,
Is there anyway to get the reader's serial number (S/N) or some other unique number by the SDK?

Looking forward!

Not sure where to ask this question, so I'll try here for starters.

After following the steps (particularly steps 1-2) for installing the Reader SDK for Android from the docs, we noticed a strange issue with retrieving the dependencies from Maven. We have two Square accounts (one for the dev environment, and the other for prod) that are both set to "Production Settings" instead of sandbox, neither account is activated, and only one of our Square accounts' (our "prod" one in this case) Reader SDK credentials work for getting the Reader SDK dependency. Why is it that our other account's application ID and repository password can't get us the proper aar for the Reader SDK? Note that we get the same failed results even in this reader-sdk-android-quickstart project after plugging in the creds into the gradle.properties file.

Here's the build failure when trying to sync with Gradle:

Here's the failure when running the task locally (in which we're wondering why a jar file is trying to be retrieved when Maven only has aar and pom files in the SDK's maven repo even though our "prod" one works despite not having a jar file as well?):

Here's the maven repo for the SDK pointing to our "dev" environment, and does this look right to you?:

Hi!
It would be great if there was an example of how to use SDK with different credentials for different product flavors.

The application can be styled and configured for different clients. For iOS I use for this different targets in Xcode and, accordingly, different frameworks. For Android - productFlavors, but I can't figure out, how to set up different SDK credentials for different productFlavors.

productFlavors {
        app1 {}
        app2 {}
    }

maven {
            url "https://sdk.squareup.com/android"
            credentials {
                username SQUARE_READER_SDK_APPLICATION_ID
                password SQUARE_READER_SDK_REPOSITORY_PASSWORD
            }
        }

I realize Q Beta 1 was announced only a few days back but when I run this sample on an Android Q Emulator, the app crashes with the following stack trace:

I am getting this error when launching checkout.

card_transaction_already_in_progress

A checkout operation is already in progress and a card has been presented for payment. Ensure that the in-progress checkout is complete before calling CheckoutManager#startCheckoutActivity again.

What am i doing wrong? How do i check if any payment is in progress? I am making sure to launch checkout only once and still keep getting this error.

1. java.lang.SecurityException: get serial: The user 10318 does not meet the requirements to access device identifiers.

2.com.squareup.EventStreamModule_Prod_ProvideEventStreamServiceFactory.get(EventStreamModule_Prod_ProvideEventStreamServiceFactory.java)

These errors raise while I initialize the square reader in my application.
can you please provide me a better solution to handle this error?

I am using the latest SDK for the square reader.
implementation 'com.squareup.sdk.reader:reader-sdk-Key:1.3.5'
runtimeOnly "com.squareup.sdk.reader:reader-sdk-internals:1.3.5"

Hello.
I'm using the SDK in the app working in Immersive mode. On full screen activity I call:

checkoutManager.startCheckoutActivity(this, params.build());

Checkout activity appears with notification bar and other android controls shown.
Is there a way to start checkout activity fullscreen also?
I use currently latest version of reader sdk, 1.0.4.

I want to use reader sdk and firebase for my project. It seems like the Reader SDK library conflicts with firebase. As soon as I added this to the gradle build:

implementation 'com.google.firebase:firebase-core:16.0.4'

Can you pls let me know how to remove the cash payment selection on the checkout page, I hope to only support credit card, no cash. thank you!

Steps:

• build example app
• authorize SDK
• open Reader settings screen

Expected behavior
Connect button present

Current behavior
Connect button is missing

Android: 13
Device: Pixel 4 simulator, Pixel 5 real device
Reader SDK: 1.7.1

All works fine with 1.6.2

Hi Square Team,

I am trying to connect with device. it's connecting fine with your demo. for my app it's showing Required Reinstallation.

Can you please help me why I am getting this issue? I think any versioning issue.

Thanks,
Amit

With/without a Square Reader device (contactless/chip and magstripe) on-hand, I was wondering how to get signature collections to work during the checkout process. Or, are signatures only intended for transactions done with card swipes via Square Readers?

I've set the boolean flag to true (params.collectSignature(true);) prior to launching a cash transaction (and manual card entries, but to no avail as mentioned in this issue) with the following code:

private void startCheckout(Money checkoutAmount) {
    if (waitingForActivityStart) {
      return;
    }
    waitingForActivityStart = true;

    CheckoutManager checkoutManager = ReaderSdk.checkoutManager();
    CheckoutParameters.Builder params = CheckoutParameters.newBuilder(checkoutAmount);
    // TODO: Signatures still don't seem to be shown even with the following
    params.collectSignature(true);
    Set<AdditionalPaymentType> payments = new HashSet<>();
    payments.add(AdditionalPaymentType.MANUAL_CARD_ENTRY);
    payments.add(AdditionalPaymentType.CASH);
    payments.add(AdditionalPaymentType.OTHER);
    params.additionalPaymentTypes(payments);
    params.note("Testing note...");
    checkoutManager.startCheckoutActivity(this, params.build());
}

... where it just takes me directly straight to the "Transaction Complete" screen instead:

We are using Square ReaderSDK library for implementing communication of Reader with our Point of Sale Android application. We set these two fields for the building of the app to the latest version, because of the need of other libraries, which are requiring it for the correct working:

compileSdkVersion 31
buildToolsVersion 31

Then we also implemented latest Square libs for the above functionality:
implementation "com.squareup.sdk.reader:reader-sdk-$SQUARE_READER_SDK_APPLICATION_ID:1.5.1"
runtimeOnly "com.squareup.sdk.reader:reader-sdk-internals:1.5.1"

Unfortunately, once we tried to build the app even for debug purposes, we received the error message:
Manifest merger failed : android:exported needs to be explicitly specified for . Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See <activity> | Android Developers 1 for details.

We found, that it’s caused by missing the field android:exported for any component in AndroidManifest.xml file which includes parameter with the body. So we went through the merged manifest (once we decreased/reverted the build version and tried to find which components are missing this field and are blocking us from success building). And it looks like, that this files defined within dependent libraries are missing it:

com.squareup.ui.ApiActivity
com.squareup.ui.LocationActivity
com.squareup.ui.main.ApiMainActivity
com.squareup.queue.QueueService$BootReceiver
com.squareup.notification.LocaleChangeReceiver
com.squareup.cardreader.ble.lock.PosMarkerReceiver

Is there a possibility to add that exported field into this SquareReaderSDK library with also all their dependencies so that it will support also the latest Android version 12 (build version code 31)?

My country is not listed in Reader SDK accessible list.
so is there any way, i can change my country in profile.

When the android device goes to sleep, there is a reader sdk crash.

The square chip reader keep disconnecting when there is inactivity for like an hour or so. Documentation says it disconnects after 2 hours of inactivity. Pressing the power button on the chip reader doesn't connect the reader. I have to restart the app to reconnect it.

We are building a solution which requires square reader to always be connected. Is there anything i can do to keep the connection alive? If there is support to keep alive right now, is that something your team will consider adding? Is there any other way i can keep the connection alive?
