Open Cash Drawer

I trigger a cash open command in the Clover Station 2018 and it works, now the same code does not work on the Duo or the Solo, in the Manifest file I have the

<use-permission android:name="clover.permission.POP_CASH_DRAWER_NEW" />


The code is

public void onOpenCashDrawerClick() {

    Context appCt = getApplicationContext();
    CashDrawers cds = new CashDrawers(appCt);
    Log.i("onOpenCashDrawerClick", String.valueOf(cds.list().size()));
    for (int i = 0; i <  cds.list().size(); i++)
    {
        Log.i("inside1for",String.valueOf(i));
        cds.list().iterator().next().pop();
    }

    Set<CashDrawer> drawers = new CashDrawers(appCt).list(); // get the set of connected cash drawers
    for (CashDrawer cd : drawers) {
        Log.i("inside2for", String.valueOf(cd.getDrawerNumber()));
        cd.pop(); // pop each connected cash drawer
    }
}

What version of the clover-android-sdk library are you using? The code you wrote looks correct but I suspect you are using an old version of the clover-android-sdk from before 262.2. Please update to the latest clover-android-sdk which as of writing is 284.


It was briefly noted at https://docs.clover.com/docs/clover-android-sdk-v2622-release-notes that there were improvements to the cash drawer API, specifically the SDK was improved to automatically support new Clover devices so hopefully once you start using this version it cash drawers on all current and future devices will work without needing to update the clover-android-sdk.

In the code the list of cash drawers are always 0, so the line of code that suppose to give me back the list of cash drawers connected to the Clover device does not return any.

Generally we try to make updates seamless but there are times when we make non-backwards compatible changes though we usually warn developers about this in the release notes https://docs.clover.com/docs/release-notes-announcements

Without knowing the errors there is no way to know what errors you are getting there is no way I can suggest how to address them. Can you post a log with the errors you see.

Jacob, I updated the Development studio and the gradle along with the dependencies, my project has included the clover-android-connector-sdk, the clover-android-loyalty-kit and the clover-android-sdk

that is the settings.gradle below

include 'clover-android-sdk'
include 'clover-android-connector-sdk'
include 'clover-android-loyalty-kit'
include 'comprise-smartmoneymanager'

Looks like perhaps you actually downloaded the clover-android-sdk source code and are including it as a module? I wouldn't recommend using it that way.

Prefer obtaining a prebuilt version from maven like so in your build.gradle file in the dependencies area:

implementation 'com.clover.sdk:clover-android-sdk:284'
implementation 'com.clover.sdk:clover-android-loyalty-kit:284'
implementation 'com.clover.sdk:clover-android-connector-sdk:284'

Also it's possible you are hitting this bug Google has recently fixed: https://issuetracker.google.com/issues/223365583 If you are using android gradle plugin 7.1.0, 7.1.1 or 7.1.2 please upgrade to 7.1.3:

classpath "com.android.tools.build:gradle:7.1.3"

Jacob, so I think that the groove library is not loaded, as a result the XmlParser is not available and the xml files like the javadoc.xml is not parsed, I am not sure where in the project to add the dependency..

I don't think XML is related to your issue. To use dependencies please see this example app:

https://github.com/clover/android-examples/tree/master/clover-cfp-examples

In particular see:

https://github.com/clover/android-examples/blob/master/clover-cfp-examples/clover-cfp-examples/build.gradle
