Hello,

After a lot of test, there is a real issue with your library and gradle 4.4 +

classpath 'com.android.tools.build:gradle:3.0.1'

with in the build.gradle on the root folder

    dependencies {

        classpath 'com.android.tools.build:gradle:3.0.1'

        



        // NOTE: Do not place your application dependencies here; they belong

        // in the individual module build.gradle files

    }

and in the gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

The library is fully working on 4.4 device

but with in the build.gradle on the root folder

    dependencies {

        classpath 'com.android.tools.build:gradle:3.1.0'

        



        // NOTE: Do not place your application dependencies here; they belong

        // in the individual module build.gradle files

    }

and in the gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

i have an exception

So since I've update my gradle to 4.4 I can't use TapLinx Library with my Android 4.4 ?
I've tried your sample on my 4.4 and I got the same error

Do you will try to fix this error for the 4.4 device or you will just end the support for 4.4 version ?

Hello,

this is my gradle file

repositories {

    flatDir {

        dirs 'libs'

    }

    /** Following lines are for accessing the TapLinx jars from Repo directly */

    maven {

        credentials {

            username "sdkuser"

            password "taplinx"

        }

}

private void initLibrary() {

    instance = NxpNfcLib.getInstance();

    instance.registerActivity(this, BuildConfig.TAPLINX_KEY);

}



private void cardLogic(Intent intent) {

    try {

        CardType card = instance.getCardType(intent); // CRASH HERE

        Log.d(TAG, "cardLogic: "+card.getTagName());

        if (card.equals(CardType.DESFireEV1)) {

            ev1 = DESFireFactory.getInstance().getDESFire(instance.getCustomModules());

            ev1.getReader().connect();

            ev1.getReader().setTimeout(TIMEOUT);

            desfireEV1CardLogic();

        }

    } catch (Throwable t) {

        Log.e(TAG, "cardLogic: ", t);

        showError(NfcApplicationIDHelper.getError(this, t.getMessage()));

    }

}

there is the stack
