Hello,

do you have update your gradle to 4.4 ?
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"

        }

        url "http://maven.taplinx.nxp.com/nexus/content/repositories/taplinx/"

    }

}



dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'taplinx-android:nxpnfcandroidlib:1.4'

    implementation 'com.android.support:support-v4:27.1.0'

    annotationProcessor 'com.github.bumptech.glide:compiler:4.6.1'

    annotationProcessor "android.arch.lifecycle:compiler:1.1.1"

    annotationProcessor "android.arch.persistence.room:compiler:1.0.0"

    testImplementation 'junit:junit:4.12'

    androidTestImplementation 'com.android.support.test:runner:1.0.1'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

}

with

compileSdkVersion 27

compileOptions {

    sourceCompatibility JavaVersion.VERSION_1_8

    targetCompatibility JavaVersion.VERSION_1_8

}

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
