I am facing error while generating APK after adding this library in my project

Error:Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Lcom/dlazaro66/qrcodereaderview/QRCodeReaderView$OnQRCodeReadListener; Error:com.android.dex.DexException: Multiple dex files define Lcom/dlazaro66/qrcodereaderview/QRCodeReaderView$OnQRCodeReadListener; Error: at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:563) Error: at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:608) Error: at com.android.dx.merge.DexMerger.mergeClassDefs(DexMerger.java:545) Error: at com.android.dx.merge.DexMerger.merge(DexMerger.java:194) Error: at com.android.dx.merge.DexMerger.mergeDexes(DexMerger.java:167) Error: at com.android.builder.dexing.DexArchiveMergerCallable.mergeDexes(DexArchiveMergerCallable.java:66) Error: at com.android.builder.dexing.DexArchiveMergerCallable.call(DexArchiveMergerCallable.java:54) Error: at com.android.builder.dexing.DexArchiveMergerCallable.call(DexArchiveMergerCallable.java:37) Error: at java.util.concurrent.ForkJoinTask$AdaptedCallable.exec(ForkJoinTask.java:1424) Error: at java.util.concurrent.ForkJoinTask.doExec(ForkJoinTask.java:289) Error: at java.util.concurrent.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1056) Error: at java.util.concurrent.ForkJoinPool.runWorker(ForkJoinPool.java:1692) Error: at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157) Error:java.lang.RuntimeException: com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lcom/dlazaro66/qrcodereaderview/QRCodeReaderView$OnQRCodeReadListener; Error:com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lcom/dlazaro66/qrcodereaderview/QRCodeReaderView$OnQRCodeReadListener; Error:com.android.dex.DexException: Multiple dex files define Lcom/dlazaro66/qrcodereaderview/QRCodeReaderView$OnQRCodeReadListener;
