Since Dynamsoft Barcode Reader is cross-platform, it is easy to get the header file from other editions. Where is the DynamsoftBarcodeReader.h file? The header file does not exist in the SDK package for Android. */ void * pBarcodeReader = nullptr extern "C" JNIEXPORT jobject JNICALL Java_com_example_android_camera2basic_Camera2BasicFragment_readBarcode ( JNIEnv * env, jobject instance, jlong hBarcode, jobject byteBuffer, jint width, jint height, jint stride ) #define LOGE(.) _android_log_print(ANDROID_LOG_ERROR, LOG_TAG, _VA_ARGS_) #define LOGI(.) _android_log_print(ANDROID_LOG_INFO, LOG_TAG, _VA_ARGS_) Extract a platform-compatible shared library from DynamsoftBarcodeReaderAndroid.aar\jni** **libDynamsoftBarcodeReaderAndroid.so. Here I’m going to show you how to invoke native APIs, so open the aar file with a file archiver, such as 7-Zip. To build a barcode reader app in Java, you just need to import the *.aar file as a module. Dynamsoft Barcode Reader for Androidĭownload Dynamsoft Barcode Reader for Android.Įxtract the DynamsoftBarcodeReaderAndroid.aar file from the package. Open Android Studio and select Tools > SDK Manager > SDK Tools. This article shares how to write JNI code for Android barcode detection, as well as how to use Android NDK and CMake to build the C++ code. If we can get the pointer to the native buffer of the camera frame, we can invoke native Barcode Reader APIs directly. In that demo project, the barcode decoding part is implemented in Java, which apparently has room for improvement. binder IPC interface The IPC binder interface facilitates communication over process boundaries. Previously, I shared an article demonstrating how to use Camera2 APIs and Dynamsoft Barcode Reader to build a simple Android barcode reader app. native framework This framework residing in frameworks/av/ provides a native equivalent to the CameraDevice and CameraCaptureSession classes.
