I run Android emulator and crash at "cameraProviderFuture = ProcessCameraProvider.getInstance(requireActivity())" this line. Why?
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val barcodeScannerOptions = BarcodeScannerOptions.Builder()
.setBarcodeFormats(
Barcode.FORMAT_QR_CODE
)
.build()
cameraProviderFuture = ProcessCameraProvider.getInstance(requireActivity())
cameraProviderFuture.addListener(
Runnable {
val cameraProvider = cameraProviderFuture.get()
val preview = Preview.Builder().build()
val cameraSelector = CameraSelector.Builder()
.requireLensFacing(LENS_FACING_BACK)
.build()
preview.setSurfaceProvider(binding.cargoPreviewView.surfaceProvider)
val camera =
cameraProvider.bindToLifecycle(viewLifecycleOwner, cameraSelector, preview)
},ContextCompat.getMainExecutor(requireContext())
)
}
logcat error: java.lang.NoSuchMethodError: No static method getOrCreateInstance(Landroid/content/Context;)Lcom/google/common/util/concurrent/ListenableFuture; in class Landroidx/camera/core/CameraX; or its super classes (declaration of 'androidx.camera.core.CameraX' appears in /data/app/~~pfIVQ_AeL7AM1I9N0OVqPw==/-soiV3Uc-nIKoyBDTJx6EHA==/base.apk) at androidx.camera.lifecycle.ProcessCameraProvider.getInstance(ProcessCameraProvider.java:149) at com.hannlync.mercury.fragment.information_activity.information_fragment.cargo_fragment.CargoFragment.onViewCreated(CargoFragment.kt:47)
After I updated gradle and solve the problem.
// CameraX core library using the camera2 implementation
def camerax_version = "1.0.2"
// The following line is optional, as the core library is included indirectly by camera-camera2
implementation "androidx.camera:camera-core:1.1.0-alpha11"
implementation "androidx.camera:camera-camera2:1.1.0-alpha11"
// If you want to additionally use the CameraX Lifecycle library
implementation "androidx.camera:camera-lifecycle:1.1.0-alpha11"
// If you want to additionally use the CameraX View class
implementation "androidx.camera:camera-view:1.0.0-alpha31"
// If you want to additionally use the CameraX Extensions library
implementation "androidx.camera:camera-extensions:1.0.0-alpha31"
