Jetpack Camerax Example Applicaiton | CameraX | Databinding | Video Capture.
To get started with the cameraX in android studio with java. CameraX is a jetpack library it helps the camera application to built very easy with all the necessary functions developers needed. for more refer here
First you need to implement the cameraX dependencies in your app.build.gradle file update the camerax_version with the current version.
// CameraX core library using camera2 implementation
def camerax_version = "1.0.0"
implementation "androidx.camera:camera-core:${camerax_version}"
implementation "androidx.camera:camera-camera2:${camerax_version}"
implementation "androidx.camera:camera-lifecycle:${camerax_version}"
// CameraX View class
implementation 'androidx.camera:camera-view:1.0.0-alpha28'
Ask for the permission in the AndroidManifest file
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
tools:ignore="ScopedStorage"/>
<uses-feature android:name="android.hardware.camera.any"
android:required="true"/>
<uses-permission android:name="android.permission.RECORD_AUDIO"/><uses-feature android:name="android.hardware.camera.flash" />
if you need audio or flash function just add those permission in the manifest file.Let's starts building the Image capture Camera . In this example i use the data-binding method . you can use normal method too.
For enabling data-binding add the below line in your app.build.gradle file inside android tag.
buildFeatures {
dataBinding = true
}
In Xml first add the PriviewView to view the camera image in the screen in this example i added the priview and some images to capture and after capture to show the image . everithing is in there in this xml file . camera_activity.xml
<androidx.camera.view.PreviewView
android:id="@+id/viewFinder"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Add this PreviewView component in your camera_activity.xml file. Then add one button for capture the image from the camera
Initialise the executor and the provider in your oncreate method. First get the required permission in the starting otherwise you can't see any image or preview in the application.
ExecutorService camaraExecutor = Executors.newSingleThreadExecutor();
ListenableFuture<ProcessCameraProvider> cameraProviderFuture = ProcessCameraProvider.getInstance(activity);
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if(requestCode == REQUEST_CODE_PERMISSIONS){
if (allPermissionsGranted(permissions,activity)) {
startCamera();
} else{
activity.requestPermissions(permissions,1);
Toast.makeText(activity, "Permissions not granted by the user.", Toast.LENGTH_SHORT).show();
}
}}
Inside the permission granted. going to start the camera . lets Initialise the cameraProvider in there
private void startCamera() {
cameraProviderFuture.addListener(new Runnable() {
@Override
public void run() {
try {
cameraProvider = cameraProviderFuture.get();
initPreview(cameraProvider,CameraSelector.LENS_FACING_BACK);
} catch (ExecutionException | InterruptedException e) {
// No errors need to be handled for this Future.
// This should never be reached.
e.printStackTrace();
}
}
}, ContextCompat.getMainExecutor(activity));
}
cameraselector we can provide the basic camera properties you want to change like fron cam or back came which cam you need to access like the
// camera selector use case
cameraSelector = new CameraSelector.Builder()
.requireLensFacing(CameraSelector.LENS_FACING_BACK)
.build();
ImageAnalysis you can you that for analysis the image like automation . using opencv to dedect somthing like that
ImageAnalysis imageAnalysis = new ImageAnalysis.Builder()
.setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
.build();
ImageCapture is class where you can provise the frame radius image quality , camera rotation, like that all the image properties
// imagecapture user case
ImageCapture.Builder builder = new ImageCapture.Builder();
imageCapture = builder
.setCaptureMode(ImageCapture.CAPTURE_MODE_MAXIMIZE_QUALITY)
.setTargetRotation(activity.getWindowManager().getDefaultDisplay().getRotation())
.setTargetAspectRatio(AspectRatio.RATIO_4_3)
.build();
// video capture use case
videoCapture = new VideoCapture.Builder()
.setTargetRotation(activity.getWindowManager().getDefaultDisplay().getRotation())
.setCameraSelector(cameraSelector)
// .setVideoFrameRate(30)
.setTargetAspectRatio(AspectRatio.RATIO_4_3)
.build();
In the initPreview going to bind all the camera properties and the preview components going to initialise.
@SuppressLint("RestrictedApi")
void initPreview(@NonNull ProcessCameraProvider cameraProvider, int lensFacingBack) {
cameraProvider.unbindAll();
try {
// preview user case
Preview preview = new Preview.Builder()
.build();
preview.setSurfaceProvider(cameraActivityBinding.viewFinder.getSurfaceProvider());
// camera selector use case
cameraSelector = new CameraSelector.Builder()
.requireLensFacing(lensFacingBack)
.build();
ImageAnalysis imageAnalysis = new ImageAnalysis.Builder()
.setBackpressureStrategy(ImageAnalysis.STRATEGY_KEEP_ONLY_LATEST)
.build();
// imagecapture user case
ImageCapture.Builder builder = new ImageCapture.Builder();
imageCapture = builder
.setCaptureMode(ImageCapture.CAPTURE_MODE_MAXIMIZE_QUALITY)
.setTargetRotation(activity.getWindowManager().getDefaultDisplay().getRotation())
.setTargetAspectRatio(AspectRatio.RATIO_4_3)
.build();
// video capture use case
videoCapture = new VideoCapture.Builder()
.setTargetRotation(activity.getWindowManager().getDefaultDisplay().getRotation())
.setCameraSelector(cameraSelector)
// .setVideoFrameRate(30)
.setTargetAspectRatio(AspectRatio.RATIO_4_3)
.build();
preview.setSurfaceProvider(cameraActivityBinding.viewFinder.getSurfaceProvider());
camera = cameraProvider.bindToLifecycle((LifecycleOwner) this, cameraSelector, preview, imageCapture,videoCapture);
}catch (Exception e){
e.printStackTrace();
Log.d(TAG, "bindPreview: Exception" + e.getMessage());
}
}
Don't forget to close the image.close in side there.
you can save directly the captured image in your cache or internal storage for them mostly you need the ManagedInternal storeage Permission you needed .
File myPath = getInternalStorageDir(internalStorageDir, videoFormat, Environment.DIRECTORY_MOVIES);
VideoCapture.OutputFileOptions outputFileOptions = new VideoCapture.OutputFileOptions.Builder(myPath).build();
Log.d(TAG, "takeVideo: long press");
startCount();
videoCapture.startRecording(outputFileOptions, camaraExecutor, new VideoCapture.OnVideoSavedCallback() {
@Override
public void onVideoSaved(@NonNull VideoCapture.OutputFileResults outputFileResults) {
Log.d(TAG, "onVideoSaved: success");
activity.runOnUiThread(() -> {
try {
cameraActivityBinding.submitImg.setVisibility(View.VISIBLE);
cameraActivityBinding.previewImage.setVisibility(View.GONE);
cameraActivityBinding.cameraLayout.setVisibility(View.GONE);
cameraActivityBinding.previewLayout.setVisibility(View.VISIBLE);
cameraActivityBinding.previewVideo.setVisibility(View.VISIBLE);
MediaController mediaController = new MediaController(activity);
mediaController.setAnchorView(cameraActivityBinding.previewVideo);
// Setting MediaController and URI, then starting the videoView
cameraActivityBinding.previewVideo.setMediaController(mediaController);
cameraActivityBinding.previewVideo.setVideoURI(outputFileResults.getSavedUri());
cameraActivityBinding.previewVideo.requestFocus();
cameraActivityBinding.previewVideo.setZOrderOnTop(true);
cameraActivityBinding.previewVideo.start();
cameraActivityBinding.previewVideo.setVideoURI(outputFileResults.getSavedUri());
imagePath = outputFileResults.getSavedUri().getPath();
Log.d(TAG, "onVideoSaved: " + outputFileResults.getSavedUri());
} catch (Exception e) {
Log.d(TAG, "onVideoSaved error: " + e.getMessage());
}
});
}
@Override
public void onError(int videoCaptureError, @NonNull String message, @Nullable Throwable cause) {
Log.d(TAG, "onError: " + message);
stopRecording();
}
});
VideoCapture.OutputFileOptions have the file path to store the video location
the final XML code , <layout> tag is used for data binding . if your using the data binding you kept like that otherwise just remove that . the listener i'm using to communicate with the activity. for images use the appropriate needed images i leave that with blank white. camera_activity.xml
