Android Capture Image From Camera And Save In Internal Storage
Capturing images from a camera is a common feature in most modern Android applications. However, the process of capturing and saving the image to the internal storage is not always straightforward. In this article, we will explore how to capture an image from the camera and save it on the internal storage of an Android device.
Capture Image From Camera
The first step is to capture an image from the camera. To achieve this, we need to create an instance of the Camera class and set the preview display. We also need to create a surface texture to display the camera preview.
The following code demonstrates how to capture an image from the camera:
```private Camera mCamera;private SurfaceTexture mSurfaceTexture;private void captureImageFromCamera() {try {// Create a new Camera instancemCamera = Camera.open();// Set the preview displaymCamera.setPreviewTexture(mSurfaceTexture);// Start the previewmCamera.startPreview();// Take a picturemCamera.takePicture(null, null, mPictureCallback);} catch (Exception e) {e.printStackTrace();}}private Camera.PictureCallback mPictureCallback = new Camera.PictureCallback() {@Overridepublic void onPictureTaken(byte[] data, Camera camera) {// Save the captured imagesaveImageToInternalStorage(data);}};```Once the picture is taken, we need to save it to the internal storage of the device. To do this, we need to create a new file on the internal storage and write the image data to the file.
Save Image To Internal Storage
The following code demonstrates how to save an image to the internal storage:
The above code creates a new file on the internal storage with the filename "my_image.jpg". The image data is then written to the file using a FileOutputStream. Finally, the MediaScannerConnection is used to scan the saved image and make it available in the device's gallery app.
Conclusion
Capturing images from a camera and saving them to the internal storage is an essential feature in modern Android applications. In this article, we have explored how to capture an image from the camera and save it to the internal storage of an Android device. We hope that this article has been helpful in guiding you through the process of implementing this feature in your application.
