If you pass the extra parameter MediaStore.EXTRA_OUTPUT with the camera intent then camera activity will write the captured image to that path and it will not return the bitmap in the onActivityResult method. If you will check the path which you are passing then … Read more

I had the same issue and find this doc from google: https://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE “Note: if you app targets M and above and declares as using the CAMERA permission which is not granted, then atempting to use this action will result in a SecurityException.” This is really weird. Don’t make sense at all. The app declares Camera … Read more
This is what I’m using import android.content.pm.PackageManager; PackageManager pm = context.getPackageManager(); if (pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) { } All sorts of other fun things to test for are available too – the compass, is location available, is there a front facing camera: http://developer.android.com/reference/android/content/pm/PackageManager.html
private Camera openFrontFacingCameraGingerbread() { int cameraCount = 0; Camera cam = null; Camera.CameraInfo cameraInfo = new Camera.CameraInfo(); cameraCount = Camera.getNumberOfCameras(); for (int camIdx = 0; camIdx < cameraCount; camIdx++) { Camera.getCameraInfo(camIdx, cameraInfo); if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) { try { cam = Camera.open(camIdx); } catch (RuntimeException e) { Log.e(TAG, “Camera failed to open: ” + e.getLocalizedMessage()); … Read more

Even though the old camera API is marked as deprecated, it is still fully functional, and will remain so for quite a while (as nearly all camera-using applications on the Play Store use it currently). You’ll have to ignore Android Studio’s complaints about it being deprecated, but if you want to support Android versions earlier … Read more
I’m using this method -> based on API Demos to get my Preview Size: private Camera.Size getOptimalPreviewSize(List<Camera.Size> sizes, int w, int h) { final double ASPECT_TOLERANCE = 0.1; double targetRatio=(double)h / w; if (sizes == null) return null; Camera.Size optimalSize = null; double minDiff = Double.MAX_VALUE; int targetHeight = h; for (Camera.Size size : sizes) … Read more
