Answer 1

You most likely imported the wrong camera class at the top of your source file, which is android.graphics.Camera.
You need android.hardware.Camera instead.
Thanks

Answer 2

I think you have not added the camera permission. See below - you need to add this in your manifest;
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

Answer 3

Check your imports. I had a similar problem and the Camera object Eclipse chose for me was: import android.graphics.Camera; instead it should be: import android.hardware.Camera;

Answer 4

If none of the above work:
check to see if you are requesting camera permission manually. Newer Android permissions (API > 23) are set at runtime, not install time.
See: https://developer.android.com/training/permissions/requesting.html

Answer 5

Please create a variable like this:
android.hardware.Camera camera ;
and then try open method :
camera = camera.open();
// this is working on my android studio

Answer 6

I have Faced the same problem till i reached that older versions of android will work properly until Android Marshmallow so it needs a runtime permission in order to proceed and show the camera ...
you can read about it in this link https://developer.android.com/training/permissions/requesting.html
for me i used a 3rd party library to do all this stuff for me from this link and all resolved ..

I have faced a lot of issues while using integrating camera native/camera2 api. The code was bulky. To avoid complexity and compatibility issues google provide new CameraX api in new android jetpack library. See the google provided documentation https://developer.android.com/training/camerax. There is also a Kotlin based library i found on github https://github.com/robertlevonyan/CameraXDemo. You can get more clearity with less code.

Waged right!!!
A permission request is required. And I found the right code. he works.
I advise you to look at this article to initially connect the camera:
https://habr.com/ru/post/112272/
enter image description here
if(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this, new String[] {Manifest.permission.CAMERA}, 15); }
