Android open camera from button

Question

I hope this isn t a duplicate question but I am making an app that I want a button to open the camera app  the default android camera separately   How do I got about doing that  I know there is a function   intent setAction MediaStore ACTION IMAGE CAPTURE    Do I need to use that  And how do I call the button from the xml file   Also do I need to worry about storing that picture or video or will the default camera app take care of that

the below code does exactly what you want

//use this intent on click event

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(cameraIntent,CAMERA_REQUEST);

// the above code is used in 'on activity Result'

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);

    if (requestCode == CAMERA_REQUEST) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");
        image.setImageBitmap(photo);
    }
}

To call the camera you can use   Intent intent   new Intent  android media action IMAGE CAPTURE    startActivity intent     The image will be automatically saved in a default directory   And you need to set the permission for the camera in your AndroidManifest xml    lt uses-permission android name  android permission CAMERA  gt   lt  uses-permission gt

You are correct about the action used in Intent but it s not the only thing you have to do  You ll also have to add   startActivityForResult intent  YOUR REQUEST CODE     To get it all done and retrieve the actual picture you could check the following thread   Android - Capture photo

For me this worked perfectly fine     Intent intent new Intent MediaStore ACTION IMAGE CAPTURE    startActivity intent     and add this permission to mainfest file    lt uses-permission android name  android permission CAMERA  gt    It opens the camera after capturing the image it saves the image to gallery with a new image set

I know it is a bit late of a reply but you can use the below syntax as it worked with me just fine  Camera  Button findViewById R id CameraID   Camera setOnClickListener new OnClickListener               Override         public void onClick View v                   TODO Auto-generated method stub             Intent Intent3 new   Intent MediaStore INTENT ACTION STILL IMAGE CAMERA               startActivity Intent3
