Try this

public void onLaunchCamera(View view) {

    //btn = (Button) findViewById(R.id.button);
    if(getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA)){
         if (Build.VERSION.SDK_INT == Build.VERSION_CODES.M) {
            checkPermission();
        }
        else {
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, getPhotoFileUri(photoFileName)); // set the image file name

            if (intent.resolveActivity(getPackageManager()) != null) {
            // Start the image capture intent to take photo
            startActivityForResult(intent, 0);
            }
        }
    } else {
        Toast.makeText(MainActivity.this, "No Camera",
                Toast.LENGTH_LONG).show();
    }
}

private void checkPermission() {
            if (ContextCompat.checkSelfPermission(this,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this,
                    Manifest.permission.CAMERA)
                    != PackageManager.PERMISSION_GRANTED) {//Can add more as per requirement

                ActivityCompat.requestPermissions(this,
                        new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                        123);

            } else {

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT,getPhotoFileUri(photoFileName)); // set the image file name     

           if (intent.resolveActivity(getPackageManager()) != null) {
           // Start the image capture intent to take photo
           startActivityForResult(intent, 0);
             }
          }

And make sure you have set proper version in your build.gradle

    **compileSdkVersion 23
    buildToolsVersion "23.0.2"**

    defaultConfig {
        applicationId "your_package_name"
        minSdkVersion 15
        **targetSdkVersion 23**
        versionCode 1
        versionName "1.0"
        multiDexEnabled true

    }
