We installed the Camera Plugin for Ionic and are facing this error:

Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)' on a null object reference

We have already tried all the solutions provided at the

How can we fix it? Our (original) Manifest is:

 <?xml version='1.0' encoding='utf-8'?>

20/NOV:
To explain further, we attached the Camera call in code. First function successfully opens Gallery with specified sourceType. Second function fails with source type CAMERA in error mentioned above. We are using the plugin QR Scanner in same project, there the camera opens and is functional.

openGallery () {

let cameraOptions = {

  sourceType: this.Camera.PictureSourceType.PHOTOLIBRARY,

  destinationType: this.Camera.DestinationType.DATA_URL,      

  quality: 100,

  targetWidth: 1000,

  targetHeight: 1000,

  encodingType: this.Camera.EncodingType.JPEG,      

  correctOrientation: true

}

this.Camera.getPicture(cameraOptions)

.then(imageData => {

  this.base64Image = 'data:image/jpeg;base64,' + imageData;

err => console.log(err);});   





}



takePhoto() {

let cameraOptions = {

  sourceType: this.Camera.PictureSourceType.CAMERA,

  destinationType: this.Camera.DestinationType.FILE_URI,      

  quality: 100,

  targetWidth: 1000,

  targetHeight: 1000,

  encodingType: this.Camera.EncodingType.JPEG,      

  correctOrientation: true,

}

this.Camera.getPicture(cameraOptions)

.then(file_uri => {

  console.log(file_uri);

}, 

err => console.log(err));   





}
