离子 cordova camera.getPicture 不返回任何内容

Question

I have simple ionic app where it takes picture from cordova camera function.It goes no where from there..

Really need the help to solve this..I stuck with this from few weeks..now..

  const cameraOptions: CameraOptions =  {
      quality: 100,
      destinationType: this.camera.DestinationType.FILE_URI,
      // encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      sourceType: this.camera.PictureSourceType.CAMERA,
      saveToPhotoAlbum : true
     }
     try {
       let obj = this.camera.getPicture(cameraOptions).then((imageData) => {
    // never entered here
         console.log('getPicture Success '); 
         // let base64Image = 'data:image/jpeg;base64,' + imageData;
         let base64Image = imageData;
         this.capturedSnapURL = base64Image;
         alert(this.capturedSnapURL);
       }, (err) => {
         alert('error=' + err); // never entered
         console.log(err);
       });
      alert('no error but no picture:' + obj); // always print this [object Promise]
    } catch (error) { 
      alert('exception error' + error); //never entered here
    } 

I have been trying above code from quite sometime, it never entered success block nor in error block of then() of getPicture. Never printed 'getPicture Success' or error.
It only shows "no error but no picture:[object Promise]" message. I tried debug this also using remotedevice option in emulator. It comes in till getPicture function call and then get lost. No error or exception.

I have tried many solutions as suggested but no luck..I have upgraded ionic, angular,cordova,nodejs to latest version to resolve this issue but no luck. Here the version details

Answer 2

try something like bellow, I used this code to get a picture (file path) from the camera in an ionic app, work both in ios and android. for the camera option details, you can look here

  constructor(
    private camera         : Camera,
    private platform       : Platform,
    private imagePicker    : ImagePicker,
    private filePath       : FilePath,
  ) {}

  takePicture() {
    var options: CameraOptions =
    {
      quality             : 100,
      sourceType          : this.camera.PictureSourceType.CAMERA,
      saveToPhotoAlbum    : true,
      correctOrientation  : true,
      encodingType        : this.camera.EncodingType.JPEG,
      targetHeight        : 1000,
      targetWidth         : 1000,
    };
      
    this.camera.getPicture(options).then(imagePath => {
        if (this.platform.is('android') && sourceType === this.camera.PictureSourceType.PHOTOLIBRARY) {
          this.filePath.resolveNativePath(imagePath).then(filePath => {
            let correctPath = filePath.substr(0, filePath.lastIndexOf('/') + 1);
            let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1, imagePath.lastIndexOf('?'));
            console.log('filePath 1', filePath);
            console.log('current  1', currentName);
            console.log('correct  1', correctPath);
          });
        } else {
          let currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);
          let correctPath = imagePath.substr(0, imagePath.lastIndexOf('/') + 1);
          console.log('filePath 2', filePath);
          console.log('current  2', currentName);
          console.log('correct  2', correctPath);
        }
    }, err1 => {
      console.log('something wrong 1 -> ', err1);
    }).catch(err2 => {
      console.log('something wrong 2 -> ', err2)
    });
  }
