App restart? after photo taking or selection using native camera

Ionic Framework ionic-v3
1

Hi everyone,

I have been exploring this issue for a while. When I take a photo or select photo with the using of the native camera plugin, the app will auto reload. It happens randomly, the screen appears to be white for a while (1-3 secs) and reload. Is this the memory issue? or any other issue? Does anyone know?

Thanks in advance.

It’s how Android behave when there isn’t enough memory available

I documented the subject when I was analyzing it and developing a solution to handle restart in the following post: https://forum.ionicframework.com/t/solved-camera-plugin-restart-app-on-android

Hi,

Thanks for reply. But the solution doesn’t seem to fix mine problem. The problem is still there with my iPhone 7s Plus. Any other suggestion?

Thanks.

Oh ok, effectively what I was explaining above is only effective for Android phones

Never had this problem with iPhone

Can you add the code that your using, if the app crashes due to some reasons, then also there is chance of above issue.

Hi all, below is my camera setting,

this.photoTakingOptions = {
      quality: 90,
      allowEdit: true, 
      sourceType: this.camera.PictureSourceType.CAMERA,
      saveToPhotoAlbum: false, 
      correctOrientation: true,
      targetWidth: 1000,
      targetHeight: 1000, 
      destinationType: this.camera.DestinationType.DATA_URL,
      mediaType: this.camera.MediaType.PICTURE,
      encodingType: this.camera.EncodingType.JPEG
    } 

    this.photoLibraryOptions = {
      quality: 90,
      allowEdit: true, *
      sourceType: this.camera.PictureSourceType.PHOTOLIBRARY,
      saveToPhotoAlbum: false,
      correctOrientation: true,
      targetWidth: 1000,
      targetHeight: 1000, 
      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE
    }

I did try to debug the error, but, the app refreshes without entering any condition (success or error).


  photoTaking(id) {
    let self = this;
    this.camera.getPicture(this.photoTakingOptions).then((imageData) => {
      this.camera.cleanup().then(() => {
      })

      var file = 'data:image/jpeg;base64,' + imageData;
      self.upload(file, id);
      self.toast = this.toastController.create({
        message: "Processing ..."
      });
      self.toast.present();
    }).catch(err =>{
      console.error(err);
    })
  }

  photoLibrary(id) {
    let self = this;
    this.camera.getPicture(this.photoLibraryOptions).then((imageData) => {
      this.camera.cleanup().then(() => {
      })
      var file = 'data:image/jpeg;base64,' + imageData;
      self.upload(file, id);
      self.toast = this.toastController.create({
        message: "Processing ..."
      });
      self.toast.present();
    }).catch(err =>{
      console.error(err);
    })
  }

Thanks.

Hi Can you remove below code from photoTaking function

 this.camera.cleanup().then(() => {
      })
      var file = 'data:image/jpeg;base64,' + imageData;
      self.upload(file, id);
      self.toast = this.toastController.create({
        message: "Processing ..."
      });
      self.toast.present();

and just put a log there,

console.log(imageData)

I think

this.camera.cleanup().then(() => {
      })

is causing some issue.

Hi,

The cleanup function I just added today, this issue happened before I add the cleanup function. And it wont go into the .then function, the app just refresh after I took or select the photo. So even if I add console on .then function or catch error function, it wont be triggered.

Thanks.
