Ionic 2应用程式当机

Question

I am selecting images through Cordova image picker plugin and converting them to base64 string. After that, I clear the temp images on android which was generated by plugin. Everything works fine; all temporary images get removed but after that the application crashes(not crashes natively, just go to background and reintialize when resumed again) sometimes . Even when there is no processing or any function call after that. Is there any way I could trace why it is happening because no line of code is there to execute after cleaning those temp files.

Answer 1

According to the Documentation in https://github.com/Telerik-Verified-Plugins/ImagePicker

If Base64 Strings are being returned, there is nothing to clean up.

May be you don't have to clean up at all.

Answer 2

Add camera plugin to your app ionic plugin add cordova-plugin-camera Then in ts file use the following code

  takePicture() {
    var options = {
      sourceType: Camera.PictureSourceType.CAMERA,
      destinationType: Camera.DestinationType.DATA_URL
    };
    Camera.getPicture(options).then((imageData) => {
      this.base64Image = 'data:image/jpeg;base64,' + imageData;
      this.photoTaken = true;
      this.photoSelected = false;
    }, (err) => {
      // Handle error
    });
  }

In html use this

<ion-col>
  <button ion-button (click)="takePicture()">Edit</button>
</ion-col>
  <ion-col>
    <img [src]="base64Image" *ngIf="base64Image" />
  </ion-col>

this will directly give base64 image
