Description

ISSUE
Selecting a large image through the plugin creates a delay before returning control to the Cordova app which uses the plugin

Current Behavior

1. Selecting a large image (in filesize) through the plugin creates a delay before returning control to the Cordova app which uses the plugin. This includes both:
   • Camera capture
   • Image gallery
2. This delay increases in a linear fashion with the filesize of the selected image

Expected Behavior

1. Selecting an image should:
   • Return control immediately to the Cordova app which uses the plugin
   • Continue the data transfer of the image to the Cordova app in a background thread
   • Include a callback function to indicate that the data transfer of the image to the Cordova app is complete
2. This includes both:
   • Camera capture
   • Image gallery
3. All image file sizes should return control to the Cordova app which uses the plugin at the same speed including:
   • 5MB image
   • 11MB image
   • 15MB image
   • 20MB image
   • 40MB image

1. # Platforms affected
   • Android
   • iOS

REFERENCES

1. Here are sample test images:
   • 5MB image
   • 11MB image
   • 15MB image
   • 20MB image
   • 40MB image
