Undefined is not an object (evaluating 'ImagePickerManager.showImagePicker') on Android

Description

Hello I’m trying to use react native image picker but I get this error. I import that by require js and I have no problem with logging console.log(ImagePicker.showImagePicker) it would show: function showImagePicker(options, callback) { if (typeof options === 'function') { callback = options; options = {}; } return ImagePickerManager.showImagePicker(babelHelpers.extends({}… but when i call that as a function i get undefined is not an object. note that i’m using wix react native navigation and my MainActivirt extends splashActivity and as it have written in Readme ( If MainActivity is not instance of ReactActivity, you will need to implement OnImagePickerPermissionsCallback to MainActivity ) my MainActivity is like code below

How to repeat issue and example

import com.reactnativenavigation.controllers.SplashActivity;
import com.imagepicker.permissions.OnImagePickerPermissionsCallback;
import com.facebook.react.modules.core.PermissionListener;

public class MainActivity extends SplashActivity implements OnImagePickerPermissionsCallback {
  private PermissionListener listener;
  @Override
  public void setPermissionListener(PermissionListener listener)
  {
    this.listener = listener;
  }

  @Override
  public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults)
  {
    if (listener != null)
    {
      listener.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
  }
}

I was struggling with this problem as well, so here is what worked for me. I am using wix/react-native-navigation routing, so my MainApplication is not the default config, hence the normal config didn’t work.

Turns our I needed to add new ImagePickerPackage() to createAdditionalReactPackages().

Here is my complete working MainApplication.java file: gist: MainApplication.java

I just got this issue. It seems you need to rebuild after linking. Just call react-native run-ios/android after calling react-native-link
