How to use AndroidJavaClass.Call() to pass a ArrayList or Array

Hi all,

I've not had much experience to play around with the JNI bridge.

I previously had a problem that not being able to pass a object to a Java method and @liortal help me answer the question by adding another constructor in Java Class . http://answers.unity3d.com/questions/1237659/how-to-use-androidjavaclasscall-to-pass-a-data-obj.html#answer-form

What I need to achieve is basically pass the arraylist or array from C# to the method in the Android Java Class. Thank you.

 private AndroidJavaClass ajc;
  private AndroidJavaObject ajo;
  AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
  AndroidJavaClass videoClass = new AndroidJavaClass("com.example.sdk.VidoSchema);
  
  ajo = jc.GetStatic<AndroidJavaObject>("currentActivity"); 
  ajc = new AndroidJavaClass("com.example.sdk.ExampleSDK");

Now I can pass the object to Java class by this:

 private AndroidJavaObject obj = new AndroidJavaObject ("com.example.sdk.VidoSchema", "1", "2","3","4","5");
 ajc.CallStatic ("lanuchSDKMethod", ajo, SERIAL, obj);

Above code will call this method in java:

  public static void lanuchSDKMethod(Activity activity, String serialKey, VidoSchema obj) {
        ...
        ...
      }

My question is: How to pass the arraylist or array of this VidoSchema object?

 AndroidJavaClass VidoSchema = new AndroidJavaClass ("com.example.sdk.VidoSchema");
 
 ArrayList <VidoSchema> arraylist = new ArrayList ();
 arraylist.add(obj1);
 arraylist.add(obj2);
 
 
     ajc.CallStatic("lanuchSDKMethod", ajo, SERIAL,arraylist);

In java ExampleSDK file, I have methods:

 public static void lanuchSDKMethod(Activity activity, String serialKey, ArrayList<VidoSchema> cArrayList) {
        ...
        ...
      }

This is the data structure class:

  public class VidoSchema implements Parcelable {
  
          public boolean isEntryVideo;
          public String branchId;
          public String video_location;
          public String xml_location;
          public String subtitle_location;
          public String assets_folder;
  
          public VidoSchema(Parcel in) {
              isEntryVideo = in.readByte() != 0x00;
              branchId = in.readString();
              xml_location = in.readString();
              subtitle_location = in.readString();
              assets_folder = in.readString();
          }
  
          public VidoSchema() {
          }
 
         public VidoSchema(boolean isEntryVideo, String branchId,
                        String video_location,
                           String xml_location, String subtitle_location,
                           String assets_folder) {
         this.isEntryVideo = isEntryVideo;
         this.branchId = branchId;
         this.video_location = video_location;
         this.xml_location = xml_location;
         this.subtitle_location = subtitle_location;
         this.assets_folder = assets_folder;
          }
  
 
  
          @Override
          public int describeContents() {
              return 0;
          }
  
          @Override
          public void writeToParcel(Parcel dest, int flags) {
              dest.writeByte((byte) (isEntryVideo ? 0x01 : 0x00));
              dest.writeString(branchId);
              dest.writeString(xml_location);
              dest.writeString(subtitle_location);
              dest.writeString(assets_folder);
          }
  
          @SuppressWarnings("unused")
          public static final Creator<VidoSchema> CREATOR = new Creator<VidoSchema>() {
              @Override
              public VidoSchema createFromParcel(Parcel in) {
                  return new VidoSchema(in);
              }
  
              @Override
              public VidoSchema[] newArray(int size) {
                  return new VidoSchema[size];
              }
          };
      }
