Share NativeModule error

How-to Discussions

I’m trying to create a module to share simple data such as this link. I don’t get any errors when I compile with the following code:

using Fuse;
using Fuse.Scripting;
using Fuse.Reactive;
using Uno.UX;

using Uno.Compiler.ExportTargetInterop;

[ForeignInclude(Language.Java, "android.content.Intent")]
[ForeignInclude(Language.Java, "com.fuse.Activity")]
[UXGlobalModule]
public class Share : NativeModule
{
    static readonly Share _instance;

    public Share()
    {
        // Make sure we're only initializing the module once
        if(_instance != null) return;

        _instance = this;
        Resource.SetGlobalKey(_instance, "Share");
        AddMember(new NativeFunction("SendIntent", (NativeCallback)SendIntent));
    }

    static object SendIntent(Context c, object[] args)
    {
        SendIntent();

        return null;
    }

    [Foreign(Language.Java)]
    static extern(Android) void SendIntent()
    @{
        Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
        sendIntent.setType("text/plain");
        Activity.getRootActivity().startActivity(Intent.createChooser(sendIntent, "Share via..."));
    @}
}


<App>
    <ClientPanel>
        <JavaScript>
            var Share = require("Share");

            function share() { Share.sendIntent(); }

            module.exports = {
                share: share
            };
        </JavaScript>

        <Button Clicked="{share}" Text="SHARE" />
    </ClientPanel>
</App>

But when I click the button the application stops unexpectedly and I get this error:

Can anyone tell me what is the problem?

See this guide for up to date example of how to make a JS module. And you can compile to android with the fuse build Android -vv flag to get more verbosity.

3

Thanks Anders, the previous code was based on an example of github. I’ve updated the first message, take a look please.

4

Could you try to run with ´-vvv` to see if that give you any more details?

5

I didn’t get more details with the -vv flag :frowning:

Perhaps this is not the correct way to call the startActivity method?

6

Yeah, it seems likely that the problem is in the Java code. It can sometimes be a bit hard to tell what’s wrong but sometimes building with -DSTACKTRACE gives you more logs, or you can add some print statements in there.

7

Solved, it seems that the name of these two functions can’t be the same:

static object SendIntent(Context c, object[] args)


static extern(Android) void SendIntent()

Sorry about that.

Yes, that could lead to a conflict. I missed that one. Good luck with your project :slight_smile:

Hey all :slight_smile:

Is there anything similar for iOS?

I wanted to create a “Share this app” button, so you can send the PlayStore/AppStore Link via i.e.WhatsApp

I found some older requests, but they all are directing to using “foreign code”, which is too high for me yet

Any help would be really nice :slight_smile:

To the curious who find this thread Fuse gained sharing features a while ago, details of which can be found over here https://www.fusetools.com/docs/fuse/share/sharemodule
We hope this helps!
