Complete event doesn't fire on Android

[3rror404]

Using the following example, the task complete event never fires.

function uploadImage(filePath) {
    var request = {
        url: "http://httpbin.org/post",
        method: "POST",
        headers: {
            "Content-Type": "application/octet-stream",
            "File-Name": "Test.png"
        },
        description: "{ 'uploading': " + "Test.png" + " }"
    };

    var task = session.uploadFile(filePath, request);
    task.on("progress", logEvent);
    task.on("error", logEvent);
    task.on("complete", uploadComplete);

    function logEvent(e) {
        console.log("----------------");
        console.log('Status: ' + e.eventName);
        if (e.totalBytes !== undefined) {
            console.log('current bytes transfered: ' + e.currentBytes);
            console.log('Total bytes to transfer: ' + e.totalBytes);
        }
    }

    function uploadComplete() {
        console.log('Upload complete');
    }
}

I see some progress updates in the console and I receive a local notification but the uploadComplete function is never called.

The same code works fine on iOS.

Hi @3rror404,
I reviewed your issue and found that this problem could be reproduced, when you try to upload image with large size. We will research, what is causing this problem for Android. Regarding to that I am attaching link to a sample project, where the problem could be reproduced.

Was this ever fixed? I'm still having the same problem on Android.

Hi @nraboy,
I have to confirm that this is still a real issue. We will research the reason for this problem and will verify, whether this is something related to android-upload-service. Unfortunately, I cannot commit to an exact time frame when this will be ready.

This plugin is working for me very well, firing the Complete Event, uploading images 7 to 8 MB size, is this issue related to bigger files only???

[nraboy]

To be clear, it is uploading fine for me, however, the complete event is not firing for me. This is the case for uploads of any size, big or small. It isn't particularly useful if I don't know the upload has finished.

I have been testing on Android 6.0 if that makes a difference.

Best,

+1, android only fires the error event for myself.

Please see #89 for more information about this issue. It seems the problem is with the https://httpbin/post test service itself. The response it sends back is too large when you upload large files and it cannot be handled correctly. If you test with another service that just responds with "File uploaded OK" or something similar, the complete event should fire as expected.

Hi, I had the same error that the complete event was not triggered.
I was able to fix it by setting the statusCode to 200 in my server, as soon as the file has successfully been uploaded.

For example:

app.post("/upload", function(req, res){
    // .. Upload stuff and file saving
    // as soon as the file is uploaded
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('OK\n');
});
