If there is no issue for your problem, tell us about it

I'm downloading small video files of 2-3mb in size, using http.getFile . After each download, i can see a significant increase in memory usage. In time, this results in OOM. I'm able to trace this problem back to widgets.Async.Http.MakeRequest, but lack of java skills stops me there.

Which platform(s) does your issue occur on?

• iOS/Android/Both Android
• iOS/Android versions 7.1.1
• emulator or device. What type of device? Device: General Mobile 4G Android One

Please, tell us how to recreate the issue in as much detail as possible.

I'm simply calling http.getFile.

== app/game_state.js ==
...
gmu("getVideoFile 1");
await $http.getFile(fileurl, filePath);
gmu("getVideoFile 2");
...

== tns-core-modules/http/http.js ==
function getFile(arg, destinationFilePath) {
    return new Promise(function (resolve, reject) {
        gmu("getfile 1")
        httpRequest.request(typeof arg === "string" ? { url: arg, method: "GET" } : arg)
            .then(function (r) {
            try {
        gmu("getfile 2")

== tns-core-modules/http/http-request/http-request.android.js ==
function request(options) {
        ...
        gmu("request 8")
            org.nativescript.widgets.Async.Http.MakeRequest(javaOptions, completeCallback, new java.lang.Integer(requestIdCounter));
        gmu("request 9")
        ...
}

Memory usage logs are as follows. The significant jump happens upon widgets.Async.Http.MakeRequest resolves at "getfile 2"
