Description
We noticed that logs between iOS and Android differ. On iOS, an object is printed with it's keys, so it can be inspected. On Android, it only prints
\[object Object\], requiring to manually stringify it. Unifying it would be a quick but useful improvement to the SDK.
When I tested the below, the behavior between Android and iOS were the same.
var window = Ti.UI.createWindow(); window.addEventListener("open", function(e) { Ti.API.info("@@@ e.toString(): " + e); Ti.API.info("@@@ JSON.stringify(e): " + JSON.stringify(e)); }); window.open();"[object Object". AndJSON.stringify()correctly returns a JSON of all of the object's enumerable properties on both Android and iOS. Can you give me a code snippet please? I'm curious where you're seeing the difference. Thanks.In our case, we very often log plain objects, e.g.
console.log({ hello: 'world' });On iOS, it will be displayed "kind" of stringified - at least a bit formatted (which is done by the internal iOS logging of the underlayingNSDictionaryobject). On Android, it does not attempt to show any key/values but onky the above[object Object]. I hope that can reproduce it. But still no blocker, all okay!Okay. I've confirmed that both Android and Windows return
\[object Object\]when doing the below.var table = { myBoolean: true, myNumber: 123.456, myString: "Hello World", }; Ti.API.info("@@@ table: " + table);So, the below works on Titanium for Windows. It also works in node.js too. Not sure if it's a wise idea or not, but here it is.
Object.prototype.toString = function() { return JSON.stringify(this); };JSON.stringify()the dictionary.[~jquick] That works on Android, I put it in the
ti.main.jsOh interesting. It turns out the JS minify prevents the below from working, which is used by default when doing a "development" or "production" build. When you build for Android emulator (ie: "test" build), a JS minify does not happen and the below solutions works fine.
Object.prototype.toString = function() { return JSON.stringify(this); }; var table = { myBoolean: true, myNumber: 123.456, myString: "Hello World", }; Ti.API.info("@@@ table: " + table);
