[TIMOB-7249] Android: Intent - getData(), getAction(), and getType() do not work

Problem

When deciding how an app should handle an incoming Android Intent, knowing the type, action, and data values that were sent with the Intent are critical. If your app only handles one very specific Intent, this is OK, but if you have an app that handles images, URIs, video,, etc... you need to know these values. Right now when an Intent is received via Intent Filter in Titanium, the following lists the values/errors you will get for the data, type, and action functions and properties of an Intent: * getData() always equals null * getType() and getAction() always throw this exception, despite the fact that logic and documentation dictates that these functions do not require arguments:

Uncaught Error: Requires property name as first argument

* The data property always returns null * The action and type properties always return undefined

Proposed Solution

The above listed functions and properties need to return the appropriate values for data, type, and action so that developers will know what to do with the Android Intent that they are receiving. Like I said, if you are handling only one type of data as dictated by your Intent Filter, you are OK. But if you plan to handle images, video, etc... and you need to read them from Ti.Android.EXTRA_STREAM, you have no way of knowing which type of Intent you are receiving. Also, I believe the implementation of getAction() and getType() need to change so that they do not require a parameter.

Test Case

var win = Ti.UI.createWindow({
    backgroundColor: '#fff',
    fullscreen: false,
    exitOnClose: true
});
win.addEventListener('open', function(e) {
    var intent = Ti.Android.currentActivity.getIntent();
    var iname = Ti.Android.EXTRA_STREAM;
 
    if (intent && intent.hasExtra(iname)) {
    	Ti.API.info(intent.getAction());
    	Ti.API.info(intent.getData());
    	Ti.API.info(intent.getType());
    } else {
        Ti.API.info('No extra named "' + iname + '" found in Intent');
    }
});
win.open();

It will also be necessary to add an intent filter to a custom AndroidManifest.xml to get this test case to receive intents. The only below needs to go in the main activity and will receive all image share intents. You can easily trigger an image share intent by long clicking on an image in the android gallery then select 'share' from the intent list. Then just select your test case app from the list.

<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>
