Custom filtering of intent chooser based on installed Android package name
android, android-intent
Solution
The only one additional parameter for the chooser is `Intent.EXTRA_INITIAL_INTENTS`. Its description is:
A `Parcelable[]` of Intent or `LabeledIntent` objects as set with `putExtra(String, Parcelable[])` of additional activities to place a the front of the list of choices, when shown to the user with a `ACTION_CHOOSER`.
I haven't found any way in Android sources to exclude other activities from the list, so it seems there's no way to do what you want to do using the chooser.
EDIT: That's really easy to find out. Just check ChooserActivity and ResolverActivity source code. These classes are rather small.
Problem
I'd like to leverage the built-in intent chooser to display a custom filtered list of apps for user to select from and launch. I know how to get a list of installed packages: ``` final Intent myIntent = new Intent(android.content.Intent.ACTION_MAIN); List<ResolveInfo> resInfoList = getPackageManager().queryIntentActivities(myIntent, 0); ``` At this point I want to filter the list based on a specific string (or variation of strings) contained within the package name, which I can figure out how to do as well. But here's where I get stuck. As far as I know, `Intent.createChooser()` takes only a single target Intent as a parameter. I was hoping there was an overload that took a list of intents based on package and class names or something. But I don't see anything like that. Did I miss that somewhere? So the question is, is this possible to do with a built-in chooser, or do I have to construct my own with AlertDialog Builder? I'm hoping to avoid the later. Thanks in advance.
