Glance is now in beta! : )

Hi! Playing around with Glance beta: The color I get from

.background(GlanceTheme.colors.background)
.appWidgetBackground()

is not the same I get from google widgets, like gmail, stocks or battery, could that be?

Hello, World! Trying Glance Tiles for the 1st time, I'm getting an exception when trying to show a simple Image:

java.lang.NoSuchMethodError: No virtual method getContentDescription()Ljava/lang/String; in class Landroidx/glance/EmittableImage; or its super classes (declaration of 'androidx.glance.EmittableImage'

Known issue?

All right now how do I display a round button with an icon on my tile (like those)?

and/or can I have my

Button

look a bit like chips ? That is, with rounded corners. At the moment my button looks like this:

Props to the glance team, I'm currently rewriting a widget since I'm getting tired of sifting through poorly written code that went in before I was around, it's actually quicker to just redo the widget in glance than to poke around. It's also extremely simple to hook in libraries like coil now that composition is supported

Overall, it looks tons better. Only thing I'm doing differently is not using the preferences impl, our data is backed in SQLite through react native async storage, they provide a brownfield coroutine impl for data access

Top is new, bottom is old

Quick Q: when updating a larger data source, will it only update if the snapshotted state definition is not equivalent? I don't use state definitions because I'm trying to avoid doing a data duplication dance with react native If this is the case, is there a way to force an update? I'm thinking of just storing the last updated timestamp in millis to force this, hacky, but would probably work. I'd like to avoid this Edit: tried this, and realized it wouldn't work! The current composition doesn't get recreated (duh).

For the record, react-native-async-storage is backed by room when using their next impl

Switching to glance immediately made the user experience better than the imperative remote views code

I still need to work out some state update stuff, and maybe consider using the state definition system for some aspects, but we already have enough data duplication related tech debt that we're taking on and I'd prefer not to use that

The old widget is also still stuck in this state minutes later 🤣

Hello everyone, is there any plan to add animations to Glance? Even a simple crossfade would be super appreciated 😁

@Marcel Pinto Hi, do you have any plan to support custom notifications through Glance? Since it is also kind of RemoteViews..

Hello everyone! I'm developing a widget that must be updated based on the user interaction with the app, I've noticed that the updateAll function of the widget doesn't work every time it's called, so the widget doesn't get updated every time I call that method, but if I kill the app, reopen it and interact with the screen that calls that method, the method does update the widget (I've also tried to update the specific widget using the ID and get the same results). Is this an expected behavior?

@Marcel Pinto Hi, I have one more question. Does Google have any plan to support Glance Preview in Android Studio like Compose?

@Marcel Pinto I am working on creating widgets for 2x1, 3x2, 4x2 and 5x2 sizes. Could you throw some light on how these map to the Dp sizes in the devices. Since every device has a different size and grid layout, how does Glance handle it ? What are the developers supposed to do to map them correctly ? (Sample code has hardcoded values)

FYI I am glad to help answer questions, but it’s better to just ask to the full community instead of specifically tagging me. If you don’t get an answer, you can then tag me or @Summers Pittman

It looks like Glance went RC 🎉 https://developer.android.com/jetpack/androidx/releases/glance#1.0.0-rc01

Anyone here use Koin? How do I inject my repository into a glance composable?

I would like to render a logo from an image url. Does Glance provide any functionality or any composable for doing the same ?

Hello everyone, is there any plan to provide a way to set various weight values at glance? Currently, only defaultWeight is supported.

Hello everyone, been really enjoying making my first Android app and using Glance. My only issue is that I realized after following the Glance Widget WeatherApp demo that I didn't understand how to make each widget have it's own datastore. I see the comments that it can be done with fileKey, but most examples on GitHub from other projects seem to use datastore-preferences instead. Is it possible to slightly modify the WeatherApp demo, keeping it's serializer and existing setup and get a unique datastore per widget? I tried:

private val Context.datastore by dataStore(fileKey, WeatherInfoSerializer)

(replaceing the default FILENAME parameter with fileKey, but as it was not yet initialized, it does not work. I'm a bit lost as to how this should be done, though the comments in WeatherApp allude to it being close. Could someone share some help? I also asked my question here in Stack Overflow: https://stackoverflow.com/questions/77008645/how-to-make-unique-datastore-for-each-glance-widget

Rename this channel to compose-glance like other compose channels

Hey guys, Glance 1.0.0 is published now! https://developer.android.com/jetpack/androidx/releases/glance#1.0.0 We'll be releasing a blog post soon (next couple of weeks) and updating our samples.

I am working on a widget that is built from the images example: https://github.com/android/platform-samples/blob/main/samples/user-interface/appwidgets/src/main/java/com/example/platform/ui/appwidgets/glance/image/ImageWorker.kt The difference is I am first calling an API and storing images to cacheDir then displays them on the widget with a "next" button to cycle through images. My problem: When the widget is stopped or the Android Studio emulator runs the app again, the widget will die. I do not see any errors in the logcat related to my app, but I do see this warning:

Permission Denial: opening provider com.thirdgate.stormtracker.ImageFileProvider from ProcessRecord{2899a4f 1117:com.google.android.apps.nexuslauncher/u0a151} (pid=1117, uid=10151) that is not exported from UID 10185

followed by a second warning:

Error inflating RemoteViews android.widget.RemoteViews$ActionException: java.lang.SecurityException: Permission Denial: opening provider com.thirdgate.stormtracker.ImageFileProvider from ProcessRecord{2899a4f 1117:com.google.android.apps.nexuslauncher/u0a151} (pid=1117, uid=10151) that is not exported from UID 10185

I think the issue it is highlighting is that the original permission was granted to the first . This is done with essentially the same code as the above example:

// Find the current launcher every time to ensure it has read permissions
val intent = Intent(Intent.ACTION_MAIN).apply { addCategory(Intent.CATEGORY_HOME) }
val resolveInfo = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
    context.packageManager.resolveActivity(
        intent,
        PackageManager.ResolveInfoFlags.of(PackageManager.MATCH_DEFAULT_ONLY.toLong()),
    )
} else {
    @Suppress("DEPRECATION")
    context.packageManager.resolveActivity(
        intent,
        PackageManager.MATCH_DEFAULT_ONLY,
    )
}
val launcherName = resolveInfo?.activityInfo?.packageName
if (launcherName != null) {
    context.grantUriPermission(
        launcherName,
        contentUri,
        FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_PERSISTABLE_URI_PERMISSION,
    )
}

How should I store the images so that the URI permissions persist across reinstalls or restarts? Is there any other way I can test this situation? As I mentioned, the whole widget appears to die, but no error logs are shown for my app in logcat.

Theoretically, could you make a chess game widget with glance?
