Crash in glance app widget image when trying to display bitmap

Question

When I try to display a bitmap image (of my app icon) in the app, it works ok, but crashes when I try to display it in Widget Glance.

This is my code for bitmap:

    val icon = packageManager.getApplicationIcon("com.myapp.packagename")
    val bitmap: Bitmap = try {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            getAppIconV26(applicationContext, "com.myapp.packagename")
        } else {
            (icon as BitmapDrawable).bitmap
        }
    } catch (e: Exception) {
        (ResourcesCompat.getDrawable(applicationContext.resources, R.drawable.placeholder, null) as BitmapDrawable).bitmap

And this is jetpack compose Image, which loads bitmap fine:

androidx.compose.foundation.Image(
    modifier = Modifier.size(46.dp), 
    bitmap = bitmap.asImageBitmap(),
    contentDescription = null),
}

but when I try to load the same bitmap in the widget using Jetpack Glance Image, the widget crashes:

androidx.glance.Image(
    modifier = GlanceModifier.size(46.dp),
    provider = ImageProvider(bitmap),
    contentDescription = null,
)

Crash:

I don't understand this crash. Can somebody please help me understand what's wrong?

Glance translates into actual RemoteViews. Those are then passed to the host process (i.e the launcher/homescreen). There is a limitation in the size of the object that can be passed between process.

It seems you are using a LazyColumn (thus a ListView) that displays many Bitmaps. It could be that you hit that size limit.

Couple of things to try:

Try displaying just one with the same code
- Does it work?
- Does it work if you pass another small Bitmap? Maybe the issue is with the bitmap size or type?
Alternatively try using URIs instead of bitmaps or limit the number of items to be displayed.

I used this png: ibb.co/MnqFPWC, with GlanceModifier.size(42.dp) in my test. I was able to display the Image. I was also able to create a Column(GlanceModifier.fillMaxSize().background(widgetBackground)) with 10 Images (but column can't be scrolled). I wasn't able to create a LazyColumn(GlanceModifier.fillMaxSize().background(widgetBackground)) with even just one Image, it produced the same error. – Blank空白 Jan 26 '22 at 13:44

I tried to extract app icons with Uri.parse("android.resource://${myapp.packageName}/${myapp.icon}"). Then I tried to display Image with that uri, and it worked. It also worked with LazyColumn, even if I displayed 30 items. Thanks!!! This was tested on Pixel 5, I will also try older devices. – Blank空白 Jan 26 '22 at 13:59
@Blank空白 could you please provide how you implemented your solution? – mars8 Apr 19 '22 at 08:40

@mairs8 Image(modifier = GlanceModifier.size(42.dp), provider = ImageProvider(Uri.parse("android.resource://${packageName}/${appInfo.icon}")), contentDescription = "App icon") – Blank空白 Apr 19 '22 at 09:47
@Blank空白 Thanks, I have tried something similar with `getUriForFile( context,"${context.packageName}.fileprovider", filename)` but the widget is only showing a "loading..." message. Have raised a separate question on it https://stackoverflow.com/q/71938442/15597975 – mars8 Apr 20 '22 at 11:02
@Marcel can you please elaborate on "try using URIs instead of bitmaps"? The LazyColumn does not work with any Bitmap. I am trying to pass a png file that I have saved via URI but I that does not seem to work either. The only working URI examples I have seen are those that point to an android resource. Please help. stackoverflow.com/q/71938442/15597975 – mars8 May 08 '22 at 19:14
Unfortunately it's not trivial. Have you provide read access to the file? Check https://developer.android.com/training/secure-file-sharing – Marcel Jun 08 '22 at 03:36
Same Here. LazyColumn + a NetworkImage (using suspend in beta01). Works great on Android13, fails with this error on Android11 even using BitmapImageProvider and right Context :/ – Jscti Jun 28 '23 at 19:35

I don't think the underlying library supports passing Bitmaps in lists, because it would be very easy to exceed the binder limit when passing the Bitmaps. You need to implement a content provider and pass uris instead of the bitmaps I think

Could you use val context = LocalContext.current instead of applicationContext? Moreover, please use BitmapImageProvider instead of ImageProvider.

+1 for the context but there is no BitmapImageProvider in Glance. The use of ImageProvider(glance) is correct – Marcel Jan 26 '22 at 03:48
Are you sure about BitmapImageProvider? I can import it with import androidx.glance.BitmapImageProvider – Enes Zor Jan 26 '22 at 07:48
This class is internal to the library and annotated as such https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:glance/glance/src/androidMain/kotlin/androidx/glance/Image.kt;l=41 – Marcel Jan 26 '22 at 11:14
Thanks for the notice about the context. I looked at the BitmapImageProvider but I don't see how that makes any difference. From what I see, ImageProvider automatically picks the right type so I don't have to manually declare it. That also didn't change anything in my error - is still the same. – Blank空白 Jan 26 '22 at 11:29
