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:
E/GlanceAppWidget: Error in Glance App Widget

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:
