Android app icon loader from AOSP iconloaderlib, with optional Glide and Coil integration.
This is not an officially supported Google product.
Because PackageManager.getApplicationIcon() (or PackageItemInfo.loadIcon()) just doesn't work well with adaptive icons. Non-adaptive icons usually have some shadow baked in (it's the recommended behavior), however adaptive icons never contain a shadow themselves, so we'll need to manually add the shadow or icons with a white background will just blend into our app's own background.
This library packaged the AOSP iconloaderlib for loading app icons, which has proper shadow and badging logic, and added easy integration with Glide and Coil.
Meanwhile, by passing true for the shrinkNonAdaptiveIcons parameter, this library can also synthesize adaptive icons for apps that don't have it.
Gradle:
// For using with Glide.
implementation 'me.zhanghai.android.appiconloader:appiconloader-glide:1.5.0'
// For using with Coil.
implementation 'me.zhanghai.android.appiconloader:appiconloader-coil:1.5.0'
// For using AppIconLoader directly.
implementation 'me.zhanghai.android.appiconloader:appiconloader:1.5.0'
// For using iconloaderlib directly.
implementation 'me.zhanghai.android.appiconloader:appiconloader-iconloaderlib:1.5.0'See Glide's documentation on registering a ModuleLoader.
Inside your implementation of AppGlideModule.registerComponents(), you can have something like the following code fragment:
int iconSize = context.getResources().getDimensionPixelSize(R.dimen.app_icon_size);
registry.prepend(PackageInfo.class, Bitmap.class, new AppIconModelLoader.Factory(iconSize,
false, context));See also the sample app's AppGlideModule implementation.
After the setup above, Glide will support loading app icons with the app's PackageInfo.
GlideApp.with(imageView)
.load(packageInfo)
.into(imageView);val iconSize = context.resources.getDimensionPixelSize(R.dimen.app_icon_size)
Coil.setImageLoader(
ImageLoader.Builder(context)
.components {
add(AppIconKeyer())
add(AppIconFetcher.Factory(iconSize, false, context))
}
.build()
)After the setup above, Coil will support loading app icons with the app's PackageInfo.
imageView.loadAny(packageInfo)AppIconLoader is the API exposed by this library, and you can simply call AppIconLoader.loadIcon() to load an app icon. You can also use AppIconLoader.getIconKey() to generate a cache key for your loaded icon.
