android - WallpaperManager leaking memory

Question

I am using leakcanary detect memory leaks on Android. First time using WallpaperManager. I don't know if you recycle or clean the WallpaperManager on destroy.

val wallpaperManager = WallpaperManager.getInstance(this)
wallpaperManager.setStream(file.inputStream())

I think these two lines of code are causing this issue, because if I comment these two lines the memory leak is not occuring.

private fun setWallpaper() {
    val dir = getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS)!!.absoluteFile
    val file = File("$dir${File.separator}wallpaper.jpg")
    val wallpaperManager = WallpaperManager.getInstance(this)
    wallpaperManager.setStream(file.inputStream())

    toast(getString(R.string.wallpaper_set_successfully))
}

Answer 1

Try calling WallpaperManager.getInstance(this.getApplicationContext());

This definitely looks like a bug in AOSP and you should file a ticket, but in the meantime using the app context should avoid the leak.
