To demonstrate how Android selects an alternative resource, assume theįollowing drawable directories each contain different versions of theīy comparing the device configuration to the available alternative On the Android Developer page for Providing Resources, there is a section that discusses the approach Android uses for selecting the best matching resources using an example where several drawable resources are available. It seems to me like a bug for the image to not display when in the only available drawable/ folder since others recommend using the drawable folder for all images that are not app icons. So putting images other than launch icons in a mipmap folder seems to work but does not follow Android convention. While putting the image into any of the mipmap folders also worked for me (and then of course changing to the Android Developer page for App Resources says that mipmap resources are for "Drawable files for different launcher icon densities". Apparently the use of three drawable folders (-hdpi, -mdpi, -ldpi) used to be standard practice. Had to move image to "mipmap-xxhdpi" folder due to sizeĪn earlier duplicate question was asked (I don't have enough points to flag the question above as a duplicate) here and Lukap's suggestion of putting the drawable into a drawable-hdpi folder worked for me. Why is this the case? The original image is clearly not corrupt as it shows up in Android Studio png image in the drawable folder that seems to give no problems. png format and is located in the drawable folder.
I'm new to the Android development scene so go easy on me. Hence, I am finding it very hard to locate the problem. I don't see why not but it's the only thing that I could think of.īasically Android studio shows everything working but on the phone/emulator it is not the case. The one thing that I was unsure of was whether I could use relative view when defining the cells for the list view in the separate xml file.
If any of this is possibly interfering then I will post the code here, but I find that hard to believe. (This image view is working if it helps). It consists of one image view and 2 text views. However, when I run this app on my phone the List View shows with just a blank image (i.e - a space) above it where the "somewhere over the rainbow" should be.
jpgĪfter following the steps above, the files will download as normal JPGs.As you can see below this is what Android Studio shows: Check the extent parameter in image / pjpeg at the same location, it should also be set to.jfif, then double-click the parameter and enter. In the right pane of the registry editor, notice the value of the parameter named Extension.
The same can happen when saving images in Windows 11 programs. The most common question about JFIF comes from users who download photos and other images from the Internet and suddenly start to download in JFIF format, even though they are posted in plain JPG.
What to do if photos from the Internet are downloaded in JFIF format in Windows 11 and Windows 10 If the file is intact, after changing the extension from JFIF to JPG, it will open correctly where needed like any other JPEG image. Once the extensions are enabled, simply change the file extension from JFIF to JPG. Universal method: open the Control Panel (you can use the Windows 11 and Windows 10 search to do this), change the Control Panel view to "Icons" (in the "View" field at the top right) and open " Explorer Preferences ", then in the" View "tab uncheck" Hide extensions for registered file types "and apply the settings. If the system does not display the extensions (that is, you only see the file name before the period), turn on the display of extensions for registered file types in the browser options.If you have file extensions on your system, right-click on the JFIF file, select "Rename", change the file extension after the dot to JPG, and answer "Yes" to the question "This file may not be available after changing the extension ».Since the content of the JFIF and JPG files is identical, there is no need to convert the format, just change the file extension:
