android.view.InflateException: Binary XML file line #12: Error inflating class <unknown>

I am receiving many errors of kind displayed in the subj. These errors seems to be occasional and I cannot reproduce them. From stack I can learn that such error may occurs for my different layout resources. The line of XML is also varying.

Can anybody explain why this error occurs? And what I can do to fix this problem?

    The inflate exception is not actually the problem, but really comes from another deeper issue in your layout that is then wrapped in an InflateException.
    A common issue is an out of memory exception when trying to inflate an imageview loading a drawable resource. If one of this resources has a high pixel resolution it would take a lot of memory causing then an inflate exception.

    So basically verify that the pixel resolution in your drawables images are just the minimum necessary for your layout.

    ViewFlipper loads all images into memory during layout inflating. Because my images are big it takes many memory, I replaced ViewFlipper with ImageSwitcher which can change the images with animation like ViewFlipper but it loads only one image at the time.

    This can also happen if you use a VectorDrawable using support library and forgot to use app:srcCompat instead of android:src

    Exact error is:
    Binary XML file line #XX: Error inflating class ImageView

    See that link

    I know the question is already answered but still I’m posting with thought that may someone run into this kind of problem.

    In my case problem is i’m loading my application to phone which refer layouts from res/layout/ folder and values for @dimens from res/values/dimens here it’s font_22 which it’s trying to access and it’s define in res/values-xlarge/dimens.

    I’m actually updating UI of existing project.

    I ran into this problem because I’m using IDE Eclipse where I ctrl+space for hint while writing xml for layout folder it displays all values from values as well as values-xlarge folder regardless of for which folder I’m writing.

    I also know that the values in both files should be same to mapped for different screens.

    Hope this may help someone run into this kind of silly problem.

    This link may help you. Try checking in your manifest for problems. If you can get it to happen again, post your entire stack trace so that we can see what the error actually is.

    EDIT: I’m sure you’ve checked this, but what is on line 12 of the XML file you use for the TourActivity layout?

    My picture size is only 14Kb but the problem is that the designer gave me 1011px x 1819px (resolution too high hence causing the InflateException)

    I encountered the same bug and found the root reason is:

    Use Application Context to inflate view.

    Inflating with Activity Context fixed the bug.

    I had this error because i selected theme as Material theme. But as i was trying to run app on 4.4.2 it gave this error.

    Solution : Select Theme_holo as theme

    I had the same error and I solved moving my drawables from the folder drawable-mdpi to the folder drawable. Took me some time to realize because in Eclipse everything worked perfectly while in Android Studio I got these ugly runtime errors.

    Edit note:
    If you are migrating from eclipse to Android Studio and your project is coming from eclipse it may happen, so be careful that in Android Studio things a little differs from eclipse.

    I had the same error when creating custom view with only one constructor, try to define all constructor for your custom views.

       public CustomWebView(Context context) {
        public CustomWebView(Context context, AttributeSet attrs) {
            super(context, attrs);
        public CustomWebView(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);

    I had this problem just now and managed to figure out what it was. Was referencing a colour in my values that was causing problems. So defined it manually instead of using one from the dropdown suggestions.Then it worked!

    In my case,this error happen when I use the Floating action button and set android:backgroundTint="#000". Then just don’t set backgroundTint and problem solved.
    Hope it’s helpful for you.
