I know this thread is old  but still answering it so that no-one else should spend sleepless nights   I was refactoring an old project  whose layout files all contained hardcoded attributes such as android maxLength   500  So I decided to register it in my res dimen file as  lt dimen name  max length  gt 500 lt  dimen gt    Finished refactoring almost 30 layout files with my res-value  Guess what  the next time I ran my project it started throwing the same InflateException   As a solution  needed to redo my all changes and keep all-those values as same as before   TLDR    step 1  All running good   step 2  To boost my maintenance I replaced android maxLength   500 with  lt dimen name  max length  gt 500 lt  dimen gt  and android maxLength    dimen max length   that s where it all went wrong crashing with InflateException    step 3  All running bad  step 4  Re-do all my work by again replacing android maxLength    dimen max length with android maxLength   500 Everything got fixed   step 5  All running good

I know it is an answered question  but I do not see the cause that I faced   It was that Android Studio placed my drawables in  drawable-V24 My emulator is API 23  So  eventually it can not find it   The solution was to move all drawables to  drawable folder  no -24

I found the same error  and it took two days to identify what the error was   The error was simply because I was trying to use  android background  Rather than  app srcCompat  in an SVG file   In your case  I believe this is it   lt ImageView      android scaleType  fitXY       android layout width  fill parent       android layout height  fill parent       android src   drawable tour 11        lt -- the error is here      gt    I recommend using it this way  add this to your build gradle app  android        defaultConfig          vectorDrawables useSupportLibrary   true                and    lt androidx appcompat widget AppCompatImageView   lt -- use   AppCompatImageView   not   ImageView           android scaleType  fitXY           android layout width  match parent           android layout height  match parent           app srcCompat   drawable tour 11         gt    I hope this helps

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

For me  the error message was actually insufficient in the log cat  so here s what I did to figure out what caused the problem    In the log cat error message  it said the error occurred while inflating a specific layout in my HomeFragment java      I put a breakpoint just before the layout was inflated I ran the application in debug mode until it reached that specific breakpoint I selected the line with my cursor and ran Evaluate expression on it     Run  gt  Evaluate Expression or alt - F8  The result showed me more information about the source of the problem  which in my case  was a drawable file using tools targetApi  lollipop   the bug only occurred on older devices

I also faced a similar issue  While for anyone this may be an issue of various bad usages in Code such as   Wrong Layout tag in XML Loading of heavy resource directly into ImageView resulting in OOM Issues with usage of styles    One most ignored factor may be usage of correct Context while inflating views  Please check that you are not using ApplicationContext where an Activity context is required  While  ApplicationContext may not end up in error always  but depending upon your view hierarchy it may be crucial   I resolved my issue with a BAD context  using ApplicationContext instead of Activity in a span of 4 days  So try if that solves  Happy Coding

I had the same error on Kitkat which was because i had android tint on one of the imageViews  It would work fine on Lollipop but crash on Kikkat with Error Inflating class   Fixed it by using app tint on the AppCompatImageView which i was dealing with

User · Answer

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 these 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 all your image drawables is just the minimum necessary for your layout

User · Answer

You should copy the image files from the  drawable-24  folder to the  drawable  folder
