The exception android view InflateException  Binary XML file line       Error inflating class fragment might happen if you manipulate with getActivity   inside your fragment before onActivityCreated   get called  In such case you receive a wrong activity reference and can t rely on that   For instance the next pattern is wrong    Override public View onCreateView LayoutInflater inflater  ViewGroup container           Bundle savedInstanceState         final View view   inflater inflate R layout     container  false        Button button   getActivity   findViewById R id          button setOnClickListener       - another problem  button is null      return view      Correct pattern  1   Override public View onCreateView LayoutInflater inflater  ViewGroup container           Bundle savedInstanceState         final View view   inflater inflate R layout     container  false        Button button   view findViewById R id          button setOnClickListener            return view      Correct pattern  2   Override public void onActivityCreated Bundle savedInstanceState        super onActivityCreated savedInstanceState        Button button   getActivity   findViewById R id          button setOnClickListener

Could you post the fragment s onCreate and onCreateView methods  I had exactly same exception which was caused by an exception in the fragment onCreate method  when I fixed that problem it fixed the Error inflating class fragment

User · Answer

My simple approach  If you use  lt fragment gt  in your xml then you must provide name attribute i e           lt fragment          android name  path to your fragment           gt     which will initialise your fragment and you don t need to do it from java   If you want to use Java approach to add fragment then  use any layout like   lt LinearLayout    android id    id fragment container     gt    and use this container for your fragment  transaction replace R id fragment container  fragment obj

If your TaskDetailsFragment extending android app Fragment  do change in  onCreateView     Return your view which you want to show in the Fragment or convert your Layout to view by using LayoutInflater and return it     Override public View onCreateView LayoutInflater inflater  ViewGroup container  Bundle savedInstanceState        View mainview   inflater inflate R layout main  null       return mainview      Hope this works

In your xml file just use a  instead of the  tag  The inflater tries to create an  android app Fragment from  which will fail on API  lt  10  So you need to create a view group of a different type

Make sure your Activity extends FragmentActivity

If you have separate layout files for portrait and landscape modes and are getting an inflation error whenever you change orientation after clicking an item  there is most likely a discrepancy between your layout files   When you get the error  is it only when you click the item in landscape mode or only in portrait mode or both  Does your TaskDetailsFragment activity use a layout file that could have discrepancies between landscape and portrait modes

My problem in this case was a simple instance of having a dumb null pointer exception in one of my methods that was being invoked later in the lifecycle  This was causing the  Error inflating class fragment  exception for me  In short  please remember to check the further down the exception stack trace for a possible cause   Once I resolved the null pointer exception  my fragment loaded fine

Make sure there is no exception raised in the onCreateView method of the fragment  If any exception is raised in this method  logcat won t show exact details of the exception  instead it always shows the message    Caused by  java lang ClassNotFoundException  Didn t find class  android view fragment   on path  DexPathList  zip file   data app com package base apk    nativeLibraryDirectories   data app com package lib arm64   vendor lib64   system lib64   at dalvik system BaseDexClassLoader findClass BaseDexClassLoader java 56

If your fragment is a List Fragment then the activity which uses that fragment must implement the onFragmentInteraction interface

I was receiving this error in android studio the problem was that my fragment had a relative layout while the code on the OnCreateView function was  mDrawerListView    ListView  inflater inflate                  R layout fragment navigation drawer  container  false     is your code doing the same thing

Fragments cannot be nested in XML  Learnt this the hard way - if you nest an XML layout based  lt fragment gt  tag inside a  potentially  dynamically loaded fragment from FragmentManager  then you start to get weird errors  trying to inflate your fragment xml   Turns out  that this is not supported - it will work fine if you do this through purely the FragmentManager approach   I was getting this problem because I was trying load a fragment inside a  lt DrawerLayout gt  from xml  and this was causing a crash in the onCreateView   method when I popped the back stack

User · Answer

If you are adding Fragment statically that is  in xml  then you might have missed to implement OnFragmentInteractionListener in your Activity class  Then the interface implementation would solve the problem  If you are adding Fragment dynamically  that is  in java class then this is not the solution  Because IDE itself will not allow you to proceed without implementing required interfaces

As hdemirchian said  make sure to use   import android support v4 app Fragment    And also make sure that the Activity that is using the fragment s  extends FragmentActivity instead of the regular Activity    import android support v4 app FragmentActivity    to get the FragmentActivity class

I was receiving this error for different reasons   Steps to reproduce      My issue was that I created a brand new blank application       I then generated a custom fragment from the File    New File Menu       Proceeded to customize the fragment by adding layouts and buttons etc      Referenced the new custom fragment in the auto generated activity my xml that was generated for me when creating the application  Doing this allowed the XML to generate the objects for me    Heres is the catch when generating the custom fragment via File    New File Menu it auto generates an interface function stub and places it at the bottom of the fragment class file    This means that your MyActivity class must implement this interface  If it does not then the the above error occurs only when referencing the fragment from xml  By removing the reference for the Fragment in the XML completely  and creating the fragment through code in the MyActivity java class file Logcat generates a more concise error explaining the issue in detail and complaining about the interface  This is demonstrated in the Project Template Activity Fragment  Although   lt  that Project Template does not generate the interface stub

Had the same error type  where exactly the same error message in logcat was displayed  I needed to make changes in the Java Build Path located under Project- gt Properties  I had included Google Maps related libraries like android-support-v4 jar and google-play-services jar  however I was missing including these on the  Build class path  in the  Order and Export  option menu  Maybe the error lies here    Try including libraries to the build class path    The order of which the classes are built might also trigger the error  so my advice is also to try to rearrange the order of the building path  The error disappeared when I used the following order   my project name src - gt  my project name gen - gt  Android Private Libraries   The last unit contains the jar files mentioned earlier

If you want to inherit the AppCompatActivity  then you can do something like this- In the activity xml  use a FrameLayout like this-   lt FrameLayout     android id    id result fragment      android layout width  match parent      android layout height  match parent      android layout below    id progress frame   gt    and in the activity onCreate-  final FragmentManager supportFragmentManager   getSupportFragmentManager        FragmentTransaction ft   supportFragmentManager beginTransaction        ft replace R id result fragment  fphResultActivityFragment   result fragment        ft commitAllowingStateLoss
