Error inflating class fragment when Run app second time

Question

I tried following solutions no one worked for me.

1) When inflating fragment which was previously inflated app crashes

2) android.view.InflateException: Binary XML file line #20: Error inflating class fragment there are no nested fragments I think

I am getting crash Error inflating class fragment when I run app after finishing 1st time.

When Open App first time everything is fine. When open app for second time crash. and when open 3rd time then app working fine. and so on.

Following is the code of my Activity having fragments

<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <!--
         As the main content view, the view below consumes the entire
         space available using match_parent in both dimensions.
    -->

    <FrameLayout

        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!--
         android:layout_gravity="start" tells DrawerLayout to treat
         this as a sliding drawer on the left side for left-to-right
         languages and on the right side for right-to-left languages.

    <!--
         The drawer is given a fixed width in dp and extends the full height of
         the container.
    -->

    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Forward the new configuration the drawer toggle component.
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    private ActionBar getActionBar() {
        return ((ActionBarActivity) getActivity()).getSupportActionBar();
    }

    /**
     * Callbacks interface that all activities using this fragment must implement.
     */
    public static interface NavigationDrawerCallbacksLeft {
        /**
         * Called when an item in the navigation drawer is selected.
         */
        void onNavigationDrawerItemSelectedLeft(int position);
    }
}

It is `mDrawerLayout.closeDrawer(mFragmentContainerView);`. NullPointerException is because of inflating error. — Ahmed Nawaz, May 28 '14 at 06:58
It is in `setUp` function. I updated question with code of `NavigationDrawerFragmentLeft.java` file. — Ahmed Nawaz, May 28 '14 at 07:01
@Raghunandan in `MainActivity's` `onCreate` function. Code of `MainActivity` is in Question. — Ahmed Nawaz, May 28 '14 at 07:05
@Raghunandan yes `mDrawerLayout` is null because Error occur before setup function called in `MainActivity's` `onCreate` function. — Ahmed Nawaz, May 28 '14 at 07:07
you are calling the method too soon. `mDrawerLayout` is null. re-think your design — Raghunandan, May 28 '14 at 07:07
When I run app 1st time is works without problem. I am facing problem when I open it second time. — Ahmed Nawaz, May 28 '14 at 07:10
check if `getActivity()` returns null. You will know yourself. good luck — Raghunandan, May 28 '14 at 07:11
On running second time an exception occur inside `setContentView(R.layout.activity_main);` :/ — Ahmed Nawaz, May 28 '14 at 07:25
When I used `System.exit(0);` in `finish()` function It works fine. I think there is some cleaning problem. Can some one tell me which things I have to clean in `finish()` function? — Ahmed Nawaz, May 28 '14 at 07:50
`System.exit(0)` itself is wrong. I can't comment any further. A quick google search should give you a clue — Raghunandan, May 28 '14 at 07:53
I just tried `System.exit(0);` to confirm there is some cleaning problem. Thanks for your help @Raghunandan — Ahmed Nawaz, May 28 '14 at 07:54
Problem solved by adding this line in `finish()` `NavigationDrawerFragmentLeft.mDrawerLayout = null;` because `mDrawerLayout` was static. — Ahmed Nawaz, May 28 '14 at 12:46

You can try to replace this line :

   `android:name="com.taazi.Fragments.NavigationDrawerFragmentLeft"`

With

class = "com.fragment.NavigationDrawerFragment"

Welcome to the site! Thanks for your answer. If you could please edit it and explain what the code you're suggesting does, and why/how that code answers the question, it would make your answer even more helpful. – Lea Cohen Mar 16 '15 at 06:30
