My app is crashing as soon as it starts. Im getting the following error:
android.view.InflateException: Binary XML file line #34: Error inflating class
I've looked at several other similar questions but none of the solutions work for me. Why is this happening? Line #34 in the error refers to the
<fragment>..</fragment>
in mainActivity.xml

Replace your FragmentOne.xml with this
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- TODO: Update blank fragment layout -->
<ListView
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="left|top" />
</FrameLayout>
Here you just needed to change the id of ListView to this
android:id="@android:id/list"
