Android InflateException for tag <unknown>

Question

I have an app that works on most devices we've tested, but in the few 20 beta users 2 of them get a very weird error:

10-17 08:56:56.840 24805 24846 E AndroidRuntime: Caused by: android.view.InflateException: Binary XML file line #52: Error inflating class <unknown>

And here is the XML:

<?xml version="1.0" encoding="utf-8"?>

    android:orientation="vertical"
    android:layout_width="fill_parent"

    <LinearLayout
        android:background="@drawable/bg_filters"
        android:id="@+id/category_header"
        android:visibility="gone"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:orientation="vertical">
        <!-- LINHA DE CIMA // -->
        <LinearLayout

            android:paddingLeft="10dip"
            android:paddingTop="10dip">
            <!-- LABEL 'CATEGORIA' -->
            <TextView
                android:gravity="center_vertical"
                android:layout_height="fill_parent"
                android:layout_width="wrap_content"
                android:textColor="@color/bxkBlue"
                android:text="@string/category_title_call"
                android:textSize="14dip"
                android:layout_marginRight="5dip">
            </TextView>
            <!-- NOME DA CATEGORIA -->
            <TextView
                android:gravity="center_vertical"
                android:layout_height="fill_parent"
                android:layout_width="wrap_content"
                android:textColor="@color/bxkBlue"
                android:text="Nome da categoria"
                android:textSize="14dip"
                android:textStyle="bold"
                android:id="@+id/category_name">
            </TextView>
        </LinearLayout>
        <View
            android:layout_height="1dip"
            android:layout_width="fill_parent"

    </LinearLayout>
    <ListView

        android:layout_height="fill_parent"
        android:id="@+id/apps_list_view"></ListView>
</LinearLayout>

Line 52 on the XML is the ListView at the bottom. What could be happening?

I really have no idea of how to fix this error.

EDIT:

After reading a link, I've still got no idea, but this stacktrace might help:

What is bugging me is that pretty much all the code is "internal" and not mine...

Answer 1

Check this out: InvocationTargetException on inflating an xml - android

Answer 2

I've found out the problem after looking at the cause.

Basically I was inflating a view in a AsyncTask but was doing that on the doInBackground() method, which apparently works on most devices, but not all of them.

I moved the inflate part to the onPostExecute() and it fixed the problem.

Answer 3

To fix the error:

In Manifest:

<application
        android:largeHeap="true"

In .xml file, you must remove the below code:

android:src="@drawable..
android:background="@drawable...

Because the error is out of memory error. It is good for me
