Error inflating class android.support.v7.widget.ContentFrameLayout

Question

Trying to add this file to my app, and I'm getting the following error:

android.view.InflateException: Binary XML file line #25: Binary XML file line #3: Error inflating class android.support.v7.widget.ContentFrameLayout

Here is the file:

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
    <android.support.v7.widget.ContentFrameLayout android:id="@id/action_bar_activity_content" android:layout_width="match_parent" android:layout_height="match_parent" android:foreground="?attr/toolbarId" android:foregroundGravity="top|fill_horizontal"></android.support.v7.widget.ContentFrameLayout>
</merge>

build.gradle

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"

    defaultConfig {
        applicationId "com.example.joestox.fakeaddwevibe"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
}

Do I need to add something like android.support.v7.widget to my dependencies? How would I go about doing this?

Check [my answer](http://stackoverflow.com/a/38164694/2720553) and see if that works. — Rohit Arya, Jul 02 '16 at 21:40
Hmm @RohitArya I just get a `Binary XML file line #3: Error inflating class ` with that solution now. — natsuki_2002, Jul 02 '16 at 21:52

I suspect ContentFrameLayout is meant for internal use. Looking at its source it doesn't really seem to do anything and the entire class is marked as @hide which is probably why you get the error (assume you already add the dependency in your apps build gradle). While I'm sure the class has some I internal purpose for the appcompat library. For the app developers, we should probably stick to using regular FrameLayout.

I've added the build.gradle file to my question. Has the dependency been added? I'm new to this. – natsuki_2002 Jul 02 '16 at 20:01
I agree to Ali (but I am not very sure about it though). @JoeDanger why don't you try replacing `ContentFrameLayout` with `FrameLayout` and I think it will serve your purpose. – Rohit Arya Jul 02 '16 at 20:08
Hmmm same error, @RohitArya `Error inflating class android.support.v7.widget.FrameLayout`. Do you think I'm missing a dependency? – natsuki_2002 Jul 02 '16 at 20:16
@Ali is right. You should not use `ContentFrameLayout`. http://stackoverflow.com/questions/17035271/what-does-hide-mean-in-the-android-source-code – Rohit Arya Jul 02 '16 at 20:17
@JoeDanger, can you try cleaning and rebuilding the project. – Rohit Arya Jul 02 '16 at 20:18
@RohitArya Ok tried cleaning and rebuiding, but still getting the same error. With the additional info: `Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v7.widget.FrameLayout" on path: DexPathList[[zip file "/data/app/com.example.joestox.fakeaddwevibe-1/base.apk"],nativeLibraryDirectories=[/data/app/com.example.joestox.fakeaddwevibe-1/lib/x86, /vendor/lib, /system/lib]]` I feel like I'm still missing something. – natsuki_2002 Jul 02 '16 at 20:23
