android.view.InflateException: Binary XML file line #0: Error inflating class Button

Question

I am following a course on Audacity, and decided to type out all the code, but then I run into an error when I try run the app.

I get the following error:

Answer 1

I have got the same issue and I have resolved finally Opening the gradle.properties and added following line:

android.enableAapt2=false

Hope this helps you.

Answer 2

the button selector is the cause of the problem .. if you read the remaining of the exception, the root cause will be mentioned .. as resource id can't be found !

you have to change your button_selector.xml from:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#999999" android:state_enabled="false"/>
    <item android:color="@color/colorAccent" android:state_enabled="true"/>
</selector>

to:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="#999999" android:state_enabled="false"/>
    <item android:drawable="@color/colorAccent" android:state_enabled="true"/>
</selector>

and it will work fine isA.

Answer 3

In my case the background xmls where not inside one drawable directory. I added all of them in drawable hdpi folder and then rebuild the project. That resolved this issue.

This worked for me!

Answer 4

May be you declare the drawable file into v21 or v24 folder to change this select the button_selector.xml file go to the show in menu option file select the cut button_selector.xml file and move into the drawable folder and paste it.

Answer 5

Maybe this help anyone > I got similar crash

InflateException: Binary XML file line #0: Error inflating class EditText

in Android 8.0 and 8.1 in release apk due to xml fonts cause I didn't use latest support libs, I update support library version and it's fixed.

xml having

<EditText
        android:id="@+id/editEmail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:fontFamily="@font/sanfranciscodisplay_medium"
        android:hint="@string/enter_email_address"
        android:lines="1"
        android:inputType="textEmailAddress"
        android:layout_centerHorizontal="true"/>

My gradle configs

BUILD_TOOLS_VER = '26.0.2'

TARGET_SDK_VER = 26
MIN_SDK_VER = 19

SUPPORT_LIBS_VER = '26.1.0' -> '27.0.2' (fix here)
GOOGLE_SERVICES_VER = '11.4.0' -> '11.8.0'

Have you tried adding in gradle.properties file this line below ?

 android.enableAapt2=false

and then restarting the Gradle daemon command line by running
