Answer 1

rendering failed in Android Studio android.support.v7.widget.AppCompatImageView

Environment I was working on:
Android Studio 3.0.1

Cause was found to be in app/build.gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24           -----> 1
    buildToolsVersion "24.0.0"     -----> 2

    defaultConfig {
        applicationId "com.example.some_project"
        minSdkVersion 15
        targetSdkVersion 24        -----> 3
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:24.0.0'        -----> 4
}

I changed some of the respective lines to be as follows:

compileSdkVersion 26                       <------------ 1
buildToolsVersion "26.0.3"                 <------------ 2

targetSdkVersion 26                        <------------ 3

compile 'com.android.support:appcompat-v7:26.1.0'  <---- 4

And I didn't need to change anything in the styles.xml file. Most of the answers above had suggested to change following line:

<style name="AppTheme" parent="Theme.AppCompat.Light">

into following:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light">

But I didn't want to do it. It seems like that, Google Android has moved the Theme(s) API from Base package to a more root package, when they have upgraded the API.

Answer 2

I solved the issue by upgrading the gradle plugin version to 3.0.0-alpha2 and using gradle wrapper gradle-4.0-milestone-1-all.zip.

I logged the issue in android studio issue tracker - https://issuetracker.google.com/u/1/issues/62251892

Answer 4

I'm facing same issue when i tried autofill. but This will working for me. Make sure you add these dependencies:

compile "com.android.support:support-core-utils:26.0.0-beta2"
compile "com.android.support:support-v4:26.0.0-beta2"
compile "com.android.support:support-v13:26.0.0-beta2"
compile "com.android.support:appcompat-v7:26.0.0-beta2"
compile 'com.android.support:design:26.0.0-beta2'

and

classpath 'com.android.tools.build:gradle:2.3.3'                  

Answer 5

I also have this problem, solved as follows: modify the appcompat-v7:26.0.0-beta2 on build.gradle (modle:app) to appcompat-v7:26.0.0-beta1.

Answer 6

Dude I'm also having same issue using Android Studio 3.0, I got an solution by just make some changes in style file under the value folder of res.

Here it is...

<!-- Base application theme. -->
<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

I have added "Base." in parent to make it work properly!
