Error inflating class on external library component usage

Question

I create a simple widget that presents same data using Pie/Donut Chart (Circle Progress Bar). I wanted to use some external component so I chose:

com.github.lzyzsd.circleprogress.ArcProgress

I placed the ArcProgress component to my widget.xml, I can see it clearly in Preview tab. There is no compilation, build or any other errors. When I run application and put widget to home screen I face an exception:

W/AppWidgetHostView: updateAppWidget couldn't find any view, using error view
      android.view.InflateException: Binary XML file line #37: Binary XML file line #37: Error inflating class com.github.lzyzsd.circleprogress.ArcProgress

I think that there is some issue with gradle, because my first try was:

az.plainpie.PieView

and result was the same (but ClassNotFound was "az.plainpie.PieView" of course).

My widget.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:custom="http://schemas.android.com/tools"

              android:layout_height="match_parent"
              android:padding="@dimen/widget_margin"
              android:background="#AA000000">

            android:id="@+id/arc_progress"
            android:layout_width="100dp"
            android:layout_height="100dp"
            app:arc_bottom_text_size="10sp"
            app:arc_progress="55"
            app:arc_bottom_text="VALUE"/>

        <TextView

            android:layout_weight="1"
            android:gravity="center"
            android:text="temp"
            android:textSize="@dimen/text_size_big"
            android:textStyle="bold"
            android:textColor="@color/colorWhite"/>

    </LinearLayout>
</LinearLayout>

project gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

module gradle:

apply plugin: 'com.android.application'
apply plugin: 'me.tatarka.retrolambda'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId 'pl.test.simplewidget'

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
    }
}

    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.android.support:appcompat-v7:25.3.1'
    testCompile 'junit:junit:4.12'
}

I've tried clean project, uninstall application, use different phone. My Android Studio has unchecked "Offline Work" and checked recommended "default gradle wrapper". I searched for solution but none of them solved my issue. Can you see what is wrong?

Unfortunately, you can't use those custom view in your App Widgets as in the documentation says:

Creating the App Widget layout is simple if you're familiar with Layouts. However, you must be aware that App Widget layouts are based on RemoteViews, which do not support every kind of layout or view widget.

Unfortunately, you are right! Now I remember that I read that doc, but I just forgot about the exception you cited here. Thank you. – mariachi Oct 03 '17 at 19:48
