应用程序在低于 5.0(棒棒糖)的 Android API 上崩溃 [英] App crashing on Android API less than 5.0(lollipop)

问题描述

我面临的问题是我的 android 应用程序在具有 API 5.0 及更高版本的设备上运行良好，但在具有 Kitkat(4.4) 及其相应较低版本的设备上崩溃.我知道它与我的 gradle 中的构建工具有某种关系文件，但仍然无法找出问题.有人可以帮我解决这个问题.

The problem I am facing is that my android application works well on devices having API 5.0 and above but crashes on devices having Kitkat(4.4) and its corresponding lower versions.I know that its somehow related to the build tools in my gradle file,but still not able to figure out the problem.Could someone please help me out with this.

这是我的 gradle 文件，

This is my gradle file,

     buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'android'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    maven { url 'http://clinker.47deg.com/nexus/content/groups/public' }
}


android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    defaultConfig {
        applicationId "com.abc.example"
        minSdkVersion 10
        targetSdkVersion 22
        multiDexEnabled true
        versionCode 12
        versionName "1.0"
    }
    buildTypes {
        release {
            multiDexEnabled true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    android {
        packagingOptions {
            exclude 'META-INF/LICENSE'
        }
    }
    android {
        packagingOptions {
            exclude 'META-INF/NOTICE'
        }
    }
}



dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile('com.fortysevendeg.swipelistview:swipelistview:1.0-SNAPSHOT@aar') {
        transitive = true
        exclude module: 'httpclient'
        exclude group: 'httpclient'
    }

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:mockwebserver:2.3.0'
    compile 'de.hdodenhof:circleimageview:1.2.2'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.google.android.gms:play-services-maps:7.5.0'
    compile files('libs/bitlyj-2.0.0.jar')

}

在构建项目时也会出现此错误，

Also getting this error when project is built,

Caused by: java.lang.NoClassDefFoundError: com.package.R$styleable
            at com.package.widgets.StyleableTextView.<init>(StyleableTextView.java:23)

这是 StyleableTextView 类，

This is StyleableTextView class,

public class StyleableTextView extends TextView {

    public StyleableTextView(Context context) {
        super(context);
    }

    public StyleableTextView(Context context, AttributeSet attrs) {
        super(context.getApplicationContext(), attrs);
        UiUtil.setCustomFont(StyleableTextView.this, context, attrs,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView_font);
    }

    public StyleableTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context.getApplicationContext(), attrs, defStyle);
        UiUtil.setCustomFont(StyleableTextView.this, context, attrs,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView_font);
    }

}

这是 attrs 中的样式，

This is the styleable in attrs,

<resources>

    <attr name="font" format="string" />

<declare-styleable name="com.package.widgets.StyleableTextView">
        <attr name="font" />

    </declare-styleable>

</resources>

推荐答案

当您使用 multidex 时，请尝试使用 MultiDexAppication 而不是 扩展您的应用程序类>Application 并覆盖低于 5.0 的 Android 所需的以下方法(因为 5.0 及更高版本支持 multidex)

When you are using multidex , then try to extend your application class with MultiDexAppication instead of Application and override below method this required for Android below 5.0 (because 5.0 and above support to the multidex)

   @Override
    protected void attachBaseContext(Context base)
    {
        super.attachBaseContext(base);
        MultiDex.install(BaseApplication.this);
    }

并在依赖项中添加这个

编译'com.android.support:multidex:1.0.1'
