Question

我正在为我的Android项目使用eclipse和Dagger 1.2.2。我设法用Dagger实现了一个测试应用程序。但是对于我的＆＃34;真实＆＃34;申请我得到：

java.lang.RuntimeException：无法创建应用程序app.MyApplication：java.lang.IllegalStateException：无法加载类app.MyApplicationModule的模块适配器。请确保为此模块运行代码生成。：

这是 MyApplication.java ：

public class MyApplication extends Application implements InjectableApplication {
    private ObjectGraph objectGraph;

    @Override
    public void onCreate() {
        super.onCreate();

        objectGraph = ObjectGraph.create(new MyApplicationModule(this));
        objectGraph.inject(this);
    }

    @Override
    public void inject(Object o) {
        objectGraph.inject(o);
    }

    public ObjectGraph getObjectGraph() {
        return objectGraph;
    }
}

这是我的 AndroidManifest.xml ：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="app"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="18"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:name="app.MyApplication" >
        <activity
            android:name="app.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

我还将Dagger罐子包含在构建路径和工厂路径中。

Answer 1

对于任何可能像我一样遇到此问题的人。我面临的问题是我没有在我的gradle构建文件中添加依赖项，以允许匕首在我的类上进行代码生成：

添加：

apt 'com.squareup.dagger:dagger-compiler:1.2.2'

更新：如果您不知道apt插件的位置，可以将其安装在项目gradle文件中。我的依赖关系看起来像这样：

dependencies {
    classpath 'com.android.tools.build:gradle:1.0.0'
    classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4+'
}

Answer 2

我发现了我的错误：

您必须检查＆＃34; 启用项目特定设置＆＃34; for＆＃34; Java Compiler＆＃34;和＃34;注释处理＆＃34;。现在我的应用程序抛出了很多其他错误，但Dagger代码生成的东西可以工作！

Answer 3

如果您使用multiDex，请不要忘记将其激活到YourApp.class

   @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);

        MultiDex.install(this);
    }

这解决了我的类似问题。

project build.gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.5.0'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4+'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

app build.gradle：

buildscript {
    repositories {

        mavenCentral()
        ...
    }
...
}

...
apply plugin: 'com.android.application'
apply plugin: 'android-apt'
...
dependencies {
...
    compile 'com.squareup.dagger:dagger:1.2.2'
    provided 'com.squareup.dagger:dagger-compiler:1.2.2'
    apt 'com.squareup.dagger:dagger-compiler:1.2.2'
...


  }

   configurations {
      provided
   }
