java - Realm android, RealmTransformer 好像没有应用

Question

我是新手。

我使用:

• 安卓工作室 2.2.3
• 等级:2.14.1
• Realm 插件:“类路径”io.realm:realm-gradle-plugin:2.2.1“”

但是当我调用 Realm.init(context) 时它抛出异常；在我的 Activity 的 onCreate 中。

我的类(class):

import io.realm.Realm;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);


       Realm.init(this); //crashing line
   }
}

Build.gradle 模块级别:

apply plugin: 'com.android.application'
apply plugin: 'realm-android'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "*.demo"
        minSdkVersion 10
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner     "android.support.test.runner.AndroidJUnitRunner"
        jackOptions {
            enabled true
        }
        // Enabling multidex support.
        multiDexEnabled true
   }
   buildTypes {
       release {
          minifyEnabled false
          //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
  }

  compileOptions {
       targetCompatibility 1.8
       sourceCompatibility 1.8
   }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
   })
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support:design:25.1.0'
    compile 'com.android.support:multidex:1.0.1'

    compile 'com.github.pwittchen:reactivenetwork:0.7.0'
    testCompile 'junit:junit:4.12'
}

在此先感谢您的帮助。

Jack 不使用 Gradle 中的转换 API。

因此，依赖于 Transform API 的 Realm-Transformer 无法与 Jack 一起使用。

使用 Retrolambda 而不是 Jack 来支持 Java 8 功能。
