Question

我在Android移动应用中使用Liferay Screens，以及Liferay Android Mobile SDK。我已将LoginScreenlet放入我的活动中。它显示正确，但是当我单击“登录”按钮时，我收到此错误：

我在Genymotion模拟器，Android 4.1.1（16级）上尝试这个。

我的应用程序的gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'com.jakewharton.hugo'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.mimacom.lrhc"
        minSdkVersion 16
        targetSdkVersion 23

        versionName "1.0"
    }
    compileOptions {

        targetCompatibility "1.7"
    }
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/NOTICE'
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    productFlavors {
        mock {}
        prod {}
    }
}

    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'

    compile 'com.liferay.mobile:liferay-screens:1.3.0'
    compile 'com.liferay.mobile:liferay-material-viewset:1.3.0'
}

我找到了一篇关于类似问题的论坛帖子，但是对于旧版Liferay Screens来说也是如此。我猜1.3.0应该已经兼容了。 https://web.liferay.com/community/forums/-/message_boards/message/60438799

这确实是一个依赖性问题还是其他问题？

Answer 1

这是一个依赖性问题，6.2.0.22是旧版本，而屏幕1.3.0正在使用较新的版本，并且有更改API。

您不需要依赖移动SDK，您可以使用屏幕中嵌入的内容（更新https://github.com/liferay/liferay-screens/blob/develop/android/Migrate%20to%20Liferay%20Screens%201.2.md中文档中记录的一些代码后

Liferay Screens Android中的NoClassDefError com.liferay.mobile.screens.base.interactor.JSONObjectCallback
