Magento如何在选择特定送货方式时删除付款选项(Magento how to remove payment option when a specific shipping method is selected)

 这里你在第一行和第四行中使用相同的依赖关系两次，从这里删除一个。 不要多次使用相同的依赖关系 
 
 dependencies {
        compile project(':react-native-smart-splash-screen')//here
        compile project(':react-native-rw-get-gallery-image')
        compile project(':react-native-mauron85-background-geolocation')
        compile project(':react-native-background-task')
        compile project(':react-native-keep-awake')
        compile project(':react-native-background-timer')
        compile project(':react-native-image-resizer')
        compile project(':react-native-fcm')
        compile 'com.google.firebase:firebase-core:10.0.1' //this decides your firebase SDK version
        compile project(':react-native-fetch-blob')
        compile fileTree(dir: "libs", include: ["*.jar"])
        compile "com.android.support:appcompat-v7:23.0.1"
        compile "com.facebook.react:react-native:+"  // From node_modules
        compile project(':react-native-smart-splashscreen')//here
        compile project(':react-native-fs')
        compile project(':react-native-file-opener')
        compile project(':react-native-camera')
    }
 
 它会解决你的问题。 

Here you are using same dependencies two times in 1st line and in 4th last line remove one from here. don't use same dependencies for multiple times
 
 dependencies {
        compile project(':react-native-smart-splash-screen')//here
        compile project(':react-native-rw-get-gallery-image')
        compile project(':react-native-mauron85-background-geolocation')
        compile project(':react-native-background-task')
        compile project(':react-native-keep-awake')
        compile project(':react-native-background-timer')
        compile project(':react-native-image-resizer')
        compile project(':react-native-fcm')
        compile 'com.google.firebase:firebase-core:10.0.1' //this decides your firebase SDK version
        compile project(':react-native-fetch-blob')
        compile fileTree(dir: "libs", include: ["*.jar"])
        compile "com.android.support:appcompat-v7:23.0.1"
        compile "com.facebook.react:react-native:+"  // From node_modules
        compile project(':react-native-smart-splashscreen')//here
        compile project(':react-native-fs')
        compile project(':react-native-file-opener')
        compile project(':react-native-camera')
    }
 
It will solve your problem.
