Sharing files between Android mobile and wear modules

问题

Several months ago, I originally started my project with just a mobile module, and now I am interested in configuring my app for wearable devices as well. That said, all of my files (Java, XML, drawables, and etc.) are in the mobile module, so do I need to transfer all of the files I want to share between mobile and wear modules into a newly created "common" module?

EDIT:

Can somebody explain to me what the following Gradle project sync errors coming from the mobile and wear's Gradle files mean:

... This happened after I included compile project(':common') in both modules as follows:

First, here's my common module:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "dpark.gameoflife"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
}

Mobile module:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "dpark.gameoflife"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    wearApp project(':wear')
    compile project(':common')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.google.android.gms:play-services:8.4.0'
}

Lastly, my wear module:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "dpark.gameoflife"
        minSdkVersion 20
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.support:wearable:1.3.0'
    compile 'com.google.android.gms:play-services-wearable:8.4.0'
    compile project(':common')
}

... If anything, I signed an APK of my common module in release mode, and yet I get the same errors as shown above.

回答1:

Correct, If your files are used by both modules (mobile and wear) then obviously, you should make these two modules use a shared module where you put all the necessary files.

in each module add compile project(': common')

回答2:

As mentioned here:

1- Make sure the first line in the build.gradle (Module:my-library-module), is defined correctly as:

apply plugin: 'com.android.library'

2- Add the library to the settings.gradle as:

include ':app', ':my-library-module'

3- Compile the library in the build.gradle (Module:xxx)(Module:mobile) as:

dependencies {
    compile project(":my-library-module")
}

4- In your project, import the library as:

import xxx.xx.xx
