Application manifests

一些平台上需要提供 manifests 片段 (或称存根) 来为扩展提供支持. 可以是部分 AndroidManifest.xml, Info.plist 或者 engine_template.html

从应用基础 manifest 开始, 每个扩展 manifest 存根一个一个的被应用. 基础 manifest 可以是默认的 (位于 builtins\manifests\<platforms>\...), 也可以是由用户自定义的.

命名和结构

扩展 manifests 必须被放置在适当的指定位置才能生效.

/myextension
    ext.manifest
    /manifests
        /android
            AndroidManifest.xml
        /ios
            Info.plist
        /osx
            Info.plist
        /web
            engine_template.html

Android

Android 平台提供了 manifest 混合工具 (基于 ManifestMerger2), bob.jar 中使用此工具混合 Manifest. 关于 Android manifests 的详细信息, 参见 官方文档

如果扩展 manifest 中没有设置应用的 android:targetSdkVersion , 下列权限会被自动加入: WRITE_EXTERNAL_STORAGE, READ_PHONE_STATE, READ_EXTERNAL_STORAGE. 详情请见 此文档. 我们推荐这么设置: <uses-sdk android:targetSdkVersion=“{{android.target_sdk_version}}” />

示例

基础 manifest

    <?xml version='1.0' encoding='utf-8'?>
    <manifest xmlns:android='http://schemas.android.com/apk/res/android'
            package='com.defold.testmerge'
            android:versionCode='14'
            android:versionName='1.0'
            android:installLocation='auto'>
        <uses-feature android:required='true' android:glEsVersion='0x00020000' />
        <uses-sdk android:minSdkVersion='9' android:targetSdkVersion='26' />
        <application android:label='Test Project' android:hasCode='true'>
        </application>
        <uses-permission android:name='android.permission.VIBRATE' />
    </manifest>

扩展 manifest:

    <?xml version='1.0' encoding='utf-8'?>
    <manifest xmlns:android='http://schemas.android.com/apk/res/android' package='com.defold.testmerge'>
         <uses-sdk android:targetSdkVersion=“{{android.target_sdk_version}}” />
        <uses-feature android:required='true' android:glEsVersion='0x00030000' />
        <application>
            <meta-data android:name='com.facebook.sdk.ApplicationName'
                android:value='Test Project' />
            <activity android:name='com.facebook.FacebookActivity'
              android:theme='@android:style/Theme.Translucent.NoTitleBar'
              android:configChanges='keyboard|keyboardHidden|screenLayout|screenSize|orientation'
              android:label='Test Project' />
        </application>
    </manifest>

混合结果

    <?xml version='1.0' encoding='utf-8'?>
    <manifest xmlns:android='http://schemas.android.com/apk/res/android'
        package='com.defold.testmerge'
        android:installLocation='auto'
        android:versionCode='14'
        android:versionName='1.0' >
        <uses-sdk
            android:minSdkVersion='9'
            android:targetSdkVersion='26' />
        <uses-permission android:name='android.permission.VIBRATE' />
        <uses-feature
            android:glEsVersion='0x00030000'
            android:required='true' />
        <application
            android:hasCode='true'
            android:label='Test Project' >
            <meta-data
                android:name='com.facebook.sdk.ApplicationName'
                android:value='Test Project' />
            <activity
                android:name='com.facebook.FacebookActivity'
                android:configChanges='keyboard|keyboardHidden|screenLayout|screenSize|orientation'
                android:label='Test Project'
                android:theme='@android:style/Theme.Translucent.NoTitleBar' />
        </application>
    </manifest>

iOS / macOS

对于 Info.plist 我们实现了专用的工具混合列表和字典. 可以在键上指定混合属性 merge, keep 或 replace, 默认是 merge.

HTML5

对于 html 模板, 我们给各部分命名, 以便混合时相匹配 (比如 “engine-start”). 标签属性可以是 merge 或者 keep. merge 是默认值.

示例

基础 manifest

    <!DOCTYPE html>
    <html>
    <body>
     <script id='engine-loader' type='text/javascript' src='dmloader.js'></script>
     <script id='engine-setup' type='text/javascript'>
     function load_engine() {
         var engineJS = document.createElement('script');
         engineJS.type = 'text/javascript';
         engineJS.src = '{{exe-name}}_wasm.js';
         document.head.appendChild(engineJS);
     }
     </script>
     <script id='engine-start' type='text/javascript'>
         load_engine();
     </script>
    </body>
    </html>

扩展 manifest

         my_load_engine();
