Android接入Facebook登录踩坑记录

官方文档：https://developers.facebook.com/docs/facebook-login/android

Facebook SDK

Facebook SDK包含

• facebook-core
• facebook-common
• facebook-login
• facebook-share
• facebook-places
• facebook-applinks
• facebook-marketing
• facebook-messenger
• notifications
• AccountKit

实现登录功能至少需要

• facebook-core
• facebook-common
• facebook-login

可以分别引入core、common、login，也可以直接引入facebook-android-sdk

Atlas Bundle中引用Facebook SDK

如使用Atlas远程Bundle形式加载，则AndroidManifest.xml中的facebook_app_id和fb_login_protocol_scheme不能包含Bundle内部的string等资源，否则导致AndroidManifest.xml会被merge到host中，但string.xml不会，从而找不到资源

app\build\intermediates\manifests\full\debug\AndroidManifest.xml:73: error: Error: No resource found that matches the given name (at 'value' with value '@string/facebook_app_id').

app\build\intermediates\manifests\full\debug\AndroidManifest.xml:74: error: Error: No resource found that matches the given name (at 'theme' with value '@style/com_facebook_activity_theme').

app\build\intermediates\manifests\full\debug\AndroidManifest.xml:82: error: Error: No resource found that matches the given name (at 'scheme' with value '@string/fb_login_protocol_scheme').

value和scheme

若在AndroidManifest.xml中直接将value和scheme用facebook_app_id和fb_login_protocol_scheme的值写死

App Ids cannot be directly placed in the manifest.They must be prefixed by 'fb' or be placed in the string resource file.

解决方案：将facebook_app_id和fb_login_protocol_scheme放在公共module的资源文件中，然后在AndroidManifest.xml中引用

<string name="facebook_app_id">2147844112xxxxxx</string>
<string name="fb_login_protocol_scheme">fb2147844112xxxxxx</string>

theme

FacebookActivity需要指定公共的Theme，给FacebookActivity更换Theme可能会出现冲突，可以通过给Activity添加tools:replace="android:theme"解决。

<activity android:name="com.facebook.FacebookActivity"
    android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
    android:label="@string/app_name"
    tools:replace="android:theme"
    android:theme="@android:style/Theme.Translucent.NoTitleBar"
    />

CardView资源找不到

Facebook SDK内置CardView，若外部再次引用会报版本冲突或找不到资源

app\build\intermediates\awb-res\merged\debug\me.yezhou.lib-social\layout\com_facebook_device_auth_dialog_fragment.xml:22: error: No resource identifier found for attribute 'cardElevation' in package 'me.yezhou.lib.social'
No resource identifier found for attribute 'cardBackgroundColor' in package 'me.yezhou.lib.social'

zxing依赖冲突

facebook-android-sdk包含com.google.zxing.core二维码扫描依赖，如公共module或其他bundle也依赖zxing，注意冲突

Gradle依赖

dependencies {
//    compile('com.facebook.android:facebook-core:4.36.1', {
//        exclude group: 'com.android.support'
//    })
//    compile('com.facebook.android:facebook-common:4.36.1', {
//        exclude group: 'com.android.support'
//    })
//    compile('com.facebook.android:facebook-login:4.36.1', {
//        exclude group: 'com.android.support'
//    })
    compile('com.facebook.android:facebook-android-sdk:4.36.1', {
        //exclude group: 'com.android.support'
        exclude group: 'com.android.support', module: 'appcompat'
        exclude group: 'com.google.zxing'
    })
}
