當Facebook應用程序安裝時,我的Facebook登錄按鈕可以正常工作。未安裝Facebook應用程序時,facebook登錄按鈕點擊失敗

當設備上沒有安裝Facebook應用程序,它崩潰我的應用程序:

清單:

<activity 
    android:name="com.facebook.CustomTabActivity" 
    android:exported="true"> 
    <intent-filter> 
     <action android:name="android.intent.action.VIEW" /> 
     <category android:name="android.intent.category.DEFAULT" /> 
     <category android:name="android.intent.category.BROWSABLE" /> 
     <data android:scheme="@string/fb_login_protocol_scheme" /> 
    </intent-filter> 
</activity> 

而fb_login_protocol_scheme值以 「FB」 開始需要。

搖籃依賴性:

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    compile 'com.android.support:appcompat-v7:25.3.0' 
    compile 'com.android.support:design:25.3.0' 
    compile 'com.google.firebase:firebase-core:10.2.1' 
    compile 'com.google.firebase:firebase-database:10.2.1' 
    compile 'com.google.firebase:firebase-ads:10.2.1' 
    compile ('com.facebook.android:facebook-android-sdk:4.20.0') // app invites 
    { 
     exclude group: 'com.android.support' 
    } 
    compile 'com.facebook.android:audience-network-sdk:4.20.0' 
    compile "com.android.support:cardview-v7:25.3.0" 
    testCompile 'junit:junit:4.12' 
} 

我怎樣才能解決呢?

我想你應該檢查一下,是否安裝了facebook。 看看這個答案:

但是Facebook在他們的教程中寫道:「當您啓用Chrome自定義選項卡時,當未安裝Facebook應用程序時,SDK會在Chrome自定義選項卡中顯示登錄對話框,而不是WebView。」 –

您是從Facebook的依賴排除 'com.android.support'。我認爲這是因爲它沒有包含與您相同版本的支持庫(facebook sdk 4.20.0使用android:support:25.0.0,但包含支持庫25.3.0,因此排除它是正確的做)。

但是,如果你想擁有CustomTab功能的工作,你因此必須在應用程式的依賴相應的依賴,所以添加以下行:

compile 'com.android.support:customtabs:25.3.0' 

,它應該工作。
