Answer 1

在应用程序标记下声明您的元标记： -

<application
    android:allowBackup="true"
    .................>

    <meta-data 
        android:name="com.google.android.gms.version"
       android:value="4452000" />

输入所需的整数或从整数文件中引用它

Answer 2

您必须在meta-data标记内添加一个application标记，如您提供的logcat所示

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

当我检查googleplayservices的可用性时，应用程序崩溃
