判斷應用程式是否在雙螢幕裝置上執行

使用此程式碼來判斷您的應用程式是否在 Surface Duo 雙螢幕裝置上執行。 您應該先執行這項檢查，然後再從與 Surface Duo 裝置互動的 Surface Duo SDK 呼叫 API。

Kotlin

fun isDeviceSurfaceDuo(): Boolean {
    val feature = "com.microsoft.device.display.displaymask"
    val pm = this.packageManager

    return if (pm.hasSystemFeature(feature)) {
        Log.i(TAG, "System has feature: $feature")
        true
    } else {
        Log.w(TAG, "System missing feature: $feature")
        false
    }
}

Java

private boolean isDeviceSurfaceDuo(){
    String feature = "com.microsoft.device.display.displaymask";
    PackageManager pm = this.getPackageManager();

    if (pm.hasSystemFeature(feature)) {
        Log.i(TAG, "System has feature: " + feature);
        return true;
    } else {
        Log.w(TAG, "System missing feature: " + feature);
        return false;
    }
}

警告

您可以查詢裝置名稱，但這不是未來無憂的硬式編碼值；我們不建議您這麼做。
