將Google Maps添加到Android App

Question

我和我的小組成員一直在嘗試在一項活動中添加Google地圖，但所有嘗試均失敗。 我們想尋求幫助。

我們遵循了這里的步驟。

AndroidManifest.xml

我相信您必須擁有步驟4中所述的android密鑰，然后替換

    android:name="com.google.android.maps.v2.API_KEY"
    android:value="intentionally left blank" />

與

    android:name="com.google.android.maps.v2.API_KEY"
    android:value="xxxxxxxxxxxxxxxxx" />
