我已經爲第二版創建了一個Google API密鑰,並在清單中使用了它,但我無法在設備上顯示地圖。我爲V2創建了Android Map API密鑰,無法顯示地圖
我遵循谷歌地圖文檔中提供的一切。我也用this link。

package com.example.googlenewmap;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
map = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
if (map != null) {
map.addMarker(new MarkerOptions().position(HAMBURG)
.title("Hamburg"));
map.addMarker(new MarkerOptions()
.position(KIEL)
.title("Kiel")
.snippet("Kiel")
.icon(BitmapDescriptorFactory
.fromResource(R.drawable.ic_launcher)));
}
}

什麼是你的佈局XML文件的樣子?你得到的錯誤是什麼? – Sean
無需擴展'FragmentActivity'擴展標準'Activity'。不需要使用'SupportMapFragment'。使用'MapFragment'。因爲你的minsdk是14而不是11並且低於 – Raghunandan
@Raghunandan謝謝你的回覆,但我已經使用過了,但那不起作用 – Michel
