Answer 1

在您貼出LogCat，其明確表示，

You must have the following declaration within the <application> element:  <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

可能是你原諒請勿將Google Play服務版本添加到您的應用的Manifest。現在，在您Manifest內<application>元素添加此聲明...

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

Answer 2

在onResume()，您撥打：

map.moveCamera(CameraUpdateFactory.newLatLngBounds(latlngBounds, width, height, 150)); 

它有時可能返回null。

2.對於

..:E/AndroidRuntime(11838): Caused by: android.view.InflateException:Binary XML file... 

在onCreate()，

setContentView(R.layout.activity_navigation); 

而且

map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap(); 

的fragment與idmap - 應該在你layoutactivity_navigation - 區分大小寫。

<fragment 
android:id="@+id/map" 
class="com.google.android.gms.maps.SupportMapFragment" 
other layout properties /> 

Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml 

的meta標籤在你manifest有關googleplayservices版本，聲明不正確：爲
同樣要申報。預期的版本是4132500，但似乎宣佈爲0
檢查：
http://developer.android.com/guide/topics/manifest/meta-data-element.html

檢查主題，添加谷歌Play服務版本，您的應用程序的清單@

https://developers.google.com/maps/documentation/android/start

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