Question

我想显示当前位置。我可以在我的应用上显示Google地图，但当前位置不会显示。我向Manifest.xml添加了以下权限。

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>

实际上当我确认logcat时，onLocationChanged（）没有被调用。我不知道原因。我应该在哪里修理？请帮帮我。

~MyActivity~

试试这个..

您是否在清单上添加了

<permission
    android:name="pakagename.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

onLocationChanged（）没有被调用
