这里的行以前用于启动地图和它的工作fine.Later我发现谷歌doen't使用LocationClient再和他们使用GoogleAPIClient instead.So我改成了我的onCreate（）Method..The 2评论。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button send = (Button) findViewById(R.id.button2);
if(initMap())
{
//mLocationClient = new LocationClient(this,this,this);
//mLocationClient.connect();
mGoogleApiClient =new GoogleApiClient.Builder(MainActivity.this)
.addApi(LocationServices.API)
.addConnectionCallbacks(MainActivity.this)
.addOnConnectionFailedListener(MainActivity.this)
.build();
}
else
{
Toast.makeText(this,"Map Not Available!",Toast.LENGTH_SHORT).show();
}
}
这是initMap方法
private boolean initMap(){
if(mMap==null)
{
//making Reference to Map Object
SupportMapFragment mapFrag = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
mMap=mapFrag.getMap();
}
return(mMap!=null);
}
这是logcat的报告。
