Google map 不能用~

这是在程序中的代码：
address_D.setOnClickListener ( new View.OnClickListener () {
@Override
public void onClick(View v) {

String location = address_D.getText ().toString ();
List<Address> addressList;

if (!location.equals ( "" )) {
Geocoder geocoder = new Geocoder ( DisplayActivity.this );

try {
addressList = geocoder.getFromLocationName ( location, 5 );
if (addressList != null) {
for (int i = 0; i < addressList.size (); i++) {
Intent intent = new Intent ( Intent.ACTION_VIEW );
intent.setData ( Uri.parse ( "geo:" + addressList.get ( i ).getLatitude () + "," + addressList.get ( i ).getLongitude () + "?q=" + location ) );

try {
startActivity ( intent );
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(DisplayActivity.this, "This sentence is for checking the error.",Toast.LENGTH_SHORT).show();
}

}
}
} catch (IOException e) {

e.printStackTrace ();
}
} else {

Toast.makeText ( DisplayActivity.this, "This person hasn't given the location yet!", Toast.LENGTH_SHORT ).show ();

}
}
} );

这是在点击该按钮出现提示的问题;
