在manifest 中不能粗心的这样写啊

需要再建一个application类 extends GDApplication

override various methods in order to style your application

1 public class MyApplication extends GDApplication{ 2 @Override 3 public Class<?> getHomeActivityClass() { 4 return MainActivity.class; 5 } 6 7 @Override 8 public Intent getMainApplicationIntent() { 9 return new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.app_url))); 10 } 11 12 }

android:name=".MyApplication">
