我正在尝试使用远程 API连接到我的本地 App Engine 项目。
这是我的来源:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RemoteApiOptions options = new RemoteApiOptions()
.server("192.168.1.5", 8888)
.credentials("username", "password");
RemoteApiInstaller installer = new RemoteApiInstaller();
try {
installer.install(options);
DatastoreService ds = DatastoreServiceFactory.getDatastoreService();
} catch(Exception e){
System.err.println(e.toString());
}finally {
installer.uninstall();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
我正在从App Engine Java SDK导入 appengine-api.jar、appengine-remote-api.jar 和 appengine-tools-api.jar 。
我在 Eclipse 和 IntelliJ 中都收到以下编译错误:

相同的代码可作为非 Android Java 项目进行,只需进行少量更改。
