android - 使用 GCM 的 android 代码中的 getErrorCodeName() 出错

Question

如何纠正“MulticastResult 类型的方法 getErrorCodeName() 未定义”错误？我使用了以下代码

           MulticastResult result = sender.send(message, androidTargets, 1);

            if (result.getResults() != null) {
                int canonicalRegId = result.getCanonicalIds();
                if (canonicalRegId != 0) {
                    // same device has more than on registration ID: update database
                }
            } else {
                int error = result.getFailure();
                System.out.println("Broadcast failure: " + error);
                String error_code_name = result.getErrorCodeName(); //Error is Here
                if (error_code_name.equals(Constants.ERROR_NOT_REGISTERED)) {
                       // application has been removed from device - unregister database or remove from database
                     }
            }

提前致谢 ！

你想这样做：

 result.getResults().get(0).getErrorCodeName();

或类似的东西：

for(Result r : result.getResults()){ 
     if (Constants.ERROR_NOT_REGISTERED.equals(r)) {
           // application has been removed from device - unregister database or remove from database
     }   
}
