Android IBM Mobilefirst 7.1 PushNotifications:无法从后台检索到前台的通知文本

我们在MobileFirst应用程序中集成了基于标签的通知和广播通知。我们可以在应用程序打开并且用户能够看到通知文本时发送通知。但是，当用户杀死应用程序，通知到达通知面板时：用户可以单击通知并打开应用程序，但不会显示通知文本

请查找以下代码：

/* TagBased and Broadcast Notification Code Start */
var chkHolder;
function suborunsub(chkbxFlag){
console.log('The value of checkbox flag is:'+chkbxFlag);
var checkBox;
if(chkbxFlag=='TG1') {
    chkHolder = "TAG1";
    checkBox = document.getElementById("SUBTG1").checked;
    console.log('The checkbox value is:'+checkBox);
    if(checkBox) {
        subscribeToNotifTag('TAG1');
    } else {
        unsubscribeFromNotifTag('TAG1');
    }
} else if(chkbxFlag=='TG2') {
    chkHolder = "TAG 2";
    checkBox = document.getElementById("SUBTG2").checked;
    console.log('The checkbox value is:'+checkBox);
    if(checkBox) {

        subscribeToNotifTag('TAG2');
    } else {
        unsubscribeFromNotifTag('TAG2');
    }
} 
//---------------------------- Check if push support is available-----------
function isPushSupported() {
var isSupported = false;
if (WL.Client.Push){
    isSupported = WL.Client.Push.isPushSupported();
}   
WL.SimpleDialog.show("Alert", JSON.stringify(isSupported), [ {
    text : 'Close',
    handler : function() {}
  }
]);
}
// --------------------------------- Subscribe to tag --------------------

function subscribeToNotifTag(nTag) {
  WL.Client.Push.subscribeTag(nTag, {
        onSuccess: subscribeTagSuccess,
        onFailure: subscribeTagFailure
    });
}

function subscribeTagSuccess() {
    WL.SimpleDialog.show("Alert", "Subscribed to : "+chkHolder, [ {
    text : 'Close',
    handler : function() {}
  }
  ]);
}

function subscribeTagFailure() {
WL.SimpleDialog.show("Alert", "Failed to subscribe : "+chkHolder, [ {
    text : 'Close',
    handler : function() {}
  }
  ]);
}

// ------------------------------- Unsubscribe from tag --------------------

function unsubscribeFromNotifTag(nTag) {
WL.Client.Push.unsubscribeTag(nTag, {
        onSuccess: unsubscribeTagSuccess,
        onFailure: unsubscribeTagFailure
    });
}
function unsubscribeTagSuccess() {
WL.SimpleDialog.show("Alert", "Unsubscribed to : "+chkHolder, [ {
    text : 'Close',
    handler : function() {}
  }
  ]);
}

function unsubscribeTagFailure() {
WL.SimpleDialog.show("Alert", "Failed to unsubscribe : "+chkHolder, [ {
    text : 'Close',
    handler : function() {}
  }
  ]);
}

//------------------------------- Handle received notification -----------
WL.Client.Push.onMessage = function (props) {
if(WL.StaticAppProps.ENVIRONMENT=='iphone') {
WL.SimpleDialog.show("Alert", ""  + JSON.stringify(props.alert.body), [ {
    text : 'Close',
    handler : function() {}
}]);
}else if(WL.StaticAppProps.ENVIRONMENT=='android') {
    WL.SimpleDialog.show("Alert", ""  + JSON.stringify(props.alert), [ {
        text : 'Close',
        handler : function() {}
    }]);
    }
};

我尝试过使用示例应用程序附带的默认代码，效果很好。但是使用这个“WL.StaticAppProps.ENVIRONMENT”的原因是我们只想向用户显示通知文本。有没有最好的方法只向用户显示通知文本

“只是通知文本”是什么意思？这与默认通知有何不同？示例应用程序显示了如何访问通知对象并显示有效负载和道具。分别地

function pushNotificationReceived(props, payload) {

    WL.SimpleDialog.show("Push Notifications", "Provider notification data: " + JSON.stringify(props), [ {
        text : 'Close',
        handler : function() {
            WL.SimpleDialog.show("Push Notifications", "Application notification data: " + JSON.stringify(payload), [ {
                text : 'Close',
                handler : function() {}
              }]);      
        }
    }]);
}

无论应用是关闭还是打开，都会到达main.js文件中的相同代码路径；因此，问题是设置问题。可能在AndroidManifest.xml中-您可以添加它吗？你有什么改变吗？串？名称？应用程序已关闭，并且我们尚未更改清单文件中的任何字符串或名称。请说明您的确切版本号。您是否检查了示例应用程序？它也不工作吗？版本号：7.1.0.0-MFPF-IF201512191535。我已经在示例应用程序上试用过，效果很好。就连我也比较了两个android manifest.xml文件，除了一些额外的活动之外没有区别。删除代码中的“WL.StaticAppProps.ENVIRONMENT”条件检查，然后重试。当我们使用“+JSON.stringify（props）”时，它会将通知作为“提供者通知数据：{“警报”：测试，“徽章”：1，“声音”：null，“优先级”“：0}”。因此，在本文中，我们只想向用户显示“警报”：test。因此，我们将其自定义为“+JSON.stringify（props.alert）”。
