android - 如何使用任何通知消息开始活动，例如“abc”

Question

当我收到通知消息“abc”时，我想打开我的应用程序。我可以用 SMSReceiver 做到这一点，但只能收到短信。我想做这个whatsapp消息。抱歉英语不好。

@Override
public void onReceive(Context context, Intent intent) {

    String hangiNumaradan = "";
    String neYazmis = "";

    Bundle bundle = intent.getExtras();
    SmsMessage[] msgs = null;


    if (bundle != null) {

        Object[] pdus = (Object[]) bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];
        for (int i = 0; i < msgs.length; i++) {
            msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
            hangiNumaradan += msgs[i].getOriginatingAddress();
            neYazmis += msgs[i].getMessageBody().toString();
        }


        Toast.makeText(context, hangiNumaradan + " gelen mesaj " + neYazmis, Toast.LENGTH_LONG).show();
    }

}

此代码是 smsreceiver 和 toast 消息。

在做了一些调查后，我意识到自从 Facebook 收购了 Whatsapp，他们关闭了所有公共的 Whatsapp API，现在不可能创建 Whatsapp 消息接收器，但是你可以做一件事。

1. 创建AccessibilityService：

   公共类 MyAccessibilityService 扩展 AccessibilityService {

   @Override
   public void onAccessibilityEvent(AccessibilityEvent event) {
       //here you can implement your reaction for incoming notification
       //here you can find some tags that could be helpful for you
       String helpful = event.getContentDescription();
   
       //In code below you could also retrieve some helpful info from Notification
       AccessibilityNodeInfo source = event.getSource();
           if (source == null) {
               return;
           }
   
           // Grab the parent of the view that fired the event.
           AccessibilityNodeInfo rowNode = getListItemNodeInfo(source);
           if (rowNode == null) {
               return;
           }
   
           // Using this parent, get references to both child nodes, the label and the checkbox.
           AccessibilityNodeInfo labelNode = rowNode.getChild(0);
           if (labelNode == null) {
               rowNode.recycle();
               return;
           }
   
           AccessibilityNodeInfo completeNode = rowNode.getChild(1);
           if (completeNode == null) {
               rowNode.recycle();
               return;
           }
   
           // Determine what the task is and whether or not it's complete, based on
           // the text inside the label, and the state of the check-box.
           if (rowNode.getChildCount() < 2 || !rowNode.getChild(1).isCheckable()) {
               rowNode.recycle();
               return;
           }
   
           CharSequence anotherInfoFromNotification = labelNode.getText();
   
   }
   
   @Override
   public void onInterrupt() {
   }
   

   }

2. 创建serviceconfig.xml文件：

   <accessibility-service android:accessibilityEventTypes="typeViewClicked|typeViewFocused" android:packageNames="com.whatsapp" android:accessibilityFeedbackType="feedbackSpoken" android:notificationTimeout="100" android:settingsActivity="com.example.android.your.way.to.activity" android:canRetrieveWindowContent="true"/>

3. 在清单中注册服务：

   <service android:name=".MyAccessibilityService"> <intent-filter> <action android:name="android.accessibilityservice.AccessibilityService" /> </intent-filter> <meta-data android:name="android.accessibilityservice" android:resource="@xml/serviceconfig" /> </service>

所以总结一下：您将能够监听所有传入的whatsapp消息，您必须尝试更多地使用onAccessibilityEvent方法中的代码来从消息中检索信息。
