当应用关闭时，Android不会从Parse Push接收推送通知

Question

当我测试Parse Push到我的Android手机时，只要应用程序运行，推送通知就会通过。 如果应用程序已关闭：我只收到一条消息<App name> has stopped. - 我没有收到任何推送 - 但仍然会收到停止通知弹出窗口。我一步一步地遵循Parse的快速入门指南。

Answer 1

在Application类中初始化parse类似于下面的

public class AppClass extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        // Parse.enableLocalDatastore(this); // if you need this, put before init
        Parse.initialize(this, "gV6QK", "JJmFo99");
        PushService.setDefaultPushCallback(getApplicationContext(), MainActivity.class);
        ParseInstallation.getCurrentInstallation().saveInBackground();
    }
}

不要忘记在清单中引用您的应用类

<application android:name=".AppClass">

从MainActivity中删除Parse init

Answer 2

抱歉 - 我不知道使用正确的函数来实现堆栈的实现代码 - 如果你有更好的方法，请说明。

我仍然得到了＃34;你必须在使用Parse库之前调用Parse.initialize（context，applicationId，clientKey）。＆＃34;错误。现在，即使应用程序处于打开状态，我也无法接收通知。我把Parse Push分成了另一个类。下面是我的源代码。

MainActivity

＆＃13;

＆＃13;

package org.ostsia.ostsia;

import android.app.Activity;
import android.app.Application;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.content.Intent;
import android.net.Uri;


/*
 * Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but  that URL should open in the same screen.
 */

public class MainActivity extends Activity {
    /** Called when the activity is first created. */


    WebView web;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        web = (WebView) findViewById(R.id.webview01);
        web.setWebViewClient(new myWebClient());
        web.getSettings().setJavaScriptEnabled(true);
        web.loadUrl("http://tconsulting.no/ostsia");
    }



    public class myWebClient extends WebViewClient
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            // TODO Auto-generated method stub
            super.onPageStarted(view, url, favicon);
        }

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle it
            else if (url.startsWith("tel:")) {
                Intent tel = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
                startActivity(tel);
                return true;
            }
            else if (url.startsWith("mailto:")) {
                String body = "Enter your Question, Enquiry or Feedback below:\n\n";
                Intent mail = new Intent(Intent.ACTION_SEND);
                mail.setType("application/octet-stream");
                mail.putExtra(Intent.EXTRA_EMAIL, new String[]{"email address"});
                mail.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                mail.putExtra(Intent.EXTRA_TEXT, body);
                startActivity(mail);
                return true;
            }
            return true;
        }
    }

    // To handle "Back" key press event for WebView to go back to previous screen.
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
            web.goBack();
            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
}

＆＃13;

＆＃13;

AppClass

＆＃13;

＆＃13;

package org.ostsia.ostsia;


import android.app.Application;


import org.ostsia.ostsia.MainActivity;
import com.parse.Parse;
import com.parse.ParseInstallation;
import com.parse.ParsePush;

public class AppClass extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        Parse.initialize(this, "XXX", "XX");
        // Parse.setDefaultPushCallback(getApplicationContext(), MainActivity.java);
        ParseInstallation.getCurrentInstallation().saveInBackground();
    }

}
