Android doesn't receive push notification from

问题:

When I am testing the Parse Push to my Android phones the push notification come through as long as the app runs. If the app is closed: I just get a message saying <App name> has stopped. - I don't receive any of the pushes - but still got the stop notification popup. I have followed the Quickstart guide from Parse step by step.

回答1:

Have the parse initialized in Application class similar as below

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();
    }
}

Don't forget to reference your app class in manifest

<application android:name=".AppClass">

Remove Parse init from MainActivity

Sorry - I don't know to use the right function for implement code to Stack - please say so if you have a better way.

I still got the "You must call Parse.initialize(context, applicationId, clientKey) before using the Parse library." error. Now i can't reccive notifications even when the app is open. I have splitted the Parse Push to another class. Under is my source code.

MainActivity

package org.ostsia.ostsia;

import android.app.Application;

    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

            }

            // 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;
            }

            }
