apache cordova应用程序在收到parse.com推送通知后崩溃

Question

我想在我的Cordova应用程序中添加parse.com推送通知服务.我已经阅读了parse.com快速入门指南,并将SDK文件放在了libs文件夹中.之后我将代码添加到主java文件和AndroidManifest.xml中.该应用程序正常工作.parse.com可以接收我的设备令牌,我可以向设备发送推送通知,但在两三次推送通知后,应用程序将崩溃.

catlog中的错误消息是:

05-07 02:08:25.185: E/com.parse.PushService(28735): The Parse push service cannot start because Parse.initialize has not yet been called. If you call Parse.initialize from an Activity's onCreate, that call should instead be in the Application.onCreate. Be sure your Application class is registered in your AndroidManifest.xml with the android:name property of your <application> tag.

我搜索过,似乎很多开发人员都有完全相同的问题.我在parse.com帮助论坛中找到了两个主题:https : //www.parse.com/questions/app-crashes-after-after-screen-unlock https://www.parse.com/questions/cannot- send-push-to-android-after-app-is-closed-until-screen-unlock and this one: Android App在收到推送并且app关闭时崩溃

但对于不懂java的人来说,解决方案并不清楚.如何更改我的AndroidManifest.xml和主java文件以使其正常工作.

提前致谢

Answer 1

Parse推送服务无法启动,因为尚未调用Parse.initialize.如果从Activity的onCreate调用Parse.initialize,则该调用应该在Application.onCreate中.确保您的Application类在AndroidManifest.xml中注册,并带有标记的android:name属性.

尝试分离Activity和Application,创建一个新的类文件,例如MainApplication.

PushApp.java:

public class PushApp extends CordovaActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.init();
        // Set by <content src="index.html" /> in config.xml
        super.loadUrl(Config.getStartUrl());
        //super.loadUrl("file:///android_asset/www/index.html");
    }
}

MainApplication.java:

public class MainApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Parse.initialize(this, "xJK9ZA0Dtsjd8RwoNUUsIHPXzMRbmcxXGWqiw", "19g9eUKjLjlUdogHEXStUABNcvy2rA6azb5mXy");
        PushService.setDefaultPushCallback(this, PushApp.class);
        ParseInstallation.getCurrentInstallation().saveInBackground();
    }
}

并改变:

<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:name="PushApp" android:theme="@android:style/Theme.Black.NoTitleBar">

至:

<activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/app_name" android:name="MainApplication" android:theme="@android:style/Theme.Black.NoTitleBar">

现在,当应用程序关闭/屏幕被锁定时,您还应该收到推送通知
