安卓-如果应用程序未运行，则推送NullpointerException

Question

我刚刚在我的项目中实现了Pushbots库。如果我的应用程序正在运行，推送通知就会工作得很好。但是，如果应用程序没有运行，它总是会崩溃。我使用了logcat，它显示如下：

 09-26 02:40:28.143: E/AndroidRuntime(18464): FATAL EXCEPTION:

如何修复此NullPointerException？

Answer 1

实际上，这是一个bug。

您可以通过创建单独的Application类来修复此问题。

package com.pusbots.androidpushbot;
import android.app.Application;
import com.pushbots.push.Pushbots;
public class SampleApplication extends Application {
private static final String SENDER_ID ="YOUR_SENDER_ID";
private static final String PUSHBOTS_APPLICATION_ID ="PUSHBOT_APP_ID";
    @Override 
   public void onCreate(){
        super.onCreate();
        Pushbots.init(this, SENDER_ID, PUSHBOTS_APPLICATION_ID);
    }
}
