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，推送通知效果很好。但是，如果应用程序没有运行，它总是会崩溃。我使用了 logcat，它说如下：

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

如何修复此 NullPointerException？

其实这是一个bug。

您可以通过创建单独的应用程序类来解决此问题。

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);
    }
}
