本文介绍了应用程序崩溃的服务启动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试从活动启动一个服务，但是当点击按钮调用它的模拟器停止我的应用程序，并告诉我说：应用程序（...）已意外停止，请重试。
im trying to start a service from an activity, but when the button click calls it the simulator stops my application and tells me: "the application (...) has stopped unexpectedly. please try again"
在我的表现，我有
＆LT;服务机器人：名称=机器人：启用=真正的机器人MainService。标签=主服务＆GT;＆LT; /服务＆GT;
的codeI用于调用服务（从TimerGuardActivity）
意向书我=新的意图（TimerGuardActivity.this，MainService.class）;
i.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
TimerGuardActivity.this.startService（我）;
Intent i = new Intent(TimerGuardActivity.this, MainService.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
TimerGuardActivity.this.startService(i);
整个服务本身
