[英]Start service from the same activity in android
I have a class which extend Intent service. 我有一个扩展Intent服务的类。 I want to start service from this activity but I get erroor:
我想从这个活动开始服务,但我得到了错误:
Intent msgIntent = new Intent();
msgIntent.setClass(testActivity, testActivity.class);
startService(msgIntent);
07-15 11:53:33.030: E/AndroidRuntime(28989): java.lang.NullPointerException
07-15 11:53:33.030: E/AndroidRuntime(28989): at android.content.ContextWrapper.getApplicationContext(ContextWrapper.java:109)
How can I start service from the same activity? 如何从同一活动开始服务?
Intent msgIntent = new Intent(YourClass.this, TestService.class);
startService(msgIntent);
it looks like you are calling startService with testActivity, which is an activity, not a service. 看起来你正在用testActivity调用startService,这是一个活动,而不是一个服务。
try like that: 试试这样:
Intent msgIntent = new Intent(this, yourIntentService.class);
startService(msgIntent);
