android – Service.startForeground()在使用ServiceTestCase运行时抛出NullPointerException

This是一个已知的令人烦恼的2岁Android漏洞.

我的问题是除了修改Android源代码并再次编译之外,有没有人知道这个问题的解决方法？

这是我的代码,为了完成：

提升NPE的My service子类方法：

/** Shows notification of started service */
private void doStartForeground() {

    // Prepare notification
    final NotificationHelper nh = doNotification("service started");

    // Start foreground
    startForeground(nh.getNotificationId(),nh.getNotification());
}

这是从onCreate()方法覆盖调用的.

和JUnit测试方法：

public void test1() throws InterruptedException {
    assertTrue(context != @R_673_6633@
    final Intent service = new Intent();
    service.setComponent(new ComponentName(Coreservice.PACKAGE_NAME,Coreservice.serviCE_FULL_Name));
    IBinder binder = bindservice(servicE);
    assertTrue(binder != @R_673_6633@
}

堆栈跟踪：

java.lang.NullPointerException
at android.app.service.startForeground(service.java:631)
at com.blablabla.android.core.Coreservice.doStartForeground(Coreservice.java:82)

服务启动正常,并且在不通过Android的JUnit运行时工作正常.

/** JUNIT - this is for tesTing purposes only */
public static Boolean isJUnit = false;

// Start the service as foreground (Android should not kill this
// servicE)
if (!isJUnit) {
    doStartForeground();
}

@Override
protected void setUp() throws Exception {
    super.setUp();
    // More setup
    MyserviceClass.isJUnit = true;
}
