创建和QUOT;电池使用＆QUOT;意图安卓

问题描述：

在我的Nexus One，有来自设置>关于手机>电池使用一个方便的应用程序访问。

On my nexus one, there is a handy app reachable from Settings > About Phone > Battery use.

我想给startActivity（）从我的活动一个应用程序。

I'd like to StartActivity() that app from one of my Activities.

我的日志，当设置运行它，这个意图是记录在看

I can see in the log that when Settings runs it, this intent is logged:

Starting activity:
  Intent { act=android.intent.action.MAIN
           cmp=com.android.settings/.fuelgauge.PowerUsageSummary }

我在与麻烦的东西在Android的Java源代码。我甚至无法找到在GIT源fuelgauge。任何人都可以点我正确的文件，或其他任何有帮助的，比如如何建立正确的意向？

I'm having trouble relating that to something in Android Java source. I can't even find "fuelgauge" in the GIT source. Can anyone point me to the right file, or anything else helpful, like how to create the right kind of Intent?

感谢

答

code是如下：

Intent powerUsageIntent = new Intent(Intent.ACTION_POWER_USAGE_SUMMARY);
ResolveInfo resolveInfo = getPackageManager().resolveActivity(powerUsageIntent, 0);
// check that the Battery app exists on this device
if(resolveInfo != null){
    startActivity(powerUsageIntent);
}
