How to test Alarm Manager on Android?

Question

Java

Using a StackOverflow article , I did something similar for myself, including registering a signal at startup and a service.
The debugger did not enter either the Alarm class, or the Service class, or the BootStart class, even despite the waitForDebugger() line. After some torment, I added a direct call to the service at the start of the initial Activity and somehow still managed to call the service, where I registered signals that fire once a minute.
As a result, something like this appears:

02-06 21:55:47.894      101-116/system_process E/ActivityManager﹕ ANR in com.dracontis.Activities:remote
    Reason: Broadcast of Intent { flg=0x14 cmp=com.dracontis.Activities/com.dracontis.Services.DailyAlarm (has extras) }
    Load: 0.34 / 0.18 / 0.05

    8.6% 116/ActivityManager: 3.4% user + 5.1% kernel
    26% TOTAL: 0% user + 21% kernel + 5.2% softirq

I decided to ask the question anyway, but there could not be a reason that instead of:

<action android:name="android.intent.action.BOOT_COMPLETED"></action>

I use

<action android:name="android.intent.action.BOOT_COMPLETED"/>

Or is the reason something else?

Yes, in vain I thoughtlessly decided to copy the code. Still, an example is better:

After I adjusted it to the application, everything worked. There is an error somewhere on Stackoverflow, and it's easy to get confused in the code layouts.
