Can't find Android Activity from ADB

Here is a partial list of an AndroidManifest.xml of interest. This declares an Activity of SendCoinsActivity class in de.schildbach.wallet.ui.send package. Using ADB(Android Debug Bridge), I tried to launch this activity by

• adb shell am start -n de.schildbach.wallet.ui.send/.SendCoinsActivity -a android.intent.action.VIEW
• or by something similar to this by changing action and category options.

But I met the following error

Error type 3 Error: Activity class{de.schildbach.wallet.ui.send/de.schildbach.wallet.ui.send.SendCoinsActivity} does not exists.

I do not understand why.
