He estado intentando probar un servicio cuando un dispositivo se inicia en Android, pero no puedo hacer que funcione. Estoy tratando de iniciarlo con este comando de CMD:

(en .. \ AppData \ Local \ Android \ sdk \ platform-tools)

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

o

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -c android.intent.category.HOME -n net.fstab.checkit_android/.MyReceiver

AndroidManifest.xml

    </application>

</manifest>

mi clase de receptor es esta:

public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    System.out.println("MyReceiver !!!!");
    Intent startServiceIntent = new Intent(context, MioServizio.class);

context.startService(startServiceIntent);
}
}

la respuesta a mi comando dos es esta:

Broadcasting: Intent { act=android.intent.action.BOOT_COMPLETED cat=[android.intent.category.HOME] cmp=net.fstab.checkit_android/.MyReceiver }
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.BOOT_COMPLETED from pid=3715, uid=2000

¿Por qué tengo este error "java.lang.SecurityException: Permiso denegado"?
