HackRF One and Portapack Installation with Mayhem

Since the PortaPack that I bought off eBay was only $66.45, what could I expect but bare bones and not even bolts to hold the corners down. See images.

Nevertheless, the purpose of this exercise is loading Mayhem not aesthetics.  I followed the instructions HackRF+PortaPack+Mayhem firmware instructions on YouTube.

Here is my experience that includes the Mayhem flash tool NOT recognizing the HackRF+PortaPack.

1.  I had to first find a USB / SD card adapter so that I could format a 16 GB card to Fat32 from my Windows PC. 

2. Leaving the USB / SD card plugged in to my PC,  I then downloaded the Mayhem fork from GitHub. Two folders: mayhem_v1.3.0_COPY_TO_SDCARD.7z, mayhem_v1.3.0_FIRMWARE.7z

 3. After using the PC to copy the files to the SD card, I plugged that card into the newly assembled HackRF+PortPack.

4. Then I attached the antenna and connected the HackRF+PortPack to my PC with a USB cable.

5. The BIG SNAP was that the Mayhem flash tool (flash_portapack_mayhem.bat)  did not recognize the HackRF+Portapack.

6. I resolved this, by uninstalling the USB driver from inside Windows Device Manager. See images.

7. After the uninstall, I UNPLUGGED and PLUGGED back in the HackRF+PortaPack.

8. Windows then recognized it again and so did the Mayhem flash tool.

9. All good now. See success image.

Bare bones set up on the cheap.

Android 10 - Adding Icons to Menu Items

They don't make it easy and previous methods like the following do not work.

<item android:id="@+id/action_settings2"    
   android:title="@string/action_settings2"
   android:icon=@drawable/your_image"/>

I had to add a menu type image through Android Studio (See screen shots) and use the following menu XML:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.s33me.hamsandwich.BaseMenu"
    android:layout_height="match_parent" android:layout_width="match_parent">
    <item
        android:id="@+id/action_more"
        android:title=""
        >
      <item android:id="@+id/item1"
          android:icon="@drawable/ic_action_search"
          app:showAsAction="always"
          android:title="Search"
          />

    <item android:id="@+id/item4"
        android:icon="@drawable/ic_action_mail"
        app:showAsAction="always"
        android:title="Export"
        />
    <item android:id="@+id/item2"
        android:icon="@drawable/ic_action_home"
        app:showAsAction="ifRoom"
        android:title="Home"/>
    <item android:id="@+id/item3"
        android:icon="@drawable/ic_action_exit"
        app:showAsAction="ifRoom"
        android:title="Exit"
         />
    </item>
</menu>

This looks like this (ugly and inconsistent):

While I removed nearly twenty five of my old apps from Google Play, I also added a few that are meaningful to my current technological station in life like Ham Sandwich.  https://play.google.com/store/apps/details?id=com.s33me.hamsandwich
