     83 Read args from a config file:
     84 - allows use of more interesting args w/o risk of checking them in by mistake
     85 - allows use of different args w/o rebuilding the app
     86 - uses compiled in defaults if config file missing or broken
     87 
     88 Example android-config.json:
     89 ```
     90 {
     91   "args": [
     92     "--npub",
     93     "npub1h50pnxqw9jg7dhr906fvy4mze2yzawf895jhnc3p7qmljdugm6gsrurqev",
     94     "-c",
     95     "contacts",
     96     "-c",
     97     "notifications"
     98   ]
     99 }
    100 ```
    101 
    102 Install/update android-config.json with:
    103 ```
    104 adb push android-config.json /sdcard/Android/data/com.damus.app/files/android-config.json
    105 ```
    106 
    107 Using internal storage would be better but it seems hard to get the config file onto
    108 the device ...
