As many already noticed  the problem manifests itself only if the extra string contains whitespaces   The root cause is that OP s host OS shell  i e  Windows cmd exe  mangles the entered command - the   characters get lost  --es sms body  test from adb  becomes --es sms body test from adb  Which results in sms body string extra getting assigned the value of test and the rest of the string becoming  lt URI gt   lt PACKAGE gt   lt COMPONENT gt  specifier   To avoid all that you could use   adb shell  am broadcast -a com whereismywifeserver intent TEST --es sms body  test from adb  -n com whereismywifeserver  IntentReceiver    or just start the interactive adb shell session first and run the am broadcast command from inside of it

I ve found that the command was wrong  correct command contains  broadcast  instead of  start    adb shell am broadcast -a com whereismywifeserver intent TEST --es sms body  test from adb  -n com whereismywifeserver  IntentReceiver

The true way to send a broadcast from ADB command  is    adb shell am broadcast -a com whereismywifeserver intent TEST --es sms body  test from adb    And  -a means ACTION  --es means to send a String extra      PS  There are other data type you can send by specifying different params like    -e --es  lt EXTRA KEY gt   lt EXTRA STRING VALUE gt        --esn  lt EXTRA KEY gt        --ez  lt EXTRA KEY gt   lt EXTRA BOOLEAN VALUE gt        --ei  lt EXTRA KEY gt   lt EXTRA INT VALUE gt        --el  lt EXTRA KEY gt   lt EXTRA LONG VALUE gt        --ef  lt EXTRA KEY gt   lt EXTRA FLOAT VALUE gt        --eu  lt EXTRA KEY gt   lt EXTRA URI VALUE gt        --ecn  lt EXTRA KEY gt   lt EXTRA COMPONENT NAME VALUE gt    --eia  lt EXTRA KEY gt   lt EXTRA INT VALUE gt    lt EXTRA INT VALUE           mutiple extras passed as Integer     --eial  lt EXTRA KEY gt   lt EXTRA INT VALUE gt    lt EXTRA INT VALUE           mutiple extras passed as List lt Integer gt    --ela  lt EXTRA KEY gt   lt EXTRA LONG VALUE gt    lt EXTRA LONG VALUE           mutiple extras passed as Long     --elal  lt EXTRA KEY gt   lt EXTRA LONG VALUE gt    lt EXTRA LONG VALUE           mutiple extras passed as List lt Long gt    --efa  lt EXTRA KEY gt   lt EXTRA FLOAT VALUE gt    lt EXTRA FLOAT VALUE           mutiple extras passed as Float     --efal  lt EXTRA KEY gt   lt EXTRA FLOAT VALUE gt    lt EXTRA FLOAT VALUE           mutiple extras passed as List lt Float gt    --esa  lt EXTRA KEY gt   lt EXTRA STRING VALUE gt    lt EXTRA STRING VALUE           mutiple extras passed as String    to embed a comma into a string       escape it using        --esal  lt EXTRA KEY gt   lt EXTRA STRING VALUE gt    lt EXTRA STRING VALUE           mutiple extras passed as List lt String gt   to embed a comma into a string       escape it using        -f  lt FLAG gt     For example  you can send an int value by   --ei int key 0

You need not specify receiver  You can use adb instead   adb shell am broadcast -a com whereismywifeserver intent TEST  --es sms body  test from adb    For more arguments such as integer extras  see the documentation

I am not sure whether anyone faced issues with getting the whole string  test from adb   Using the escape character in front of the space worked for me   adb shell am broadcast -a com whereismywifeserver intent TEST --es sms body  test  from  adb  -n com whereismywifeserver  IntentReceiver

Another thing to keep in mind  Android 8 limits the receivers that can be registered via manifest  e g   statically   https   developer android com guide components broadcast-exceptions

I had the same problem and found out that you have to escape spaces in the extra   adb shell am broadcast -a com whereismywifeserver intent TEST --es sms body  test  from  adb    So instead of  test from adb  it should be   test  from  adb
