There is a command to start an activity based on intent: am start. Also to send a broadcast: am broadcast.
I think probably there should be a shell command to query a content provider, probably something like:
query content://com.myapp.authority/path --where 'column=?' --arg 1 --order 'column desc'
or similar.
Is there one?
There is a content command:
usage: adb shell content [subcommand] [options]
usage: adb shell content insert --uri <URI> [--user <USER_ID>] --bind <BINDING> [--bind <BINDING>...]
<URI> a content provider URI.
<BINDING> binds a typed value to a column and is formatted:
<COLUMN_NAME>:<TYPE>:<COLUMN_VALUE> where:
<TYPE> specifies data type such as:
b - boolean, s - string, i - integer, l - long, f - float, d - double
Note: Omit the value for passing an empty string, e.g column:s:
Example:
# Add "new_setting" secure setting with value "new_value".
adb shell content insert --uri content://settings/secure --bind name:s:new_setting --bind value:s:new_value
usage: adb shell content update --uri <URI> [--user <USER_ID>] [--where <WHERE>]
<WHERE> is a SQL style where clause in quotes (You have to escape single quotes - see example below).
Example:
# Change "new_setting" secure setting to "newer_value".
adb shell content update --uri content://settings/secure --bind value:s:newer_value --where "name='new_setting'"
usage: adb shell content delete --uri <URI> [--user <USER_ID>] --bind <BINDING> [--bind <BINDING>...] [--where <WHERE>]
Example:
# Remove "new_setting" secure setting.
adb shell content delete --uri content://settings/secure --where "name='new_setting'"
usage: adb shell content query --uri <URI> [--user <USER_ID>] [--projection <PROJECTION>] [--where <WHERE>] [--sort <SORT_ORDER>]
<PROJECTION> is a list of colon separated column names and is formatted:
<COLUMN_NAME>[:<COLUMN_NAME>...]
<SORT_ORDER> is the order in which rows in the result should be sorted.
Example:
# Select "name" and "value" columns from secure settings where "name" is equal to "new_setting" and sort the result by name in ascending order.
adb shell content query --uri content://settings/secure --projection name:value --where "name='new_setting'" --sort "name ASC"
usage: adb shell content call --uri <URI> --method <METHOD> [--arg <ARG>]
[--extra <BINDING> ...]
<METHOD> is the name of a provider-defined method
<ARG> is an optional string argument
<BINDING> is like --bind above, typed data of the form <KEY>:{b,s,i,l,f,d}:<VAL>
