adb shell调试contentprovider相关命令-千里马android framework_adb 模拟往contentprivider写数据-优快云博客

hi，经常在做android系统应用开发，或者framework时候其实都少不了和contentprovider打交道，这里contentprovider其实也算android四大组件中非常重要的一个组件。经常如果涉及到数据库操作和跨进程一些通信，如果我们需要测试contentprovider写的是否正确，可以被客户端调用正常主要有2种方法：
1、自己写一个demo来专门访问contentprovider方式，这种方式当然是ok的，但是每次需要访问contentprovider接口等都需要对代码进行修改，编译运行，其实效率相对比较低

2、使用adb shell相关的命令进行contentprovider的操作访问，这种方式其实是最为方便的，不需要写任何代码，只需要adb shell几个命令既可以搞定，但是奈何很多同学又不知道相关命令，所以这里对相关命令进行一个详细记录，也方便日后自己查询使用，
这里其实我们完全使用:adb shell content -h就可以看到所有操作细节及案例，非常详细：

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>

usage: adb shell content read --uri <URI> [--user <USER_ID>]
  Example:
  # cat default ringtone to a file, then pull to host
  adb shell 'content read --uri content://settings/system/ringtone > /mnt/sdcard/tmp.ogg' && adb pull /mnt/sdcard/tmp.ogg

usage: adb shell content gettype --uri <URI> [--user <USER_ID>]
  Example:
  # Show the mime-type of the URI
  adb shell content gettype --uri content://media/internal/audio/media/
