With there is no the progress information of " " in process title.For example：The entitled com.android.systemui of process
Progress information meet the requirements, retain；Process is entitled/the process letter of system/bin/su or zygote
Breath is not inconsistent requirement, excludes.
(3) if the process user of the first progress information (i.e.：User it is not) system nor with
The user of one preset characters string beginning, and in the process title of the first progress information comprising the first preset characters but
Not comprising the second preset characters, then retain first progress information；Wherein, the first progress information is output
Any progress information in whole progress informations in result, the first preset characters string be " u0_ " or " u1_ ",
Or " app_ ", the first preset characters are " ", and the second preset characters are "/".If that is, process is believed
User in breath be other situations (for example：Root, nfc etc.), then exclude in process name containing "/" but
There is no the progress information of " ".For example：The progress information of the entitled com.android.phone of process meets
It is required that, retain；The progress information of the entitled radio of process is not inconsistent requirement, excludes.
