The not processed duration of message is handled, terminal is pre-stored or is pre-configured with the second duration threshold value, and the second duration threshold value is greater than first
Duration threshold value, the second duration threshold value indicate that the overtime duration of ANR occurs for message to be processed, such as: the super of ANR occurs for incoming event
When constantly a length of 10s, i.e. incoming event not processed duration is more than 10s, ANR is generated, in other words, the second duration threshold value is
10s。
Wherein, the size of the second duration threshold value is related with the type of message to be processed.Such as: the second duration of incoming event
Threshold value is 10s, and the second duration threshold value of broadcast message is 60s, and the second duration threshold value of the message for starting service is 20s.
Wherein, when terminal determines that the not processed duration of message to be processed is more than the second duration threshold value, S508 is executed；Terminal
When determining that the not processed duration of message to be processed is less than the second duration threshold value, S506 is executed.It should be understood that due to the second duration
Threshold value is greater than the first duration threshold value, when the not processed duration of message to be processed is greater than the first duration threshold value, when not processed
Length is likely larger than the second duration threshold value, it is also possible to be less than or equal to the second duration threshold value.Message to be processed is not processed in S505
Duration at the time of can detect message to be processed using in S501 as with reference to the moment.
S506, stop crawl systrace information at the second moment.
Wherein, detected in the second moment and the second duration threshold value and S501 it is related at the time of message to be processed, such as:
Two moment were t2, t2=t0+T1, and shown in Figure 6, t0 is at the time of detecting message to be processed, and t1 was the first moment, and t2 is
Second moment, T1 are the first duration threshold value, and T2 is the second duration threshold value, and t1=t0+T1, t2=t0+T2, T2 is greater than T1.
Wherein, terminal can notify systrace to stop crawl systrace at the second moment in such a way that system is called
Information, such as: terminal sends crawl expiry notification to systrace.
S507, the systrace information for being discarded in the first moment and the crawl of the second moment.
Wherein, since ANR does not occur for terminal, the treatment process of message to be processed is normally that terminal can empty
The spatial cache of systrace information is discarded in the systrace information grabbed during the first moment and the second moment.
