A application startup time is very long！！

wanshaowu — Mon, 07 May 2018 04:35:28 GMT

The application (see Appendix procedure)startup time is very long(about 18 seconds) at imx6Q android4.4.2 .

And the boot time is normal(about 4 seconds) in other versions of Android system, such as android4.2.2,android5.1 and android6.0.

So we think this application is related to imx6q android4.4.2 Kikt.

Here is a logcat fragment that starts the application under android4.4.2：

Please note that:

05-03 11:01:28.120 W/FlurryAgent( 3196): Flurry session started for context:com.mm.android.direct.gdmsspad.SplashActivity@41b310b8

05-03 11:01:43.430 I/ActivityManager( 2794): START u0 {cmp=com.mm.android.direct.gdmsspad/.MainActivity} from pid 3196

In other versions of the system will not happen such as "Launch timeout has expired, giving up wake lock! " and "Starting window AppWindowToken"

The 'com.mm.android.direct.gdmsspad.SplashActivity" ，It takes too much time to start！！

But the application can not be modified, and the system can only be modified

So please help me!

TKS!
