Description
What happened?
We see lot of strict mode violations on Appstart on Android devices
Following is to see in LogCAT
StrictMode policy violation; ~duration=558 ms: android.os.strictmode.DiskReadViolation
These times are really to long ... other entries have only times up to 20ms
Steps to reproduce?
Create an iOS App and launch
add
StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
.detectDiskReads()
.detectDiskWrites()
.detectAll()
.penaltyLog()
.build());
StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
.detectLeakedSqlLiteObjects()
.detectLeakedClosableObjects()
.penaltyLog()
.penaltyDeath()
.build());
super.onCreate(savedInstanceState);
to Mainactivity on createWhat did you expect to happen?
I expect to avoid these violations and decreasing accesstimes - because in my case location service can't start forgroundservices and an ANR is reported.
OneSignal Flutter SDK version
Release 5.3.2 and 5.30 tested
Which platform(s) are affected?
- iOS
- Android
