Hi,

We write an application to do ANT+ Heart Rate connection stress test.

We use MultiDeviceSearch API to search device, sometimes that will cause SQLite error.

How can to resolve this issue?

Thanks,

Hi all,

OS: Android L
ANT+ Plugins Service: 3.5.0

i monitor com.dsi.ant.plusings.antplus process:

$ adb shell ls -a /proc/"process's pid"/fd

When my android use MultiDeivceSearch to search HeartRate sensor,

i find a sensor, the folder "fd" will be increase 3 inode.

when i close search, these inode will be release.

When i connect to HeartRate sensor, the fd will incress 3 inode,

but i release hrpcc, these inode no be released,

=================================================================================

When the inode's number over 1024, the "com.dsi.ant.plugins.antplus" will be crash, so SQLiteDatabase cannot open file.

My question is:
1. Is "com.dsi.ant.plugins.antplus" not close some file, when i release hrpcc?
2. How to solved it?

More information:
i try ANT+ Plugins Service: 3.6.0, also had same issue.

Thanks
Henry
