Why does my android app report that it cannot "find" my own class? possibly related to proguard? -


im developing android app, , started using proguard due "# of classes" library contained.

in process, have been able add proguard rules , recompile app , "run" it.

only each time "run" it, errors out , reports 

caused by: java.lang.classnotfoundexception: didn't find class "com.mycompany.mymodule.utils" on path: dexpathlist...

since proguard has been implemented in order reduce total number of classes, use proguard on every build. dollars donuts problem lies in file - because app ran smoothly before added. have added following lines proguard.pro file in android studio try force resolved:

-keepclassmembers class com.mycompany.mymodule -keep public class * extends android.app.activity -keep public class * extends android.app.application  -keepclasseswithmembers class com.mycompany.mymodule.** { *; } -keepclasseswithmembers class com.mycompany.mymodule.utils {*;}

however, not solve problem.

i @ loss because application errors out on startup. have ideas on can fix this?

if classnotfoundexception, should keep class this:

-keep class com.mycompany.mymodule.utils

the option -keepclassmembers keeps specified class members (fields , methods).

the option -keepclasseswithmembers keeps classes have specified class members (and members).

see proguard manual > usage > overview of keep options.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
