Android round edges on ring shaped progressbar
Just create class called MyProgress in your package .. and paste the following code..

}
and add the following line in res->values->attr.xml under a tag and build it
<declare-styleable name="MyProgress">
<attr name="showProgressText" format="boolean" />
<attr name="progress" format="integer" />
<attr name="secondaryProgress" format="integer" />
<attr name="progressColor" format="color" />
<attr name="secondaryProgressColor" format="color" />
<attr name="backgroundColor" format="color" />
<attr name="primaryCapSize" format="integer" />
<attr name="secodaryCapSize" format="integer" />
<attr name="primaryCapVisibility" format="boolean" />
<attr name="secodaryCapVisibility" format="boolean" />
<attr name="strokeWidth" format="dimension" />
<attr name="textColor" format="color" />
</declare-styleable>
that's it .... and to use in your layout ..
<Your_Package_Name.MyProgress
android:padding="20dp"
android:id="@+id/timer1"
app:strokeWidth="10dp"
app:progress="30"
app:secondaryProgress="50"
app:backgroundColor="@android:color/black"
app:progressColor="@android:color/holo_blue_bright"
app:secondaryProgressColor="@android:color/holo_blue_dark"
app:primaryCapSize="30"
app:secodaryCapSize="40"
app:primaryCapVisibility="true"
app:secodaryCapVisibility="true"
android:layout_width="200dp"
android:layout_height="200dp" />
You can also change all property progrmatically using setMethods()...
feel free to ask anything .. best of luck
[Update 23-01-2016]
finally I uploaded code on github. You can refer it from here https://github.com/msquare097/MProgressBar
Now You can use this ProgressBar by simply writing following line in your app build.gradle file. You don't have to copy above code.
compile 'com.msquare.widget.mprogressbar:mprogressbar:1.0.0'
I was able to achieve this using a layer list, and adding a dot to each side of the line. The first one will be stuck at the top, while the second one will follow the progress as an inset is added inside a rotate element. You will have to adjust it according to the size of your progressbar layout though. Mine is 250dp x 250dp.
progress_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<rotate android:fromDegrees="270" android:toDegrees="270">
<shape
android:innerRadiusRatio="2.55"
android:shape="ring"
android:thickness="15dp"
android:useLevel="true">
<solid android:color="@color/main_color" />
</shape>
</rotate>
</item>
<item android:bottom="211dp">
<shape
android:innerRadiusRatio="1000"
android:shape="ring"
android:thickness="7dp"
android:useLevel="false">
<solid android:color="@color/main_color" />
</shape>
</item>
<item>
<rotate>
<inset android:insetBottom="211dp">
<shape
android:innerRadiusRatio="1000"
android:shape="ring"
android:thickness="7dp"
android:useLevel="false">
<solid android:color="@color/main_color" />
</shape>
</inset>
</rotate>
</item>
</layer-list>
I don't have a secondary process here, but you should be able to adjust it for that as well.
