the yellow highlighted portion shows file indeed in same project, in different package, red line represents code that's trying use missing class called.
i've considered may problem manifest declaration, can't find wrong - may wrong, i'm including condensed version containing relevant bits below.
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="piccolo.android.panda18" android:versioncode="1" android:versionname="1.0"> <activity android:name="obdtaximeter" /> <activity android:name="obd.configactivity" /> <service android:enabled="true" android:name="obd.mockobdgatewayservice" /> <service android:enabled="true" android:name="obd.obdgatewayservice" /> </application> </manifest> i've tried cleaning , rebuilding (too many times count). made sure build path correct (in terms of appcompat libraries, export order , whatnot), in case, i'm including screenshot of "order , export" screen eclipse below.
i've checked classes.dex file, , find obdgatewayservice class listings inside it.
listing of class in classes.dex:

start intent this:
intent intent = new intent(); intent.setclassname("obd", "obd.obdgatewayservice"); startservice(intent);
