primary.prof.txt is generated from CtsCompilationApp and must be updated if CompilationTargetActivity.java changes:

$ m CtsCompilationApp $ adb install $ANDROID_PRODUCT_OUT/data/app/CtsCompilationApp/CtsCompilationApp.apk

Now run the app manually for a couple of minutes, look for the profile:

$ adb shell ls -l /data/misc/profiles/cur/0/android.compilation.cts/primary.prof

Once the profile appears and is nonempty, grab it:

$ adb pull /data/misc/profiles/cur/0/android.compilation.cts/primary.prof ./

app_used_by_other_app_1.prof.txt and app_used_by_other_app_2.prof.txt are manually constructed for AppUsedByOtherApp. The latter one should be a superset of the former one.
