Generally to debug dEQP android CTS graphics tests, we give command line options to the activity which select the testcase and other test parameters.

as the default activity launch will test the full package which will be very large.
so if option to give command line arguments while starting activity will help in such use cases.

example:
we start the dEQP application like below.

adb shell am start -n com.drawelements.deqp/android.app.NativeActivity -e cmdLine "'binaryname --deqp-watchdog=enable --deqp-log-filename=/sdcard/dEQP-Log.qpa --deqp-gl-config-name=rgba8888d24s8ms0 --deqp-case=dEQP-GLES3.functional.fragment_ops.blend.fbo_srgb.equation_src_func_dst_func.add_constant_alpha_constant_alpha'"
