Running an image algorithm on an Android phone

Debug image processing algorithm on PC I want to run on the Android phone and see how fast it takes a few steps.

1. Build an Android application, call the NDK code for your well-written image algorithm

2. Then put your code into the Jni file, write the android.mk, and then the Cgywin build. So for Android calls

3. Then compile your Java code into an apk and pull it to the phone to see the results.

In general, if you do not optimize, directly in the mobile phone running on the PC code, the results are generally miserable, generally need to optimize for the algorithm, fixed-point, neon,opencl and so on parallel computing, improve the parallel degree of the algorithm to improve the speed of operation.
