Renderscript c style pointer usage performance issue

↘锁芯ラ 提交于 2019-12-04 06:55:55
问题 In render script, I am using bound pointers to iterate over a large image. The problem is in the array access performance. ... for(int i=0; i < channels; i++) { sum += (input[i*input_size]) * mulValue; } ... For example, when the input_size is 12288 it takes 1.5 seconds to complete script, but when the input_size is 12280 it takes ~0.5 seconds. What can cause such a mystery behavior? 回答1: Understanding the performance implications of what you write in RenderScript (or openCL) is complex. Just

Gradle conflict when using admob 15.0.0 with the lastest support library

家住魔仙堡 提交于 2019-12-04 04:25:32
I am using 'com.google.android.gms:play-services-ads:12.0.1'. and android support version 27.1.1. when I try to upgrade my ads library to the latest (15.0.0) I get an error saying that I must use the same version specification. See image below. Is there a way to use the latest version for both the supportLibraries and the play-services-ads ?

How to use android support library correctly

Deadly 提交于 2019-12-04 04:16:54
I'm working my way through Professional Android 4 Application Development. Chapter 4 modifies the To Do List app to use fragments, but I'm trying to test on a Gingerbread device. There's mention in the book of using support libraries to allow using Android v3 or v4 features on a lower version device, but it's not covered very well. I'm running into a problem specifically with: // Get references to the Fragments android.app.FragmentManager fm = getFragmentManager(); ToDoListFragment todoListFragment = (ToDoListFragment) fm.findFragmentById( R.id.ToDoListFragment ); I've got these imports at the

Styling the SearchView Widget using support library v21

主宰稳场 提交于 2019-12-04 03:26:42
I'm trying to style the SearchView widget using the new AppCompat v21, but I'm facing some problems. No matter what layout I set on "suggestionRowLayout" attribute, it does nothing at all. The suggestion dropdown list of the SearchView remains the same way. Other problem that I'm having is when the "accent color" is the same color as the "primary color", in the searchview is impossible to distinguish where is the caret. Do you know how can I change the accent color in the SearchView to only be applied there? I've found that Play Music has the same problem. I'm following the guide from Android
