Unity Hub 注意事项

1. 查看项目使用的unity editor版本

ProjectSettings/ProjectVersion.txt

2. Unity下载文件有c1后缀, 中国版; 无c1后缀, 全球版; 18及以前的中国版多点东西, 较新的没太大区别;还有个比较重要的是, UnityHub也分中国版和全球版, 中国版Hub能识别中国版和全球版Editor, 并且Hub中内容丰富一点, 包括社区内容之类的;全球版Hub则只能识别全球版Editor。

Android Studio 使用gradle编译app遇到的问题及解决方法

  1. Android Studio gradle:build model长久运行不结束

在gradle.properties,文件中添加内容

org.gradle.daemon=true

在build.gradle(:root)中,可以看到mavenCentral()拖慢，注释mavenCentral()，另外需要镜像

maven { url ‘http://maven.aliyun.com/nexus/content/groups/public/’ }

 

  1. Android Studio: Android Manifest doesn’t exists or has incorrect root tag

点击File / Sync project with Gradle files

 

  1. AndroidManifest.xml – specified for property ‘manifest’ does not exist

Remove this chunk of code from your build.gradle（:root) in the root directory

apply plugin: ‘com.android.application’

and

android
{

compileSdkVersion 21

buildToolsVersion “20.0.0”

defaultConfig
{

applicationId “xxx.xxx.xxx”

minSdkVersion 15

targetSdkVersion 19

versionCode 1

versionName “0.5”

}

}

 

  1. How to add clean task – Task ‘clean’ not found

add below in the build.gradle(:root)

apply plugin:’base’

  1. Entry name ‘AndroidManifest.xml’ collided (Build failed after updating the android gradle plugin to 3.6.0)

add below in the build.gradle(:app)

android
{
packagingOptions
{
exclude
‘AndroidManifest.xml’

}

}

SEGGER编译Nordic nRF示例问题

环境： SEGGER Embedded Studio for ARM v7.10， nRF5 SDK 17.1.0

使用SEGGER编译示例ble_app_uart，出现一下问题及相应的解决思路：

问题1: retarget.c:101:23: error: unknown type name ‘__printf_tag_ptr’

修改retarget.c:99

#if defined(__SES_VERSION) && (__SES_VERSION >= 34000)

#if defined(__SES_VERSION) && (__SES_VERSION >= 34000) && !defined(__SEGGER_RTL_VERSION)

 

问题2:  “.text is larger than specified size” and “.rodata is larger than specified size”

在项目目录下找到flash_placement.xml” 找到两行
<ProgramSection alignment=”4″ load=”Yes” name=”.text” sizeof=”0x4″/>    <ProgramSection alignment=”4″ load=”Yes” name=”.rodata” sizeof=”0x4″ />

将上面的sizeof=”0x4″ 删除

 

问题3: libc_v7em_fpv4_sp_d16_hard_t_le_eabi_balanced.a(fileops.o): in function `putchar’:”

修改”Library I/O” (under Project options >> Code >> Library) from “None” to “RTT”

Unity android 添加虚拟方向盘控制

首先加载CrossPlatformInput资产，将其中Prefabs下面的MobileSingleStickControl添加到游戏场景上。

然后将玩家脚本中的坐标轴获取方法

float x = Input.GetAxisRaw(“Horizontal”);

float y = Input.GetAxisRaw(“Vertical”);

修改如下：

float x = CrossPlatformInputManager.GetAxisRaw(“Horizontal”);

float y = CrossPlatformInputManager.GetAxisRaw(“Vertical”);

如何在google play控制台删除已上传的aab文件

https://stackoverflow.com/questions/45822460/remove-apk-from-library-in-google-play-developer-console 转载

Just go to App bundle explorer and remove the needed abb. You can do it with these steps:

  1. Open Google Play Console
  2. Go to your project
  3. Go to the “Release” section of the side-bar
  4. Go to the “App bundle explorer”
  5. Find the APK/Bundle and click “Delete APK/Bundle”.

Keep in mind that you need to detach the specific APK/Bundle from any draft releases and save it. Otherwise, the delete option will not be available.
