jetbrain-agent.jar破解文件影响Pycharm2021.3.3的启动解决方案

使用everything工具全文搜索pycharm64.exe.vmoptions文件，如果旧版本有使用jetbrain-agent.jar文件，则直接删除相关文件即可恢复启动。

Qt For Android在Window中用脚本批量编译参考

想得太天真了，以为在Windows解决个别仓库的脚本编译问题，就可以一劳永逸地在Window中自由开发安卓了，当连接的第三方库越多，越会发现选择在Windows中开发安卓是多么悲壮的事情，有些库是无法在windows中编译的如openssl。

如果非要在Windows中开发呢？有一个方案就是在Linux编译，生成库文件，在Windows中使用，但那又苦呢？

——————————————————————

几经波折及艰难的研究Android编译过程，最后总算编写出完整的、能在Windows运行的与Qt默认方式编译一致的脚本【网上也有Nijia的编译方式】，具体如下，

@echo off
set path_script=%~dp0

cd /D %path_script%
rd /s/q "%path_script%\build"
rd /s/q "%path_script%\android"

md "%path_script%\build"
cd /D "%path_script%\build"

if not exist "%ANDROID_SDK_ROOT%" (
    echo "not exist path:%ANDROID_SDK_ROOT%"
    pause
)

if not exist "%ANDROID_NDK_ROOT%" (
    echo "not exist path:%ANDROID_NDK_ROOT%"
    pause
)

setlocal enabledelayedexpansion
for %%i in ("x86","armeabi-v7a","arm64-v8a") do (     
    cd %path_script%
    rd /s/q "%path_script%\build"   
    md "%path_script%\build"
    if %%i=="x86" (
        echo "abi type:x86"
        set arch=x86
        set abi=x86
    )
    if %%i=="armeabi-v7a" (
        echo "abi type: armeabi-v7a"
        set arch=armv7
        set abi=armeabi-v7a

        set arch=arm64_v8a
        set abi=arm64-v8a
    )
    set QTDIR=%QT_ROOT%\5.12.12\android_!arch!
    if not exist "!QTDIR!" (
        echo "not exist path:!QTDIR!"

解决方案

断网重装可以解决，因为不断网时，系统获取升级文件，升级了内核很多新问题，产生冲突了。
