是仿真软件没有找到一个资源，或者没有获得该资源使用权，或者在测试该资源。

如何屏蔽警告：EmulatorService.cpp：448：找不到证书文件：D:\Android\AVD.android\emulator-grpc.cer安全性将被禁用。？？？我一直想解决我的模拟器的一个问题： Emulator: emulator: WARNING: EmulatorService.cpp:448: Cannot find certfile: D:\Android\AVD.android\emulator-grpc.cer security will be disabled. Emulator: Started GRPC server at 127.0.0.1:8554

手贱更新了android studio过后，编译不报错，只要启动模拟器就会报出两行emulator警告，关掉模拟器也会有警告，之前版本用的都好好的，怎么消除警告问题？ Emulator: emulator: WARNING: EmulatorService.cpp:448: Cannot find certfile: C:\Users\Sawye.android\emulator-grpc.cer security will be disabled. Emulator: Started GRPC server at 127.0.0.1:8554 目前搜遍全网没有解决方法！！！！作者：程程

资源下载链接为： https://pan.quark.cn/s/22ca96b7bd39 使用Android Studio 3.6时，模拟器启动或关闭可能出现如下警告： Emulator: emulator: WARNING: EmulatorService.cpp:448: Cannot find cert …\Users\Sawye.android\emulator-grpc.cer security will be disabled. 该提示意味着安全功能被禁用，旧版本未出现此问题。可尝试以下方法解决：检查证书路径与文件确认 C:\Users\Sawye.android\ 目录存在且包含 emulator-grpc.cer。若缺失，可从其他正常机器复制或重新生成。清理并重建项目在 Android Studio 中执行 Build → Clean Project 与 Rebuild Project，排除缓存或配置错误。更新或重装 Android SDK 打开 SDK Manager，确保 SDK Tools、Emulator 等组件为最新版；必要时卸载后重新安装。升级 Android Studio 官方可能已修复相关 bug，建议检查 Help → Check for Update 并安装最新稳定版。命令行启动模拟器在终端执行： emulator -avd -accel on -gpu on 可绕过 IDE 直接启动，验证是否为界面问题。重置 AVD 打开 AVD Manager，选中设备 → Wipe Data / Reset，恢复默认设置。核查环境变量确认 ANDROID_SDK_HOME、ANDROID_HOME 等指向正确路径，并加入 PATH。

主要介绍了Android Studio 3.6运行模拟器时Emulator警告问题的解决方案,本文给大家介绍的非常详细，对大家的工作或学习具有一定的参考借鉴价值，需要的朋友可以参考下

Gamma Manager is based on Gamma Slider control. This control allows to change gamma monitor on most graphic cards. The goal for this project is very simple and control is for VC6 & VC7. The other day I downloaded a N64 emulator but the screen was so black that I did not see anything. I had thus to find this solution to lighten my screen. I know that the tools of my video chart make it possible to change gamma of my screen, but it is faster with this tool. Implementation The implementation of this slider control is very easy. Import GammaSlider.h and GammaSlider.cpp into your project. Include reference to the class control. Add slider control on a form. Use ClassWizard to declare variable name derived from CGammaSlider control. That's it, enjoy! Under the hood Windows provides two APIs GetDeviceGammaRamp/ SetDeviceGammaRamp to perform gamma correction. In fact we need to have a 3 dimensional buffer of 256 WORD to manipulate gamma correction. To change gamma, it is necessary to change the RGB value of each color contained in the buffer by a float factor between 0.0 and 2.0. Example We need to save current gamma for future restore. Collapse Copy CodeWORD m_RampSaved[256*3]; if (!GetDeviceGammaRamp(::GetDC(NULL), m_RampSaved)) { TRACE("WARNING: Cannot initialize DeviceGammaRamp.\n"); }To change gamma, cycle into ramp buffer and change RGB color where Gamma is the float factor. Collapse Copy CodeWORD ramp[256*3]; for( int i=0; i<256; i++ ) { ramp[i+0] = ramp[i+256] = ramp[i+512] = (WORD)min(65535, max(0, pow((i+1) / 256.0, Gamma) * 65535 + 0.5)); } SetDeviceGammaRamp(::GetDC(NULL), ramp);Now to trap slider control message, we need to use a special message ON_WM_HSCROLL_REFLECT() that can provide message to be dispatched into control class itself.
