Problems with installing rJava package

I have tried to call the library xlsx, since I want to save data in multiple-sheets excel files, but I got a Java-related error. Even when I run library(rJava) I have this error code:
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/me/Documents/R/win-library/4.0/rJava/libs/x64/rJava.dll':
LoadLibrary failure: The specified module could not be found.
The solutions I have found online are quite old and none helped to solve the issue: I have tried to reinstall Java 64 bit on my OS (Windows 10-64bit), and the package rJava, I have tried to set Java home with Sys.setenv(JAVA_HOME="C:\Program Files\Java\jre1.8.0_271\") without success. I use R 64 bit.
Do you have any suggestions?

Finally, the solution reported here worked for me. The most important thing is to download the offline version of Java

Unknown error in android studio while installing the debug apk

I'm a beginner in Android studio, and I beg pardon for and writing errors. While trying an ecommerce app to install, I'm getting this error, however I tried searching web for the same, yet could not find it. Can you please help me what this error is about? Earlier this project used Session manager to authenticate, I tried to use Firebase when I faced this issue. Please post any related link.

Android app with Oracle MAF, build.xml not found

I'm currently developing an Android (API 21) app on Eclipse OEPE (Mars) using a 64-bit Win7. The SDK was downloaded and installed by Android Studio (with all the platform-tools and build-tools). I have had no trouble writing the app, but as soon as I try to debug it as described here (Step 6), I get the following error:
BUILD FAILED
{WorkspacePath}\HelloWorld\.main.android.1\bin\build.xml:3: The following error occurred while executing this line:
{WorkspacePath}\HelloWorld\.main.android.1\bin\build-set-globals.xml:67: Cannot find C:\AndroidSdk\tools\ant\build.xml imported from {WorkspacePath}\HelloWorld\.main.android.1\bin\build-set-globals.xml
Total time: 895 milliseconds
(I'm the one who replaced the path to the workspace with {WorkspacePath}).
I have no idea what's going on and couldn't find anything on internet; any suggestion?
EDIT: I forgot to mention it, but the thing that is bothering me the most is that there's no "ant" folder in {SDKPath}/tools

Phonegap 3.3 cannot add platform

I have upgraded my Phonegap running on Windows 7 to the currently latest version to 3.3.0. I could create a project without any issue but when I try to add a platform say "android" an error occurs. Shown below is the error I get when I run "cordova platform add android" command on command promt on Windows 7. Please help.

I had exactly this problem today. Turned out I had white space in the path variable for \android-sdk\tools (in windows 7 environment variables). Check the android batch file runs, ie type android in a command prompt in any directory, and also adb for the platform-tools path. A similar question is answered here < An error occured during creation of android sub-project >.

Here is a blog about installing it from start to finish with a little more detail than phonegap/cordova docs offer. A lot easier than piecing together the different stack questions: http://www.andrewsavory.com/blog/2013/2517
