Delphi 11: Find correct toolsversion for MSBuild programmatically

We're upgrading to Delphi 11.1 from 10.4.
We have a few scripts which build and deploy Android projects. They assemble an msbuild command that looked like this:
msbuild someproject.dproj /v:q /p:Platform=Android /t:Build;Deploy /p:Config=Release /p:BT_BuildType=AppStore
With 11.1, this throws an error message:
C:\Program Files (x86)\Embarcadero\Studio\22.0\bin\CodeGear.Common.Targets(940,7): error MSB4036: The "XmlPeek" task was not found. Check the following: 1.) The name of the task in the project file is the same as the name of the task class. 2.) The task class is "public" and implements the Microsoft.Build.Framework.ITask interface. 3.) The task is correctly declared with <UsingTask> in the project file, or in the *.tasks files located in the "C:\Windows\Microsoft.NET\Framework\v2.0.50727" directory. [someproject.dproj]
Now, C:\Program Files (x86)\Embarcadero\Studio\22.0\bin\rsvars.bat, which is used by all of our build scripts, explicitly sets the .NET framework as below:
#SET FrameworkDir=C:\Windows\Microsoft.NET\Framework\v4.0.30319
#SET FrameworkVersion=v4.5
After some research, I hit on the idea of adding a toolsversion parameter to the msbuild command as below, and this worked:
msbuild someproject.dproj /v:q /p:Platform=Android /t:Build;Deploy /p:Config=Release /p:BT_BuildType=AppStore /toolsversion:4.0
This is all well and good, but I would prefer not to hard-code the toolsversion number in the script(s).
Is there a way I can programmatically obtain the correct value of the toolsversion that Delphi itself is using when it generates builds, etc.?
I assume that just finding the highest .NET version installed will not suffice (and even then, one has to "translate" that to a toolsversion). It has to marry up with whatever Delphi is doing (e.g., in the CodeGear.Common.Targets file referenced in the original error message).

This is a bug in Delphi 11.1 that has at least 3 bug reports: RSP-37855, RSP-38466, and RSP-38467.
You can add /tv:4.0 to your MSBuild command line, or modify the first line in the .dproj file to:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="4.0" DefaultTargets="Build">

Assuming that rsvars.bat has been run,
FOR %%v IN ("%frameworkdir%") DO SET "toolsversion=%%~nv"
ECHO msbuild ...blah... /toolsversion:%toolsversion:~1%
The variable frameworkdir will be set by rsvars.bat. The for command parses its value (eg. C:\Windows\Microsoft.NET\Framework\v4.0.30319 as though it is a filename, and picks v4.0 as the "filename" (~n modifier [filename] of the metavariable %%v)
Then use the value assigned to toolsversion, starting at character 1 (where the first character is "character 0")
--- Given more info in comment
FOR %%v IN ("%frameworkdir%") DO ECHO %%~nxv|FINDSTR /R ".*\..*\.">nul&IF ERRORLEVEL 1 (SET "toolsversion=%%~nxv") ELSE SET "toolsversion=%%~nv"
Oh ye of little faith :)

How to generate javadocs for android project

I followed all the instruction given on stackflow, but unfortunately not able to generate doc file for my android project.
If I am not mentioning class path on last step of java doc generation, then getting "Android reference" error.
And if using it, then getting "javadoc: error - The -classpath option may be specified no more than once." error.
Using classpath:
-classpath "D:\Android 4.2 SDK\android_sdk\platforms\android-15\android.jar"
Am I using correct class path command ?
Please help me out.
Environment used:
Eclipse indigo

If you use Intellij IDEA go to Tools - Generate JavaDoc... Specify all the settings and set params: -bootclasspath [path]\android-sdk\platforms\android-{version}\android.jar -encoding UTF-8 -docencoding utf-8 -charset utf-8
More information is in this post.

Have You followed these steps (from www.mtholyoke.edu)? This works on my Project....if not and You get an error, please write here which error You get.
Project -> Generate Javadoc
In the "Javadoc command" field - browse to find javadoc.exe
• On the computers in the Clapp CS lab that is C:\JBuilderX\jdk1.4\bin\javadoc.exe
• On other computers it would be \bin\javadoc.exe
Check the box next to the project/package/file for which you are creating the javadoc
In the "Destination" field browse to find the desired destination (for example, the root directory of the current project).
Leave everything else as it is.
Click "Finish"
Javadoc should be in the destination folder. Open "index.html"
EDIT
I found a thread here in Stackoverflow with a lot of tipps, try this:
Javadoc in Eclipse failing to recognize packages
NEXT EDIT
It is only a possibility, but You specified Your classpath as:
"D:\Android 4.2 SDK\android_sdk\platforms\android-15\android.jar"
I know that eclipse got some problems with spaces inside a path. So the first part "Android 4.2 SDK" has to be specified without spaces, maybe here is the issue. But be aware, if You change this path, You have to set everywhere the new path where You have definded it.

I'm using the command line. I have also updated to Eclipse Kepler. It seems to execute javadoc differently? I'm investigating. But try this:
read the javadoc manual. It's confusing and doesn't tell you what to do, but, here's an example that should get you going.
Create a file called "options"
Add to the file this:
-d target-bin
-stylesheetfile style.css
-use
-splitindex
-windowtitle 'My Project Name Class Specification'
-doctitle 'My Project Name Class Specification'
-header '<b>My Project Name</b><br><font size="-1">0.1.5-alpha</font>'
-bottom 'Copyright 2014 My Company or Myself. All rights reserved.'
-group "Group Of Packages" "com.mypackage.*"
-overview overview.html
-exclude 'android'
-subpackages 'com.mypackage:android'
-charset utf-8
-encoding UTF8
-quiet
-sourcepath ../myProject/src;..\..\..\android-sdks\sources\android-19
Then on the command line type:
javadoc #options
Now, in Kepler, the "Generate Javadoc" dialog box says "What is the javadoc command line"...I suspect I'll have to type something like this. But don't know.
Hopefully this quick example will give you a start on how to get it done for your purposes.
By the way, I created a generic Eclipse project called "javadoc" in my Workspace so I could manage the files.

Convert word and excel to html on android

I would like to convert word and excel documents to html to show them in the browser in my android app.
I found apache poi library, but it converts practically only text without object like forms, diagrams, wordart etc. Or is it possible and I forgot something?
I found also apache tika, but when I added that library to my project I could'nt compile it because of java heap space error (I have in my eclipse.ini file set Xms768m and Xmx2048m). I tried also to load that library at runtime and tried to use dx tool, but I got outofmemory exception.
What could I do with that or is there any possibility to show office documents in the android app?

To handle the OOM error while using the dexer:
there is a dx script used during the builds and it sets a default heapsize for the dexer. The script lives here:
$ANDROID_SDK/build-tools/dx (or dx.bat depending on OS).
There is a section in there that looks like this:
# By default, give dx a max heap size of 1 gig. This can be overridden
# by using a "-J" option (see below).
defaultMx="-Xmx1024M"
# The following will extract any initial parameters of the form
# "-J<stuff>" from the command line and pass them to the Java
# invocation (instead of to dx). This makes it possible for you to add
# a command-line parameter such as "-JXmx256M" in your scripts, for
# example. "java" (with no args) and "java -X" give a summary of
# available options.
javaOpts=""
Maybe try changing javaOpts to -Xmx2048M or something like that.

Porting cURL to Android with NDK

Good day to you. I'm currently struggling at porting cURL onto my Android app - many subjects do talk about this, but no single post or tutorial or whatever does clearly say what to do or just don't work at all.
I do own every single tool needed, have the latest version of cURL (7.28.0). I tried to do it using cross-compiling and a toolchain (part that work good) but when I'm trying to configure the curl-7.28.0, the ./configure --host=arm-linux-androideabi (or any argument that is pass) return the following error :
./configure: line 20: $'\r' : unknown command
./configure: line 35: Syntax error near unexpected token « newline »
'/configure: line 35: ` ;;
If someone had already gone through this and does have the memories of the steps he followed or knows what I do wrong, it would be a blessing if you could help my poor soul !
Thanks in advance.
Note : I'm using Cygwin.

Since you are using Cygwin, I suspect that you have tonj convert all the newlines to the windows format for it to work:
It seems that configure has only \r, or so called "carriage returns", as new line character. This is actually the notation used by OSX. Most *nixes use just a single newline character to work (\n). Only windows needs both: a "carriage return" and a newline character: e.g. \r\n.
You can use any professional text editor to change this, for example notepad++.

Looks like a newline issue in whatever file configure is reading. On Windows, lines in text files are terminated with CR/LF (\r\n) - many Unixy tools choke on that.
Visual Studio, among other tools, can recode line termination. Open a file, File\Advanced Save Options, choose Unix line format, then save.
On *nix there's a tool called dos2unix that does the same.

Cannot compile system app (Phone) using maven - EventLogTags cannot be resolved

this is related to my previous question. I'm trying to build Phone application from android 4.0.4 using maven (I'm adding framework_intermediates as dependency, so internal apis problems are solved), and I ran into this problem. Some parts of the logs are as follows:
Phone/src/com/android/phone/CallNotifier.java:[601,32] cannot find symbol
symbol : variable EventLogTags
(the corresponding line in CallNotifier.java is: EventLog.writeEvent(EventLogTags.PHONE_UI_MULTIPLE_QUERY); )
Phone/src/com/android/phone/InCallScreen.java:[723,28] cannot find symbol
symbol : variable EventLogTags
(the corresponding line in InCallScreen.java is: EventLog.writeEvent(EventLogTags.PHONE_UI_ENTER); )
So... it cannot find the class EventLogTags. There is actually a file Phone/src/com/android/phone/EventLogTags.logtags which has the following contents:
# See system/core/logcat/event.logtags for a description of the format of this file.
option java_package com.android.phone;
70301 phone_ui_enter
70302 phone_ui_exit
70303 phone_ui_button_click (text|3)
70304 phone_ui_ringer_query_elapsed
70305 phone_ui_multiple_query
Apparently, this file tells the system to use some particular tags to log important events in the system. I did a full grep, but could not find any file which defines the values PHONE_UI_ENTER, PHONE_UI_MULTIPLE_QUERY, etc. These are just logs, so I could just comment out these and get it working. But I don't want to do this because I need to build this inside the entire aosp later on. So my question is, how do I get this to compile using maven, without modifying any file?

The Android build system code-generates a Java class out of .logtags files if needed. See: https://github.com/android/platform_build/blob/master/core/base_rules.mk
You will need to decipher the make rules and run that code generation yourself, I imagine.
