Cordova Android Requirements Failed: "Could Not Find An Installed Version Of Gradle"


Answer :

Solution for linux with apt-get (eg.: Ubuntu, Debian)



I have quite similar problem. I obtained error:



Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle 
in your path, or install Android Studi


but without Exception. I solved it on Ubuntu by 



sudo apt-get install gradle


I found also commands that allows install newest version of gradle in Ubuntu. It works only when first command is executed before (probably some dependecies are incorrect).



sudo add-apt-repository ppa:cwchien/gradle
sudo apt-get update
sudo apt-get install gradle-ppa

If it does not work, try:



export PATH=$PATH:/opt/gradle/gradle-3.5/bin

For CentOS



Instruction of instalation gradle for CentOS is under this link

Update



Now I installing gradle by sdkman it is something like nvm for node.



Install sdkman



curl -s "https://get.sdkman.io" | bash


Install gradle



sdk install gradle 4.0.2


If you have android studio installed then you might want to try: 



export PATH="$PATH:/home/<username>/android-studio/gradle/<gradle-4.0>/bin"


This solved my problem.



For Windows:



-Download last version of Gradle (https://gradle.org/releases)



-Create a folder and unzip files (I use C:\Program Files (x86)\gradle)



-Copy the path with the bin directory included (C:\Program Files (x86)\gradle\bin)



-Set the path C:\Program Files (x86)\gradle\bin (in my exemple) to "Path Environment Variables"



Variable name "Path" and variable value "C:\Program Files (x86)\gradle\bin" for both: User Variable table and System Variables table



You may need to reopen the "Prompt commad line"



To test, type gradle in prompt.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
