            I'm not sure what you're using to code, but in order to set it in Android Studio, open the manifest of your project and under the "activity" section, put android:exported="true"(or false if that is what you prefer). I have attached an example.

            I had the same issue on my system.

            It appears the problem was the use of the "3.2.0" version of "asciidoctor" plugins. The gradle version I'm currently using is "7.2".

            This is the plugins section that was causing the problem:



            Unable to find out where reflections-maven plugin comes from
            Asked 2022-Jan-02 at 13:34

            There executes a particular Maven plugin and I struggle to find out where it comes from to either remove or replace it as its compile dependency link is broken. I am talking about org.reflections:reflections-maven:0.9.8 that depends on org.jfrog.jade.plugins.common:jade-plugin-common:1.3.8 which Maven is not able to download from the central repository as the link redirects to OpenMind location and results in 404 (link).

            Instead of including such JAR in the project structure, I would rather figure out where is reflections-maven plugin defined as this plugin is discontinued (GitHub) but somehow is executed during the build (mvn clean install).

            With Help:Effective-Pom:

            mvn -Dverbose=true -Doutput=./effective-pom.xml help:effective-pom

            We can analyze our "effective pom" (Pom#inheritance, Pom#super-Pom).

            • The verbose flag will also add the source pom (artifact) as a comment to each output line.
            • output sets an output file. (default: prints to console)

            "inter alia" it allows us to locate/override any inherited plugin/dependency/"pom element".

            Unfortunately the output generates:

            • for "trivial" projects "hundreds" lines of pom.
            • for "non-trivial" (spring-boot-starter), it gets easily into "ten-thousands" (lines of pom).

            In intellij we have a "Show effective Pom" command, which basically invokes the mentioned goal and shows the output (in community edition unfortunately!?) without "verbose".

            netbeans has a "Effective" tab in its "Pom Editor":

            • scrolling/cursoring is here also "cumbersome", but we have "full":
            • "Navigation" (window) support
            • Text search
            • Code hints, etc...

            (, "Graph" view also very nice...(and unique feature among "maven IDES (that i know)", and it can be installed un-rooted;)!


            So the mojo seems to work as documented:

            boolean (since:)3.2.0 Output POM input location as comments.

            Default value is: false.

            User property is: verbose.

            For verbose to have an effect, we need to:



            Java method should cache the results
            Asked 2022-Jan-01 at 13:18

            I'm learning programming in the language java.

            I need to write an application that takes a string and returns the number of unique characters in the string. It is expected that a string with the same character sequence may be passed several times to the method. Since the counting operation can be time-consuming, the method should cache the results, so that when the method is given a string previously encountered

            At this stage, my application is already able to count and display characters
