I tried the jandroid process. It initially failed with tools/ant/build.xml not found. This seems to be expected:

https://stackoverflow.com/questions/42912824/the-ant-folder-is-suddenly-missing-from-android-sdk-did-google-remove-it

Android team has decided to remove all old and obsolete scripts from SDK in march release of 25.3.0 SDK Tools

Changes:

    Obsolete/deprecated tools have been removed:
        android
        ddms (instead see Using DDMS)
        draw9patch (instead see Draw 9-patch)
        hierarchyviewer (instead see Profile Your Layout with Hierarchy Viewer)
        traceview (instead see Profiling with Traceview and dmtracedump)
        ant scripts
        Project and activity template

I tried he work-around (install tools/ant/build.xml from an older tools release), which failed:

ant release && ./deploy.sh
Buildfile: /home/me/Downloads/Android/jandroid-master/build.xml
[taskdef] Could not load definitions from resource anttasks.properties. It could not be found. [taskdef] Could not load definitions from resource emma_ant.properties. It could not be found.

Poking on the web, it looks as if ant is not well supported any more and folks are migrating to gradle (or Android Studio).

Does this look like the best approach?

Thanks,
David Mitchell

Bill,

Thanks for the nudge.  My old eyes missed the separate git repository for 
jandroid.

All the best,

build.xml should already been there, just
ant release
should build the unsigned apk

It looks like the only place libjpcre.so is used is in jd.  But, jd looks
like
it won't run on the 32 bit default Android distribution.

So, for now, I'll ignore pcre and move on to creating an apk.  Does anyone
have
any suggestions for creating a J Android apk from the binaries created by
ndk-build?  It looks like the choices are to use Android Studio, using
gradlew
or using ant with some sort of build.xml.

Unless there is a build.xml hiding somewhere, all of these look like they
would
require reverse-engineering the current distribution J Android APK.

I used that Android.mk for pcre2.  The Android build references both
pcre and
pcre2:

1. make a symlink in jni folder

$ cd jni
$ ln -sf ../../jsrc .
$ ln -sf ../../hostdefs.
$ ln -sf ../../netdefs .
$ ln -sf ../../../../src/pcre .
$ ln -sf ../../../../src/pcre2 .
$ cd ..

2. build using ndk in the current folder

$ ndk-build

I tried using the same Android.mk with pcre, but it did not work well.

Thanks,

I have almost gotten this to build.  The last step I have is finding
Android.mk
for pcre.

Any help would be appreciated.
