Chaquopy

This is a minor update to fix issues with non-ASCII text in Python source code (#27).

This version focuses on improving Python standard library functionality:

• The following things now return reasonable values: sys.argv, sys.executable, and platform.platform().
• The following modules now work correctly: sqlite3, ssl (#23), and tempfile. (Requires python.version to be 2.7.14 or 3.6.3.)
• sys.stdout and sys.stderr are now directed to the Android logcat.

It also adds the following feature:

This version adds the following features:

• Python source directory locations can now be configured in the sourceSets block, just like Java.
• Python 2.7.14 is now available.

And fixes the following bugs:

• getClass, when called on a Java object, now returns the Java object class rather than the
  proxy object class.
• Generated static_proxy Java files no longer produce build warnings.
• Pip is now re-run if a local requirements or wheel file changes.
• Missing stdlib modules distutils and doctest have been added (#20). For Python 2 apps, this also requires
  upgrading to Python 2.7.14.

The following packages have been added to the repository:

• mpmath
• sympy

This version adds the following features:

This version adds the following features:

• Apps can now use certain native packages, including NumPy (#14), as well as pure-Python packages which aren’t available from PyPI in wheel format.
  • To see which packages and versions are currently available, you can browse the repository here. To request a package to be added or updated, please visit our issue tracker.
  • The build.gradle syntax for calling pip install has been changed: please see the documentation.
• Zero-initialized Java arrays can now be created in Python, by passing an integer to the array constructor rather than a sequence.

And fixes the following bugs:

• Garbage collection tests often fail on API level 19 and older (fixed as far back as API level 17)

This version adds the following features:

• Support Android Gradle plugin version 2.2
• Support Android Gradle plugin version 3.0 (the demo app now targets this version, but it should still be buildable with versions 2.2 and 2.3)
• Add java.detach function to allow use of the Python API in background threads

And fixes the following bugs:

• test_gil_release_constructor may fail on slow or overloaded device
• Can store wrong object type in arrays on API level 15
• Several multi-threading issues

This version also increases the minimum API level for Chaquopy-based apps from 9 to 15. This is the default for new apps in Android Studio 3.0, and covers 99% of active devices.

This version fixes the following bug:

• Module ImportError no module named six

This version fixes the following bug:

• Implicit relative imports do not work with import hook

This version significantly improves startup performance.  In the demo app, the “Android UI  demo” activity now opens more than twice as fast as in version 0.4.0.

This version adds the ability to inherit Java classes and interfaces in Python classes. This means that Python objects can now be instantiated or accessed by non-Python-aware code, making it possible to write an Android app entirely in Python.

For more details, see the documentation. Or for a complete example, see the “Android UI demo” activity in the demo app.
