Simple Example of accessing Java classes from Python programs, pythonjava

from jnius import autoclass>>> Stack = autoclass('java.util.Stack')>>> stack = Stack()>>> stack.push('hello')>>> stack.push('world')>>> stack.pop()'world'>>> stack.pop()'hello'

In the above Code, we use the autoclass function to create a type proxy, which corresponds to all the methods and field attributes of the Java. util. Stack class in java.

OK. Maybe you want an Android-related example. Here:

from jnius import autoclassfrom time import sleep MediaRecorder = autoclass('android.media.MediaRecorder')AudioSource = autoclass('android.media.MediaRecorder$AudioSource')OutputFormat = autoclass('android.media.MediaRecorder$OutputFormat')AudioEncoder = autoclass('android.media.MediaRecorder$AudioEncoder') # Record the Microphone with a 3GP recordermRecorder = MediaRecorder()mRecorder.setAudioSource(AudioSource.MIC)mRecorder.setOutputFormat(OutputFormat.THREE_GPP)mRecorder.setOutputFile('/sdcard/testrecorder.3gp')mRecorder.setAudioEncoder(AudioEncoder.ARM_NB)mRecorder.prepare() # Record 5 secondsmRecorder.start()sleep(5)mRecorder.stop()mRecorder.release()

Now, you can get more examples from the document.

We can map Java/Python types, native arrays, and support method overloading. We use Cython + JNI internally, so the minimum consumption performance is.

At the same time, the Python for android library has been completed and can be obtained from github.
