4 years ago The REPL code depends on App.context being set in App.onCreate:
Could you have changed anything which affects this?

4 years ago I haven't changed anything in App.java it's the same code. But in repl.py when I'm trying to handler the exception at InteractiveConsole the interpreter is opening fine but not giving any output

4 years ago This is my App.java file
package com.works.python.Activities;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.content.SharedPreferences;
import android.os.Build;
import android.preference.PreferenceManager;
import com.chaquo.python.android.PyApplication;
public class App extends PyApplication {
public static final String DEFAULT_CHANNEL = "default";
public static App context;
public static SharedPreferences prefs;
@Override
public void onCreate() {
super.onCreate();
context = this;
prefs = PreferenceManager.getDefaultSharedPreferences(this);
if (Build.VERSION.SDK_INT >= 26) {
NotificationChannel channel = new NotificationChannel
(DEFAULT_CHANNEL, "Default", NotificationManager.IMPORTANCE_LOW);
((NotificationManager) getSystemService(NOTIFICATION_SERVICE))
.createNotificationChannel(channel);
}
}
}
This is my repl.java file which I named it as IDEActivity.java
package com.works.python.Activities;
import android.app.Application;
import android.os.Bundle;
import android.text.InputType;
import android.widget.TextView;
import com.works.python.Activities.python.utils.PythonConsoleActivity;
public class IDEActivity extends PythonConsoleActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// VISIBLE_PASSWORD is necessary to prevent some versions of the Google keyboard from
// displaying the suggestion bar.
((TextView) findViewById(resId("id", "etInput"))).setInputType(
InputType.TYPE_CLASS_TEXT +
InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS +
InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
}
@Override
protected Class<? extends Task> getTaskClass() {
return Task.class;
}
// Maintain REPL state unless the loop has been terminated, e.g. by typing `exit()`. Requires
// the activity to be in its own task (see AndroidManifest).
@Override
public void onBackPressed() {
if (task.getState() == Thread.State.RUNNABLE) {
moveTaskToBack(true);
} else {
super.onBackPressed();
}
}
// =============================================================================================
public static class Task extends PythonConsoleActivity.Task {
public Task(Application app) {
super(app);
}
@Override
public void run() {
py.getModule("chaquopy.demo.repl")
.callAttr("AndroidConsole",App.context)
.callAttr("interact");
}
}
}
And this is repl.py
from __future__ import absolute_import, division, print_function
from code import InteractiveConsole
import sys
class AndroidConsole(InteractiveConsole):
"""`interact` must be run on a background thread, because it blocks waiting for input.
"""
def __init__(self, context):
InteractiveConsole.__init__(self, locals={"context": context.getApplicationContext()})
def interact(self, banner=None):
if banner is None:
banner = ("Python {} on {}\n".format(sys.version, sys.platform) +
"The current application context is available in the variable 'context'.")
try:
InteractiveConsole.interact(self, banner)
except SystemExit:
pass
Your code looks fine, so I wonder whether App.context is actually being set in Java. Can you verify that using a debugger or a logcat call?
For example, if you changed either of the following things in AndroidManifest.xml:
<application android:name=...<manfest package=...... then App.onCreate might not be running anymore.

4 years ago I used Debugger to get the logs and here it is
public static class Task extends PythonConsoleActivity.Task {
public Task(Application app) {
super(app);
}
@Override
public void run() {
py.getModule("chaquopy.demo.repl")
.callAttr("AndroidConsole",App.context)
.callAttr("interact");
Log.i("Checking", "run: App.Context is called"); //checking if the above statements are executing
}
}and these are the logs. Log is not executed

Thank you @mhsmith . You made it easy for me to decode
