How to detect if it is Recents button, Multi Window mode or home button onUserLeaveHint()

In my app, I am relying on onUserLeaveHint() method when the user presses the home button, but this method is also being called when you are starting multi window mode in android 7.0 by long pressing "recents button" (which I don't want to perform same thing that I do when home button been pressed). So I want to know if there is a way to detect which is which. Cheers!
Note: onMultiWindowModeChanged() being called after onUserLeaveHint()

I think this is what you're looking for.
HomeWatcher mHomeWatcher = new HomeWatcher(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {
#Override
public void onHomePressed() {
// do something here...
}
#Override
public void onHomeLongPressed() {
}
});
mHomeWatcher.startWatch();

import android.content.IntentFilter;
import android.util.Log;
public class HomeWatcher {
static final String TAG = "hg";

public HomeWatcher(Context context) {
mContext = context;
mFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
}
public void setOnHomePressedListener(OnHomePressedListener listener) {
mListener = listener;
mRecevier = new InnerRecevier();
}
public void startWatch() {
if (mRecevier != null) {
mContext.registerReceiver(mRecevier, mFilter);
}
}
public void stopWatch() {
if (mRecevier != null) {
mContext.unregisterReceiver(mRecevier);
}

#Override

public interface OnHomePressedListener {

Google recognizer and pocketsphinx in two different classes, how to loop them?

Yesterday i ask a simplified question of my problem, but think its too simplified.
What my programm should do, is to hear a keyword and when he hear it, he should listen to what i said. (like if you told to siri or google now, by saying siri or ok google).
I'm using pocketsphinx for the keyword and the google speechrecognizer for the longer parts. It works, but only for one time. The pocketsphinx is in the MainActivity and the google recognizer is in an extra class (Jarvis).
The programm starts with the pocketsphinx listener, when he hear the KEYPHRASE, he starts the google listener by calling jarvis.startListener() (by the next()-method) and there is the problem, when the googlelistener is done, i dont come back from the Jarvis-class to the MainActivity to call the next() method again.
(when the google recognizer is done, the last things he do is in the onResult() in Jarvis-class, but from there i cant call the next()-method from MainActivity-class)

You can store reference to the main activity in Jarvis object in a field:
class Jarvis {
....
private MainActivity m;
....
public Jarvis(MainActivity m) {
this.m = m;
}
....
public void onResults(Bundle results) {
....
m.next();
}
You can also send intents to the main activity as described here. This might be overkill in your case though.

Cordova 3 Android plugin - how to call a function in main activity?

Edit: User QuickFix's answer worked for me. Code right at the bottom of this question.
I am trying to write a Cordova 3 Android plugin that makes normal and custom Toast. However, I am just a front-end developer and very new to Cordova and Android. I am still learning and would appreciate any help you can give.
So far I have managed to do these 2 tasks individually and successfully:
write a function in the main activity that makes normal and custom Toast (the custom Toast is simply a RelativeLayout in /res/layout that shows an icon and some text).
write a Cordova plugin by following Devgirl's tutorial: How to Write a PhoneGap 3.0 Plugin for Android.
My problem now is - how do I get the plugin to call the showCustomToast() function in the main activity? As you can see in Code block #2 below, I ran into the problem of how to even get the main activity so I could call showCustomToast(). Here is the extract of how I am currently doing this:
// Problem?
HelloCordova main = (HelloCordova) cordova.getActivity();
main.showCustomToast(toastTitle, toastText, duration);
I have to cast cordova.getActivity() to HelloCordova, otherwise it won't recognise that it has the showCustomToast() function. But surely this is not the correct approach, although it does "work", ie, I am able to get custom Toast to show in the app. I just can't help but feel that I've gone about this completely the wrong way. It's not exactly a reusable plugin at the moment!
I would be very grateful if someone could set me on the right path of how to achieve this. For example, should I give up on the plugin completely and just do this instead?
This is my first Stackoverflow question so please let me know if I should change or clarify anything. Thank you for reading!!
Here's my existing code:
Code block #1
This HelloCordova class was automatically generated when starting a new Cordova project. I added the showCustomToast() function.
package io.cordova.hellocordova;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.widget.Toast;
import org.apache.cordova.*;
public class HelloCordova extends CordovaActivity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
super.init();
// Set by <content src="index.html" /> in config.xml
super.loadUrl(Config.getStartUrl());
//super.loadUrl("file:///android_asset/www/index.html")
}
public void showCustomToast(String toastTitleText, String toastDescText, int toastDuration) {
Toast toast = new Toast(this);
toast.setDuration(toastDuration);
LayoutInflater inflater = getLayoutInflater();
View appearance = inflater.inflate(R.layout.toast_layout, (ViewGroup) findViewById(R.id.toastRoot));
toast.setView(appearance);
TextView toastTitle = (TextView) appearance.findViewById(R.id.toastTitle);
toastTitle.setText(toastTitleText);
TextView toastDesc = (TextView) appearance.findViewById(R.id.toastDescription);
toastDesc.setText(toastDescText);
toast.show();
}
}
Code block #2
The Java part of the Cordova plugin.
package com.example.plugins.toast;
//Problem?
import io.cordova.hellocordova.HelloCordova;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.content.Context;
import android.util.Log;
import android.widget.Toast;
public class ToastPlugin extends CordovaPlugin {
final String LOG_TAG = "ToastLog";
public static final String ACTION_NORMAL_TOAST = "normalToast";
public static final String ACTION_CUSTOM_TOAST = "customToast";
#Override
public boolean execute(String action, JSONArray args,
CallbackContext callbackContext) throws JSONException {
final JSONObject arg_object = args.getJSONObject(0);
final String toastTitle = arg_object.getString("toastTitle");
final String toastText = arg_object.getString("toastText");
final String toastDuration = arg_object.getString("toastDuration");
final CallbackContext ctx = callbackContext;
try {
if (ACTION_NORMAL_TOAST.equals(action)) {
Log.d(LOG_TAG, "Normal toast: " + toastText);
Runnable runnable = new Runnable() {
public void run() {
Context context = cordova.getActivity()
.getApplicationContext();
int duration = Toast.LENGTH_SHORT;
if (toastDuration.equals("LONG")) {
duration = Toast.LENGTH_LONG;
}
Toast.makeText(context, toastText, duration).show();
}
};
this.cordova.getActivity().runOnUiThread(runnable);
callbackContext.success();
return true;
} else if (ACTION_CUSTOM_TOAST.equals(action)) {
Log.d(LOG_TAG, "Custom toast: " + toastTitle + ": " + toastText);
Runnable runnable = new Runnable() {
public void run() {
int duration = Toast.LENGTH_SHORT;
if (toastDuration.equals("LONG")) {
duration = Toast.LENGTH_LONG;
}
//Problem?
HelloCordova main = (HelloCordova) cordova
.getActivity();
main.showCustomToast(toastTitle, toastText, duration);
ctx.success();
}
};
this.cordova.getActivity().runOnUiThread(runnable);
callbackContext.success();
return true;
}
callbackContext.error("Invalid action");
return false;
} catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
callbackContext.error(e.getMessage());
return false;
}
}
}
Edit: Here is the solution that worked for me. As QuickFix mentioned in their answer below, the custom toast code is now in the plugin.
package com.example.plugins.toast;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.content.Context;
import android.content.res.Resources;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class ToastPlugin extends CordovaPlugin {
final String LOG_TAG = "ToastLog";
public static final String ACTION_NORMAL_TOAST = "normalToast";
public static final String ACTION_CUSTOM_TOAST = "customToast";
#Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
final JSONObject arg_object = args.getJSONObject(0);
final String toastTitle = arg_object.getString("toastTitle");
final String toastText = arg_object.getString("toastText");
final String toastDuration = arg_object.getString("toastDuration");
try {
if (ACTION_NORMAL_TOAST.equals(action)) {
Log.i(LOG_TAG, "[Normal toast] toastText: " + toastText);
Runnable runnable = new Runnable() {
public void run() {
Context context = cordova.getActivity().getApplicationContext();
int duration = Toast.LENGTH_SHORT;
if (toastDuration.equals("LONG")) {
duration = Toast.LENGTH_LONG;
}
Toast.makeText(context, toastText, duration).show();
}
};
this.cordova.getActivity().runOnUiThread(runnable);
callbackContext.success();
return true;
} else if (ACTION_CUSTOM_TOAST.equals(action)) {
Log.i(LOG_TAG, "[Custom toast] toastTitle: " + toastTitle + "\n toastText: " + toastText);
Runnable runnable = new Runnable() {
public void run() {
int duration = Toast.LENGTH_SHORT;
if (toastDuration.equals("LONG")) {
duration = Toast.LENGTH_LONG;
}
Context context = cordova.getActivity().getApplicationContext();
Toast toast = new Toast(context);
toast.setDuration(duration);
LayoutInflater inflater = LayoutInflater.from(context);
Resources resources = context.getResources();
String packageName = context.getPackageName();
View appearance = inflater.inflate(resources.getIdentifier("toast_layout","layout",packageName),null);
toast.setView(appearance);
TextView toastTitleView = (TextView) appearance.findViewById(resources.getIdentifier("toastTitle","id",packageName));
toastTitleView.setText(toastTitle);
TextView toastDesc = (TextView) appearance.findViewById(resources.getIdentifier("toastDescription","id",packageName));
toastDesc.setText(toastText);
toast.show();
}
};
this.cordova.getActivity().runOnUiThread(runnable);
callbackContext.success();
return true;
}
callbackContext.error("Invalid action");
return false;
} catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
callbackContext.error(e.getMessage());
return false;
}
}
}

Maybe you could put showCustomToast inside the plugin instead of inside the app?
In that case you will have to replace in the function the R.layout.layoutname and R.id.viewname with
getApplication().getResources().getIdentifier("layoutname","layout",getApplication().getPackageName());
and
getApplication().getResources().getIdentifier("viewname","id",getApplication().getPackageName());

Using IExtendedNetworkService to get USSD response in Android

Thanks!)

Well, I have found the answer.
I just put the link on my gist.
Deactivate messages
USSDDumbExtendedNetworkService.mActive = false;
Send USSD:
Intent launchCall = new Intent(Intent.ACTION_CALL,
Uri.parse("tel:" + Uri.encode(ussdcode)));
launchCall.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
launchCall.addFlags(Intent.FLAG_FROM_BACKGROUND);
startActivity(launchCall);
Activate messages again
USSDDumbExtendedNetworkService.mActive = true;
USSDDumbExtendedNetworkService.mRetVal = null;

how to access com.android.internal.telephony.CallManager?

I am trying to access CallManager class object from com.android.internal.telephony package.
Here is my code:
ClassLoader classLoader = TestActivity.class.getClassLoader();
final ClassLoader classLoader = this.getClass().getClassLoader();
try {
final Class<?> classCallManager =
classLoader.loadClass("com.android.internal.telephony.CallManager");
Log.i("TestActivity", classCallManager);
} catch (final ClassNotFoundException e) {
Log.e("TestActivity", e);
}
Unfortunately, this is throwing a ClassNotFoundException. The same approach allows me to access PhoneFactory, but apparently I'm not allowed to access CallManager.
If I could reach the class, then I'd want to proceed using the class as follows:
Method method_getInstance;
method_getInstance = classCallManager.getDeclaredMethod("getInstance");
method_getInstance.setAccessible(true);
Object callManagerInstance = method_getInstance.invoke(null);
Can anyone help me on this?
Thanks in advance,
Harsha C

I could successfully load CallManager and its methods. However, when I invoke getState(), getActiveFgCallState(), it always return IDLE even when the app receives different call states from TelephonyManager, i.e. TelephonyManager.CALL_STATE_IDLE, TelephonyManager.CALL_STATE_OFFHOOK, TelephonyManager.CALL_STATE_RINGING.
I used the following code to load the class and its methods:
final Class<?> classCallManager = classLoader.loadClass("com.android.internal.telephony.CallManager");
Log.i(TAG, "Class loaded " + classCallManager.toString());
Method methodGetInstance = classCallManager.getDeclaredMethod("getInstance");
Log.i(TAG, "Method loaded " + methodGetInstance.getName());
Object objectCallManager = methodGetInstance.invoke(null);
Log.i(TAG, "Object loaded " + objectCallManager.getClass().getName());
Method methodGetState = classCallManager.getDeclaredMethod("getState");
Log.i(TAG, "Method loaded " + methodGetState.getName());
Log.i(TAG, "Phone state = " + methodGetState.invoke(objectCallManager));
Btw, what I am trying to do is detecting when the phone starts ringing. I saw in the source code that ALERTING is the internal event that I should listen to. Therefore, I tried to use CallManager to get Call.State, rather than Phone.State. I also tried to use registerForPreciseCallStateChanges() of CallManager class but none of approached worked so far.

I had to solve the exact same problem - getting the disconnection cause during call hangup. My solution was to grep the radio logs for the relevant lines. Seems to work - hope it helps.
private void startRadioLogListener() {
new Thread(new Runnable() {
public void run() {
Process process = null;
try {
// Clear the log first
String myCommandClear = "logcat -b radio -c";
Runtime.getRuntime().exec(myCommandClear);
String myCommand = "logcat -b radio";
process = Runtime.getRuntime().exec(myCommand);
Log.e(LogHelper.CAL_MON, "RadioLogProc: " + process);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));
while (true) {
final String line = bufferedReader.readLine();
if (line != null) {
if (line.contains("disconnectCauseFromCode") || line.contains("LAST_CALL_FAIL_CAUSE")) {
Log.d(LogHelper.CAL_MON, "RadioLog: " + line);
radioLogHandler.post(new Runnable() {
public void run() {
consolePrint("Radio: " + line + "\n");
}
});
}
}
}
} catch (IOException e) {
Log.e(LogHelper.CAL_MON, "Can't get radio log", e);
} finally {
if (process != null) {
process.destroy();
}
}
}
}).start();
}

Have you tried this method found here on this blog?
By loading the Phone.apk might be the clue to getting around the ClassNotFound exception error...

I have written a program that recognize the phone calls and list all recent calls in a list. Maybe you can have a look on this code and it can help I think.
All you need is this:
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
but check this example also:
package org.java.sm222bt;
import org.java.sm222bt.R;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;
public class MainActivity extends ListActivity {
private CountryDbAdapter db;
private Cursor entrycursor;
private ListAdapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main);
registerForContextMenu(getListView());
db = new CountryDbAdapter(this);
updateEntry();
}
public void updateEntry(){
db.open();
entrycursor = db.fetchAllEntries();
adapter = new SimpleCursorAdapter(this, R.layout.row, entrycursor, new String[] {"phonenumber"}, new int[] {R.id.number});
setListAdapter(adapter);
db.close();
}
#Override
protected void onResume() {
super.onResume();
updateEntry();
}
public static final int Call = 0;
public static final int SendSMS = 1;
public static final int Share = 2;
public static final int Delete = 3;
public static final int ClearList = 4;
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenu.ContextMenuInfo menuInfo) {
menu.setHeaderTitle("Select:");
menu.add(0, Call, 0, "Call");
menu.add(0, SendSMS, 0, "Send SMS");
menu.add(0, Share, 0, "Share");
menu.add(0, Delete, 0, "Delete");
menu.add(0, ClearList, 0, "Clear all contacts");
}
#Override
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()) {
case Call:
//System.out.println(entrycursor.getString(1));
//EditText number=(EditText)findViewById(R.id.number);
String toDial="tel:"+entrycursor.getString(1);
//start activity for ACTION_DIAL or ACTION_CALL intent
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(toDial)));
//update(entryCursor.getLong(0));
return true;
case SendSMS:
//EditText number=(EditText)findViewById(R.id.number);
//EditText msg=(EditText)findViewById(R.id.msg);
String sendUri="smsto:"+entrycursor.getString(1);
Intent sms=new Intent(Intent.ACTION_SENDTO,
Uri.parse(sendUri));
//sms.putExtra("sms_body", msg.getText().toString());
startActivity(sms);
return true;
case Share:
Intent i=new Intent(Intent.ACTION_SEND);
i.setType("text/plain");
i.putExtra(Intent.EXTRA_SUBJECT, "Hello");
i.putExtra(Intent.EXTRA_TEXT, "Sharing this number"+entrycursor.getString(1));
startActivity(Intent.createChooser(i,
entrycursor.getString(1)));
return true;
case Delete:
db.open();
db.deleteEntry(entrycursor.getLong(0));
db.close();
updateEntry();
return true;
case ClearList:
db.open();
db.deleteEntry();
db.close();
updateEntry();
return true;
default:
return super.onContextItemSelected(item);
}
}
}
and here is the incomming call receiver:
package org.java.sm222bt;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;
public class IncomingCallReceiver extends BroadcastReceiver {
CountryDbAdapter db;
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
{
String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
System.out.println(phonenumber);
db = new CountryDbAdapter(context);
db.open();
db.insertEntry(phonenumber);
db.fetchAllEntries();
db.close();
}
}}

I understand that you want to detect when the call is disconnected. You can instead use the PhoneStateListener.LISTEN_CALL_STATE. For example:
final TelephonyManager telephony = (TelephonyManager)
getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(new PhoneStateListener() {
public void onCallStateChanged(final int state,
final String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.d("TestActivity", "Call disconnected");
break;
case TelephonyManager.CALL_STATE_RINGING:
break;
default:
break;
}
}
}, PhoneStateListener.LISTEN_CALL_STATE);

Use this :
telephone = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
private PhoneStateListener psl = new PhoneStateListener() {
#Override
public void onCallStateChanged (int state, String incomingNumber)
{
state = telephone.getCallState();
switch(state) {
case android.telephony.TelephonyManager.CALL_STATE_IDLE:
if (callsucces ) act();
break;
case android.telephony.TelephonyManager.CALL_STATE_RINGING:
callsucces = true;
break;
case android.telephony.TelephonyManager.CALL_STATE_OFFHOOK:
callsucces = true;
break;
}
}
};
private void call(String pnum) {
try {
callIntent = new Intent(Intent.ACTION_CALL);
callsucces = false;
if (telephone.getNetworkType() != 0) {
if (telephone.getCallState() == TelephonyManager.CALL_STATE_IDLE) {
callIntent.setData(Uri.parse("tel:"+pnum));
startActivity(callIntent);
telephone.listen(psl,PhoneStateListener.LISTEN_CALL_STATE);
}
} else act();
//callIntent.ACTION_NEW_OUTGOING_CALL
} catch (ActivityNotFoundException activityException) {
Toast.makeText(getBaseContext(), "Call failed",Toast.LENGTH_SHORT).show();
act();
}
}

Did you add READ_PHONE_STATE in AndroidManifest.xml ?
I think you miss that one.
