I am working with SpeechRecognizer. The problem was if there is no active internet connection SpeechRecognizer will throw error SpeechRecognizer.ERROR_NETWORK or SpeechRecognizer.ERROR_SERVER.
This is my RecognizerIntent
final Intent recognizerIntent;
recognizerIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "en");
recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, this.getPackageName());
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_PREFER_OFFLINE, true);
And I put recognizerIntent.putExtra(RecognizerIntent.EXTRA_PREFER_OFFLINE, true);
But no luck. again it will throw the same error.
And I got these 2 errors frequently.
SpeechRecognizer.ERROR_RECOGNIZER_BUSY
SpeechRecognizer.ERROR_NO_MATCH
Please help me.
First of all, you need to make sure if you have offline package of language you put to EXTRA_LANGUAGE_PREFERENCE installed on the device.
To enable Offline Speech input in supported devices, follow below steps:
Go to Settings
Click on “Language and input”
On-screen keyboard
Select Google voice typing
Select Offline speech recognition
Install desired language
If it still does not work offline, try to change your EXTRA_LANGUAGE_PREFERENCE value to something more specific, "en-US" for example (That did the trick for me)
And also, if you want to tell SpeechRecognizer wich language it should recognize, I guess you should use EXTRA_LANGUAGE parameter instead of EXTRA_LANGUAGE_PREFERENCE
Hope it will help

What have I done so far:
I am currenctly facing some problems with the launchers.
My application adds shortcuts to the workspace of the launcher (homescreen).
But on some devices (Samsum Duos) for example, the titles and /or icons
are changed back after reboot to my default application one.
So I am currently going through 1000s of lines code in the android
source to identify the problem, but was not able to find it.
I saw in InstallShortcutReceiver
a comment in line 183 that the "name" provided by Intent.EXTRA_SHORTCUT_NAME can in
some situations be used only for comparison etc and will be replaced
with the applications default name.
// This name is only used for comparisons and notifications, so fall back to activity name
// if not supplied
But (my Samsum Duos is rooted) I could find the complete information's
about the cell position and shortcutInfo's inside of the launcher.db.
So it was not gone, after reboot, but maybe only not correct initialized!
First Question:
Does anybody know the reason for a custom, programmatically created shortcut to change the title and or icon back to the application's one that created it?
Next story:
I noticed that this issue was reproducible on my Samsum Duos, so I decided
to exclude the Devices Launcher from my "save launcher" list.
To receive the default launcher I am doing the following:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
ResolveInfo resolveInfo = null;
try {
resolveInfo = context.getPackageManager().resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY); //can return null!
}catch(RuntimeException e){
ExceptionHandler.logAndSendException(e);//package manager has died
return false;
}
But the problem now is, that it always returns that the default launchers
package is: com.android.launcher2.Launcher, which would be the standard
android stock launcher. But I know that Samsum uses the TouchWiz home
launcher, whos Package is located under com.sec.android.app.launcher!
That is also where I found the launcher.db and all its ShortcutInfo's.
2. Second Question
How do I get reproducible the correct default launcher package to identify
which launcher is used?
edit:
I kind of fixed the second problem. Somehow the ResolveInfo I get from
the PackageManager seems to be not reliable.
For the Samsum Duos I get:
resolveInfo.activityInfo.name = com.android.launcher2.Launcher
resolveInfo.activityInfo.packageName = com.sec.android.app.launcher //this is what I need
But for the Redmi MIUI:
resolveInfo.activityInfo.name = com.miui.home.launcher.Launcher //this time I would need this
resolveInfo.activityInfo.packageName = com.miui.home //the packageName is not complete!
I need an unique identifier for the launcher! So I thought activityInfo.name would be the
way to go, but it isn't in some situations. And the packageManager seems to apply to too many devices. Any suggestions?
Cheers!
I am trying to add a button in my application that starts Google Voice Typing (or the default speech recognition). I have tried following this tutorial. This tutorial is incredibly confusing to me. I imported the .jar, and added the necessary permissions, services, and activities to my Manifest. But I can't seem to figure out how to "put it all together". I'm wondering:
Am I supposed to call the inputMethodService from my button click in my Main Activity? Or does my inputMethodService essentially become my Main Activity?
What does IME mean? I tried to Google it, but the definitions it gave me didn't help my understanding.
When I try to copy and paste the whole DemoInputMethodService code into my current activity, I get an error saying I cannot extend InputMethodService inside of this activity. (Which leads back to to ask question one.)
How can I get this to work?
If you want to follow the tutorial that you mention then you need to implement an IME (input method editor) first, see http://developer.android.com/guide/topics/text/creating-input-method.html
This IME can have a regular keyboard look-and-feel or contain just a microphone button.
The user of your app will first have to click on a text field to launch the IME. (Note that there can be several IMEs installed on the device and they have to be explicitly enabled in the Settings.) Then the user will have to click on the microphone button to trigger the speech recognition.
The tutorial provides a jar that lets you directly call Google's recognizer. It would be nicer if instead you called the recognizer via the SpeechRecognizer-interface (http://developer.android.com/reference/android/speech/SpeechRecognizer.html), this way the user can decide whether to use Google's or something else.
The SpeechRecognizer is given a listener which supports the method onPartialResults, which allows you to monitor the recognition hypotheses while the user is speaking. It's up to you how you display them. Note however that the specification of SpeechRecognizer does not promise that this method gets called. This depends on the implementation of the recognizer service. Regarding Google's implementation: what it supports keeps changing unannounced, it does not have a public API nor even release notes.
You might be able to reuse my project Kõnele (http://kaljurand.github.io/K6nele/about/), which contains two implementations of SpeechRecognizer and an IME that uses them. One of the implementations offers continuous recognition of arbitrarily long audio input, using the Kaldi GStreamer server (https://github.com/alumae/kaldi-gstreamer-server). You would need to set up your own instance of the server porting it to the language that you want to recognize (unless you want to use the Estonian server that Kõnele uses by default).
Voice recognition samples are found where you have the android SDK..
example:
$ find $SDK_ROOT/samples -name *recogni*
./android-19/legacy/VoiceRecognitionService/res/xml/recognizer.xml
./android-19/legacy/VoiceRecognitionService/src/com/example/android/voicerecognitionservice
./android-19/legacy/ApiDemos/res/layout/voice_recognition.xml
./android-18/legacy/VoiceRecognitionService/res/xml/recognizer.xml
./android-18/legacy/VoiceRecognitionService/src/com/example/android/voicerecognitionservice
./android-18/legacy/ApiDemos/res/layout/voice_recognition.xml
./android-21/legacy/VoiceRecognitionService/res/xml/recognizer.xml
./android-21/legacy/VoiceRecognitionService/src/com/example/android/voicerecognitionservice
./android-21/legacy/ApiDemos/res/layout/voice_recognition.xml
any one of the services should help show how to do a RecognizerIntent
The "APIDemo" seems to include use of a RecognizerIntent. check the source for that one. Otherwise look into the services and carve them up into an intent.
I had the same issue, but after a long time looking for continuous voice dictation on an activity, I solved that problem using pocketsphinx.
I couldn't find the way to integrate Google Voice Typing on an activity, just on an input method by following that tutorial. If it confuse you, just download this demo and modify it.
Good Luck!
You can trigger an intent from a button listener
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
And the result can be get from
private TextToSpeech mTts;
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
mTts = new TextToSpeech(this, this);
} else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(
TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}

I know there are several Qs here that ask if its possible to add badges to an android app and they all end up with a NO answer...
But somehow the latest Facebook beta version for Android seems to do something which at least look like a badge even if it is not technically exactly that.
In that post one of the commenters says that it is somehow related to TouchWiz.
And also here they mention it as a feature of the "S3 TouchWiz Jelly Bean Addon".
I still would appreciate information on how does this can be done and if there is some API for this that I can use in my own app (when running in an appropriate environment - i.e. the same device where FB demonstrates this behavior) ?
Hi you can use this lib simply.
Support : Sony,Samsung,LG,HTC,Xiaomi,ASUS,ADW,APEX,NOVA,Huawei,ZUK,OPPO
ShortcutBadger
Add :
int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);
Remove :
ShortcutBadger.applyCount(context, 0);
I have figured out how this is done for Sony devices.
I've blogged about it here. I've also posted a seperate SO question about this here.
Sony devices use a class named BadgeReciever.
Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:
Broadcast an Intent to the BadgeReceiver:
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
sendBroadcast(intent);
Done. Once this Intent is broadcast the launcher should show a badge on your application icon.
To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.
There is not a standard way to achieve this; Many makers such as Sony or Samsung have implemented it in their own Android customization.
For example in Samsung, you have to broadcast an intent with BADGE_COUNT_UPDATE action, let MainActivity be your main activity class and count be the number you want to display in your app icon, note that 0 will hide the badge:
Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
intent.putExtra("badge_count", count);
intent.putExtra("badge_count_package_name", context.getPackageName());
intent.putExtra("badge_count_class_name", MainActivity.class.getName());
context.sendBroadcast(intent);
Sony devices uses "com.sonyericsson.home.action.UPDATE_BADGE" action with their custom extras as #Marcus Answered, so you have to add "com.sonyericsson.home.permission.BROADCAST_BADGE" permission to your app manifest and:
Intent intent = new Intent("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", MainActivity.class.getName());
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", String.valueOf(count));
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", context.getPackageName());
context.sendBroadcast(intent);
Note: it's desirable to query your app's data (context.getPackageName(), MainActivity.class.getName()) rather than hardcode it just in case you do some refactoring in the future.
But somehow the latest Facebook beta version for android does just that...
Not according to the forum thread that contains the screenshot that you linked to. Quoting vakama94:
Well, that's actually TouchWiz and not just the app. I have a Galaxy S II running JellyBean 4.1.2 and it makes the same thing but with some other applications
Whether Samsung has a public API to allow apps to publish numbers to be used as badges, I cannot say. This could be something that they did privately with a few firms.
You are welcome to provide evidence of seeing these badges on a stock Android home screen, such as one of the Nexus series devices.
I answer to this assuming that some flutter dev can search this...
In Flutter, you can achieve this by using
Flutter app badger library.
It is as simple as
FlutterAppBadger.updateBadgeCount(1); // show
FlutterAppBadger.removeBadge(); // hide
I need some advice for this matter...
I used the facebook android sdk to create an integration with facebook from my application...I followed this tutorial:
http://www.integratingstuff.com/2010/10/14/integrating-facebook-into-an-android-application/
I would need to implement authentication in one activity and the function postToWall in another.... after authentication i want to send post simply by pressing a button but in other activity, different from that where i do authentication.
is it possible? or with the SDK I'm forced to do everything together in the same activity?
thanks in advance
Yes it is possible. You will get a access token which you can send to the next activity. Use getAccessToken() and setAccessToken().
Here is an example that even saves the needed data: Contact-Picture-Sync
you need to install an extension, similar to the core Android SDK, but no, here is what you need to do:
1.) go to github.com/facebook/facebook-android-sdk
2.) download the facebook directory ONLY! The other directories are only examples.
3.) Put the files from the src (you can copy the drawables too, if you want to) in the package, you are currently working with
4.) You are good to go, you can use the facebook "SDK"
see also this example https://github.com/facebook/facebook-android-sdk/tree/master/examples/Hackbook download it , it is working example provided by facebook
just to provide an alternative answer, there's other ways of implementing sharing on Android.
It allows for more sharing options (like Twitter, QR-Barcodes, blogging and whatnot) without having to deal with the facebook android sdk.
What you would use is a "share" intent, like so:
String title = "My thing"; // used if you share through email or channels that require a headline for the content, always include this or some apps might not parse the content right
String wallPost = "Hey - check out this stuff: http://link.com "; // the content of your wallpost
String shareVia = "Share this stuff via"; // the headline for your chooser, where the phones avaliable sharing mechanisms are offered.
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.setType("text/plain");
shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, title);
shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, wallPost);
startActivity(Intent.createChooser(shareIntent, shareVia));
This is by far the preferred solution on Android if you're looking for simple sharing, as it makes your app future-compatible with new services. And more lean and flexible for the user too, as there's little to no friction from hitting the share button to posting content.
It can also be seen in this blog post: http://android-developers.blogspot.com/2012/02/share-with-intents.html
I hope you can use this for your project.
This is my first question on StackOverflow, and my english is poor, so please :D. I do this just for fun. I want to change the icon per user, letting users change the icon of the app. I think if I want to do this, I must read the apk self, unzip it, change che drawable/icon.png and rebuild it, at last to sign.
I try some code, but failed. The import reason is that, package sun.securate.* is not in Android Java framework. I write some code to do this, but it failed-_-
Who can help me? I can share my already written code.
Help me,Please!
Well another work around will be to create shortcut icon for Home Screen which launches the same Activity as the launcher. With this your launcher icon in drawer will be the actual one but on the home screen you will have different icon. You can also explore the idea of creating shortcut for other apps if you know the package info.
Ref:
For package info here are the doc.
PackageManager pkgMgr = getPackageManager();
For creating short cut here is the snippet (this is just for illustration):
// Setting the intent class ActivityClassToLaunch you need to try PackageManager
Intent i = new Intent(activity, ActivityClass.class);
i.setAction(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_LAUNCHER);
Intent result = new Intent();
result.putExtra(Intent.EXTRA_SHORTCUT_INTENT, i);
result.putExtra(Intent.EXTRA_SHORTCUT_NAME, activity.getString(R.string.app_name));
ShortcutIconResource iconResource = null;
iconResource = ShortcutIconResource.fromContext(activity, R.drawable.new_app_icon);
result.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
result.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
activity.sendBroadcast(result);
If you just want user to change the app icon, why dont you load the icon from the SD card. And the icon that you ship with your package will be there if no icon is specified by user.
Here is the snippet that can help you.
onCreate(...)
setContentView(...);
setFeatureDrawable(Window.FEATURE_LEFT_ICON,
<your_drawable>);
....
}
If this does not work, try calling setFeatureDrawable before setContentView
You cannot change the launcher icon of a signed-and-sealed APK, except through a software upgrade.
