I want to send data from one application A to other application B using AIDL file. My appl A is like below,
public class LibValue {
public static native int intFromJNI(int n);
static {
System.loadLibrary("hello");
System.out.println("LibValue : Loading library");
}
I am getting value from JNI file to above class. The data from above class to send another app B using AIDL service is like below.
IEventService.aidl
interface IEventService {
int intFromJNI(in int n);
}
for this I written IEventImpl.java class
public class IEventImpl extends IEventService.Stub{
int result;
#Override
public int intFromJNI(int n) throws RemoteException {
// TODO Auto-generated method stub
System.out.println("IEventImpl"+LibValue.intFromJNI(n));
return LibValue.intFromJNI(n);
}
}
To access above class I writtn service class like below
public class EventService extends Service {
public IEventImpl iservice;
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
Log.i("EventService", "indside onBind");
return this.iservice;
}
#Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
this.iservice = new IEventImpl();
Log.i("EventService", "indside OncREATE");
}
#Override
public boolean onUnbind(Intent intent) {
// TODO Auto-generated method stub
return super.onUnbind(intent);
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
this.iservice = null;
super.onDestroy();
}
All above classes are server side. The below class is Client(app) class to access data.
public class EventClient extends Activity implements OnClickListener, ServiceConnection{
public IEventService myService;
private Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_event_client);
button = (Button)findViewById(R.id.button1);
this.button.setOnClickListener(this);
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
if (!super.bindService(new Intent(IEventService.class.getName()),
this, BIND_AUTO_CREATE)) {
Log.w("EventClient", "Failed to bind to service");
System.out.println("inside on resume");
}
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
super.unbindService(this);
}
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
this.myService = IEventService.Stub.asInterface(service);
Log.i("EventClient", "ServiceConnected");
}
#Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
Log.d("EventClient", "onServiceDisconnected()'ed to " + name);
// our IFibonacciService service is no longer connected
this.myService = null;
}
I am trying to access data from service class but not able to find out the way. can anybody tell how to access data from service to client application ?
Thanks

I have a class that extends Activity, When I try to access the context from the onCreate() method it gets printed but when I save it in a variable context and try to access it from the committext() function as shown below, It prints null. I also tried using "this" and getBaseContext() directly from the committext() function as it is a part of the same class, I get null pointer exception. Please help me figure out what is going wrong.
public class MainKeyboardActionListener extends Activity implements KeyboardView.OnKeyboardActionListener, View.OnTouchListener {
private Context context;
public static boolean active = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mode_keyboard, false);
context=getBaseContext();
System.out.println("contexxtt1"+context);
}
#Override
public void onStart() {
super.onStart();
active = true;
}
#Override
protected void onResume() {
super.onResume();
}
private static class myHandler extends Handler {
}
;
public void setInputConnection(InputConnection ic) {
}
#Override
public void onKey(int arg0, int[] arg1) {
// TODO Auto-generated method stub
}
#Override
public void onPress(int keyCode) {
}
#Override
public void onRelease(int keyCode) {
commitText(String.valueOf(keyCode));
}
private void handleException(int keyCode) {
}
private void removeHalantMode() {
}
private void commitText(String text) {
if(active==true) {
System.out.println("contexxtt"+context);
}
}
#Override

#Override

}
#Override

super.onPause();
}
#Override

super.onStop();
active = false;
}

Make your myHandler class not static.
I am trying to show flurry interstitial but getting following message in debug screen and I am not receiving interstitial on my screen.

I have followed this tutorial completely :

At present I am working on AndEngine. As error replying I put my all code in UI thread but result is same.
Here is my code for displaying ads :
protected void onCreate(Bundle pSavedInstanceState) {
super.onCreate(pSavedInstanceState);
// configure Flurry
FlurryAgent.setLogEnabled(false);
// init Flurry
FlurryAgent.init(MainGameActivity.this, MY_FLURRY_APIKEY);
mFlurryAdInterstitial = new FlurryAdInterstitial(MainGameActivity.this,
MY_ADSPACE_NAME);
FlurryAdTargeting adTargeting = new FlurryAdTargeting();
// enable test mode for this interstitial ad unit
adTargeting.setEnableTestAds(true);
mFlurryAdInterstitial.setTargeting(adTargeting);
// allow us to get callbacks for ad events
mFlurryAdInterstitial.setListener(interstitialAdListener);
mFlurryAdInterstitial.fetchAd();
}
FlurryAdInterstitialListener interstitialAdListener = new FlurryAdInterstitialListener() {
#Override
public void onFetched(final FlurryAdInterstitial adInterstitial) {
adInterstitial.displayAd();
}
#Override

So what can I do in this situation?
I was wondering, how can I keep the device listening for voice commands with voice recognition while the device is asleep? The idea I have is that I would like the device to respond to my voice, even if I have the screen locked or the screen has timed out.
Is this possible? I have tried using this as a service and an interface and it stops listening once the screen locks. Can I receive any help with this? This is my class.
public class VoiceEngineService extends Activity {
private boolean isSpeakingDone = false; // default setting
private SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer(this);
private AudioManager mAudioManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.wait_for_speech);
// mute beep sound
mAudioManager.setStreamSolo(AudioManager.STREAM_VOICE_CALL, true);
sr.setRecognitionListener(new listener());
Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); // LANGUAGE_MODEL_WEB_SEARCH
i.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication()
.getClass().getName());
i.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 6);
i.putExtra(RecognizerIntent.EXTRA_PROMPT, "");
i.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 5500);
sr.startListening(i);
}
class listener implements RecognitionListener {
#Override
public void onReadyForSpeech(Bundle params) {
// TODO Auto-generated method stub
}
#Override
public void onBeginningOfSpeech() {
// TODO Auto-generated method stub
}
#Override
public void onRmsChanged(float rmsdB) {
// TODO Auto-generated method stub
}
#Override
public void onBufferReceived(byte[] buffer) {
// TODO Auto-generated method stub
}
#Override
public void onEndOfSpeech() {
// TODO Auto-generated method stub
}
#Override
public void onError(int error) {
// TODO Auto-generated method stub
if (SharedPref.getVoiceController() == false) {
sr.cancel();
Intent i = new Intent();
sr.startListening(i);
} else {
sr.stopListening();
sr.destroy();
finish();
}
}
#Override
public void onResults(Bundle results) {
// TODO Auto-generated method stub
isSpeakingDone = true;
ArrayList<String> mDataList = results
.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
Intent i = new Intent();
i.putStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS, mDataList);
setResult(RESULT_OK, i);
finish();
}
#Override
public void onPartialResults(Bundle partialResults) {
// TODO Auto-generated method stub
}
#Override
public void onEvent(int eventType, Bundle params) {
// TODO Auto-generated method stub
}
} // end listener class
#Override
protected void onPause() {
if ((isSpeakingDone == false)) {
finish();
}
super.onPause();
}
#Override
protected void onStop() {
// when speaking is true finish() has already been called
if (isSpeakingDone == false) {
finish();
}
super.onStop();
}
#Override
protected void onDestroy() {
sr.stopListening();
sr.destroy();
super.onDestroy();
}
}
You have to implement your voice listener in a service. Create a class that extends 'Service' and make up some logic to take care of recording.
If you tried already the service, then it might be that you tried to redirect commands to an activity which most likely has been stopped by Android OS. Generally when talking about doing stuff when phone is in lock mode, you only can hope to accomplish tasks in one or more services coupled togethe.
When you are in Activity, of course wen the activity goes out of scope it will be shut down by Android OS. but services can still run in background unless shut dow mm explicitly by your own code or in rare cases that Android will recognize that it needs memory and processor power for other tasks.
Now I'm creating an Android application witch use YouTube api to play Video.
But the player stop when I change Activity.
I want to keep Playing like a Music Player even when Activity will change.
I try to solve that by adding Static on YouTubePlayer.(But cannot solve.)
I mean I want to Keep it's playing when the Activity or the Application itself move to Background.
So if you have any ideas, please share with me :)
-----------------Code-----------------
public class PlayActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener,YouTubePlayer.PlayerStateChangeListener{
public static final String DEVELOPER_KEY = "My_Dev_Key";
private LinearLayout yPos;
private static YouTubePlayer yt;
private YouTubePlayerView ytp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.play);
yPos = (LinearLayout)findViewById(R.id.youtube_pos);
try{
ytp = new YouTubePlayerView(this);
ytp.initialize(DEVELOPER_KEY, this);
}catch(Exception e){
finish();
}
yPos.addView(ytp);
}
#Override
public void onAdStarted() {
// TODO Auto-generated method stub
}
#Override
public void onError(ErrorReason arg0) {
// TODO Auto-generated method stub
}
#Override
public void onLoaded(String arg0) {
// TODO Auto-generated method stub
}
#Override
public void onLoading() {
// TODO Auto-generated method stub
}
#Override
public void onVideoEnded() {
// TODO Auto-generated method stub
}
#Override
public void onVideoStarted() {
// TODO Auto-generated method stub
}
#Override
public void onInitializationFailure(Provider arg0,
YouTubeInitializationResult arg1) {
// TODO Auto-generated method stub
}
#Override
public void onInitializationSuccess(Provider arg0, YouTubePlayer arg1,
boolean arg2) {
// TODO Auto-generated method stub
if(!arg2){
if(yt == null){
yt = arg1;
yt.setPlayerStateChangeListener(this);
yt.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
yt.loadVideo("u0v5A6cQOhs");
}
}
}

I have a class that extends the AsyncTask.
When the doing background task done, in post executed i get the static properties of other class to equal the result of doing background, n I WANT TO BROADCAST IT OUT SO THAT the on receiver in other class will be update interface
here the code of the onPostExecuted
protected void onPostExecute(String result) {
Log.d(tag, "post executed "+result);
// do sth here
if (result != null){
result = result.trim();
String temp_result[];
if ( result.contains("|") ){
temp_result = result.split("\\|");
MyGPS.location_info = temp_result[1];//
Log.d(result, "contains | : "+MyGPS.location_info);
}else if (result.equalsIgnoreCase("300 OK")){
Log.d(result, "in 300 OK BUT UNKNOWN : "+ result);
MyGPS.location_info = "Unknown";
}else if (result.equalsIgnoreCase("400 ERROR"))
Log.d(result, "400 ERROR : "+ result);
else Log.d(result, "else : "+ result);
//assemble data bundle to be broadcasted
//myFilteredResponseThread = new Intent(GPS_FILTER);
myFilteredResponseThread.putExtra("location_info_post",
MyGPS.location_info);
// CAN"T USE SEND BROADCAST METHOD ?
//myFilteredResponseThread.
//Log.e(">>GPS_Service<<", "location_info"+MyGPS.location_info);
}
}
after that i can't write sendBroadcast method , it is undefined whY?
If I understood u correctly following is the solution.
class MyService extends Service{
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
class GPSListener implements LocationListener{
public void onLocationChanged(Location arg0) {
// TODO Auto-generated method stub
// you can get context as follow
MyService.this.getBaseContext().sendBroadcast(new Intent("Hi"));
}
public void onProviderDisabled(String arg0) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String arg0) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
// TODO Auto-generated method stub
}
}
}
}
