TextToSpeech android API 22 not playing audio

I am using text to speech engine in my App. It works fine on emulator Nexus 6 with API 23 and higher. But on emulator Nexus 6 with API 22 it does not speak.
Both emulators use Pico TTS as preferred engine.
My activity layout contains only one button "Speak".
This is my activity code:
public class MainActivity extends AppCompatActivity {
private TextToSpeech mTTS;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button speakBtn = findViewById(R.id.button);
speakBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speak();
}
});
mTTS = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = mTTS.setLanguage(Locale.US);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.e("TTS", "Language not supported");
}
mTTS.setOnUtteranceProgressListener(new UtteranceProgressListener() {
#Override
public void onStart(String utteranceId) {
Log.d("TTS", "onStart called, utteranceId = " + utteranceId);
}
#Override
public void onDone(String utteranceId) {
Log.d("TTS", "onDone called, utteranceId = " + utteranceId);
}
#Override
public void onError(String utteranceId) {
Log.d("TTS", "onError called, utteranceId = " + utteranceId);
}
});
} else {
Log.e("TTS", "Initialization failed");
}
}
});
}
private void speak() {
Log.d("TTS", "speak() method called");
HashMap<String, String> map = new HashMap<>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "greeting");
mTTS.speak("hello", TextToSpeech.QUEUE_FLUSH, map);
}
}

Figured out how to solve the problem. Everything works if launch the emulator not via Debugging or Execution but from AVD Manager after starting Android Studio.

Activity is completely blank when ran - maybe as a result of internet permissions?

I'm fairly new to java/android development so please bear with me.
I've created an app as part of a online course that should supposedly run a "Guess the celebrity game".
The issue is when i run my code the main activity is completely blank.
The strange part is that the app presented in the course runs without issue and i have followed the code word for word. I have managed to find one other candidate who has the same issue and cannot solve it.
There are no errors (that i can find) in the logs and i can't seem to find any posts with a similar issue.
This weird behaviour only occours when i add the following permission in the manifest xml:
<uses-permission android:name="android.permission.INTERNET" />

Any help would be much appreciated, thanks!

You are using the AsyncTask but did not started it. Use execute() method to start your async task.

Back button, jsoup and AsyncTask

Help me, please, I have already searched the whole Internet. Why pressing on Back button close the program, not get on previous page? I think, the reason - there is no history for webview.canGoBack(), but i can't understand, why.. Sorry, if it's stupid question, I'm newbie in programming.
public class MainActivity extends Activity {
WebView webview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
webview = (WebView) findViewById(R.id.webView1);
new ParseMyPageTask()
.execute("https://mysite.com/forumdisplay.php?f=36&styleid=35");
webview.setWebViewClient(new ForumWebViewClient());
}
class ParseMyPageTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... params) {
Document doc = null;
String htmltext = "";
try {
doc = Jsoup.connect(params[0]).get();
Elements body = doc.select("ul.forumbits, ul#stickies, ul#threads, ol#posts");
htmltext = body.html();
} catch (IOException e) {
e.printStackTrace();
}
return htmltext;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
webview.getSettings().setUseWideViewPort(true);
webview.setInitialScale(0);
webview.loadDataWithBaseURL(null, "result", "text/html", "UTF-8", null);
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
webview.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
private class ForumWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
new ParseMyPageTask().execute("https://mysite.com/" + url + "&styleid=35");
return true;
}
}
}
I think it is because of somewhere here:
private class ForumWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
new ParseMyPageTask().execute("https://mysite.com/" + url + "&styleid=35");
return true;
}
}
Result of
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
if (isDebug) {
Log.v(TAG, "BackButton canGoBack. " + event);
}
webview.goBack();
return true;
}
if (isDebug) {
Log.v(TAG, "BackButton pressed. " + event);
}
return super.onKeyDown(keyCode, event);
}

07-29 21:20:54.596: E/webview(9044): removeForStylusPenEvent END
Result of following code the same:
#Override
public void onBackPressed(){
if (webview.canGoBack()) {
webview.goBack();
if (isDebug) {
Log.v(TAG, "goBack");
}
return;
}
if (isDebug) {
Log.v(TAG, "onBackPressed");
}
super.onBackPressed();
}

try this,
#override
public void onBackPressed(){
super.onBackPressed();
if ( webview.canGoBack()) {
webview.goBack();
}
}

you can try this one to close the Activty on back press
#Override
public void onBackPressed() {
super.onBackPressed();
this.finish();
}

Lower version app not running in the Higher version in android

I have made my application using android SDK 2.2 version and now when I am running my app on android SDK 4.0.3 it's not running.
I have given the min and the max sdk in the manifest file.
I am new in android and want to run my app for the lower and higher versions both. Can anybody tell me how can I do this. Any help is appreciated.

The reason why your app is crashing on 4.0.3 but not 2.2 is most likely because you are performing an expensive operation on the UI thread. Blocking the UI thread is very bad practice... don't do it!! Previous versions of Android (i.e. pre-ICS versions) didn't care when you did this and let your app run as is. In 4.0 and above, however, the OS checks against this and crashes your app if you ever perform a potentially expensive operation on the UI thread (such as a network connection, etc.).
You have provided basically no information on what the problem is in your question, so that's all I can really do to help you out.
Edit:
Does something like this work?
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Intent i = new Intent();
i.setClass(sPlashScreen, K_trivia_cricketActivity.class);
startActivity(i);
}
return true;
}

Don't you threads because it is creating the problem in the higher version. Use the code below to show the splash screen.
package com.Cricket_trivia.in;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.MotionEvent;
public class SplashScreen extends Activity {
protected int _splashTime = 5000;
private Thread splashTread;
MyCount counter = new MyCount(4000, 4000);
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
counter.start();
}
public class MyCount extends CountDownTimer
{
public MyCount(long csecond, long countDownInterval)
{
super(csecond, countDownInterval);
}
#Override
public void onFinish() {
finish();
Intent intent = new Intent();
intent.setClass(SplashScreen.this, K_trivia_cricketActivity.class);
startActivity(intent);
}
#Override
public void onTick(long arg0) {
// TODO Auto-generated method stub
}
}
}
I think it will work for you

Android - Large file downloads stop - using async/progressdialog

I have a simple code that is supposed to do one task, when the button is clicked download a file, save it to the SD card, and open it. Everything works except during the download, for larger files, the connection drops and the progress bar hangs - almost always at 20%. I have searched and searched and cannot figure out what to do to keep the connection alive and allow the download to complete. Any ideas how to keep the connection alive so the download completes instead of stalling at 20%?

I've tried to download your file a few times, looks like download stalls for a few seconds here and there, and it might trigger a timeout in your application. Try to specify timeouts explicitly in range 10-20 seconds.
private DefaultHttpClient httpclient = new DefaultHttpClient();
private HttpGet get = new HttpGet("your url comes here");
protected String[] doInBackground(Void... v) {
HttpParams httpParameters = new BasicHttpParams();
// set the timeout in milliseconds until a connection is established
// the default value is zero, that means the timeout is not used
int timeoutConnection = 3000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
// set the default socket timeout (SO_TIMEOUT) in milliseconds
// which is the timeout for waiting for data
int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
httpclient.setParams(httpParameters);
try {
HttpEntity entity = httpclient.execute( get ).getEntity();
FileOutputStream output = new FileOutputStream(outputFile);
entity.writeTo(output);
output.close();
// return something, maybe?
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
httpclient.getConnectionManager().shutdown();
}
return null;
}

What seems to be the problem is that process 199 in your logcat seem to be your activity, but then it shows:
I/ActivityManager( 199): Force stopping package com.viperean.atcassistant uid=10102
I/ActivityManager( 199): Killing proc 20698:com.viperean.atcassistant/10102: force stop
W/ActivityManager( 199): Force removing ActivityRecord{41eb1ec0 com.viperean.atcassistant/.atcChoice}: app died, no saved state
(and the second line shows that it is killing your asynctask...).
I don't think there is anything wrong with the download code by itself. I think you should look more in the activity (what are you doing during that time beside that asynctask, what are you displaying on the screen...etc...).
Seems also that you are pretty low in heap space.

Those are from the garbage collection and happen just before your app crashed, maybe that could be a problem too?

every thread in Android is being killed by the system if it doesn't respond for more than five minutes. maybe you should consider downloading as a service or overriding the onProgress and get the thread to stay alive
