How do I get audio input to the android default speech recogniser when it cannot return a result

I have a project that invokes android's default speech recognition system, using RecognizerIntent.ACTION_RECOGNIZE_SPEECH
The UI is 1 textview and 1 command button, to show the result of speech recognition and to start speech recognition, respectively
I also record the input to the speech recogniser in an AMR file using the method shown here:
record/save audio from voice recognition intent
This is possible because the input audio tot he speech recogniser is available as an InputStream in the Intent data returned by the speech recogniser activity
However, I have noticed that when the speech recogniser activity fails to recognise speech (different from incorrect recognition), the onActivityResult(...) function is still called, but it does not return the Intent data, causing NullPointerException when trying to read the AMR file. How do I get the input to the speech recogniser when it fails to recognise speech?

For reference, this is what I mean when I said the speech recogniser fails to recognise speech (Note that this is different from when the speech recogniser detects wrongly; in case of a wrong detection, it is still recognising speech)

Android app + Drive API with full-drive access ... what's the procedure?

I'm looking for some guidance related to accessing Google Drive with an Android app.
1) I need to be able to read files uploaded by users outside of my app. Does this mean I need full-drive access? (If the app could create a folder and then see all files uploaded by the user that exist in this folder, that would be great, but I don't think it works this way.)
2) If I need full-drive access, it seems that Googles "Drive API for Android" doesn't support this, and I need to use the REST api. I think this is true.
3) I need an Auth 2.0 client ID from Google. If I use the rest API, does this mean I need to use a "Web Application" ID? I think I need this because I want an "auth code". I wasn't able to get it working with an "Android" type ID.
4) I'm currently using "Google Sign-In" for Android to handle the login and provide an auth code. I can then convert this into a Token + Refresh Token, and save these so I can get new tokens after an hour in some fashion. Is this manually handling of refresh tokens required?
It's getting ugly, but I think that since I need (?) full-drive access then this is the procedure.
Thanks for any guidance.
Edit: The question has been identified as a duplicate. The link provided gives an answer for question #2, but doesn't address the other questions.
I agree the question is messy...

I'm answering my own question.
I struggled with this because A) Google's REST example uses an outdated login process, B) The "Sign In" example uses code that doesn't work with "full-access" scope, and C) the there were too many vastly different code examples when trying to put it all together.
To quickly answer my questions as I see it now:
1) Yes, full-drive access is required to read files uploaded outside my app.
2) Yes, I need to use REST api.
3) Yes, I need a "Web Application" client ID.
4) Google Sign-In seems the best way currently to sign in, and using a GoogleCredential object along with the Drive api abject will handle the token refreshes automatically, as long as you keep around a refresh token.
In case anyone else is struggling with accessing Drive with full-access from Android using the latest "Sign-In" procedure and REST v3, below is my sample code.
In addition to the "Web application" OAuth client ID, you also need to create an "Android" type ID with a matching package name and certificate fingerprint in order for the Sign-In to work. Also note that you'll have different certificates for your dev and production versions. The IDs/codes from these Android clients do not need to be entered into the app.

The latest example in https://developers.google.com/drive/v3/web/quickstart/android works out of the box.
Just do the following:
1 - Go to Google API console and create an OAuth2 Client ID using your package name and debug/release key as your Signing-certificate fingerprint.
2 - Enable Google Drive API
3 - Apply the following code
build.gradle : app
compile 'com.google.android.gms:play-services-auth:10.0.1'
compile 'pub.devrel:easypermissions:0.2.1'
compile('com.google.api-client:google-api-client-android:1.22.0') {
exclude group: 'org.apache.httpcomponents'
}
compile('com.google.apis:google-api-services-drive:v3-rev57-1.22.0') {
exclude group: 'org.apache.httpcomponents'
}

In this code just change the scope to DriveScopes.DRIVE for full drive access

How to request permissions during run time when using Gluon mobile environment?

I am new here and reason for that I don't know all rules of the site yet, sorry about that!
I am building a Java application to Desktop and Android by using Gluon mobile plugin in Eclipse tool. I have variated code for Desktop and Android as described in an example (http://docs.gluonhq.com/samples/gonative/). So I have Android specific NativeService where I have a method to read files from external storage (that works). I have also studied how to request permissions on run time when using native Android environment (Storage permission error in Marshmallow ). I am able to request the permission, but I can not catch the result.
I am now requesting the permissions same way, but how I can receive the results? I cannot overrrive onRequestPermissionsResult as in the example, becauce I have not directly available android.support.v4.app stuff. Could someone help me and provide an example?
AndroidNativeService.java:

For starters, you can add the android-support-v4.jar to your project:
Copy it from its location under ANDROID_HOME/extras/android/support/v4/android-support-v4.jar to a libs folder in your project, and then add the dependency to the build.gradle file:
dependencies {
androidCompile files('libs/android-support-v4.jar')
}
Assuming you are targeting Android SDK 23+:
android {
minSdkVersion '23'
compileSdkVersion '23'
targetSdkVersion '23'
manifest = 'src/android/AndroidManifest.xml'
}
then you know that by default all the permissions included in the manifest will be disabled.
If you want to check for permissions on runtime, you can define a new activity that takes care of requesting permissions with a built-in dialog (using ActivityCompat.requestPermissions), register this activity in the manifest, and call it from the FXActivity within a new intent that passes a list with the required permissions.
You just need to call FXActivity.getInstance().setOnActivityResultHandler() to listen to the end of that activity and resume the call if permissions were granted.
The following code is partly based in the PermissionHelper class.
I'll use the simple case of the Dialer service from the new Charm Down 3.0.0 library, that requires Manifest.permission.CALL_PHONE.
AndroidDialerService.java, under Android package
public class AndroidDialerAskService implements DialerAskService {
public static final String KEY_PERMISSIONS = "permissions";
public static final String KEY_GRANT_RESULTS = "grantResults";
public static final String KEY_REQUEST_CODE = "requestCode";
#Override
public void call(String number) {
if (Build.VERSION.SDK_INT >= 23) {
if (ContextCompat.checkSelfPermission(FXActivity.getInstance(), Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
FXActivity.getInstance().setOnActivityResultHandler((requestCode, resultCode, data) -> {
if (requestCode == 11112) {
// if now we have permission, resume call
if (ContextCompat.checkSelfPermission(FXActivity.getInstance(), Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
call(number);
}
}
});
Intent permIntent = new Intent(FXActivity.getInstance(), PermissionRequestActivity.class);
permIntent.putExtra(KEY_PERMISSIONS, new String[]{Manifest.permission.CALL_PHONE});
permIntent.putExtra(KEY_REQUEST_CODE, 11111);
FXActivity.getInstance().startActivityForResult(permIntent, 11112);
return;
}
}
if (number != null && !number.isEmpty()) {
Uri uriNumber = Uri.parse("tel:" + number);
Intent dial = new Intent(Intent.ACTION_CALL, uriNumber);
FXActivity.getInstance().startActivity(dial);
}
}
public static class PermissionRequestActivity extends Activity {
private String[] permissions;
private int requestCode;
#Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
FXActivity.getInstance().onRequestPermissionsResult(requestCode, permissions, grantResults);
finish();
}
#Override
protected void onStart() {
super.onStart();
permissions = this.getIntent().getStringArrayExtra(KEY_PERMISSIONS);
requestCode = this.getIntent().getIntExtra(KEY_REQUEST_CODE, 0);
ActivityCompat.requestPermissions(this, permissions, requestCode);
}
}
}

TextToSpeech android build version not playing audio

I have a strange behavior of my text to speech engine on android:
When I test text to speech on my Galaxy S5 everything is fine, audio is playing in turkish and in german.
On some other phones (such as one LG for example) the textToSpeech does work too- except in following case:
Export the app (build apk) and installing it manually on a phone
Switch to Turkish language (German language always works!)
The problem is that I get no error message- the TTS seems to get normally initialized.
Any hint would be really appreciated!
here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getActionBar().setLogo(R.drawable.anne_eli_icons_pfeile_zurueck_weiss_17px);
getActionBar().setHomeButtonEnabled(true);
textToSpeech = new TextToSpeech(this, this);
}
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
log("onInit()");
int result = textToSpeech.setLanguage(new Locale(getTransLanguage()));
log("result:" + result);
textToSpeech.setSpeechRate(1.2f); // set speech speed rate
if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
Tools.showToast(this, "Language " + getTransLanguage() + " is not supported! Error code: " + result);
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
} else {
speechEnabled = true;
}
} else {
speechEnabled = false;
Tools.showToast(this, "Text to speech initialization failed!");
}
}

Before, check if TTS Service is avaliable:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
/**
* This class demonstrates checking for a TTS engine, and if one is

Failure in resolving TextToSpeech class for Android Development

I'm new to Android development, Eclipse and Java (done mostly .Net and IVR programming up till now), so when I tried to compile and run a sample app I found for TTS on the Droid, I wasn't surprised that I got a runtime error right away. The error is:
dalvikvm Failed resolving com/sample/TTSapp/AndroidTTSapp; interface 4 'android/speech/tts/TextToSpeech$OnInitListner;'
I suppose the OnInitListner method must be in one of the classes that was installed when I installed the Android SDK (release 1.6 R1 I believe), but I'm not sure how to import the associated class module into the current program. I can't find a speech/tts/TextToSpeech directory anywhere on my system. Do I need to download this directory from somewhere? Following is the Java source code for the demo TTS program I'm trying to run:

mAgainButton = (Button) findViewById(R.id.again_button);
mAgainButton.setOnClickListener(new View.OnClickListener()
{

{
sayHello();
}
});
}
#Override

if (mTts != null)
{
mTts.stop();
mTts.shutdown();
}
super.onDestroy();
}

public void onInit(int status)
{
// status can be either TextToSpeech.SUCCESS or TextToSpeech.ERROR.
if (status == TextToSpeech.SUCCESS)
{

if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED)
{
// Language data is missing or the language is not supported.
Log.e(TAG, "Language is not available.");
}
else
{
// Check the documentation for other possible result codes. For example, the language may be available for the locale
// but not for the specified country and variant.
// The TTS engine has been successfully initialized. Allow the user to press the button for the app to speak again.
mAgainButton.setEnabled(true);
// Greet the user
sayHello();
}
}
else
{
// Initialization failed.
Log.e(TAG, "Could not initialize TextToSpeech.");
}
};
private static final Random RANDOM = new Random();
private static final String[] HELLOS =
{
"Hello World", "This is Text to speech demo by Zahid Shaikh"
};
private void sayHello()
{
// Select a random hello.
int i =0;
int helloLength = HELLOS.length;
String hello = HELLOS[i];
i++;
if(i == helloLength) i =0;
mTts.speak(hello,TextToSpeech.QUEUE_FLUSH,null);
}
}
Thanks in advance for any assitance anyone can give a beginner like myself.
