'Google Now' Voice Search in Android App

I'm not even sure if this is the right thing to do any more with Google not supporting 'Google Now', but I can't seem to find any suitable alternative.
Using this https://antonioleiva.com/voice_search_google_now/#comment-8611 as a guide I am trying o implement a voice search in my App, but not having much luck.
I already have a search facility for users. What I have done so far:-
GlobalApplication.java
public static Queries getQueriesInstance(Context context) {
if(q == null) {
dbHelper = new DbHelper(context);
q = new Queries(db, dbHelper);
}
return q;
}
Then in MainActivity.java
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
Intent i;
int id = item.getItemId();
...
...
if(id == R.id.nav_search) {
i = new Intent(this, SearchActivity.class);
startActivity(i);
}
...
...
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
And finally, before adding anything, my SearchActivity.java file

Taken from the tutorial link above, I then added the following to my Manifest
AndroidManifest.xml
<activity
android:name="com.projects.activities.SearchActivity">
<intent-filter>
<action android:name="com.google.android.gms.actions.SEARCH_ACTION" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
I then added the following to my SearchActivity.java file
private static final String ACTION_VOICE_SEARCH =
"com.google.android.gms.actions.SEARCH_ACTION";
private void handleVoiceSearch(Intent intent) {
if (intent != null && ACTION_VOICE_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
setSearchViewVisible(true);
searchView.setQuery(query, true);
}
}
The in various places and in slightly different ways, I have tried adding
handleVoiceSearch(getIntent());
to the SearchActivity.java file, but I don't seem to be having much luck. I am testing from an Alpha version uploaded to Play Store.
Is there anything obvious anyone can see I am missing?
Thanks

Clear Cache of All Apps in Marshmallow?

I try to solve using below code:
[Reference: Android: Clear Cache of All Apps?
PackageManager pm = getPackageManager();
// Get all methods on the PackageManager
Method[] methods = pm.getClass().getDeclaredMethods();
for (Method m : methods) {
if (m.getName().equals("freeStorage")) {
// Found the method I want to use
try {
long desiredFreeStorage = 8 * 1024 * 1024 * 1024; // Request for 8GB of free space
m.invoke(pm, desiredFreeStorage , null);
} catch (Exception e) {
// Method invocation failed. Could be a permission problem
}
break;
}
}
and add permission in AndroidMenifest.xml file
<uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>
But when i run this code, then throw exception :
java.lang.IllegalArgumentException: Wrong number of arguments; expected 3, got 2
Any suggestion to overcome this exception or another solution for clear cache of all apps programmatically. Thanks

follow the link. hopefully get a solutions

It looks like there is an additional freeStorage() method added in Android 6 (Marshmallow) that takes an additional volumeUuid parameter:
public void freeStorage(long freeStorageSize, IntentSender pi)
public abstract void freeStorage(String volumeUuid, long freeStorageSize,
IntentSender pi)
Obviously, the new method is showing up first in the returned list of declared methods.
To get around this, you can alter the orginal code so that it looks like this:
PackageManager pm = getPackageManager();
// Get all methods on the PackageManager
Method[] methods = pm.getClass().getDeclaredMethods();
for (Method m : methods) {
if (m.getName().equals("freeStorage")) {
Class[] params = m.getParameterTypes();
if (params.length == 2) {
// Found the method I want to use
try {
long desiredFreeStorage = 8 * 1024 * 1024 * 1024; // Request for 8GB of free space
m.invoke(pm, desiredFreeStorage , null);
} catch (Exception e) {
// Method invocation failed. Could be a permission problem
}
break;
}
}
}

Now there is lots of update in Cordova, they also update there CordovaWebView code. After updating Cordova Android version from 2.7 to 5.1.0, app is crashed. I tried to use SystemWebView instead of CordovaWebView but still get error and crashes as some of methods are missing in SystemWebView.
Please help how can I update previous WebView code or create new multiple WebView in Cordova 5.1.0.
Thanks!!

This is how I implemented new Cordova library in my existing project.
public class MyWebViewFragment extends Fragment{
private Activity mActivity;
private SystemWebView syswvPhoneWebview;
private CordovaWebView wvPhoneWebview;
#Override
public void onAttach(Context context) {
super.onAttach(context);
mActivity = (Activity) context;
}
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
if (mView == null) {
mView = inflater.inflate(R.layout.fragment_web_view, null);
setLayoutViews(mView);
}
return mView;
}
private void setLayoutViews(View mView) {
syswvPhoneWebview = (SystemWebView) mView.findViewById(R.id.wvPhoneWebview);
wvPhoneWebview = new CordovaWebViewImpl(new SystemWebViewEngine(syswvPhoneWebview));
wvPhoneWebview.init((CordovaInterface) getParentFragment(), parser.getPluginEntries(), parser.getPreferences());
syswvPhoneWebview.setWebContentsDebuggingEnabled(true);
syswvPhoneWebview.getSettings().setLoadsImagesAutomatically(true);
syswvPhoneWebview.getSettings().setJavaScriptEnabled(true);
syswvPhoneWebview.getSettings().setDomStorageEnabled(true);
syswvPhoneWebview.getSettings().setBuiltInZoomControls(true);
syswvPhoneWebview.getSettings().setSupportZoom(true);
wvPhoneWebview.loadUrl("www.google.com");
SystemWebViewEngine systemWebViewEngine = (SystemWebViewEngine) wvPhoneWebview.getEngine();
syswvPhoneWebview.setWebViewClient(new DocumentViewClient(systemWebViewEngine, mActivity));
}
}
now webviewclient code.
public class DocumentViewClient extends SystemWebViewClient {
private final Activity activity;
public DocumentViewClient(SystemWebViewEngine parentEngine, Activity activity) {
super(parentEngine);
this.activity = activity;
}
}

why onInterceptTouchEvent overrides the all touch event

I think onInterceptTouchEvent intercept them.
Well, you are returning true from onInterceptTouchEvent(), which means, that as a ViewGroup you do not want any touch event to be passed to children, instead pass that touch event to onTouchEvent().
You should listen for event in onInterceptTouchEvent() return false until you see that this is such a gesture, that shouldn't be handled by children. And on that point only you should return true.

onClick is not called in my viewpager

Now when i click it identified by the onInterceptTouchEvent in the ViewPagerWithTapGestreDetection class.So i need to view a Horizontal scrollbar when i click.Is it the correct way to call it inside onInterceptTouchEvent ?
