Start Activity from RecycleView Adapter on click

I have an issue starting a new activity from a CardView Adapter, this is the code:

RVAdapter adapter = new RVAdapter(array_restaurants);
recList.setAdapter(adapter);

And after in the adapter. I set an OnClickListener

personName.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v) {
                Context context = v.getContext();
                System.out.println("Context");
                System.out.println(context.toString());
                Intent intent = new Intent(v.getContext(), Restaurante.class);
                v.getContext().startActivity(intent);
            }
        });

When i print the context in the console everything looks fine, but after the aplication stop working. Why?

Thank you very much.

How to connect an intent to a function

I don't see how to specify the function that an intent filter calls or how to get the arguments (data) from that intent.

For instance, say in my AndroidManifest.xml file I have the following:

<intent-filter>
     <action android:name="android.intent.action.VIEW"></action>
     <category android:name="android.intent.category.DEFAULT"></category>
     <category android:name="android.intent.category.BROWSABLE"></category>
     <data android:host="example.com" android:scheme="http"></data>
</intent-filter>

A user goes to http://ift.tt/1HMV2Mh - an app-chooser pops up and the user chooses my app (let's call it MyApp). So what gets called within MyApp and how do I get the arguments, in this case /some-end-point that was called?

How do I specify what block of code this intent refers to ... Do I register it within the Java code or do I specify it in the XML?

Sorry for the basic question but I've been unable to find this after quite literally days of searching and going through the sample code.

List fragment not disappearing

Based on my code whenever I run my app and click a list item, the intended fragment does appear but the list fragment does not disappear from view (see attached screenshot). What needs to be done in order to remove the list from the user's view?

    FragmentItem1 newFragment = new FragmentItem1();
    FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

    transaction.replace(R.id.master_container, newFragment);                         

transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
    transaction.addToBackStack(null);
    transaction.commit();

Unable to get the Contacts in HTC devices

I'm getting contacts from the ContactPicker from various devices but While trying to fetch contact from HTC devices I'm gettting the below exception :

java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.HtcContactsProvider2 uri content://com.android.contacts/data/719 from pid=8344, uid=10214 requires android.permission.READ_CONTACTS, or grantUriPermission()

Permissions that I have given is:

android.permission.READ_CONTACTS

Below is the code that I have implemented:

Intent intent = new Intent(Intent.ACTION_PICK,
                        Phone.CONTENT_URI);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
                startActivityForResult(intent, 101);


@Override
    protected void onActivityResult(int arg0, int arg1, Intent arg2) {
        // TODO Auto-generated method stub
        super.onActivityResult(arg0, arg1, arg2);

        if (arg1 == Activity.RESULT_OK) {
            Uri contactData = arg2.getData();
            ContentResolver cur = getContentResolver();
            Cursor cursorID = getContentResolver().query(contactData,
                    new String[] { ContactsContract.Contacts._ID }, null, null,
                    null);

            grantUriPermission("ContactsContract.CommonDataKinds.Phone.CONTENT_URI", contactData, 2);
            Cursor c = cur.query(contactData, null, null, null, null);
            if (c.moveToFirst()) {
                String name = c
                        .getString(c
                                .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

                String number = c
                        .getString(c
                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                Toast.makeText(getApplicationContext(),
                        "" + name + " " + number, 4000).show();

            }
        }

    }

Any help is appreciated.

Cannot share images to WeChat and Line using ACTION_SEND intent

My code is as below -

 Intent prototype = new Intent(Intent.ACTION_SEND);
 prototype.setData(uri);   // uri is of the image file
 prototype.setType(image/*);
 prototype.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

 prototype.putExtra(Intent.EXTRA_STREAM, uri); 

List<ResolveInfo> resInfo = pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
       if (!resInfo.isEmpty()) 
       { 
           for (ResolveInfo resolveInfo : resInfo) 
            {
                if (resolveInfo.activityInfo == null)  
                {
                    continue; 
                }

                // Retrieve the package name and class name to populate the chooser intent
                Intent intent = (Intent) prototype.clone();
                String packageName = resolveInfo.activityInfo.packageName;
                intent.setPackage(packageName); 
                intent.setClassName(packageName, resolveInfo.activityInfo.name); 
            targetedIntents.add(intent);
        }}
            Intent chooserIntent = Intent.createChooser(topIntents.remove(targetedIntents.size() - 1), chooserTitle); 
                chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toArray(new Parcelable[] {})); 

When I select WeChat and Line app from the chooser, nothing happens. Line app just displays an error that it is unable to share. WeChat doesn't give any message. Sharing works fine on Whatsapp and Hangouts using my code.

We can share images on WeChat and Line from Gallery. How does that work? Is it not a Send action intent?

Qt for Android - startActivityForResult equivalent does not work

There are poorly documented features in Qt for Android - we can use Intent features by JNI (Java Native Interface). There are some examples with startActivity equivalent, but I did not find any with result receiving.

Here's Java code with ilustration what I want to do:

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
getActivity().startActivityForResult(intent, 1);

I used documentation to write equivalent in Qt:

QAndroidJniObject ACTION_GET_CONTENT = QAndroidJniObject::getStaticObjectField<jstring>("android/content/Intent", "ACTION_GET_CONTENT");
QAndroidJniObject intent("android/content/Intent");
if (ACTION_GET_CONTENT.isValid() && intent.isValid()) {
    intent.callObjectMethod("setAction", "(Ljava/lang/string;)V", ACTION_GET_CONTENT.object<jstring>());
    intent.callObjectMethod("setType", "(Ljava/lang/string;)V", QAndroidJniObject::fromString("file/*").object<jstring>());
    QtAndroid::startActivity(intent, EXISTING_FILE_NAME_REQUEST, receiver);
    return true;
} else {
    return false;
}

receiver is a pointer to object of class, which extends abstract class QAndroidActivityResultReceiver. Here's it's implementation of virtual function handleActivityResult:

void MyReceiver::handleActivityResult(int receiverRequestCode, int resultCode, const QAndroidJniObject &data)
{
    jint RESULT_OK = QAndroidJniObject::getStaticField<jint>("android/app/Activity", "RESULT_OK");
    if (receiverRequestCode == EXISTING_FILE_NAME_REQUEST && resultCode == RESULT_OK) {
        QString path = data.callObjectMethod("getData", "()Landroid/net/Uri;").callObjectMethod("getPath", "()Ljava/lang/String;").toString();
        _dialog->emitExistingFileNameReady(path);
    } else {
        _dialog->emitExistingFileNameReady(QString());
    }
}

Something is wrong with my code, because when I run it, following error messages appears (and program is being aborted):
