How to start and App Chooser

The task of this application is to implicitly activate a separate application to view the URL, “http:// www.google.com”. So, App Chooser should appear and let me choose between at least two browsers: the default one, which will show me the www.google.com site, and another simple "browser", which just shows me the url. The problem is - App chooser doesn't appear, when i use implicit activity. Probably I wrote wrong intent filters for second "simple browser".

private void startImplicitActivation() {

    Log.i(TAG, "Entered startImplicitActivation()");

    // TODO - Create a base intent for viewing a URL 
    // (HINT:  second parameter uses parse() from the Uri class)
    Uri adress = Uri.parse(URL);
    Intent intentUrlView = new Intent(Intent.ACTION_VIEW, adress);

    // TODO - Create a chooser intent, for choosing which Activity
    // will carry out the baseIntent. Store the Intent in the 
    // chooserIntent variable below. HINT: using the Intent class' 
    // createChooser())
    Intent chooserIntent = Intent.createChooser(intentUrlView, CHOOSER_TEXT);
    //chooserIntent = null;

    Log.i(TAG,"Chooser Intent Action:" + chooserIntent.getAction());
    // TODO - Start the chooser Activity, using the chooser intent
    if (intentUrlView.resolveActivity(getPackageManager()) != null) {
        startActivity(chooserIntent);
    }
}

MANIFEST

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="course.labs.intentslab.mybrowser"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="13"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MyBrowserActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <!-- TODO - Add necessary intent filter information so that this
                            Activity will accept Intents with the 
                            action "android.intent.action.VIEW" and with an "http" 
                            schemed URL -->
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="http" />
        <category android:name="android.intent.category.BROWSABLE" />
        </activity>
    </application>

Easy implementation of multiple actions app chooser:

Intent phoneCall = new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", contactNumber, null));
// Intent sms = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + contactNumber));
Intent whatsapp = new Intent(Intent.ACTION_SENDTO, Uri.parse("smsto:" + contactNumber));
Uri.Builder builder = CalendarContract.CONTENT_URI.buildUpon();
builder.appendPath("time");
ContentUris.appendId(builder, Calendar.getInstance().getTimeInMillis());
Intent calendarIntent = new Intent(Intent.ACTION_VIEW).setData(builder.build());

Intent chooser = Intent.createChooser(whatsapp, "chooser??"); // default action
chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[]{phoneCall, calendarIntent}); // additional actions
startActivity(chooser);

You have to run lab3a_MyBrowser before you run lab3a_IntentsLab, so that the browser gets installed on your phone. Then it will be visible to your chooser.

Seems like the Adam Porter's Third Week Assignment of Programming mobile Application for Android HandHeld systems. Anyway, I hope you have your solution inside the AndroidManifest.xml you would need to add three more intent filters.

<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:scheme="http" />

Further, if you were not able to run the AndroidUnit tests,

make sure you have done something similar to this in the ActionListener of the implicit button call.

Intent baseIntent = new Intent(Intent.ACTION_VIEW);
        baseIntent.setData(Uri.parse(URL));

Intent chooserIntent = Intent.createChooser(baseIntent, "Select Application");

Coursera already has a mailing list. Please use that.

Seriously, you have a GUI editor for manifest.

This

<action android:name="android.intent.action.VIEW" />
<data android:scheme="http" />
<category android:name="android.intent.category.BROWSABLE" />

should placed in <intent-filter> tag, as you already can see in your manifest. Like this:

<activity
    android:name=".MyBrowserActivity"
    android:label="@string/app_name" >

    <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

        <!-- TODO - Add necessary intent filter information so that this
                        Activity will accept Intents with the 
                        action "android.intent.action.VIEW" and with an "http" 
                        schemed URL -->
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <data android:scheme="http" />
        <category android:name="android.intent.category.BROWSABLE" />
    </intent-filter>

</activity>

That is how it done in default browser:

        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="http" />
            <data android:scheme="https" />
            <data android:scheme="about" />
            <data android:scheme="javascript" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.BROWSABLE" />
            <category android:name="android.intent.category.DEFAULT" />
            <data android:scheme="http" />
            <data android:scheme="https" />
            <data android:scheme="inline" />
            <data android:scheme="file" />
            <data android:mimeType="text/html" />
            <data android:mimeType="text/plain" />
            <data android:mimeType="application/xhtml+xml" />
            <data android:mimeType="application/vnd.wap.xhtml+xml" />
        </intent-filter>

Here's how I am doing:

Step 1: First in the strings, 

<string name="webklink">&lt;a href="http://www.google.com">SomeLink&lt;/a></string>

Step 2: My Layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="@string/webklink"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

Step 3: Getting the link from the strings.

public class OpenWeb extends Activity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webopen);

        TextView someLink = (TextView)findViewById(R.id.textView1);
        if(someLink!=null){

            someLink.setMovementMethod(LinkMovementMethod.getInstance());
            someLink.setText(Html.fromHtml(getResources().getString(R.string.webklink)));
        }

    }
}

Hope this helps..:)
