URL scheme not working in android browser

Question

I need my application opens when clicking on a link. for this I read that I must use a URL scheme. The link must have the form myapp://parameters.

I read every post on this subject, but when I send an email with "myapp://addUser/?id=22" and I open from chrome (on my phone), it is not clickable.

My manifest:

 <activity
            android:name="com.example.SplashActivity"
            android:label="@string/app_name"
            android:screenOrientation="portrait" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <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="myapp" android:host="com.example"/>
            </intent-filter>

        </activity>

My class:

public class SplashActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_splash);
    Intent intent = getIntent();

    if (Intent.ACTION_VIEW.equals(intent.getAction())) {
        Uri uri = intent.getData();
        String id = uri.getQueryParameter("id"); 
    }

}

Content of the mail to test the code:

myapp://addUser/?id=22

UPDATE

I think the problem is the mail body, but I don't know how I can test this.

Answer 1

In your manifest

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

you define android:host="com.example", so you should modify link URL :

myapp://addUser/?id=22       //error
myapp://com.example/?id=22   //correct

then it can work!!

Answer 2

I made a test here and in the manifest file I just removed the "android:host" parameter, leaving this:

<action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="myapp" />
</intent-filter>

and it opened an URL myapp://testing here that I put on a simple HTML file just for trying.
