open-url-in-qt-android

Sample implementation to demonstrate how to launch a QT app on Android by clicking on a link that has a specific schema (pocintent://).

The important parts are:

poc.intent.OpenUrlClient extends QtActivity

• implements onNewIntent(Intent intent) http://developer.android.com/reference/android/app/Activity.html#onNewIntent(android.content.Intent)

• JNI call to the C++ side of QT public static native void setUrl(String url)

C++ implementation openurlclient.cpp

• implementation of the JNI call

    JNIEXPORT void JNICALL
      Java_poc_intent_OpenUrlClient_setUrl(JNIEnv *env, jobject obj, jstring url)
    {
    	const char *urlStr = env->GetStringUTFChars(url, NULL);
    	OpenUrlClient::getInstance()->setUrl(urlStr);
    	env->ReleaseStringUTFChars(url, urlStr);
    	return;
    }
  

AndroidManifest.xml

<activity ... android:name="poc.intent.OpenUrlClient" ... android:launchMode="singleTask">
...
<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="pocintent" android:path="/"/>
</intent-filter>

• android:name pointing to our QtActivity implementation

• launchMode=singleTask as described in http://developer.android.com/reference/android/R.styleable.html#AndroidManifestActivity_launchMode

• <intent-filter> Browsable category (http://developer.android.com/reference/android/content/Intent.html#CATEGORY_BROWSABLE) and our specific schema pocintent://
