android自定义intent,Qt / QML Android最佳实践发送自定义Intent(共享URL)

使用其他静态方法扩展QtActivity：

package org.whatever

public class YourActivity extends org.qtproject.qt5.android.bindings.QtActivity

{

private static YourActivity instance;

YourActivity() {

instance = this;

}

public static void shareUrl(QString url) {

//create intent here

//can use instance object

}

}

在c方面使用QAndroidJniObject调用shareUrl方法

class QmlInterface : public QObject

{

Q_OBJECT

public:

QmlInterface();

Q_INVOKABLE void shareUrl( QString url );

};

和实施：

void QmlInterface:: shareUrl( QString url )

{

#ifdef Q_OS_ANDROID

QAndroidJniObject::callStaticMethod( "org/whatever/YourActivity","shareUrl","(Ljava/lang/String;)V",QAndroidJniObject::fromString( url ));

#endif

}

在java端使用静态方法可以显着简化jni调用,因为您不必获取Activity实例.因为需要Activity上下文来发送Intent,所以在java端使用静态实例成员对象.
