QtAndroidAPI

What can do

This is a library for easily calling Android methods in Qt.

To display a Toast in traditional Qt, you need the following code:

QJniObject javaString = QJniObject::fromString("Message");
QJniObject toast = QJniObject::callStaticObjectMethod("android/widget/Toast", "makeText",
                                                      "(Landroid/content/Context;Ljava/lang/CharSequence;I)Landroid/widget/Toast;",
                                                      QNativeInterface::QAndroidApplication::context().object(),
                                                      javaString.object(),
                                                      jint(0));
toast.callMethod<void>("show");

When using this library, just:

#define QT_ANDROID_API_AUTOUSE
#include <AndroidContext>
#include <android/widget/Toast>
auto toast = Toast::makeText(CONTEXT, QStringLiteral("Message"), 0);
toast.show();

How to use

Add the following to your CMake:

include(FetchContent)
FetchContent_Declare(androidapi
    GIT_REPOSITORY https://github.com/YJBeetle/QtAndroidAPI.git
    GIT_TAG origin/Qt6
    SOURCE_SUBDIR android-31
)
FetchContent_MakeAvailable(androidapi)

And add the link library after your target

target_link_libraries(${PROJECT_NAME} PRIVATE QtAndroidAPI)
