The QtAndroid namespace provides miscellaneous functions to aid Android development.
This enum is used with QtAndroid::bindService to describe the mode in which the binding is performed.
Constant | Value | Description |
---|---|---|
QtAndroid::None |
0x00000000 |
No options. |
QtAndroid::AutoCreate |
0x00000001 |
Automatically creates the service as long as the binding exist. See BIND_AUTO_CREATE documentation for more details. |
QtAndroid::DebugUnbind |
0x00000002 |
Include debugging help for mismatched calls to unbind. See BIND_DEBUG_UNBIND documentation for more details. |
QtAndroid::NotForeground |
0x00000004 |
Don't allow this binding to raise the target service's process to the foreground scheduling priority. See BIND_NOT_FOREGROUND documentation for more details. |
QtAndroid::AboveClient |
0x00000008 |
Indicates that the client application binding to this service considers the service to be more important than the app itself. See BIND_ABOVE_CLIENT documentation for more details. |
QtAndroid::AllowOomManagement |
0x00000010 |
Allow the process hosting the bound service to go through its normal memory management. See BIND_ALLOW_OOM_MANAGEMENT documentation for more details. |
QtAndroid::WaivePriority |
0x00000020 |
Don't impact the scheduling or memory management priority of the target service's hosting process. See BIND_WAIVE_PRIORITY documentation for more details. |
QtAndroid::Important |
0x00000040 |
This service is assigned a higher priority so that it is available to the client when needed. See BIND_IMPORTANT documentation for more details. |
QtAndroid::AdjustWithActivity |
0x00000080 |
If binding from an activity, allow the target service's process importance to be raised based on whether the activity is visible to the user. See BIND_ADJUST_WITH_ACTIVITY documentation for more details. |
QtAndroid::ExternalService |
-2147483648 |
The service being bound is an isolated, external service. See BIND_EXTERNAL_SERVICE documentation for more details. |
This enum was introduced or modified in Qt 5.10.
This enum is used to describe the permission status.
Constant | Value | Description |
---|---|---|
QtAndroid::Granted |
0 |
The permission was granted. |
QtAndroid::Denied |
1 |
The permission was denied. |
This enum was introduced or modified in Qt 5.10.
Synonym for std::function<void(const PermissionResultMap &)>.
Synonym for QHash<QString, PermissionResult>.
Synonym for std::function<void()>.
Returns the Android SDK version. This is also known as the API level.
This function was introduced in Qt 5.3.
Binds the service given by serviceIntent, serviceConnection and flags. The serviceIntent object identifies the service to connect to. The serviceConnection is a listener that receives the information as the service is started and stopped.
Returns true on success
See Android documentation documentation for more details.
This function was introduced in Qt 5.10.
See also QAndroidIntent, QAndroidServiceConnection, and BindFlag.
Hides the splash screen immediately.
This function was introduced in Qt 5.7.
Hides the splash screen, fading it for duration milliseconds.
This function was introduced in Qt 5.10.
Asynchronously requests permissions to be granted to this application, callbackFunc will be called with the results.
This function was introduced in Qt 5.10.
Posts the given runnable on the android thread. The runnable will be queued and executed on the Android UI thread, unless it called on the Android UI thread, in which case the runnable will be executed immediately.
This function is useful to set asynchronously properties of objects that must be set on on Android UI thread.
This function was introduced in Qt 5.7.
Posts the runnable on the Android UI thread and waits until the runnable is executed, or until timeoutMs has passed
This function is useful to create objects, or get properties on Android UI thread:
QAndroidJniObject javaControl; QtAndroid::runOnAndroidThreadSync([&javaControl](){ // create our Java control on Android UI thread. javaControl = QAndroidJniObject("android/webkit/WebView", "(Landroid/content/Context;)V", QtAndroid::androidActivity().object<jobject>()); javaControl.callMethod<void>("setWebViewClient", "(Landroid/webkit/WebViewClient;)V", QAndroidJniObject("android/webkit/WebViewClient").object()); }); // Continue the execution normally qDebug() << javaControl.isValid();
This function was introduced in Qt 5.7.
Returns true
if you should show UI with a rationale for requesting a permission.
This function was introduced in Qt 5.10.
Starts the activity given by intent and provides the result asynchronously through the resultReceiver if this is non-null.
If resultReceiver is null, then the startActivity()
method in the androidActivity()
will be called. Otherwise startActivityForResult()
will be called.
The receiverRequestCode is a request code unique to the resultReceiver, and will be returned along with the result, making it possible to use the same receiver for more than one intent.
This function was introduced in Qt 5.3.
Starts the activity given by intentSender and provides the result asynchronously through the resultReceiver if this is non-null.
If resultReceiver is null, then the startIntentSender()
method in the androidActivity()
will be called. Otherwise startIntentSenderForResult()
will be called.
The receiverRequestCode is a request code unique to the resultReceiver, and will be returned along with the result, making it possible to use the same receiver for more than one intent.
This function was introduced in Qt 5.3.
