I can check to see if the burn-in protection property is enabled, but is there a way to tell when burn-in mode is currently active? Like specifically when the screen shifts.
Basically something like "onAmbientModeChanged" for burn in.
Thanks!
In an activity, extend WearableActivity and override onEnterAmbientMode, you have in parameter a Bundle where you can retrieve the property wanted.
(check this WearableActivity)
#Override
public void onEnterAmbient(Bundle ambientDetails) {
super.onEnterAmbient(ambientDetails);
boolean burnIn = ambientDetails.getBoolean(EXTRA_BURN_IN_PROTECTION);
boolean lowBit = ambientDetails.getBoolean(EXTRA_LOWBIT_AMBIENT);
}
In a CanvasWatchFaceService.Engine, override onPropertiesChanged :
#Override
public void onPropertiesChanged(Bundle properties) {
super.onPropertiesChanged(properties);
boolean lowBit = properties.getBoolean(PROPERTY_LOW_BIT_AMBIENT, false);
boolean burnIn = properties.getBoolean(PROPERTY_BURN_IN_PROTECTION, false);
}
Override onAmbientModeChanged(boolean inAMbientMode), it is called whenever the watchface switches from interactive to ambient mode and vice versa :
#Override
public void onAmbientModeChanged(boolean inAmbientMode) {
super.onAmbientModeChanged(inAmbientMode);
if (mState.isAmbient() != inAmbientMode) {
mState.setAmbient(inAmbientMode);
//make your updates on your drawing parameters if needed
invalidate();
}
}

I want to implement kiosk mode on react native (android). I have implemented the functionality to pin/unpin application and check if lock task mode is active using activityManager.getLockTaskModeState, startLockTask & stopLockTask.
The problem is i cannot track when user unpin the app by pressing recencts/back buttons.
i tried to add event listener with following code without success
public void registerLifecycleEventObserver() {
UiThreadUtil.runOnUiThread(new Runnable() {
#Override
public void run() {
AppCompatActivity activity = (AppCompatActivity) reactContext.getCurrentActivity();
activity.getLifecycle().addObserver(KioskModeModule.this);
}
});
}
#Override
public void onStateChanged(#NonNull LifecycleOwner source, #NonNull Lifecycle.Event event) {
boolean isKioskEnabled = isLockTaskModeActive();
if (this.isKioskEnabled != isKioskEnabled) {
this.isKioskEnabled = isKioskEnabled;
WritableMap args = Arguments.createMap();
args.putBoolean("isKioskEnabled", isKioskEnabled);
sendEvent("onKioskStateChange", args);
}
}
Any idea on how i can listen to kiosk mode state change?
I am trying to build an accessibility service for android and when I am trying to call this function, it always returns 0
class AccessibilityPerform extends Accessibility Service{
#Override
protected void onServiceConnected() {
accessibilityButtonController = getAccessibilityButtonController();
mIsAccessibilityButtonAvailable = accessibilityButtonController.isAccessibilityButtonAvailable();
if (!mIsAccessibilityButtonAvailable) {
return;
}
AccessibilityServiceInfo serviceInfo = getServiceInfo();
serviceInfo.flags |= AccessibilityServiceInfo.FLAG_REQUEST_ACCESSIBILITY_BUTTON;
setServiceInfo(serviceInfo);
}
#Override
public void onAccessibilityEvent(AccessibilityEvent accessibilityEvent) {
Log.d("Action",String.valueOf(accessibilityEvent.getAction()));
}
#Override
public void onInterrupt() {}
}
Also I am having minimumSdk version 28 so no problem with FLAG_REQUEST_ACCESSIBILITY_VERSION and I have also set my xml file properly and all flags have been added. So my question is, Is this normal for an accessibilityEvent.getAction() to return 0 everytime. Because I think that it stands for the action which has been performed like AccessbilityNodeInfo.ACTION_CLICK.
Correct me if I am wrong.
Thanks
Unable to override Here SDK to disable sound effect on the onSpeedExceeded event.
Using the Here Developer tutorial, (https://developer.here.com/blog/android-premium-sdk-speed-limit-warning-example), I succeeded in running the sample app. But...
While driving, when I exceed the speed limit, there is a doot doot doot. I want to override this behaviour as I intend to use my own sounds.
I guessed that I might override the code by creating a NavigationManager.SpeedWarningListener. Unfortunately I can not disable or defeat the 'onSpeedExceeded' sound effects.
NavigationManager.SpeedWarningListener speedWarningListener = new NavigationManager.SpeedWarningListener() {
#Override
public void onSpeedExceeded(String s, float v) {
//super.onSpeedExceeded(s, v);
//Log.v(Global.TAG, "onSpeedExceeded");
Global.SpeedLimitExceeded = true;
}
#Override
public void onSpeedExceededEnd(String s, float v) {
//super.onSpeedExceededEnd(s, v);
//Log.v(Global.TAG, "onSpeedExceededEnd");
Global.SpeedLimitExceeded = false;
}
};
EDITED ANSWER: This method needs to be amended to stop the speed warning:
private void startNavigationManager() {
NavigationManager.Error navError = NavigationManager.getInstance().startTracking();
// added by suggestion from stackoverflow
NavigationManager.getInstance().stopSpeedWarning();
if (navError != NavigationManager.Error.NONE) {
Log.d(Global.TAG, "NavigationManager: false");
//handle error navError.toString());
} else {
//Log.d(Global.TAG, "NavigationManager: true");
}
}
Please set speedWarningEnabled accordingly for NMANavigationManager
navigationManager:didUpdateSpeedingStatus:forCurrentSpeed:speedLimit: will be sent to the delegate when speeding is detected or when a correction is made.

Ideally more information regarding the error would be best i.e the opencv library version etc. Given it seems to be an Android issue, I would advise
File and issue or view issues pertaining to this error on their github page. Search for related Android errors to see if they match.
IF you cannot find a related error, file an issue there.
<CC.CustomEditText
android:id="#+id/receptionIdentityArticle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:theme="#style/ExtendProTheme"
android:maxLength="20"
style="#style/ExtendProTheme.EditText"
android:layout_below="#+id/suppliersSearchInputLabel"
local:MvxBind=" Text ArticleSearchClause, Mode=TwoWay; EnterCommand SearchArticlesCommand; Error Errors['ArticleSearchClause']; Click OnSearchClickCommand" />
So i have a CustomEdit that is different from EditText by overriding two events
this.KeyPress += OnEnterKeyPressed;
this.FocusChange += OnFocusChange;
My problem is that Click command is triggered only second time i click on the EditText. First time it just gets focused then then i click it the second time the Click command triggers. I guess it's how it should work, but i would like to catch the first click it's done on the EditText. An other event maybe it is triggered but I could not find a documentation with all the possible binding on EditText. Any ideas how can i catch the first click on an EditText?
You can use the Touch event instead of Click to get the event to fire on the first click. Unfortunately, the behavior you described is normal to Android (even though confusing) and isn't related to MVVMCross.
As #hankide said, use the Touch event instead. You will need to create a custom binding. I happen to have just dealt with this so here it is:
public class MvxViewTouchBinding
: MvxAndroidTargetBinding
{
private readonly View _view;
private IMvxCommand _command;
public MvxViewTouchBinding(View view) : base(view)
{
_view = view;
_view.Touch += ViewOnTouch;
}
private void ViewOnTouch(object sender, View.TouchEventArgs eventArgs)
{
eventArgs.Handled = false;
if (_command != null)
{
_command.Execute();
}
}
public override void SetValue(object value)
{
_command = (IMvxCommand)value;
}
protected override void Dispose(bool isDisposing)
{
if (isDisposing)
{
_view.Touch -= ViewOnTouch;
}
base.Dispose(isDisposing);
}
protected override void SetValueImpl(object target, object value)
{
}
public override Type TargetType
{
get { return typeof(IMvxCommand); }
}
public override MvxBindingMode DefaultMode
{
get { return MvxBindingMode.OneWay; }
}
}
and in your Setup.cs put
protected override void FillTargetFactories(MvvmCross.Binding.Bindings.Target.Construction.IMvxTargetBindingFactoryRegistry registry)
{
base.FillTargetFactories(registry);
registry.RegisterCustomBindingFactory<View>("Touch",
view => new MvxViewTouchBinding(view));
}
Then you can bind to Touch instead of Click.
