I want to access my apps functions directly from the lock screen but I can't, it is only showing the app icon without the ability to click it unless screen unlocked,i am using my mobile with android 9 as emulator .
is there any way to solve it,thanks
as I found from Android developer website,it is not possible after version 5 as below
"The widget Category attribute declares whether your App Widget can be displayed on the home screen (home_screen), the lock screen (key guard), or both. Only Android versions lower than 5.0 support lock-screen widgets. For Android 5.0 and higher, only home_screen is valid."

Is there any way to use this feature on android devices with api lower than Nougat
ShortcutInfo is only available since API 25, and unless they release a support library for that, then I'm afraid it is not possible.
If your app targets Android 7.1 (API level 25) or higher, you can define shortcuts to specific actions in your app. These shortcuts can be displayed in a supported launcher.
Keywords on the page are a supported launcher, so the one on the Google Pixel might work, for example, but don't expect an LG or Samsung device to also allow the same feature
The current action for long clicking an icon exists, though. It allows you delete or move apps on your home pages, but, again, that's up to the launcher to implement and support that action.
This feature is supported in launcher. Long press on app icon is implemented in API 25 or higher, If the user doesn't allow the shortcut to be pinned to the launcher, your app won't receive a callback.
I want to force a widget to appear on the lock screen in Android.
Any ideas or code examples?
Thanks in advance.
First, the standard Android lockscreen framework only supports app widgets from Android 4.1 through 4.4, which is a steadily shrinking portion of the Android device ecosystem.
Second, there is no programmatic means, in standard Android, to force the user to add an app widget to the home screen or to the lockscreen.
I want to show my custom layout on homescreen or on lockscreen but i could not find any working example in Android 5.0 (Lollipop).
As suggested by #commonsware that this is not possible on 5.0 But how is this Next Lock Screen app is managing this on 5.0
I'd like to achieve something like this app, Any direction or help will be highly appreciated.
Thanks!
Android 5.0 got rid of app widgets on the lockscreen, so this is no longer supported. Quoting the documentation:
The widgetCategory attribute declares whether your App Widget can be displayed on the home screen (home_screen), the lock screen (keyguard), or both. Only Android versions lower than 5.0 support lock-screen widgets. For Android 5.0 and higher, only home_screen is valid.
The Adenda SDK lets you do just that. You simply design a fragment like you would in any other app and feed it into the SDK.
I'm affiliated with Adenda for full disclosure
Is is possible that a toast will get displayed of my application overriding every kind of lock in the device that exist when user press the power button twice in unrooted device. I am just few months old to android.
There isn't a way to override the lock screen but there is a way to co-operate with it. Starting from Android 4.2, you can write a lock screen widget to display custom information on the lock screen.
Update:
Only Android versions lower than 5.0 support lock-screen widgets. For Android 5.0 and higher, only home_screen is valid.

Im develping an app using apk 12 for 10.1 inch galaxy tablet. I would like to design a home screen only with my apps icon so that user will not be able to access anything else. Can I do that ? If yes, how ??

Yes, it is possible to create a home screen application.
If yes, how ??
There is a Home sample app in your Android SDK installation (assuming you installed the samples from the SDK Manager). It largely boils down to having an activity with an <intent-filter> using CATEGORY_HOME.
Note that the user who installs your app will have the option of choosing between your home screen and the built-in one. Even if they make your home screen the default one, they will still be able to revert that decision by removing your app:
by booting in safe mode
via the Android SDK (e.g., adb uninstall)
by getting into Settings through notifications and the like
possibly other means
For ur knowledge lot many thing are diff for honeycomb.
For your knowledge, nothing changed in this area with Android 3.0.
