Android Listener for Wrong Lock-pattern
(1 answer)
Closed 9 years ago.
I want to develop an Android App that will perform some action when a user enter invalid pattern lock or pin code while unlocking the mobile. I don't know much about it. Any body can guide me?
Create a DeviceAdminReceiver set to handle the ACTION_PASSWORD_FAILED events, which your receiver would handle in onPasswordFailed(). You can read more about the device admin APIs at: http://developer.android.com/guide/topics/admin/device-admin.html
Edited:
I think it is possible, but the screen lock runs on it's own sandbox environment.

I am recently working on android at initial phase. In my app I want to add a login page with 6 digits. after entering 6 digits correct pin user can go to homepage. I don't know which methods should I use or how can I do so. It will be my pleasure to get some help on this.
You Have to try some code and ask if some error is occurred. StckOverflow is palace to clarify technical doubts .not a place to ask for opinion. Try to change your questioning pattern.
You have to use TextWatcher() for achieve this.

Listen to volume buttons in background service?

Closed 5 years ago.
I am making an application and I want to make app in such a way that user directly open that by using volume key, suppose user click twice the volume+ or volume- buttom and the app will directly open without home screen or without any interuption.
I want to add this functionality using the code in Android Studio. If anyone know how to add this, please help...
What you are asking for is not App/Code nor Android Studio related but device related, If the Original Equipment Manufacturer will allow a device to have a shortcut button it could be possible to achieve that on those devices.
Cheers.

How to access device settings programmatically?
(6 answers)
Closed 6 years ago.
I want to make a code to enable the developer mode and set a parameter on this ( the one to always allow roaming detection so we can switch to a better wifi if found).
I saw some apps that can launch developer mode, but nothing is opening it AND changing some parameters. I can't ask to users to set this parameter themselves, so how can I make this myself?
I saw also that we can do this by shell :
adb shell am start -n com.android.settings/.DevelopmentSettings
But afterwards i don't know how to set automatically a parameter.
As I made my own app, I could launch developer mode and this param on the start of my app.
Did anyone made this before inside of an app?
How can I call DevelopmentSettings activity inside my app and edit some of its parameters?
Thanks
EDIT
I can eventually root all my phones and set my app inside system folder, It can be complicated but we could manage it. If I does, How can I access to the parameters of developer mode programatically?
You can use following code but you need root access for this.
.Settings.Secure.putInt(getActivity().getContentResolver(),Settings.Secure.ADB_ENABLED, 1);

Is there a way to get current activity's layout and views via adb?
(8 answers)

I write a testing automation for some android application and I want to tap on application elements like buttons by their ID, I know if it can be done by writing an android test application and install it on device (like Espresso, UIAutomator, etc...), but I don't want to use this approach.
Is there a way to do it from Android Debug Bridge? Maybe someone know some sort of tool similar to monkey-runner that can perform it? Basically what I ask - Is it possible to click buttons on Android by ID via ADB?
This is possible by using AndroidViewClient, and it is basically done by creating a python script and executing it. Note that this works best if these buttons contain some text or an ID to differentiate them from others. More information can be found here: https://github.com/dtmilano/AndroidViewClient/

You can check android-screenshot-library, which should work without a root access; however it still have some limitations
Also AndroSS is another option for Tegra-based Android phones
