2. All the activity should be visible on some secure key(predefine shortcut) pressed in mobile
3. i want access camera(front camera) without creating sound and image should be saved without preview.
No, you cannot do this on Android devices.

Here is the context:
In my app, I need to capture images, that's why I use camera intent.
This feature works perfectly, but only if the camera app was already been opened once before
Indeed, this issue appears only on a new device, or a new emulator
Here is the problem:
When I want to capture an image, the native camera app just open, giving to me some hints to how take pictures. That's not the camera app IN my app, but the camera app alone. I need to close this camera app, back to my app, and trying again
When I visit the camera app at least one time in the device's life, there is no issue
Here is what I'm looking for:
I want this camera app open in my app, even if it's the first time
I use the classic and official way to captures images

EDIT
I think the problem is because at the first time, the camera app asked for the location permission. So we need to open the intent without asking this permission, to keep the focus

There are ~26,000 Android device models. These ship with dozens, if not hundreds, of different pre-installed camera apps. The behavior of any of those apps on first run of that app will vary by app. Moreover, the decision of how those apps behave when they are first run is up to the developers of those apps, not you or me.
That's not the camera app IN my app, but the camera app alone
It is never "IN [your] app" if you are using ACTION_IMAGE_CAPTURE, as your question suggests that you are. It is always a third-party app, one of many pre-installed ones, or one of the user ones. And, again, the behavior of those apps are up to their respective developers.

Sorry, but that is not under your control.
I am developing an android application and i need clear the data of another application upon clicking an button.
i.e.: if i click button name "gmail" in my app,the data should be cleared of that "gmail" app
doubt:
1.Is it possible?
2.Do we need to be rooted our android device in order to do this?
° because greenify works with root access to force stop the other app flexibly.
I know that greenify works without root but pop that "force stop" ui screen of each single app to do that action.
MY APP FUNCTIONALITY:
I just wanted to develop an android apllication named "anti-theft cloud apps"
simply if an thief stols our mobile then my app detects when he changes the sim or an unique code send by mobile owner through sms from other mobile and logouts all the cloud based applications like gmail,google photos etc to protect our data to be stolen ,so in order to do that i thought of clearing other apps data(like gmail) PROGTAMITICALLY to logout. Is it possible
This is not possible with stock Android. You can do it with superuser, access root/data/data/PACKAGE and clear its content. But as seen in comment, this seems like evil thing.
I am developing a simple screen lock application.
I want that when I click on the app icon the screen gets locked and turns off. And am also able to do that, BUT before locking the screen the main activity gets launched (Set to Theme.NoDisplay) which takes time to get the device locked, which I don't want to happen.
So is there a way that I can turn off my screen (OR do something like starting Torch) without launching the app activity. If required I can also provide the code which i am with.
I think what you are looking for is android widget.
I have a Bluetooth device that I can connect to an android phone, and I need to launch a specific application when a certain button is pressed on the Bluetooth Device.
So on press A--> Application A needs to be opened.
As of now, I am attempting to build an android application which can scan for and connect to the bluetooth device, with a set of built-in keymaps (A->Application A, etc), and the application would open up the application corresponding to the keymap, but this approach has its limitations in that I was not able to successively select buttons to transfer between apps.
Would there be a way to directly interact with the android kernal from BlueTooth to try to directly open up desired applications?
There should be a number of ways to get what you want, depending on your circumstances. We can provide more help for specifics if you post some of the code you're currently using to start the apps. It never hurts to review the basics of using Intents to start Activities.
Just guessing, but you may need to bring the requested activity to the foreground if it has already started and something else has focus.
I am writing an App (MyApp) in Tasker that would need to read the State of a Toggle Button in another App (AppB) that I haven't written. It's for reporting purposes. I am a seasoned programmer, but are new to Android. Please bear that in mind:-)
Tasker have support for Java code, and have access to the full SDK of my Android 4.3 Phone.
The app will run on Android 4.3+.
I am already using AutoInput that is perfectly capable of getting the ID of widgets (Buttons etc) in other Apps, and AutoInput is also capable of Pressing these Buttons (AutoInput Accessibility must be turned ON). AutoInput will have support for what I am asking later, but I badly need it now!
So the question is:
How can MyApp get the State of a Toggle Button (with ID "toggle") in AppB using Java?
I am afraid this will not be possible by easy means. The applications in Android are isolated and cannot ask for others' applications controls due to the security policy. Without the access to the AppB code and possibility to change it this will not be possible.
The AppB would have to share the state of the toggle to your app: either via content provider or simple intent each time the toggle is changed. This requires changes in AppB code which I assume is not possible in your case. I see no other way to get around this.

In Android, by default each of the application runs in its own process and each app is Sand-Boxed.
Therefore, you cannot read the data from other application until it is shared explicitly by the particular application.
