I wanted to know since the tab has a screen that is 3x as big as a Galaxy S (3 phones put side by side on the tab) is there an app or a home launcher or something that will allow me to have multiple things running on different screens.
For example, I need to take information from one document and organize with another and I can easily switch between them on Windows and Linux.
I then need to tag along to other places and want to continue to edit both documents on my tab, I have to keep opening one document then remember a sentence or piece of information for a second and close that document and open the second one to continue typing it up.
It is a real hassle and very time consuming and frustrating. Our tabs are pretty big and I would like to utilize it to the fullest of its capabilities as a tablet/big smartphone.
What my suggestion is if anyone feels like making an app that I can do just this and more on my tab, they couod design an app that works like the home screen.
For instance you open a document, email, or webpage and want to look at another document or note you made for yourself or another email. All you do is swipe to the left or right and it is a clear home screen or something to that effect or maybe a list of documents, notes, emails, webpages you can open. You then choose/open what you need and can continue with the first page having the second one open for reference or whatever the case may be.
You can then easily switch between the 2 or however many pages you have opened just by swiping the screen just like you would your homescreen.
If someone knows of such an app or had the resources to make one please let me know.
Also this would make for a great multi-tasking app if made correctly.
What might be an issue here is that most programs themselves are going to detect the loss of focus and handle things. Either saving/reverting to front screen/closing down completely, or leaving things up and running.
I can see what you're after, more a 'cards' type thing, and it might be possible, but you'd have to override what the OS is sending to the apps (don't send the lose focus thing), or get the apps to handle things differently.
Either going to be impossible, or trivial. And even if it was possible to be hacked, apps are going to be assuming their running and might use more power. The way it works at the moment is to assume you're being shut down, and handle that gracefully so you're using minimal resources on a phone.
If one were to change how android handles the multi-tasking, would this sort of app be possible?
Another question is, are there any document editors that can do something like this?
I have an iPod Touch and an app named iFile, and it has multi-window type thing that I am describing where I can open many pages and view many documents at a time.
That's the main thing I want it for, editing documents without having to open and close constantly.
I was thinking of this the other day. This would be something you'd have to build into a ROM. It'd be a nice mod, and since Android already takes screenshots for the recent apps bar, it wouldn't be too hard to implement once the source is released. My thought is it would be a four or five finger gesture left or right. It could possibly zoom out similar to how the screens zoom when you drag an icon on the launcher so that the other tasks could be visible at the same time. The normal activity lifecycle would continue as usual (i.e. onPause() would be called as soon as the gesture starts, and onStop() once the activity is off the screen). A screenshot would be used in place of the actual Activity until the gesture is over (meaning the Activity has "snapped" into place).
There are many C++/CX codes in my Windows Phone 8 app so there might be many dangling pointers access which will cause AccessViolationException. Actually I know that __try & __except can catch them but I hope that my app can get notified like some callback function can get called while AccessViolationException raised that it's NOT surrounding by __try __except.
And I have tried Application.UnhandledException in C# code and ::SetUnhandledExceptionFilter(which is private API and I somehow successfully invoke it) but still failed to get called.
So is there any way to get notified while AccessViolationException is raised?
In case somebody has the same problem, I solve my problem by using _set_se_translator, a crt API
Ooh, details on that would be good (OK, I should just go read the docs...) but thanks for posting the solution! C++/CX has way too many modes of memory management; it's pretty easy to get it wrong if you try doing anything even vaguely outside the standard use cases. (Example: Do not malloc an array of Platform::String and then assign to it. Any non-nulls in the array (leftover data from prior allocations) will be treated as though they are valid strings that you are assigning over, which means the "old string's" reference count will be decremented, which may lead to memory corruption. Using calloc instead works, by the way, though it's still kind of a hack.) Anyhow, debugging that stuff is annoying, especially since you can only debug native *or* managed, not both.
Reposting from where I previously put this, on the suggestion that folks here might have more idea what I am talking about.
Yes, this is a question but I couldn't see that it fit in better to one of the other forums. If I am wrong please accept my apologies and redirect me, thanks.
I'm trying to work with a custom build of Android based on KitKat to incorporate a stylus, copying some of the functionality (though not code) from Samsung which sells Android-with-stylus builds for e.g. the Note 3. I'm not including details of the specific device because right now I am working on a custom dev device and my aim is to write code which is generic enough to be usable from any Android (based on KitKat). The build (written by others) already incorporates drivers and sends stylus events correctly as motion events etc. Programming at the app level I can receive onHover, onTouch, onClick etc
The specific functionality I am trying to achieve is to pick up a stylus-button-click while hovering. It's perfectly possible to do this in any app, using an onGenericMotion Listener.
However, I want to make my "stylus-action" have system-wide effect - so that anywhere (in any other app, or in the launcher or whatever) I will pick up the event (prior to any other app) and bring up my custom menu. (just like AirCommand in Samsung Note 3) I guess in my custom Android this would then make that particular action somewhat protected or unusable for other users, but I'm ok with that.
In older Android (prior to ICS) you could try something by putting up a System Overlay (i.e in regular app code, without hacking the ROM at all), but this is no longer possible.
This is not an attempt to tapjack or whatever, I understand why this functionality has been removed from the domain of the regular programmer, and I don't want to regress my ROM back to pre-ICS behaviour by allowing the System Overlay hack. Now I am programming the system (if my change is good enough I'd like to submit it back to AOSP) so I would like to know the best method to address this. Since Samsung have already done this, it must be legal (using legal in the terms of "Android will allow it"), and I want to do it right.
Is it possible to write something similar to the System Overlay when you are running from a system service? Or is there a good choke-point to capture events before they are broadcast to the current running apps?
I was looking at (sorry, not allowed to post links) AndroidXRef /frameworks/base/core/java/android/view/View.java specifically in the function dispatchHoverEvent() which looks like a promising place. My naive idea is that I would place code here checking the MotionEvent to see if the button is pressed and if it is, don't call any listeners and instead call my little menu app (or broadcast a custom message, or something anyway). However, I've never written code on the ROM level before (LOTS of experience writing app code) so I don't know if this is a really bad point or a good point to add in code. Should I be putting things at a higher level or a lower one? Will this capture all events or not? Is it all just trial and error?
If this is the wrong place to ask questions like this, please tell me where on XDA I should be asking it. If it's the right place - please answer
Thanks

the problem is, i use OP5T, and none of any 8.0/8.1 stock custom rom does support 18:9 scaling feature like in OOS, this feature named as "Full Screen Apps" under app category.
after a few googling, i came up with these method:
1.) add/inject/force this into manifest file of every installed app. or maybe doing some workaround with the packagemanager
<meta-data android:name="android.max_aspect" android:value="2.1" />

2.) playing inside AOSP source code, parsePackage method.

i know nothing of creating xposed module, but before starting my journey, is it possible to do the first method with xposed?
after seeing module like Xinstaller, App Settings, and XAspect. i thought it may be possible with xposed to approach this.
really appreciate every kind of help, thanks before
I can see at least two solutions there.
The first one, probably the most simple.
1)
Hook parseMetaData method to add
android.max_aspect to returned bundle in after hook (if doesn't already exist)
2)
Hook setMaxAspectRatio
Get mAppMetaData of passed Package (owner.mAppMetaData) in before hook and add android.max_aspect to it (if doesn't already exist)
Edit: Apart from <meta-data> app dev can also specify aspect ratio within <Activity> element in the manifest.
This has higher priority over <meta-data> so the best solution would be to hook setMaxAspectRatio of Activity class and modify maxAspectRatio parameter to desired value in before hook.
Have decided to rejoin XDA after a while off to see what sort of response I get to this.
A browse of the forum tells me that there is no known way to unlock fastboot, I was wondering what methods had been explored in an attempt to do this?
More specifically there are 2 potential methods I'd like to ask about.
1: I have seen mentioned in a comment here a tool I stumbled across a few months ago while messing around with another device,
edl/README.md at master · bkerler/edl
Inofficial Qualcomm Firehose / Sahara / Streaming / Diag Tools :) - edl/README.md at master · bkerler/edl
github.com
There is one option in particular that I think is of interest,
edl modules oemunlock enable -> Unlocks OEM if partition "config" exists, fastboot oem unlock is still needed afterwards
2: After a quick browse of the disassembled Oppo deeptesting app I can see a number of references to a class that is only accessible via reflection 'android.engineer.OplusEngineerManager'
and it contains a method 'fastbootUnlock'. Has anyone tried to access this class and its methods at all?
Maybe none of these things will be of any use, but before I spend too much time exploring them, I was interested to hear if anyone else had explored these at all? If so what progress was or wasn't made?
A little update for anyone who is interested:
So I have spent a little bit of time this morning seeing what I can do with the 'OplusEngineerManager' class. I made very simple app to see what access I could get to this class. After adding a library to allow the use of reflection to access non sdk classes I was able to get a list methods from the class, but so far have not been successfully invoke any of them, despite there being no exceptions caught.

I took a look at the fastbootUnlock method itself (at /system/framework/oplus-framework.jar) and I believe that even if we could invoke it, it wouldn't work because it uses some sort of token (generated be Oppo?). I might be wrong though, I don't have much experience working with decompiled code, and the code I looked at was Realme one (I guess its same as Oppo).

Its great that someone else is looking at this! I hadn't posted another update as I haven't made a huge amount of progress, and I wasn't sure anybody would be interested.
The fastbootUnlock method returns a boolean and takes 2 parameters, a byte array and an int. From what I can see it is the only method of the OplusEngineerManager class that the deeptesting app calls. It contains 2 calls to the fastbootUnlock method. Once where it calls it with an empty byte array and the int is 1. I was actually able to invoke the method from my test app in this way and got a false return value (rather than just getting null like the other methods I tried to invoke). The second is contained within a method of the deeptesting app that takes a string as its parameter. It then converts this string to a byte array which it passes as the paramter for the fastbootUnlock method along with the int of 1.
Edit:
The second call to fastbootUnlock uses the length of the byte array as the int and not 1. Please forgive me it was late when I wrote this and I was not looking at the source.
Thats about as far as I am with it at the moment, the next task is to find out what that string it passes is exactly, and is it something that needs to be generated by Oppo.
I would imagine the realme framework woukd be similar, if you would like to compare I can provide the full list of methods from the OplusEngineerManager class?
Hey guys, I would be interested in helping you somehow.
I have no prior experience with unlocking a device. (besides actually doing it with the tools provided by anyone else).
But I own an oppo find x3 pro, if you need me to do some testing for you, let me know
Thank you for your reaserch and trying to unlock the fastboot!

Hi, thanks for your reply. At the moment there isn't too nuch to test, but if I do manage to find a way I will need plenty of testers, so thank you
A small update:
I have found that the method in the deep testing app which takes a string and then ends up invoking the reflected fastbootUnlock method is called by a handler associated with one of the app's activities.
The handler gets the string extra from the intent which starts the activity, and then passes that as the parameter when calling the method.
The next problem is that I cannot find anywhere in the deep testing app that starts this activity. I can see as part of, what I believe to be, the normal flow of the deep testing app that an activity in the startup wizard is called, so I wonder if the startup wizard then starts the activity of interest in the deep testing app. This will be the next thing I look into
Edit:
I have looked into this more and it turns out most of this is wrong. The activity is started from within the deeptesting app and not the startup wizard

Great, from my side I tried running the fastbootUnlock method as you did, and got the same result (false). I looked at the logs and there was a selinux denial for finding the engineering service as my app is an untrusted app, so our only way to run the fastbootUnlock method is through the deep testing app I guess.

Do you mind if I see the logs? I have had no such denial that I can see.
How have you enabled access to hidden apis?
Have you used any of the permissions from the deeptesting app?

There are the logs. I enabled hidden apis, yes, didn't add any extra permissions though. By the way, did you use some specific keys for signing the app (platform keys for example)?

I had a closer look at the logs and I can see that sadly I am getting the same SELinux error.
I can't see much of a way around it at the moment.
I have made a thread in general should anyone wish to discuss this further. Most of this is applicable to all Oppo devices and there are people that have looked at this in different ways and found different things out when trying to unlock fastboot on other devices. I think it would be useful to have somewhere to discuss unlocking fastboot on Oppo devices in general.
