Hi friends I put the finger on the screen on the android phone and the value of "ViewPostImeInputStage processPointer 0 or 1" occurs on AndroidStudio Logcat according to the uninstall status. How can I access this value through MainActivity, for example, to handle this value?

In setting menu you can find out which app have this icon.

Rooting the device is not recommended. This will void the warranty of the device, and it will limit the support that you can receive.
If u still want to do so try this step
It depends on which variant of the Motorola Moto E4 that you have. The Verizon variant (xt1767), for example, has an unlockable bootloader and cannot be fully rooted. The Sprint, Virgin Mobile & Boost Mobile variant (xt1766) can be rooted with these steps:

1. Unlock your device's bootloader by using Motorola/Lenova's website and bootloader unlocking support page;
2. Flash your device with TWRP custom recovery;
3. Using custom recovery mode, install Magisk v16.0 Systemless Rooting Interface, which is in the form of an archived zip file;

That's all there is to it. Of course, this is only a brief explanation of the steps needed to root the xt1766 Moto E4. Precise instructions and needed files for the job can be found at XDA Developers by searching for Motorola Moto E4 in the search box. Good luck.

Well, after a bit of research, you said that about the nandroid backup .. so I searched one with the sanders firmware and woops, flashed trough twrp and system working fine, android fine, everything is fine .. So i have to thank you cause you made me remember about the nandroid bk lol! Ty men. If everyone runs to this, just flash a nandroid.

yep always first backup everything before doing anything to the phone. nandroid backups are your friend. i would put a copy of the nandroid backup on your pc and even in cloud storage as a precaution.

Sorry for going off topic, but looking to get a real answer to this issue my brother is having.

My brother is in FDOC, he has a JPS5 it is having heat issue, shutting down in 10 minutes . He says the device showed he used 20% of power by just righting an email to me. With that said he says when he can plug it in, the system can show being in red(30%> before plugging in but sometimes show has being (50%<) has soon has plugged in.

It is hard for me to help him without knowing what apps or settings he can use for optimization of the system like cleaning ram and closing down apps running.

He just learned how to delete music he said, not sure if that says he doesn't know much on device or if it's more the way it has to be done with it connected to kiosk.

We are looking into possibly just getting a second player for him, how would any apps, books, music or what have you be handled (be lost?) Or is it kind of like the play store where he could get them back?

Looking for upper lvl support ( Manager to call) today, they happen to be in a meeting at the time, if no call I will call again and see if they are in a meeting again.

1)over heating and charging issues are most likely be a hardware issue. you can try factory resetting it and see if the issue persists. if it does then it is a hardware issue.

2)just have him reboot the tablet from time to time. this will clear cache and even ram

3)if you get another device as long as you sign in using the same google acct, all your app, music, and book purchases will sync up and you will not loose those.

4) not sure what you are talking about as far as lvl support and managers, but i hope they help you.

Ah, I was looking for a checkbox, that's why it wasn't there.

I did as you said, and now it works! Thank you!

@RLScott - thanks for the detailed explanation! It looks like about what I was saying, but with a LOT more detail on why it works that way. It's always good to understand why things are the way they are.

Fox Mulder said:

Pair them and then go into the Bluetooth settings for each device. Select only Calls or Handsfree for the headset, and only Audio or Media for the speakers, that should do it. The music might still stop during a call, that depends on app settings and how all the connected devices work with each other.

Oh perfect! Thanks so much!

As a FFM (former forum moderator) myself, I hoped you’d see the humor in my rib, but if not, my apologies. (And thanks to you and all the mods/admins who do a thankless task!)

To be honest I tend to pretty much ignore all things political, so this area of AF falls even below an afterthought for me.

Seriously, though, I’m sorry to have caused you extra work, as well as contributing to your “issues.”

I didn't see the humor, but I do now. I didn't take offense at all! I was trying to be funny in my response. You know... the kind of self-deprecating humor? No apologies needed at ALL! As far as contributing to my issues? That's quite EASY TO DO!!!!

svim said:

After re-reading the original posting I don't think I was misinterpreting anything. The OP apparently doesn't want sporadic notifications to be popping up, using Airplane mode would do just that, allowing one to disable/enable notifications globally. It was just a suggestion as there is no app currently available with enough Artificial Intelligence to read the users mind and determine which apps and services get cherry-picked options for notifications depending on the user's time schedule. At some point the user has to be involved in the choices he/she wants so no, Airplane mode isn't the best option but unless someone can actually provide one that is more appropriate, there doesn't actually appear to be a lot of alternatives.
A workable solution is to install a firewall app like NetGuard or Mobiwol, which allows a user granular control on how apps get online access through WiFi and through mobile data (although this won't block phone calls or SMS as those use basic cellular connectivity). Then it would be just a matter of enabling/disabling the firewall when appropriate. But I didn't bother suggesting it as it involves a considerable amount of set up on the user's part (picking which apps get WiFi and get mobile data access), something the OP specifically doesn't want to do.

Ha ha, and I don't think I am!

Let's see what the OP says when he comes back. Maybe we'll both be surprised.

Click to expand...

Hey svim & MoodyBlues,

I actually meant what MoodyBlues picked up. "dirty-and-down" forcing every app to the same default for everything regarding notifications. It actually could go both ways though, disabling every notification and then cherry picking every one where I want to get notifications like messenger, sms and cellular apps or the other way around where everything is on "popup mode" and makes a sound and vibrates and then I cherry pick everyone of them which I don't want to hear. But right now every app has it's own initial setup picked by the dev. So really what I want is to reset them ALL to one and the same state and then change them from there I'm aware of airplaine mode and do not disturb but those are like you said only something you use over a certain period of time but what I want to do should stay permanently

Yes I understand that there is no big demand for something this deep-going hahah I just want to make my android "perfect" You know, the average Joe would just mute a certain app if it makes some special notification which you don't want but I am aiming for not even having to get it in the first place and knowing when I pick up my phone what apps are going to give me alerts with a certain pattern like vibrating and making a sound.

Well well, then I'll be going through all my apps and setting them to my pattern and then picking the ones which should alert me afterward when everything is set to the same

If you have a phone that only supports one SIM it's not possible to use two SIM cards at the same time.

I use the Nexus 4 and I decided to update my phone because it hasn't been updated in like 2 months, I went to go update it and after the update it was very slow. It kept telling me 'Google play services has stopped working' it would just spam that. So I decided to wipe my phone to see if that was the issue. After I wiped my phone, I get to the setup part for your phone and I'm still getting the 'google play services has stopped working' I go on with the setup and I setup my internet, then after the internet I get to this setup part called 'Tap and go' I click skip on it because I don't need that. Once I click skip it just brings me back to the internet setup, I click next on the internet setup then it will just bring me back to 'Tap and go' It will just be an endless loop of me on this, I cannot get passed 'Tap and go'
Any kind of help would be amazing.

Kk does the Tap and Go require internet connection if yes then connect to the Internet

I was wondering what people’s thoughts are on the most effective pricing model for in-app purchases. Do you think you would make more money from pricing items individually and cheaply or bundling all items together for a larger price?

I’m thinking of in-app purchases for cosmetic things such as different color schemes, avatars etc where you could offer $0.50 per color scheme, or unlock all 10 for $2.00 for example.

I think for gaming apps, the little and often approach to unlocking new levels, vehicles etc would certainly win, but I’m less sure with a less ‘addictive’ app.

That's how I played games when I were young

And we see the collector object being zeroed out, which seems to be the reason for our crash.

The app crashes seen prior to this zygote crash also seem be to due to similar reason, collector object being NULL.

Debug approaches -
We have internally tried to use ASAN and malloc_debug to check is such corruptions can be caught.
Unfortunately, after enabling malloc_debug, issue was not reproducible.
And with ASAN enablement, device runs slow, and results in other unrelated issues.


Can you please help to provide any debug suggestions/ share any similar instances of this issue ?

I think it all depends on the specific launcher

A few years ago, there was a game that I found sweet and cute, and I'm looking to find it again. The only problem is that I've forgotten the name. Does anyone know of an app that involves a little planet you move around, avoid enemies, and it's constantly moving upwards? There are also perks you can unlock.

Thank you!

I will download it and see app is good enough or not.

Welcome to AF!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I hope to see you around.

If you are using a web page with a WYSIWYG rich text editor, it could be web browser. You may want to try other web browser or other version of it.

ok for future reference if you ever want to root any device, head on over to XDA Developers which is a developers forum where developers share their goodies. when you are there, check to see if there is a forum for your specific device. next check to see how active the forum is. if there is no action then to me it is not worth rooting a device. just remember no dev=no fun

so i looked for you and your specific device does not have a forum. there is a forum for the nokia 5.1, but no plus. even if you have just the 5.1 device, it does not look like 1) there is a root method and 2) there is no dev activity to make it worth it.

.........sorry

Yes it should show the combined capacity of both storage, for example my phone with Android 6.0
