How do i get speed

Hi guys, I am sk. I still keeping this phone. Sorry I might be too late to join as the phone is old. However, I ported twrp 3.3 to our device thanks to a porting guide "porting twrp without source" and loki tool from xda. I am not a developer, just want to try something new. I play with the phone during my free time.

I have never used android so I know very little about the os. I do know about some apps that are available though and just discovered the “activity” feed and “frequently contacted” in email. I can see in the google play store that the “Vault” app was downloaded to hide certain information (pics/videos/chats). If someone uses this app, how would it appear in the activity feed? Is this one that can be disguised as a clock or calculator? I see a bunch of activity for a deskclock app and can’t understand why a clock app would be used so many times a day. And are APK apps used in a way that would relate to the hiding/secrecy? There was was only one email in the “frequently contacted” and no one in the contacts. While knowing the FC list might not be accurate, could someone end up there at all if they were in fact not contacted? Sorry I know it’s a lot. I appreciate any help.

I've created a GPS-app, which shows my current location on a map on a Android Emulator via Android Studios. Now, as the title mentions, I've been trying to get the nearby places to work for a really long time now, without any success. As it seems, most of the video's and guides I've looked at has been updated, and I really don't know what to do. This is how my app currently looks like:

Application Image

I've created a button to locate all the resturants, since I have to start somewhere. I've created the API-key and enabled billing for places. I've fetched the demo api and created a model from it with different Pojo classes, such as Geometry, Location, MyPlaces, Photos, Results, etc. These contains methods that can be used to get information from the locations.

Now I need to create a method called something like nearByPlace();, but I don't know how to implement it correctly, and this is what I need a bit of help with. This is what my MapActivity looks like:

Hi everyone .I have an s8 that I didn't have backed up for the last 6 months . I'm curious if anyone could help me get out of this bootloop it's stuck in. It won't turn on for more that 5 seconds then resets. I'm need to get my photos back and was wondering if anyone could fix it for me without doing a full phone wipe?

[EDIT] A newer update has been released for the OnePlus 6T on Open Beta 4. See post #6, below.

You will only receive this test firmware OTA if you are already on their Open Beta releases. This is their 4th Open Beta release for Android 10 in 3 months.

IMPORTANT: Before installing this Open Beta 4 update, you must have previously installed Open Beta 2 on your phone at some stage, to prevent issues.

I've been finding Android Studio pretty frustrating, mainly because of how often things change with it. It might just be because I'm still learning to use it and finding my way around doing stuff. But I'm just kinda annoyed that I don't really know what I'm doing and if I try to look up on the internet, I often find outdated information.

But before I spend more of my will power learning to make apps on this, is there a better alternative I should give a try? What do you write your apps on?

I'm trying to disable a Time Picker in Clock mode so that the user can't change the hour/minute when a button is pressed. I'm using setEnabled(false) but this only greys out the header clock and doesn't allow you to select hours/minutes/AM/PM, but the selector is still enabled and the hour/minute can be changed. Does anyone know how to solve this issue?

Thanks

How can I temp disable the pull down notification bar for when I'm gaming? Hope there is a way bc sometimes I'll accidently touch the top of my screen which pulls it down mid game (example: claw method on PUBG mobile)
Using an xperia if every makes different.
TIA

Hi,
i'd like to know how to set the Samsung S10 phone so that a message notification sound will play for a new message when the message thread is already open on the screen. i have to get out of messages every time just to be able to hear when a reply comes through. it's most annoying.
is there a way to fix this?

I've just upgraded to android 10. When I copy new music libraries to my Galaxy S10e, album art hidden in Folder.jpg files suddenly appear in Gallery. Existing artwork, some 900 files, do not appear in Gallery, as expected.
I can't see that I'm doing anything wrong.
Help?
Simon

Suddenly there are downloads that expire and I can't find them on the phone. Anyone know where to locate them? This hasn't happened before.

I'm having a tough time deciding between these 2 phones. I'm only looking to spend $250. I'm on verizon. I was set on the Moto G7, but then I started to find reviews where users said that phone has wifi connectivity problems - frequent disconnects from wifi and unable to detect wifi. This scared me away from the G7 a bit.

Please let me know your experience with either of these 2 phones and/or your recommendation and reason.


Thanks,
DJ

Hi,

We're a small start up in recycling, and our app developer has advised we need both places and maps api so a customer registration form will autocomplete. We understood that we only need the places API Given we are only trying to make sure we don't overspend, can anybody let us know

1. Can we use Places API solely for a registration form
2. Why would we need both maps and Places API's

We have no map functioning the app and there will be no navigation to locations through our app. We only want to pick up the users address when they try to register with us.

Thanks

All credit for this idea goes to @LV426. Could we please have a new board for spirited discussion?

If you're interested in its genesis, please start reading this thread at this post.

The gist of it is: P&CA is a shithole!

There, I said it.

There are members--and potential members--who would love to have rational, respectful, intelligent discourse on various topics, but won't go near P&CA because of its vile tone. Yes, I know, I get it, P&CA has its set rules...but it just doesn't work. I have loads I'd like to talk about, but you won't find me in P&CA...

In both real life and online I've seen how opposing opinions can be discussed in a respectful manner, no mud-slinging or name-calling involved. I've seen people change their stance on an issue after participating in respectful, but animated and informative discussion.

Please consider a new board, with a new, inviting name (Friendly Banter, perhaps?), its own clearly defined rules, tight moderation, and a zero-tolerance policy for infractions. The rules would make clear that the board is for discussing topics, not members, that you're free to voice your opinion and your reasons for disagreeing with others, but you cannot attack others because of their opposing viewpoint.

We want more members, right? And more, and better, discussions? Try this! It may help.

hello, does anyone know what application is this? i got this from notification status bar. thanks.

I had completed my project done but when it came time to compress it in one drive I moved it a bit and my project which is a folder lost most of its contents all my Gradle files are gone. Please help me restore everything because I'm really panicking.

I am unable to connect to wifi networks that require you use an account and password (work or school wifi networks) on any android device. I have tried it on a Google Pixel, a Samsung S8 and an S7 edge. When I use my credentials, it just says "unable to connect to xxx" How can I fix this?
Any help will be appriciated.

I have a Polaroid P5046A smart phone (which is never on any list) and I found drivers for Windows but I can't get any of them to stay up. Sometimes a driver will work as long as I don't reboot the computer but that's the best I've had.

Does anyone know where the best driver can be found and/or why mine won't continue to work after a reboot?

Thanks - rev
