How to solve slow Bluetooth RFCOMM rates on current tablets

Android Slow Bluetooth RFCOMM Transfer Rate with RN4678 - Stack Overflow

It seems like almost all newer tablets have this problem. We previously used the Lenovo M10 Plus FHD 2nd Gen which did not have this problem. We are trying to switch to the Samsung Galaxy Tab A8. I don't believe this is due to interference despite the answers on Stack Overflow (considering the old Lenovo tablet worked fine). I tried things like adjusting the buffer size and changing the interval of the keep-alive command, but it didn't have much of an effect.

BTW, this isn't file transferring, but reading live data from two load cells connected to a board via Bluetooth (Classic, not BLE).

Help Digital Stylus for Pixel 6 Pro

Does anyone have a digital stylus that works on our Pixel 6 Pro?
These are the necessary criteria:
1. Works on Google Pixel 6 Pro.
2. Has 2 ends, fine point that needs charging thick cloth end charge not
needed
3. Does not turn itself off while using it.
My old Meko was perfect but is wearing out. So far, all the new ones I've tried don't work, even though they said it did or they turn themselves off while using them. It drives me crazy.:maddroid:
Please help.
Thanks

Google Contacts Question

I just recently finished importing 855 records into Google Contacts for a friend. His database goes back to the earliest days of the Palm PDA when only seven-digit phone numbers were required when dialing from within an area code so he has several hundred seven-digit phone numbers in his Google Contacts.

I don't remember where, when, or in what program I saw this but it seems to me I saw a program that had a setting in it that if the area code was not part of a phone number (in other words, seven digits) there was a place to enter a default area code that would be automatically dialed with it.

Is there such a setting in Google Contacts?

Help Question about calculator

Our Pixel 6 Pro has a built in calculator that is accessed with a shortcut. My question is about it's settings. I cannot find them. When completing division, the answer is given with a fraction. I prefer answers with decimals but cannot figure out if that is possible. I have downloaded a calculator app that uses decimals but I'd rather use the included app.
Thanks for your time,

Failed to take any photos. Error msg: Insert an SD card. What's wrong at all?

Hi,

I created an AVD on API Level 28(Android 9.0). But when I tried to take a photo, the stock Camera app said "Insert an SD card before using the camera". So, I failed to take any photos at all.

failed to run the Camera app in Android 9.0 AVD.png



But in fact, in the AVD settings, there is a Studio-managed SD card for this AVD.

What's wrong with this AVD? Could I have the Camera app on this AVD work without an SD card?

I have cleared storage of the camera app. But it doesn't work yet.

Help Why would a group text message get sent to each person individually rather than as part of the group

Hi all. There is a group chat going between my mom, my sister, and me. My mom responded with a text, but somehow it went to me and my sister separately, i.e. it went to the text message thread of just my mom and me on my phone, and the thread for my sister and my mom on my sister's phone. My mom's phone shows that it went to the group chat though! Other texts seem to be going to the group chat normally so far.

Any reason something like this might happen?

DVD theory..

I am talking about normal dvds, I know a few of them rent from redbox, or their local library, now the way people handle them is insane of having the scratches due to wear and tear, even if pausing them on forever and going to use the kitchen for a long nap or something, that does either hurt it because of dvd players or anything, now I usually slip one in and leave it playing, or turn down the volume, put it on mute whenever someone is talking to me. I have older ones that get so scratched up plenty of times and will not play.

Like Family Guy, Space Ghost C2C, Sing, Ugly American ones, just ontop of my head, but when I binge on anything I leave it on and wait until it is finished to pop out my ps3.. and look at the underneath due to scratches...

Anyone else get that right away of getting it on pause and then having it scratch up?

Suddenly lost all mobile signal.

My phone suddenly lost all signal. The signal strength icon shows a circle with a line through it. I have replaced them sim, tried other sims and the 2nd sim slot. I have done a factory reset on the phone it its still the same.

I dont know what the fault could be. is there a way of telling if it is the SIM card reader or something else? The SIM manager shows my phone number but then Unknown, in what I presume should have been the carrier name.

I can get a SIM repair through SAMSUNG for £99 but I dont know if that will fix the problem. I dont want to spend that much only to find out it isn't the issue.

Are there any suggestions to see if it is a SIM card reader issue or an larger fault with the phone.

Cannot rebuild after changing targetSdkVersion

I have a legacy app and no desire to update it but Google Play told me I have to increase my targetSdkVersion to at least 31. After some experimentation, I changed it to 32.

I now get three red lines in my build.gradle:
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

Hovering on one of these, it told me I needed to upgrade to AndroidX, which I did by choosing Refractor>Migrate to AndroidX... It did some stuff, don't know what. The red lines are still there. If I try to rebuild, I get fifteen errors in values.xml saying "Android resource linking failed" on lines starting:
<declare-styleable name="Constraint"><attr name="android:orientation"/>...

I have upgraded Android Studio to the latest version. Any suggestions what to try next? I find it enormously frustrating that a) I am forced to change my target SDK for an app that hasn't changed in three years and b) when I do, it seems to open a great can of worms and I'm beginning to panic that I will never get this app to compile again.

I have decades of experience as a developer but I don't really understand gradles and stuff. I just want to write some Java and turn it into an app. I seem to end up fighting the developer tools all the way.

App not Installed error when updating the app by installing updated apk file

I have installed latest Android Studio "Android Studio Dolphin | 2021.3.1 Patch 1" in my new laptop and copied existing App folder and its jks file.
I am able to generate Signed APK file in the new Android Studio after updating
versionName in app/build.gradle file. If I install the new apk in my mobile (where the app is already installed with previous versionName), it says "app is not installed" error.

In my old Android Studio, I was able to update versionName, generate apk file and able to update the app.

Could you please tell what could be the issue.

Note:
- my apk/app is installed in the mobile by enabling "allow from unknown sources".
- in old Android Studio, while generating Signed APK, there were options for Signature Version as V1 and V2. I used to enable both of them to generate the apk. but in the latest Android Studio, it is not shown. Could that be a reason ?
