Cannot read serial data using USB Host

saramarz
hi casjkent2
you could try is to make sure that you have the necessary permissions to access the device. You can do this by adding the following code before you start the transfer thread:

Code: 
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
PendingIntent mPermissionIntent = PendingIntent.getBroadcast(this, 0, new Intent(ACTION_USB_PERMISSION), 0);
manager.requestPermission(device, mPermissionIntent);

You will also need to register a broadcast receiver to handle the permission request response. You can do this by adding the following code to the onCreate method of your activity:

Code: 
IntentFilter filter = new IntentFilter(ACTION_USB_PERMISSION);
registerReceiver(usbReceiver, filter);

Make sure that you have added the necessary permissions to your app's manifest file:


Code: 
<uses-permission android:name="android.permission.USB_PERMISSION" />
<uses-permission android:name="android.permission.USB_HOST" />

A link is already included in the op. My point is that if you want to promote something, visuals are very important. If you don't have that, I don't care very how good the app is, I'm not inclined to check it out. If you go all out in advertising and promoting, I can be persuaded to check it out. But, a very brief explanation and a link to the app is not going to make me want to do anything.

Starred vs VIP contacts

Hadron
Funny thing is that it's normal for DND to have an option to allow calls from favourites through (but it's an option, you can choose not to do it). So it sounds like the main difference is ringing when the phone is set to silent.

One of the good things about Android is that manufacturers can vary things, add their own features, etc. But it does mean that it's not easy to tell what is "android" and what is "manufacturer X".

New App: Short Video & Funny Videos by Doston with Rewards (Version 1.1.0.8)

AlexFox97
They haven't yet purchased advertisements to promote the software. When you browse Facebook, YouTube, or Instagram, you won't see any earn video advertisements. The spread of Byte depends on both word-of-mouth and accidental App Store discovery (and we do get many new users daily). The staff made this choice with great thought. If they purchase advertisements, they must be both very costly and successful. The second ad won't be effective on an user who has already tried Byte once and left after seeing it.

No wifi calling on colorOS V11

slamdunk58 said:
So T-mobile has to set up wifi calling for every different make and model of android phone? That sounds like a crazy system! OK, thanks for your help.
Click to expand...
No that is not how MVNO carriers, like Tello, work. You still need to contact someone at Tello to be sure you actually have WiFi Calling enabled in your account. Tello is your carrier, T-Mobile is just the carrier network provider that Tello is contracted with. As far as T-Mobile is concerned, you don't exist.
And it's not so much that Tello, your carrier, supports WiFi Calling nor that your phone can support WiFi Calling but if your account with Tello allows you to use WiFi Calling. It's in their hands so let them deal with this. You might need to new SIM card from them, or it might be a matter where you need to disable 5G in your phone's Settings menu. Your phone only supports up to 4G/LTE.

Is it possible to sort photos from your photo picker, or is there an app you can install?

svim
Which photo manager app are you using? The stock Gallery app? The Google Photos app? They all should have some basic sort and display option so you can adjust how your photos are shown -- i.e. oldest or newest first, large or small thumbnails, etc. The thing is each app will have a different user interface so you might need to peruse through the app's Settings/Config/Options menu or there might be an icon in a upper or lower menu bar.

One of the most versatile and user configurable photo managers I've encountered is Simple Mobile Tools Gallery Pro app:
https://play.google.com/store/apps/details?id=com.simplemobiletools.gallery.pro
Go through the app's Settings menu to take advantage of all its optimization and customization options.

.Nomedia with F-Stop photo viewer

svim
Keep in mind that a .nomedia file only applies to multimedia apps so it's only about image and video content. So yeah, if you don't want the F-Stop Gallery app, the stock Gallery app, the Google Photos app, the VLC app, or whatever media app to not automatically scan, index, and display any of the content of a specific folder than you just need to add a .nomedia file.

But the Google Backup and Restore service that's a part of Android, that relates to the content of the file system, and a .nomedia file is irrelevant. Unless you intentionally created that PHP folder inside a Google app directory, odds are it's not included in your online Google account backup.

Help Android Auto on Xiaomi - Low resolution image casting

T
[SOLVED]
@everyone:

I found a way to "get around" the problem. Using the "official" AAWireless dongle ( https://www.aawireless.io/ ), so not using the cabled USB connection, i had no more resolution problems.

I know that buying something else isn't a real solution, but at least this is a way to use AA in a good quality.

Actually there are a lot of cheaper dongles than this on Amazon, but i didn't try them, so don't know if they will resolve aswell the problem.

Hope this will help anyone that was in my situation.

How to get value from TextField

James_Watson said:
Hi, any ideas about this issue? Thank you in advance. :)
https://stackoverflow.com/questions...oad-media-when-trying-to-crop-a-jpg-picked-fr
Click to expand...

This could be happening because the app that you used to pick the image (in this case, Google Photos) is returning a different URI for the image than the one that was originally used to save the image on the device.

As for the reason for the change, it's possible that the app is using a different storage provider or a different scheme for representing the URI of the image.

As for whether this URI change is causing the cropping to fail, it's hard to say without more information. It's possible that the cropping app is unable to handle the URI that is being passed to it, or that there is some other issue with the image or the device that is causing the cropping to fail.

It's also possible that there is some difference between the AVDs that you are using that is causing the app to behave differently. For example, there may be a difference in the versions of the Android operating system, or in the configuration of the AVDs.

To troubleshoot this issue, you may want to try the following:

  1. Log the URIs of the images on both AVDs to see if there are any differences.

  2. Try cropping a different image on both AVDs to see if the issue is specific to a particular image or if it occurs with all images.

  3. Check the logs for any error messages or other clues that might help explain why the cropping is failing.

  4. Try using a different cropping app to see if the issue is specific to the app that you are currently using.

Excel app won't open spreadsheets

AlexFox97
I also had such a problem. I noticed that in general, all Microsoft products do not work particularly well on smartphones. Maybe the problem is that you are using an un-purchased version? Personally, I downloaded the hacked version from microsoft office professional plus 2021 product key and maybe you downloaded your version of the program from an unverified site? then an incorrect repack of the application may cause crashes. Until I found a good key, I had it. Therefore, be careful and choose only proven sites. It is best to buy original applications on the official website.

RatingBar

saramarz
To change the number of stars displayed in a RatingBar in an Android app, you can use the numStars attribute in the layout XML file. Here's an example of how you can do this:

Code: 
<RatingBar
    android:id="@+id/rating_bar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:numStars="5"
    android:stepSize="1.0"
    android:rating="3.5"
    android:isIndicator="false" />

Make sure that you have set the numStars attribute to the desired number of stars. In this example, the RatingBar will display 5 stars.

If the numStars attribute is not working as expected in your app, there may be other issues that you need to troubleshoot. Here are a few things you can try:

  1. Make sure that you are using the correct layout file. If you have multiple layout files for different screen sizes or orientations, make sure that you are using the correct one.

  2. Check for any errors in your layout XML file. You can use the "Design" tab in Android Studio to check for any layout errors.

  3. Make sure that you have correctly implemented the RatingBar in your app. For example, you may need to set the android:id attribute and retrieve the RatingBar in your code using FindViewById.

  4. Check for any errors in your code that may be affecting the RatingBar. You can use the "Logcat" view in Android Studio to see any error messages that may be relevant.

Error Gradle in Android Studio

saramarz
The error message you provided suggests that there was a problem resolving the dependencies for your project during the build process. This can happen for a variety of reasons, such as:

  • A dependency that is specified in your build file (e.g. build.gradle) could not be found in the specified repository.
  • There could be a version conflict between different dependencies in your project.
  • There could be a problem with the repository itself, such as it being unavailable or unresponsive.
To troubleshoot this issue, you can try the following steps:

  1. Check your build file (e.g. build.gradle) to make sure that all dependencies are correctly specified and that there are no syntax errors.

  2. Try running ./gradlew clean from the command line to clean your project, and then try building again.

  3. Make sure that you have a stable internet connection, as the build process may require downloading dependencies from remote repositories.

  4. If you are using any external libraries or dependencies, try removing them and see if the build works without them. You can then re-add them one by one to see if any of them are causing the issue.

  5. If none of the above steps helped, you can try invalidating the cache and restarting Android Studio. To do this, go to File > Invalidate Caches / Restart.

Failed to transform library

saramarz
You have an issue "library-0.14.0.aar" in your Android project.

The build is unable to resolve or find this dependency, which is causing several tasks to fail.

There are a few possible reasons for this issue:

  1. The repository or location where the dependency is stored may be down or unavailable. In this case, you may want to try again later or check with the repository maintainer to see if there are any known issues.

  2. The dependency may have been removed or replaced in the repository. In this case, you may need to update your project to use a different version of the dependency or find an alternative solution.

  3. There may be a problem with your build configuration or your project's dependencies section. You may want to double-check that the dependency is listed correctly in your build.gradle file and that all of your dependencies are up-to-date.
