I see courses that use handler and runnable without importing it but when I use it gives me this error
enter image description here
enter image description here
I want to know how I import it to pass this problem or solve this problem without importing it
I dont think this is related to Runnable. instead go to Build.gradle(Module: Appname.app) and look for
namespace 'com.example.package'
compileSdk 33 // this should be 33 yours has it at 32
defaultConfig {
applicationId "com.example.package"
minSdk 21
targetSdk 33 // this should be 33 also has it 32
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

I don't want to skip this information all the time. Is there anything I can do to make it not appear?
I think it's when I store the images in the gallery or something from my android app.
Error lines
This does not affect the operation of the app as such but it is annoying that the logcat is overloaded with this.

So here is it

You have initialised the buttons and edittexts even before you have called the content view !
Initialisation should be done after setContentView();

I am currently working with an Android service:
https://developer.android.com/guide/components/services
I am creating a service that has to be a foreground service.
But looking at the documentation, a foreground service requires a notification channel.
But a notification channel is only on api 26 or higher. How can i create a notification channel for < 26?
I am stuck with this code
if (VERSION.SDK_INT >= 26) {
getSystemService(NotificationManager.class).createNotificationChannel(new NotificationChannel("ServiceWorker", "ServiceWorker", NotificationManager.IMPORTANCE_DEFAULT));
}
There is no way to create notification channels for API level < 26, because notification channels were added in API 26.
Fortunately, that means that your code is already correct. You're already doing the right thing by only creating the channel on API level >= 26.
When you create the notification with NotificationCompat.Builder, you can simply call setChannelId with your string unconditionally, and it will ignore it for you on Android versions where channels are not supported ("No-op on versions prior to Build.VERSION_CODES.O").
You can then pass the returned notification to startForeground, as described in the guide you linked.

I have to make an on screen keyboard for a swing application. In that I need to write text with different font size on the same JButton. I want to make keyboard like in smartphones.
for example:
jButton.setText(1(font size 30) ABC(font size 10));
As in the above example I want to set "1" with font size 30 and "ABC" with font size 0f 10.
Can anyone tell me how can I achieve this.
Thanks in advance.
Use HTML as text. Something like this:
button.setText("<html><font size=\"1\">small</font> <font size=\"7\">huge</font></html>");

So I got this bit of code http://pastebin.com/RMh4eHLq from the Android dev blog (modified) but when I try and call it via
ImageDownloader.download(image, image_main, image_table);
it tells me to change the download modifer to static but if I do that the ImageDownloader class tells me no portion is accessible. Any ideas?
Have you tried with:
ImageDownloader imgDwn = new ImageDownloader();
imgDwn.download(image, image_main, image_table);
