Why do I get a deprecation warning in Android studio Electric Eel | 2022.1.1, despite the fact that I am handling it? This happens no matter what the problem is.
This is my code where I get a deprecation warning for WindowManager.LayoutParams.FLAG_FULLSCREEN:
public void fs(Window dialogWin) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
final WindowInsetsController insetsController = getWindow().getInsetsController();
if (insetsController != null) insetsController.hide(WindowInsets.Type.statusBars());
} else
dialogWin.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
And if I suppress the warning with a
#SuppressWarnings("deprecation");
I then get a Redundant suppression warning. The only workaround I found was to add
#SuppressWarnings({"deprecation", "RedundantSuppression"})
Silly.

With the first patch for AS Arctic Fox Jetpack Compose previews stopped working.
I'm getting this error for all previews - even older ones, which worked fine a while back:
android.content.res.Resources$NotFoundException: Could not resolve resource value: [some hex value]
Are here any quick fixes for this? Clearing caches and the usual stuff did not work.
EDIT:
Looks like the problem is not always present. Some preview started working, while other are still failing.
EDIT 2:
This is happening in dynamic feature modules, when there's a need for resources from the main module or painterResource() is being used (even is resource from the same module is to be displayed).
Same problem here with dynamic-modules project.
Inspired by above answer, I've made another temporary workaround while waiting for Compose team to fix this.
import androidx.compose.ui.res.stringResource as originalStringResource
#Composable
#ReadOnlyComposable
fun stringResourceSafe(#StringRes id: Int): String =
if (BuildConfig.DEBUG) {
val resources = LocalContext.current.resources
try {
resources.getString(id)
} catch (e: Resources.NotFoundException) {
"missing res."
}
} else {
originalStringResource(id)
}
This got fixed in AS Bumblebee, patch 2.
As a temporary hack workaround I did this to get past the error and preview the UI elements.
//import androidx.compose.ui.res.stringResource
fun stringResource(id: Int): String {
when (id) {
R.string.res_id -> return "Foo"
...
}
return "missing res_id"
}
After I updated Android Studio to 3.5, I am facing below warning whenever I build my Project.
Missing class: com.fasterxml.jackson.core.type.TypeReference
My project is using AndroidX. Here is the gist for my build.gradle(app)
https://gist.github.com/Arkar009/4ae5a05ff3435636bc605fee1fbdb050 . Can anyone know why this error occurs or alternative ideas to solve this error? Thanks in advances.
If you're super sure you will remember this line if you include Jackson later in your project, this does the trick (add it in your project's proguard-project.[txt|pro] file):
-dontwarn com.fasterxml.jackson.core.type.TypeReference
That class gets included somehow in the missing classes Set in R8 (I didn't go that far in R8's code), but you can skip the warning if you get that class in the list of patterns for "Don't Warn" rules (see com/android/tools/r8/R8.java):
List<ProguardConfigurationRule> synthesizedProguardRules = new ArrayList<>();
timing.begin("Strip unused code");
Set<DexType> classesToRetainInnerClassAttributeFor = null;
try {
Set<DexType> missingClasses = appView.appInfo().getMissingClasses();
missingClasses = filterMissingClasses(
missingClasses, options.getProguardConfiguration().getDontWarnPatterns());
if (!missingClasses.isEmpty()) {
missingClasses.forEach(
clazz -> {
options.reporter.warning(
new StringDiagnostic("Missing class: " + clazz.toSourceString()));
});
TBH, I was also bugged enough by this warning to get into R8, hope it helps!
I'm very new to Android and Kotlin so I may be getting something very simple wrong, but as far as I can see when I call BluetoothLeScanner.startScan() none of the possible callback methods of the ScanCallback class which I've created is ever called.
I've understood that at API level 23 & above just putting the location permissions in the manifest may not be enough so I've written code to handle that & am satisfied that my App has both COARSE and FINE location permissions
Here's my override of the OnScanResult method:
override fun onScanResult(callbackType: Int, result: ScanResult?) {
super.onScanResult(callbackType, result)
mScan = true
}
I've put a break point in each of the callback methods and when I hover over these breakpoints while the code is running, I see the message "No executable code found at line..." That's a pretty disturbing message (and I suspect is pointing to where the problem lies) but (a) how can there be no code there when everything builds OK and (b) what do you do about it?
Update on that: I think that message is a red herring. I've now moved the break points to elsewhere within the callback functions and I no longer see the 'no executable code' message. Looks like Android Studio lets you put a break point on a line with no actual code in it!
So we're back to the original question - why are we getting no callbacks?
Looks like this is now solved:
(1) I did find a setting on the phone as distinct from turning on Location. It was enable Bluetooth scanning. However it actually made no difference (2) What looks to have been the real issue is a misunderstanding of the meaning of the string which you pass to the ScanFilter Builder with setDeviceName(). There is a string in our hardware Bluetooth module which we're trying to scan for which is called device name, and I was scanning for that. When I looked instead for the Beacon advertising data, it found it.
Many thanks for suggestions (only 1 I think)
Giving permissions in the manifest is not the same as the app using it.
For ble you need to give the location and bluetooth permission. Then:
in the app(on the phone) browse your open apps
find your app and click the 3 dots in the top left
Click app info
Permissions
Toggle location to on
Also the following is a handy bit of code:
public void checkPermission() {
if (Build.VERSION.SDK_INT >= 23) {
if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && checkSelfPermission(android.Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
} else {
ActivityCompat.requestPermissions(this, new String[]{
Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION,}, 1);
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if (requestCode == 1 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
} else {
checkPermission();
}
}
Ps Be safe all
i came from Microsoft course on edx, the template 10 is not working even after installing the NuGet Package, it gives me this error while compilling:
Error CS0103 The name 'PropertyChanged_ViewModel' does not exist in the current context.
and with double clicking on it, it takes me to the DetailPage.g.cs and the error is in this function :
public void UpdateChildListeners_ViewModel(global::solarizer.ViewModels.DetailPageViewModel obj)
{
if (obj != cache_ViewModel)
{
if (cache_ViewModel != null)
{
((global::System.ComponentModel.INotifyPropertyChanged)cache_ViewModel).PropertyChanged -= PropertyChanged_ViewModel;
cache_ViewModel = null;
}
if (obj != null)
{
cache_ViewModel = obj;
((global::System.ComponentModel.INotifyPropertyChanged)obj).PropertyChanged += PropertyChanged_ViewModel;
}
}
}
}
i deleted those if blocks and the error disappeared and the app ran but without the Hamburger Menu, any idea on how to fix this ??
Please consider updating the Template 10 Visual Studio Extension to at least version 1.7 and the NuGet package to at least 1.1.2. Then, create your project using the Hamburger template and let me know if it works.
takes me to the DetailPage.g.cs
Those .g.cs files are auto generated, and you shouldn't be modifying them. I think a clean build here would solve this issue, (especially after you've upgraded to a new version of T10)
Need help to resolve an error.
Currently I am working on a migration project from visual c++ 6.0 to visual studio c++ 2005.
And during compilation, I am getting "Undeclared Identifier Error"
I am hearing pasting the code and error.
code
const SMbfIndexCash* GetIxCashed(const CPoint& ptIxBlock, const short nMbfID)
{
SMbfIndexCash* pCashFound;
for(int ixFound=0; ixFound<MBF_IX_CASH_SIZE; ixFound++)
{
pCashFound=&ElementAt(ixFound);
if(pCashFound->nAge<0)
return NULL;
if(nMbfID==pCashFound->nMbfID && ptIxBlock==pCashFound->ptIxBlock)
break;
}
if(ixFound==MBF_IX_CASH_SIZE)
return NULL;
}
Error.
1>c:\cm and nemesis\cm code\cm 8.16\cm
8.16.0.1\source\cmoslib\tile.h(466) : error C2065: 'ixFound' :
undeclared identifier
Thank you.
The ixFound is now local to the scope of the for loop.
you need to do something like:
int ixFound = 0;
for(ixFound=0; ixFound<MBF_IX_CASH_SIZE; ixFound++)
{
//...
}
//...
