I getting
Error:(7) Error: Duplicate id #+id/item, already defined earlier in
this layout [DuplicateIds]'
I'm using Android Studio. How can I fix it? Thanks in advance.
If you using text layout and check the xml code for finding the red line(indication of error) in android studio.
If you have than change the value like shown in the image and finally clean and build the project.
Error Image
After change the id
Maybe you had defined two view with the same id.Check your code.(ctrl+f)
It is not the as's fault.

I created a sample Xamarin project and tried to convert it to Maui project using these steps(https://github.com/dotnet/maui/wiki/Migrating-from-Xamarin.Forms-(Preview)) but it is showing an error:-
error CS0579: Duplicate 'global::Android.Runtime.Resource DesignerAttribute' attribute
enter image description here
I was able to solve this issue by removing a lingering Resources\Resource.designer.cs file. Also make sure to comment out everything in Properties\AssemblyInfo.cs
I want to make a settings activity for an android app. I used the standard activity for the settings but I keep getting the error:
\.gradle\caches\transforms-2\files-2.1\e3ce7e7cf0568bf54350349961cc10db\preference-1.1.1\res\values\values.xml:257:5-336:25: AAPT: error: duplicate value for resource 'attr/defaultValue' with config ''.
I think it has something to do with the androidx.preference.PreferenceFragmentCompat because the error disappears when I remove the dependency on android.preference:preference:1.1.1. Do you know how to fix this?
I figured it out. The DevaultValue was already defined by me in the res/attr/ folder. deleting this value makes it work.
If you already have a field with defaultValue in attrs file, rename it and try rebuild it. It works
When I changed my package name and rebuilt the project, Android Studio put before many class names this string _root_ide_package_.com.example.<myprojectname>. And I have this error Unresolved reference: _root_ide_package_. Any ideas how to fix it?
While posting a code example would help, I had a similar issue and resolved it by doing a Replace in Path across the source tree and replaced all instances of _root_ide_package_.com.example.<myprojectname>. with nothing.
Just remove anything before the class name, for example:
_root_ide_package_.com.<project_name>.APP
Remove _root_ide_package_.com.<project_name>.
I'm getting the error executing aapt :return code 1073741819 due to which
.apk file is not generated how to fix this. How to fix if r.java file is missing
It could be a syntax or formatting error in one of the XML files. I just got this error code (it's actually negative), and I checked all the #string references and they were OK. Eventually I figured out it was because of this item in a menu XML file:
<item
android:id="#+id/action_stop"
android:orderInCategory="100"
android:icon="#drawable/ic_action_stop"
android:showAsAction="ifRoom | withText"
android:title="#string/action_stop"/>
However, the spaces around the | apparently aren't valid (XML isn't Java...). Eclipse didn't catch it as an error, but aapt crashed without giving a reason when it saw it. Not particularly graceful handling, by both Eclipse and aapt. Removing the extra spaces made everything work.
The problem with missing entries in strings.xml apparently produces error code -1073741816, not -1073741819. You have to look closely, but the last digit is different.
I'm not saying the problem is definitely some sort of syntax error. But it's another possibility that could be investigated.
I got this error when I had deleted a #string entry that was being referenced in a menu node xml resource.
I had this error and spent time trying to find a solution.
Finally the solution for this error which is: -1073741819 ( check the digits ) was a library was missing from: Properties -> Android -> Library
I just added the missing libraries and got this error resolved.
I got the same problem. What helped me was changing the Project Build Target
Properties->Android->Project Build Target
I am trying to use datepicker in my project. But as soon as I run the project, it throws "Resource not found exception" and following line appears when I drag datepicker in xml file
The following classes could not be found:
- CalendarView (Change to android.widget.CalendarView, Fix Build Path, Edit XML)
- DatePicker (Change to android.widget.DatePicker, Fix Build Path, Edit XML)
logcat entries are as follows:
FATAL EXCEPTION:
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.dateandtimepick/com.example.dateandtimepick.MainActivity}: android.content.res.Resources$NotFoundException: String resource ID #0x16
How can I rectify the code. Thanks in advance.
android.content.res.Resources$NotFoundException: String resource ID #0x16
You are trying to set int value in
tetview.setText() or Toast.makeText(), which it will take as string resource id.
So try to give int value in like this
.setText(""+intvalue) or Toast.makeText(context,""+intvalue,..)
I solved the "Resource not found" exception by re-installing the Android SDK. For some reason, while packing the apk, the SDK tools weren't packing the resources. Its' a build error (silent error) that yells only at runtime. I did not need to reinsatll JDK or eclipse.
Try to clean to Project to rebuild the R.java
Rebuild the xml by creating a new xml,I guess maybe you forget to add the namespace (xmlns:android="http://schemas.android.com/apk/res/android")
Hope I can help.
