Where is the R.java file in Android Studio? Can someone please help with this? I already tried google for the answer but can't find any solution.
Based on the new stable release of Android Studio (3.6) we have:
So, now to find your generated resource classes you need the following steps:
1) Open your project.
2) Go to your module build path.
3) Open the outputs/apk/debug/app-name-debug.apk file.
4) Choose your classes.dex file.
5) Look at the down placed area and go to your full package path.
6) You can see all bytecoded resource classes. So, scroll down to what you are looking for.
7) Expand the resource class you need to proceed (for example, let it be R.id)
8) Go to you id's.
That's it.
UPDATE:
If you would like to see actual id integer number you should follows steps below:
1) By (7) Go to the resource class you need to proceed and right click to show the context menu
2) Choose "Show Bytecode" to see the flexible dialog "DEX Byte Code for R$id", for example, for id class
3) Scroll down to the actual id to look its number
Although the current Android Gradle Plugin doesn't generate a R.java anymore you can still inspect the corresponding class file (see Sergey V.`s answer).
However, if you (like probably in most cases) just want to look up the generated IDs for your resources, there is an easier way:
In the project pane on the left hand side switch from Android to Project view using the drop-down at the top. Then navigate to app/build/intermediates/runtime_symbol_list/<insert build type here>/R.txt. This file lists all IDs generated by AGP during the build process.
I use Android Studio 3.3.2
\app\build\generated\not_namespaced_r_class_sources\debug\processDebugResources\r\android\support\constraint\R.java
As noted above, "The new Android Gradle Plugin generates the corresponding bytecode directly and does not make the intermediate R.java file".
Using the ubuntudroid solution you can find an id also this way. Find R.txt and copy absolute path. Project > app > build > intermediates > runtime_symbol_list > debug > R.txt. Then right click and select Copy Path..., 1. Absolute Path Ctrl+Shift+C.
This way you will obtain a path to R.txt, for instance, "C:\Users\user\AndroidStudioProjects\your_project\app\build\intermediates\runtime_symbol_list\debug\R.txt". Copy the path without R.txt to a text file for future references, for example, with Notepad++.
Press Ctrl+Shift+F to find in directory. Insert an id and the path.
== Old answer ==
Change a project view from Android to Project or Project Files. Find one of these two files.
Then you can revert back to Android view.
I use Android Studio 2.3.3. The R.java file is shown in the picture above.
In the left upper side, there is a select list. Select the [project] option so that you can see all the folders and files.
R.java is the generated file by ADT or Android studio. It will be located under app\build\generated\source\r directory.
./app/build/generated/source/r/debug/android/support/v7/appcompat/R.java
./app/build/generated/source/r/debug/your/packagename/name/R.java
I am using Android Studio 2.2.3 , the R.java file is shown in the picture below.
Goto in the left upper side there is a selecting list ,
select [package]
Open "App Folder"
com.example.saeedanwar.myapplication;
r
In my project in Android Studio 4.1
R.jar that you can actually unzip resides in app build folder, as follows:
jar -xf R.jar
Once the jar is unpacked you can find R.java inside of app package:
If you're using Mac or Linux, try the following command line on your terminal:
find . -name "R.*"
It will print something like:
./app/build/intermediaries/runtime_symbol_list/debug/R.txt
./app/build/intermediaries/compile_and_runtime_not_namespaced_r_class_jar/debug/R.jar
It is inside app\build\generated\source\r folder
Project/app/build/generated/source/r/debug/com.android.'projectname'/R.java
--The R.Java that contains your xml layouts and views id's in Android Studio 3.5.3 -- Project/app/build/generated/not_namespaced_r_class_sources/debug/r/com/"your package"/R.java
This answer will be in a constant state of flux until Android standardize a method of matching their annoying decimal/hexadecimal id references to a tangible resource such as my_layout.xml.
For Android Studio Dolphin | 2021.3.1 Patch 1 have a look at this file:
/project/package/build/intermediates/stable_resource_ids_file/debug/stableIds.txt
It is produced by RUN (not just BUILD). Sample:
layout/mtrl_picker_header_fullscreen = 0x7f0d00de
string/cancel = 0x7f1101f0
style/ThemeOverlay.MaterialComponents.MaterialCalendar = 0x7f1202f3
id/gpxBtn = 0x7f0a0346

There may be 2 cases(As far as I know),
You have tried to convert image type just by changing their extensions.
Your project location is too deep.
We can discard 1st option as you have already said that you don't have these images.
For 2nd option, try to move you project in root folder (c:\project or d:\project) & manually delete your intermediate folder & then build your project again.
Hope it helps
I'm programming an Android app that uses Gradle. However, in the .xml files and Android Manifest, the URL for Android Schemas are "Not registered".
This problem has been a nuisance and have spent hours trying to get it fixed. I have looked through:
1: Intellij Android project schema URI not registered?
2: If I change an external library: AndroidManifest, cannot parse file
I cannot just create a new project because this application is not only developed only by me but a small team. The code is also on GitHub as well. Secondly, even if I try to create a new project, the Schemas are still not registered.
Eclipse is not an option because they do not officially support Gradle integration. (unless you have found a Gradle plugin that is SPECIFIC to android applications). I also have installed Android Studio, but I still get the same errors, if not more errors.
Edit: I am currently using Intelli-J community edition
I had almost the same problem, 2 different flavors and that URI error in the xml files inside one of the flavors. I've solved by placing a copy of the Android Manifest inside the folder of the flavor that was giving me trouble, build project and error gone
For me the only thing worked was add mock Activity with right click on the Flavour package, choose "new->activity>empty activity", choose the fit source set and package name in the dialog, and after the Activity created the problem solved. I deleted the mock activity later and it not brought any problem.
Combining both Hernan Romero's answer and yshahak's answer, create an Android Manifest file inside each flavor's root folder.
For example, if you have a flavor called "pro", right-click on the pro folder then choose new * other * Android Manifest File.
(I did it the "long way": for each flavor, I set that flavor to be the active variant and then created a dummy empty activity with no layout file. I then removed the activity and unneeded xmlns: from the manifest and then deleted the activity and now-empty java folder in the flavor's folder. Rinse-repeat for the other flavor(s). That left me with an almost empty manifest, for each flavor, as follows:)
My "dummy" AndroidManifest.xml file in each flavor contains only:
<manifest>
<application/>
</manifest>
ShowcaseView is contained in a Zip file here. But what exactly am I downloading and how do I import it in Eclipse?
After 2 days I succeed, I have created steps to import ShowcaseView in Eclipse that may be helpful to you.
How to use Showcase View in Eclipse.
Download ShowcaseView from github and extract.
Now Follow step for import.
- Right click on Project Explorer
- Import -> Android -> Existing Android Code Into Workspace
- Select Extracted "ShowcaseView-master"
- Check both project "library" and "MainActivity"
- Check "Copy projects into workspace"
- Finish.
(After importing you can see 2 projects imported namely "main" and "SampleActivity", you may change "main" as "libShowcaseView" and "SampleActivity" as "ShowcaseViewDemo" so you can easily identify. :) )
May you see error in "ShowcaseViewDemo" (Dont worry...), See src/ folder is also blank (in both "libShowcaseView" and "ShowcaseViewDemo") :) right??? Dont mind.
Make following packages in "libShowcaseView" project. See Example.
- com.github.amlcurran.showcaseview
- com.github.amlcurran.showcaseview.targets
and Move all java files from /java/com/github/amlcurran/showcaseview and /java/com/github/amlcurran/showcaseview/targets Respectively.
Make following packages in "ShowcaseViewDemo" project. See Example.
- com.github.amlcurran.showcaseview.sample
- com.github.amlcurran.showcaseview.sample.animations
- com.github.amlcurran.showcaseview.sample.legacy
- com.github.amlcurran.showcaseview.sample.v14
and move files as above (from java folder respectively).
Now right click on "libShowcaseView" project->properties->Android->Move down and check "Is Library" then add "actionbarsherlock" as Library. See Preview
Now Add as library in ShowcaseViewDemo. Goto properties of "ShowcaseViewDemo"->Android->Add->select "libShowcaseView"->Ok...
I think you didn't ran into error now. You can Run.
You can ping any time for any suggestion or help.
Happy ShowcaseViewing...
Easiest way is:
Create an empty Android Application project in your Eclipse workspace.
Copy files in ShowcaseView/library/ folder of github to your new project base folder.
Refresh project in Eclipse.
Goto project properties - Android and select "Is Library"
Clean unnecessary stuff and build.
It should be ready to add as dependency of your app.
Alternatively you can pick another library project .project file and copy it inside this library folder, edit it to match your new project name, etc... And then import in Eclipse. But this is more hardcore if you don't know what you're doing.
Soure : How do I build these libraries from GitHub
Following ツ Pratik Butani ツ's Answer and use Android Support Library to replace ActionBarSherlock
In project.properties of libShowcaseView and ShowcaseViewDemo
add target=android-21
Right click on "libShowcaseView" Properties->Android->Library->Add... select AppCompat(android support library v7)->Ok
In styles.xml of ShowcaseViewDemo
Change
android:Theme.Holo.Light, Theme.Sherlock.Light, Theme.Sherlock.Light.DarkActionBar to Theme.AppCompat
Remove <item name="android:fontFamily">sans-serif-light</item> in ListItemBigText
In ActionItemsSampleActivity.java
change SherlockActivity to ActionBarActivity, getSupportMenuInflater to getMenuInflater.
In MultipleActionItemsSampleActivity.java
change SherlockActivity to ActionBarActivity
change com.actionbarsherlock.app.ActionBar.OnNavigationListener to android.support.v7.app.ActionBar.OnNavigationListener
changegetSupportMenuInflater to getMenuInflater
Do it in there steps:
Download ShowcaseView from github`
Create package com.github.amlcurran.schowcaseview and com.github.amlcurran.schowcaseview.targets in your eclipse project.
Extract ShowcaseView-master.zip or rar.
Go to library/src/main/java/ and copy com/github/amlcurran/showcaseview java files in com.github.amlcurran.schowcaseview package.
Do same thing for com/github/amlcurran/showcaseview/targets in com.github.amlcurran.schowcaseview.targets.
Finally, copy others files in differents folder drawables, layouts, value(copy in the old value files, style.xml for example).
I am developing an Android app using Phonegap and jQueryMobile, working in Eclipse. I want the app, with the user's permission, to auto-install a launcher icon on the user's "desktop". I've found the example LauncherShortcuts.java on Android Developers, and I am almost to the point of getting it to work. That's a big achievement, since I know extremely little of Java programming.
Almost.
This is the example code online:
http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LauncherShortcuts.html
One string or thingy in the code refuses to cooperate. Line 83...
TextView intentInfo = (TextView) findViewById(R.id.txt_shortcut_intent);
...has this constant or variable in it called "R.id.txt_shortcut_intent", and Eclipse says it doesn't recognize the id part. If I follow its suggestion of adding a class 'id' in R., it tells me there is no field txt_shortcut_intent in 'R.id'. That doesn't surprise me.
I've been able to fix a few similar errors involving R.something_or_other. But not this one. My R.java only contains the classes attr,drawable,layout, and string.
What is going on here and most importantly, what should I do to get this thing up and running? The launcher icon is all that stands between here and actually launching the app (how ironic).
If you find any errors in the project. Sometimes id of R.java entries will be shifted to string folder or R.java.
For this choose
project → clean
file → close all
click on your project
See the entries in id of R.java your ids will be in this folder
An android app uses an xml to define the layout of all the elements you want to display. In this case, you're missing an element that displays text called TextView. You don't have the Textview 'txt_shortcut_intent' defined in the xml, probably.
Here's the xml you're looking for (just copy and paste it into your main.xml):
http://developer.android.com/resources/samples/ApiDemos/res/layout/launcher_shortcuts.html
The ADT Plugin in Eclipse can only rebuild the R class if there are no (Java) errors.
Therefore, fix all errors and check if your layout ressource has the correct id (txt_shortcut_intent).
It's worth a try to clean the project and restart Eclipse.
I have just started writing my first ever Java/Android application, so forgive the total n00b question.
How do you access the the standard operating system icons such as search icon/menu icon etc? They are not in the res/drawable folder where I would expect to find them. Are they available as part of the SDK or must you download them seperately?
EDIT
Maybe you can help me further - I am getting the following error (repeated on):
[2011-09-08 19:59:47 - TweetTab] C:\Users\Dan\workspace\TweetTab\res\menu\options_menu.xml:4: error: Error: No resource found that matches the given name (at 'icon' with value '#drawable/ic_menu_search').
However, the icon is not empty, the xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/search"
android:icon="#drawable/ic_menu_search"
android:title="#string/search"/>
</menu>
Am I missing something?
SOLVED
I changed android:icon="#drawable/ic_menu_search" to android:icon="#android:drawable/ic_menu_search" and it could then find the icon.
You can acces them via android.R.drawable.* or in xml by #android:drawable/something.
I installed the Android SDK for Eclipse on Windows.
Now I can find all ressources under "C:\Program Files\Android\android-sdk-windows\platforms\android-9\data\res..."
try this instead:
android:src="#android:drawable/ic_menu_camera"
it is now possible to use vector assets to generate standard (or customised) icons for android.
Add 'com.android.tools.build:gradle:1.4.0-beta3' to your build.gradle file. (The stable version will be out in the coming weeks).
Add a vector asset by right-clicking res/drawable/ > New > Vector Asset. Android Studio provides a built-in viewer for you to pick your drawable.
Reference your icon like you usually do. Eg: android:icon="#drawable/ic_help_24dp"
A lot of them can be found in android.R.drawable but not all are publicly accessible
You can find the android.R.drawable images in your local SDK folder. (Tested using Android Studio 3.0)
First have a look at the docs for the names of the drawables here: https://developer.android.com/reference/android/R.drawable.html
Second either search your drive for one of those image names.png or type in the name of any of them into your Android Studio activity and right click (goto declaration) on it to view the image. Then you can also right click that image to copy the path. Then open that folder and look at all the PNG's there.
Example on windows 10: android.R.drawable.star_big_on is located in user/AppData/Local/Android/Sdk/platforms/android-25/data/res/drawable-hdpi/star_big_on.png
(Note also on windows AppData is a hidden folder so you may need to set your windows explorer to show hidden if you are clicking to open each folder)
Also if you need to see material design icons / descriptions this is a good place to look: https://material.io/icons
Someone may see this page useful for getting those icons... http://developer.android.com/design/style/iconography.html
For those of you in the Visual Studio/Xamarin Android camp, you can view and add the standard Material icons pretty easily using the following plugin:
https://marketplace.visualstudio.com/items?itemName=nikainteristi.Materialiconsgenerator
I've used it a few times in my projects.
