I am trying to use the following code
https://github.com/harism/android_page_curl
I selected Create Project.Use the current source. Pointed it to the directory and click on Run. Following are the errors I am getting. Any idea ?
Try cleaning and building again. If not, it's likely that Eclipse is not recognizing your Android SDK install location. Check it under your Android preferences.
check this out 'Must Override a Superclass Method' Errors after importing a project into Eclipse
i would be willing to bet its the same issue, you can post some code but i dont think the #Override is there for the methods indicated in the error picture

My current setup :
OS : windows 7
IDE : Android Studio (with updated SDKs)
Parse jar (v 1.10)
I am trying out an example for ParseQueryAdapter, and I run into this error on my IDE : import com.parse.ParseQueryAdapter; -> cannot resolve symbol ParseQueryAdapter
I want to try something similar to this example, and the import does not seem to go through because of the error.
If you need anymore information, please leave comments & I will respond.
PS : I am able to add com.parse.ParseObject without errors.
In your libs folder you'll find Parse-1.4.1.jar file.
Right click or control+click on it then 'Add as Library...'
Edit: Parse-1.10 does not have ParseQueryAdapter. You have to use Parse-1.4.1, which is included in that example.
ParseQueryAdapter was removed from the official Parse SDK and moved onto the Parse-UI libraries..
You can install them on via this link: https://github.com/ParsePlatform/ParseUI-Android
If we include 1.4.1, and keep 1.10.1 as well, it gives error because we cannot keep the same jar with two versions in the libs folder. And I think its not advisable to use just 1.4.1. I feel that ParseQueryAdapter is deprecated and we would just have to use the normal adapters. Any comments?
I've found out that my R.java is never created. I'm using Android Studio and rebuilding does not solve the problem as well.
As far as i can see i don't have any mistakes in my XMLfiles as well.
I'm using W7. The error cannot resolve symbol R resolves.
Please help!
Code can be found here
I have created a new project and copy-pasted your code and it works fine (in Intellij IDEA 12 at least). I have dropped the line (this one android:theme="#style/AppTheme") with theme because you haven't provided code for your theme.
If you haven't added any gfx or other files and you're absolutely sure about the correctness of you theme style, then try to create a new project and do the same I did - code copy & paste.
If you have an error on your any code. No clean/build works to build R.java.
Just check your whole codes fix errors manually (Because of R.java is not builded it will show errors everywhere. So you have to find and fix errors on your own.)
It's usually due to an unaccepted character in the resources names, check for dashes, spaces and caps and let the project refresh
I already tried all the answers present in this website. Deleted the "import android.R;" line. Even then every time I run my project it says "Your project contains errors, fix them before running your application". I'm working on Eclipse. As soon as I create a new android application project I am encountered with 2 errors which say “R cannot be resolved to a variable”. Here's my code for MainActivity.Java
package com.example.myfirstapp;
//import android.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentViewq(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
just try this at your imports
import your_packgae_name.R;
If you are getting same problem when creating new project then the problem is with your SDK Version.
Update your SDK to rev. 22.0.1
After updating you will find new tool in SDK manager that is android SDK build tools.
thn install that tool also.
Hope this will help you.
Right click on the project's folder and then, Android Tools --> Run Lint - check for commons error. When this don't work, disable automated build, clean projet, run lint again --> build.
Ah also, in the proprierties -> Android, verify that build target is checked...
Delete the imported android.R (As what you did)
Re-import R
Eclipse will allow you to choose which should be imported. Choose the R from your package.
I had the same problem.
The R.Java was not generated(in the gen folder).
There was no error in the xml file.
The issue was that I did not update the sdk completely.
In the SDK manager we need to install the package whenever the "install(number) packages" button is enabled
and close and open the sdk manager to check for updates.
Close and reopen eclipse and check for updates in eclipse also.
Make sure this line,
setContentView(R.layout.activity_main);
in your code it contains "q".
Then build your application and then run
One of your xml files might have errors. Hence, R is not generated. Fix them and R will be generated and the errors will be removed.
Check if file "R.java" exists in folder "gen"
When aapt can not compile the resources, the R class can not be created. Look for errors in the resources of your Application.
More output you can find in the ErrorLog and Console window
(Eclipse Window menu->show view->Console (and choose "Android" in Console popup menu)).
check your drawables and make sure there is no file with capital letters to avoid error!
.
Did you start the project a while back and recently it has done this when you went to work on it? I had the same issue and recently came to find an answer. It could be that the problem is you need to go into the SDK manager and install a particular update as per the answer to this question: Eclipse error: R cannot be resolved to a variable
Try this once
Go to Project
Check Mark "Build Automatically"
and Restart Eclipse
Okay so I had the same problem, and I also tried everything:
Check for bad naming, remove the import statement, installed the Android SDK Build-tools, check the AndroidManifest.xml, reinstall eclipse and android SDK etc.
nothing worked.
And I was even working with a completely blank project (new -> android project)
I then found out that the android SDK comes with an already zipped eclipse, so I thought I might as well try that one.
So I uninstalled eclipse 64bit, and used the one which comes with the android SDK (http://developer.android.com/sdk/index.html#win-bundle) and now I dont get the error anymore, so give it a try.
I also found that using eclipse 64bit with a java 32bit version might cause problems. So it might be that the one that comes with the Android SDK vertion is the 32bit eclipse.
Hope this helps.
The problem was caused by incompatibility of version. Here are the steps to fix the problem:
Right click the project properties.
Select Android
Select correct Project build target.
I fixed mine.
I found this way working Awesome. Which is also slightly similar to Mr.AndyFaizan,
Check any of your xml files have errors or not.if yes R might not generate.
2.Fix the error at XML files. Then R will be generated automatically
Then import the R which is suitable for your package.
YES, your error "R cannot be resolved" Gone!!
if this error occur immediately after create your project on eclipse. the main reason is manifest.xml error.
application icon path is wrong. copy ic_launcher.png into drawable folders.
I've just installed the SDK and all the stuff necessary for programming Android in Eclipse for the first time, and I've just find my first problem. After opening a sample project (Snake, for 2.2), there seem to be errors in the code. Well, the R library was not imported. I don't get why it was not already there, but I've imported it. All good? Nope! text = getString(R.string.tie);still has an error. Same with the rest of code (when it uses R). tie is not recognized, it's not shown in that usual blue of Eclipse.
Eclipse says that the problem is ADT 14... final stuff, or switch statements. Ok... I've read that. There's no switch there. That's not the problem. Eclipse suggests me to change .tie to any other thing... like button1. That's not useful, of course. I think the problem is R class, not ADT. Or maybe R class has some final statement so it is not accepted.
I've tried to see if it was that and, in opening the R.class, I get this message: "The source attacement does not contain the source for the file R.class." What now?
R is not a library, it is a resources file, which is generated automatically during the build from existing resources. Just make sure that resources are properly placed where they belong. Then build the project and everything will be OK.
try using project-->clean in eclipse.
if you imported R library remove it. and try again
Make sure you have the required package installed in the AVD Manager. Then, check your Problems view in Eclipse and look at all other errors, other then the R-related ones and make sure everything else is fixed first. If you have an error anywhere in your XML layouts for example, R will not generated.
I am working on the Bluetooth Chat from the Android Developer site in
Eclipse IDE. I am using Android 2.1 and changed the Action Bar to
display Toast messages instead and am only working with Secure
connections.
I have three classes under the same package called BluetoothChat,
BluetoothChatService, and DeviceListActivity and the project name is
BluetoothCh.
Two of the files had errors that I fixed. They were saved and are
clear of the red x that previously marked both .java files. All of
the other files are clear of errors as well. However, the main
Android project folder still contains a red x, and Eclipse is not
allowing a run or debug of the application because of errors in
the project.
Does anyone have any ideas how to solve this? Any advice is very much
appreciated! Thank you!
Refresh the project then clean the project.
Delete the error in the "Problems" tab.
Right click the project->Android->Clean project properties (or whatever it is).
Clean the project and rebuild it see if the X mark still persists.
"When I clean the project it now gives me errors that R cannot be resolved as a variable. Where should I go from here?"
It sounds like you have an error in your code somewhere. You need to find out where the error is (what file and line) and fix it. This can be done with the problems tab in eclipse. It should tell you the description, file, path, line, and type of error you are getting.
