i making an application ,there is an other app that i want to add to my project, it is a source code and i allow to edit and add to the app menu of my app , but i get too many errors and its not fixable.
remember: i don't want to create an other manifest.XML or add another icon to menu if i could fix the errors i would added them to app menu because its working in its own project, i want a new app install with my app.
1. is there a way that the installer install more then one app? it would hep a lot
if not perhaps you can help me fix it this way:
error:
i add the package(java files) of the app and i have access to its file, all the XML are added and if there is an error i tried to fix them, i didn't run the project because i was shore i get errors , i fixed all that i could but now i get an error like this:
now i think i have to import its R class but then , all of values are in the XML and there is no need to bring the R class:
its own R class with suggestion of android studio:
import com.softwaredownload.app.R and R is red when i run it:
Error:(75, 25) error: package R does not exist.
ops! why do i get error for my own package Java files ?! i also clean and rebuild and restart the android studio. i mean when i added them at the first place and i fixed the errors at the top of them was the green mark that there is no error.
also , all of the project files are added the proper way but they are not working like the source code, i mean all the XML files are edited and fixed.
No, you can't install another app in tandem with your own app
Remove all the.old.package.R-import statements from the top of your pasted classes
Rebuild/run the project
Android Studio will then suggest importing your own package's R.class. Accept this recommendation. This requires that you've copied all resources (not just the layouts) from the old app into your new app.
i fixed the error like this:
it is impossible for two app to add to one installer APK but i just edit them both and i added them to the project than i edited manifest.XML and add two icon to android menu.
2.there is no need to bring the R class , it was an android studio error that fixed.
I have been working my way through the Tab menu tutorial and have come across multiple errors. After doing some research on here I found the common solution was to change the Import android.R to import com.example.myfirstapp.R.
This is giving me the error that this file cannot be resolved. Can anyone tell me why I can't import this file? I have a hunch from researching on here that eclipse has not built the file, but I have no idea how to build it as I am new to coding as this is just a hunch and may be completely wrong.
package com.example.myfirstapp;
[Edit}
i have removed the "com.example.myfirstapp.R" and have CMD-SIFT-O to restore the imports but i still have the following errors.
You don't need the com.example.myfirstapp.R unless it is in a library. If it is in com.example.myfirstapp, remove it.
Also, trying cleaning your project and rebuilding it.
Make sure you don't have any files, pictures, etc in your drawable or assets folder with capital letters, spaces, or dashes. Just use plane old lowercase. Also, try to clean your project. Go to project > clean. Then restart eclipse. Hope this helps. Also eclipse won't reconize any changes in XML files without saving first. Make sure to save after you add a button, ect.
My friend created an android application using phonegap, jquery and facebook sdk in eclipse. I wanted to run the application in my computer. So I imported the whole project into eclipse. I downloaded all the necessary APIs. Initially I got a lot of errors, but I solved most of them.
Now I am stuck with just one error. And it is in the src/com.facebook.android./FbDialog.java file. One particular line
Drawable crossDrawable = getContext().getResources().getDrawable(R.drawable.close);
gives the error R cannot be resolved to a variable.
I have gone through a lot of similar questions on this website as well as other websites. I have cleaned the project innumerable times. The R.java file builds successfully. Also, my friend is not getting any error when he runs the same project in his laptop. So I don't think there is any problem with the coding part.
I am definitely missing some important setting or download. Please help. This one error is giving me a lot of headaches.
I am a new user her so cant upload a screenshot.
1st. res/drawable folders (ldpi, mdpi, hdpi) must contain an image named close, if not add it. I doesn't really mater, in order to overcome the error, in which of them the file exist.
But in order to use resourses properly see the Android documentation here
2nd. File FbDialog.java must have an import of the R.java sometimes the R imports get mixed with clean & built and instead of import your.package.com.R; it is included the import android.R;
Depending on the dependency libraries or related projects of main project the close file resource may be a part of an other library in that case you will need import that.package.com.R;. So if it is part of Facebook SDK then you will need import com.facebook.android.R;
I hope you get the logic of how R imports work.
Update: Lets force it to work, change line to:
Drawable crossDrawable = getContext().getResources().getDrawable(your.package.com.R.drawable.close);
Newbie Alert: while working on my android application my program was acting kind of buggy so i went to project, and did "clean." i reimported my R but for some reason all my other classes and xml files are giving me errors "Cannot be Resolved or is not a Field"
i've restarted my eclipse and refreshed and im still getting these errors. Help please!
I come across this error often as well. Here's how to fix it:
Check your xml layout files for any errors. Fix any you find.
Delete all the "import" statements on the .java files that has all the "cannot be resolved or is not a field" errors.
Clean. (Project -> Clean...)
Re-import needed packages (Source -> Organize Imports) (Control + Shift + O). If a dialog pops up, choose carefully!
Save.
Basically you need to have < your package name >.R imported if you are using layout files.
If you have recently renamed a package, that could have caused this. Fix all the import statements so that they import the correct R, < your package name >.R
This has happened to me a lot as well. I found that it was usually a problem in one of my xml layout files such as missing a closing carrot or something like that. Just double check your xml's to make sure that you didn't forget something.
I had this problem too and i realized I have imported the wrong R.
Way to fix this,
Delete the already Imported R
Press Ctr + Shift + O and choose the R.
Save
Repeat the process and choose another R if it still has error.
i was using Eclipse Helios but due to performance issues i changed to Eclipse Galileo and installed the ADT plugging, and added my sdk folder to Elcipse Preferences. Now R.java disappeared from all of my projects. How can i fix this, i did Project/Clean but that won't generate the files, there's nothing wrong in my xml and there's no out.xml in any of my projects.
Thanks in advance
In my experience there is a mistake in the xml somewhere. Eclipse will no doubt tell you where. After I fix the error R appears.
Sometimes when you clean your project the R file disappears, I had the same issue.
The way I fixed it was:
-Make sure all the "import android.R" was removed
-Clean again (if this doesn't fix it, restart eclipse and try again)
Or
-Put the pointers to R file in comment f.e. // setContentView(R.layout.main);
-If all the pointers to R file are in comment, you should get only warnings in the file, and hopefully errors somewhere else.
-Fix the errors and then uncomment the pointers. Sometimes eclipse ignores some errors and drops the R file and then says nothing about it, which is annoying, but this will fix it. :)
-If this still doesn't work, you can try create a new project and copy paste your code in it.
I had this same issue today and figured it out. The reason this happens so often when including external/example files is because often times these examples reference layouts in your application, but do not have access to the package and therefore cannot see the R.java file in that package. to make things clear, here's the beginning of the R.java file:
/* AUTO-GENERATED FILE. DO NOT MODIFY.
*
* This class was automatically generated by the
* aapt tool from the resource data it found. It
* should not be modified by hand.
*/
package com.conceptualsystems.dashboard;
public final class R {
public static final class attr {
}
public static final class drawable {
public static final int csc_logo=0x7f020000;
public static final int icon=0x7f020001;
}
public static final class id {
public static final int activation_code=0x7f070012;
public static final int alpha_bar=0x7f07000b;
public static final int alpha_label=0x7f07000a;
notice the package name is whatever the package name of your application is. .java files that are not included in this package (ie, your example code you just dropped in) will need to explicitly reference that package file like this:
package com.example.android.apis.graphics;
import android.app.Dialog;
import android.content.Context;
import android.graphics.*;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.SeekBar;
import com.conceptualsystems.dashboard.R;
the last line is the one to pay attention to. after importing the resources explicitly, the resources will be available in your example code.
created new project in eclipse, then I imported the sample files into it, yet still same error. You might want to try the following:
In Eclipse -> Right Click on Project -> Android Tools -> Fix Project
made sure that all resources are lowercase.
Try unclicking and re-clicking build project automatically in the project dropdown, closing the program each time. There have been know bugs about this for a while but there's not always a set fix.
When it once happened to me it turned out it was because i'd named an .xml file with a capital letter. Worth checking.
I had this problem when upgrading from Eclipse/Helios to Eclipse/Juno.
I set up the IDE and then imported an existing (working) project. If I then ran it in the emulator it ran but in its original version although the java code was for the latest version.
I then did a Clean (as explained in many other posts) and a (re) build but then ended up with host of errors due toSmissing R.java file.
The problem turned out to be some 'errors' in the layout xml files which had not been recognised by Eclipse/Helios. Specifically, in my case, there were some layout_width='match-parent' (and height) settings which Juno objected to. I tried changing those directly in the xml files but Juno wasn't having it and still reported it as a 'match-parent' error (although it had clearly been changed).
The only thing to do was to go to the graphical layout, right-click to get Properties and then change the Width and Height properties there. Also, as they were already showing as 'fill-parent', I had to first change them to 'wrap-content' and then change them back to 'fill-parent'.
Once I'd done that for all instances of 'match-parent' I could then do a build and run the latest version in the emulator.
There are mistakes in res. Once I have the same xml files in layout and menu, generate failed, no R.java generated.
Localize the correct R. package import, should be in your packages.
ex. import com.yourdomain.test.R;
This is where ADT Android project is a bit different from a normal Java project. An android project requires a constantly updated persistent R.java file. Among other things, the R.java file has all the resources IDs provided in your App and maintains interface's consistency.
So first make sure R.java file is being generated for your android project.
To find that out first go to the top of ADT (Eclipse) and clean the project PROJECT->CLEAN
If the 'Build Automatically' is checked the R.java file should be created now.
To confirm, you can simply search the file in the project folder. You won't find it if its not being created.
If R.java is not being created, there is 90% chance that there is some issue with one of your interface *.xml files. Which usually resides in res->layout->activityXXXX.xml
Fix the interface file/s (try making it very simple with a single button or something) and R.java file will be generated by ADT automatically. At this point you should start noticing R.layout.XXXX not found type errors in your main program/activities. Which is a good thing, because now you can create/rename correct layout items and fix your project.
Just my 2 cents....
same happened to me, corrected checking any errors in res xml files, and changing target 1.5 to 2.2 android (on my case)
this usually happens to me when importing external code or online source code from examples or other developers.
Hi I had this happen to me this weekend.
The actual reason this had happened was that I had unchecked the update option for Android in the preferences as it wasn't working with the previous version of Eclipse. Now although the eclipse was seeming to run fine, when I PROJECT->CLEAN the project the R.java was missing.
Try re-ticking the android update option (WINDOW -> PREFERENCES -> INSTALL/UPDATE).
This completely solved my issue and I did not have to both with any hassle of scanning each line of my many xml files or my image resources.
Hope this helps someone :)
I just Encountered the same problem.
Turned out my Source control had inserted an Addedd>>>>>>>>>>>>>>>> section to my mainifest file.
All I had to do was fix the manifest file and then all the errors disappeared.
This happened to me while adding some new resources to my project.
The R file is build after every resource update.
The error in my case was incorrect file name. One of the image resources had a capital case letter in its name and that prevented the build from creating the R file. Changing the name simply worked.
I would suggest that when you add too many resources at a time, just make sure of the naming conventions for them. Its easy to miss such things.
Resource conventions: http://developer.android.com/guide/topics/resources/providing-resources.html
I had the similar problem. That was because I saved a drawable file picture.jpg as picture.png, as soon as I changed the name to previous one it started working. hope this would help someone in future
