I was trying to create a new project for android wear in eclipse , but there is a problem in main layout i don't now how i can solve it , this is my main layout:
<android.support.wearable.view.WatchViewStub
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/watch_view_stub"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:rectLayout="#layout/rect"
app:roundLayout="#layout/round"
tools:context=".MyActivity"
tools:deviceIds="wear">
</android.support.wearable.view.WatchViewStub>
it is give me this error :
Multiple annotations found at this line:
- error: No resource identifier found for attribute 'rectLayout' in package
'com.example.wear'
- error: No resource identifier found for attribute 'roundLayout' in package
'com.example.wear'
my project have two layouts "rect.xml" and "round.xml" and it is compile with 4.4W and target is 4.4W and also i have a copy of classes.jar in libs folder .
The code you've posted is fine. The problem here is that you have a copy of classes.jar in your /libs folder, but this is not a right way to properly use wearable-support-lib. This wearable-support-lib contains some resources that cannot be packaged inside a .jar file, so you need to import it as a "Library project" and attach it to your project just like other external libraries.
You need to go back to the wearable-1.0.0.aar file, located in relation to your sdk folder:
./extras/google/m2repository/com/google/android/support/wearable/1.0.0/wearable-1.0.0.aar
Unzip the whole wearable-1.0.0.aar file somwehere to your workspace. You will see that it looks almost like a standard android project.
Move classes.jar to /libs/classes.jar - inside this project, not to your own project.
Now you have to create new project from these files, with package name defined android.support.wearable.
Compile it with API 20 and check "Is Library" in project properties in Android tab.
Add reference to this library project from your project.
You can see more details about using wearable-support-lib in my other answer and in this great blog post (by Benjamin Cabé).
I just added the following code in the dependency section in my build.gradle of the module:
compile 'com.google.android.support:wearable:2.0.3'
compile 'com.google.android.gms:play-services-wearable:11.0.0'
What worked for me was changing this:
xmlns:app="http://schemas.android.com/apk/res-auto"
To:
xmlns:app="http://schemas.android.com/apk/com.mydomain.myapp"
Where com.mydomain.myapp is the package id of my app.
Presumably the res-auto functionality was not working in my project for some reason.
I got this problem too sometimes, in my case i solved it by rightclicking on the AppCompat map then click on refresh, do this with your projectfolder too.
I put my apps in google play store,due to some reasons,its showing some error.Now i did those correction and i want to update the new apk,without reducing my older download numbers and their ratings and comments.Is this possible to update apk without reducing the older downloads
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ibetter.recipestutors"
android:versionCode="1"
android:versionName="1.1" >
To update your app, simply export a new apk and sign it with the same certificate as your origianl apk. Make sure you've incremented the version code.
Updating an app will have no effect on its download count. Your app will still have the same download statistics, and any users who still have it installed will receive an update notification via Google Play which will allow them to update the app.
You just have to increase your application version code in the manifest. But keep the same package name:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dont change the package name"
android:installLocation="auto"
android:versionCode="increase by 1 every time you want to upload new apk"
android:versionName="this can remain same but better change depending on the versionCode"
I had a working android project but needed to start from scratch. I copied all my source files and layout files over. There are no compilation errors but when I try to run, I get the following error.
11-27 17:21:56.793: E/AndroidRuntime(1450): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{projects.mobile.mapappproject/projects.mobile.mapappproject.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "projects.mobile.mapappproject.MainActivity" on path: /data/app/projects.mobile.mapappproject-1.apk
I am running eclipse juno and trying to run on Android 4.2. Thanks !
Rather than doing copy paste try following
1.Create an android application project
2.Delete the files which was created Eg.MainActivity and layout.
2.Right click on project name and click import ,then from File system.Go to your project directory to import the source from there
3.select that, then finish.
4.Clean and build then run
Try these
Add the Activity to AndroidManifest.xml
Is there a difference in your folder names ? For example projects.mobile.mapappproject-1 or projects.mobile.mapappproject !
I copied all my source files and layout files over.
It looks like you forgot to copy over the entries that existed in AndroidManifest.xml, however. Each Activity has an entry there and that entry is required for the framework to find and launch the UI.
I had the same problem, but I found out that a library reference path wasn't right. After I fixed that everything worked fine.
You can check this at Right-click on your project => Properties => Android -> (Library)
Just for the record in case I can help someone :
I had a project that somehow didnt work after importing it from git. I solved this by giving the name of the activity explicitly.
example:
before:
<activity android:name=".Main" [...] /> (relative)
after: <activity android:name="com.example.package.Main" [...] /> (absolute)
This may also occur if you change the manifest package and keep your relative reference (which I think is default).
In my case, following 2 steps fixed the problem
a. Setting compileSdkVersion, buildToolsVersion, targetSdkVersion to the same SDK version in build.gradle.
b. I was missing a dot in application class name in AndroidManifest.xml (Ex. android:name=".ui.ApplicationLoader")
I am currently developing an Android app using cordova 2.0. Obviously the plugins.xml has been depreciated and everything is now housed in config.xml. I was just wondering if anyone has managed to get the Phonegap Screenshot plugin working in Eclipse and Cordova 2.0 working on android.
Plugin can be found:
https://github.com/josemando/phonegap-plugins/tree/master/Android/Screenshot
I have added:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
to my Android manifest xml. And made sure that:
<plugin name="Screenshot" value="org.apache.cordova.Screenshot"/>
is added to my config.xml (that now contains all plugin information from plugin.xml)
Screenshot.js is added to the directory:
assets/www/js/
However I am unsure where exactly to place the Screenshot.java file. The example has it in:
src / org / apache / cordova /
However as I did not have this directory I simply placed it in:
src/uk.co..appname1.appname2/
When I did this however it produced errors, the first one being:
The declared package "org.apache.cordova" does not match the expected package "uk.co.mysitename.appname1.appname2" Screenshot.java /Project Name/src/uk/co/mysitename/appname1/appname2line 8 Java Problem
This refers to this line in the Screenshot.js:
package org.apache.cordova;
The two suggested actions to fix this are to:
Move 'Screenshot.java' to package 'org.apache.cordova' (this directory doesn't exsist atm)
Or change package directory to 'uk.co.mysitename.appname1.appname2'
The second error says:
The method run() of type new Runnable(){} must override a superclass method
The suggested action for this being to "remove '#override' annotation"
I have tried to do every possible combination of these however I cannot seem to make progress and get it all to link up. Usually because it thinks that CordovaRef isn't referenced. I am unsure if the plugin even works on Cordova 2.0.0. I have some experience with Phonegap/Cordova but only in ios with Xcode and Objective C plugins. I am new to Java, Eclipse and Android. Any help or clarification on any of these matters would be greatly appreciated.

This question already has answers here:
R cannot be resolved - Android error
(108 answers)
Closed 10 years ago.
So I copied this tutorial example thing right from Google's android site and I ma getting an error that R.id cannot be resolved.
Here is my Java file
package com.TestApp.HelloWebView;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class HelloWebView extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
}
Here is my res/layout/main.xml
<?xml version="1.0" encoding="utf-8"?>
<WebView android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
You have to import your R class
import com.TestApp.HelloWebView.R;
Also as Demand posted you have to use a namespace for your layout.
?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
I had the same problem when I updated my Android SDK. Suddenly new projects could not generate the R.java file.
importing my R.java didn't help because it wasn't generated
cleaning and building the project didn't help either -- the /gen folder was still empty.
I found that after the upgrade, the adb server didn't start up properly. So a manually started it:
$ cd $ANDROID_SDK/platform-tools
$ adb start-server
Then I restarted Eclipse and did a clean/build on the project, which generated the R.java file.
If using Eclipse, run a clean build (Project/Clean...); this can often clear issues with the resources not being compiled correctly.
Did you try any of the solutions listed here?
R cannot be resolved - Android error
Also, look for your R.java file. Are there any errors with it?
I had this problem too. I can't say a solution in general, but you can make a new workplace and copy the hardcode. In the future never click on clean or build, instead save or start eclipse again.
Go in your main.xml file, delete a char and rewrite it. That will generate the R file again.
On trying an Android beginner's tute (http://mobile.tutsplus.com/tutorials/android/android-sdk-development/) the "R.id cannot be resolved" error had me stumped too. In my case it was an android:onClick in /res/layout/main.xml. It seems onClick is not supported in AVD platform 1.5 API level 3.
A change to a new AVD with platform 1.6 API, level 6 removed the error - also started the project from scratch with the new api and level settings. For absolute Eclipse newbies (like myself) create a new AVD with:
Window -> Android SDK and AVD Manager -> New. Select platform, level number from "Target" drop down list.
Also try deleting the ~.android\debug.keystore (Happened to me, thought it was due to R.id issue). Real problem was debug.keystore was older than a year!
I ran into this problem when I tried to follow Lars Vogel's Android development tutorial...it turns out my problem is simply because I didn't save the layout file. Once I save the file, it works fine.
make sure you do not have any xml files with capitals in the name.
I had the same problem.
all the file names in res (and all its sub folders including layout) must be lower case only. This includes image files, xml files, etc (even if they aren't referenced anywhere within the project.)
if you posted full your main.xml file, then it's not right. You must write a namespace of xml:
xmlns:android="http://schemas.android.com/apk/res/android"
for example:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/label"
android:layout_width="78dip"
android:layout_height="65dip"
android:paddingTop="4dip"
android:textSize="12dip"
android:singleLine="true"
android:ellipsize="end"
android:textColor="#color/bright_text_dark_focused"
android:gravity="center_horizontal|center_vertical" />
Yeah another fix
I started the emulator. By running a helloandroid program, that did compile.
And got out of eclispe and got back in don't know which one fixed the problem..
Cleaning the project etc didn't fix it - can i have 2 hrs of my life back!
import com.TestApp.R;
isn't accepted once R is lost.
My Eclipse now auto creates a new "res" folder everytime I "clean". Yes, I have two folders named "res" in parallel directly under my project folder. The auto created one is empty. String values are still found. No other errors than "R cannot be resolved" are reported by Eclipse.
Eureka! I've managed to make my first android project import to Eclipse!
Earlier I always got "Unable to find system library" under the project's Properties - Java build path - Libraries tab and it was impossible to correct it once it occured. The consequence was that no import statements could be resolved by anything imported.
In this case, I changed the JDK compliance level from 1.6 to 1.5 BEFORE I imported (afterwards its too late and cannot be mended). It must be done from Window - Preferences - Java - Compiler (earlier I thought this option was available only by right-clicking on already imported project). Then right-click on each project and set Properties - Android to a suitable Target (with the errors above, eclipse ignores any selection here). Then, I could even change back to JDK compliance level 1.6.
So, in general, changing the JDK compliance level before importing, might help.
And when deleting a project ALWAYS check the "Delete project content on disk (cannot be undone)" checkbox in the "Are you sure" dialog. Otherwise it is impossible to re-import the project, o if you've imported it with the wrong JDK compliance level the first time, it is impossible to correct the mistake, other than to try in another workspace.
These are the experiences of a very frustrated Eclipse user.
Make sure there is not a hidden error in one of your .xml files.
Sometimes you can delete a statement in the strings.xml file that is important.
For example, in the Vogella example, I got the error:
Error: No resource found that matches the given name (at 'title' with value '#string/menu_settings').
I had deleted the line:
<string name="menu_settings">Settings</string>
Putting this back in or deleting res/menu/main.xml would solve the error.
I had the same problem but got fixed
i dont know exactly how this problem gonna fix
Just try, It might be helpful
add this code at the top of ur code
import com.MyFirstApp.activities.R;
here com.MyFirstApp.activties is my component name replace it with your component name
