I'm trying to implement the new v7 Support Library ActionBar. However, I can't get it to run properly.
Here's the exception

The problem happens at the super.onCreate(bundle) call at onCreate().

So, how I solved this problem:
Import support library as a project from "sdk/extras/android/support/v7/appcompat".
Reference library in your project (for Eclipse, "Properties - Android - Add").
Build projects (for Eclipse, "Projects - Build All"). Make sure, you have "android.support.v7.appcompat" in your main project gen folder.
If it doesn't worked - clean and rebuild project.
I have done the following and worked for me.
Delete the jar from the libs folder.
Import the sdk\extras\android\support\v7\appcompat\ project in your eclipse workspace.
Ensure that the android-support-v4.jar is the same in your project.
Add the appcompat as a library to your project.
Ensure that your in yout Manifest.xml your activity has the correct theme
<activity
android:name="***.*****.******"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat.Light"
>
Good Luck ;)
In addition to BoredT's answer I added this line to res/values/styles.xml
<style name="AppTheme" parent="#style/Theme.AppCompat.Light">
Follow steps from Adding libraries with resources -> Eclipse http://developer.android.com/tools/support-library/setup.html :
follow all the steps (use copy project in workspace)
add android.library.reference.1=../android-support-v7-appcompat to your project.properties
use android:theme="#style/Theme.AppCompat" I used it in application tag you can apply to individual activities as well
Rebuild all!
I think you should change your target version to 18 in the manifest.
android:targetSdkVersion="18"
This is how I solve the problem: rebuild the adroid-support-v7-appcompat library project in your eclipse workspace. Then build your own project again.
How to import a project as a library in android studio? Follow the tips blog as a reference:
http://showlabor.blogspot.com.br/2013/05/actionbarsherlock-in-android-studio-01.html
The next question, also helped a lot:
Error implementing Support Library Action Bar
The following image shows the structure of the imported project. That is copied to the root of my project and placed in the directory 'libraries':
https://dl.dropboxusercontent.com/u/67269258/Tuto/tree.PNG
In addition to mounting the above structure. In 'settings.glade' I had to add the new project:
include ':FreeMusic', ':libraries:ActionBarCompat:appcompat'
Inside the library project, added the file 'build.gradle'
It is located in: libraries/ActionBarCompat/appcompat
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}
}
apply plugin: 'android-library'
dependencies {
compile files(
'libs/android-support-v4.jar',
'libs/android-support-v7-appcompat.jar'
)
}
android {
compileSdkVersion 18
buildToolsVersion "18.0.1"
defaultConfig {
minSdkVersion 7
targetSdkVersion 16
}
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
instrumentTest.setRoot('tests')
}
}
In 'build.gradle' (internal project) of my project.
dependencies {
compile project(':libraries:ActionBarCompat:appcompat')
}
In android manifest added the necessary theme:
<activity
android:theme="#style/Theme.AppCompat"
android:name="es.hol.soundmedia.MainActivity"
After all this work. Perhaps an easier way to set this up, but for me the account is working.
Unfortunately I can not show the result, because I'm being blocked, but I hope the instructions help.
For those that don't like needing manual user effort in Eclipse in order to do a build from checkout, the magical change that Eclipse makes is to add a line to project.properties like:
android.library.reference.1=../android-support-v7-appcompat
This is enough to build your application from ant. You can do this in the source yourself, or via the Eclipse user interface - either way you can check it in to your version control system and successfully build from a fresh checkout of the source without requiring manual steps.
But you can instead make the path a sub-directory of your own project if that suits better, E.g.
android.library.reference.1=android-support-v7-appcompat
... and ...
cp -r $SDK/extras/android/support/v7/appcompat android-support-v7-appcompat
Note that Eclipse will still show various warnings until the sub-directory is also added [manually!] to Eclipse's workspace as a project. But an ant build will successfully build without using Eclipse.
Check for R.java for appcompat v7 jar is present in your generated folders of your application

I followed a tutorial of new component NavigationView in Support Design Library and can't get through this error message :
Error inflating class android.support.design.widget.NavigationView
I tried every workaround here

StackTrace (only part of them)
It thrown out three exceptions as below : all points out that the problems is caused by the line of "setContentView(layout)" at in layout.xml.
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.ais.cherry/com.ais.cherry.activity.FirstActivity}: android.view.InflateException: Binary XML file line #32: Error inflating class android.support.design.widget.NavigationView

Actually it is not the matter of the primarycolortext, upgrading or downgrading the dependencies.This problem will likely occur when the version of your appcompat library and design support library doesn't match.
Example of matching condition
compile 'com.android.support:appcompat-v7:23.1.1' // appcompat library
compile 'com.android.support:design:23.1.1' //design support library
I had similar error.
When i use
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#673AB7</item>
<item name="colorPrimaryDark">#512DA8</item>
<item name="colorAccent">#00BCD4</item>
<item name="android:textColorPrimary">#212121</item>
<item name="android:textColorSecondary">#727272</item>
</style>
works for me when i remove the android:textColorPrimary and android:textColorSecondary theme items.
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#673AB7</item>
<item name="colorPrimaryDark">#512DA8</item>
<item name="colorAccent">#00BCD4</item>
</style>
Try working with a very simple App theme to start off with.
EDIT:
This tutorial will help.
My understanding is that using "android:textColorPrimary" requires minimum api level 21. Using the same tag without "android:" uses the design support library. Any support library widget will try to find the "textColorPrimary" item instead of "android:textColorPrimary" and if it fails to find the same it throws the above mentioned error.
I also had same error. In my case some of the resources were in drawable-v21 only. Copy those resources to drawable folder also. This solved the issue for me.
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x0
This is the main problem.
If you have already migrated to androidx, you should change your layout xml
from
<android.support.design.widget.NavigationView ... />
to
<com.google.android.material.navigation.NavigationView ... />
I had the same error, I resolved it by adding app:itemTextColor="#color/a_color" to my navigation view :
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="left"
app:headerLayout="#layout/layout_drawer_header"
app:menu="#menu/drawer_menu"
app:itemTextColor="#color/primary"/>
You can still use android:textColorPrimary and android:textColorSecondary in your theme with this method.
Well
So I was trying to fix this error. And none worked for me. I was not able to figure out solution.
Scenario:
I was just going to made a Navigation Drawer Project inside Android Studio 2.1.2
And when I try to change the default Android icon in nav_header_main.xml I was getting some weird errors. I figured out that I was droping my PNG logo into the ...\app\src\main\res\drawable-21. When I try to put my PNG logo in ...\app\src\main\res\drawable bam! All weird errors go away.
Following are some of stack trace when I was putting PNG into drawable-21 folder:

I solved it downgrading in gradle from
compile 'com.android.support:design:23.1.0'
to
compile 'com.android.support:design:23.0.1'
It seems like I always get problems when I update any component of Android Studio. Getting tired of it.
None of the above fixes worked for me.
What worked for me was changing
<item name="android:textColorSecondary">#FFFFFF</item>
to
<item name="android:textColorSecondary">#color/colorWhite</item>
You obviously need to add colorWhite to your colors.xml
Following below steps will surely remove this error.
Find the widget causing the error.
Go the layout file where that widget is declared.
Check for all the resources (drawables etc.) used in that file.
Then make sure that resource is there in all versions of drawables (drawable-v21,drawable etc.)
Cheers!!
As Parag Naik correctly mentions (and Lạng Hoàng expands on), the problem arises when setting textColorPrimary to something other than a color state list. So you could set textColorPrimary as a state list. There is an issue in the android bug tracker about colorPrimary being a state list with only one color: https://code.google.com/p/android/issues/detail?id=172353
So for your theme in styles.xml:
<style name="Base.Theme.Hopster" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primary_dark</item>
<item name="colorAccent">#color/accent</item>
<item name="android:textColorPrimary">#color/primary_color_statelist</item>
</style>
And the actual primary_color_statelist.xml file:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- This is used when the Navigation Item is checked -->
<item android:color="#color/primary_text_selected" android:state_checked="true" />
<!-- This is the default text color -->
<item android:color="#color/primary_text" />
</selector>
In my case, I had the same error when I run the app in kitkat API 19 version device. I figured out the problem; I had some drawable resources which was in the drawable-v21 directory (Which is used for versions from API 21 Lollipop). I just put the same resources in the "Drawable" folder to work with the version below API 21. It works. You can put it on the corresponding directory
For me, I encountered this error many times,
Error inflating class android.support.design.widget.NavigationView #28 and #29
The solution that works for me is that you must match your support design library and your support appcompat library.
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
For me they must match. :) It works for me!
Just for who still get to this issue. I got to the same problem but all the solutions here is not work for me.
Just take alook on NavigationView class with cue from logcat, i found the issue come form this line of code:
itemTextColor = this.createDefaultColorStateList(16842806);
So, it seem related to itemTextColor as Aenur56 mentioned. So i tried with Aenur56's solution but it doesn't work.
Take a look on the line of code above, i notice that there is ColorStateList. So i create one then set for itemTextColor then it work.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#00FF00" android:state_checked="true" />
<item android:color="#000000" />
</selector>
Hope it help!
None of the solutions above helped me. I found this on some other webpage and it worked for me - "In project.properties of design library set target to 21 or highest available, then clean design lib, appcomapt and your project and enjoy"
Hope it will help!
Make sure your drawables for the menu are in the correct folder, mine where put in drawablev21 hence this caused a nullpointer to the resource.
Fixed it buy moving my icons to drawables folder
Generic way of solving issues like Error inflating class X:
check cause stack trace and there should be Resources$NotFoundException like this:
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f0b0066
at android.content.res.ResourcesImpl.getValue(ResourcesImpl.java:190)
at android.content.res.Resources.loadXmlResourceParser(Resources.java:2094)
at android.content.res.Resources.getLayout(Resources.java:1111)
at android.view.LayoutInflater.inflate(LayoutInflater.java:424)
Resource ID is actually exact integer from generated R.java file.
Find 0x7f0b0066 which will point to the xml file which could not be inflated(found).
In most cases that's because directory layout doesn't have this resource, but some layout-XXX has.
And solution is to put resource into all required directories. Or just at least into layout.
In my case i had
<android.support.design.widget.NavigationView...
and in app config:
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.appcompat:appcompat:1.1.0'
So I changed the XML to:
com.google.android.material.navigation.NavigationView...
I had the same problem after upgrading the support library and none of the answers worked for me. Finally I solved downloading latest version of build tools and upgrading in build.gradle to buildToolsVersion "23.0.1"
One thing to double-check is that you have applied your theme correctly in your AndroidManifest.xml file. In my case, I had omitted the android:theme attribute. E.g:
<application ... android:theme="#style/Your.Theme.Here" ... >
BETTER I UPGRADED com.android.support:appcompat-v7:23.1.0
as #Ton said downgrade compile 'com.android.support:design:23.1.0'
BUT Why not to upgrade com.android.support:appcompat-v7:23.1.1
Final upgraded worked for me enjoy
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
So why to use older library. I think is now better to use both design and compact upgraded.
I was also having this same issue, after looking nearly 3 hours I find out that the problem was in my drawable_menu.xml file, it was wrongly written :D
This error can be caused due to reasons as mentioned below.
This problem will likely occur when the version of your appcompat library and design support library doesn't match.
Example of matching condition
compile 'com.android.support:appcompat-v7:24.2.0' // appcompat library
compile 'com.android.support:design:24.2.0' //design support library
If your theme file in styles have only these two,
<item name="colorPrimary">#4A0958</item>
<item name="colorPrimaryDark">#4A0958</item>
then add ColorAccent too. It should look somewhat like this.
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#4A0958</item>
<item name="colorPrimaryDark">#4A0958</item>
<item name="colorAccent">#4A0958</item>
</style>
It's weird but clean project and rebuild project worked for me.
I found solution...
if you used app:srcCompat change to android:src
this solution worked for me :)
I was facing this error in Xamarin. This was due to some files that were present in drawable-v21 folder. So I copied those files (probably icon files) to the drawable folder and the error was gone.
I have been attempting to run this application from this repository
https://github.com/tekinarslan/AndroidMaterialDesignToolbar

It shows the same message even after I replace ActionBarActivity with AppCompatActivity in the SampleActivity.java file..Please help
Replacing android:windowNoTitle with just windowNoTitle fixes the issue.
Had similar problem and
https://blog.xamarin.com/android-tips-hello-material-design-v7-appcompat/
fixed using suggestion given in this link.
<!--If you are using revision 22.1 please use just windowNoTitle. Without android:-->
<item name="windowNoTitle">true</item>
If your intention is to not use actionbar at all and use only toolbar, you can use Theme.AppCompat.NoActionBar as parent. (This I have tried on your git code and it works).
I followed a tutorial of new component NavigationView in Support Design Library and can't get through this error message :

Actually it is not the matter of the primarycolortext, upgrading or downgrading the dependencies.This problem will likely occur when the version of your appcompat library and design support library doesn't match.
Example of matching condition
compile 'com.android.support:appcompat-v7:23.1.1' // appcompat library
compile 'com.android.support:design:23.1.1' //design support library
I had similar error.
When i use
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#673AB7</item>
<item name="colorPrimaryDark">#512DA8</item>
<item name="colorAccent">#00BCD4</item>
<item name="android:textColorPrimary">#212121</item>
<item name="android:textColorSecondary">#727272</item>
</style>
works for me when i remove the android:textColorPrimary and android:textColorSecondary theme items.
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#673AB7</item>
<item name="colorPrimaryDark">#512DA8</item>
<item name="colorAccent">#00BCD4</item>
</style>
Try working with a very simple App theme to start off with.
EDIT:
This tutorial will help.
My understanding is that using "android:textColorPrimary" requires minimum api level 21. Using the same tag without "android:" uses the design support library. Any support library widget will try to find the "textColorPrimary" item instead of "android:textColorPrimary" and if it fails to find the same it throws the above mentioned error.
I also had same error. In my case some of the resources were in drawable-v21 only. Copy those resources to drawable folder also. This solved the issue for me.
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x0
This is the main problem.
If you have already migrated to androidx, you should change your layout xml
from
<android.support.design.widget.NavigationView ... />
to
<com.google.android.material.navigation.NavigationView ... />
I had the same error, I resolved it by adding app:itemTextColor="#color/a_color" to my navigation view :
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="left"
app:headerLayout="#layout/layout_drawer_header"
app:menu="#menu/drawer_menu"
app:itemTextColor="#color/primary"/>
You can still use android:textColorPrimary and android:textColorSecondary in your theme with this method.
Well
So I was trying to fix this error. And none worked for me. I was not able to figure out solution.
Scenario:
I was just going to made a Navigation Drawer Project inside Android Studio 2.1.2
And when I try to change the default Android icon in nav_header_main.xml I was getting some weird errors. I figured out that I was droping my PNG logo into the ...\app\src\main\res\drawable-21. When I try to put my PNG logo in ...\app\src\main\res\drawable bam! All weird errors go away.
Following are some of stack trace when I was putting PNG into drawable-21 folder:

I solved it downgrading in gradle from

to
compile 'com.android.support:design:23.0.1'
It seems like I always get problems when I update any component of Android Studio. Getting tired of it.
None of the above fixes worked for me.
What worked for me was changing
<item name="android:textColorSecondary">#FFFFFF</item>
to
<item name="android:textColorSecondary">#color/colorWhite</item>
You obviously need to add colorWhite to your colors.xml
Following below steps will surely remove this error.
Find the widget causing the error.
Go the layout file where that widget is declared.
Check for all the resources (drawables etc.) used in that file.
Then make sure that resource is there in all versions of drawables (drawable-v21,drawable etc.)
Cheers!!
As Parag Naik correctly mentions (and Lạng Hoàng expands on), the problem arises when setting textColorPrimary to something other than a color state list. So you could set textColorPrimary as a state list. There is an issue in the android bug tracker about colorPrimary being a state list with only one color: https://code.google.com/p/android/issues/detail?id=172353
So for your theme in styles.xml:
<style name="Base.Theme.Hopster" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/primary</item>
<item name="colorPrimaryDark">#color/primary_dark</item>
<item name="colorAccent">#color/accent</item>
<item name="android:textColorPrimary">#color/primary_color_statelist</item>
</style>
And the actual primary_color_statelist.xml file:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- This is used when the Navigation Item is checked -->
<item android:color="#color/primary_text_selected" android:state_checked="true" />
<!-- This is the default text color -->
<item android:color="#color/primary_text" />
</selector>
In my case, I had the same error when I run the app in kitkat API 19 version device. I figured out the problem; I had some drawable resources which was in the drawable-v21 directory (Which is used for versions from API 21 Lollipop). I just put the same resources in the "Drawable" folder to work with the version below API 21. It works. You can put it on the corresponding directory
For me, I encountered this error many times,
Error inflating class android.support.design.widget.NavigationView #28 and #29
The solution that works for me is that you must match your support design library and your support appcompat library.
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
For me they must match. :) It works for me!
Just for who still get to this issue. I got to the same problem but all the solutions here is not work for me.
Just take alook on NavigationView class with cue from logcat, i found the issue come form this line of code:
itemTextColor = this.createDefaultColorStateList(16842806);
So, it seem related to itemTextColor as Aenur56 mentioned. So i tried with Aenur56's solution but it doesn't work.
Take a look on the line of code above, i notice that there is ColorStateList. So i create one then set for itemTextColor then it work.
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#00FF00" android:state_checked="true" />
<item android:color="#000000" />
</selector>
Hope it help!
None of the solutions above helped me. I found this on some other webpage and it worked for me - "In project.properties of design library set target to 21 or highest available, then clean design lib, appcomapt and your project and enjoy"
Hope it will help!
Make sure your drawables for the menu are in the correct folder, mine where put in drawablev21 hence this caused a nullpointer to the resource.
Fixed it buy moving my icons to drawables folder
Generic way of solving issues like Error inflating class X:
check cause stack trace and there should be Resources$NotFoundException like this:
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f0b0066
at android.content.res.ResourcesImpl.getValue(ResourcesImpl.java:190)
at android.content.res.Resources.loadXmlResourceParser(Resources.java:2094)
at android.content.res.Resources.getLayout(Resources.java:1111)
at android.view.LayoutInflater.inflate(LayoutInflater.java:424)
Resource ID is actually exact integer from generated R.java file.
Find 0x7f0b0066 which will point to the xml file which could not be inflated(found).
In most cases that's because directory layout doesn't have this resource, but some layout-XXX has.
And solution is to put resource into all required directories. Or just at least into layout.
In my case i had
<android.support.design.widget.NavigationView...
and in app config:
implementation 'com.google.android.material:material:1.1.0'
implementation 'androidx.appcompat:appcompat:1.1.0'
So I changed the XML to:
com.google.android.material.navigation.NavigationView...
I had the same problem after upgrading the support library and none of the answers worked for me. Finally I solved downloading latest version of build tools and upgrading in build.gradle to buildToolsVersion "23.0.1"
One thing to double-check is that you have applied your theme correctly in your AndroidManifest.xml file. In my case, I had omitted the android:theme attribute. E.g:
<application ... android:theme="#style/Your.Theme.Here" ... >
BETTER I UPGRADED com.android.support:appcompat-v7:23.1.0
as #Ton said downgrade compile 'com.android.support:design:23.1.0'
BUT Why not to upgrade com.android.support:appcompat-v7:23.1.1
Final upgraded worked for me enjoy
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
So why to use older library. I think is now better to use both design and compact upgraded.
I was also having this same issue, after looking nearly 3 hours I find out that the problem was in my drawable_menu.xml file, it was wrongly written :D
This error can be caused due to reasons as mentioned below.
This problem will likely occur when the version of your appcompat library and design support library doesn't match.
Example of matching condition
compile 'com.android.support:appcompat-v7:24.2.0' // appcompat library
compile 'com.android.support:design:24.2.0' //design support library
If your theme file in styles have only these two,
<item name="colorPrimary">#4A0958</item>
<item name="colorPrimaryDark">#4A0958</item>
then add ColorAccent too. It should look somewhat like this.
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#4A0958</item>
<item name="colorPrimaryDark">#4A0958</item>
<item name="colorAccent">#4A0958</item>
</style>
It's weird but clean project and rebuild project worked for me.
I found solution...
if you used app:srcCompat change to android:src
this solution worked for me :)
I was facing this error in Xamarin. This was due to some files that were present in drawable-v21 folder. So I copied those files (probably icon files) to the drawable folder and the error was gone.
I updated my support library from r20 to r21, now when I run my app I get this error in super.onCreate of my main activity :

what is the problem ?
thanks
It happened same to me when I update SDK. If you have version 21 of library "Android Support Library" this bug occurs. I don't know what is the reason but last release make this bug.
You can solve it by downloading previous version of "Android Support Library" (r20) from here: https://dl-ssl.google.com/android/repository/support_r20.zip, and using it in your project.
You are welcome!
I have compared support_v7_appcompat (version 20) with support_v7_appcompat (version 21). In res/values/attrs.xml (version 21), windowActionBar attributes are not in <declare-styleable name="Theme">
if you use intellij => you have to add in /project strutures/modules/ => YOURSDK\extras\android\support\v7\appcompat and add after in your project
like that you have always the last support
I have a class that were extending FragmentActivity and importing android library v4. Now that I want to implement Navigation Drawer in my activity, I'd like to extend ActionBarActivity. And since ActionBarActivity also implements FragmentActivity, I've been told that I could still use fragments in my class with ActionBarActivity.
So I start working with ActionBarActivity, first by importing the v7 library. I copied the file from
C:\Program Files\Android Developer Tools\sdk\extras\android\support\v7
to the libs folder in my app folder on workspace.
Now my Eclipse detects no errors with my class extending ActionBarActivity. However when I run it, it crashes.
Here's some information found at my LogCat (I wonder if it coulp help at any point):

#Raghunandan here's my styles.xml:

the AppTheme is not used in AndroidManifest.xml so just ignore them. I used to use #android:style/Theme.Holo.Light in my custom themes but since I already extending ActionBarActivity in my main class, LogCat indicates I need to use AppCompat Theme.
java.lang.NoClassDefFoundError:
android.support.v7.appcompat.R$styleable
AppCompat is a library project with resources. You need to reference AppCompat in your Android project.
You could also check this a similar one i answered before. Found it now
No resource found that matches the given name '#style/Theme.AppCompat.Light'
You can follow the steps # Adding libraries with resources in the below link
https://developer.android.com/tools/support-library/setup.html
Donwload the support library from sdk manager
Import library project to workspace. Can be found #
sdk>/extras/android/support/v7/appcompat/
After importing
Right click on your Android Project. Goto Properties. Choose Android. Click Add and choose AppCompact. Click OK. You should see a green tick upon success.
After Referencing
You are done.
In Eclipse: File->Import->Existing Android Code into Workspace-> Next. Go to Browse and locate the project "C:\Program Files\Android Developer Tools\sdk\extras\android\support\v7" (in your case) and import it.
Then right click on your project -> Properties. Go to Android section on top left. In the bottom window called "Library" click Add and choose the support project you've just imported.
Make sure you import the ActionBar from import android.support.v7.app.ActionBarActivity and not from the import android.app.ActionBar.
Add suppor library jar using the Java Build Path
I had the same problem and tried whole bunch of things (themes, importing external appcompat jars etc).
The only one helped to me:
1) manually copy android-support-v4.jar and android-support-v7-appcompat.jar to the lib folder of the project;
2) right click on the project -> Properties -> Libraries -> Add JARs (not external jars) - > select jars from the lib folder (which we copied on step 1) -> Order and Export tap -> Uncheck old support libraries and check new, which we just added. -> OK.
