I am trying to use Theme.AppCompat, but when I do the Action Bar simply disappear. There is no errors or whatsoever.
The thing is I'm using this exact setting on two more projects and they work just fine, not sure what changed.
I also tried changing support library version, parent theme, cleaning the project, rebuilding and invalidating cache. Wasn't sure if any of that would help but I did anyway.
I am using Android Studio 0.8.14
Correct me if I'm wrong but that's how I use Material Theme widgets and color palette on older API's, right?

My answer should be as a comment but this is the only way I can reply.
Are you extending ActionBarActivity in your activity?
Have you tried the show() method in your activity?

I'm new to android studio and I have a new version installed (version 1.5.1).
For some reason I keep getting an error message (every time I use an app theme) saying that there were rendering problems: styles missing.
I looked online for solutions, but most of them are outdated or just do not work.
Thanks for any help.
Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.easycodingplus.myapplication">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Build gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.easycodingplus.myapplication"
minSdkVersion 8
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
}
just change your style.xml file like this
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
and then, go to
File > Project Structure > app >
and set (both should be same with latest version )
source compatibility : 1.7
Target compatibility : 1.7
you have to include the dependencies for design which is like this, this will be added under the dependencies block of the app module of the build.gradle
compile 'com.android.support:design:23.1.1'
it should be something like this ..
you need this support library as CoordinatorLayout, AppBarLayout and FloatingActionButton part of it
make a style in the style file
<style name="AppTheme" parent="Base.Theme.AppCompat.Light">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
and reference that in your AndroidManifest file
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="#style/AppTheme">// like this
Please ensure you have the lateset AppCompat library listed as a dependency in your build.gradle file:
com.android.support:appcompat-v7:23.1.0
Can you post which style the error is referring to? You may need to add a style to your res > values > styles folder. Something in your code is probably referencing a style that does not exists in that folder.
try this way:
keep your internet connection
go to "file" in android studio toolbar click on "invalidate caches/Restart" and choose "invalidate and restart"
3 options
1.Select low-level API version
2.Add Base on styles.xml
3.Install previous SDK (if you want)
I also faced the same problem so what I did...go to sdk manager -->tick android 5.1.1 api level 22 and installed it....
then go to Preview window and select other version
I faced the same problem and these steps helped me solve it:
1. File > Other settings > Default Settings > Appearances & Behaviour > File encoding.
2. Change project encoding to windows-1252. Then:
3. File > Invalidate Chaches/Restart.
OR WORST CASE
Change the theme to Material light or something else, one of them should work.
I hope this helps.
I want to develop an Android app with AndroidStudio and the new material design and it looks great on Android 5.0 but when I test the app on my 4.4.2 phone, the ActionBar of the app is missing.
Here is my Manifest:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/MyTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
the styles.xml
<resources>
<!-- Base application theme. -->
<style name="MyTheme" parent="Theme.AppCompat.Light">
</style>
and the build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.0.0"
defaultConfig {
applicationId "com.example.app"
minSdkVersion 14
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:+'
}
Do you know where the error is?
Thank you!

To use the appcompat-v7 action bar backport, you need to have your activities inherit from ActionBarActivity.
Quoting Chris Banes' blog post:
If you are not currently using AppCompat, or you are starting from scratch, then here's how to set it up:
All of your Activities must extend from ActionBarActivity. It extends from FragmentActivity from the v4 support library, so you can continue to use fragments.
All of your themes (that want an action bar/Toolbar) must inherit from Theme.AppCompat. There are variants available including Light and NoActionBar.
When inflating anything to be displayed on the action bar (such as a SpinnerAdapter for list navigation in the action bar), make sure you use the action bar’s themed context retrieved via getSupportActionBar().getThemedContext().
You must use the static methods in MenuItemCompat for any action-related calls on a MenuItem.
UPDATE: Note that Google is migrating to AppCompatActivity. ActionBarActivity works — it is just a do-nothing subclass of AppCompatActivity — but you are better served by directly extending AppCompatActivity if you are going to use the appcompat-v7 action bar backport.
I am currently trying to create an Android app using the Android L SDK version.
However, when trying to build my project using Gradle, I run into the following error:
"Error: Found item Style/AppTheme more than one time"
Which points to my res/values-v21/styles.xml
I know that in res/values/styles.xml there is a style "AppTheme" already defined, but as far as I know I was following the Android developers guide on using Android L. Perhaps someone can help me:
Here is my:

I apologize for the bad formatting, I hope everything is readable.
If anyone knows what I am doing wrong, please let me know. I just want to make an app with that sweet material design.

This bug is because of gradle 0.12.2
So I changed gradle version from 0.12.+ to 0.12.1 and It works well.
The problem is not with the way the application is built (i.e. merging styles from external libraries). The problem is that the Android Studio XML editor is not aware of the resources in the external libraries.
This problem is already being answered by many please have a look at it
IDE "Cannot Resolve #style/Theme.Appcompat" when using v7 compatibility support theme
This is bug because of low gradle you could download gradle from this reference
and replace it with old gradle.
Second solution is update your android studio to newer version.
third Solution is Invalidate / Cache restart.
Hope it help.
I'm starting out with Android development and trying to play around with a test app on Android L.
I want to be able to load the material design theme on the Android L emulator, and standard holo theme on my Android 4.4 emulator. I just really can't get it running.
When I try and run the app I'm getting this error:
Error:Error retrieving parent for item: No resource found that matches the given name 'android:Theme.Material'.
My gradle file is like this:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:0.12.+'
}
}
apply plugin: 'android'

}

targetSdkVersion 'L'
compileSdkVersion 'android-L'
}
old {

targetSdkVersion 20
//TODO comment second line if build is not compiles for "L"
compileSdkVersion 20
}
}
}
dependencies {

I have two styles.xml files:
One in values with:

and another in values-v21 with:
<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.Material">
<!-- Customize your theme here. -->
</style>
What am I doing wrong?
and another in values-v21 with:
The L preview is API 20, not v21
