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 developing an app with minSdkVersion 11, targetSdkVersion 23 and compile/build tool version 23. On android versions, 5 and 6 my app works fine, but installing the app on versions below 22 modifies some layouts, like buttons and text fields disappear or color changes, help me with this.

Screen Shot of android version 22(Works fine)
Screen Shot of android version below 22(problem occurs)
When you use an element that was introduced in API 21, and you try to show it on a phone with API 11, there surely will be a problem. For the older versions, you have to differentiate between the elements that you are showing - if some element is not meant to be used in API lower than 21, then you have to provide if-else check and if the API is lower than 21, then use some simple element that you are sure was supported even in API 11.
For example, if you want to use TextInputLayout, you surely can, as the library supports API 22+, but for the lower versions you should probably input text by adding classic EditText. You add both of them to your XML, hide them, and then based on user's API you show one or other.
Also, read this document.
https://developer.android.com/training/basics/supporting-devices/platforms.html
Especially this should help you get an idea what and how to do it:
private void setUpActionBar() {
// Make sure we're running on Honeycomb or higher to use ActionBar APIs
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
Good luck :)
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.

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 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?
Recently I upgraded my nexus 5 to Lollipop. and I create an app using AppCompat-21. The styles under values-v21 are as follo
<resources>
<style name="AppTheme" parent="android:Theme.Material.Light">
</style>
</resources>
but when I run the app, it crashes with the information:
Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
here is my build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
applicationId "geone.businspector"
minSdkVersion 11
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-v7:21.0.0'
}
It runs great under the device pre-Lollipop...
I googled a lot and had no good solution. anybody met this before? ps: I'm using Android Studio 0.8.14 and I'm new to Android Studio. thx.
The error clearly states that you're using the wrong theme. The activities you're using are from the android.support package, these activities need a ThemeCompat theme, not the Theme.Material.Light, which is for activities in android.app package. Rewrite your theme like so:
<resources>
<style name="AppTheme" parent="Theme.AppCompat">
</style>
</resources>
And this error will be gone.
Under your values/styles.xml you would be using Theme.AppCompat.Light
Use the SAME parent theme for your values-v21/styles.xml as well. This will get rid of the error as it did for me.
On Lollipop devices the theme works like it actually should so no worries :)
So I had the same issue and I got soooo tired of Googling it and seeing persons say not to use the Material Theme. Not using Material Theme changes the actionbar to gray even when you set a color for it in styles.
Anyway, the fix is that the android templates created by android studio use import android.support.v7.app.ActionBarActivity; instead of import android.app.Activity; and extend ActionBarActivity instead of activity for the main class. Just change the main class to extend an Activity instead of an ActionBarActivity. Of course more changes will have to be made if you are not using a Blank activity.
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.
