Android Studio 1.5.1 rendering problems

Question

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 I looked online for solutions, but most of them are outdated or just do not work.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'
}

Answer 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

Answer 2

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.

Answer 3

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

Answer 4

try this way:

keep your internet connection

go to "file" in android studio toolbar click on "invalidate caches/Restart" and choose "invalidate and restart"

Answer 5

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

Answer 6

3 options

1.Select low-level API version

2.Add Base on styles.xml

3.Install previous SDK (if you want)

Answer 7

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.
