Here is the Gradel.build

android {
    compileSdkVersion 23
    buildToolsVersion '24.0.0 rc1'
    defaultConfig {
        applicationId "com.kim.printer"
        minSdkVersion 21
        targetSdkVersion 23
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    productFlavors {
    }
}

dependencies {
    compile 'com.google.android.gms:play-services-gcm:8.4.0'
    compile 'com.google.code.gson:gson:2.4'
    compile "com.android.support:support-v4:23.1.0"
    compile "com.android.support:support-v13:23.1.0"
    compile "com.android.support:cardview-v7:23.1.0"
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile files('libs/StarIOPort3.1.jar')
    compile files('libs/StarIO_Extension.jar')
}

Thanks for any help I have been working on this for 6 hours and I can get it to compile.

Check if the path to JDK is set correctly. You can do this in Android Studio by clicking on _File_ -> _Project Structure_ -> _SDK Location_ -> _JDK Location_. And change in you gradle build these lines: `sourceCompatibility JavaVersion.VERSION_1_8` `targetCompatibility JavaVersion.VERSION_1_8` — Benjamin Lücking, Mar 10 '16 at 07:56
I change the JDK location back to 7 and the sourceCompatibility/ targetCompatibility back to 1_7 after I got the 235 errors. leaving the JDK on 7 and changing to 1_8 i get this error. Error:Execution failed for task ':app:compileDebugJavaWithJavac'. > invalid source release: 1.8 — Kim HJ, Mar 11 '16 at 04:22

The problem is in the buildToolsVersion '24.0.0 rc1' after changing it to '23.0.2' I no longer get errors.

Also see http://stackoverflow.com/a/36620618/369317 Basically newer build tools (24.x) seem to work with jdk 8. – Denys Kniazhev-Support Ukraine Apr 14 '16 at 11:17

This problem occurs when you update to Android Studio to 2.0.

To solve this problem:

Open build.gradle file
Change buildToolsVersion "24.0.0 rc1" to buildToolsVersion "23.0.2"

Happy coding.

Why **23.0.2**, and not **24.0.3**? – IgorGanapolsky Nov 28 '16 at 20:44

This problem is related with your SDK, not with your JDK. You can check your version information from

Help > About > Show Details

You will get something like

Xamarin.Android Version: 6.0.2.1 (Starter Edition) Android SDK: X:\Android\android-sdk

Supported Android versions:

4.0.3 (API level 15)

4.4 (API level 19)

6.0 (API level 23)

SDK Tools Version: 24.4.1

SDK Platform Tools Version: 23.0.1

SDK Build Tools Version: 24 rc2

Java SDK: X:\Program Files (x86)\Java\jdk1.7.0_71

java version "1.7.0_71"

Java(TM) SE Runtime Environment (build 1.7.0_71-b14)

Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode, sharing)

If you are using preview tools for building ,then you will get similar errors all over.

What to do now?

Tools -> SDK manager

Select all items in preview channels including Android SDK build tools with rev 24rc2 or 24rc4(latest)
Click on Delete 'n' packages

How to turn off preview channel

In SDK manager, select

Tools > options
Uncheck Enable preview tools

And what

Back to your code Clean all and rebuild

well said. I was looking for this for two days – Riyas PK Jul 29 '16 at 08:54 — Riyas PK, Jul 29 '16 at 08:54

Using Android SDK Manager, I removed my last update of Android SDK Build-Tools v.25 remaining with the previous one: v.23.0.3....

...now it's working as it should do!!!
