Android: Dex Cannot Parse Version 52 Byte Code

Android: Dex cannot parse version 52 byte code

just use java 1.8 with Android Studio 3.0+ and set following works for me:
it seems need the latest build tools

classpath 'com.android.tools.build:gradle:3.0.0'

and

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"

    defaultConfig {
        ...        
        //jackOptions { // DEPRECATED
            //enabled true
        //}
    }
    dexOptions {
        incremental true
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

Error:Error converting bytecode to dex: Cause: Dex cannot parse version 52 byte code

Thanks everyone for answer. The problem was that this library (compile 'com.myhexaville:smart-image-picker:1.0.4') gave conflict. When I removed it everything worked finally.

Building Cordovo Android app fails - Dex cannot parse version 52 byte code error message

It reads:

ParseException: bad class file magic (cafebabe) or version (0034.0000)

0x0034 is version 52 byte code, which means the some class had been compiled with JDK 8, which is not being understood by that version of dex. It even explicitly demands the source/target compatibility mode:

Dex: Error converting bytecode to dex:
Cause: Dex cannot parse version 52 byte code.

This is caused by library dependencies that have been compiled using Java 8 or above.

If you are using the 'java' gradle plugin in a library submodule add
targetCompatibility = '1.7'
sourceCompatibility = '1.7'
to that submodule's build.gradle file.

So there are two options:

a) either follow the advice and edit the compileOptions (this not only applies to the java plugin):

android {
    compileOptions {
        // sourceCompatibility JavaVersion.VERSION_1_6
        // targetCompatibility JavaVersion.VERSION_1_6
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

b) build with JDK 8.

You are actually building with rather old versions:

dependencies {
    classpath "com.android.tools.build:gradle:2.2.3"
}

task wrapper(type: Wrapper) {
    gradleVersion = "2.14.1"
}

while the current versions are:

dependencies {
    classpath "com.android.tools.build:gradle:3.5.0"
}

task wrapper(type: Wrapper) {
    gradleVersion = "5.4.1"
}

When I read version 2.2.3 I'd assume a version of Android Studio just as old. Update to Android Studio 3.5.0 and have an embedded JRE 8 installed with it. That Android Studio might still have an embedded JRE 7 (no matter what the JDK on path claims to be, because the global JDK and the embedded JRE are two different installations). The same goes for Gradle, because it might use the local wrapper at version 2.14.1 instead of the global installation at version 5.6.1. One can tell Gradle to use a specific JDK with org.gradle.java.home, but the IDE might in general be too old. You'd need at least Android Studio 3.0.0 for Java 8 support.

Version 52 byte code corresponds to Java 8, you need to add below to your app/build.gradle to make your project be compatible with Java 8.

android {
    ...
    defaultConfig {
        jackOptions {
            enabled true
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    ...
}

YOu change

compileOptions.with {
            sourceCompatibility = JavaVersion.VERSION_1_7
            targetCompatibility = JavaVersion.VERSION_1_7
        }

to

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
