I'm just moving from Eclipse to intimidating Android Studio and can't get rid of what seems like a pretty common mistake.
Error:Execution failed for task ':app:preDexDebug'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-oracle/bin/java'' finished with non-zero exit value 1
I looked through everything and tried various solutions, ranging from simply restarting my Studio, Invalidating and clearing the cache, removing the JAR and trying to add them again, but so far nothing has worked. I am very new to this development environment, so I donβt even know how it works and what the assembly files should look like.
Here is my current build.gradle (Module: app)
apply plugin: 'com.android.application' android { compileSdkVersion 21 buildToolsVersion "21.1.2" defaultConfig { applicationId "com.example.culami" minSdkVersion 21 targetSdkVersion 21 compileOptions { sourceCompatibility JavaVersion.VERSION_1_7 targetCompatibility JavaVersion.VERSION_1_7 } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } } dependencies { compile 'com.android.support:appcompat-v7:21.0.3' compile 'com.android.support:support-v4:21.0.3' compile files('libs/WebSocket.jar') compile files('libs/android-support-v13.jar') compile files('libs/json-org.jar') compile files('libs/socketio.jar') }
The project was imported from Eclipse, and the reason is that I ran into some build problems using json-org.jar and WebSocket.jar. I could not fix it, and the problem is still open . I am not sure how to add these dependencies via gradle, because the github page does not really tell how to do this.
Here's the output from the gradle console.

Any help on fixing this preDexDebug error would be a big help! As a side note, I also cannot see the βlibsβ folder in the project explorer on the left.
