Ionic v1 build error converting bytecode to dex

I got a problem building ionic v1 after sync another kotlin project.
when I use cordova run android the error i get is this:
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.
UNEXPECTED TOP-LEVEL EXCEPTION:

What went wrong: Execution failed for task ':transformClassesWithDexForDebug'.

Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
In my file build.gradle file i have my compile options to VERSION_1_6
I also have changed my jdk version to 6 and 7 I already have 8. And I tried changing the version to VERSION_1_7, still the same.
I changed it to VERSION_1_8 and asks for jackOptions to be enabled but i get this.

Proguard flag dontobfuscate causes Translation has been interrupted exception

I've came across following exception. When I omit -dontobfuscate flag in Proguard config everything is fine.
Any ideas how to enable this flag and complete build?

I meet the same problem, I fix the problem after some test.
Find your 'myTask' buildType configuration in build.gradle file.
Modify proguardFiles getDefaultProguardFile('proguard-android-optimize.txt') to proguardFiles getDefaultProguardFile('proguard-android.txt')

Can you check if in Android Studio you have all the correct plug-in install.
Look also if you don't have some weird in you Ressources folder.
Yesterday, I had the same issue, I look in the res folder and is see a lot of... Unknown file on this directory. After I remove it, it work.
Perform a full clean and a rebuild project can also help sometimes

Kotlin and Android databinding (BuildTools 2.0.0)

In my Android project I am using Kotlin and Android Data binding. It works very well but now I wanted to update android gradle plugin to version 2.0.0-beta5. When building the project I get the following error:
Exception is here

did anyone already encounter this problem and is there a way to fix it?

This was indeed happening to me while using the beta 5 version:
classpath 'com.android.tools.build:gradle:2.0.0-beta5'
You can upgrade now to the latest version (beta 6 as of today) and it should fix the problem for you:
classpath 'com.android.tools.build:gradle:2.0.0-beta6'

It is happens because android data binding written on Kotlin (it was announced on Android Dev Summit 2015 Framework Fireside Chat) preview version. In new version of Kotlin JetBrains clean language for realease. Svetlana Isakova told about this in one of her presentation. So this method was removed from lang what is cause of exception.
I had remove binding from project for solving this problem

Android data binding, cannot generate view binders

I'm using android-data-binding library, I set the dependencies in build.gradle as:
classpath 'com.android.tools.build:gradle:1.3.0'
classpath "com.android.databinding:dataBinder:1.0-rc4"
I got these errors, have checked several leads but got no idea what causes this, since it's too abstract, don't know whether it's a missing variable in my xml file, or a missing function in my viewmodel. Any tip? thanks
Error:Execution failed for task ':app:compileDebugJavaWithJavac'.

You could try deleting these folders in the Project and see if it works, it did for me: .gradle, .idea, gradle

Now databinding:dataBinder dependency is no more needed. Just enable data binding inside android tag in your app level build.gradle.
android {
...
dataBinding {
enabled = true
}
}

According to this answer you must remove dataBinder:1.+ and use gradle:1.5.0, also remove apply plugin: 'com.android.databinding'remove and just add below lines into app.gradle file
android {
dataBinding {
enabled = true
}
...
}
I hope this will help you.
