Android: byte to dex conversion error

Question

So, I get the following error when starting a project after updating build.gradle (Project) from

dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha2' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } 

to

 dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } 

I just changed gradle from 2.0.0-alpha2 to 2.0.0-alpha3 and then tried to create a project.

Error Log:

Any help would be appreciated.

Answer 1

Good. I don’t know how it worked.

First, I cleaned up the project, and then, starting the project, everything worked out.

Turn on, first Clean , and then Run .

Change Clean works first, and then Make Project .

Answer 2

In my case, I first Clean project, then click the Make Project button as below image , then it will start working. Rebuild does not work for me.

And I also update the Google repository .

Answer 3

In my case, I put

apply plugin: 'com.google.gms.google-services'

at the bottom of the build.gradle file and set multiDexEnabled true to defaultConfig . Then just run and it works.

Answer 4

If you use any plugins. Then, in your Gradle file (usually app/build.gradle ), make sure you add the apply plugin line at the bottom of the file to enable the Gradle plugin.

eg.

Answer 5

I met the same problem and I cleaned the project, some other problems caused cannot be cleared, so I manually delete the dir 'build', so it can clear Ok and then run fine for me.

Answer 6

In my case, I found this problem caused by an incorrect build.gradle configuration. I had two different versions of com.google.firebase. After the versions were the same, the problem was resolved.

Answer 7

I met the same problem.
First delete the build folder from the project location (you can access it through the Android studio or using Explorer), then build project.

Answer 8

In my case, the problem was due to capitalization in some packages.

Answer 9

Just restart your AS and then Rebuild your application!

Answer 10

After I upgraded to Android Studio 2.1, the next time I rebooted, I was asked to upgrade to JDK 1.8. After I upgraded to JDK 1.8, this happened when my AS project had problems compiling. I followed all the suggestions on this page, but to no avail. Finally, I decided to check out the version of the JDK that my project was using, and, to my surprise, this somehow pointed to JDK 1.8!

Moral of the story: if compileSdkVersion <= 23, double check that your project uses JDK1.7 as follows:

• Right mouse on top-level module
• Project Structure => JDK Location

Answer 11

In my case, this was due to the fact that my library was not configured as "android". For example. apply plugin:'java' instead of apply plugin:'com.android.library'

Answer 12

Verify that you build.gradle (Module: your application).

All com.google.android.gms libraries should use the same version specification (mixing versions may cause runtime crashes).

For example: If you have com.google.firebase: firebase-ads: 9.6.1 and com.google.android.gms: play-services-basement: 10.0.1

You need to change the firebase version to: 10.0.1

Answer 13

Add this block inside android in build.gradle

dexOptions { preDexLibraries = false }

Answer 14

Before:

 compile 'com.google.android.gms:play-services-location:10.0.1' compile 'com.google.android.gms:play-services-auth:10.0.1' compile 'com.google.firebase:firebase-database:10.2.0' compile 'com.google.firebase:firebase-core:10.2.0' compile 'com.google.firebase:firebase-messaging:10.2.0' 

After:

 compile 'com.google.android.gms:play-services-location:10.2.0' compile 'com.google.android.gms:play-services-auth:10.2.0' compile 'com.google.firebase:firebase-database:10.2.0' compile 'com.google.firebase:firebase-core:10.2.0' compile 'com.google.firebase:firebase-messaging:10.2.0' 

Finally, he was allowed.

Answer 15

This problem is mainly found in gradle or in incorrectly translated libraries, including from libraries when both define the same class. Expand and verify imported external libraries ...

You cannot export two identical classes in one place or code, therefore dexer does not know which one should be used ...

Answer 16

For some reason, @ChintanSoni's answer did not work. I tried to delete the build folder manually, but could not delete some files, since they were used by some process. Cleaning up and restoring the project did not help, so I opened the task manager , selected the JAVA(TM) Platform SE binary and clicked on "Final Task".

Then I tried to run the project again, and it started to compile a fine.

Answer 17

 dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile fileTree(include: 'Parse-*.jar', dir: 'libs') compile 'com.android.support:appcompat-v7:23.2.0' compile 'com.android.support:cardview-v7:23.2.0' compile 'com.android.support:design:24.0.0-alpha1' compile "com.google.firebase:firebase-invites:9.2.0" compile "com.google.firebase:firebase-ads:9.2.0" compile 'com.google.firebase:firebase-database:9.2.0' compile 'com.google.firebase:firebase-core:9.2.0' } 

I add the line com.google.firebase:firebase-core:9.2.0 and select the same version (9.2.0) for all firebase libraries, and the problem has been resolved.

Answer 18

If you have several projects, make sure you do not add the dependency several times, I had to exclude another project dependency as follows:

 compile(project(':OtherProject-SDK')) { compile.exclude module: 'play-services-gcm' compile.exclude module: 'play-services-location' compile.exclude module: 'support-v4' compile.exclude module: 'okhttp' } 

Answer 19

Just clear and try again for me.

Answer 20

My project used an external library with heterogeneous versions of Java compatibility in my build.gradle files (1.7 and 1.8). I fixed it using the same version for lib and for the application project. In my case, for both:

 compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } 

Answer 21

Try installing through :app:installDebug . If it works, then it is associated with Android Studio caches. I deleted the .gradle/ folder inside my project and it works.

Answer 22

It was very easy for me. Just add:

// noinspection GradleDependency, GradleCompatible implementation of 'com.google.android.gms: play-services-auth: 11.0.4'

... and the magic happens.

Answer 23

I had the same problem and it was caused by the wrong version of Google Analytics and firebase. I used 'com.google.gms:google-services:3.1.0' and then added these dependencies:

 compile 'com.google.android.gms:play-services-gcm:10.2.6' compile 'com.google.firebase:firebase-crash:10.0.1' 

So change the firebase version to 10.2.6 to fix this problem.

 compile 'com.google.android.gms:play-services-gcm:10.2.6' compile 'com.google.firebase:firebase-crash:10.2.6' 

Answer 24

If you enter the code from the same library from two different sources that will cause an error.

Answer 25

This question has many answers, but if you haven't solved your mistake yet, this might work:

Sometimes we import different versions from google / API products, so try organizing a gradle file to solve: Mixing versions warning

Answer 26

I had the same problem and realized that the two separate jar files that I had in the app / libs folder had the same packages as the auxiliary dependencies that caused the conflict.

Answer 27

I noticed that this can happen (sometimes) when editing java files while creating Android Studio.

I solved this by manually deleting the build folder and starting the agi.

Answer 28

In case this helps someone, in my case I used a special package in release mode, and not in debug mode.

I just changed the package from "release" to "debug" and it worked.

Answer 29

The thing that worked for me.

1. Go to the Android folder of your application.
2. To run. / gradlew clean

Answer 30

First, build -> clean project -> restore it again.

If it does not work, then in your build.gradle set multiDexEnabled true

eg:

 defaultConfig { applicationId "com.example.myapplication" minSdkVersion 21 targetSdkVersion 27 multiDexEnabled true versionCode 1 versionName "1.0" testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner" }
