android pre dex errors in Android Studio

Question

I recently try to open up a project developed sometime ago into Android Studio and try to rebuild it and I get whole load Android Pre Dex errors which I am totally stuck how I get rid of them. Tried a lot of stuff such as changing Android API level, cleaning, change jdk version.. all doesn't work.

Any experts out there can enlighten me what is the likely cause of these errors.?

Step 1: Add multidex enabled in default config

defaultConfig {
    applicationId "Your package name"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 5
    versionName '1.0.5'
    multiDexEnabled true
}

Step 2 : Add this library in your dependencies

    compile 'com.android.support:multidex:1.0.0'

Step 3 : Add this line in your MyApplication extends Application java class

 MultiDex.install(this);

Step 4: Don't forgot to call MyApplication class in your Application tag of manifest file. Like this

 android:name=".MyApplication"

After this 4 steps clean your project and run the application. Surely it will helps you!

Happy Coding!

Thanks alot! Will try and get back! However in step 3 and 4.. i do not seem to have a MyApplication class.. do i have to create? – atonic Jul 28 '16 at 15:30
Yes you have to create new java class that extends Application. – sudharsan chandrasekaran Jul 29 '16 at 04:40
public class MyApplication extends Application{ @Override public void onCreate() { super.onCreate(); MultiDex.install(this); } }} – sudharsan chandrasekaran Jul 29 '16 at 04:42
It seems that they cannot find the MultiDex class in MyApplication. Do I have to add something else? Thanks for your help! – atonic Aug 01 '16 at 02:35
Manage to find out from to make MultiDex class recognized in Android Studio by following this http://stackoverflow.com/questions/27910824/android-multidex-install – atonic Aug 01 '16 at 03:17
But this answer does not works.. still the same set of 22 Android Pre Dex errors... :( – atonic Aug 01 '16 at 07:00
for me multiDexEnabled true was enough no need for other steps – Shady Mohamed Sherif Jun 06 '18 at 23:52

i already solved it it happen because you didnt setting the default java in android studio 2.3.3 or android studio 3.0 beta 6

go to file > project structure > SDK location
change the JDK Location to C:\Program Files\Java\jdk1.8.0_131
