Android studio multidex And Ndk issue

Question

I am using android studio for developing android app. I have one project which is having two modules as library and both the modules having few libraries common(.so file) due to this I am getting multi-dex issue. Below is the gradle message

> Error:Execution failed for task ':ftrScanApiAndroidHelperUsbHost:compileReleaseNdk'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/home/intel/BackUp/Ndk/ndk-build'' finished with non-zero exit value 2

I tried below solution for this issue but this didn't work for me

defaultConfig{
       multiDexEnabled true
    } 

build.gradle file:

> apply plugin: 'com.android.application' // apply plugin: 'android'

local.properties below:

sdk.dir=/home/intel/Takencode/Android/Sdk

ndk.dir=/home/intel/Takencode/Android/Ndk

Is there any other solution for the above error? Any suggestion

Answer 1

Finally after googling a lot I rectify the issues.Things that goes wrong for above issue.

Case 1:In modules I'm having jni and jnilibs few files common(.so files) ...so I deleted the jni folder because it containing the same .so file...removing redundancy and conflict from the project.

Case 2:There may be the case where modules(Library) and main project's theme,icons are different(defined in AndroidManifest.xml file). In order to correct that look for manifest file...make the module and main project theme same..

In my case module having below Theme

android:theme="@style/AppTheme" 

and main project having

 android:theme="@android:style/Theme.Holo.Light.NoActionBar"

so I change module theme same as project theme.

Also add below line to manifest tag

xmlns:tools="http://schemas.android.com/tools"  

Once added above line add below line to application tag

tools:replace="android:icon,android:theme"

Now it working flawless.

You have to add dependency of support library in your gradle

compile 'com.android.support:multidex:1.0.1'

If you already have a custom application you have to change that instead of extending Application you have to extends that class with MultiDexApplication like this

MyApplication extends MultiDexApplication {

}

If you don't have any custom application class only need to add this in manifest inside application tag

<application
   android:name="android.support.multidex.MultiDexApplication">   
</application>

If you don't need the whole play service you can remove the dependency and add only those dependencies you needed like this

compile 'com.google.android.gms:play-services-gcm:8.1.0'
compile 'com.google.android.gms:play-services-maps:8.1.0'
compile 'com.google.android.gms:play-services-location:8.1.0'

then no need to make your application MultiDex

For ndk you can see this SO Thread

You may give it a try!

sourceSets {
    main {
        jni.srcDirs = []
        assets.srcDirs = [] //disable automatic ndk-build call
    }
}
