How i want to fix this error?

How is Google.com going to relevant in this case? Are you being sarcastic? Smh

Hi,

could you check the solution recently posted by dm3d here:

Hi AlessandroB,

I have created an app with Unity5.2.0 and Vuforia 5-0-6 and published on Play store with android:targetSdkVersion = 23. working fine with all the devices except Android 6.0 marshmallow. 

marshmallow devices are encounter "Failed to initialise Vuforia" problem.

As per your suggestion, i have down the android:targetSdkVersion from 23 to 22 and build the apk file. 

but am unable to publish new Apk file with targetSDK 22. 

What will be the ultimate solution ? please suggest. here is the error image .

You will need the 32-bit Unity Editor:

I set up the project following the docs and I didn't have any issues with the vuforia unity package. I uploaded imagetargets to the cloud database and my app recognized them. Today I transfered the project from a windows machine running windows 8 64bit to a windows 10 machine 64 bit. Both machines have the same version of Unity (5.1.1 64bit).

NOTE: 

if you are working with the Native SDK with Android Studio, the targetSdkVersion should be specified in the app build.gradle file (located under the "/app" subfolder of your project)

You can avoid having to handle runtime permissions by setting the targetSdkVersion to 22 (or lower) in the Android Manifest, see here:

Any news about this as I am experiencing the same problem with the need of activating manually the permissions on Android 6?

Cheers,

Good

I am having a similiar issue. I made a copy of my project in order to integrate google cardboard without messing up my app, however when I go back to the original I get the "Vuforia failed to Initialize".

I plan to attempt to generate a new key, I'll let you know what ends up working for me.

It sounds like you're seeing an issue similar to the one discussed in this thread:

https://developer.vuforia.com/forum/device-support/android-m-vuforia-initializing-failed

I'm seeing the same.  When the App installs it says it doesn't need any special permissions.  

Any ideas what is going on here?

OK, I' ll try to remain calm here...

My nexus upgraded today to android 6.0 and I had to manually enable the permissions (camera etc.) from the settings of the app. Now vuforia initializes again..

Yesterday I was developing on lollipop and today on marshmallow and had to go to settings->Apps->{yourAPP} and tap on permissions. There make sure to enable all of them... I lost 7 hours trying to figure out what I was doing wrong with my code etc.. and finally was only a permission issue caused by Android 6.0...
