Mali Graphics Debugger: Not getting trace data in GUI

I spent hours trying to get MGD working without voiding my warranty by rooting my device.  I finally managed to get it going.  Here's what you have to do on the UNITY side (you also have to follow the manual about getting MGDDeamon on your device):

Copy libMGD.so into your Unity Project's Assets/Plugins/Android folder.

Create your own Activity that derives from UnityPlayerActivity and throw the hook in there.  Then compile that .java into a .class, then put that .class into a .jar.  Finally, place a modified AndroidManifest.xml in your Assets/Plugins/Android folder which will launch your modified activity as the main activity.

Here is the code for the Activity:  [Java] Mali Debugger Unity Activity - Pastebin.com

Here's how I compile the .java and .jar it up:

set CurrentDir=%~dp0%

set JdkBin="C:\Program Files\Java\jdk1.8.0_66\bin"

set AndroidJar="B:\Junctions\Android\sdk\platforms\android-23\android.jar"

set UnityJar="B:\Junctions\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\mono\Development\Classes\classes.jar"

set TargetJavaDir=%CurrentDir%

set TargetJava="SOME_SOURCE\com\CodingJar\MaliDebugActivity.java"

set TargetJar="SOME_SOURCE\Assets\Plugins\Android\CodingJar-Development.jar"

pushd %JdkBin%

javac -bootclasspath %AndroidJar% -cp %UnityJar% -source 1.6 -target 1.6 %TargetJava%

jar cvf %TargetJar% -C %TargetJavaDir% "com/CodingJar/MaliDebugActivity.class"

popd

The AndroidManifest.xml which you can base yours off of is found in Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Apk

I have only tested this with Google Cardboard and it appears to work.  If any Mali engineers are watching, PLEASE supply us with a custom function we can call in your libMGD.so so that it can mark the end of a frame.  This way we can use it for VR rendering as well without waiting for you to figure out what to hook instead of eglSwapBuffers.

Cheers.

Thanks for the steps! We get a lot of people asking about MGD + Unity, so I'll raise this with the team and see if we can add some Unity specific steps to our documentation.

As for the VR support, I believe the team are aware of the problem, and we plan to support it.

Thanks,

Chris

Hi,

MGD v3.4.1 has been released Mali Graphics Debugger - Mali Developer Center  and supports VR with frame detection. Let us know if you have any issues.

Cheers,
