I have the same issue when just ask dji sdk about something.
As an example DJISDKManager.getInstance().product
If you need more details, please let me know I will create demo app with this crash.

And this crash is not related for video stream decoding.
It happens from the start of app.

sdk version: 4.10
mobile: Sumsung S7 edge
android studio: 3.4

[Ray-DJI]

Hi, @hxl-dy @samoilovich . DJI SDK with 4.10 have updated the secure strategies. Please add following lines in your project build.gradle
packagingOptions {

doNotStrip "*/*/libdjivideo.so"
doNotStrip "*/*/libSDKRelativeJNI.so"
doNotStrip "*/*/libFlyForbid.so"
doNotStrip "*/*/libduml_vision_bokeh.so"
doNotStrip "*/*/libyuv2.so"
doNotStrip "*/*/libGroudStation.so"
doNotStrip "*/*/libFRCorkscrew.so"
doNotStrip "*/*/libUpgradeVerify.so"
doNotStrip "*/*/libFR.so"

// Add the new so
doNotStrip "*/*/libDJIFlySafeCore.so"
doNotStrip "*/*/libdjifs_jni.so"
doNotStrip "*/*/libsfjni.so"
exclude 'META-INF/rxjava.properties'

}

Thanks for the feedback, we will update the tutorial with the SDK 4.10 as soon as possible.

Same problem with me, adding these lines does not solve it.
Looks like it happens on call to DJISDKManager.getInstance().getSDKVersion()...

@PadreCocoRocha thanks for the feedback, could you please provide a public github repo? with that our developer could clone it and reproduce your issue.

[chano1025]

clean project -> rebuild project

[Padreco-lbr]

clean project -> rebuild project

That solved for me, thank you

Out of curiosity: Where is that 4.10 SDK available? All the sample apps are still using 4.9.

[Ray-DJI]

@accuware Our 4.10 SDK already have published for almost one month, and the VideoStreamDecodingSample have updated with the latest 4.10 SDK.

@Ray-DJI I see. This is surprising, since I cloned the sample a week ago. I see you have updated 5 days ago...Since you also have updated the YUV part I will check it out. Thanks

@Ray-DJI
I faced one more issue. Your previous solution works! But when I tried to test release version with turned on proguard I get the crash:
Process: com.measure.groundcontrol, PID: 22027 java.lang.NoClassDefFoundError: Failed resolution of: Landroid/arch/lifecycle/LifecycleObserver; at dji.sdk.sdkmanager.DJISDKManager.getInstance

Could you help with that?

[samoilovich]

@Ray-DJI
I have added keep annotation to proguard file for android architecture component from this link
https://gist.github.com/brownsoo/9b11a823360c9cf184263df3e669375c
And it helped but I think that this moment should be fixed.
Please let me know if you need any info.

[Ray-DJI]

Hi, @samoilovich You are right, the architecture component should keep from obfuscating, because our SDK AAR Package depends on the architecture component aar.
Each time when we release a new version, we will give the proguard file to tell the developer which class or method should be kept. You can refer to the DJI sample APP for more information about proguard file.

[samoilovich]

Any dji sample app?
hmmm. https://docker.pkg.github.com/DJI-Mobile-SDK-Tutorials/Android-VideoStreamDecodingSample
I tried to find here the proguard file. But could :(
Could you send a link?

[Ray-DJI]
