Hi @lillogoal, thanks for your feedback! We will investigate this issue and fix it in the future SDK version.

[lillogoal]

ok you, but I noticed that with the official app dji go. how is it that with the official app works well? the Chamber (osmo) is detected and the connection goes perfectly. How Can i do ? @oliverou

[oliverou]

Hi @lillogoal, which Android SDK version you are using? Android SDK 3.4.1? Could you help to check if you open DJI Go and the Sample App on your mobile device at the same time? Please make sure DJI Go app is stopped running in the background when you run the Sample App.

[lillogoal]

@oliverou here my answer.

DJI SDK Is 3.4.1 YES. THIS IS MY GRADLE: `ndroid { compileSdkVersion 25 buildToolsVersion "24.0.2" defaultConfig { applicationId "com.wesii.wesiiplay" minSdkVersion 19 targetSdkVersion 25 versionCode 1 multiDexEnabled true

    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}`

I also tried to compile with android sdk 22. But nothing changes nothing. NO NO i can't open dji go and my app in same time.

[oliverou]

I guess the issue is due to the DJI Go app run in the Android system background and grab the device connection. Please go to "Settings->Apps->DJI GO->Force Stop" as shown below:

Make sure there is no other DJI related apps running in the background and try the demo again. It should works.

[lillogoal]

Yes. Although I had tried something similar. I noticed that the app (sample FPV DEMO), if I do not close the application forcefully at times when I open does not recognize the camera "Unknown aircraft". How can you fix this bug? (Then it is the same test that you did). But I did not understand how to solve app side. @oliverou THANK YOU

This issue has been resolved, close it now.
