1. Calling com.secneo.sdk.helper.install/com.cySdkyc.clx.Helper.install causes a crash:

JNI DETECTED ERROR IN APPLICATION: field operation on NULL object: 0xθ
in call to GetObjectField
from java.lang.String java.lang.Runtime.nativeLoad(java.lang.String, java.lang.ClassLoader, java.lang.Class)

solution：

Please select the options indicated below in Android Studio, and clear the cache before running it again.

 

2.Calling SDKManager.init causes a crash

java.lang.NoClassDefFoundError: Failed resolution of: Ldji/v5/common/callback/CommonCallbacks$CompletionCallback;

Solution：

  • Check dependencies. Below is the correct way:
implementation 'com.dji:dji-sdk-v5-aircraft:{sdkversion}' 
    compileOnly 'com.dji:dji-sdk-v5-aircraft-provided:{sdkversion}'
  • Check calling install function。Below is reference:
override fun attachBaseContext(base: Context?) {
        super.attachBaseContext(base)
        // 在调用 install 前，请勿调用任何 MSDK 相关
        com.secneo.sdk.Helper.install(this)
    }
  • Move SDKManager.getInstance().init to be executed inside activity or main thread.

 

3.Compile with a resource file or R file not found

solution：

Please downgrade the gradle version to Gradle 7.x or configure android.nonTransitiveRClass = false in gradle.properties.

 

4.Could not find com.mapbox.mapboxsdk:mapbox-android-accounts:0.7.0.

solution:

During the compilation of the MSDK V5 example, where it stated 'Could not find com.mapbox.mapboxsdk:mapbox-android-accounts:0.7.0.' How should address this?

    Ahhhhhhh thank you Yating

    The JNI DETECTED ERROR IN APPLICATION: field operation on NULL object: 0x0

    .. was killing me!  It occurred whenever I made any change to the code (even a newline) after installing and running the app the first time.

    Note that you'll have to re-check this if you change your app name in Settings.gradle
