getActiveRuntimeCursor Null cursor when querying system content resolver

[jdshaoheyi]

Description

On Android , i got error msg "getActiveRuntimeCursor Null cursor when querying system content resolver", when i start an [android native activity] in [android app] that build with unity 2019. i debug this problem long time, and i really did not know why...

General Troubleshooting

• [1 ] create an empty unity application, add one test button and click listener, call one java test method to launch [android native activity]
• [2] [android native activity] is a native activity than load dynamic library [alxr-client-pico]

Environement

unity 2019, Android Studio Electric Eel | 2022.1.1

Hardware

pico neo 3 pui 5.3.4

Installation

i used alvr old version , last commit sha-1 is d70c019:

Hello, can you please give more context, I don't understand if you're asking for help with running an unity app on pico or if it's an issue with ALXR.

If it is about ALXR it looks like you're using a very old build, please use the latest nightly builds (alxr-client-pico.apk not -v4 that is for PUI versions below 5.2).

very thanks for response, i will test latest alvr later. the core problem is when i start a android native activity(native lib is alxr-client-pico) inner a unity app i got the error message.

hi, i tested alvr server 18.2.3, alxr-client-pico.apk is build with commit SHA-1 32c206b, everything is ok when i change nothing. but i got very same error when i modify alvr\openxr-client\alxr-engine-sys\android\app\build.gradle with these changes:
1.BUILD_LOADER: OFF-->ON
2.USE_PICO_MOBILE_LOADER: ON--->OFF
PicoMobileOXR {
dimension 'headset'
ndk {
abiFilters 'arm64-v8a'
}
externalNativeBuild.cmake.arguments += [
"-DANDROID_TOOLCHAIN=clang", "-DANDROID_STL=c++_static",
"-DBUILD_LOADER=ON", "-DUSE_PICO_MOBILE_LOADER=OFF"
]
}
3. another question is what difference between prebuilt libopenxr_loader.so and self build libopenxr_loader.so ?
