Failure: Unable to Deploy and run package on device

I am using Qt 5.12.3. Trying to build a simple Bluetooth communication app for Android.
The build is completed successfully. but I am facing error when Qt tries to deploy the app on the device.I Zygote : ForkAndSpecializeCommon: fork is finished, pid=0 W Zygote : mz_is_rooted false W main : type=1400 audit(0.0:1514415): avc: denied { create } for name="cgroup.procs" scontext=u:r:zygote:s0 tcontext=u:object_r:cgroup:s0 tclass=file permissive=0 I Zygote : ForkAndSpecializeCommon: Beginning of SetGids I Zygote : ForkAndSpecializeCommon: End of SetGids I zygote : Late-enabling -Xcheck:jni W zygote : Using default instruction set features for ARM CPU variant (cortex-a9) using conservative defaults W System : ClassLoader referenced unknown path: I FlymeFontsHelper: UserId == 0 I QtCore : Start W linker : "/data/app/org.qtproject.example.BTHC05-hwskKYzDPYkGkbiwNaGieA==/lib/arm/libQt5AndroidExtras.so" has unsupported flags DT_FLAGS_1=0x80 W linker : "/data/app/org.qtproject.example.BTHC05-hwskKYzDPYkGkbiwNaGieA==/lib/arm/libQt5Bluetooth.so" has unsupported flags DT_FLAGS_1=0x80 W linker : "/data/app/org.qtproject.example.BTHC05-hwskKYzDPYkGkbiwNaGieA==/lib/arm/libQt5Gui.so" has unsupported flags DT_FLAGS_1=0x80 W linker : "/data/app/org.qtproject.example.BTHC05-hwskKYzDPYkGkbiwNaGieA==/lib/arm/libQt5Widgets.so" has unsupported flags DT_FLAGS_1=0x80 W linker : "/data/data/org.qtproject.example.BTHC05/qt-reserved-files/plugins/platforms/android/libqtforandroid.so" has unsupported flags DT_FLAGS_1=0x80 I Qt : qt started I zygote : Do partial code cache collection, code=29KB, data=29KB I zygote : After code cache collection, code=29KB, data=29KB I zygote : Increasing code cache capacity to 128KB I zygote : Do partial code cache collection, code=52KB, data=56KB I zygote : After code cache collection, code=52KB, data=56KB I zygote : Increasing code cache capacity to 256KB E linker : normalize_path - invalid input: "C", the input path should be absolute W linker : Warning: unable to normalize "C" E linker : normalize_path - invalid input: "C", the input path should be absolute W linker : Warning: unable to normalize "C" I Adreno : QUALCOMM build : 85a6576, Ie95bd5cb08 I Adreno : Build Date : 07/17/18 I Adreno : OpenGL ES Shader Compiler Version: EV031.23.02.01 I Adreno : Local Branch : mybranch34750041 I Adreno : Remote Branch : quic/gfx-adreno.lnx.1.0.r32-rel I Adreno : Remote Branch : NONE I Adreno : Reconstruct Branch : NOTHING I Adreno : PFP: 0x016ee164, ME: 0x00000000 I zygote : android::hardware::configstore::V1_0::ISurfaceFlingerConfigs::hasWideColorDisplay retrieved: 0 I OpenGLRenderer: Initialized EGL, version 1.4 W ResourceType: Failure getting entry for 0x010400df (t=3 e=223) (error -75) E SpannableStringBuilder: SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length W libBTHC05.so: qt.bluetooth.android: ACCESS_COARSE|FINE_LOCATION permission available I BluetoothAdapter: startDiscovery F libc : Fatal signal 11 (SIGSEGV), code 1, fault addr 0x730085 in tid 8953 (qtMainLoopThrea), pid 8930 (.example.BTHC05) "org.qtproject.example.BTHC05" died.

From the log I can see you added Bluetooth permissions to your manifest, did you also add
android:name="android.permission.ACCESS_COARSE_LOCATION"/>?
-
@J.Hilk yes it has included "android.permission.ACCESS_COARSE_LOCATION". But I haven't made changes in the android manifest, it is default version being generated by Qt.

@ahsan737 alight
Well the app actually deploys correctly and starts and your bluetooth instance is scanning for devices.
So a good point in time to enable remote debugging on your device and do just that.
Start a debug build (with the debugger attached of course), let it crash and inspect the backtrace

@J.Hilk thank you, that sounds so technical. Actually, I am a beginner so I do not have a deep understanding of it. And yesterday it was all working fine.
