Page does not render completely and keeps on flickering through appium but renders correctly when done manually

I have a test case scenario to add medicine to a cart as below:
send medicine name in textbox
from the search results select the medicine by clicking ADD button
verify add medicine
Issue: When I click on the add button in step 2, the medicine gets added, but the page starts to flicker i.e. page keeps on rendering or refreshing (I don't know what to call in exactly), and so I am not able to perform the next steps.
One more concern is that the same scenario works perfectly when executed manually. The issue occurs only for execution done via appium. If I stop the appium server at the point where issue occurs, the flickering stops.
So seems to me like appium is messing something up.
My Android app is React Native app.
At the point of failure I can see below failure in adb logs:

You need to increase the RAM and internal storage size that you are assigning to the emulator in order for that exception to go away. You are trying to do some action in the android code that's eating up the emulator's RAM and internal memory.

Android app crashes instantly after adding RealmReactPackage

I followed the instructions from the realm page and did these steps:
npm install realm
react-native link realm --> For iOS everything works out without any further steps at this point.
Opened android studio and updated changes in settings.gradle, app/build.gradle and imported the RealmReactPackage in MainApplication.java
If I build and start the app, everything is working out fine. Then I add new RealmReactPackage() to the list to the other ReactPackages.
If I start the app now, the app crashes immediately. The logcat doesn't say any reason for the crash, but I add the output anyways below.
Things I tried already:
Clear caches
Restart packager
Deinstall app from emulator
Clear node-modules and run npm install again and repeat the steps from above
My setup:
"react": "16.3.1",
"react-native": "0.55.4",
"react-native-navigation": "v2.0.1937"
Node version 9.5.0
Android Studio version: 3.1.3
What I didn't do so far:
There is one instruction at the realm site under Examples:
Note that on Android, you need the NDK installed and must have set the ANDROID_NDK environment variable.
export ANDROID_NDK=/usr/local/Cellar/android-ndk/r10e
My Question is, is this relevant for my config or just for the examples?

I've succeeded in running my fingerprint HAL on Android 8.1 executing on HiKey
96 board after modified files as below.
Firstly, it's necessary that adding HIDL configures to declare a device as a vendor or you would get VTS failed.
About HIDL configures
device/linaro/hikey/manifest.xml
+<hal format="hidl">
<name>android.hardware.biometrics.fingerprint</name>
<transport>hwbinder</transport>
<version>2.1</version>
<interface>
<name>IBiometricsFingerprint</name>
<instance>default</instance>
</interface>
</hal>
Secondly, finger service will be started after you define it in the file below.
device/linaro/hikey/device-common.mk
+#init finger service and copy
android.hardware.biometrics.fingerprint#2.1-service.rc to
system/vendor/etc/init
+PRODUCT_PACKAGES += \
+android.hardware.biometrics.fingerprint#2.1-service
+# copy permission file of finger service
+PRODUCT_COPY_FILES += \
+frameworks/native/data/etc/android.hardware.fingerprint.xml:system/etc
/permissions/android.hardware.fingerprint.xml
Finally, check finger service has been started and running in Android system by using terminal commands such as "adb shell" and "ps | grep finger".
Any suggestion is welcome.

I found out that I need to add the code to the manifest.xml
(Ref. https://source.android.com/devices/architecture/vintf/objects )
<hal format="hidl">
<name>android.hardware.biometrics.fingerprint</name>

Cannot execute HelloJni app with Valgrind

I am developing on a Nexus 4 device with Android 5.1.
Installation info:
I have used the "build_valgrind.sh" script to cross-compile valgrind (for api android-21) and to copy it to /data/local/Inst.
I have also copied "start_valgrind.sh" to /data/local/ folder, giving all permissions ("chmod 777) to the script.
Then I set properties to the HelloJni app.
adb shell "su -c 'setprop wrap.com.example.hellojni \"logwrapper /data/local/start_valgrind.sh \"'"
The actual problem comes when I try to execute the app:
adb shell "su -c 'am start -a android.intent.action.MAIN -n com.example.hellojni/.HelloJni'"
The logcat output I get is posted at the end.
When I execute the HelloJni app without setting logwrapper properties, it executes as expected. I am not sure what I am doing wrong, but it looks as if I have problems with "CheckJNI is OFF". Has someone been able to execute any application with this approach? Any help will be appreciated.

MVVMCross 3.5.1 and xamarin android does not work

I have a question: is there somebody that use MVVMCross 3.5.1 with Api level android 21 and xamarin studio 5.9.3? I have a problem: I reference mvvmcross in an android app. I have a splashscreen and a firstview. When I tried to start with emulator I don't have any problem with level 15 emulator but when I tried it with the last version (Api 21) the app after splashscreen is closed without any error (not open the firstview).
Is there a solution?
UPDATE
I tried with logcat. In the following I attached the log:

UPDATE 2
The bind does not work. Inside the view..
UPDATE 3
I put the code in this repo:
https://onedrive.live.com/redir?resid=1E563B1D1AD8A1C!15847&authkey=!AII01sfuzToQiUQ&ithint=file%2czip
I used this configuration for the test:
1. Nexus 5,
2. Android 5.0-API Level 21,
3. CPU/ABI, I have chosen Google APIs Intel Atom(x86_64),
4. Use Host GPU.
UPDATE 4
new link for code: http://1drv.ms/1MZWf45
Thanks
Alessandro

I found the problem. The problem was the emulator. I tried to change the configuration and now run without problem.
Thanks
Al.
