Audio output and Audio input flag denied by client on implementing pjsua2 voice call on Android 5.1?

I am implementing pjsua2 sample app for voice call on Android devices. It works well on android version 8, 9, 10, 11 without issue. But when I tested on Android 5.1, I can receive call from sip soft phone without any issue. But outgoing call only rings on the other side without any voice.
From the log its mentioned that both AUDIO_OUTPUT_FLAG_FAST as well as AUDIO_INPUT_FLAG_FAST denied by client. can any one suggest me how to rectify this issue.
as per below log : audio details

When running against the production servers I get a "FAILED" status when trying to get IAP product information available like price name etc.
I have their Amazon App Tester app installed and it recognizes the local json I've uploaded.
Does it look like a broken linking maybe or Pro guard invalid config file ? I'm a beginner on Android development , was able to implement Play Store IAP's sucessufully in the past but seems I'm missing something regarding the Amazon Store IAP.

Since API 30 you need to add queries to the manifest file. For Amazon this is needed:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...>
<queries>
<package android:name="com.amazon.venezia"/>
</queries>
It's really weird that they didn't write that in their documentation.

Thanks a lot, Simon ! I've included the queries part like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.mycompany.myapp">
<queries>
<package android:name="com.amazon.venezia"/>
</queries>
<uses-feature
android:name="android.hardware.camera"
android:required="true" />
But I still get the command service not installed error:

I've included the .pem file as they suggested in the project's assets directory but it seems it didn't work:
AppstoreAuthenticationKey.pem
Do you have any clue of what might be the issue ?

Check you have the Amazon App Tester app installed and configured with your IAP json data, along with the correct receiver tags in your merged AndroidManifest. Additionally, make sure you have sandbox mode enabled on your test device(s):
https://stackoverflow.com/a/71393893/18483253
See also my answer over here:
https://stackoverflow.com/a/71588959/18483253

Thanks #Chris for your answer! I had the same problem, regrettably it took me a while to understand some connections behind the testing process, so I'd like to summarise a few things that I found out.
Apart from the actual coding, a common mistake seems to be the missing receiver in the Manifest. If you encounter the issue, doublecheck here:
https://developer.amazon.com/docs/in-app-purchasing/iap-implement-iap.html#responsereceiver
Make sure you have downloaded the PEM-file and put it in the right directory. Doublecheck here:
https://developer.amazon.com/docs/in-app-purchasing/integrate-appstore-sdk.html#configure_key
Now the misunderstanding that I had: When testing in-app purchases with Google Play, the device is actually loading the products from the server. But here's a major difference for Amazon: When testing with the Amazon App Store in Debug mode, the test-device will NOT connect to the server, but the request is handled by another test app, the Amazon App Tester:
https://www.amazon.com/-/de/gp/mas/get/android/ref=mas_buy_client?showAsin=1&asin=B00BN3YZM2
But it is not enough to have the app installed on the test device, you also need to download the sku-definition from the web-interface and push it to the test-device. When you then open the Amazon App Tester app, you can see your sku(s) in the last section. Only if you see them there, your test requests will be handled by the app!
Here's the tutorial video with the specific steps to set up the device:
https://www.youtube.com/watch?v=cmPAY16wGb0&list=PL93Q4ZD_4z4oUkRM0ap23LAN3HBENuXt2&index=9&t=289s
I hope this also helps for your understanding!

ExoPlayerImplInternal: Stop failed. java.lang.IllegalStateException - on API Level 22 and below

Your video uses H.264 Main Profile (avc1.4D) which is not supported by these particular devices. The minimum requirement for Main Profile is 6.0+. You could check if there's another software decoder available (see MediaCodecSelector), although ExoPlayer will pick the best one.

Android Camera API Error 100 only on back camera

I'm trying to capture an image from the back camera using the Android Camera API.
I'm using this code, 4. Tutorial: Using the camera API. It works when it uses the front camera. When I change CAMERA_FACING_FRONT to CAMERA_FACING_BACK, I get the Error 100 on
camera.takePicture(null, null, new PhotoHandler(getApplicationContext()));
I'm using Samsung Galaxy S3. Anyone knows how to solve this? It has been asked a multiple times, but I haven't found a real solution anywhere.
Edit: Full log until Error 100
