What Android networking protocols/encryption actively in use?

Given you have doubts to the contextual info on the encryption schemes the WiFiAnalyzer (Open Source) app is showing, you might want to use other utilities to confirm or disprove your suspicions. Try installing the popular Wireshark utility on a computer connecting to the same local network as your mobile devices, it's free, with a very reputable, long history, and available for Linux, Mac, and Windows.

Install and configure Wireshark, and do a scan on your home LAN, making sure one or more of your mobile devices is awake, and preferably actively doing something that's online. Following these directions you should be able to at least get some corresponding data on the encryption scheme in use:

You might also want to install the GlassWire app, it's a network monitor and firewall utility that you can also use to correspond with the information from the WiFiAnalyzer app and Wireshark scan results.

A last suggestion is to try to crack your own home WiFi network and see if it is or isn't as openly vulnerable as you think it is:

Using images/hardware profiles: Emulator

When it comes to testing on emulators, how common is for developers to test on different AVDs (actual emulators) build with "different images" and "hardware profiles"? I am referring to `emulator avd create` as in this link http://www.androiddocs.com/tools/devices/managing-avds-cmdline.html#AVDCmdLine (The link is a bit old but it shows the command). Right now all my testing has been focused on a single image/API. What is your testing strategy? Is emulators even in your testing plan?

I am also using this as a reference: http://www.androiddocs.com/tools/devices/index.html

This is probably a better link as it is associated to official documentation:
https://developer.android.com/studio/run/emulator#android_virtual_devices

One of the challenges on using different platform during testing is that, from what I understand, the platform also depends on the build-tools version. I have had issues of platform/build-tools compatibility before but the root cause issue is not 100% clear to me... yet.

Any comments or if you don't mind sharing your experiences. Thank you,

Apps No Device Compatibility

I am seeking to publish an app. I tested the app using my own phone, on which it ran just fine. But in the Google Play Console its not listing any "SUPPORTED DEVICES" in the "Device catalog".

What did I do wrong? How can I fix this?

I have the compile and target SDK version set to 28
The minimum SDK version is set to 19

I was trying to use a bundle instead of an APK

any help would be appreciated

Huawei watch in a loop

I have issues with my Huawei smart watch, i just doesn't boot up ( its in a loop) neither i am able to do factory reset as it doesn't stay on the reset screen even for 2 seconds. Huawei support has been pathetic and unable to understand the issue. However, i noticed if i keep the charger plugged in for some time, i does turn on but the moment you try doing something it just reboots ( in a loop).
Not under warranty!!

Could be the battery is finished?

No idea how much it would be for Huawei to replace it, or if it's possible.

AMR file voice recording playing but no sound (Samsung Galaxy Note 2)

its an old phone not all things will work when you want it to. not sure if the recorded is recoverable or not.
Thing is, I recorded another recording just after that and it worked just fine. Its mind boggling coz its playing but it just doesnt have any sounds in it. I would accept it if the background noise is there or if the audio came back on the middle of the recording but its total silence.

Best gaming tablet?

Hey, have a look at Microsoft Surface Pro 3 Tablet:

* 64 GB Internal Storage
* 4 GB Ram
* 10.8 Inch Display

Price: 528$

Check it out. I hope you will like it.

its a good tablet, but i don't think it would that great for games. i mean it is a windows device so you can't play android games. you can play basic windows or pc games, but the processor and graphics would not be that great for most pc games......just saying.
