64 Bits Android

[Temika]

Afterreading some documentation, e.g. -changes-all#bouncy-castle and observing the code, I found out that application is generating AES secret keys of 384 bits in size. Obviously, Bauncy Castle java security provider handle this situation, but Conscrypt is failing at runtime.

Hey, thanks for being helpful, but turned out that build error i was having was completely unrelated to this topic, in fact it was a general issue with that particular verison of unity that I updated to, combined with my current build settings!

I have made a 64 build for android and uploaded successfully on play store . My app has VR support for Cardboard and daydream.

Now for 64 build VR is not supporting. VR scene is running as normal 3D scene. Same app is running well with 32bit of build.

Plz help

Hi, I notice that retroarch 64 bits offers severals improvements like dolphin and beetle psx at full speed on android shield tv. I make cohabit the 2 retroarch applications 32 bits and 64 bits on my shield tv.is the 32 bits installation is needed if 64 bits offer better support ?is there some cores that work better on 32 bits ?So to resume, is 32 bits worth installed or is the 64 bits edition is the way to go in the future?thanks for your advices.regards

Posted by Serban Constantinescu, Product Manager,Pixel 7 and Pixel 7 Pro are the first Android phones to support only 64-bit apps. This configuration drops OS support for 32-bit code, reducing memory usage, improving performance, and enhancing security. Over time, we expect this device configuration to become commonplace.

Thanks to the efforts and collaboration of the entire Android community, our ecosystem is ready. Transitioning Android devices to 64-bit-only required many changes across the platform, tooling, Play, and, of course, your apps. We started by introducing 64-bit support in 2014, announcing policy changes in 2017 and requiring support for Google Play apps starting 2019.

64-bit apps run faster because they have access to extra registers and instructions that aren't available to 32-bit apps. In addition, newer CPUs deliver up to 25% better performance when running 64-bit code or even drop support for 32-bit code altogether.

64-bit can help improve security. The bigger address space makes defenses like ASLR more effective and the spare bits can be used to protect control flow integrity. These countermeasures may reduce the chance an intruder can take control of your device.

Removing support for 32-bit code saves up to 150MB of RAM, which was used by the OS even when not running 32-bit apps. These memory savings result in fewer out-of-memory conditions meaning less jank and fewer background app kills.

With 64-bit-only devices now reaching users, we encourage developers to start paying extra attention to testing their apps and updates for 64-bit-only devices. To support this, Google Play now provides pre-launch reports that are run on 64-bit-only devices to detect and report compatibility problems.

Note: While 64-bit-only devices will grow in popularity with phones joining Android Auto in this group, 32-bit-only devices will continue to be important for Android Go, Android TV, and Android Wear. Please continue supporting 32-bit ABIs; Google Play will continue serving 32-bit apps to 32-bit-only devices.

Your 32 bit libraries should get installed automatically. Are you sure you don't have additional 64bit libraries inside your APK?When you install an APK, the system will look for native libraries directories (armeabi, armeabi-v7a, arm64-v8a, x86, x86_64, mips64, mips) inside the lib folder of the APK, in the order determined by Build.SUPPORTED_ABIS.If your app happen to have a compatible 64bit directory with missing libs, the missing libs will not be installed from another directory, the libs aren't mixed. That means you have to provide the full set of your libraries for each architecture.So, to solve your issue, you can remove your 64-bit libs from your build, or set abiFilters to package only 32-bit architectures:android

defaultConfig

abiFilters "armeabi", "armeabi-v7a", "x86", "mips"

I will double check this behavior with our engineering team. In the meantime, since my attempt to reproduce the issue you are describing with our demo was not fully successful, would you mind providing more information on this issue?

Thanks for the reply. The behavior that I observed is an issue with our demo app, and it will be fixed in the demo app of the next release. Please let us know if you have any additional info regarding the unexpected behavior that you have mentioned but I was not able to reproduced. If the behavior is reproducible and happening in our SDK, we will identify it and fix it asap.

Thanks for the check.

When would you estimate the next version of the SDK to be released alongside the fixed demo? Would you be able to share the pointer to the exact part of the fixed code on this thread?

Glad to hear that the stop sharing issue has been resolved and thanks for sharing the findings. I will need to consult the engineers on this interesting behavior and get back to you with updates. I will also try to get the new code regarding this part as well.

I have upgraded to the latest SDK that was published today, but it still behaves the same:

If I kill my app locally, then screen sharing continues + if the app is kicked out of the meeting by the host, the overlay buttons remain on the screen.

Thanks for the reply. You can implement the onShareActiveUser callback( -sdk-android/us/zoom/sdk/InMeetingShareController.InMeetingShareListener.html#onShareActiveUser-long-) to handle the case that the screen is not stopping when the host forces the sharer to stop sharing. You can refer to the following code snippet:

Thanks for the reply. We have looked into this issue and it is a little bit complicated to fix in the demo. Hence we will introduce a fix for this issue and add an SDK method for this situation. The fix will be included in the next release, which is coming soon. Once that version is available, I will show you how to fix it easily.

After double-clicking on the downloaded zip file, the platform-tools directory is created in the same location. In the platform-tools directory, you can see the adb (Android Debug Bridge), which is used to side-load the applications. The below diagram shows the resulting expanded zip file which created the platform-tools directory.

The screen-shot below shows that we have navigated to the platform-tools directory that we created in the above steps. We run ./adb devices from that location and see the serial number of the attached Karoo 2. Several fields have been blocked out to obscure personal information.

Note that for the Zwift Companion app specifically, the Dashboard/Zwifters/Messages pages tend to work best, whereas the map page is a bit more funky because of the small screen size. It works, but your metrics sorta overlay atop 2/3rds the map.

Oh, and if you need to get out out of the app, simply hit the lower-left button (back), which gets you back to the Karoo screen. Remember just like on your phone, this app is still running in the background though. But, this does allow you to switch back and forth between apps.

Indeed, there are pros and cons to this. The big pro is flexibility to do geeky things (like my screen recording), or even practical things (like running other training apps). Or further, an easier development path for 3rd party app developers.

Wahoo Element, Elemnt Bolt and Elemnt Roam devices are also Android devices. Details here link to joshua0.dreamwidth.org and here link to joshua0.dreamwidth.org Also some info can be found in link to groups.google.com

However, the ancient and customized Android version used, the screens and processor make the process of sideloading apps at best not optimal.

Do they have the equivalent of 3rd party ConnectIQ data fields yet? I imagine that would be straightforward for them, simply displaying the output of a small app inside a small area of the screen. I routinely use 3 data fields on my Edge 830.

I run Xert on my K1. Waiting for my K2. I expect that Xert may be one of the first of the mark with a native app as it already works well.

OsmAndMaps is also a great addition , particularly good for off road navigation.

Not sure how you would brick the device by sideloading. You could if you start rooting it to install google services so caution.

With sideloading the worst is usually freezing and turning off and on again deals. If you manage to do something worse then resetting the device does the business and once you are signed in everything back although you will have to repair sensor.

I think they may be a little on the small side to develop their own app store so sideloading will always be a useful option. I hope that some of the most popular apps, Komoot, Xert may be developed directly for the Karoo so they could just come as native.

Got TrainerRoad loaded on my Karoo 2. How do I execute a TR workout outdoors on the K2? When I select perform workout outdoors, it looks like all I can do is read the workout and when I select to do it indoors, I cannot pair my bike power meter to the app.

With the K1 I used nova launcher and it put a little side menubar on the screen. I could click to enter the ride or click to enter another app. I used OSMAnd frequently since back then the mapping was pretty bad on the K1.

Sorry I do not have any idea. I just have the exact same issue on my karoo 2. I get like 15 or so satellites, karoo gps app shows the correct position in seconds.

I have updated osm, nothing helps.
