Can't install APK even after meeting requirements (Xiaomi Redmi 4X 3/32)

[StephenMD]

Since I got this phone (2 days ago) Ive seen videos of Dolphin playing pretty well on Xiaomi so I decided to search the APK and install it.
I did just that but everytime I install it, it gives me the "Application couldn't install" error.
I did some research and the only thing I could find is that this error means that my phone doesn't meet the "technical requirements".
I analyzed the requirements required and my phone's specs and I noticed that I meet the requirements but I still can't install the app.
I tried using the Development APK but they are too buggy and most of the games are loading up in black screen.
Help me please!

If the application does not install, you do not meet the requirements. This is not an error.

First, you didn't tell us which model of Xiaomi you had.

Second, if it doesn't install, it's generally because your Android phone is not running a 64 bit userspace. You might have a 64 bit capable SoC, and you might even have > 3 GB of RAM. But it is extremely common for vendors to ship devices with 32 bit userspace on 64 bit capable hardware.

There is nothing you can do about this.

i mentioned in the title of the thread the model of the phone.
but is there a way to install a 64bit userspace?

Unfortunately, it is not.  Xiaomi, chose to use the 32bit version Android on your device.  Hmm, I see a lot of snapdragon 430-5 devices running 32-bit android OS.  I wonder if it's capable of running 64-bit android at all?

The problem is not the CPU, but the RAM. 64-bit userspace uses more RAM, that's why 64-bit Android generally is on 3GB+ phones. Also it needs a faster internal storage because the 64-bit userspace may be a little slower compared to 32-bit due to it use more instructions.

64 bit is not slower, it is faster.
64 bit may require a bit more memory, but we're talking about less than 100 MB here.
And I can't read the argument about memory interface being 32 bit any more, the L1 cache size is bigger as well, pointer size doesn't matter.
64 bit requires a bit more on the NAND as 32 bit must be supported as well, maybe 400 MB?

BUT 64 bit requires all userspace drivers and validation twice, so it is just more work for the manufactors. They are lazy.

It may be faster for mid-end or high-end phones. I've seen a lot of people that used both 32-bit and 64-bit on weak phones, the benchmarks showed a lower result on 64-bit. The same happens if you install a 64-bit Windows on a weak PC, I already did this on an old Atom laptop with 2GB of RAM, it ran slower than 32-bit.

For what Dolphin does, it's significantly faster, so benchmarks aren't relevant.

Sure, but it's a good reason for OEMs not to bother with 64bit on entry level devices even if they technically could.

Regardless, even if the Xiaomi redmi 4x was running 64bit, it would still run Dolphin really really badly. But again, it isn't so there's nothing that can be done about it and you can save yourself the disappointment.
