Does not install!

So, I have the Samsung Tablet A 10.1 and I tried installing the app but it does not let me... What do I have to do now?

If it doesn't install, your device isn't supported.

Unfortunately Android doesn't give us a nice way of showing that and the only way to show that is through a pretty weird workaround on our part which nobody feels like doing.

The reason is likely that your device has a 32 bit userspace. Dolphin requires 64 bit CPU and userspace.

Weird my android version is 7.0

Android version is (mostly) unrelated to the architecture it was built for (such as 32-bit or 64-bit).

For many apps, there's no great advantage for 64 bits over 32 bits, it takes more flash storage (as you need a 64-bit copy of all the libraries it uses), the code size is larger so it can use more ram and cache. So even today many vendors don't bother with a 64-bit userspace on the mid to low end devices. Even if the devices' hardware (IE the CPU) can support 64-bit mode fine.

If you want to double check, you can install something like aida64 from the play store, and see if "arm64-v8a" is in the "Supported ABIs" list - which is under "CPU" in aida64. Without that, no 64bit apps will be able to run.

Plus, it seems that the "Samsung Galaxy Tab A 10.1" uses A53 CPU cores at 1.6ghz. Which will run dolphin /incredibly/ slowly even if it did work (dolphin doesn't work well with the narrow instruction decode of the 'small' cores like the a53 - and often runs at less than half the speed of the equivalent "big" core at the same frequency).
