Determine Android device performance programmatically

Question

I want to run different lines of code for android devices with different performance. For example something like this:

if (isHighPerformanceDevice()) {
    // run code for devices with high performance
} else if (isMediumPerformanceDevice()) {
    // run code for devices with medium performance
} else {
    // run code for devices with low performance
}

Or at least:

if (isHighPerformanceDevice()) {
    // run code for devices with high performance
} else {
    // run code for devices with low performance
}

I wonder if there is something in Android SDK I can use or those methods should be implemented manually? I would appreciate any guidance on this, thank you.

Devices with Android 10 and higher.

I'd prefer you to get the drive performance using its RAM.

To get RAM values simply do:

ActivityManager actManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    ActivityManager.MemoryInfo memInfo = new ActivityManager.MemoryInfo();
    assert actManager != null;
    actManager.getMemoryInfo(memInfo);
    long totalMemory = memInfo.totalMem;
    long availMemory = memInfo.availMem;
    long usedMemory = totalMemory - availMemory;
    float precentlong = (((float) (availMemory / totalMemory)) * 100);

Here you will get Total as well as Free and Used RAM size. The value of these will be in "long", so format it to human-readable (i.e in MB/GB). Use the following method to do so:

 private String floatForm(double d) {
    return String.format(java.util.Locale.US, "%.2f", d);
}

private String bytesToHuman(long size) {
    long Kb = 1024;
    long Mb = Kb * 1024;
    long Gb = Mb * 1024;
    long Tb = Gb * 1024;
    long Pb = Tb * 1024;
    long Eb = Pb * 1024;

    if (size < Kb) return floatForm(size) + " byte";
    if (size >= Kb && size < Mb) return floatForm((double) size / Kb) + " KB";
    if (size >= Mb && size < Gb) return floatForm((double) size / Mb) + " MB";
    if (size >= Gb && size < Tb) return floatForm((double) size / Gb) + " GB";
    if (size >= Tb && size < Pb) return floatForm((double) size / Tb) + " TB";
    if (size >= Pb && size < Eb) return floatForm((double) size / Pb) + " Pb";
    if (size >= Eb) return floatForm((double) size / Eb) + " Eb";

    return "0";
}

Now you can customise this code to your needs. I can't say that 1 Pb RAM is hight performance or low performance in your case. It depends on what your app does. That is the thing u need to do
