Unsupported abi:

Error message

Unsupported abi: 

What it means

ShareTinkerInternals.getCurrentInstructionSet maps Build.CPU_ABI to an instruction set string (arm, arm64, x86, x86_64, mips, mips64). An ABI outside this list throws IllegalStateException("Unsupported abi: " + Build.CPU_ABI). The device reports an ABI the loader cannot translate into an odex ISA.

Solutions

1. Log Build.CPU_ABI (and CPU_ABI2/SUPPORTED_ABIS) on affected devices to identify the unknown value.
2. Update Tinker to a version whose ABI map covers your devices (or patch the switch in a fork).
3. Constrain patch distribution to supported ABI device sets.
4. Catch IllegalStateException where instruction set feeds odex path computation and fall back to an ABI-derived mapping.

Example fix

// before
default:
    throw new IllegalStateException("Unsupported abi: " + Build.CPU_ABI);
// after
default:
    String[] abis = Build.SUPPORTED_ABIS;
    String mapped = mapKnownAbi(abis != null && abis.length > 0 ? abis[0] : null);
    if (mapped != null) currentInstructionSet = mapped;
    else throw new IllegalStateException("Unsupported abi: " + Build.CPU_ABI);

String[] known = {"armeabi", "armeabi-v7a", "arm64-v8a", "x86", "x86_64", "mips", "mips64"};
String abi = Build.CPU_ABI;
if (abi == null || !Arrays.asList(known).contains(abi)) {
    // unsupported ABI: skip odex/instruction-set dependent paths
}

static boolean isSupportedAbi(String abi) {
    if (abi == null) return false;
    switch (abi) {
        case "armeabi":
        case "armeabi-v7a":
        case "arm64-v8a":
        case "x86":
        case "x86_64":
        case "mips":
        case "mips64":
            return true;
        default:
            return false;
    }
}

try {
    String isa = ShareTinkerInternals.getCurrentInstructionSet();
} catch (IllegalStateException e) {
    // 'Unsupported abi': device ABI unknown to this Tinker version
}

When it happens

Trigger: Calling getCurrentInstructionSet (directly or via optimizedPathFor on Android O+) on a device whose Build.CPU_ABI is not one of the six known values.

Common situations: Newer ABIs on preview/exotic hardware (e.g. riscv64), emulators reporting unusual ABI strings, or 32-bit processes on devices where CPU_ABI reflects the 64-bit primary ABI.
