我们如何在android中获取特定包名的hashkey？

Question

我想通过“SHA1”获取我的Android包名称的哈希键。有人可以帮助我吗？

Answer 1

尝试这种方法......

public static void showHashKey(Context context) {
        try {
            PackageInfo info = context.getPackageManager().getPackageInfo(
                    "com.example.tryitonjewelry", PackageManager.GET_SIGNATURES); //Your package name here
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.i("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                }
        } catch (NameNotFoundException e) {
        } catch (NoSuchAlgorithmException e) {
        }
    }

Answer 2

尝试以下方法，

// Add code to print out the key hash
    try {
        PackageInfo info = getPackageManager().getPackageInfo(
                "com.facebook.samples.hellofacebook", 
                PackageManager.GET_SIGNATURES);
        for (Signature signature : info.signatures) {
            MessageDigest md = MessageDigest.getInstance("SHA");
            md.update(signature.toByteArray());
            Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
    } catch (NameNotFoundException e) {

    } catch (NoSuchAlgorithmException e) {

    }

只需将包名更改为您需要的包。
