I want to generate a sha-1 so I can use the google maps v2 in my android app, im using oracles java jdk1.77.025 on ubuntu-mint. I get the following error:
marko@marko-K39a2 /usr/local/java/jdk1.7.0_25/bin $ keytool -list -v -alias androiddebugkey -keystore /home/marko/.android/debug.keystore -storepass android -keypass android list: unrecognized option '-keypass' list: Try 'list -help' for more information this is very strange since I have build a key before and I never had problems. Thanks
if you put this somewehere in your app it will print it for you:
try { PackageInfo info = getPackageManager().getPackageInfo("my.package.name", PackageManager.GET_SIGNATURES); for (Signature signature : info.signatures) { MessageDigest md; md = MessageDigest.getInstance("SHA"); md.update(signature.toByteArray()); String something = new String(Base64.encode(md.digest(), 0)); //String something = new String(Base64.encodeBytes(md.digest())); Log.e("hash key", something); } } catch (NameNotFoundException e1) { Log.e("name not found", e1.toString()); } catch (NoSuchAlgorithmException e) { Log.e("no such an algorithm", e.toString()); } catch (Exception e) { Log.e("exception", e.toString()); } 
try to use this
keytool -list -v -keystore /home/marko/.android/debug.keystore just skip the -alias and -keypass attribute use only this main attribute
Run the following command to get your sha1: keytool -v -list -keystore "< debug.keystore path >" . check your debug.keystore path by windows-->preferences-->android-->build.
