计算IMEI

private String changeIMEI() {// calculator IMEIint r1 = 1000000 + new Random().nextInt(10000000);int r2 = 1000000 + new Random().nextInt(10000000);String input = r1 + "" + r2;char[] ch = input.toCharArray();int a = 0, b = 0;for (int i = 0; i < ch.length; i++) {int tt = Integer.parseInt(ch[i] + "");if (i % 2 == 0) {a = a + tt;} else {int temp = tt * 2;b = b + temp / 10 + temp % 10;}}int last = (a + b) % 10;if (last == 0) {last = 0;} else {last = 10 - last;}return input + last;}

清除 Userdata

class ClearUserDataObserver extends IPackageDataObserver.Stub {public void onRemoveCompleted(final String packageName,final boolean succeeded) {Log.v("tag", packageName + "----> " + succeeded);}}private void ClearUserData() {if (pakagMap == null) {initData();}Set<String> pkgSet = (Set<String>) pakagMap.keySet();for (String pname : pkgSet) {ClearUserDataObserver mClearDataObserver = null;if (mClearDataObserver == null) {mClearDataObserver = new ClearUserDataObserver();}ActivityManager am = (ActivityManager) MainActivity.this.getSystemService(Context.ACTIVITY_SERVICE);boolean res = am.clearApplicationUserData(pname, mClearDataObserver);}WriteIMEI();}
