怎么在smali中修改才能注释java代码中的一行

i want to delete the 580th and 581th line in the java code below. this file is in system/framework/services.jar in android devices, so the steps i did are:

1. decompile jar to smali

2. change the smali file

3. recompile the smali file to dex file

4. pack it into services.jar.

5. push services.jar into android mobile phone

The question is on step2, how to change the smali file, i try to delete :line580 and the code below it, but it doesn"t work, when compiling, a nullPointerExecption thrown...and i can see /*error*/ in jd-gui tool

Somebody please give me some advices, i"m totally new to smali, thanks in advance.

100分相送，望大神指点，谢谢

The java code is:

568 public void registerUiTestAutomationService(IBinder owner,

569 IAccessibilityServiceClient serviceClient,

570 AccessibilityServiceInfo accessibilityServiceInfo) {

571 mSecurityPolicy.enforceCallingPermission(Manifest.permission.RETRIEVE_WINDOW_CONTENT,

572 FUNCTION_REGISTER_UI_TEST_AUTOMATION_SERVICE);

573

574 accessibilityServiceInfo.setComponentName(sFakeAccessibilityServiceComponentName);

575

576 synchronized (mLock) {

577 UserState userState = getCurrentUserStateLocked();

578

579 if (userState.mUiAutomationService != null) {

580 throw new IllegalStateException("UiAutomationService " + serviceClient

581 + "already registered!");

582 }

583

584 try {

585 owner.linkToDeath(userState.mUiAutomationSerivceOnwerDeathRecipient, 0);

586 } catch (RemoteException re) {

587 Slog.e(LOG_TAG, "Couldn"t register for the death of a"

588 + " UiTestAutomationService!", re);

589 return;

590 }

591

592 userState.mUiAutomationServiceOwner = owner;

593 userState.mUiAutomationServiceClient = serviceClient;

594

595 // Set the temporary state.

596 userState.mIsAccessibilityEnabled = true;

597 userState.mIsTouchExplorationEnabled = false;

598 userState.mIsEnhancedWebAccessibilityEnabled = false;

599 userState.mIsDisplayMagnificationEnabled = false;

600 userState.mInstalledServices.add(accessibilityServiceInfo);

601 userState.mEnabledServices.clear();

602 userState.mEnabledServices.add(sFakeAccessibilityServiceComponentName);

603 userState.mTouchExplorationGrantedServices.add(sFakeAccessibilityServiceComponentName);

604

605 // Use the new state instead of settings.

606 onUserStateChangedLocked(userState);

607 }

608 }

The smali code after decompiling:

怎样把smali文件转换为java文件

可以先把smali转化为dex文件，然后再用 dex2jar转化一次。我之前也遇到过跟你一样的情况就是这么处理的。祝你好运！

JAVA转换成smali语法

if-eq改成if-ne

if-ne 改成 if-eq

if-eqz改成 if-nez

if-nez 改成if-eqz
