堆栈打印跟踪Activity的启动过程(基于Android10.0.0-r41)，framework修改，去除第三方app的倒计时页面

1.打印异常堆栈

，查看Activity的onCreate如何回调的

        Log.i(TAG, "onCreate: ", new Exception());

编译

logcat -c清除日志缓存

logcat -s qfh过滤tag

跟踪堆栈调试发现，onCreate的回调大致从这里开始

走到这

往下走

那系统又是怎么调用handleLaunchActivity的？

系统Handler发消息以及处理消息

执行

从这里就能看出系统调用handleLaunchActivity的过程

2.去除第三方app的倒计时页面

查看位于最上层的activity，想办法去掉这个倒计时页面直接进入主页面

adb shell dumpsys activity activities | grep “Resumed”

查看最顶层

framework中修改，一般都是lanucher界面启动我们的第三方app

@Overridepublic void startActivity(Intent intent, @Nullable Bundle options) {//qfh addComponentName originCom = new ComponentName("com.example.myapplication2", "com.example.myapplication.WelcomeActivity");ComponentName targetCom = new ComponentName("com.example.myapplication2", "com.example.myapplication.MainActivity");if (intent.getComponent() != null && intent.getComponent().equals(originCom)) {intent.setComponent(targetCom);}//qfh endif (options != null) {startActivityForResult(intent, -1, options);} else {// Note we want to go through this call for compatibility with// applications that may have overridden the method.startActivityForResult(intent, -1);}}

这样就可以拦截我们想要拦截的Activity了

进到倒计时的下一个页面

3.模拟点击事件跳过首页进入主页

自定义一个方法处理点击按钮事件

@CallSuperprotected void onResume() {if (DEBUG_LIFECYCLE) Slog.v(TAG, "onResume " + this);dispatchActivityResumed();mActivityTransitionState.onResume(this);enableAutofillCompatibilityIfNeeded();if (mAutoFillResetNeeded) {if (!mAutoFillIgnoreFirstResumePause) {View focus = getCurrentFocus();if (focus != null && focus.canNotifyAutofillEnterExitEvent()) {// TODO: in Activity killed/recreated case, i.e. SessionLifecycleTest#// testDatasetVisibleWhileAutofilledAppIsLifecycled: the View's initial// window visibility after recreation is INVISIBLE in onResume() and next frame// ViewRootImpl.performTraversals() changes window visibility to VISIBLE.// So we cannot call View.notifyEnterOrExited() which will do nothing// when View.isVisibleToUser() is false.getAutofillManager().notifyViewEntered(focus);}}}notifyContentCaptureManagerIfNeeded(CONTENT_CAPTURE_RESUME);mCalled = true;//qfh addComponentName originCom = new ComponentName("com.example.myapplication2", "com.example.myapplication.TestWelcomeActivity");if (originCom.equals(getComponentName())){Log.i(TAG, "originCom.equals(getComponentName()) == true");mHandler.postDelayed(new Runnable() {@Overridepublic void run() {injectClick(420,52);}}, 1000);}//qfh end}

//qfh add //处理跳过按钮的坐标，模拟点击跳过广告页按钮private void injectClick(int x, int y) {MotionEvent downAction = MotionEvent.obtain(android.os.SystemClock.uptimeMillis(),android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, x, y, 0);dispatchTouchEvent(downAction);MotionEvent upAction = MotionEvent.obtain(android.os.SystemClock.uptimeMillis(),android.os.SystemClock.uptimeMillis(), MotionEvent.ACTION_UP, x, y, 0);mHandler.postDelayed(new Runnable() {@Overridepublic void run() {Log.i(TAG, "injectClick");dispatchTouchEvent(upAction);}},100);}//qfh end

注入一个点击事件

这样模拟点击事件跳过也可以的
