    问题背景：

    Android 12客户项目中，切换访客时，launcher概率性发生crash。

    问题分析

    crash log：

    很明显crash是Launcher onCreate的时候调用LauncherAppWidgetHost.startListening，底层发生crash。

    User 10 must be unlocked for widgets to be available

    此log在framework/base下面AppWidgetServiceImpl.java中

    private void ensureGroupStateLoadedLocked(int userId, boolean enforceUserUnlockingOrUnlocked) {
        if (enforceUserUnlockingOrUnlocked && !isUserRunningAndUnlocked(userId)) {
            throw new IllegalStateException(
                    "User " + userId + " must be unlocked for widgets to be available");
        }
        if (enforceUserUnlockingOrUnlocked && isProfileWithLockedParent(userId)) {
            throw new IllegalStateException(
                    "Profile " + userId + " must have unlocked parent");
        }
}

    Log提示信息是因为没有解锁设备，去刷新widget导致此问题。

    Android 7.0引入了Direct Boot模式，当手机已经通电开机但是用户并有解锁锁屏的时候，Android N运行于一个安全的模式，也就是Dierect Boot模式。
    也就是这个时候不能去更新widget。如果launcher提前加载，需要特殊处理这个地方。

    解决方案

    在LauncherAppWidgetHost.startListening添加判断，如果没有解锁，则不进行相关处理，等解锁后再执行。

    private static final int FLAG_UNLOCK_DELAY_LISTENING = 1 << 4;
...
//添加解锁监听，解锁后判断是否要执行相应的逻辑startListening
screenListener = new ScreenListener(mContext);
screenListener.begin(new ScreenListener.ScreenStateListener() {
    @Override
    public void onUserPresent() {
        if (isUnlockDelayListening()){
			startListening();
        }
        mFlags &= ~FLAG_UNLOCK_DELAY_LISTENING;
    }
});
...
	@Override
    public void startListening() {
        if (WidgetsModel.GO_DISABLE_WIDGETS) {
            return;
        }
        final int userId = UserHandle.myUserId();
        //判断是否解锁,如果没有解锁，更新标志位，解锁后再执行。
        Log.d(TAG,"startListening# userId: "+userId);
        if(!StorageManager.isUserKeyUnlocked(userId)){
            mFlags |= FLAG_UNLOCK_DELAY_LISTENING;
            return;
        }else{
            mFlags &= ~FLAG_UNLOCK_DELAY_LISTENING;
        }
        mFlags |= FLAG_LISTENING;
        try {
            super.startListening();
        } catch (Exception e) {
            if (!Utilities.isBinderSizeError(e)) {
                throw new RuntimeException(e);
            }
            // We're willing to let this slide. The exception is being caused by the list of
            // RemoteViews which is being passed back. The startListening relationship will
            // have been established by this point, and we will end up populating the
            // widgets upon bind anyway. See issue 14255011 for more context.
        }
        // We go in reverse order and inflate any deferred widget
        for (int i = mViews.size() - 1; i >= 0; i--) {
            LauncherAppWidgetHostView view = mViews.valueAt(i);
            if (view instanceof DeferredAppWidgetHostView) {
                view.reInflate();
            }
        }
    }

    解决上述问题后，再次测试，又有其它地方的crash问题。报错依然是User 10 must be unlocked for widgets to be available。

    log分析：
    Launcher.inflateAppWidget填充widget信息时，调用底层方法报错。
    解决思路同上。
    在LauncherModel.startLoader中，bindWorkspace前进行判断。

    	public boolean startLoader() {
        // Enable queue before starting loader. It will get disabled in Launcher#finishBindingItems
        ItemInstallQueue.INSTANCE.get(mApp.getContext())
                .pauseModelPush(ItemInstallQueue.FLAG_LOADER_RUNNING);
        synchronized (mLock) {
            // Don't bother to start the thread if we know it's not going to do anything
            final Callbacks[] callbacksList = getCallbacks();
            if (callbacksList.length > 0) {
                // Clear any pending bind-runnables from the synchronized load process.
                for (Callbacks cb : callbacksList) {
                    MAIN_EXECUTOR.execute(cb::clearPendingBinds);
                }

                // If there is already one running, tell it to stop.
                stopLoader();
                LoaderResults loaderResults = new LoaderResults(
                        mApp, mBgDataModel, mBgAllAppsList, callbacksList);
                final int userId = UserHandle.myUserId();
                isUserRunningAndUnlocked = UserCache.INSTANCE.get(mApp.getContext()).isUserRunningAndUnlocked(userId);
                Log.d(TAG,"startLoader# userId: "+userId + " isUserRunningAndUnlocked: "+isUserRunningAndUnlocked);
                if (isUserRunningAndUnlocked){//添加判断，如果没有解锁，则不做处理，不开始bind桌面图标和widget
                    if (mModelLoaded && !mIsLoaderTaskRunning) {
                        // Divide the set of loaded items into those that we are binding synchronously,
                        // and everything else that is to be bound normally (asynchronously).
                        loaderResults.bindWorkspace();
                        // For now, continue posting the binding of AllApps as there are other
                        // issues that arise from that.
                        loaderResults.bindAllApps();
                        loaderResults.bindDeepShortcuts();
                        loaderResults.bindWidgets();
                        return true;
                    } else {
                        startLoaderForResults(loaderResults);
                    }
                }
            }
        }
        return false;
    }

    public void validateModelDataOnResume() {
        MODEL_EXECUTOR.getHandler().removeCallbacks(mDataValidationCheck);
        MODEL_EXECUTOR.post(mDataValidationCheck);

        final int userId = UserHandle.myUserId();
        boolean isUserRunningAndUnlocked = UserCache.INSTANCE.get(mApp.getContext()).isUserRunningAndUnlocked(userId);
        Log.d(TAG,"validateModelDataOnResume# userId: "+userId + " isUserRunningAndUnlocked: "+isUserRunningAndUnlocked + " this.isUserRunningAndUnlocked: "+this.isUserRunningAndUnlocked+" mLoaderTask "+mLoaderTask);
        if (!this.isUserRunningAndUnlocked && isUserRunningAndUnlocked){//onResume的时候，判断标志位，rebind
        Log.d(TAG,"validateModelDataOnResume isUserRunningAndUnlocked# widget not bind,need reload ");
            rebindCallbacks();
        }
    }

    致此，目前自测没有发现其它crash。如果有其它地方也有类似报错，同样处理就好了。

    后续总结

    此问题是因为launcher加载过早，让launcher在Direct Boot模式运行，提前调用widget相关方法导致。
    需要launcher自己处理widget相关的逻辑。
