android4.4.4高通平台出现这个问题。

跟踪代码知道是Settings.System.putInt(resolver, Settings.System.SCREEN_BRIGHTNESS, brightness);出错。

从网上找到解决办法：

修改/frameworks/base/core/java/android/app/ContextImpl.java

private ContextImpl(ContextImpl container, ActivityThread mainThread, LoadedApk packageInfo, IBinder activityToken, UserHandle user, boolean restricted, Display display, Configuration overrideConfiguration)改成如下：

private ContextImpl(ContextImpl container, ActivityThread mainThread,
            LoadedApk packageInfo, IBinder activityToken, UserHandle user, boolean restricted,
            Display display, Configuration overrideConfiguration) {
        mOuterContext = this;

        mMainThread = mainThread;
        mActivityToken = activityToken;
        mRestricted = restricted;

        if (user == null) {
            user = Process.myUserHandle();
        }
        mUser = user;

        mPackageInfo = packageInfo;
        
        mResourcesManager = ResourcesManager.getInstance();
        mDisplay = display;
        mOverrideConfiguration = overrideConfiguration;

        final int displayId = getDisplayId();
        CompatibilityInfo compatInfo = null;
        if (container != null) {
            compatInfo = container.getDisplayAdjustments(displayId).getCompatibilityInfo();
        }
        if (compatInfo == null && displayId == Display.DEFAULT_DISPLAY) {
            compatInfo = packageInfo.getCompatibilityInfo();
        }
        mDisplayAdjustments.setCompatibilityInfo(compatInfo);
        mDisplayAdjustments.setActivityToken(activityToken);

        Resources resources = packageInfo.getResources(mainThread);
        if (resources != null) {
            if (activityToken != null
                    || displayId != Display.DEFAULT_DISPLAY
                    || overrideConfiguration != null
                    || (compatInfo != null && compatInfo.applicationScale
                            != resources.getCompatibilityInfo().applicationScale)) {
                resources = mResourcesManager.getTopLevelResources(
                        packageInfo.getResDir(), displayId,
                        overrideConfiguration, compatInfo, activityToken);
            }
        }
        mResources = resources;

        if (container != null) {
            mBasePackageName = container.mBasePackageName;
            mOpPackageName = container.mOpPackageName;
        } else {
            mBasePackageName = packageInfo.mPackageName;
            ApplicationInfo ainfo = packageInfo.getApplicationInfo();
            if (ainfo.uid == Process.SYSTEM_UID && ainfo.uid != Process.myUid()) {
                // Special case: system components allow themselves to be loaded in to other
                // processes.  For purposes of app ops, we must then consider the context as
                // belonging to the package of this process, not the system itself, otherwise
                // the package+uid verifications in app ops will fail.
                mOpPackageName = ActivityThread.currentPackageName();
            } else {
                mOpPackageName = mBasePackageName;
            }
        }
	mContentResolver = new ApplicationContentResolver(this, mainThread, user);
    }

重新编译framework
