本文主要是介绍10 展讯Sprd设置-电池-AppStateInfoCollector 接口介绍，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. AppStateInfoCollector 接口介绍

由于应用场景调用地方多样，所以该接口主要更新应用状态信息。这里重点 public接口的被调用状况

2. 实例化

package com.android.server.power;public class PowerController {// App state infoprivate AppStateInfoCollector mAppStateInfoCollector;// SystemServer.startOtherServices()public PowerController(Context context, IActivityManager activityManager) {...mAppStateInfoCollector = AppStateInfoCollector.getInstance(mContext);}

3. AppStateInfoCollector 接口介绍

3.1 单例模式调用

    public static AppStateInfoCollector getInstance(Context context) {synchronized (AppStateInfoCollector.class) {if (sInstance == null) {sInstance = new AppStateInfoCollector(context);}return sInstance;}}public AppStateInfoCollector(Context context) {mContext = context;}

3.2 AppStateInfoCollector.reportAppStateEventInfo

更新应用状态事件信息

    // 更新应用状态事件信息// return true: for new app state//     false: for otherspublic boolean reportAppStateEventInfo(String packageName, int userId, int stateEvent) {// 获取应用状态列表ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);//update mAppStateInfoListint index = mAppStateInfoList.indexOfKey(packageName);AppState appState = null;boolean ret = true;if (DEBUG) Slog.d(TAG, "- reportAppStateEventInfo() E -");if (index >= 0) {appState = mAppStateInfoList.valueAt(index);// 更新应用状态appState.updateAppState(stateEvent);ret = false;} else {// 新建一个应用状态appState = buildAppState(packageName, userId, stateEvent);mAppStateInfoList.put(packageName, appState);}return ret;}

3.3 AppStateInfoCollector.reportAppProcStateInfo

更新应用进程状态信息

    // 更新应用进程状态信息// return true: for new app state//     false: for otherspublic boolean reportAppProcStateInfo(String packageName, int uid, int procState) {int userId = UserHandle.getUserId(uid);ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);//update mAppStateInfoListint index = mAppStateInfoList.indexOfKey(packageName);AppState appState = null;boolean ret = true;if (DEBUG) Slog.d(TAG, "- reportAppProcStateInfo() E -");if (index >= 0) {appState = mAppStateInfoList.valueAt(index);// update procStateappState.mProcState = procState;if (uid != appState.mUid) appState.mUid = uid;ret = false;} else {if (DEBUG) Slog.d(TAG, "reportAppProcStateInfo: appName:" + packageName + " uid:" + uid + " is not exist, create it");appState = buildAppState(packageName, userId, Event.NONE);mAppStateInfoList.put(packageName, appState);}return ret;}

3.4 获取某个应用状态 AppStateInfoCollector.getAppState

根据uid或者包名，获取应用状态，非常实用，方便上层调用

    public AppState getAppState(String pkgName, int userId) {ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);int index = mAppStateInfoList.indexOfKey(pkgName);if (index >= 0) {AppState appState = mAppStateInfoList.valueAt(index);return appState;} else {return null;}}public AppState getAppState(int uid) {int userId = UserHandle.getUserId(uid);ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);for (int i=0;i<mAppStateInfoList.size();i++) {AppState appState = mAppStateInfoList.valueAt(i);if (appState.mUid == uid)return appState;}return null;}

3.5 AppStateInfoCollector.getCountOfActiveLaunchedApp

获取当前被启动的进程数量

    // to sync with mAppStateInfoList if this api is called by other thread ??public int getCountOfActiveLaunchedApps(int userId) {ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);int count = 0;for (int i=0;i<mAppStateInfoList.size();i++) {AppState appState = mAppStateInfoList.valueAt(i);if (appState.mLaunchCount > 0&& appState.mProcState != ActivityManager.PROCESS_STATE_CACHED_EMPTY&& appState.mProcState != ActivityManager.PROCESS_STATE_NONEXISTENT) {count++;}}return count;}

3.6 更新输入法状态信息

    // update the Input Method identify state of this apppublic void updateAppInputMethodState(String pkgName, boolean isInputMethod, int userId) {ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);int index = mAppStateInfoList.indexOfKey(pkgName);if (index >= 0) {AppState appState = mAppStateInfoList.valueAt(index);appState.mIsEnabledInputMethod = isInputMethod;}}// update the Input Method identify state of this apppublic void setDefaultInputMethodApp(String pkgName, int userId) {ArrayMap<String, AppState> mAppStateInfoList = getAppStateInfoList(userId);String mDefaultIMEAppName =  mDefaultIMEAppNameForUsers.get(userId);if (mDefaultIMEAppName != null&& mDefaultIMEAppName.equals(pkgName)) {return;}// clear orignalif (mDefaultIMEAppName != null) {int index = mAppStateInfoList.indexOfKey(mDefaultIMEAppName);if (index >= 0) {AppState appState = mAppStateInfoList.valueAt(index);appState.mIsDefaultInputMethod = false;}}// set newint index = mAppStateInfoList.indexOfKey(pkgName);if (index >= 0) {AppState appState = mAppStateInfoList.valueAt(index);appState.mIsDefaultInputMethod = true;}mDefaultIMEAppName = pkgName;mDefaultIMEAppNameForUsers.put(userId, mDefaultIMEAppName);}// if this app is a input Methodprivate boolean isEnabledIMEApp(String pkgName){if (pkgName == null) return false;IInputMethodManager service = IInputMethodManager.Stub.asInterface(ServiceManager.getService(Context.INPUT_METHOD_SERVICE));List<InputMethodInfo> inputMethods;try {inputMethods = service.getEnabledInputMethodList();} catch (RemoteException e) {return false;}if (inputMethods == null || inputMethods.size() == 0) return false;for (InputMethodInfo info : inputMethods){if (info == null || info.getPackageName() == null) continue;if (info.getPackageName().equals(pkgName)) return true;}return false;}

3.7 更新进程状态信息

    public void updateUidState(int uid, int uidState) {synchronized (mUidStateLock) {final int oldUidState = mUidState.get(uid, ActivityManager.PROCESS_STATE_CACHED_EMPTY);if (oldUidState != uidState) {// state changed, push updated rulesmUidState.put(uid, uidState);}}}public void removeUidState(int uid) {synchronized (mUidStateLock) {final int index = mUidState.indexOfKey(uid);if (index >= 0) {final int oldUidState = mUidState.valueAt(index);mUidState.removeAt(index);}}}

3.8 创建一个新的应用状态

    private AppState buildAppState(String packageName, int userId, int stateEvent) {ApplicationInfo app = null;int uid = 0;int procState = ActivityManager.PROCESS_STATE_CACHED_EMPTY;int flags = 0;try {app = AppGlobals.getPackageManager().getApplicationInfo(packageName, 0, userId);} catch (RemoteException e) {// can't happen; package manager is process-local}if (app != null) {uid = app.uid;flags = app.flags;synchronized (mUidStateLock) {procState = mUidState.get(uid, ActivityManager.PROCESS_STATE_CACHED_EMPTY);}}AppState retVal = new AppState(packageName, userId, uid, stateEvent, procState, flags);// check if is input methodretVal.mIsEnabledInputMethod = isEnabledIMEApp(packageName);//if (DEBUG) Slog.d(TAG, "- buildAppState() :" + packageName);return retVal;}

3.9 获取应用状态列表

    public ArrayMap<String, AppState> getAppStateInfoList(int userId) {ArrayMap<String, AppState> mAppStateInfoList = mUserAppStateInfoList.get(userId);if (mAppStateInfoList == null) {mAppStateInfoList = new ArrayMap<>();mUserAppStateInfoList.put(userId, mAppStateInfoList);}return mAppStateInfoList;}

即上述 reportAppStateEventInfo 和 reportAppProcStateInfo 和 updateUidState 作为外部调用接口，可以间接更新应用状态AppState
