Reprinted please indicate the source: http://blog.csdn.net/droyon/article/details/39891355

1. All, in progress, disabled, USB storage device, and downloaded tab page element annotation.

1. Icon.

boolean ensureIconLocked(Context context, PackageManager pm) {            if (this.icon == null) {                if (this.apkFile.exists()) {                    this.icon = this.info.loadIcon(pm);                    return true;                } else {                    this.mounted = false;                    this.icon = context.getResources().getDrawable(                            com.android.internal.R.drawable.sym_app_on_sd_unavailable_icon);                }            } else if (!this.mounted) {                // If the app wasn't mounted but is now mounted, reload                // its icon.                if (this.apkFile.exists()) {                    this.mounted = true;                    this.icon = this.info.loadIcon(pm);                    return true;                }            }            return false;        }    }

2. Application name.

void ensureLabel(Context context) {            if (this.label == null || !this.mounted) {                if (!this.apkFile.exists()) {                    this.mounted = false;                    this.label = info.packageName;                } else {                    this.mounted = true;                    CharSequence label = info.loadLabel(context.getPackageManager());                    this.label = label != null ? label.toString() : info.packageName;                }            }        }

3. Size.

ApplicationsState.AppFilter filterObj;            Comparator<AppEntry> comparatorObj;            private int mWhichSize = SIZE_TOTAL;            boolean emulated = Environment.isExternalStorageEmulated();            if (emulated) {                mWhichSize = SIZE_TOTAL;            } else {                mWhichSize = SIZE_INTERNAL;            }            switch (mFilterMode) {                case FILTER_APPS_THIRD_PARTY:                    filterObj = ApplicationsState.THIRD_PARTY_FILTER;                    break;                case FILTER_APPS_SDCARD:                    filterObj = ApplicationsState.ON_SD_CARD_FILTER;                    if (!emulated) {                        mWhichSize = SIZE_EXTERNAL;                    }                    break;                case FILTER_APPS_DISABLED:                    filterObj = ApplicationsState.DISABLED_FILTER;                    break;                default:                    filterObj = ApplicationsState.ALL_ENABLED_FILTER;                    break;            }

void updateSizeText(CharSequence invalidSizeStr, int whichSize) {        if (ManageApplications.DEBUG) Log.i(ManageApplications.TAG, "updateSizeText of " + entry.label + " " + entry                + ": " + entry.sizeStr);        if (entry.sizeStr != null) {            switch (whichSize) {                case ManageApplications.SIZE_INTERNAL:                    appSize.setText(entry.internalSizeStr);                    break;                case ManageApplications.SIZE_EXTERNAL:                    appSize.setText(entry.externalSizeStr);                    break;                default:                    appSize.setText(entry.sizeStr);                    break;            }        } else if (entry.size == ApplicationsState.SIZE_INVALID) {            appSize.setText(invalidSizeStr);        }    }

Different tab pages are calculated based on whether the Simulated Storage Area is included.

For details about the calculation method of the application size, refer to the attributes and terms of the application settings.

4. 5. Space.

The space here is the space occupied by applications and belongs to the storage device area of the fuselage. Calculation method:

try {                        final long[] stats = mContainerService.getFileSystemStats(                                Environment.getExternalStorageDirectory().getPath());                        mTotalStorage = stats[0];                        mFreeStorage = stats[1];                    } catch (RemoteException e) {                        Log.w(TAG, "Problem in container service", e);                    }

2. The interface element annotation is being executed.

1. Icon.

public Drawable loadIcon(Context context, RunningState state) {            if (mPackageInfo != null) {                return mPackageInfo.loadIcon(state.mPm);            }            return null;        }

2. Name.

void ensureLabel(PackageManager pm) {            if (mLabel != null) {                return;            }                        try {                ApplicationInfo ai = pm.getApplicationInfo(mProcessName,                        PackageManager.GET_UNINSTALLED_PACKAGES);                if (ai.uid == mUid) {                    mDisplayLabel = ai.loadLabel(pm);                    mLabel = mDisplayLabel.toString();                    mPackageInfo = ai;                    return;                }            } catch (PackageManager.NameNotFoundException e) {            }                        // If we couldn't get information about the overall            // process, try to find something about the uid.            String[] pkgs = pm.getPackagesForUid(mUid);                        // If there is one package with this uid, that is what we want.            if (pkgs.length == 1) {                try {                    ApplicationInfo ai = pm.getApplicationInfo(pkgs[0],                            PackageManager.GET_UNINSTALLED_PACKAGES);                    mDisplayLabel = ai.loadLabel(pm);                    mLabel = mDisplayLabel.toString();                    mPackageInfo = ai;                    return;                } catch (PackageManager.NameNotFoundException e) {                }            }                        // If there are multiple, see if one gives us the official name            // for this uid.            for (String name : pkgs) {                try {                    PackageInfo pi = pm.getPackageInfo(name, 0);                    if (pi.sharedUserLabel != 0) {                        CharSequence nm = pm.getText(name,                                pi.sharedUserLabel, pi.applicationInfo);                        if (nm != null) {                            mDisplayLabel = nm;                            mLabel = nm.toString();                            mPackageInfo = pi.applicationInfo;                            return;                        }                    }                } catch (PackageManager.NameNotFoundException e) {                }            }                        // If still don't have anything to display, just use the            // service info.            if (mServices.size() > 0) {                ApplicationInfo ai = mServices.values().iterator().next()                        .mServiceInfo.applicationInfo;                mPackageInfo = ai;                mDisplayLabel = mPackageInfo.loadLabel(pm);                mLabel = mDisplayLabel.toString();                return;            }                        // Finally... whatever, just pick the first package's name.            try {                ApplicationInfo ai = pm.getApplicationInfo(pkgs[0],                        PackageManager.GET_UNINSTALLED_PACKAGES);                mDisplayLabel = ai.loadLabel(pm);                mLabel = mDisplayLabel.toString();                mPackageInfo = ai;                return;            } catch (PackageManager.NameNotFoundException e) {            }        }

3. Details of the services contained and the entry into the city.

mergedItem = new MergedItem(pi.mUserId);                    for (ServiceItem si : pi.mServices.values()) {//构建内部mServices，mProcesInfo。                        mergedItem.mServices.add(si);                        si.mMergedItem = mergedItem;                    }                    mergedItem.mProcess = pi;                    mergedItem.mOtherProcesses.clear();                    for (int mpi=firstProc; mpi<(mProcessItems.size()-1); mpi++) {                        mergedItem.mOtherProcesses.add(mProcessItems.get(mpi));                    }

setDescription(context, (mProcess.mPid > 0 ? 1 : 0) + mOtherProcesses.size(),                            mServices.size());

4. Size.

ong[] pss = ActivityManagerNative.getDefault()                    .getProcessPss(pids);boolean updateSize(Context context, long pss, int curSeq) {            mSize = pss * 1024;            if (mCurSeq == curSeq) {                String sizeStr = Formatter.formatShortFileSize(                        context, mSize);                if (!sizeStr.equals(mSizeStr)){                    mSizeStr = sizeStr;                    // We update this on the second tick where we update just                    // the text in the current items, so no need to say we                    // changed here.                    return false;                }            }            return false;        }

5. execution time.

long activeSince = service.restarting == 0 ? service.activeSince : -1;服务activie的时间ai.mFirstRunTime = activeSince/*item.mActiveSince*/;DateUtils.formatElapsedTime(builder,                            (SystemClock.elapsedRealtime()-mFirstRunTime)/1000)

6. 7. space computing in progress. Memory space.
