一、应用标题描述。
1、应用程序版本。
mAppVersion.setText(getActivity().getString(R.string.version_text,//版本 <xliff:g id="VERSION_NUM">%1$s</xliff:g> String.valueOf(pkgInfo.versionName))
二、强制停止、停用/启用/卸载。
1、强制停止。
不可点击情况:1、应用含有设备文件、2、当前应用已停止。
点击操作逻辑:
ActivityManager am = (ActivityManager)getActivity().getSystemService( Context.ACTIVITY_SERVICE); am.forceStopPackage(pkgName); mState.invalidatePackage(pkgName); ApplicationsState.AppEntry newEnt = mState.getEntry(pkgName); if (newEnt != null) { mAppEntry = newEnt; } checkForceStop();
2、停用/启用/卸载。
private void initUninstallButtons() { mUpdatedSysApp = (mAppEntry.info.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0; // 有些系统应用是可以更新的,如果用户自己下载了一个系统的应用来更新了原来的, // 它就不是系统应用啦,这个就是判断这种情况的 //FLAG_UPDATED_SYSTEM_APP就是一个可升级的系统应用啦,但如果用户把它升级了,那么,就应该把它当成是用户的应用 boolean enabled = true; if (mUpdatedSysApp) {//表示是系统程序,但用户更新过,也算是用户安装的程序 mUninstallButton.setText(R.string.app_factory_reset);//卸载更新 boolean specialDisable = false; if ((mAppEntry.info.flags & ApplicationInfo.FLAG_SYSTEM) != 0) { specialDisable = handleDisableable(mSpecialDisableButton); mSpecialDisableButton.setOnClickListener(this); } mMoreControlButtons.setVisibility(specialDisable ? View.VISIBLE : View.GONE); } else { mMoreControlButtons.setVisibility(View.GONE); if ((mAppEntry.info.flags & ApplicationInfo.FLAG_SYSTEM) != 0) { enabled = handleDisableable(mUninstallButton); } else if ((mPackageInfo.applicationInfo.flags & ApplicationInfo.FLAG_INSTALLED) == 0 && mUserManager.getUsers().size() >= 2) { // When we have multiple users, there is a separate menu // to uninstall for all users. mUninstallButton.setText(R.string.uninstall_text); enabled = false; } else { mUninstallButton.setText(R.string.uninstall_text); } } // If this is a device admin, it can't be uninstall or disabled. // We do this here so the text of the button is still set correctly. if (mDpm.packageHasActiveAdmins(mPackageInfo.packageName)) { enabled = false; } mUninstallButton.setEnabled(enabled); if (enabled) { // Register listener mUninstallButton.setOnClickListener(this); } }
1、是否是用户更新的系统程序
2、如果是,显示三个button。第一行“强制停止”,“卸载更新”。第二行“null”,“停用/启用”。
如果否,显示两个button。第一行“强制停止”,“停用/启用”
如果是用户更新的系统程序,则:
否则:
显示停用、启用还是卸载?
如果是系统应用,则 在【mAppEntry.info.enabled || mHomePackages.contains(mAppEntry.info.packageName) || isThisASystemPackage()】时显示“停用” 否则显示“启用” 如果是非系统应用 显示卸载。
按钮是否可点击?
不可可点击的情况:应用含有系统签名 或者 应用中含有设备文件。点击逻辑
return new AlertDialog.Builder(getActivity()) .setTitle(getActivity().getText(R.string.app_factory_reset_dlg_title))//要卸载更新吗? .setIconAttribute(android.R.attr.alertDialogIcon) .setMessage(getActivity().getText(R.string.app_factory_reset_dlg_text))//系统将会卸载此 Android 系统应用的所有相关更新。 .setPositiveButton(R.string.dlg_ok, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { // Clear user data here getOwner().uninstallPkg(getOwner().mAppEntry.info.packageName, false, false); } }) .setNegativeButton(R.string.dlg_cancel, null) .create(); 点击处理逻辑 if ((mAppEntry.info.flags & ApplicationInfo.FLAG_SYSTEM) != 0) { if (mAppEntry.info.enabled) { showDialogInner(DLG_DISABLE, 0);//停用 } else { new DisableChanger(this, mAppEntry.info, PackageManager.COMPONENT_ENABLED_STATE_DEFAULT) .execute((Object)null);//启用 } } else if ((mAppEntry.info.flags & ApplicationInfo.FLAG_INSTALLED) == 0) { uninstallPkg(packageName, true, false);//卸载 } else { uninstallPkg(packageName, false, false); }3、显示通知。
String packageName = mAppEntry.info.packageName; INotificationManager nm = INotificationManager.Stub.asInterface( ServiceManager.getService(Context.NOTIFICATION_SERVICE)); try { final boolean enable = mNotificationSwitch.isChecked(); nm.setNotificationsEnabledForPackage(packageName, mAppEntry.info.uid, enabled); } catch (android.os.RemoteException ex) { mNotificationSwitch.setChecked(!enabled); // revert }
三、存储。
1、总计:mAppEntry.size 2、应用: codeSize = mAppEntry.codeSize; if (Environment.isExternalStorageEmulated()) { codeSize += mAppEntry.externalCodeSize; } 3、USB存储(应用) = mAppEntry.externalCodeSize 4、数据 = long dataSize = mAppEntry.dataSize; if (Environment.isExternalStorageEmulated()) { dataSize += mAppEntry.externalDataSize; } 5、SD卡; mAppEntry.externalDataSize 5.1、移动sd卡。 初始化 private void initMoveButton() { if (Environment.isExternalStorageEmulated()) { mMoveAppButton.setVisibility(View.INVISIBLE); return; } boolean dataOnly = false; dataOnly = (mPackageInfo == null) && (mAppEntry != null); boolean moveDisable = true; if (dataOnly) { mMoveAppButton.setText(R.string.move_app); } else if ((mAppEntry.info.flags & ApplicationInfo.FLAG_EXTERNAL_STORAGE) != 0) { mMoveAppButton.setText(R.string.move_app_to_internal); // Always let apps move to internal storage from sdcard. moveDisable = false; } else { mMoveAppButton.setText(R.string.move_app_to_sdcard); mCanBeOnSdCardChecker.init(); moveDisable = !mCanBeOnSdCardChecker.check(mAppEntry.info); } if (moveDisable) { mMoveAppButton.setEnabled(false); } else { mMoveAppButton.setOnClickListener(this); mMoveAppButton.setEnabled(true); } } 点击逻辑 if (mPackageMoveObserver == null) { mPackageMoveObserver = new PackageMoveObserver(); } int moveFlags = (mAppEntry.info.flags & ApplicationInfo.FLAG_EXTERNAL_STORAGE) != 0 ? PackageManager.MOVE_INTERNAL : PackageManager.MOVE_EXTERNAL_MEDIA; mMoveInProgress = true; refreshButtons(); mPm.movePackage(mAppEntry.info.packageName, mPackageMoveObserver, moveFlags); 5.2、清楚数据。 初始化: private void initDataButtons() { // If the app doesn't have its own space management UI // And it's a system app that doesn't allow clearing user data or is an active admin // Then disable the Clear Data button. if (mAppEntry.info.manageSpaceActivityName == null && ((mAppEntry.info.flags&(ApplicationInfo.FLAG_SYSTEM | ApplicationInfo.FLAG_ALLOW_CLEAR_USER_DATA)) == ApplicationInfo.FLAG_SYSTEM || mDpm.packageHasActiveAdmins(mPackageInfo.packageName))) { mClearDataButton.setText(R.string.clear_user_data_text); mClearDataButton.setEnabled(false); mCanClearData = http://www.mamicode.com/false;>四、缓存。
1、缓存: mAppEntry.cacheSize + mAppEntry.externalCacheSize; 2、点击清楚缓存 if (mClearCacheObserver == null) { mClearCacheObserver = new ClearCacheObserver(); } mPm.deleteApplicationCacheFiles(packageName, mClearCacheObserver);
五、默认启动。
1、默认启动 得到优先设置项mPm.getPreferredActivities(intentList, prefActList, packageName); 是否含有usb默认项设置:hasUsbDefaults = mUsbManager.hasDefaults(packageName, UserHandle.myUserId()); 是否绑定权限:boolean hasBindAppWidgetPermission = mAppWidgetManager.hasBindAppWidgetPermission(mAppEntry.info.packageName); 2、清楚默认设置 <span style="white-space:pre"> </span> mPm.clearPackagePreferredActivities(packageName); try { mUsbManager.clearDefaults(packageName, UserHandle.myUserId()); } catch (RemoteException e) { Log.e(TAG, "mUsbManager.clearDefaults", e); } mAppWidgetManager.setBindAppWidgetPermission(packageName, false); TextView autoLaunchTitleView = (TextView) mRootView.findViewById(R.id.auto_launch_title);//无默认设置。 TextView autoLaunchView = (TextView) mRootView.findViewById(R.id.auto_launch); resetLaunchDefaultsUi(autoLaunchTitleView, autoLaunchView);
