Android12 launcher3隐藏某个应用的图标
1.前言:
之前在做AOSP定制的时候需要隐藏某些App的图标，或者默认不显示某个定制的App图标，这样可以让用户感觉不到已经安装了某个App,或者在做系统定制的时候需要修改桌面icon,有些系统的App图标默认不需要显示，因为原生的系统App很多，有些用户又不需要全部在桌面显示，这时候就需要隐藏某些App的图标了，直接上代码。
2.源码路径如下：
/packages/apps/Launcher3/src/com/android/launcher3/model/LoaderTask
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
// This builds the icon bitmaps.
mBgAllAppsList.add(new AppInfo(app, user, quietMode), app);
}
allActivityList.addAll(apps);
}
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
// get all active sessions and add them to the all apps list
for (PackageInstaller.SessionInfo info :
mSessionHelper.getAllVerifiedSessions()) {
mBgAllAppsList.addPromiseApp(mApp.getContext(),
PackageInstallInfo.fromInstallingState(info));
}
}
for (AppInfo item : mBgDataModel.cachedPredictedItems) {
List<LauncherActivityInfo> l = mLauncherApps.getActivityList(
item.componentName.getPackageName(), item.user);
for (LauncherActivityInfo info : l) {
boolean quietMode = mUserManagerState.isUserQuiet(item.user);
mBgAllAppsList.add(new AppInfo(info, item.user, quietMode), info);
}
}
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_ENABLED,
mUserManagerState.isAnyProfileQuietModeEnabled());
mBgAllAppsList.setFlags(FLAG_HAS_SHORTCUT_PERMISSION,
hasShortcutsPermission(mApp.getContext()));
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_CHANGE_PERMISSION,
mApp.getContext().checkSelfPermission("android.permission.MODIFY_QUIET_MODE")
== PackageManager.PERMISSION_GRANTED);
mBgAllAppsList.getAndResetChangeFlag();
return allActivityList;
}
3.修改的核心方法如下：
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
// This builds the icon bitmaps.
String pkg = app.getComponentName().getPackageName();
if (pkg.equals("com.android.calendar")
|| pkg.equals("com.android.deskclock")
|| pkg.equals("com.android.dialer")
|| pkg.equals("com.android.quicksearchbox")
|| pkg.equals("com.android.contacts")
|| pkg.equals("com.android.camera2")
|| pkg.equals("com.android.email")
|| pkg.equals("com.android.calculator2")
|| pkg.equals("org.chromium.webview_shell")
|| pkg.equals("com.android.gallery3d")
|| pkg.equals("com.android.music")
|| pkg.equals("com.android.browser")
|| pkg.equals("com.google.android.browser")) {
continue;
}
mBgAllAppsList.add(new AppInfo(app, user, quietMode), app);
}
allActivityList.addAll(apps);
}
4.隐藏系统通讯录图标：
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
// This builds the icon bitmaps.
String pkg = app.getComponentName().getPackageName();
if (pkg.equals("com.android.contacts")) {
continue;
}
mBgAllAppsList.add(new AppInfo(app, user, quietMode), app);
}
allActivityList.addAll(apps);
}
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
// get all active sessions and add them to the all apps list
for (PackageInstaller.SessionInfo info :
mSessionHelper.getAllVerifiedSessions()) {
mBgAllAppsList.addPromiseApp(mApp.getContext(),
PackageInstallInfo.fromInstallingState(info));
}
}
for (AppInfo item : mBgDataModel.cachedPredictedItems) {
List<LauncherActivityInfo> l = mLauncherApps.getActivityList(
item.componentName.getPackageName(), item.user);
for (LauncherActivityInfo info : l) {
boolean quietMode = mUserManagerState.isUserQuiet(item.user);
mBgAllAppsList.add(new AppInfo(info, item.user, quietMode), info);
}
}
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_ENABLED,
mUserManagerState.isAnyProfileQuietModeEnabled());
mBgAllAppsList.setFlags(FLAG_HAS_SHORTCUT_PERMISSION,
hasShortcutsPermission(mApp.getContext()));
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_CHANGE_PERMISSION,
mApp.getContext().checkSelfPermission("android.permission.MODIFY_QUIET_MODE")
== PackageManager.PERMISSION_GRANTED);
mBgAllAppsList.getAndResetChangeFlag();
return allActivityList;
}
5.隐藏系统相册图标：
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
// This builds the icon bitmaps.
String pkg = app.getComponentName().getPackageName();
if (pkg.equals("com.android.gallery3d")
|| pkg.equals("com.android.camera2")) {
continue;
}
mBgAllAppsList.add(new AppInfo(app, user, quietMode), app);
}
allActivityList.addAll(apps);
}
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
// get all active sessions and add them to the all apps list
for (PackageInstaller.SessionInfo info :
mSessionHelper.getAllVerifiedSessions()) {
mBgAllAppsList.addPromiseApp(mApp.getContext(),
PackageInstallInfo.fromInstallingState(info));
}
}
for (AppInfo item : mBgDataModel.cachedPredictedItems) {
List<LauncherActivityInfo> l = mLauncherApps.getActivityList(
item.componentName.getPackageName(), item.user);
for (LauncherActivityInfo info : l) {
boolean quietMode = mUserManagerState.isUserQuiet(item.user);
mBgAllAppsList.add(new AppInfo(info, item.user, quietMode), info);
}
}
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_ENABLED,
mUserManagerState.isAnyProfileQuietModeEnabled());
mBgAllAppsList.setFlags(FLAG_HAS_SHORTCUT_PERMISSION,
hasShortcutsPermission(mApp.getContext()));
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_CHANGE_PERMISSION,
mApp.getContext().checkSelfPermission("android.permission.MODIFY_QUIET_MODE")
== PackageManager.PERMISSION_GRANTED);
mBgAllAppsList.getAndResetChangeFlag();
return allActivityList;
}
6.隐藏系统webview图标：
这里有个坑需要注意！！！
这里有个坑需要注意！！！
这里有个坑需要注意！！！
重要的事说三遍，webview在系统应用中可能会有多个包名，如果只是单纯添加某一个会不生效，本人是做过多次测试和修改，最后是经过查找资料和询问大佬实践多次才解决此问题，当时一度以为代码出现问题快emo了，最后才发现是系统webview可能安装了多个应用，导致存在多个包名，使用下面的方式进行过滤，感兴趣的朋友自己尝试.
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
// This builds the icon bitmaps.
String pkg = app.getComponentName().getPackageName();
if (pkg.equals("com.android.browser")
|| pkg.equals("com.android.webview")
|| pkg.equals("org.chromium.webview_shell")
|| pkg.equals("com.google.android.browser")) {
continue;
}
mBgAllAppsList.add(new AppInfo(app, user, quietMode), app);
}
allActivityList.addAll(apps);
}
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
// get all active sessions and add them to the all apps list
for (PackageInstaller.SessionInfo info :
mSessionHelper.getAllVerifiedSessions()) {
mBgAllAppsList.addPromiseApp(mApp.getContext(),
PackageInstallInfo.fromInstallingState(info));
}
}
for (AppInfo item : mBgDataModel.cachedPredictedItems) {
List<LauncherActivityInfo> l = mLauncherApps.getActivityList(
item.componentName.getPackageName(), item.user);
for (LauncherActivityInfo info : l) {
boolean quietMode = mUserManagerState.isUserQuiet(item.user);
mBgAllAppsList.add(new AppInfo(info, item.user, quietMode), info);
}
}
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_ENABLED,
mUserManagerState.isAnyProfileQuietModeEnabled());
mBgAllAppsList.setFlags(FLAG_HAS_SHORTCUT_PERMISSION,
hasShortcutsPermission(mApp.getContext()));
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_CHANGE_PERMISSION,
mApp.getContext().checkSelfPermission("android.permission.MODIFY_QUIET_MODE")
== PackageManager.PERMISSION_GRANTED);
mBgAllAppsList.getAndResetChangeFlag();
return allActivityList;
}
7.封装工具类：
在源码路径添加：/packages/apps/Launcher3/src/com/android/launcher3/util/HideAppIconUtils
HideAppIconUtils工具类
package com.android.launcher3.util;
import java.util.LinkedList;
import java.util.List;
/**
* @author: smile
* @date: 2025/2/24 23:45
* @desc: 隐藏指定App的图标
*/
public class HideAppIconUtils {
private static final List<String> mPackageMap = new LinkedList<>();
private HideAppIconUtils() {
addHideAppList();
}
//需要隐藏的系统App包名,添加到这里
private void addHideAppList() {
mPackageMap.add("com.android.calendar");
mPackageMap.add("com.android.deskclock");
mPackageMap.add("com.android.quicksearchbox");
mPackageMap.add("com.android.contacts");
mPackageMap.add("com.android.camera2");
mPackageMap.add("com.android.email");
mPackageMap.add("com.android.calculator2");
mPackageMap.add("com.android.gallery3d");
mPackageMap.add("com.android.music");
mPackageMap.add("org.chromium.webview_shell");
mPackageMap.add("com.android.browser");
mPackageMap.add("com.google.android.browser");
}
private static class HideAppIconUtilsHolder {
private static final HideAppIconUtils INSTALL = new HideAppIconUtils();
}
public static HideAppIconUtils getInstall() {
return HideAppIconUtilsHolder.INSTALL;
}
public boolean isHidedApkPackageName(String apkPkg) {
return mPackageMap.contains(apkPkg);
}
}
}
8.更新时修改Launche3：
源码路径：/packages/apps/Launcher3/src/com/android/launcher3/model/PackageUpdatedTask
PackageUpdatedTask类代码如下：此类看源码注释就是说明在App包名发生改变或者桌面App发生变化时有一个线程Handler会更新或者删除相应的内容.

// Collections.sort(appInfos, mAppNameComparator);
ArrayList<Pair<ItemInfo, Object>> installQueue = new ArrayList<>();
for (AppInfo info : appInfos) {
installQueue.add(Pair.create((ItemInfo) info, null));
}
app.getModel().addAndBindAddedWorkspaceItems(installQueue);
}
}
// add end
}
9.更新时关键修改如下：
@Override
public void execute(LauncherAppState app, BgDataModel dataModel, AllAppsList appsList) {
final Context context = app.getContext();
final IconCache iconCache = app.getIconCache();
final String[] packages = mPackages;
final int N = packages.length;
FlagOp flagOp = FlagOp.NO_OP;

switch (mOp) {
case OP_ADD: {
for (int i = 0; i < N; i++) {
if (DEBUG) Log.d(TAG, "mAllAppsList.addPackage " + packages[i]);
String pkg = packages[i];
if ("com.android.calendar".equals(pkg)

continue;
}
iconCache.updateIconsForPkg(packages[i], mUser);
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
appsList.removePackage(packages[i], mUser);
}
appsList.addPackage(context, packages[i], mUser);
// Automatically add homescreen icon for work profile apps for below O device.
if (!Utilities.ATLEAST_OREO && !Process.myUserHandle().equals(mUser)) {
SessionCommitReceiver.queueAppIconAddition(context, packages[i], mUser);
}
}
flagOp = FlagOp.removeFlag(WorkspaceItemInfo.FLAG_DISABLED_NOT_AVAILABLE);
break;
}
case OP_UPDATE:
try (SafeCloseable t =
appsList.trackRemoves(a -> removedComponents.add(a.componentName))) {
for (int i = 0; i < N; i++) {
if (DEBUG) Log.d(TAG, "mAllAppsList.updatePackage " + packages[i]);

continue;
}
iconCache.updateIconsForPkg(packages[i], mUser);
appsList.updatePackage(context, packages[i], mUser);
app.getWidgetCache().removePackage(packages[i], mUser);
}
}
// Since package was just updated, the target must be available now.
flagOp = FlagOp.removeFlag(WorkspaceItemInfo.FLAG_DISABLED_NOT_AVAILABLE);
break;
case OP_REMOVE: {
for (int i = 0; i < N; i++) {
FileLog.d(TAG, "Removing app icon" + packages[i]);
iconCache.removeIconsForPkg(packages[i], mUser);
}
// Fall through
}
case OP_UNAVAILABLE:
for (int i = 0; i < N; i++) {
if (DEBUG) Log.d(TAG, "mAllAppsList.removePackage " + packages[i]);

break;
case OP_SUSPEND:
case OP_UNSUSPEND:
flagOp = mOp == OP_SUSPEND ?
FlagOp.addFlag(WorkspaceItemInfo.FLAG_DISABLED_SUSPENDED) :
FlagOp.removeFlag(WorkspaceItemInfo.FLAG_DISABLED_SUSPENDED);
if (DEBUG) Log.d(TAG, "mAllAppsList.(un)suspend " + N);
appsList.updateDisabledFlags(matcher, flagOp);
break;
case OP_USER_AVAILABILITY_CHANGE: {
UserManagerState ums = new UserManagerState();
ums.init(UserCache.INSTANCE.get(context),
context.getSystemService(UserManager.class));
flagOp = ums.isUserQuiet(mUser)
? FlagOp.addFlag(WorkspaceItemInfo.FLAG_DISABLED_QUIET_USER)
: FlagOp.removeFlag(WorkspaceItemInfo.FLAG_DISABLED_QUIET_USER);
// We want to update all packages for this user.
matcher = ItemInfoMatcher.ofUser(mUser);
appsList.updateDisabledFlags(matcher, flagOp);
// We are not synchronizing here, as int operations are atomic
appsList.setFlags(FLAG_QUIET_MODE_ENABLED, ums.isAnyProfileQuietModeEnabled());
break;
}
}
10.工具类的使用：
private List<LauncherActivityInfo> loadAllApps() {
final List<UserHandle> profiles = mUserCache.getUserProfiles();
List<LauncherActivityInfo> allActivityList = new ArrayList<>();
// Clear the list of apps
mBgAllAppsList.clear();
List<IconRequestInfo<AppInfo>> iconRequestInfos = new ArrayList<>();
for (UserHandle user : profiles) {
// Query for the set of apps
final List<LauncherActivityInfo> apps = mLauncherApps.getActivityList(null, user);
// Fail if we don't have any apps
// TODO: Fix this. Only fail for the current user.
if (apps == null || apps.isEmpty()) {
return allActivityList;
}
boolean quietMode = mUserManagerState.isUserQuiet(user);
// Create the ApplicationInfos
for (int i = 0; i < apps.size(); i++) {
LauncherActivityInfo app = apps.get(i);
AppInfo appInfo = new AppInfo(app, user, quietMode);
boolean isHideAppIcon = HideAppIconUtils.getInstall().isHidedApkPackageName(app.getComponentName().getPackageName());
if(isHideAppIcon){
continue;
}
iconRequestInfos.add(new IconRequestInfo<>(
appInfo, app, /* useLowResIcon= */ false));
mBgAllAppsList.add(
appInfo, app, !FeatureFlags.ENABLE_BULK_ALL_APPS_ICON_LOADING.get());
}
allActivityList.addAll(apps);
}
if (FeatureFlags.PROMISE_APPS_IN_ALL_APPS.get()) {
// get all active sessions and add them to the all apps list
for (PackageInstaller.SessionInfo info :
mSessionHelper.getAllVerifiedSessions()) {
AppInfo promiseAppInfo = mBgAllAppsList.addPromiseApp(
mApp.getContext(),
PackageInstallInfo.fromInstallingState(info),
!FeatureFlags.ENABLE_BULK_ALL_APPS_ICON_LOADING.get());
if (promiseAppInfo != null) {
iconRequestInfos.add(new IconRequestInfo<>(
promiseAppInfo,
/* launcherActivityInfo= */ null,
promiseAppInfo.usingLowResIcon()));
}
}
}
if (FeatureFlags.ENABLE_BULK_ALL_APPS_ICON_LOADING.get()) {
Trace.beginSection("LoadAllAppsIconsInBulk");
try {
mIconCache.getTitlesAndIconsInBulk(iconRequestInfos);
iconRequestInfos.forEach(iconRequestInfo ->
mBgAllAppsList.updateSectionName(iconRequestInfo.itemInfo));
} finally {
Trace.endSection();
}
}
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_ENABLED,
mUserManagerState.isAnyProfileQuietModeEnabled());
mBgAllAppsList.setFlags(FLAG_HAS_SHORTCUT_PERMISSION,
hasShortcutsPermission(mApp.getContext()));
mBgAllAppsList.setFlags(FLAG_QUIET_MODE_CHANGE_PERMISSION,
mApp.getContext().checkSelfPermission("android.permission.MODIFY_QUIET_MODE")
== PackageManager.PERMISSION_GRANTED);
mBgAllAppsList.getAndResetChangeFlag();
return allActivityList;
}
11.没修改的效果如下：
12.修改后的效果如下：
可以看到修改之后桌面很干净，没有哪些乱七八糟的应用图标，之前是一堆系统应用图标，给人焕然一新的感觉，而且还修改了排列的图标位置和列数等等，这些后面再讲解.
13.总结：
- 隐藏系统应用的Icon需要根据包名进行过滤
- 修改内容在LoaderTask类的loadAllApps()方法
- 隐藏webview和浏览器时可能会有多个包名
- 重复的内容封装一个工具类及使用
- AOSP系统定制化多样化，需要大家根据自己需求进行尝试
