From d502404a44fb7c4ea739622d7f8bdd2a764d97a1 Mon Sep 17 00:00:00 2001 From: Dan Sandler Date: Thu, 9 Jan 2014 15:01:33 -0500 Subject: [PATCH] New launcher2 icon migration algorithm. The user will be able to request "icon migration", which is not a direct mapping of the old workspace, but rather follows this heuristic for bringing the user's favorite icons (by dint of their existence on the workspace) into Launcher3: Workspace shortcuts are placed in lexicographic order on the workspace starting at screen 0 (leaving the bottom row of screen 0 empty to make sure there's room to move things around). Folders are preserved and their contents sorted. Duplicate icons (that is, shortcuts with the same intent, pursuant to some cleanups) are removed. Hotseat icons are migrated in their original place, unless their new location is not accommodated by the hotseat (i.e. the L3 hotseat is too small on this device), in which case they're treated like any other shortcut and tossed into the workspace. To test, turn on Launcher.ENABLE_DEBUG_INTENTS and then: $ adb shell am broadcast -a com.android.launcher3.action.DELETE_DATABASE $ adb shell am broadcast -a com.android.launcher3.action.MIGRATE_DATABASE Bug: 12416411 Change-Id: Ia5c56f36c11455867ea20a39f70210f595020a87 --- AndroidManifest.xml | 1 + src/com/android/launcher3/Launcher.java | 20 ++ src/com/android/launcher3/LauncherModel.java | 32 ++- .../android/launcher3/LauncherProvider.java | 224 +++++++++++++++++- 4 files changed, 271 insertions(+), 6 deletions(-) diff --git a/AndroidManifest.xml b/AndroidManifest.xml index 4e27e6f27c..36fa4c190a 100644 --- a/AndroidManifest.xml +++ b/AndroidManifest.xml @@ -20,6 +20,7 @@ + 0) { + final int idIndex = c.getColumnIndexOrThrow(LauncherSettings.Favorites._ID); + final int intentIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.INTENT); + final int titleIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.TITLE); + final int iconTypeIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.ICON_TYPE); + final int iconIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.ICON); + final int iconPackageIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.ICON_PACKAGE); + final int iconResourceIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.ICON_RESOURCE); + final int containerIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.CONTAINER); + final int itemTypeIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.ITEM_TYPE); + final int screenIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.SCREEN); + final int cellXIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.CELLX); + final int cellYIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.CELLY); + final int uriIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.URI); + final int displayModeIndex + = c.getColumnIndexOrThrow(LauncherSettings.Favorites.DISPLAY_MODE); + + int i = 0; + int curX = 0; + int curY = 0; + + final LauncherAppState app = LauncherAppState.getInstance(); + final DeviceProfile grid = app.getDynamicGrid().getDeviceProfile(); + final int width = (int) grid.numColumns; + final int height = (int) grid.numRows; + final int hotseatWidth = (int) grid.numHotseatIcons; + + final HashSet seenIntents = new HashSet(c.getCount()); + + final ContentValues[] rows = new ContentValues[c.getCount()]; + + while (c.moveToNext()) { + final int itemType = c.getInt(itemTypeIndex); + if (itemType != Favorites.ITEM_TYPE_APPLICATION + && itemType != Favorites.ITEM_TYPE_SHORTCUT + && itemType != Favorites.ITEM_TYPE_FOLDER) { + continue; + } + + final int cellX = c.getInt(cellXIndex); + final int cellY = c.getInt(cellYIndex); + final int screen = c.getInt(screenIndex); + int container = c.getInt(containerIndex); + final String intentStr = c.getString(intentIndex); + Launcher.addDumpLog(TAG, "migrating \"" + + c.getString(titleIndex) + "\": " + intentStr, true); + + if (itemType != Favorites.ITEM_TYPE_FOLDER) { + if (TextUtils.isEmpty(intentStr)) { + // no intent?
