private String getInstalledAppListAsString(){ PackageManager pm = context.getPackageManager(); List<ApplicationInfo> apps = pm.getInstalledApplications(PackageManager.GET_GIDS); StringBuffer stringBuffer = new StringBuffer(); for (ApplicationInfo app : apps) { if (pm.getLaunchIntentForPackage(app.packageName) != null ) { // apps with launcher intent if ((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) == 1 ) { // updated system apps } else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) == 1 ) { // system apps } else { // user installed apps stringBuffer.append(app.packageName).append( ';' ); } } } return stringBuffer.toString(); } |
下面我们看看具体如何获取各个应用的相关信息呢
