Android:获取包括系统应用程序在内的所有已安装应用程序列表的问题
Android:获取包括系统应用程序在内的所有已安装应用程序列表的问题
提问于 2016-07-14 13:23:08
我有一个listview显示所有安装的应用程序，包括一些系统应用程序，但不显示画廊，联系人，消息应用程序。请告诉我如何获得所有这些系统应用程序。以下是我的代码
public static List getInstalledApplication(Context c)
{
// return c.getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA);
List<ApplicationInfo> installedApps = new ArrayList<ApplicationInfo>();
PackageManager pm = c.getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(0);
for(ApplicationInfo app : apps) {
//checks for flags; if flagged, check if updated system app
if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) == 1) {
installedApps.add(app);
//it's a system app, not interested
} else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) == 1) {
//Discard this one
//in this case, it should be a user-installed app
// installedApps.add(app);
} else {
installedApps.add(app);
}
}
return installedApps;
}告诉我我哪里弄错了。帮我写一些代码。

试试这段代码
final PackageManager pm = getPackageManager();
//get a list of installed apps.
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo packageInfo : packages) {
Log.d(TAG, "Installed package :" + packageInfo.packageName);
Log.d(TAG, "Source dir : " + packageInfo.sourceDir);
Log.d(TAG, "Launch Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName));
}
// the getLaunchIntentForPackage returns an intent that you can use with startActivity()编辑1个
PackageManager pm = getPackageManager();
Intent i = new Intent(Intent.ACTION_MAIN);
i.addCategory(Intent.CATEGORY_HOME);
List<ResolveInfo> lst = pm.queryIntentActivities(i, 0);
for (ResolveInfo resolveInfo : lst) {
Log.d("Test", "New Launcher Found: " + resolveInfo.activityInfo.packageName);
}这可能会对你有帮助
