不多说，直接上代码
public static boolean isAppInstalled(Context context) { PackageManager pm; if ((pm = context.getApplicationContext().getPackageManager()) == null) { return false; } List packages = pm.getInstalledPackages(0); for (PackageInfo info : packages) { String name = info.packageName.toLowerCase(Locale.ENGLISH); if ("**.**.**".equals(name)) { //应用包名 eg:com.sina.weibo return true; } } return false; }
