本文介绍了如何检查是否安装了Flash？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我使用的这个片段，以检查是否安装了应用程序/活动：

i'm using this snippet to check if an app/activity is installed:

public static boolean isIntentAvailable(Context context, String action) { final PackageManager packageManager = context.getPackageManager(); final Intent intent = new Intent(action); List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); return list.size() > 0; } public static boolean isScanAvailable(Context context) { return isIntentAvailable(context, "com.google.zxing.client.android.SCAN"); }

在上面的例子中它检查是否安装的C扫描仪应用的酒吧$ C $，它工作得很好。不过，如果我尝试使用来检查的Adobe需要安装Flashplayer com.adobe.flashplayer 它不工作，并始终返回false。

In the above example it checks if the Barcode Scanner App is installed, which works just fine. However, if i try to check for the Adobe Flashplayer using com.adobe.flashplayer it doesn't work and always returns false.

有没有更好/更可靠的方法来检查闪光？

Is there a better / more reliable method to check for Flash?

推荐答案

嗯是的。我的code以上贴确实意图检查未工作的flash播放器（没有公开意图我猜的）。

Uhm yeah. My code posted above does Intent checking which isn't working for the flashplayer (no public intents i guess).

更明显的方式是只使用 getPackageInfo（）这工作得很好：

The more obvious way would be to just use getPackageInfo() which works just fine:

public static boolean isFlashAvailable(Context context) { String mVersion; try { mVersion = context.getPackageManager().getPackageInfo( "com.adobe.flashplayer", 0).versionName; Log.d("Flash", "Installed: " + mVersion); return true; } catch (NameNotFoundException e) { Log.d("Flash", "Not installed"); return false; } }
