How to check if the Flash players is installed on Android
Solution 1
Is there any special reason you need to check from Javascript and not from the Java code?
From Java code, you can do something like this:
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.adobe.flashplayer", "com.adobe.flashplayer.FlashExpandableFileChooser"));
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(intent, 0);
if (activities != null && activities.size() > 0) {
Toast.makeText(this, "Flash is installed!", Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(this, "Flash not installed!", Toast.LENGTH_LONG).show();
}
Works well on my HTC Desire.
If you're wondering where did I take the com.adobe.flashplayer.FlashExpandableFileChooser class name from, I simply took it from the Flash player's AndroidManifest.xml.
It looks like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
android:versionCode="101106016"
android:versionName="10.1.106.16"
package="com.adobe.flashplayer"
>
<application
android:label="Adobe Flash Player 10.1"
android:icon="@7F020000"
>
<activity
android:name="com.adobe.flashplayer.FlashExpandableFileChooser"
>
<intent-filter
>
<action
android:name="android.intent.action.MAIN"
>
</action>
<category
android:name="android.intent.category.DEFAULT"
>
</category>
<category
android:name="FlashExpandableFileChooser"
>
</category>
</intent-filter>
</activity>
<service
android:name="com.adobe.flashplayer.FlashPaintSurface"
>
<intent-filter
>
<action
android:name="android.webkit.PLUGIN"
>
</action>
</intent-filter>
<meta-data
android:name="type"
android:value="native"
>
</meta-data>
</service>
</application>
<uses-permission
android:name="android.webkit.permission.PLUGIN"
>
</uses-permission>
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="5"
android:maxSdkVersion="10"
>
</uses-sdk>
</manifest>
You can follow the instructions here on how to call this code from your JavaScript code. Specifically look at the setJavaScriptInterface method
To detect directly from JavaScript, use this snippet:
flashInstalled = false;
if (navigator.plugins && navigator.plugins.length) {
for (n = 0; n < navigator.plugins.length; n++) {
if (navigator.plugins[n].name.indexOf('Shockwave Flash') != -1) {
flashInstalled = true;
break;
}
}

You can use PackageManager:

Check out the getInstalledApplications() method.

how can I easily check in Javascript in the Android web browser if the Adobe Flash Player 10.1 (https://market.android.com/details?id=com.adobe.flashplayer) was downloaded from Android Market and installed?

Update: Thanks for replies, but I need the check code for Javascript, since I am doing the web based (HTML/Javascript/CSS) solution, not native Java application. Small part of the web application is done in Flex, so .swf file is displayed in
<div>
element, but prior of doing that I would like to check if Flash Player is installed or not. -
STeN about 13 yearsHi, thanks for reply, but I need Javascript code snippet, since I am doing the web application - see my answer below.

Lior about 13 yearsI added pure JavaScript code to the answer. It should work for any webKit based browser (And generally any netscape compatible browser).
