在Android中的WebView播放本地视频 [英] Playing local video in WebView on Android
问题描述
我要建一个的WebView的应用程序
多数民众赞成应该播放视频,这是保存在本地。奇怪的是视频播放器不工作与本地的视频文件。它播放视频保存在服务器上,但。
I'm building an app with a WebView
thats supposed to play a video, that's saved locally. Strangely the video player is not working with local video files. It does play videos saved on a server though.
本地文件(html和视频)保存在文件夹中资产/ html_test
The local files (html and video) are saved in a folder assets/html_test
下面是文件。
HTML
<div class="video-container">
<p>Server</p>
<video poster="video/star.png" controls>
<source src="http://broken-links.com/tests/media/BigBuck.m4v" />
</video>
</div>
<div class="video-container">
<p>local</p>
<video poster="video/star.png" controls>
<source src="BigBuck.m4v" />
</video>
</div>
的onCreate在活动
WebView browser = (WebView) findViewById(R.id.browser);
WebSettings webSettings = browser.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setPluginState(WebSettings.PluginState.ON_DEMAND);
webSettings.setAllowFileAccessFromFileURLs(true);
browser.setWebChromeClient(new WebChromeClient());
browser.loadUrl("file:///android_asset/html_test/video.html");
第一视频作品,第二个没有。我尝试了不同的值的源
,他们都没有为我工作:
The first video works, the second one doesn't. I tried different values for the source
, neither of them worked for me:
<source src="BigBuck.m4v" />
<source src="file:///android_asset/html_test/BigBuck.m4v" />
不知道这是否是相关的,但只要我preSS发挥,的logcat
拿出这样的:
01-07 12:19:18.073: E/MediaPlayer(32542): error (1, -2147483648)
01-07 12:19:18.073: E/MediaPlayer(32542): Error (1,-2147483648)

本质上,它是一个权限问题。 这是他张贴的链接。与 MODE_WORLD_READABLE
复制文件建议的方法是pcated德$ P $,请使用下面的链接中描述的方法,并保存在外部存储器中的文件
Essentially it's a permission problem. Here is the link he posted. The suggested method for copying files with MODE_WORLD_READABLE
is deprecated, use the method described in the link below and save the files in the external storage
我不得不将文件复制到外部存储和访问视频文件存在。自的路径外部存储是几个版本机器人中的不同,我复制所有相关的HTML文件(包括所有的JS,图形和视频文件)。请参阅<一href="http://stackoverflow.com/questions/4447477/android-how-to-copy-files-in-assets-to-sdcard">copying文件,向下滚动的解答,如果您有子文件夹。
I had to copy the files to the external storage, and access the video file there. Since the path to the external storage is different within the several versions of android, I copied the all relevant HTML files (including all JS, graphics and video files). See copying files, scroll down for the answer if you have sub folders.
下面是我的复制方法:
private void copyAssets(String path)
{
String[] files = null;
try
{
files = getAssets().list(path);
} catch (IOException e)
{
e.printStackTrace();
}
if (files.length == 0)
copyFile(path);
else
{
File dir = new File(getExternalFilesDir(null), path);
if (!dir.exists())
dir.mkdir();
for (int i = 0; i < files.length; i++)
{
copyAssets(path + "/" + files[i]);
}
}
}
private void copyFile(String filename)
{
InputStream in = null;
File file;
OutputStream out = null;
try
{
in = getAssets().open(filename);
} catch (IOException e)
{
Log.e(TAG, "ERROR WITH in = getAssets().open: " + filename);
e.printStackTrace();
}
file = new File(getExternalFilesDir(null), filename);
try
{
out = new FileOutputStream(file);
} catch (FileNotFoundException e)
{
Log.e(TAG, "ERROR WITH out = new FileOutputStream(file);");
e.printStackTrace();
}
byte[] data;
try
{
data = new byte[in.available()];
in.read(data);
out.write(data);
in.close();
out.close();
} catch (IOException e1)
{
e1.printStackTrace();
}
}
在我的的onCreate
我称之为
copyAssets("matrix");
与基体是在我的资产的文件夹,多数民众赞成持有的所有文件和子文件夹。
with matrix being the folder in my assets thats holding all files and sub folders.
