    copied!<p>My requirement is to open one app's Asset file from another app via content provider.(I am exposing that file with ContentProvider implementation)</p> <p>I am able to open few files and read, but while opening some files I am getting exception. Please find the implementation for opening Asset File.</p> <pre><code>@Override public AssetFileDescriptor openAssetFile(Uri uri, String mode) throws FileNotFoundException { AssetManager am = getContext().getAssets(); String file_name = uri.getLastPathSegment(); if(file_name == null) throw new FileNotFoundException(); AssetFileDescriptor afd = null; try { afd = am.openFd(file_name); } catch (IOException e) { e.printStackTrace(); } return afd;//super.openAssetFile(uri, mode); } </code></pre> <p>Some times, <code>am.openFd(file_name);</code> is throwing an exception saying that,</p> <pre><code>java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed at android.content.res.AssetManager.openAssetFd(Native Method) at android.content.res.AssetManager.openFd(AssetManager.java:329) at com.pineone.swfinstaller.SwfProvider.openAssetFile(SwfProvider.java:25) at android.content.ContentProvider$Transport.openAssetFile(ContentProvider.java:218) at android.content.ContentProviderNative.onTransact(ContentProviderNative.java:234) at android.os.Binder.execTransact(Binder.java:288) at dalvik.system.NativeStart.run(Native Method) </code></pre> <p>But, the same file I can open in my PC or even in Android device in some other manner.</p> <p>Can anyone point out me, in what scenarios, we will get this exception.</p> <p>Thanks in advance.</p>
