My apk version code is version 3. with it I am using main expansion
file which was loaded with apk version code 1 (file name is similar to
main.1.ex.etc.eg.obb). The expansion file downloads fine on a device.
The expansion file has media file, so I using APEZProvider from the
Google Zip Expansion Library to play it with VideoView.
Calling VideoView.start() causes an Nullpointer exception.
What I have found so far: In APEZProvider.initIfNecessary() returns
Main expansion file version as 3 instead of 1. Thus trying to open
ZipResourceFile (mAPKExtensionFile) returns null.
APEZProvider.openAssetFile() causes null pinter exception as
mAPKExtensionFile is null.
Relevant code from APEZProvider class in Google Zip Expansion Library:
private boolean initIfNecessary() {
if ( !mInit ) {
Context ctx = getContext();
PackageManager pm = ctx.getPackageManager();
ProviderInfo pi = pm.resolveContentProvider(getAuthority(),
PackageManager.GET_META_DATA);
PackageInfo packInfo;
try {
packInfo = pm.getPackageInfo(ctx.getPackageName(), 0);
} catch (NameNotFoundException e1) {
e1.printStackTrace();
return false;
}
int patchFileVersion;
int mainFileVersion;
int appVersionCode = packInfo.versionCode;
if ( null != pi.metaData ) {
mainFileVersion = pi.metaData.getInt(mainVersion,
appVersionCode);
patchFileVersion = pi.metaData.getInt(patchVersion,
appVersionCode);
} else {
mainFileVersion = patchFileVersion = appVersionCode;
}
try {
mAPKExtensionFile =
APKExpansionSupport.getAPKExpansionZipFile(ctx, mainFileVersion,
patchFileVersion);
return true;
} catch (IOException e) {
e.printStackTrace();
}
}
return false;
}
@Override
public AssetFileDescriptor openAssetFile(Uri uri, String mode)
throws FileNotFoundException {
initIfNecessary();
String path = uri.getEncodedPath();
if ( path.startsWith(/) ) {
path = path.substring(1);
}
return mAPKExtensionFile.getAssetFileDescriptor(path);
}
I am not sure about this line of code in the above: ProviderInfo pi =
pm.resolveContentProvider(getAuthority(),
PackageManager.GET_META_DATA); Is this correct?
From Android reference for PackageManager.resolveContentProvider().
public abstract ProviderInfo resolveContentProvider (String name, int
flags)
Since: API Level 1 Find a single content provider by its base path
name. Parameters
name The name of the provider to find. flags Additional option flags.
Currently should always be 0.
Can someone confirm if i am doing something wrong or is it a bug.
