Question

的AndroidManifest.xml： <provider android:authorities="com.mygame.expansion" android:exported="false" android:multiprocess="true" android:name="org.apache.cordova.xapkreader.XAPKProvider" />

我有一个APEZProvider类，来自Android SDK / extras文件夹。它扩展了ContentProvider。

我还有一个XAPKProvider类，它扩展了APEZProvider：

public class XAPKProvider extends APEZProvider {
 @Override public String getAuthority () {return "com.mygame.expansion";}

 public int mainFileVersion  = 0;
 public int patchFileVersion = 0;

 @Override public boolean initIfNecessary () {
  if (mInit) return true;
  Context ctx = getContext ();
  try {
   mAPKExtensionFile = APKExpansionSupport.getAPKExpansionZipFile (ctx, mainFileVersion, patchFileVersion);
   mInit = true;
   return true;
  } catch (IOException e) {
   e.printStackTrace ();
  }
  return false;
 }
}

如何访问AndroidManifest.xml文件中创建的ContentProvider对象，以便我可以修改mainFileVersion和patchFileVersion变量？

我发现另一个StackOverflow post让我得到答案。我需要覆盖＆＃34;呼叫＆＃34;。例如：

ContentResolver cr = cordova.getActivity().getApplicationContext().getContentResolver();
String expansionAuthority = bundle.getString("expansion_authority", "");
cr.call (Uri.parse("content://" + expansionAuthority), "set_expansion_file_versions", null, bundle);

然后：..

@Override public Bundle call (String method, String arg, Bundle bundle) {
 if (method.equals("set_expansion_file_versions")) {
  mainFileVersion  = bundle.getInt("main_version" , 1);
  patchFileVersion = bundle.getInt("patch_version", 1);
  expansionAuthority = bundle.getString("expansion_authority", "com.sample.expansion");
  xmlDataReceived = true;
  return null;
 }
 return null;
}
