... ParseInstallation.getCurrentInstallation () saveInBackground (); does not work
I have created an app on iOS that uses Parse to store data and also uses Parse Push to exchange messages between users. Now I am converting my app to Android and am trying to use the same Parse component for both. I am uploading / downloading data successfully and I can even send a message from an Android user to an iOS user, but I cannot get my Android device to receive messages. The underscore issue is that I can't get the installation to work. I am calling this block of code from my onCreate function:
Parse.enableLocalDatastore(this);
Parse.initialize(this, "id1", "id2");
ParsePush.subscribeInBackground("", new SaveCallback() {
@Override
public void done(ParseException e) {
if (e == null) {
Log.d("com.parse.push", "successfully subscribed to the broadcast channel.");
} else {
Log.e("com.parse.push", "failed to subscribe for push", e);
}
}
});
ParseInstallation.getCurrentInstallation().saveInBackground();
After calling this code, I check the new installation in the database, but nothing appears. Seems to do ParseInstallation.getCurrentInstallation().saveInBackground();
nothing. Did I miss something?

the object associated with the installation on a given device does not have a row in the parsing installation table, so you get an error, there are 2 possible solutions to this problem:
- uninstalling the application and reinstalling it (which is not an acceptable solution), or
- manually clearing the application session analysis cache. see the answer on how to do that what
This method must be called before calling Parse.initialize ...
public static boolean deleteInstallationCache(Context context) {
boolean deletedParseFolder = false;
File cacheDir = context.getCacheDir();
File parseApp = new File(cacheDir.getParent(),"app_Parse");
File installationId = new File(parseApp,"installationId");
File currentInstallation = new File(parseApp,"currentInstallation");
if(installationId.exists()) {
deletedParseFolder = deletedParseFolder || installationId.delete();
}
if(currentInstallation.exists()) {
deletedParseFolder = deletedParseFolder && currentInstallation.delete();
}
return deletedParseFolder;
}

Alternatively you can use the private-private ParseInstallation.clearCurrentInstallationFromDisk method (context context)
public static void clearParseInstallation(Context context) {
try {
Method method = ParseInstallation.class.getDeclaredMethod("clearCurrentInstallationFromDisk", Context.class);
method.setAccessible(true);
method.invoke(null, context);
} catch (Exception e) {
Log.e(e);
}
}
