View 1 Replies View RelatedAndroid :: Way To Serialize A Bundle?
Apr 8, 2010I'd like to serialize a Bundle object, but can't seem to find a simple way of doing it. Using Parcel doesn't seem like an option, since I want to store the serialized data to file. Any ideas on ways to do this? The reason I want this is to save and restore the state of my activity, also when it's killed by the user. I already create a Bundle with the state I want to save in onSaveInstanceState. But android only keeps this Bundle when the activity is killed by the SYSTEM. When the user kills the activity, I need to store it myself. Hence I'd like to serialize and store it to file. Of course, if you have any other way of accomplishing the same thing, I'd be thankful for that too.

View 4 Replies View RelatedAndroid :: Communicating Between Receiver Class And An Activity Class
Jul 14, 2010I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

General :: Motorola Moto G - Save Apps And Games On Cloud To Save Storage?
Apr 19, 2014I have a Motorola Moto G 8GB which is running very low on storage (only about 800mb left). This phone does not take Micro SD cards but it comes with 50GB Google Drive storage. However i haven't used this at all. I am wondering whether i could download android apps and games to google drive, dropbox etc. Games like Real Racing take up about 1GB so i cannot download it to my phone. Can i download it to the Cloud? If this is not possible, is there any way that i could save the app data on the cloud. E.g. The Simpsons: Tapped Out is about 37mb to download off the play store, but then you must download the updates etc which are about another 250mb. is there anyway to save this 250mb on the cloud. Or any other games data.
