Android :: Reasonable Size Of Data To Store In Bundle
Nov 24, 2009
My android app fetches a JSON structure from the net. It's somewhat large, maybe 2,000 characters in length. I need to store it away when my app gets killed so I can recover it quickly. I've tried saving it to an sqlite database, but that takes about 400ms, kind of long. I wonder if it's bad practice to just dump it into the save bundle:or are we really only supposed to be putting the smallest of items in bundles?

I currently have the Samsung Galaxy (I7500). I have it for a year+ now. A couple of months ago I wanted to buy the Desire, but I decided its too early for an upgrade (big mistake). It's very hard for me to keep waiting for the perfect device since I hate my galaxy so much. So my question is which phone would you recommend?
IPhone 4 no way ofcourse, Samsung Galaxy S no way cause Samsung really screwed things up with the original galaxy (and it has no Flash), which leaves me with HTC Desire HD or Desire Z. The DHD has an extremely weak battery, and I want my next phone to last a day (moderate user). So, is the Desire Z worth the money? The things that bother me with the Desire Z are:
1. Weight - It weigh 180 grams! Thats sick, way too much. (the Desire is about 135, which isn't light, but not heavy either)
2. Battery life - I'm not sure how long does it last under moderate usage.
3. Size - its quite big, and its especially because of the keyboard, which I don't really need / care about.So, Whats your opinion?

I'm trying to prevent the situation where an updated version of my app restores using a bundle written from a previous version of my app. In other words:
1) app v1 stops and calls onSaveInstanceState
2) app v1 saves the bundle
3) user goes to marketplace and updates the app to v2
4) user starts the v2 version of the app
5) v2 version calls onCreate passing the bundle with v1 data
Is that even possible? Do I need to worry about it?

I am adding some basic alarm functionality to my program via the use of AlarmManager and a BroadcastReceiver class (named AReceiver.java). My problem is that the data I add to the bundle attached to the Intent creating the PendingIntent appears to be lost. The only bundle data I can access in the AReceiver class is a android.intent.extra.ALARM_COUNT=1. Here is the basic code in the main activity class creating the Intent, PendingIntent and the AlarmManager: [Code in main activity - Notepadv3]
Intent intent = new Intent(Notepadv3.this, AReceiver.class);
intent.putExtra("teststring","hello, passed string in Extra");
PendingIntent alarmIntent = PendingIntent.getBroadcast(this, pendingPeriodIntentId, intent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, timeOfNextPeriod.getTimeInMillis(), alarmIntent);..................

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

I am building an app that can transfer a photo and bundle data to another persons phone that has the app.
The person would be close by, basically face to face.
In a perfect world I would like the process of file transfer to be less than 3 steps but I think that would be too much to ask for.
I am trying to figure out ways to do it but I keep coming up with blanks for every way I was thinking.
1. Bluetooth (Easier to code, more steps for the user)
2. NFC (How to implement and test)
3. Wifi Direct (Still has steps but less than Bluetooth, just learned about it today so I am new to it)
4. Connect to a Server (Make a server and connect devices)
5. HTTP (Make a temporary server on your phone?)

I have a notification that starts my activity and passes a messages using the intent's putExtra() function. The message is then displayed to the user in the activity's onCreate function. When the application is restarted due to a orientation change, the message is shown again as it is still in the intent's bundled data.
How can I remove the extra data?
I tried the following:
Bundle bundle = getIntent().getExtras();
if (bundle.getBoolean("showMessage")) {
// ... show message that is in bundle.getString("message")
// remove message
bundle.remove("showMessage");
}
But the message will still be shown after the orientation changed, seems like the intent used is not the one I changed, but the original one. The only workaround I found is to save the showMessage additionally in onSaveInstanceState(). Is there another way? Or is this the way to go?

I guess this question has been asked before, but I can't seem to find a proper answer/solution. Have a note-taking app, which allows to take pictures. For that I start an intent, that starts up the built-in camera-app. So far so good. But when I show that image in my app, it's in a much smaller format The funny/weird thing is, that the camera-app did take a full-resolution picture! But for some reason I can't get the full version to show in my app? So, when I use the standard Android Gallery app, and go to that picture, it is very obvious that it's full size (I can zoom in and see details I really can't see when I zoom in, in my own app). Also, the dimensions are really those of the original picture, taken with the 5MP camera. In my app, they are very small. My phone has Android 2.2, but the same happens on my emulator (Android 2.1). How should I retrieve the pictures in my app? Tried a couple of ways, but none works :( Don't need a complete example (allthough that's very welcome), just a few clues are enough to search for myself.

I am considering adding a means by which my app can perform functions over Google Voice, and the functionality would make little sense if I required the user to type in a password.I'd like a reasonable plan for storing the password locally and sending it (through google-voice-java) when demanded by Google Voice.Clearly, I'd like to properly represent the risks of the chosen scheme honestly to the user. I'd like the storage to be based atop writing it into a SharedPreferences created with flags.What form of obfuscation is suitable, and with what available salting ingredients and such should I customize it?

I'm writing an application that needs to store some small jpeg or pngs. Looking at the documentation i have seen that databases are stored under /data/data/package_name/databases I decided to store my data under /data/data/package_name/files. With the emulator i can see all these files (databases and images) under the proposed directories but moving the application on a real device and installing a file system browser i cannot see any file under /data. Can anyone explain me why? My application works perfectly on my mobile (HTC magic) so i think that data is downloaded and stored. If this is a security constraint,do i need to put the application under debug on the mobile in order to inspect file system?

TempMon is reporting 107 F + while streaming. That's battery temp, of course.CPU is significantly hotter than that.I've tried clocks from 700 up to 1100 and can't get it any cooler.at 700 its barely responsive enough to be functional.at 1200 it reboots.

For a particular activity - what is the best way to store data that needs to be displayed. The issue is that when the user changes orientation, you need to be able to re-render your activity which means you need to get back at that data that you use to render. I understand the MVC design pattern, but I guess I'm wondering where the M should be stored. Global variables? Static members of your activity? Serialized to private storage?

This issue has troubled me a lot, please help if you have any ideas.
- I am accessing an xml file from withing the apk, (stored in /res/ raw). The xml is read succesfully. My goal is to use this xml file as data that can be changed in the apk.
- I tried unpacking and packing the apk file with ZIP compression and the newly packed apk worked on the phone.
- I changed the xml file and packed the contents of the apk into a new apk
- "install was unsuccesful" was the result of installing the new apk
As I see it, for every file stored into the apk, there are equivalent references stored in the manifest and cert files:
for example: SHA1-Digest: YS8iSCii71WMNrK7CHy5XLXBo+k=
Do you have any other ideas of how I can store/alter information into the APK?

I'm looking for the best way to allow users to sync their data to their gmail account. The idea is to be able to access the same data via my other applications for computers, phones, etc... I need it to be a free service... The data is a list of items that contains a title tied to a playlist. Anyone know of a particular Google lab allowing such data? Or other cloud services?

I want to store location data in sqlite. A latitude coordinate is a double, with 15 point precision. As far as I can tell this corresponds with the 'REAL' datatype which is 8 bytes. The alternative I suppose would be to store it as a String, and simply convert it back into a double later. Does it make any odds which way I go? Are there differences in storage capacity / efficiency?

I'm getting hung up on how to handle the data for an app I'm designing. I want to pull a list of items from the net. The data is updated routinely, and I think it would be good to store all the data on the device so the app can load quickly and refresh the data in a background thread rather than have to wait for the network on every start-up.
I think I should make the data available in an XML and have a thread parse and save into a SQLite DB, but I'm not sure if that's the "best practice." Are there other ways that people go about handling this?

I am developing an Android application where you should be able to browse restaurants.
Im retrieving the information about the restaurants from a service, they are not stored locally on the device. But I want to allow the user to add a restaurant to his/her favorites.
What is the "best" way to store that kind of info on the device? Should I use Shared Preferences or Sqlite db? Or any other suggestions?

I want to store some additional data for each contact on Android.
I would have in mind creating my own database table for it, and then bind them to the real contact via a unique id.
I am wondering if Android has built in functionality to store additional data against contacts?
EDIT 2
Is there a defined field for birthday of the contact?
How do I store a date field?

I'm writing an application wherein users will sometimes make orders through it. I want to give users the option to save their billing info (name, address, etc.) so that it can be quickly restored later if they want to make another order. The user will enter a password to secure the data. Obviously I can't just put this as a file on the device, as anyone can root/find the data. Is there a built-in Android method for storing secure data that is locked with a password? If not, what is a good place to start for storing this data securely using Java?
