Android :: Attaching Txt File While Email From Internal Package File Storage
Jun 8, 2010
I am successful in creating file using openFileOutput(). and can read the file using openFileInput().
I am able attach file from external storage sdcard while emailing the same using getExternalStorageDirectory as sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+Environment.getExternalStorageDirectory()+"/ zibra.txt"));
But while trying to attach file from the openOutputFile stored area using sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+ getFilesDir() + "/zibra.txt"));, resulting emptied file emailing.
My file is stored in "/data/data/com.example/files/zibra.txt".
what is going wrong in it?
CODE:...................

I'm writing a simple budget app for myself, and I'm having trouble figuring out how to write to internal storage. I don't seem to be writing to the file properly and I can't find any more in depth examples than the Data Storage article on developer.android.com. Basically, I'm trying to write a test float to the MyBalance file, then read it into balance. In my actual code I use try/catch statements around the file in/out operations but I skipped them to make the code more readable.
float test = 55; float balance; byte[] buffer = null;
FileOutputStream fos = openFileOutput( "MyBalance", Context.MODE_PRIVATE );
fos.write(Float.floatToRawIntBits(balance));
fis.read(buffer); //null pointer
ByteBuffer b = ByteBuffer.wrap(buffer);
balance=b.getFloat();
That's the gist of it, anyone see what I'm doing wrong? I went ahead and converted to/from String but I still don't think the file is being created. I have an if statement that reads from it if it exists in onResume() and it isn't being run. Lemme post some of my code. Here's how I'm writing the file, (setbal is an EditText and balanceview is a TextView):
balance = Float.valueOf(setbal.getText().toString());
balanceview.setText(setbal.getText());
balstring = String.valueOf(balance);
for (int i = 0; i < balstring.length(); ++i)
try { fos.write((byte)balstring.charAt(i));
} catch (IOException e) { e.printStackTrace();
}
I check if the file exists in onResume() like so:
File file = new File("data/data/com.v1nsai.mibudget/balance.txt");
Is that where an internal file for that context would be stored?

I am writing a app that reads a file from the internal storage on startup. I have followed the guildelines here:
http://developer.android.com/guide/topics/data/data-storage.html#file...
It successfully works on the emulator, and I can find the file my app created under
DDMS > data > data > com.MyAppName > files.
Now I would like to install my app on a real device, but do I need to explicitly copy the file onto the device? If so, what's the location should I copy the file to? Or will the file be created when I install my app? I need some pointers or guidelines, I'm quite clueless about the device. Or perhaps if anyone knows any keywords for me to search for an answer.

I am writing a code for an android app in which I have to captures image and save it into internal storage of android. For this I have written the following code-
Code:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
String newPath = PATH+"/"+folderName+"/"+imageName+".jpg";
File file = new File( newPath );
file.mkdirs();
[Code]...
This code creates jpeg file but don't write the image into it.
Later I tried writing following code in onActivityResult-
Code:
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
Bitmap bitmap = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0, bos);
byte[] bitmapdata = bos.toByteArray();
[Code]...
But its still not working.

I dnt know what Ive done last night But all the files in my internal storage are disappeared. I mean the image file. So any way to find the file out? My device is a Sony Xperia SP , which is rooted but with locked BL. there are too many important and valuable photos there.
Never ask me to use MSC mode instead of MTP, as my photos are save in internal memory Undelete and Remote for Android are tried but useless

We are suddenly unable to install our app on G1 developer phones with 1.6. Works perfectly on emulator. When installing the app we get:
Installation error: INSTALL_FAILED_INSUFFICIENT_STORAGE Please check logcat output for more details. Launch canceled!
And logcat:
PackageManage: Couldn't copy package file to temp file.
What does this mean? We checked that there is actually room enough on the phone.. We tried reverting the code to a revision that worked previously, but are getting the same error.

I accidentally deleted the AndroidManifest.xml from the Package Explorer panel. The file still exists intact in the original directory but I cant find any option in the Eclipse ide that seems to be for restoring it. I thought it might be 'Import' but manifest isnt one of the types on offer. Can anyone suggest how I can get the file into the package?

1) How the heck do I send a file? I can't attach a file in g-mail or MMS that isn't a picture. Weird that this is an issue.
2) I have people in my phone book named different then they are named in face book so I have double entries (i.e. John - Johnny). I know I can merge contacts in Google contacts on line but I don't see my face book buddies on there.

I know a variant of this question was asked before trying-to-attach-a-file-from-sd-card-to-email But the solution offered, i.e. a reboot doesn't seem to do it for me. I have seen a good number of group postings which support this being a problem. I can only assume the OP for the linked to question made some other changes, possibly to the manifest which allowed his code to work.
The behaviour I am seeing is the Email intent handling the attachment of the jpeg from the sdcard but dealing with it as a 0 length file which is discarded when sent. I have tried setType as jpeg/image and image/jpeg as I have seen it expressed both ways....................

I am trying to put an XML file containing over 1,000 different fish into my app so that I can read this file, create an Array and attach that to the AutoCompleteTextView. I first tried to create a string-array in a resource file but apparently the array was to large and would never actually load anything after a certain number of values. So want I want to do is add that XML file to a place in my app that I can access it and read from it. Whenever I try to bring the XML file in I get all these errors in Eclipse. So how do I add this file and how do I reference it later in order to access it? I could just store it online and access it that way but I think it is a little bit of a waste to have to access the net for that if I can instead just add it to my package setup someplace.

If i have a apk file and want to know the package name and class hierarchy, how do i do it?
Suppose I have some sample APK file named "SampApp.apk" which contains classes inside "com.android.sampApp".
Is there any tool in Android SDK which shows the package name when APK file is passed as a parameter.
As the Class files are compressed to dex file I am not able to check the actual package name.

I'm am creating an Android application, but in order to have one of the functionalities working I need to read a predefined xml file whilst only knowing its name, not the R.id..
In normal Java I know I can use
getClass().getClassLoader().getResource(xmlName)
But using the limited Android SDK thats not working, any knows how to solve this?

I need to save these configurations into a file, and in my app I could change these configurations. In other words, I need a file to take all my config data, and in my app, I could read/write this file as I want.
I've searched document and mailing list archive, and have not found the exact solution. 1. SharedPreferences could not solve : It could only do with simple key/value pairs, my configuration data is more complex . 2. file in /assets , /res/raw could not solve: It seems that the file in these position would be read only
I've found a way, it almost solved my problem, but still not. Our code could deal with the file in /data/data/package-name/files on the target file system, this is good to me, but how could I put my file in this directory after my app has been installed? My app need to read these configurations when it starts.
My question is how could I pack my data file into my apk package, and then my app could read/write this file when it is run.

This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)?
This binary format is not discussed in the in the documentation here: http://developer.android.com/guide/topics/manifest/manifest-intro.html
I want to access this information from outside the Android environment, preferably from Java.

I have some problem installing my apk file in code. Wondering if anyone could find out what I did wrong.
What I was trying to do is put a Check Upgrade function in our program. When user clicks it, it will send request to our web server and find out what is the latest version. I use app versionName to stamp a version, something like 2010.11.23. I don't use the version code in Manifest.xml file. So our program sees the latest VersionName is later than itself, it will download the latest one, and then use the following code to install the new apk file:
CODE:........
Now looks like, everytime when I changed the VersionName, it will fail to install the apk file. It downloads the file fine. I don't know exactly why. Sometimes, in Eclips, when I hit debug, I got error saying "Re-installation failed due to different application signatures". I don't know if this is the same error caused the installation failed.
So, looks like my questions are:
Should that upgrade logic work? I am wondering if it has something to do with the VersoinName.
What could cause the application signature change? (I did sign our program before I put it on our server, but I always use the same key file for different versionName. )

I published my app on the market, and when I first tried installing it from there, I got the 'package file was not signed correctly' error. Uninstalling the unsigned version I was testing with let me install from the market with no problems. However, from the comments, it looks like no one else can install my application.
I've put other versions up that worked, and I used the same certificate, so I'm pretty sure it is not an issue with the validity days for the certificate.
The name of my application is Bloxors. It will be going up and down as I try to figure out what the issue is here, but if someone else who is getting the error can debug it it would be greatly appreciated.

I recently uploaded my application to the android market however it's refusing to run when downloaded due to the error
Package file was not signed correctly
I first published the packet using eclipse, right click export, creating a keystore then publishing, however it refuses to work.
I then downloaded the keytool and jarsigner and used them to sign an upgrade which I posted instead. However this gives the same error.
And since I cannot delete the application I cannot try and start again,

I'm the developer of a French Android Application about handball french competitions, Hand Score.
Since my last update I've just published, many of my users are not able to download the update, or even reinstall the application. They got this message : "Package file is invalid"
But for unknown reasons, other users aren't faced with this problem. SO I really don't understand what is the origin of my problem and how can i solve it !
I ask some of my users to clean cache and clear data of Google Play application, but it didn't resolve it. So I am in a dead end...

General question for those in the "know". I'm trying to free up some space on my SD card (before I upgrade to a 32GB) and I was wondering---for apk's downloaded outside of the market..once you install that apk, can u delete the apk package file off your SD? Or will this cause problems to the overall application itself?
