Create pref and move it to another location - Java for Android App Development

Sorry for the unclear title. What I'm trying to do is the following:
Code:
Button btncheat = (Button) findViewById(R.id.button1);
final EditText score = (EditText) findViewById(R.id.editText1);
btncheat.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String filename = "FlappyBird.xml";
String string = "<?xml version='1.0' encoding='utf-8' standalone='yes' ?>\n<map>\n<int name=\"score\" value=\"" + score.getText().toString() + "\" />\n</map>";
FileOutputStream outputStream;
try {
outputStream = openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
try {
String[] commands = {"mv /data/data/de.aciid.nullgc/files/FlappyBird.xml /data/data/com.dotgears.flappybird/shared_prefs/"};
RunAsRoot(commands);
} catch (Exception e) {
e.printStackTrace();
}
}
});
So, it creates the XML file from the String "string" (I don't know if I can do it like this, but the XML file looks right in the end) and move it to /data/data/com.dotgears.flappybird/shared_prefs/. The creation and moving of the XML file works flawless, but Flappy Bird does not read the pref properly. When I start the game, it says that my highscore is zero, although the score 999 (for example) is in the XML file. As I stated, the XML file looks right, I pasted an original and my modded XML in an online script and there are no differences whatsoever.
So why doesn't this work?

[Q] How to read directories?

Hey guys, this is the first time im trying my hand at android development, im still fairly new to development altogether.
Basically what I'm trying to do at the moment is read a list of folder-names in a particular directory, then write those to another file.
The file I'm writing to is at /data/data/com.rone/files/app_list
I'm trying to read from /data/data/
The app has been given su privileges as well. My issue is that I can't seem to read from any folder other than / (root)
Code:
private OnClickListener sort_listener = new OnClickListener() {
@Override
public void onClick(View v) {
String datafolders ="";
File dir = new File("/data/data/");
if(dir.isDirectory() && dir.canRead()){
Log.v("DEBUG", dir.getName() + " is the searching directory!");
for(int i = 0; i < dir.list().length; i++) {
datafolders += dir.list()[i] + " \n";
}
}
else {
Log.v("ERROR", "directory does not exist or can not be accessed!");
}
writeFile(datafolders, "app_list");
}
};
public void writeFile(String input, String filename) {
try {
FileOutputStream fos = openFileOutput(filename, Context.MODE_PRIVATE);
fos.write(input.getBytes());
fos.close();
return;
} catch (FileNotFoundException e) {
Log.v("ERROR", e.getMessage());
} catch (IOException e) {
Log.v("ERROR", e.getMessage());
}
}
public String readFile(String filename) {
try {
FileInputStream fis = openFileInput(filename);
String temp = "";
int ch;
while ((ch = fis.read()) > -1) {
temp += (char) ch;
}
fis.close();
return temp;
} catch (FileNotFoundException e) {
Log.v("ERROR", e.getMessage());
return "Exception" + e;
} catch (IOException e) {
Log.v("ERROR", e.getMessage());
return "Exception" + e;
}
}
It only writes to the file when I use:
Code:
File dir = new File("./");
Also, my app is specifically written for the SGS and I'm using Eclipse. Any way to get and import a custom SGS skin with the Menu and Back button functionality?
No replies? No one knows how to read the directories? Is there a limitation built-in that stops from reading directories? Even with su permissions?

[Q] Copy Image from Gallery Share (Send To) menu

Moderators... It says I am breaking the rules by asking a question and to ask in the Q&A... But the title of this is "Coding Discussion, Q&A, and Educational Resources" I am not breaking the rules intentionally, I just don't know where else to put this. This is a Coding Question, not a General Question that I would think would get buried and or lost in the General Q&A forum. Please move if you feel I am incorrect.
Hello All, I was hoping someone could help me.
I am trying to create an app that will hide pictures. I want to be able to Pick my App from the Share (Send To) menu from the Users Gallery and have it copy the file to a Directory I have created on my SDCard and then ultimately delete the file from the current location.
Here is what I have so far, but when I pick my app from the Share menu, it crashes the Gallery app. So... I can't even see any errors in my LogCat to even try and troubleshoot my issue.
Can someone point me to a working example of how to do this (I have searched the internet until I am blue in the face) or... I hate to say it... Fix my Code?
Any Help would be appreciated... Thanks!!

What's the gallery log output?
Btw, you're not breaking the rules. This is the right forum for Java Q&A.

How would I get the Logs for the Gallery? I am using and HTC ONE and it's the standard Gallery. Nothing shows up in LogCat so I'm stuck

Do you view the logs on your computer?
There should be an error message in the logs.

Which Logs?? As I said before. LogCat does not give any errors.

File Save code is not saving file in internal storage

i want to save a layout (relative layout), when i run the app everything is working fine, but i am unable to find saved file/s in the internal storage of the phone. Any help would be appreciated as i am new and unable to sort out what is going wrong . here is my code
Code:
public void saveMe(View v) {
// get prompts.xml view
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.prompt, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
context);
// set prompt.xml to alertdialog builder
alertDialogBuilder.setView(promptsView);
final EditText userInput = (EditText) promptsView
.findViewById(R.id.editTextDialog);
// set dialog message
alertDialogBuilder.setCancelable(false);
alertDialogBuilder.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
final String fileName = userInput.getText().toString();
final View view1=findViewById(R.id.relativeLayout); // The view that you want to save as an image
Bitmap bitmap = Bitmap.createBitmap(view1.getWidth(), view1.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(bitmap);
view1.draw(c);
if(fileName.length() == 0)
Toast.makeText(EidCardFinal.this,"Please Enter File Name",Toast.LENGTH_SHORT).show();
else{
File file = new File(context.getFilesDir(), fileName);
if (file.exists())
Toast.makeText(EidCardFinal.this,"File Already Exists",Toast.LENGTH_SHORT).show();
else{
try{
FileOutputStream out = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, out);
Toast.makeText(EidCardFinal.this,"File Saved",Toast.LENGTH_SHORT).show();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
}
});
alertDialogBuilder.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
// create alert dialog
AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
}
Try adding a line:
out.flush();
just before calling close() on the FileOutputStream. I think this will get the save code to work, and it's worth trying.

[Q] Google Drive android api - Downloading sqlite db file from drive

I am using the below code for downloading an already uploaded sqlite db file from google drive to the data/data/packagename/databases folder, but when the method completes, I am seeing a db corruption warning message logged in logcat and also all the data on the device for the app is overwritten and shows up blank, upon opening the app.
Code:
mfile = Drive.DriveApi.getFile(mGoogleApiClient, mResultsAdapter.getItem(0).getDriveId());
mfile.openContents(mGoogleApiClient, DriveFile.MODE_READ_ONLY, null).setResultCallback(contentsOpenedCallback);
--mfile is an instance of DriveFile
final private ResultCallback<ContentsResult> contentsOpenedCallback = new ResultCallback<ContentsResult>()
{
@Override
public void onResult(ContentsResult result)
{
if (!result.getStatus().isSuccess())
{
FileUtils.appendLog(getApplicationContext(), Tag + "-onResult", "Error opening file");
return;
}
try
{
if (GetFileFromDrive(result))
{
//FileUtils.Restore(getApplicationContext());
SharedPrefHelper.EditSharedPreference(getApplicationContext(), Constants.PREFS_DO_RESTORE, false);
}
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
};
private boolean GetFileFromDrive(ContentsResult result)
{
Contents contents = result.getContents();
//InputStreamReader rda = new InputStreamReader(contents.getInputStream());
BufferedReader reader = new BufferedReader(new InputStreamReader(contents.getInputStream()));
FileOutputStream outStream;
String currLine;
boolean restoreSuccess = false;
File sourceDbFile = BackupDBBeforeDeletion();
if(sourceDbFile != null)
sourceDbFile.delete();
try
{
outStream = new FileOutputStream(getApplicationContext().getDatabasePath(Constants.DB_NAME));
while ((currLine = reader.readLine()) != null)
{
outStream.write(currLine.getBytes());
}
outStream.flush();
reader.close();
outStream.close();
restoreSuccess = true;
}
catch (FileNotFoundException e)
{
// TODO: Log exception
}
catch (IOException e)
{
// TODO: Log Exception
}
return restoreSuccess;
}
When the method GetFileFromDrive completes, a db corruption shows up on LogCat and all the existing data on the app's datanase file (sqlite db) is gone.
Please help, as I have verified that the drive uploaded sqlite db file is correct and well formed, by downloading the same and opening it up in Sqlite Browser. It's the download from drive that is not working.
