I'm currently writing a phonebook-type application for the Android OS. I'm currently using a SQLiteDatabase to hold my contact information. I know that the database is held in
data/data/package-name/databases
However, I'd need root access to be able to find that directory on an Android phone. Is there a way to put the database somewhere I can find it without having to root the phone?
Just copy your DB to SD card programatically.
This code is an example how to access your DB =)
try {
input = new FileInputStream("/data/data/my_package_name/databases/" + DATABASE_NAME);
File dir = new File("/sdcard/database_dump");
dir.mkdir();
OutputStream output = new FileOutputStream("/sdcard/debugdump/myDb.db");
byte[] buffer = new byte[1024];
int length;
while ((length = input.read(buffer))>0) {
output.write(buffer, 0, length);
}
output.flush();
output.close();
input.close();
} catch (Exception e) {
e.printStackTrace();
}
After your DB is copied to the sd card you can take it and work with it on your PC using whatever SQLite editor you like. For example: http://www.softpedia.com/get/Internet/Servers/Database-Utils/SqlPro.shtml

I have a situation where i prompt user whether to backup their messages or no with the google backup service. I am successfully backing up the current realm database onto the SD card from where the backup to google service will happen.
But yet i though about the scenario where i want to actually restore the database from SD card to the current Realm Instance,meaning replace the current realm file with the one which is available on the SD Card.
In the older versions i saw that Realm gave a way to specify a custom path from which realm would read the database file,but in this new one i see none of it.
Any help please?
CREATE BACKUP FILE
public void backup() {
try {
// create a backup file
File exportRealmFile;
exportRealmFile = new File(EXPORT_REALM_PATH, EXPORT_REALM_FILE_NAME);
// if backup file already exists, delete it
exportRealmFile.delete();
// copy current realm to backup file
realm.writeCopyTo(exportRealmFile);
} catch (IOException e) {
e.printStackTrace();
}
realm.close();
}
RESTORE
private String copyBundledRealmFile(String oldFilePath, String outFileName) {
try {
File file = new File(activity.getApplicationContext().getFilesDir(), outFileName);
FileOutputStream outputStream = new FileOutputStream(file);
FileInputStream inputStream = new FileInputStream(new File(oldFilePath));
byte[] buf = new byte[1024];
int bytesRead;
while ((bytesRead = inputStream.read(buf)) > 0) {
outputStream.write(buf, 0, bytesRead);
}
outputStream.close();
return file.getAbsolutePath();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
Hope this help.

I'm doing an application with alot of data in the database so I need to make an external database with SQlite browser and put it in my application
my problem is
I can't see data/data/database because my mobile isn't rooted and I can't root it for reasons
I'm using BlueStack emulator in Eclipse IDE
Please help
Thank you
you can create your database and put it in your assets directory
and on first use copy to data directory.
try {
String destPath = "/data/data/" + getPackageName()
+ "/databases/YOURDbFileName";
File f = new File(destPath);
if(!f.exists()){
Log.v(TAG,"File Not Exist");
InputStream in = getAssets().open("YOURDbFileName");
OutputStream out = new FileOutputStream(destPath);
byte[] buffer = new byte[1024];
int length;
while ((length = in.read(buffer)) > 0) {
out.write(buffer, 0, length);
}
in.close();
out.close();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
Log.v("TAG","ioexeption");
e.printStackTrace();
}
You need to copy the external database into a folder that is accessible by the phone. So that you can manipulate the database from there.
new location must be: "/data/data/your.app.package/databases/yourdatabasename"
I wrote an app which logged data and saved it via SQL into a .db File. I had a method copying it from internal memory to SD card.
Now i wrote a second app, which needs to work with this particular .db file. As i think, that apps can't get access to package files from other apps
(in this case
/data/data/app1_package/databases/my_database.db
)
i need somehow to work with my DB on the SD Card. How do i do that?
Can i use this path in my SQLiteHelper class? Should i copy it from SD to my package, is that even possible (access rights etc.)?
I'm a beginner in databases, some help would be nice.
You can open any readable file path as a database:
File dbFile = new File( Environment.getExternalStorageDirectory(), "myfile.db" );
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbFile,null,null);
Note: check if sd-card is mounted before using this code.
yes place the DB file in your assets folder and get it this way :
DB_PATH="/data/data/app1_package/databases/my_database.db"
in your create :
is = getAssets().open("Meaniningss.db");
write(is);
the method :
public void write(InputStream is) {
try {
OutputStream out = new FileOutputStream(new File(DB_PATH));
int read = 0;
byte[] bytes = new byte[1024];
while ((read = is.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
is.close();
out.flush();
out.close();
System.err.println(out + "\n");
} catch (IOException e) {
e.printStackTrace();
}
}
I am developing an android app. I have tested the app in mobile and now i need to see the database of my app(i.e mobile database). I am using Mac and confused how to pull the database from the mobile and see it in SQLite browser.
Thanks for your help guys.
You won't be able to on a real device (unless it is rooted). The data directories are protected against access by anything other than the owning app.
To get it off of the device you need to set up a method in your app to copy the database to somewhere that is accessible (like an SD card). Following is code I've used to do that before:
public void backup() {
try {
File sdcard = Environment.getExternalStorageDirectory();
File outputFile = new File(sdcard,
"yourDB.bak");
if (!outputFile.exists())
outputFile.createNewFile();
File data = Environment.getDataDirectory();
File inputFile = new File(data,
"data/your.package.name/databases/yourDB");
InputStream input = new FileInputStream(inputFile);
OutputStream output = new FileOutputStream(outputFile);
byte[] buffer = new byte[1024];
int length;
while ((length = input.read(buffer)) > 0) {
output.write(buffer, 0, length);
}
output.flush();
output.close();
input.close();
} catch (IOException e) {
e.printStackTrace();
throw new Error("Copying Failed");
}
}
I have an SQLite database in my application. When I go to check if the database is created or not in File Explorer, there is no any database file within the data folder. It didn't even show up using the adb shell command. Does this mean that the database hasn't been created yet? Any suggestions on how to solve this?
If you are using an actual device, you will not be able to see or access it from outside unless you root your phone.
If you are using the emulator, the DDMS view will let you navigate to it and pull it from there.
Or, you could have an issue with creating your DB. Without seeing your code we cannot tell.
EDIT
If you want to get the file off of a real device, you'll need to implement a method to copy it from your data directory to someplace where you do have access (such as your SD card). This would do the trick:
public void backup() {
try {
File sdcard = Environment.getExternalStorageDirectory();
File outputFile = new File(sdcard,
"YourDB.bak");
if (!outputFile.exists())
outputFile.createNewFile();
File data = Environment.getDataDirectory();
File inputFile = new File(data, "data/your.package.name/databases/yourDB");
InputStream input = new FileInputStream(inputFile);
OutputStream output = new FileOutputStream(outputFile);
byte[] buffer = new byte[1024];
int length;
while ((length = input.read(buffer)) > 0) {
output.write(buffer, 0, length);
}
output.flush();
output.close();
input.close();
} catch (IOException e) {
e.printStackTrace();
throw new Error("Copying Failed");
}
}
