Where does application data file actually stored on android device?

I have developed an Android app using Appcelerator Titanium. This app will create a file in applicationDataDirectory and install a database as well.

If run on emulator, I can locate those files using "adb" command. But how about on Android device? Can I use the "My Files" app to view those file I created? (since I can see files created by other application there.)

Moreover, I expect once I removed the app on device, it will automatically remove the related files and database. Is that true?

Because I found that even I removed the app from the device, the database seems left behind. I can tell because after deleting app and re-run on device(from Titanium), it show previous data.

I am using Ti SDK 2.0.1GA2, Android Runtime V8. And using Samsung Galaxy Tab for testing. Thanks in advance.

This is a simple way to identify the application related storage paths of a particular app.

Steps:

  1. Have the android device connected to your mac or android emulator open
  2. Open the terminal
  3. adb shell
  4. find .

The "find ." command will list all the files with their paths in the terminal.

./apex/com.android.media.swcodec
./apex/com.android.media.swcodec/etc
./apex/com.android.media.swcodec/etc/init.rc
./apex/com.android.media.swcodec/etc/seccomp_policy
./apex/com.android.media.swcodec/etc/seccomp_policy/mediaswcodec.policy
./apex/com.android.media.swcodec/etc/ld.config.txt
./apex/com.android.media.swcodec/etc/media_codecs.xml
./apex/com.android.media.swcodec/apex_manifest.json
./apex/com.android.media.swcodec/lib
./apex/com.android.media.swcodec/lib/[email protected]
./apex/com.android.media.swcodec/lib/libcodec2_soft_common.so
./apex/com.android.media.swcodec/lib/[email protected]
./apex/com.android.media.swcodec/lib/libcodec2_soft_vorbisdec.so
./apex/com.android.media.swcodec/lib/libcodec2_soft_h263dec.so
./apex/com.android.media.swcodec/lib/libhidltransport.so
./apex/com.android.media.swcodec/lib/libcodec2_soft_h263enc.so
./apex/com.android.media.swcodec/lib/libcodec2_vndk.so
./apex/com.android.media.swcodec/lib/[email protected]
./apex/com.android.media.swcodec/lib/libmedia_codecserviceregistrant.so
./apex/com.android.media.swcodec/lib/libhidlbase.so
./apex/com.android.media.swcodec/lib/libcodec2_soft_aacdec.so
./apex/com.android.media.swcodec/lib/libcodec2_soft_vp9dec.so
.....

After this, just search for your app with the bundle identifier and you can use adb pull command to download the files to your local directory.

You can get if from your document_cache folder, subfolder (mine is 1946507). Once there, rename the "content" by adding .pdf to the end of the file, save, and open with any pdf reader.

Use Context.getDatabasePath(databasename). The context can be obtained from your application.

If you get previous data back it can be either a) the data was stored in an unconventional location and therefore not deleted with uninstall or b) Titanium backed up the data with the app (it can do that).

Application Private Data files are stored within <internal_storage>/data/data/<package>

Files being stored in the internal storage can be accessed with openFileOutput() and openFileInput()

When those files are created as MODE_PRIVATE it is not possible to see/access them within another application such as a FileManager.
