Where does application data file actually stored on android device

Question

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:

Have the android device connected to your mac or android emulator open
Open the terminal
adb shell
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.
