download picture from dropbox and watch it in one activity in android

I have 3 activities in my Android app. The first one opens an ssh connection and on my raspberry pi it does different kind of things (running python scripts, uploading stuff to dropbox etc). This process generally takes 15-20 seconds and when it is ready, the second activity comes up where i click a button that downloads the files, and then, on the third activity i can see the files that my rpi made.
I want to make the the last two activity into one, so the user does not have to click anything to download his or her file. Which is the easiest way? Can I solve this with delays or threads or only the asynctask remains?
The file gets downloaded earlier in the same activity as this placePic function and then I call it:

How to clear User data and cache files for all installed applications programmatically in android

I'm doing an Android application which needs to list out all installed applications with cache size & app user data size. Now I want to clear the data (both cache & User data) of all installed applications. Below is my tried code.
Its not clearing data. When I go to Settings -> Applications -> Manage Applications -> Your Application -> Size is still showing as data & Cache. How could I remove those unused data for all installed applications. Thanks.
My code:
...
public static void trimCache(Context context) {
try {
File dir = context.getCacheDir();

deleteDir(new File(appDir, s));

Use
listView.invalidate();
after you have made changes to the list
Eg. you have added/removed/updated data in listView.

Just an idea:
Call your code public CategoryListAdapter1 adapter; as global to class.
Use adapter.notifyDataSetChanged(); whenever your list going to refresh.

Notify when download finish dropbox Core API

I'm making a module that can download all file from apps folder on dropbox to devices.
Now, I'm using Core API to download a file. Everything works fine. But with multiple file, I don't know when the current file finish download to go to the next file.
Here is my download code:
final String cachePath = FileHandler.ROOT_LOCAL_FOLDER_DIR + "/" + mFile.getFileName();
try {
mFos = new FileOutputStream(cachePath);
} catch (FileNotFoundException e) {
mErrorMsg = "Couldn't create a local file to store the image";
return false;
}
ProgressListener mProgressLisenter = new ProgressListener() {
#Override
public void onProgress(long arg0, long arg1) {
// TODO Auto-generated method stub
tmpFile = new File(cachePath);
OnDownloadProgressDropboxChecked(FileHandler.PROGRESS_STATUS_ONPROGRESS, (int) (arg0 * 100 / arg1));
}
#Override
public long progressInterval() {
return 100;
}
};
mDownloaded = mApi.getFile(mFile.getFileId(), null, mFos, mProgressLisenter);
OnDownloadDropboxChecked(TRUE, "Download complete");
} catch (DropboxUnlinkedException e) {
mErrorMsg = "Unlinked";
} catch (DropboxPartialFileException e) {
// We canceled the operation
mErrorMsg = "Download canceled";
} catch (DropboxServerException e) {
}
}
I've tried:
Catch progress download, when reached 100% then notify - On this way, the OnProgress of dropbox isn't show up imediately and sometime It not reach 100%
Put It in a asynctask - Useless
I'm out of idea now, any advance are good for me.
Edited:
the solution is put some trigger under getFile() then It work.
here is my complete class:

public interface OnAsyncDownloadProgressListener {
public abstract void OnAsyncDownloadProgress(int status, int percent);

The error caused by 'OnDownloadDropboxChecked()' of Asynctask fired before the one of getFile(). So It return a false notify.

Converting my comment to an answer:
If I'm reading this right, you're using the Android Core API SDK, right? If so, I think that when mApi.getFile returns, the file has been downloaded. So you can do whatever you need to do on the next line.

Updating the profile picture of a user

I am making an application where I am using ImageLoading Framework for downloading the images from the server and put the URLs in the cache. Now I want the user's profile picture updating but even after updation of the profile pic on the sever it's not displaying in the application.
The app is showing the old profile pic of the User. Why this problem is arising and how can I troubleshoot?
Code for update onclick:
update_profile_pic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
String value_for_test="delete";
Toast.makeText(getBaseContext(), "it works", Toast.LENGTH_SHORT).show();
Intent i=new Intent(getApplicationContext(),ProfilePictureCaptureHomeActivity.class);
i.putExtra("image",value_for_test);
startActivity(i);
Profile Pic CaptureHome
DBAdapter db = new DBAdapter(getApplicationContext());
db.open();
if (null == phoneNumber)
{
Cursor c = db.getUserInfo();
phoneNumber = c.getString(0);
imageUrl = c.getString(1);
System.out.println("the imageUrl is"+imageUrl);
c.close();
}
setContentView(R.layout.profilepic_capture);
if (null == imageUrl)
{
Cursor imageUrlObj = db.getUserInfo();
imageUrl = imageUrlObj.getString(1);
System.out.println("the imageurl is"+imageUrl);
imageUrlObj.close();
}
db.close();
for updating the profile picture:
if(image!=null){
Toast.makeText(getApplicationContext(), "Redirected", Toast.LENGTH_LONG).show();
imageUrl=null;
}
if(imageUrl != null)
{
Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ListeningAndSharingHomeActivity.class);
uploadimg.putExtra("phoneNumber", phoneNumber);
startActivity(uploadimg);
}
else
{
Log.v("ProfilePictureCaptureHomeActivity", "Staying Here");
}
_gallerybutton = (ImageButton) findViewById(R.id.btn_gallery);
_photobutton = (ImageButton) findViewById(R.id.btn_photo);
System.out.println("here in popup phoneeeeee" + phoneNumber);
System.out.println("here in flag************" + firstUpload);
_gallerybutton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
System.out.println("here in galleryyyyyyyyyy");
Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromGallery.class);
uploadimg.putExtra("phoneNumber", phoneNumber);
startActivity(uploadimg);
}
});
_photobutton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
System.out.println("here in take piccccc");
Intent capIntent = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromCamera.class);
startActivity(capIntent);
}
});

have a look at this code.
private String deleteExistingFile(String url , Context context)
{
String SaveFolderName = context.getFilesDir().getAbsolutePath() + "/yourinternalmemoryfolder";
String str_randomnumber= url.substring(url.lastIndexOf("/") + 1);
File wallpaperDirectory = new File(SaveFolderName);
if (!wallpaperDirectory.exists())
wallpaperDirectory.mkdirs();
String Photo_ImagePath=SaveFolderName+"/" + str_randomnumber ;
String result = "";
System.out.println("file path to be deleted " + Photo_ImagePath);
File f = new File(Photo_ImagePath);
if (f.exists())
{
System.out.println(" EEEEEEEEEEXXXXXXXXIIIIISSSSSSSTTTTTTT ");
try {
if(f.delete() == true){
result = "Success";
}else{
result = "Failure";
}
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "Error";
}
}
System.out.println("deleting existing file " + result);
return result;
}
