I'm new to android and trying to create an app which has a file picker and plays a particular file. I have been able to create the intent to open files; however I'm not able to pass the file path from the file picker to the intent to open that same particular file. Code given below. Appreciate any help. thanks.
EDIT Adding lines I missed___
public class MainActivity extends ListActivity {
private List<String> item = null;
private List<String> path = null;
public String root = "/mnt/usbhost0";
public TextView myPath;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myPath = (TextView) findViewById(R.id.path);
getDir(root);
}
public void getDir(String dirPath)
{
myPath.setText("Location: " + dirPath);
item = new ArrayList<String>();
path = new ArrayList<String>();
File f = new File(dirPath);
File[] files = f.listFiles();
if (!dirPath.equals(root))
{
item.add(root);
path.add(root);
item.add("../");
path.add(f.getParent());
}
for (int i = 0; i < files.length; i++)
{
File file = files[i];
path.add(file.getPath());
if (file.isDirectory())

You should pass the filePath to your DecryptTask. Add a constructor to it, and add the filePath, so you can initialize your videoFile2Play with the valid path. At the moment, your file is not initializing anything, that's why the intent is not starting/showing anything.
Add a constructor like so:
public class DecryptTask extends AsyncTask<String, String, String> {
String filePath;
public DecryptTask(String filePath){
this.filePath = filePath;
}
#Override
protected String doInBackground(String... params) {
try {
decrypt(this.filePath); //<--- Add filePath as param of decrypt method
} catch (InvalidKeyException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
} catch (NoSuchPaddingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
then, use the filePath you got inside the decrypt() method.

then finally i call it in my homescreen class. with an intent
Intent intent = new Intent(Homescreen.this, UpdateService.class);
startActivity(intent);
UpdateService is a Service. It is not an Activity. To start a service, you call startService(), not startActivity().
As UpdateService is a service you have to start it by startService() method like #CommonsWare mentioned above. Also don't forget to add your service in Manifest file.
UpdateService is not an activity, It's a class that is extending services.
I think u r a very beginner.
Please go to Udacity and learn the concepts before tingling with android, otherwise, u will waste lot of your time in finding a copy-paste solution.
On my android app, I have my own BaseAdapter, in this I have a click button listener with the following code:
btnShareFacebook.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
videoMoreLayout.setVisibility(View.GONE);
final String id = videoIDs[position];
videoActions = new VideoActions();
hfu = new HttpFileUpload(videoPathURL[position], token);
final ProgressDialog pDialog = new ProgressDialog(activity);
pDialog.setMessage("Preparing video to share...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
if (!isOnline()) {
Toast.makeText(activity,
activity.getString(R.string.noInternetConnection),
Toast.LENGTH_SHORT).show();
} else {
try {
String arr[] = videoPathURL[position].split("/upload/videos/");
final String finalVideoName = (arr[arr.length-1]);
File DoutFile = new File(
Environment.getExternalStorageDirectory() +
File.separator + "vidytape_shared" + File.separator + finalVideoName);
if(!DoutFile.exists()){
pDialog.show();
String downloadResult = videoActions.downloadToShare(token, activity, id, videoPathURL[position], finalVideoName);
if (downloadResult.equalsIgnoreCase("POST_FAILURE") || downloadResult.equalsIgnoreCase("FAILURE_102")) {
Toast.makeText(
activity,
activity.getString(R.string.someErrorOccurred),
Toast.LENGTH_SHORT).show();
}
/*if(hfu.Download_File_To_Share(finalVideoName, videoPathURL[position])){
Toast.makeText(activity, "OK", Toast.LENGTH_LONG).show();
//pDialog.dismiss();
} else {
Toast.makeText(activity, "ERRO", Toast.LENGTH_LONG).show();
}*/
}
pDialog.dismiss();
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("video/*");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(DoutFile));
share.putExtra(Intent.EXTRA_TEXT,
"" + activity.getResources().getString(R.string.app_name));
share.setPackage("com.facebook.katana");
activity.startActivity(share);
} catch (Exception e) {
pDialog.dismiss();
Toast.makeText(
activity,
activity.getString(R.string.facebookNotInstalled),
Toast.LENGTH_LONG).show();
}
}
}
});
Now here you have the function downloadToShare from the class VideoActions:
public String downloadToShare(String token, Activity activity, String videoID, String videoPath, String videoName) {
this.token = token;
this.activity = activity;
this.videoId = videoID;
this.videoPath = videoPath;
this.videoName = videoName;
DownloadToShareClass downloadAction = new DownloadToShareClass();
try {
return downloadAction.execute().get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
return null;
} // Close download
And now the downloadToShare class:
class DownloadToShareClass extends AsyncTask<String, String, String> {
String response = null;
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(activity);
pDialog.setMessage("Preparing video to share...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected String doInBackground(String... args) {
HttpFileUpload hfu = new HttpFileUpload(videoPath, token);
hfu.Download_File_To_Share(videoName, videoPath);
return "SUCESSFULLY";
}
} // Close DownloadClass
Now the download_file_to_share:
boolean Download_File_To_Share(String fileName, String urlToDownload) {
boolean downloadResult;
try {
downloadResult = DownloadFileToShare(fileName, urlToDownload);
return downloadResult;
} catch (MalformedURLException e) {
return false;
} catch (IOException e) {
return false;
}
}
And for the last the DownloadFileToShare:
// Download video
boolean DownloadFileToShare(String filename, String urlToDownload)
throws MalformedURLException, IOException {
BufferedInputStream in = null;
FileOutputStream fout = null;
try {
URL url = new URL(urlToDownload);
in = new BufferedInputStream(url.openStream());
fout = new FileOutputStream(
Environment.getExternalStorageDirectory() +
File.separator + "vidytape_shared" + File.separator + filename);
byte data[] = new byte[1024];
int count;
while ((count = in.read(data, 0, 1024)) != -1) {
fout.write(data, 0, count);
System.out.println(count);
}
} finally {
if (in != null)
in.close();
if (fout != null)
fout.close();
}
return true;
}
My Problem is as you can see on my BaseAdapter code, I'm showing a progress dialog, but it only is shown after all the rest finish (the video download). What is the problem here ? I want that the progressDialog shows when the video is being downloaded...
Thanks in advance
I've found a solution to my own problem. From my BaseAdapter I changed my click listener code to the following and it's working perfectly now:
btnShareFacebook.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
videoMoreLayout.setVisibility(View.GONE);
hfu = new HttpFileUpload(videoPathURL[position], token);
final ProgressDialog pDialog = new ProgressDialog(activity);
pDialog.setMessage(activity.getResources().getString(R.string.preparingVideoToShare));
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
if (!isOnline()) {
Toast.makeText(activity,
activity.getString(R.string.noInternetConnection),
Toast.LENGTH_SHORT).show();
} else {
try {
String arr[] = videoPathURL[position].split("/upload/videos/");
final String finalVideoName = (arr[arr.length-1]);
final File DoutFile = new File(
Environment.getExternalStorageDirectory() +
File.separator + "vidytape_shared" + File.separator + finalVideoName);
if(!DoutFile.exists()){
pDialog.show();
(new Thread(new Runnable() {
#Override
public void run() {
final String a = hfu.Download_File_To_Share(finalVideoName, videoPathURL[position]);
activity.runOnUiThread(new Runnable() {
public void run() {
if (!a.equalsIgnoreCase("ok")){
pDialog.dismiss();
Toast.makeText(activity,
activity.getResources().getString(R.string.someErrorOccurred),
Toast.LENGTH_LONG).show();
} else {
pDialog.dismiss();
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("video/*");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(DoutFile));
share.putExtra(Intent.EXTRA_TEXT,
"" + activity.getResources().getString(R.string.app_name));
share.setPackage("com.facebook.katana");
activity.startActivity(share);
}
}
});
}
})).start();
} else {
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("video/*");
share.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(DoutFile));
share.putExtra(Intent.EXTRA_TEXT,
"" + activity.getResources().getString(R.string.app_name));
share.setPackage("com.facebook.katana");
activity.startActivity(share);
}
} catch (Exception e) {
if(pDialog.isShowing()){
pDialog.dismiss();
}
e.printStackTrace();
Toast.makeText(
activity,
activity.getString(R.string.facebookNotInstalled),
Toast.LENGTH_LONG).show();
}
}
}
});
I hope it can help someone too.
Can you add code to show progressbar in onPreExecute in class DownloadToShareClass which extends AsyncTask ?
Please refer to http://developer.android.com/reference/android/os/AsyncTask.html
From the above link --
onPreExecute(), invoked on the UI thread before the task is executed. This step is normally used to setup the task, for instance by showing a progress bar in the user interface.
class DownloadToShareClass extends AsyncTask<String, String, String> {
private ProgressDialog mdialog;
public DownloadToShareClass(yourActivity activity) {
mdialog = new ProgressDialog(activity);
}
#Override
protected void onPreExecute() {
mdialog.show();
}
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
return null;
}
#Override
protected void onPostExecute(Void result) {
if (mdialog.isShowing()) {
mdialog.dismiss();
}
}
}

I have an file list and when a file is clicked its contents are displayed in an EditText. That file is set as currentFile. If the user tries to open a new file before saving the old one they are shown a save dialog. The OK button on the dialog should save the current working file but instead saves it as the file the user is trying to open. Where is the problem in my code that's causing the currentfile to be saved over the new one trying to be opened.
public boolean exists;
public File currentFile;

Third line of openFile(): you change currentFile before you conditionally ask the user if he wants to save currentFile before opening the new file. Change currentFile when you actually open another file, rather than before, and you won't have this problem even accidentally.
