Android :: Select A File From Droid Memory To Do Some Action On It?
Feb 15, 2010
I want to transfer a file into android dev's SD memory and read the file for parsing it.
But i don't know how to transfer a file into the emulators SD Card.
Also I don't know which api is to be used to browse for the file from the application.
This app provides the user to show it where he has kept the file which the app has to parse.
Which api does android provide for file management using a UI.
Thanks in advance.

I am customizing native phonebook application as a third party application which can be launched by the same intent as the native application. I have installed that application in my G1 phone. When I have clicked on Contacts icon in launcher menu it a menu pops out and asks me to select which app to lauch i.e., native contacts or my customized contact application. I have selected my application and I have also selected to use this selection as my default choice. After that system never put a pop-up and whenever I clicked on contacts it launches my customized application.
Now my problem is, I do not know how do I change this setting i.e., tell the phone to put the pop-up again so that I can select native app or my app?
Does anyone has any idea?

I am a new member and a relatively new owner of an X10i. Overall I am happy with the phone but I am hoping some can answer a question. When I press the home button (middle one) I get a prompt to select to 'Complete Action using Home or Timescape' This is quite annoying. I want the default action to be Home (not Timescape) but despite ticking the box in the prompt it still pops up this box.

I thought that Action was preeminent during intent resolution and if the intent had the same action as the intent filter, it would be considered a match regardless of data, if the filter did not specify anything. So I was very surprised to find that supplying action+data where filter had only action, causes it to fail. In the code below, if you comment out line 47 so that data is *not* sent, only then it resolves correctly. To get it to work with the data (an id that is simply a String), what mime type should I specify in the intent filter?

I have downloaded a file from HttpConnection using the FileOutputStream in android and now its being written in phone's internal memory on path as I found it in File Explorer
/data/data/com.example.packagename/files/123.ics
Now, I want to open & read the file content from phone's internal memory to UI. I tried to do it by using the FileInputStream, I have given just filename with extension to open it but I am not sure how to mention the file path for file in internal memory, as it forces the application to close.

I have an application that requires about 24Meg of mp3 files as a core part of the app. If I store them in the /raw directory on the emulator, I run out of memory. I can store them on the SDcard, but my question is will they be included when I package the application for the marketplace, or do I need to have the user download the files after they have the app on the phone? Where are larger files typically stored in Android apps or are large files not usually included?

I'm trying to implement a Select All menu item for a ListView in a ListViewActivity. The relevant parts of my ListViewActivity: public class MyListViewActivity extends ListActivity browsed around stackoverflow.com and the google; the above is something that should work. But it isn't. setSelection(i) appears to be the method I want to call on ListView but it's not working as advertised. What am I doing wrong? Is this even possible on Android in code?

I use this method couples of occasion to load text file to display as help file. But I don't know why the following code didn't work. It seems to hang and logcat says "OutOfMemoryError"? All I did was break this out as an separate activity.
---xml---
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/helptab"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/helptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</ScrollView>
---code---
import java.io.DataInputStream;
import java.io.IOException; import java.io.InputStream;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Help extends Activity {
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);
InputStream iFile = getResources().openRawResource(R.raw.help);
try { TextView helpText = (TextView) findViewById(R.id.helptext);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
} catch (Exception e) {
} }
public String inputStreamToString(InputStream is) throws IOException {
StringBuffer sBuffer = new StringBuffer();
DataInputStream dataIO = new DataInputStream(is);
String strLine = "";
while ((strLine = dataIO.readLine()) != "") {
sBuffer.append(strLine + " ");
} dataIO.close();
is.close();
return sBuffer.toString();
}

New to Android and starting to work on file mgmt. I set up some subfolders on my SD card for pictures. I have been moving pictures from one folder to another, but I can only move one at a time. Is there a way to select multiple picture files and move them to another folder (like "Select All" with Windows)? This is the sequence I've been following: Use the Edit Icon in the Astro taskbar, select Move, then going to the directory folder I want to move them, and hit Paste. Moving one file at a time is taking for ever.

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

Is there an Android UI Library that has components like Action Bars and Dashboards? A lot of new applications seem to have these components, so I was hoping there was a solution available (either free or paid).

I woke up this morning to a song playing from my phone that I made with xPiano about 2 weeks ago. I have no idea why this file was activated and when I looked at my task killer, most of my phone's memory had been used up but no programs were running in the background. I've never seen it get this low even when using 20 programs at a time. I've been using a mixture of apps that I've downloaded off of my computer and through the market. Is there any way that someone has access to my device and can look through all of my files/folders? Are there any known hacks/Trojans/viruses that do this?

Does anyone know how to access the internal storage memory using ES File Explorer? I have tried going up and down the folder hierarchy and can never find it.I've read that Astro File Manager can access it but I prefer using ES File Explorer and don't want to have two file managers on my DI.I am surprised at this stage of Android that a file explorer is not included in the OS.
