Try this:
Open a command prompt window and type 'adb kill-server' (Without quotation marks). When it's done, type 'adb start-server'
If that doesn't work, try restarting eclipse, your computer and your device. I've had this problem before, and usually one of these steps solves it.

Check your code, there is an error in your XML file!!!!
Hint: line of repeated code near the start...
One thing to learn about coding is... debugging is a big part of it.

Hi people, I am newbie , trying to learn android developing.
So i was making this app. which uses the camera client android clicks a picture and then sets it as wallpaper, as per the user's request.
But when i try to install it on my phone (Samsung Galaxy y duos ). It says application not installed. I am not able to understand why. I have also added the permissions on the Android manifest. Please do help me out. I will be attaching the xml for the camera app and its Class.
THE JAVA CLASS...
Code:
package com.example.done;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.ImageView;
public class Camera extends Activity implements View.OnClickListener {
Button camera;
ImageButton done;
ImageView wallpaper;
int cameraData = 0;
Intent i;
Bitmap pic;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.photo);
intial();
camera.setOnClickListener(this);
done.setOnClickListener(this);
InputStream is = getResources().openRawResource(R.drawable.abc);
pic= BitmapFactory.decodeStream(is);
int cameraData = 0;
Intent i;
}
private void intial() {
// TODO Auto-generated method stub
camera = (Button) findViewById(R.id.camera);
done = (ImageButton) findViewById(R.id.imgTile);
wallpaper = (ImageView) findViewById(R.id.imagButt);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.camera:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, cameraData);
break;
case R.id.imagButt:
try {
getApplicationContext().setWallpaper(pic);
} catch (IOException e) {
e.printStackTrace();
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
Bundle e = i.getExtras();
pic = (Bitmap) e.get("data");
wallpaper.setImageBitmap(pic);
}
}
}[/CODE]

ThankYou in advance
Please add your manifest to the OP too, the issue is most likely in it (The first thing that comes to my mind is that your app has a higher android:minSdkVersion than your device's version of android)
Also, did you export a signed apk?
Are you using Eclipse ?
If you do, just make a right click on your project name and choose "Run As --> Android Application" to launch it on your connected device with adb enabled.
If you want to export a signed apk, right click your project's name and choose "Android tools --> Export Signed Application Package..." and follow the instructions in the daemon.
Manifest

Actually, if i hit run. It would start up my emulator(It is installng on that perfectly).
But i have not connected my emulator to the webcam, so it would forceClose.
I have also set my emulator to Qvga.
And yup, the i have attached the manifest too.:good::good:

Add this permission to your manifest :
Code:
<uses-permission android:name="android.permission.CAMERA"/>
What version of Android is your device running ? You might wanna change this line
Code:
android:targetSdkVersion="8"
to :
Code:
android:targetSdkVersion="17"
if you want your app to support devices running ics & jellybean and/or be able to use the latest APIs (download the android 4.2.2 sdk platform if eclipse throws an error)
EDIT : you also have a whitespace in this line, remove it :
Code:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CA [COLOR="DarkRed"]here [/COLOR]PTURE
It would be helpful if you paste in here the output of the console. It has nothing to do with the java code since it is being installed in the emulator.
Still not working

You're giving us the output for the emulator here... We need to see the output for when you install it on an actual device as it's where your problem is.
I attached a screenshot.
I hope that helps.
So as i told you, everything was working fine. Until i added the camera app. But for experiment's sake, i deleted the app's xml, java and the activity from the manifest. But still the same result.
As i.told you, the camera app is a sub app in my phone..
The whole app contains some more app. But even then its not working:thumbup::thumbup:

Problem Solved
Hey fellas.
I thought that changing the phone, would solve the problem,
So i used samsung s2 instead of samasing galaxy y duos.
And the app worked....
But i am not able to determine the reason.
Why don't you post the output of the console? You have been asked several times :good:
You will not find anything in the console.
As eclipse installes the apk in my emulator. In the emulator, it installs perfectly. So everything in the console is positve. Anyways i have already attached the console output in the previous page. And if you need the logcat. I will provide you.
Anyways, a great thanks for your concern

Could you provide us your android manifest?
Maybe you need to set a lower minSdkVersion. (Although it says "Parsing error" on my Samsung Galaxy Ace if there is a wrong minSdkVersion)
I have copied the manifest in the previous page. I have tried putting minsdk on qvga adpi.
But it didnt work..

Ah. Ok. Thanks.
The minSdkVersion is the minimum Android version which has to be installed on the device.
8 is the code for Android 2.2.
Which Android version is running on your device? Maybe you will need to set it to a lower value.
i have 2.3.6

Hi I have used ListFragment and simple ArrayAdapter quite often. And now I want to try some more by customizing BaseAdapter. But something happened, the List is not showing at all. I don't have any error (the Logcat also saying there're no error). But I debug it, and found out that getView() in my customized BaseAdapter is not called. I wonder why?
Here's the snippet:
#favorite_list_layout
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ListView
android:id="@+id/favorite_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
#favorite_list_item
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical">
<TextView
android:id="@+id/favorite_text"
android:layout_margin="5dp"
android:layout_marginLeft="10dp"
android:layout_marginBottom="0dp"
android:textSize="35sp"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/favorite_text_details"
android:layout_marginLeft="10dp"
android:layout_marginTop="0dp"
android:layout_marginBottom="5dp"
android:fontFamily="sans-serif-light"
android:textSize="18sp"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
#FavoritesFragment
Code:
public class FavoritesFragment extends ListFragment {
[user=439709]@override[/user]
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
//... setting variable favList, and this code is working. favList is not empty and there're no error
setListAdapter(new FavoriteAdapter(getActivity(), favList));
}
}
FavoriteAdapter, extends BaseAdapter
Code:
public class FavoriteAdapter extends BaseAdapter {
private Context ctx;
List<DMapData> list;
public FavoriteAdapter(Context context, List<DMapData> list) {
this.ctx = context;
this.list = list;
System.out.println("constructor executed!");
}
[user=439709]@override[/user]
public int getCount() {
return list.size();
}
[user=439709]@override[/user]
public Object getItem(int i) {
return list.get(i);
}
[user=439709]@override[/user]
public long getItemId(int i) {
return i;
}
[user=439709]@override[/user]
public View getView(int position, View convertView, ViewGroup parent) {
System.out.println("GetView is executed"); //But it's not.
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.favorite_list_item, parent, false);
}
TextView favText = (TextView) rowView.findViewById(R.id.favorite_text);
TextView detailsText = (TextView) rowView.findViewById(R.id.favorite_text_details);
DMapData data = list.get(position);
System.out.println("DMapData from List");
favText.setText(data.getName());
detailsText.setText(data.getDetails().length()<=50? data.getDetails() : data.getDetails().substring(0, 51).concat("..."));
System.out.println("At the end of getView()");
return rowView;
}
}
Thanks
The id of the ListView has to be a special one so that the ListFragment can find it:
Code:
android:id="@android:id/list"
Hmm...
I have tried to change the id like your code. But, still not shown up. Is there anything I should do with my ListFragment?

Do you inflate your layout?
Code:
[user=439709]@override[/user]
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_layout, container, false);
}
I always set the adapter in onCreate but there shouldn't be a difference.
Your layout looks like that now, right?
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<ListView
android:id="android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
EDIT: Oh, add an orientation to the LinearLayout or replace it by a RelativeLayout.
And change the ListView heigth to match_parent.
Yupz. But still no different.
Here's my changed code. I have changed not using my customized adapter again, but instead using SimpleAdapter.

Try this layout:
Code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/list"
android:layout_alignParentTop="true"
android:fastScrollEnabled="true" />
<ProgressBar
android:id="@android:id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
style="?android:attr/progressBarStyle" />
</RelativeLayout>
It's working for me.
Did you try to write all entries to the logs? Do you get an output?
You know what? This is really make me laugh all the time, that it's because what I think is right but actually not. The list that I provided for my ListView is actually empty. Your layout tell me, because there's always the progressbar. Thank you very much for your help. :highfive:

Yes its quite noticeable
As he was saying he could not see error in Log while debugging. My advice to use log was for his future projects.

I am using Android's SlidingTabColors sample in my application layout. I have three tabs initialized. Due to the default tab layout all the tabs have same layout. I have searched everything about setCustomTabView; but unable to get it implemented. I wanted to know where should i call this method? What statements are to be used? I have used a switch statement in the onViewCreated method of the ContentFragment class. The code I have written in the onViewCreated method is posted below:
Code:
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
TextView title = (TextView) view.findViewById(R.id.item_title);
int indicatorColor = args.getInt(KEY_INDICATOR_COLOR);
switch (indicatorColor)
{
case Color.RED:
{
SlidingTabLayout mSlidingTabLayout = (SlidingTabLayout) view.findViewById(R.id.sliding_tabs);
mSlidingTabLayout.setCustomTabView(R.layout.speed_test, R.id.hello1);
}
case Color.GREEN:
title.setText("Subject: " + args.getCharSequence(KEY_TITLE));
case Color.BLUE:
title.setText("Header: " + args.getCharSequence(KEY_TITLE));
}
}
[CODE]
The speed_test.xml file is posted below:
[CODE]
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
