Recently I have been having issues with viewing my email messages in the Yahoo Mail App. When I open some messages all is see is line after line of code instead of the message text. It doesn't seem to matter what the source email is (gmail, hotmail, etc). Some emails are ok some are not. Anyone else have this problem? Any fixes?

I have copied the bin+res folder and Manifest.xml file to a specified folder. and run the command :[apkbuilder.bat %FILE_NAME% -rf "./src_folderr"]. This command build the new .APK file with default keystore. But I want to build the APK with me generated keystore, with command line as this :[apkbuilder.bat %FILE_NAME% -rf "./src_folder" -storetype path_to_my_release_keystore.keystore] but it can not find my keystore with "java.security.KeyStoreException : release.keystore not found". How can I build APK file with my keystore file?

try {
FileOutputStream fOut = new FileOutputStream(sDir + sFile);
//write
fOut.write( sReport.getBytes() );
// Close output stream
fOut.flush();
fOut.close();
} catch (IOException e) {

I've installed Ant. From an existing Eclipse project I am able to generate the build.xml file from the command line using ant -update project. When I now try ant release I get this error: build.xml:65: java.lang.NullPointerException. This project builds fine under Eclipse. I have no idea where to even begin to figure this out. I wouldn't bother with this except that I need to use ProGuard later on (which I have not done yet).

View 1 Replies View RelatedI don't really know where to put this topic but anyways my problem is that i need to edit a line in a file.
So i think of something like this
su
Cd /data/data/foldernameofapp/
Edit "file.dat"
Edit line 4 "text here 2"
i want it to edit like this "text here 3"
Change only the number. or replace the hole line with a new line where i only changed the number. btw the best is if the script can change a line and not find text and change. Because the number in the text i want to change can vary from different numbers.
P.S i can use root explorer and open the file with a text editor and change it, this works but takes forever P.S.S i got root
What is the easiest way to read an xml file? How is the best way to store the information from the xml?
I have tried to find a good tutorial, but I just can't get it to work..
I have an xml file in /res/xml called myxml.xml which looks like this:
<?xml version="1.0"?> <school> <student> <fname>Ola</fname><lname>Nordmann</lname> </student> </school>
I just want a simple way to read and store.

I am new to Android and relatively new to Java so please bear with me. I have an XML file stored in the res/xml that I am trying to write to. I know how to read it using XmlResourceParser, but I have not been able to find a way to write to that file locally. Could someone point me in the right direction please.
View 2 Replies View RelatedI have developed a program that will allow android users to navigate through the files. But the problem is that when I use the "ls" command it doesn't make always a new line after each file but it places it in one line. Here is a screenshot
So my question is: Is there a way to make it list each file in new line? (using adb commands)
Can we align our text line by line(I mean whatever the text we have selected that should be aligned instead of the whole text) in android text-view dynamically!

View 2 Replies View RelatedI'm working on a game which will use projectiles. So I've made a Projectile class and a new instance is created when the user touches the screen:
@Override
public boolean onTouch(View v, MotionEvent e){
float touch_x = e.getX();
float touch_y = e.getY();
new Projectile(touch_x, touch_y);
And the Projectile class:
public class Projectile{
float target_x;
float target_y;
Path line;
public Projectile(float x, float y)
target_x = x;
target_y = y;
line = new Path();
line.moveTo(MyGame.mPlayerXPos, MyGame.mPlayerYPos);
line.lineTo(target_x, target_y);
So this makes a Path with 2 points, the player's position and and touch coords. My question is - How can you access points on this line? For example, if I wanted to get the x,y coords of the Projectile at the half point of the line, or the point the Projectile would be at after 100 ticks (moving at a speed of X pixels/tick)? I also need the Projectile to continue moving after it reaches the final point. Do I need to use line.addPath(line) to keep extending the Path?
I managed to get the Projectiles moving in a straight line, but they're going in strange directions. I had to fudge some code up:
private void moveProjectiles(){
ListIterator<Projectile> it = Registry.proj.listIterator();
while ( it.hasNext() ){
Projectile p = it.next();
p.TimeAlive++;
double dist = p.TimeAlive * p.Speed;
float dx = (float) (Math.cos(p.Angle) * dist);
float dy = (float) (Math.sin(p.Angle) * dist);
p.xPos += dx;
p.yPos += -dy;
The Angle must be the problem. I'm using this method, which works perfectly:
private double getDegreesFromTouchEvent(float x, float y){
double delta_x = x - mCanvasWidth/2;
double delta_y = mCanvasHeight/2 - y;
double radians = Math.atan2(delta_y, delta_x);
return Math.toDegrees(radians);
However, it returns 0-180 for touches above the center of the screen, and 0 to -180 for touches below.
I know I can set android:singleLine="false" to set text to multi-line in a button. but can I set where to break into a new line instead of Android do it? I tried "ab" but doesn't work.

Anyways I need to create an AVD with the command line can someone please tell me the steps or tell me somewhere I can read up on this.

I'm running Mac OSX and each time I try to run layoutopt, for example, the terminal returns, *-bash: cmd: command not found. Also, is it okay to have my SDK located in the Developer directory and my android project in some unrelated directory when using these tools?
