[android-developers] Re: Resume my activity from thread
what i have understood from your query is that u have implemented the Runnable interface. if u have done so, u have to use an Handler object to get hold of the ui elements... if this does not help u, please explain your problem properly.

[android-developers] Re: Resume my activity from thread
Hi Mark, when your new book on 1.5 sdk ? :-)
Mark the problem born around intent ACTION_IMAGE_CAPTURE. Mainly I
need to capture an image from camera.
I tried to use ACTION_IMAGE_CAPTURE with the follow code:
final Intent imageCaptureIntent = new Intent
(MediaStore.ACTION_IMAGE_CAPTURE);
imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(new
File(Environment.getExternalStorageDirectory
(), test.jpg)));
startActivityForResult(imageCaptureIntent, RESULT_CAPTURE_IMAGE);
it work but the image resolution is too low and seem impossible get an
image with full resolution.
Then I found an other solution (the current). I created an activity
with implemented the
Runnable interface. Run func. check if new images are created from
camera app. I'd like kill the camera activty from my run func. when an
new image is found. Look below my code.
private void CaptureImage()
{
_bEndThread = false;
_thread = new Thread(this);
_thread.start();
ComponentName toLaunch;
toLaunch = new ComponentName
(com.android.camera,com.android.camera.Camera);
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setComponent(toLaunch);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
startActivity(intent);
}
public void run() {
Cursor c = managedQuery
(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,null,null,null,null);
int iNPics = c.getCount();
while(!_bEndThread){
try{
c = managedQuery
(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,null,null,null,Media.DATE_TAKEN
+ ASC);
if( c.getCount()iNPics ) {
c.moveToLast();
iNPics = c.getCount();
Uri ur = Media.EXTERNAL_CONTENT_URI;
_uri=Uri.withAppendedPath(ur, c.getString
(c.getColumnIndex(Media._ID)));
//
/* AND NOW ? I WANT RESUME MY ACTIVITY */
//
_bEndThread=true;
}
_thread.sleep(1000);
}
catch (Exception ex){
}
}
}

Only launch external applications when you are willing to give up control.
In the case of the camera, if you don't want to give up control, use the
Camera object and take the picture yourself.

All three books will be updated over the next several weeks, with two
being updated within about 10 days. The original Android book will take
longest, mostly because I want to get the other two in print.
Mainly I need to capture an image from camera.
You can do that yourself, with full control, without having to launch an
external activity, via the Camera object. _The Busy Coder's Guide to
*Advanced* Android Development_ has a chapter on this, and that should
be brought up to Android 1.5 in ~10 days.
It's not that hard, once you have the recipe, and then you have full
control over the user experience.
Then I found an other solution (the current). I created an activity
with implemented the
Runnable interface. Run func. check if new images are created from
camera app. I'd like kill the camera activty from my run func. when an

{
_bEndThread = false;
_thread = new Thread(this);
_thread.start();

toLaunch = new ComponentName
(com.android.camera,com.android.camera.Camera);
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
intent.setComponent(toLaunch);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|
Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);
startActivity(intent);
}
public void run() {
Cursor c = managedQuery
(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,null,null,null,null);
int iNPics = c.getCount();
while(!_bEndThread){
try{
c = managedQuery
(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,null,null,null,Media.DATE_TAKEN
+ ASC);
if( c.getCount()iNPics ) {
c.moveToLast();
iNPics = c.getCount();
Uri ur = Media.EXTERNAL_CONTENT_URI;
_uri=Uri.withAppendedPath(ur, c.getString
(c.getColumnIndex(Media._ID)));
//
/* AND NOW ? I WANT RESUME MY ACTIVITY */
//
_bEndThread=true;
}
_thread.sleep(1000);
}
catch (Exception ex){
}
}
}
I stand by my recommendation: use the Camera object and take the picture
yourself. If you need MediaStore to know about the picture, I'm sure
there is some way to do that (e.g., call insert()).
