I have spent much time trying to resolve this trivial problem but seem to be going in circles even after reading many tutorials and previously asked questions.
I am a novice at programming but want to get better and believe that learning through mistakes is the best way.
Can someone please help identify the problem with this code and what can be done in order to allow the pictures taken by the device's camera to be saved onto the phone afterwards rather than being discarded and previewed.
Thanks in advance!

because you're returning null return null; in your getOutputMediaFileUri
try this instead
public void onClick(View v) {
switch (v.getId()) {
case R.id.ibTakePic:
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, getOutputMediaFileUri());
startActivityForResult(i, cameraData);
break;
}
}
private Uri getOutputMediaFileUri() {
File imagesFolder = new File(Environment.getExternalStorageDirectory(), "MyImages");
imagesFolder.mkdirs();
File image = new File(imagesFolder, "image.jpg");
return Uri.fromFile(image);

I'm new to programming, and I'm creating an app with texttospeech and I wanna be able to share the tts output as an audio file to other apps like whatsapp for example. I have heard about synthesizetofile() but I don't know anything about it.
Here's my code:
Main Activity class

}
}
});

#Override

File myDir = getApplicationContext().getFilesDir();

Anyone who helps, would be appreciated very much!
My app only extracts name and address from the location selected from google places API. I want it to extract phone numbers as well. How do I do that? Below is my MapActivity.JAVA that enables the google places api and shows nearby places. I followed a tutorial and it only had extracted name and address, so I'm stuck now. Any help would be much appreciated. Thanks :)

I'm making an android application, when clicking on a button it opens the camera however after taking the picture the image doesn't save. I want to be able to save it into my gallery album.
public void onClickbtnCamera(View v){
Intent intent1 = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Uri uriSavedImage=Uri.fromFile(new File("/storage/emulated/0/DCIM/Camera/"));
intent1.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(intent1,3);
}
You are passing in a directory in EXTRA_OUTPUT. EXTRA_OUTPUT needs to point to a file:
package com.commonsware.android.camcon;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import java.io.File;
public class CameraContentDemoActivity extends Activity {
private static final int CONTENT_REQUEST=1337;
private File output=null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent i=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir=
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
output=new File(dir, "CameraContentDemo.jpeg");
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(output));
startActivityForResult(i, CONTENT_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == CONTENT_REQUEST) {
if (resultCode == RESULT_OK) {
Intent i=new Intent(Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(output), "image/jpeg");
startActivity(i);
finish();
}
}
}
}
(from this sample project)

}
private void initialize() {

ib = (ImageButton) findViewById(R.id.ibTakePic);
but = (Button) findViewById(R.id.bSetWall);
but.setOnClickListener(this);
ib.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bSetWall:
try {
getApplicationContext().setWallpaper(bmp);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
case R.id.ibTakePic:
i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, 1);
break;
}
}
#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 extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
iv.setImageBitmap(bmp);
}}
}
why is the below code force closes on using built in camera in android
project?
Because you are missing setContentView in onCreate before calling initialize().
You will need to set layout for current Activity before calling findViewById to access views from current screen xml.do it as in onCreate:
...
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout_name);
initialize();
....
Title says it all, Im new to SQL and trying to change the selection the user makes but placing buttons in the screen and not use the MENU button. Seems like the buttons aren't instantiated but the code looks right to me...what am i missing??

Now the menu buttons work great so not sure whats up...Thanks for looking
The menu buttons work great because the switch statement for it is proper.
Your onClick is not working properly however. This is because The cases are for different ids than what the buttons provide. You want R.id.editbutton and R.id.deletebutton instead.
Your method should look like:
public void onClick(View arg0) {
switch (arg0.getId())
{
case R.id.editbutton: //updated
Intent addEditContact =
new Intent(this, AddEditCountry.class);
addEditContact.putExtra(CountryList.ROW_ID, rowID);
addEditContact.putExtra("name", nameTv.getText());
addEditContact.putExtra("cap", capTv.getText());
addEditContact.putExtra("code", codeTv.getText());
addEditContact.putExtra("newb", newEt.getText());
startActivity(addEditContact);
break;
case R.id.deletebutton: //updated
deleteContact();
break;
}
}
}
